After a successful launch from Cape Kennedy on July 16th, the Apollo 11 astronauts were tasked on July 17 at 12:17 pm with a three-second burn of the Service Module Propulsion System (SPS). This was one of four scheduled midcourse corrections programmed for the flight. Later that afternoon the Apollo 11 astronauts did a color television broadcast from the spacecraft, showing viewers back home what the Earth looked like from 147,300 miles away. Their broadcast lasted 36 minutes and Command Module pilot Michael Collins described the food that the astronauts ate in the zero-gravity environment of the Apollo 11 spacecraft.

The launch from the Cape had been so successful that the last two midcourse corrections were not needed on Apollo 11’s journey to the moon.

Researchers have been devising numerous new ways to deliver medications and other therapies more directly to patients to make it less invasive and more targeted for specific ailments and diseases.

MIT chemical engineers have come up with one of the latest of those with the development of what are called nanoemulsions that can be used to create materials to deliver medication that can be absorbed by or injected into the skin.

Nanoemulsions are very tiny droplets of a liquid suspended within another, similar to the mixture formed when one shakes a bottle of salad dressing of vinegar and oil, researchers said.

A team led by Patrick Doyle, a professor of chemical engineering at MIT, discovered how to convert liquid nanoemulsions to a gel when they reach body temperature--98.6 degrees Fahrenheit or 37 degrees Celsius. He and his team said this discovery could be useful for developing materials that can deliver medication when rubbed on the skin or injected into the body.

“The pharmaceutical industry is hugely interested in nanoemulsions as a way of delivering small molecule therapeutics,” he said in a press statement. “That could be topically, through ingestion, or by spraying into the nose, because once you start getting into the size range of hundreds of nanometers, you can permeate much more effectively into the skin.”

Less Energy, Same Stability

A simple way to create an emulsion is to add energy, such as in the example of shaking salad dressing. The drops in the emulsion become smaller and more stable if more energy is used.

Nanoemulsions are some of the most stable of these type of liquid mixtures, with droplets that have diameters of 200 nanometers or smaller, researchers said. They also can carry larger payloads—i.e., medications or sunscreens, for example—because they have a higher ratio of surface area to volume, researchers said.

Doyle and the researchers in his lab have been develop strategies for the past few years to create nanoemulsions with less energy than they typically need. This could help adapt these technologies for large-scale industrial manufacturing, researchers said.

Detergent-like chemicals called surfactants can speed up the formation of emulsions, researchers said. However, many of the surfactants that have previously been used for creating nanoemulsions are not FDA-approved for use in humans.

Doyle and his students chose two surfactants that are uncharged, which makes them less likely to irritate the skin, and are already FDA-approved as food or cosmetic additives. They also added a small amount of polyethylene glycol (PEG), a biocompatible polymer used for drug delivery that helps the solution to form even smaller droplets, down to about 50 nanometers in diameter.

“With this approach, you don’t have to put in much energy at all,” Doyle said “In fact, a slow-stirring bar almost spontaneously creates these super small emulsions.”

Active ingredients can be mixed into the oil phase before the emulsion is formed, so they end up loaded into the droplets of the emulsion, he added.

From Emulsion to Gel

Once they had developed a low-energy way to create nanoemulsions using nontoxic ingredients, the researchers added a step that would allow the emulsions to be easily converted to gels when they reach body temperature, they said. They achieved this by incorporating heat-sensitive, tri-block polymers called poloxamers, or Pluronics, which are already FDA-approved and used in some drugs and cosmetics, Doyle said in the press statement. Their molecular structure and characteristics allow for the transformation to happen, he said.

Researchers describe their work in a paper in the journal Nature Communications.

To demonstrate their work, researchers created nanoemulsions that remained stable for more than a year, they report in the paper. They also incorporated ibuprofen into the solutions to show that medications could indeed be delivered in this way.

Researchers now are turning their attention to how to incorporate active pharmaceutical ingredients into the gels they created from the nanoemulsions. They believe these gels could be useful for topical medications, such as those applied to heal burns or other injuries of the skin, or cosmetic uses.

Beckhoff Automation is offering greater integration of OPC UA communication technology into its recently released TwinCAT Scope software. OPC UA and analytics tools are becoming increasingly important as advanced automation tools proliferate. The information must be presented in a clear and efficient manner, and the machine control system also has to cover a wide range of other smart components.

TwinCAT Scope software provides optimum support for integrated data acquisition across heterogeneous system environments. A standardized OPC UA communication channel enables this charting tool to analyze data from diverse sources such as TwinCAT controllers and third-party components.

TwinCAT 3 Scope consists of Scope View for the graphical display of signal curves and Scope Server for the actual data logging. The Scope Server  be installed on a target device for autonomous logging (without the View component if desired) or on the corresponding engineering system together with Scope View for remote logging. The latter solution offers the advantage that no additional software needs to be installed on the target device. As a result, no updates to TwinCAT controllers are required, and devices without TwinCAT software do not require modification to display their data graphically in Scope View.

Vendor-Independent Secure Data Collection Via OPC UA

For logging measured signals, the Scope Server features a TwinCAT-specific ADS channel as well as support for another standardized communication channel in the form of an OPC UA client. The widespread use of OPC UA in automation technology enables TwinCAT Scope to acquire and display measured data in a vendor-independent way. With OPC UA, this can be achieved reliably and securely, especially if certificates are used.

The TwinCAT Target Browser  ̶  which is used to manage connected data sources in TwinCAT Engineering  ̶  has been expanded with OPC UA support. It enables browsing in the namespaces of connected OPC UA servers. This feature can be used to select the desired variables for logging by the Scope Server with configuration options for certificate-protected access.

OPC UA Facilitates Interoperability

Beckhoff integrated OPC UA into TwinCAT Scope software to provide customers the tools they need to implement IIoT and Industrie 4.0 concepts. “Controls engineers and plant managers in all industries want to harness the benefits of big data, so they are working to gather as much data as possible from individual machines up to multiple production lines across global operations,” Daymon Thompson, automation product manager for North America at Beckhoff Automation, told Design News. “However, the difficulties of communicating between controllers from multiple vendors can create a barrier to effective data acquisition. As a platform-independent communication protocol, OPC UA eliminates these problems by providing standardized and secure data exchange among devices, machines and industries.”

Thompson noted that OPC UA can be integrated from the sensor to the cloud, and it is recommended in Reference Architecture Model Industrie 4.0 (RAMI 4.0) for implementation as a communication layer. “Beckhoff now includes OPC UA as a server and client in nearly every machine controller that we produce to facilitate open interoperability with third-party devices. This increases our ability to complement our machine control capabilities with advanced connectivity tools for troubleshooting, machine optimization and data analytics, including TwinCAT 3 Scope software.”

Scope View and Scope Server

Thompson noted that the TwinCAT Scope is an integrated digital oscilloscope that provides graphical display of signal curves. “This software-based charting tool is extremely useful for machine commissioning and process optimization, and it uses two main components for these purposes,” said Thompson. “Scope View, provides graphical display of measuring signals through integration in the TwinCAT XAE programming environment and Microsoft Visual Studio. Operators can view a variety of signal curves and create complex representations, including X vs. time charts, XY plots, bar charts, digital displays and others, to measure and analyze frequency responses more effectively.”

The second component, Scope Server provides the visual display of the data. “To maximize the benefits of Scope View, TwinCAT Scope gathers all available measurement data in heterogeneous systems with Scope Server,” said Thompson. “The TwinCAT 3 Scope Server prepares data for visual display in TwinCAT 3 Scope View. It can be used for autonomous data recordings in distributed systems within production, plant or machine networks. This component performs manufacturer-independent data logging with both a TwinCAT-specific communication channel via ADS protocol and a standardized communication channel implemented with MQTT or OPC UA.”

Data Security Is Built In

OPC UA integrates several enhanced security mechanisms to ensure secure transport of encrypted data from end to end. This comes through two mechanisms. “The first mechanism of OPC UA’s security is a secure data channel and authenticated clients via x.509 certificates, which means the server and client have to trust each other via Public/Private Key Pairs,” said Thompson. “This is possible with either self-signed certificates or certificates from a trusted Certificate Authority.”

The second mechanism is access-level security at the namespace and node level. “This means that data down to the individual data point can be secured via groups or user permissions,” said Thompson. “Additionally, the data can be encrypted using a Secure Sockets Layer to prevent man-in-the-middle attacks. This does not necessarily guarantee the entire network is secure, but the data certainly are.”

July 16, 1969

The Apollo 11 Saturn V lifts off with astronauts Neil A. Armstrong, Michael Collins and Edwin E. Aldrin Jr. at 9:32 a.m. EDT July 16, 1969, from Kennedy's Launch Complex 39A.(Image source: NASA)

It began at 9:32 am Eastern time on July 16, 1969. The mighty Saturn V rocket launched the Apollo 11 spacecraft from Pad 39A at the Kennedy Space Center in Florida. On board were mission commander Neil Armstrong, Command Module pilot Michael Collins, and Lunar Module pilot Edwin “Buzz” Aldrin. Apollo 11 would be the third time that astronauts would leave Earth orbit—Apollo 8 had orbited the moon in December of 1968, and in May Apollo 10 had served as a dress rehearsal, orbiting the moon and testing the systems and lunar lander without actually touching down on the lunar surface. Now, all was ready for humans to set foot on the moon.

2 hours, 44 minutes into the flight, after one-and-a-half Earth orbits, the S-IVB third stage of the Saturn V reignited for a second burn of 5 minutes, 48 seconds. The thrust served to place Apollo 11 into a translunar orbit. Then, the command and service module, or CSM, named “Columbia” separated from the third stage. Columbia rotated around to face the spacecraft-lunar module adapter, or SLA, which contained the lunar module, or LM, named “Eagle”. Columbia and Eagle docked for the first time and the lunar module was extracted from the SLA. The S-IVB stage separated and another firing of its rocket injected it into heliocentric orbit 4 hours, 40 minutes into the flight.

Apollo 11 was on its way to the moon!

For any company relying on parts manufactured by third parties, the threat of counterfeiting is very real. Where there is money to be made with fake, substandard parts, there will be people willing to produce them. As a result, there is a lively industry for the detection of counterfeit goods and parts.

At the consumer level, anti-counterfeit technology could include a holographic tag on a garment – an expensive collector’s football jersey, for example -- to reassure the customer shelling out big bucks that the garment is authentic. It might be about placing tiny, covert scanners inside the products themselves. In some cases, chemical signatures are used in the manufacturing process and then scanned to ensure all the parts of a product or machine are authentic.

The problem with anti-counterfeit technology has traditionally been that once a method for detecting counterfeiting becomes established, the counterfeiters determine how to get around it. This is particularly true of overt methods of counterfeit detection, such as holographic tags.

“Overt protections reassure the consumer that the football jersey with the hologram tag is likely to be authorized and authentic, but they telegraph to the counterfeiter exactly what to spoof, so those holograms, alas, are no longer trustworthy,” Dr. Sharon Flank, CEO of InfraTrac, told Design News. “You can buy your own in rogue marketplaces. Covert protections have the advantage of working behind the scenes.”

Anti-counterfeit Measures Are Failing

Unfortunately, even some covert methods are becoming easier to get around, particularly with the wide availability of 3D scanners, which means that techniques such as laser etching or tiny barcodes are no longer reliably covert. Manufacturers may be staking their brand reputation, and the safety of their customers, on the authenticity of parts and materials. Products produced via additive manufacturing are particularly vulnerable, since the printing is often outsourced, creating even more spots in the supply chain where trouble in the form of poor-quality counterfeits can slip in

Forensic measures – generally considered the most secure methods to detect fakes --  have historically required expensive lab equipment manipulated by expensive experts, but recent advances in photonics have enabled an explosion of new portable, easy-to-use instruments that put forensic-quality science in the hands of field personnel, with near-instant authentication capability.

New Measures to Protect Additive Manufactured Parts

As more complex parts are created with additive manufacturing, methods are required to authenticate parts created by multimaterial processes involving the laser bed powder fusion (LBPF) process. Maryland-based InfraTrac recently partnered with Belgium-based SLS 3D printer manufacturer Aerosint to ensure the integrity of multimaterial parts created with LPBF.

The partnership became possible when Aerosint recently debuted the first multi-powder SLS 3D printer. Since InfraTrac’s anti-counterfeiting technique embeds a different material -- preferably during the printing process – it can only be used in a multimaterial print processes. Until Aerosint’s innovation, LBPF was not a multimaterial process.

InfraTrac’s tagging model uses commodity taggants for scalability. A taggant is a substance with a chemistry that features unique codes that are nearly impossible to replicate. Optimally, taggant is placed in a small subsurface spot during the print. Selecting a single, highly detectable taggant and dispersing it throughout the product (in filament or mixed into pellets or powders) may seem like a good idea, but placing taggant everywhere makes it easier for counterfeiters to locate it and copy it. Instead, InfraTrac uses compatible chemicals as taggants, as part of the print process, and hides them in a small covert spot so they’re nearly impossible for counterfeiters to replicate.

Anti-counterfeiting Needs to be Integral to Additive Manufacturing

Flank stresses that the forensic counterfeiting detection methods must be easy to use if they’re to be reliable. As a result, the prototypes produced by the partnership between InfraTrac and Aerosint have chemical signatures are read with off-the-shelf handheld spectrometers: near-infrared spectrometers for polymers and x-ray fluorescence spectrometers for metals. The signatures are then checked for a match using chemometric algorithms, with support from InfraTrac’s partner Camo Analytics.

“Complexity is the enemy of security: difficult procedures invite work-arounds,” said Dr. Flank. “That’s what makes us reuse passwords even when we know we shouldn’t. Security procedures that align with existing processes are most likely to be adopted, and less likely to be circumvented. Applying taggant or codes should be part of the standard print or manufacturing workflow, not an add-on.  Detection should take seconds, with inexpensive, portable, off-the-shelf equipment.”

Every Company with a Brand Needs a Security Plan

While many anti-counterfeiting technologies are focused on copyright and patent protections, there are far fewer focused on safety and supply chain integrity. While patent-related technologies generally authenticate the software and the printing processes, anti-counterfeiting for additive manufacturing needs to be integral to the final printed product, even if it’s a multimaterial part.

“In recent years, aerospace and defense, automotive, and heavy equipment manufacturers have all been looking for good security options for LBPF, especially for metals,” said Flank. “Every company with a brand and customers to protect needs a security plan, and as AM gains traction, they know AM security will be important as well.”

For now, the two companies are creating simplistic demonstrator parts made from polymer and metal that integrate “fingerprinting” sites based on a powder formulation developed by InfraTrac. Going forward, InfraTrac and Aerosint plan to create more safety solutions for more materials, more part shapes, and more printer types, guided by the needs of their customers.

Graphene is known as a wonder material for scientists, with myriad uses due to its unique combination of light weight, strength, flexibility, and high electrical conductivity.

One of its drawbacks, however, is that synthesis of the carbon-based material is complex and costly, inspiring researchers around the world to find cheaper, easier, and faster ways to do it.

A collaborative effort between researchers in Australia and India has developed a way to synthesize graphene using eucalyptus bark, potentially making the material more cost-effective and accessible to global industry. (Image source: RMIT University)

From Australia

Researchers now have discovered a natural source of a key agent for synthesizing graphene in eucalyptus trees, an abundant species in Australia.

The research—a collaboration between scientists at RMIT University in Australia and the National Institute of Technology in Warangal, India—developed a method that uses eucalyptus bark to synthesize graphene that is cheaper and more sustainable than current ones, researchers said.

“Traditionally, synthesis of graphene requires highly controlled environments and toxic reducing agents, which involves lot of complex and costly operations,” Suresh Bhargava, a distinguished professor at RMIT, told Design News. “Thus, we have looked for a cheaper, eco-friendly, and affordable way to produce graphene.”

Researchers seem to have found that in eucalyptus bark extract, which can used as a reducing agent for the reduction of graphene oxide to graphene, he told us. This is the first time this material has been used in the fabrication of graphene, researchers said.

“Previously, eucalyptus tree leaves were used to produce oils, which contained polyphenolic compounds,” Bhargava told Design News. “Naturally, these polyphenolic compounds act as reducing agents, which drives us to use this idea in our synthesis.”

Virtually No Cost

Chemical reduction is the most common method for synthesizing graphene oxide, allowing for the production of graphene at a low cost in bulk quantities. Instead of using toxic, chemical reducing agents, the work now provides an option to use a natural, virtually no-cost material, he said.

“The advantages are the eucalyptus trees are abundant and no cost involved using theses bark waste, and do not produce any toxic waste in the synthesis process,” Bhargava told Design News. Researchers published a paper on their work in the journal ACS journal Sustainable Chemistry and Engineering.

Graphene produced using this method in tests already has produced quality and performance on par with graphene synthesized in more tradition ways, researchers reported.

They also believe their method will drive the cost of making graphene down significantly, from $100 per gram to just 50 cents, which would make it more accessible and available to industries worldwide for new technology development.

Now that researchers have successfully tested the graphene they’ve developed using eucalyptus bark in supercapacitors, they plan to use it in other applications as well, such as batteries or in a biocompatible material, Bhargava told us.

“Further, it can be used in various applications from water filtration to renewable energy [and] sensors,” he said.

The team plans to continue its work to take the research out of the lab and into the marketplace, Bhargava told Design News.

“We know the secrets and intellectual property,” he told us. “Also, we want to make graphene-based composites for further improving its performance in various applications. In true sense, the sky is the limit for R&D in this area.”

Scientists long have looked to hydrogen-based fuels and fuel cells as a cleaner alternative to fossil fuels for energy production.

However, one drawback has been that hydrogen gas is extremely flammable when mixed with air, which means any automobile or other vehicle using this type of fuel needs to have a reliable and super-fast sensor to ensure safety.

Researchers in Sweden believe they’ve solved that problem with the development of an optical nanosensor that they said responds the fastest to date when hydrogen has escaped into the air.

The sensor—developed by a team at Chalmers University of Technology--is based on an optical phenomenon called a plasmon, which occurs when metal nanoparticles are illuminated and capture visible light. This effect causes the sensor to change color when the amount of hydrogen in the environment changes, researchers said.

“We use arrays of palladium-gold alloy nanoparticles as transducer that can be read-off optically,” Ferry Nugroho, a researcher at the Department of Physics at Chalmers who worked on the research, told Design News. “These particles are then covered with thin polymeric film.”

Researchers at Chalmers University of Technology have developed a hydrogen sensor that can detect hydrogen in the air faster than any invented to date. This is key to the use of hydrogen-based energy sources, as the element is highly flammable with only minimal contact with air. (Image source: Yen Strandqvist)

Key to the sensor’s design is that it is encapsulated in plastic, which has a twofold purpose. It increases the sensor’s response time speeding the uptake of the hydrogen gas molecules into the metal particles where they can be detected, he said. It also acts as an effective barrier to the environment, preventing any other molecules from entering and deactivating the sensor.

“In the work we used tandem polymers comprising PTFE and PMMA,” Nugroho told Design News. “The former modifies the interaction between hydrogen atom and nanoparticle surface, so that hydrogen can goes in and out the nanoparticle quicker, while the latter acts as sieve that prevents other gas molecules than hydrogen pass through.”

The plastic barrier is key to the performance of the sensor and is a point of differentiation over similar technologies created to date, Nugroho said.

“Unlike today's hydrogen sensors, our solution does not need to be recalibrated as often, as it is protected by the plastic,” he said in a press statement.

The Need for Speed

The automotive industry has been eyeing the use of hydrogen fuel cells to replace fossil fuels in cars and provide a cleaner source of energy. However, in order for this to become a reality, automobiles also must have a hydrogen sensor with the ability to detect 0.1 percent hydrogen in the air in less than a second to pass rigorous safety standards.

Detecting hydrogen is no easy feat, as the gas is invisible and has no smell but at the same time is quite volatile and very flammable. To the latter point, it requires only 4 percent hydrogen in the air to produce what’s called oxyhydrogen gas—also known as knallgas—which will catch fire at the smallest spark.

This means researchers really had to focus on the sensor’s ability to very quickly detect hydrogen in the air at even the smallest amounts, said Christoph Langhammer, professor in the Chalmers Department of Physics who also worked on the research. They accomplished this almost by accident when they discovered that the plastic they used to protect the sensor also make its response time faster, he said.

This knowledge inspired researchers to work more quickly to develop a solution to the problem, Nugroho said in the statement. “We wanted to find the ultimate combination of nanoparticles and plastic, understand how they worked together and what made it so fast,” he said. The team published a paper on its work in the journal Nature Materials.

Researchers plan to continue their work “to further optimize the detection limit and response speed by tailoring the nanoparticle-polymer combination,” Nugroho told Design News.

While the sensor is aimed at detecting hydrogen to promote the use of hydrogen fuels for the automotive industry, there also are organizations in other industries that could benefit from an efficient hydrogen sensor—including electricity networks, chemical and nuclear power plants, and medical diagnostics.

Researchers also are eyeing efficient fabrication as part of their strategy, hoping to use 3D-printer technology to manufacture the sensors for industry use, they said.
