This reduces the energy barrier for H-atom abstraction and H-atom migration reactions from tertiary CH when compared to primary and secondary CH bonds. Several studies exist on the higher temperature combustion
I have had student groups build banners on the history of chemistry, design HyperCard stacks (there is an old one for you) on the elements and their compounds, create videos on elements, create 3D models of molecules and ancient Greek matter theorists, do interviews of experts on the history...
Strong light–matter interaction in cavity environments is emerging as a promising approach to control chemical reactions in a non-intrusive and efficient manner. The underlying mechanism that distinguishes between steering, accelerating, or decelerating a chemical reaction has, however, remained unclear, ...
In multiphase chemical kinetics, the rate of change in complex systems can be described by resolving mass transport and chemical reactions at the molecular process level [1, 2]. While the underlying physical and chemical principles are well understood, the individual processes are inherently coupled ...
The polymerisation of alkoxysilanes, called the sol-gel process, proceeds through a series of consecutive hydrolysis and condensation reactions36,37. The amount of water contained in waterlogged wood should be sufficient to activate silane molecules and allow them to condense and chemically bind to ...

Exothermic and/or endothermic chemical reactions in combination with phase change materials can produce output temperature(s) within strict tolerances without requiring expensive an
While it may be possible to conduct this series of steps in a single reactor, it can also be conducted in two reactors, the first reactor is designed for purely thermal reactions and, the second is designed to contain a suitable acid catalyst on a solid support. Another approach to forming...
Most typically the reactions and mixing occurs in less than one second. As noted above, it is typical and preferred to use more concentrated solutions of aluminum and phosphorus so that on neutralization a precipitate is formed immediately. It has been found that the apparent average shear rate...
