Green plastic production made easy

A one-step method enables scalable and more environmentally friendly production of plant-derived plastic monomers, paving the way towards the mass production of a sustainable alternative to petroleum-based materials.

Scientists develop way to identify topological materials

In the decades since they were first theorized, scientists have suggested that the exotic properties of topological materials—that is, materials that maintain their electrical properties even in the face of radical temperature ...

SLAC's high-speed 'electron camera' films molecular movie in HD

With an extremely fast "electron camera" at the Department of Energy's SLAC National Accelerator Laboratory, researchers have made the first high-definition "movie" of ring-shaped molecules breaking open in response to light. ...

Novel approach promises ready access to hard-to-study proteins

DNA and the genome, we know, provide the blueprint for life. But it is the proteins made according to the genome's instructions that are the nuts and bolts of living organisms, providing the molecular building blocks for ...

Hold the mustard: What makes spiders fussy eaters

It might be one of nature's most agile and calculating hunters, but the wolf spider won't harm an insect that literally leaves a bad taste in its mouth, according to new research by a team of Wake Forest University sensory ...

Harnessing microorganisms for smart microsystems

A research team at the Department of Mechanical Engineering at Toyohashi University of Technology has developed a method to construct a biohybrid system that incorporates Vorticella microorganisms. The method allows movable ...

Chemical reaction

A chemical reaction is a process that always results in the interconversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions. Different chemical reactions are used in combination in chemical synthesis in order to get a desired product. In biochemistry, series of chemical reactions catalyzed by enzymes form metabolic pathways, by which syntheses and decompositions ordinarily impossible in conditions within a cell are performed.
