ZnO films prepared at different temperatures and annealed 900°C in oxygen are studied by photoluminescence (PL) x-ray photoelectron spectroscopy (XPS). It is observed that the PL of as-grown green luminescence (GL) yellow (YL) related, after annealing GL restrained YL enhanced. The O 1s XPS results also show coexistence vacancy (VO) interstitial (Oi) before quenching VO annealing. By combining two it deduced related to Oi defects, respectively.
Injectable self-healing hydrogels containing functional nanoparticles (NPs) have attracted much attention in many fields of biomedicine. A series injectable PEGylation CuS NPs based on N-carboxyethyl chitosan (CEC) and oxidized sodium alginate (OA) were developed by taking advantages the unique functions chitosan, referred to as NP or CEC–OAm–CuSn, where "m" stands for concentration percentage added OA solution (w/v) "n" represents molar hydrogels. The physical properties hydrogels,...
Experimental investigations were conducted on a NACA0012 airfoil to determine the influences of mounting angles and locations lift-enhancing effects Gurney flaps at Reynolds number 2.1 x 10 6 . The results revealed that all different increased lift coefficient, an increment maximum coefficient 12.3, 15.1, 17.4% was obtained by 45-, 60-, 90-deg flap, respectively. There drag penalty associated with enhancement. best performance 45-deg flap for deflections tested. When shifted forward from...
CO2 switchable foams have gained increasing attention recently for their smart properties. However, performance at high temperature and pressure has been less documented. In this study, a long-chain viscoelastic surfactant, N1-(3-aminopropyl)-N3-octadecylpropane-1,3-diamine bicarbonate (ODPTA) studied as foam agent its application in flooding complex harsh reservoir conditions, the under static dynamic conditions was tested up to 160 °C 10.5 MPa using visualized foam-meter sand-pack...
To study the pattern of formation water evaporation and salt precipitation, based on oil-gas-water three phase thermodynamic equilibrium, principle dissolution/precipitation, results precipitation experiment, a comprehensive model considering evaporation, NaCl in water, reservoir porosity permeability variations was established to analyze its influence factors during development high temperature gas reservoir, some methods preventing removing were proposed. The show that usually occurs...
The valence band offset (VBO) of the wurtzite InN∕ZnO heterojunction is directly determined by x-ray photoelectron spectroscopy to be 0.82±0.23eV. conduction deduced from known VBO value 1.85∓0.23eV, which indicates a type-I alignment for heterojunction.
Flexible and transparent anti-counterfeiting films have aroused great attention for their potential applications in information security assurance of product quality recently. Much has been focused on the crystalline structure matrix; however, studies amorphous alumina hosts are limited. Here, an doped with Eu3+ phosphor was successfully synthesized by a soft chemical route. Its evolution, morphology, photoluminescence features were analyzed. The host offers free access simultaneously avoids...
Using copper sulfide nanoparticles as cross-linkers of tumor microenvironment responsive polymer micelles for cancer synergistic photo-chemotherapy presents promising therapeutic effects in treatment.
The temperature dependence of the formation nano-scale indium clusters in InAlGaN quaternary alloys, which are grown by metalorganic chemical vapour deposition on GaN/Si(111) epilayers, is investigated. Firm evidence provided to support existence phase separation, or In-rich clusters, combined results high-resolution transmission electron microscopy (HRTEM), x-ray diffraction (HRXRD) and micro-Raman spectra. HRXRD Raman spectra indicate that degree separation strong number In layers silicon...
