Light fragments have been observed as a new class of products from heavy-ion collisions at intermediate energies. Two mechanisms which produce such light fragments are well understood but is seems difficult to characterize a third one identified within a moving source framework. From a large set of inclusive data, a few features are extracted and eventual signatures of a multifragmentation proc...
Beaklike SnO2 nanorods were synthesized by a vapor-liquid-solid approach using Au as a catalyst. The nanorods grow along the [10 1] direction and the beak is formed by switching the growth direction to [1 12] through controlling the growth conditions at the end of the synthesis. The photoluminescence (PL) spectrum of the nanorods exhibits visible light emission with a peak at 602 nm. The field-...
The emission of ultraweak light from cells is a phenomenon associated with the oxidation of biomolecules by reactive oxygen species. The indole moiety present in tryptophan, serotonin and melatonin is frequently associated with the emission of light during the oxidation of these metabolites. This study presents results for hypobromous acid (HOBr) oxidation of tryptophan as a putative endogenous...
