A chemical claw machine bends and stretches when exposed to vapors
ScienceDaily - Biochemistry Research News
by
8h ago
Scientists have developed a tiny 'claw machine' that is able to pick up and drop a marble-sized ball in response to exposure to chemical vapors. The findings point to a technique that can enable soft actuators--the parts of a machine that make it move--to perform multiple tasks without the need for additional costly materials. While existing soft actuators can be 'one-trick ponies' restricted to one type of movement, this novel composite film contorts itself in different ways depending on the vapor that it is exposed to ..read more

A new material derived from graphene improves the performance of neuroprostheses
ScienceDaily - Biochemistry Research News
by
8h ago
Neuroprostheses allow the nervous system of a patient who has suffered an injury to connect with mechanical devices that replace paralyzed or amputated limbs. A study demonstrates in animal models how EGNITE, a derivative of graphene, allows the creation of smaller electrodes, which can interact more selectively with the nerves they stimulate, thus improving the efficacy of the prostheses ..read more

Moving from the visible to the infrared: Developing high quality nanocrystals
ScienceDaily - Biochemistry Research News
by
3d ago
Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum ..read more

Implantable LED device uses light to treat deep-seated cancers
ScienceDaily - Biochemistry Research News
by
3d ago
Certain types of light have proven to be an effective, minimally invasive treatment for cancers located on or near the skin when combined with a light-activated drug. But deep-seated cancers have been beyond the reach of light's therapeutic effects. To change this, engineers and scientists have devised a wireless LED device that can be implanted. This device, when combined with a light-sensitive dye, not only destroys cancer cells, but also mobilizes the immune system's cancer-targeting response ..read more

A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process extracts europium directly from fluorescent powder in used energy-saving lamps in much higher quantities than existing methods. The researchers are now working on expanding their approach to other rare earth metals. They are in the process of founding a start-up to put the recycling of these raw materials into practice ..read more
