When CdTe is introduced as the second component, an absorption shoulder appears at 650 nm due to the smaller bandgap of CdTe. The absorption tail extends beyond 700 nm as a result of the charge transfer transition from the CdTe valence band to the CdSe conduction band. Recombination ...

This concept has driven the development in the extraction of major components (typically chitin) from crustacean shells and the transformation of them into useful products. Owing to ca. 7 wt% of bio-fixed nitrogen in chitin, the utilization of chitin or its derivatives provides an alternative ...
From the analysis of Section 3.1, it can be concluded that the PCE of GNTs is higher than that of GNRs. In other words, if the same amount of light projects to the nanoparticles, the GNTs can absorb more optical energy and convert it into thermal energy, compared to GNRs. When in ...
Shiramize and Toste [1] proposed a method to produce p-xylene with 2,5-dimethyfuran (derived from lignocellulosic biomass) and acrolein (from glycerol, a side product of biodiesel production) through four step-reactions with an overall yield of 34%. Lyons et al. [2] used ethylene (...
during which there is also a part of the form of heat generation through the non-radiative transition back to the ground state [14] and (2) the participation of a sensitizer, which absorbs energy from the ground state to the excited state and then transfers the absorbed energy to the activ...
Introduction Thermo-chemical conversion of lignocellulosic biomass is one of the most promising methods for the production of various chemicals and bio-oil to replace fuels obtained from the processing of fossil resources [1]. The formed products can be divided into gaseous and liquid fractions. The...
Based on the spectroscopic data obtained from FT-IR, 1H NMR, 13C NMR, and 1H-15N HSQC, the amide and carboxylic acid groups were unambiguously distinguishable. The multiple proton signals between 7.0–8.5 ppm in 1H NMR were correctly assigned to the active amide protons (–C(=O)-NH2) ...
The Idea of Operation and the Control Algorithm of the Supporting System The presented solutions based on the current modulator have a positive effect on the waveforms of currents drawn by the diode rectifier from the grid. In this chapter, a solution will be proposed to further improve the ...
