Why is carbon dioxide more soluble than oxygen? Dipoles: Dipoles are formed when a covalent bond contains atoms with significantly different electronegativities. This results in a greater electron density around the more electronegative element, resulting in a partial negative charge on that element an...
The catalyst is withdrawn daily with a vanadium, nickel, and carbon content that is representative on a macroscale of what is found throughout the entire reactor. On a microscale, individual catalyst particles have ages from that of fresh catalyst to as old as the initial catalyst charge to ...
Azim wants to find out whether metal X , which makes a 3+ charge in a compound is more reactive than metal Y which makes a 2+ charge in a compound. He adds metal X to a nitrate salt of Y and is able t How do the electrons help in predicting the chemical properties of elements?
NUS chemists have developed a light enhanced, nickel catalysed method for carbon-hydrogen (C-H) bond functionalisation in organic molecules. The replacement of "H" in C–H bonds with otheratomsor substituents is one of the most coveted ways to create new and usefulmolecules. However, while t...
Catalytic reduction of CO2 over Cu-based catalysts can produce various carbon-based products such as the critical intermediate CO, yet significant challenges remain in shedding light on the underlying mechanisms. Here, we develop a modified triple-stage

Base metal electrodes are commonly nickel-based. The significant issue at hand from a production standpoint is how the electrode metals react chemically at the high temperatures required to fire the ceramic dielectric materials; the noble metal electrode systems can tolerate the presence of more ...
More significantly, graphene edge sites are more reactive and are responsible for the covalent interactions of several chemical species. The graphene structure and characteristics can be largely retained after edge functionalisation with minimal damage to the carbon basal plane, unlike graphene functional...
