of indium(III) triflate also yielded3, while no conversion was observed when hard Lewis acids, such as boron trifluoride or trifluoromethanesulfonic acid (HOTf), were added, suggesting that the halophilicity of the additives is crucial. The addition of silver salts resulted in a low conversion...
(and basic) than a water molecule, because the negatively charged oxygen on the hydroxide ion carries greater electron density than the oxygen atom of a neutral water molecule. In practical terms, this means that a hydroxide nucleophile will react in an SN2 reaction with bromomethane much faster...
, Au surface) to form solid-molecule SFLP. This SFLP configuration enables the activation of H2 and subsequent hydrogenation of imines and nitriles.20 In contrast to the aforementioned SFLP types, amine-functionalized SFLP systems circumvent the reliance on hydroxyl groups to generate OVs, ...
The term "antibody" refers to an immunoglobulin, or derivative thereof, having an area on the surface or in a cavity which specifically binds to and is thereby defined as complementary with a particular spatial and polar organization of another molecule. The antibody can be monoclonal or polyclona...

Lewis Structure : The Lewis structure of a compound is the most precise approximation of the shape of a compound and the angles between the adjacent groups. This takes into consideration the relative repulsions between the substituents and between the lone pairs which is why the angle is also ...
Calculation of the structure and extinction limit of a methane-air counterflow diffusion flame in the forward stagnation region of a porous cylinder The paper addresses itself to the numerical representation of the structure of counterflow methane-air diffusion flames, with the use of complex chemistry...
