White dwarfs, with masses just above the Chandrasekhar limit (1.4 solar masses), can violently collapse into small (104 km radius) and very dense (ρ = 1017 kg/m3) magnetars that can produce B-field...

Pasteur was the first to realize Earth's homochirality. Consequently, he attempted to design experiments revealing a mechanism that would expose life's chiral preference. Some of these experiments involved the application of magnetic fields to chemic

A mechanism is presented concerning electrolysis of deuteriated water with a palladium cathode that is infused with deuterium (palladium deuteride) resulting in the formation of small amounts of radioactive tritium, excess energy (more than allowed b

Benzophenone, a material that is common in biomass and coal, resists pyrolysis up to 400 °C. However, when the compound is reduced with potassium metal in tetrahydrofuran (THF) followed by solvent removal, the C−H bonds, as well as the CO bond, ar

EPR studies in tetrahydrofuran, reveal that the one electron reduction of 1-(9-methyl-9H-fluoren-9-yl)-4-methylbenzene via electron transfer from cesium metal produces an anion radical that has a large affinity for the cesium cation. The affinity of

The room temperature potassium reduction of 1,2,3-triscyclooctatetraeneoxypropane, in hexamethylphosphoramide (HMPA), yields an anion radical, which disproportionates so strongly to the dianion diradical that the anion radical cannot be observed via

The anion radical of mono-bromo-[8]annulene was generated in the absence of ion association, and the EPR-measured spin densities can be explained in terms of the odd electron occupying MOs: Ψ4‘ = [2√(n2 + 1)]-1(ψ1 + nψ2 − ψ3 − nψ4 + ψ5
