Splet25. jan. 2014 · The present work attempts to perform research, from the phonon structure to thermal conductivity of PbS, by using first-principles. We first calculate phonon dispersions and phonon density of states (DOS) of cubic PbS. Then we investigate the heat capacity of PbS. Based on these, we calculate the lattice thermal conductivity of PbS, … Spletpred toliko urami: 9 · The NM’s motion trajectories were tracked in the absence and presence of different urea concentrations in 1× PBS up to 300 mM (see Figure 2ci), ...

Splet24. nov. 2024 · Energy transfer process among QDs was revealed by measuring the lifetime of different emission bands in PL spectrum and the energy transferred from smaller QDs with broader bandgap to bigger QDs with narrow bandgap. Temperature-dependent PL and the corresponding lifetime decay curves of PbS QD-doped glasses were analyzed. reds bad season
