The paper describes one promising method and approach for the recycling, reuse, co-resource treatment of waste photovoltaic silicon lithium battery anode graphite. Specifically, this work considers preparation nano/micron carbide (SiC) from resources. Using activated carbon as a microwave susceptor over very short timeframe, research shows that β-SiC can be successfully synthesized using sinter...
In this study, the adsorption mechanism and hydroxyl radical ((•)OH)-initiated photocatalytic degradation mechanism of styrene onto different (TiO2)n clusters were investigated using density functional theory. Styrene, a typical model atmospheric volatile organic compound (VOC), was found to be readily adsorbed onto (TiO2)n clusters through its vinyl group with strong chemisorption. This sugges...
This paper describes the morphology, stoichiometry, microstructure and gas sensing properties of nano clustered SnOx thin films prepared by Sn evaporation followed by the Rheotaxial Growth and Thermal Oxidation (RGTO) process. Electron microscopy was used to investigate, in detail, the evolution of the films as the oxidation temperature was increased. The results showed that the contact angle, ...
Globular clusters will be present at high redshifts, near the very beginning of the galaxy formation process. Stellar evolution ensures that they will be much more luminous than today. We show that the redshift distribution at nano-Jansky levels should be very broad, extending up to the redshift of formation. A bracketing range of choices for the redshift of formation, spectral energy evolution...
Integrin-mediated adhesions are critical for stem cell differentiation, cancer metastasis, and the immune response [Hynes RO (2009) Science 326:1216-1219]. However, the mechanisms of early adhesion formation remain unclear, especially the effects of lateral clustering of integrins and the role of the Src family kinases. Using mobile Arg-Gly-Asp (RGD) peptide ligands on lipid bilayers with nano-...
ترکیب نانومتخلخل sba-15 دوپه شده با pd (pd-sba-15) به روش مستقیم سنتز شد. pd-sba-15 سنتزی توسط روش های طیف بینی پراش اشعه x (xrd)، میکروسکوپی الکترون روبشی (sem)، طیف بینی پراکنش انرژی (eds) و تکنیک bet مورد مطالعه قرار گرفت. ایزوترم واجذب گاز نیتروژن، اندازه تخلخل pd-sba-15 را کمتر از nm10 نشان داد. همچنین وجود pd توسط طیف بینی پراکنش انرژی تأیید گردید. به منظور مطالعه خواص الکتروکاتالیتیکیpd-...
