... two different molecules very quickly, at speeds of tens of times per second. But in spite of these properties, researchers have recently observed hydrogen-bond exchange taking place in real-time.
... Douvris. "But we found a way to take a C-F bond that you can do very little with and break ... temperature, swapping their carbon-fluorine bonds for carbon-hydrogen bonds. The silylium catalyst performs ...
... of Teflon pans. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful ... breaks the C-F bond and converts it to a carbon-hydrogen bond, rendering it harmless to the environment. ...
... biological building blocks. One key element is a bond involving titin, a giant among proteins ... Simulations have pointed toward a network of tight hydrogen bonds linking titin and telethonin as a source ...
... cooled to very low temperatures. This is why hydrogen only solidifies at just 14 degrees above ... new compound – SiH4(H2)2 – in which the hydrogen bonds are unusually weak and which may become a metal ...
... in chains - because they interact with each other strongly via hydrogen bonds.
"You can visualize it as mini-freight trains of chain-bonded water molecules flying at high speed through a ...
... a window on protein-water rearrangements during the folding process, such as breaking protein-water-hydrogen bonds and replacing them with protein-protein-hydrogen bonds, Gruebele said. The remaking ...
... so fundamental, it may have broader ramifications to biological systems that depend on hydrogen bonds," he says.
The breakthrough was enabled by laser-based laboratory techniques at the University ...
... with all these arginine guanidinium groups, approaches the cell, it basically does a handshake using hydrogen bonds with cell surface constituents that are in the membrane," Wender said. "In essence, ...
... method is much more convenient than using neutrons and could be used for routine formulation evaluation.
Hydrogen bonds are responsible for many of water’s properties; they make water a liquid at ...

Hydroxide ions form extra hydrogen bond to speed through water
Water`s unrivaled omnipresence and the crucial role it plays in life drives scientists` to understand every detail of its unusual underlying properties on the microscopic scale.
... uses molecular oxygen, the O2 we breathe, to break carbon-hydrogen bonds and release energy. This reaction, better known as combustion, also pairs each broken-off, positively charged ...
... . They also detected organic molecules at the moon in March. Organic molecules have carbon-hydrogen bonds, and are found in living organisms, and in comets.
