A new catalyst material developed by chemists at MIT provides key insight into the design requirements for producing liquid fuels from carbon dioxide, the leading component of greenhouse gas emissions. The findings suggest a route toward using the world's existing infrastructure for fuel storage and distribution, without adding net greenhouse emissions to the atmosphere.
The approach used by regulators to initially screen new chemical products for toxic effects is wrong almost half the time, according to scientists at the University of North Carolina at Chapel Hill. They have proposed an improvement that could increase accuracy to as much as 85 percent, saving millions of dollars and years of development time for new drugs and other products while improving safety.
Evonik Industries, a German chemical company that is a major producer of amino acids for animal nutrition, is venturing into one of the field’s final frontiers: fermentation-based production of methionine.
Bio-based is ready for blast off with news that thermoplastic resin producer Braskem, are partnering with space manufacturing company Made in Space on green plastics for 3D printers which can operate in zero gravity. This innovation, a year in the planning, is important as it can give astronauts greater autonomy by enabling them to fabricate parts and tools using 3D printing, which can save time and costs.
The election of Donald Trump as U.S. president and a Republican-controlled Congress portend significant impacts to the chemistry enterprise. Given Republican's campaign statements, academic researchers are likely to feel a federal research funding pinch while the chemical industry could benefit from new energy policies and relaxed regulation.
The recovery of carboxylic acids from fermentation broth is one of the main bottlenecks for the industrial production of bio-based esters. This paper proposes an alternative for the recovery of carboxylates produced by fermentations at pH values above the pKa of the carboxylic acid. In this approach, the aqueous carboxylate anion is recovered using anion exchange, followed by desorption and esterification with CO2-expanded alcohols.
What if you could take one of the most abundant natural materials on earth and harness its strength to lighten the heaviest of objects, to replace synthetic materials, or use it in scaffolding to grow bone, in a fast-growing area of science in oral health care? This all might be possible with cellulose nanocrystals, the molecular matter of all plant life. As industrial filler material, they can be blended with plastics and other synthetics. They are as strong as steel, tough as glass, lightweight, and green.
