Contemporary polymer network materials, such as hydrogels and elastomers, require not only enhanced mechanical properties but also adaptability during or after use. Polymer mechanochemistry, which ...

Traditional chemistry is so last year. Welcome to the world of mechanochemistry, where reactions that were thought impossible – indeed, that are impossible when attempted in more conventional ...

Enzyme mechanisms are the chemical transformations, and the steps within them, generated by enzymatic action on substrates. The mechanism of enzyme catalysis is similar in principle to other types ...

They earn units by reducing emissions below “business-as-usual” – the emissions that would occur without the project. Just like emissions trading, for such mechanisms to work a tonne reduction must ...

Iron photocatalysis, in conjunction with a cooperative radical mechanism, enables the anti-Markovnikov hydrochlorination of unsaturated feedstocks, using light as an energy source.

Summary: Researchers have identified a genetic mechanism that regulates behavioral adaptations to emotional experiences by forming R-loops, unique RNA:DNA structures that activate target genes. The ...

A simple form of ratchet mechanism is shown in Figure 8-1. The amount of backward motion possible varies with the pitch of the teeth. This motion could be reduced by using small teeth, and the ...

It operates via a molecular "cut and paste" mechanism driven by special proteins, known as recombinases. The integron system has been researched a lot. Some bacteria gain new resistance very fast ...

Defense mechanisms are rooted in Freud’s theory of personality.According to his model, the mind has three dueling forces: the id (unconscious and primitive urges for food, comfort, and sex), the ...
