Amorphous silicon is a good semiconductive material for many applications. It is a member of the large class of silicon compounds which comprise silicon clusters, silane oligomers, poly(siloxanes), and poly(silanes). The last mentioned polymers are of considerable interest because of their unusual electrical and photoelectrical properties. It has been shown that in these polymers the effect of ...
The role of a series of functionalized graphene additives in power cable insulation in suppressing the growth of electrical treeing and preventing the degradation of the polymer matrix has been investigated by density functional theory calculations. Bader charge analysis indicates that pristine, doped or defect graphene could effectively capture hot electrons to block their attack on cross-link...
Polymer additives reliably prevent incongruent melting of sodium acetate trihydrate when temperature-cycled over multiple thousands and freezing cycles.
Introduction. The photobleaching, or reduction in fluorescence quantum yield, of fluorescent dyes upon continuous excitation is a commonly encountered problem. The mechanism of photobleaching in fluorescent dyes has been shown to be complex, sensitive to environmental and excitation conditions, and specific to each dye. Nevertheless, two primary pathways are invoked to explain the photodegradat...
