salinity conditions are desirable for efficient energy conversion. Here, the authors address the challenge by modifying the distribution of electrostatic potentials in the linkages of covalent organic framework membranes and apply the material to the conversion of low-grade waste heat into electrical ...

(Fig.2b). The obtained ellipsometry data can be used to calculate SAM coverage in terms of adsorbed molecules per unit area (Fig.2cand Supplementary Note3). The growth does not reach a clear saturation even after 168 h and resembles standard monolayer growth model (Supplementary Note4), ...
more than 10 middle schools in Beijing, Hebei, Shandong and other regions of China, earning extensive acclaims from teachers and students. To explore students’ understanding of “the properties and transformation of substances,” we chose three units (unit 4, unit 5 and unit 7) for research....

The system was equipped with a Gerstel MPS 2 autosampler, a Twister Thermal Desorption Unit (TDU), and a Gerstel Cooled Injection System Programmable Temperature Vaporization (PTV) inlet (Gerstel, Mülheim an der Ruhr, Germany).The compounds adsorbed on stir bars were thermally desorbed in the ...
In this regards, thermodynamically stable Si-rich SixC1-x materials can be used in solar cell applications without requiring the expensive pure grade silicon or pure grade silicon carbide. In this work, we have used density functional theory (DFT) to examine the stability of various polymorphs ...
