Electrochromic smart window for modulation of infrared heat
Published 2021“…The improved electrochromic performance is due the existence of Nd-Mo co-dopants that restrict the trapping of Li+ ions within the α-WO3 framework. This reduces the degree of crystallization of α-WO3 layer and improves the electronic conductivity by transferring excess electrons to the conduction band of the SnO2. …”

Ultralow-threshold two-photon pumped amplified spontaneous emission and lasing from seeded CdSe/CdS nanorod heterostructures
Published 2013“…Ultrafast optical spectroscopy verified that while the Auger processes in these heterostructures are indeed suppressed, ASE in these samples could also be strongly affected by a fast hole trapping process to the NR surface states. Lastly, to exemplify the potential of these seeded CdSe/CdS nanodot/nanorod heterostructures as a viable gain media for achieving two-photon lasing, a highly photostable microsphere laser with an ultralow pump threshold is showcased.…”

Chlorine and NaCl in hydrous basaltic melts
Published 2025“…Finally, measurements of the compositions of melt inclusions from Etna were used to calculate the activities of NaCl in the inclusions and the salinities of fluids with which the inclusions would be in equilibrium. From the trapping pressures of the inclusions and their compositions we find that decompression from 500 MPa to ∼50 MPa is accompanied, in this case, by a salinity increase from <1 wt% NaCl to ∼50 % NaCl.…”

Selective photoelectrochemical oxidation of glycerol to glyceric acid on (002) facets exposed WO3 nanosheets
Published 2024“…Compared to (200) facets exposed WO3 , a combination of experiments and theoretical calculations indicates that the superior performance of selective glycerol oxidation mainly originates from the better charge separation and prolonged carrier lifetime resulted from the plenty of surface trapping states, lower energy barrier of the glycerol-to-GLYA reaction pathway, more abundant active sites and stronger oxidative ability of photogenerated holes on the (002) facets exposed WO3 . …”
