Breaking reactivity barriers

The scope and productivity of an essential palladium-catalyzed coupling reaction that generates complex molecules has been improved thanks to A*STAR research that uses low-reactivity materials.

Pouring fire on fuels at the nanoscale

There are no magic bullets for global energy needs. But fuel cells in which electrical energy is harnessed directly from live, self-sustaining chemical reactions promise cheaper alternatives to fossil fuels.

Substrates change nanoparticle reactivity

(Phys.org)—Nanoscale materials tend to behave differently than their bulk counterparts. While there are many theories as to why this happens, technological advances in scanning tunneling microscopy (STM) have allowed researchers ...

Optimizing atomic neighborhoods for speedier chemical reactions

Scientists have discovered that for palladium-nickel catalysts, certain surface characteristics, measured at the atomic level, sped the creation of carbon dioxide from carbon monoxide. To reveal the optimal atomic neighborhood ...

Sewage could be a source of valuable metals and critical elements

Poop could be a goldmine—literally. Surprisingly, treated solid waste contains gold, silver and other metals, as well as rare elements such as palladium and vanadium that are used in electronics and alloys. Now researchers ...

Nanoparticles for clean drinking water

One way of removing harmful nitrate from drinking water is to catalyse its conversion to nitrogen. This process suffers from the drawback that it often produces ammonia. By using palladium nanoparticles as a catalyst, and ...
