Chemical reactions occur because bonds between atoms are either broken or formed. When atoms or molecules come together, they form new substances called compounds. These compounds can then undergo ...

'Click' chemistry allows for the linking together of chemical modules, however, there are currently no methods that also allow for facile 'declicking' to unlink them. Now, a method has been developed ...

Chemists at the National University of Singapore (NUS) have developed a methodology to enable coupling reactions for the ...

Reversing means to go back. Reversible changes are where a change to something can be undone again. The change is only temporary and the substance can be put back to how it was before. Irreversible ...

When recycling plastics, contamination and chemistry conspire to degrade the quality of each recycled generation. In a perfect world, a polymer could be converted to its monomer building blocks, then ...

In their function as cellular recycling plants, proteasomes fulfill a life-sustaining role in all cells -- including cancer cells. When the proteasomes become inhibited, cells suffocate in their own ...

The percentage yield shows how much product is obtained compared to the maximum possible mass. The atom economy of a reaction gives the percentage of atoms in reactants that form a desired product.

Although chromium itself is not an active element, its continuous dissolution enables a reversible surface transformation that keeps the Co-Cr spinel oxide electrocatalyst active and stable. This ...
