I've selected protease as the optimal enzyme for eliminating gluten formed from flour. Could you please provide insights on the best enzyme for removing gluten, dosing methods, and how to identify the suitable enzyme variant given that proteases have diverse types? This information is essential for my project aimed at resolving pipeline blockages induced by gluten from flour in the food industry using enzymes ..read more

https://www.theguardian.com/world/2024/mar/13/japan-cat-toxic-chemical-vat-fukuyama-nomura-plating-metal-plant It could be the opening scene from a new Marvel film. Residents of a Japanese city have been warned not to approach or touch a missing cat that appears to have fallen into a vat of toxic chemicals before scampering off. The search for the unlucky feline began after an employee of a metal plating plant in Fukuyama, western Japan, arrived at work to find a trail of yellowy-brown paw prints leading away from a container of hexavalent chromium, a highly acidic carcinogen. Touching th ..read more

Maybe a rudimentary question for yall but was not getting much useful information from diyers. I have a cooktop in a van with the normal heat resistant glass but due to the bumping around when driving as well probably to poor design quality of the glass it cracked. Rather than replace with another glass one which is liable to crack I thought why not replace with metal instead. The size I want is relatively small at 29x29cm. Thickness 1-3mm will do. In my naivety I did not consider the issue of warping at all and just bought standard 3mm mild steel since it was cheaper. Placing the metal in the ..read more

hi, can someone explain please whether there are steady metals.  The property I look for is about being steady across (nuclear) radiation,too. but as this issue does not fall inside the areas of my interests, I think i can easily make some mistakes. if this is a case, I kindly  request the correction and understanding.  Thanks ..read more

Hello, could someone please help me with this? Some reactions are spontaneous (with dG < 0) although they are endothermic (dH > 0). My question is: Is it possible to extract work from such a reaction? The process I understand to produce work  is to heat something in a contained space and transfer the heat pressure into kinetic energy with a turbine. (Sorry I know this is not very formal). For example, this reaction is a spontaneous endothermic reaction. NH4NO3 (s)   –>   NH4+ (aq) + NO3- (aq) Is there a way I can get my turbine to work with this reaction ..read more

QM calculations these days are so precise, at least for the simpler species, that electron orbital transition energy levels can be calculated with great precision. This in turn defines the (minimum?) frequency of the energising photon with similar precision. The probability of receiving an energising photon of exactly the required minimum energy seems to me to approximate to zero, and yet the excitation definitely happens. What happens to the mismatch between orbital energy change and photon energy ..read more

Can some one here explain how chemical compounds make up billions of chemicals? And why only 1% have been found and it takes a very long time to find new chemicals?       Only 1% of chemicals in the universe have been discovered. Here's how scientists are hunting for the rest.   The universe is flooded with billions of chemicals, each a tiny pinprick of potential. And we've only identified 1% of them. Scientists believe undiscovered chemical compounds could help remove greenhouse gases, or trigger a medical breakthrough much like penicillin did. But let ..read more

I put a pair of pure nickel strips in a solution of potassium carbonate 34% by weight to water and  applied a current and voltage to them reversing the polarity a couple dozen times.  and a dark black coating formed alternatingly on whichever electrode was the positive one. and the other electrode changed to a brighter nickel color. Heres a picture of one of the strips of nickel. the dark part on the right is what was in the solution. I also noted it has a voltage potential across it open circuit of about 1.23 to 1.38 volts. if I replace one of the nickel strips with a zinc strip and ..read more

I know that atoms or molecules near the surface of liquid or water may absorb from or lose its molecules/atoms to the surrounding. Does it also happen to solid? When two solids of the same kind or different kinds are touched, pushed, or rubbed against each other, could they exchange their molecules or atoms at the touching surface? Thanks for the concept ..read more
