The generation of h+ was further confirmed by the complete photodegradation of 4-CP during 48h. Moreover, the changes in FTIR and XPS spectrum of GO before and after reaction indicated the oxidization of epoxy and hydroxyl groups by holes or reduction by electrons was involved in the ...
TiO2 has attracted research interest because it is economical, non-toxic, ubiquitous, chemically stable across pH spectrum, and has suitable band edge positions [10]. In recent years, UV photodetectors (PDs) have garnered immense attention due to the extensive array of applications in optical ...
h. Moreover, the changes in FTIR and XPS spectrum of GO before and after reaction indicated the oxidization of epoxy and hydroxyl groups by holes or reduction by electrons was involved in the photoreaction. The photoreduction of Cr(VI) could was also observed in an oxisol with the existence...
The change in the UV spectrum coincided with the UV spec- trum of reduced GO (rGO)25. However, there was no obvious shift of the peak at ≈ 225 nm, compared to highly reduced rGO in which a peak shift to ≈ 270 nm was commonly observed, as the reduction of GO under the...
The addition of inositolhexaphosphate to stripped nitrosyl hemoglobin provokes strong changes in the visible absorption spectrum of the protein. The stoich... R Cassoly - 《Journal of Molecular Biology》 被引量: 48发表: 1975年 pH-Induced Shift in Hemoglobin Spectra: A Spectrophotometeric Comparison...
We have also used UV curing LEDs but the best results with BzF were obtained with a UV oven (Luzchem, LZC-1; Ottawa, Canada) which has a heat extraction fan, with UV spectrum peaking in the 300–400 nm band. In general, the intensity of UV illumination that can be achieved in these...
aEQUIS recognises that internationalisation can take many forms and that the degree of internationalisation will vary considerably across a broad spectrum of activities. EQUIS认为国际化可能采取许多形式,并且程度国际化横跨宽广的范围活动将可观地变化。 [translate] a氧化石墨烯(GO)在各种不同的还原条件下呈现...
In order to observe and evaluate changes in the solution properties, the parameters such as energy per pulse (mJ), rate of repetition (number of pulses/second) and irra- diation time (min) were monitored. A typical UV-VIS absorbance spectrum is provided in Fig. 1a and other ...
Compared to the two spectra, we can draw a conclusion that the addition of clavate-shaped ZnO will not affect the structure and properties of the original silk nor its own structure and properties. Fig. 3(b) represents the FTIR spectrum before and after soaking with a clavate-shaped ZnO ...
The spectrum of Au-ZnO sample clearly illustrates two peaks: one at the UV region around 380 nm and the other in the visible region around 550 nm. The peak in the UV region originates from the band edge absorption of ZnO and that in the visible range is due to the surface plasmon ...
