THERE is an increasing tendency on the part of organic chemists to apply the Berzelius dualistic theory, in a modified form, to organic compounds. In many theories of valency, individual groups are ...

Kinetex 2.6 µm Polar C18 combines C18 ligands with a polar-modified surface to enable superior retention of polar and nonpolar compounds while ensuring 100 percent aqueous stability.Click here for ...

The effect of long-chain polar compounds on the coefficient of kinetic friction under boundary conditions has been studied using the Boerlage four-ball friction apparatus in various modifications.

The density of ice is less than water. This is due to the water expanding as it is frozen because of the hydrogen forming an open type lattice. high surface tension relatively high viscosity All ionic ...

The first is the new Luna Omega Polar C18 stationary phase – a unique selectivity on an innovative silica particle that delivers a wide elution window and combined high retention for polar and ...

Cod liver oil and other fish oils are often used as dietary supplements because they contain nutrients such as omega-3 fatty acids, vitamin A, and vitamin D. It has been known for some time that these ...
