CuO nanoparticles were synthesized by alcohol-assisted hydrothermal method at various pH values, using sodium hydroxide as a precursor for pH control. The chemical composition, morphological and structural properties of the obtained CuO nanoparticles were investigated by the Raman and energy-dispersive X-ray spectroscopies, the field-emission scanning electron microscopy, and the X-ray diffraction.

The F2B slab model weakens the oscillations and calculations on F2B model quickly converge. However, the F2B model leads to artificial narrowness of band gap. Besides, when the number of layers increases, surface energy obtained from all three slab models approaches similar values. In particular, values of surface energy from DFT calculations converge to the experimental range for all three slab models.

This research aims to address these research gaps. Through the literature review, the most popular building PV applications in China are identified. Hence, five building PV scenarios are developed based on real-word cases, including BAPV, roof BIPV and window BIPV. Given the diverse geographic conditions and policy conditions in China, 12 typical cities are selected for the research. A MATLAB program is established to calculate energy generation and evaluate the economic performance of the building PV applications in the 12 cities.

To evaluate the effect of the single energy metal artifact reduction (SEMAR) algorithm with a multide‑ tector CT (MDCT) for knee tumor prostheses. Methods: First, a phantom of knee tumor prosthesis underwent a MDCT scan. The raw data was reconstructed by iterative reconstruction (IR) alone and IR plus SEMAR. The mean value of the CT number and the image noise were measured around the prosthesis at the stem level and articular level.

The paper conceptualizes rurbanization to bridge the gap in the research that emanates from the propensity of urban megapolises to create clutter, which results in degraded ecology, air pollution, health hazards, lower quality of life, gender inequity, and vulnerability to natural disasters. This has exacerbated during the current global pandemic. As de-covidating initiatives are unleashed, the energy access would need appropriate and manageable scale. Urbanization cannot be sustained without a robust rural interface.

We have investigated the thermodynamic properties of the cubic zirconia ZrO2 using the statistical moment method in the statistical physics. The free energy, thermal lattice expansion coefficient, specific heats at the constant volume and those at the constant pressure, CV and CP , are derived in closed analytic forms in terms of the power moments of the atomic displacements.

The ability discrimination of neutrons/gamma-rays of the detector was evaluated by the charge comparison (CC) method using an 252Cf source. The total efficiencies when measured on 22Na, 137Cs, 60Co and 252Cf sources were obtained 17.8%, 3.9%, 9.8% and 14.8%, respectively. The Figure of Merit (FoM) values of CC method were 0.4–1.55 for the range of energy 50–1000 keVee (keV electron equivalent).

The ¯uorescence resonance energy transfer parameter, f, is de®ned as the eciency of the energy transfer normalized by the quantum yield of the donor in the presence of acceptor. It is possible to characterize the ¯exibility of the protein matrix between the appropriate ¯uorescent probes by monitoring the temperature dependence of f. The intermonomer ¯exibility of the Ca-actin and Mg-actin ®laments was characterized by using this method at pH values of 6.5 and 7.4.

A computer program has been evaluated for subsite map calculations of depolymerases. The program runs inWIN-DOWSanduses the experimentallydeterminedbond cleavage frequencies (BCFs) for determination of the number of subsites, the position of the catalytic site and for calculation of subsite binding energies. The apparent free energy values were optimized by minimization of the differences of the measured and calculated BCF data.

Conformational analysis of angiotensin I (AI) and II (AII) peptides has been performed through 2D 1 H-NMRspectro-scopy in dimethylsulfoxide and 2,2,2-trifluoroethanol/H2 O. The solution structural models of AI and AII have been determined in dimethylsulfoxide using NOE distance and 3 JHNHacoupling constants. Finally, theAI family of models resulting from restrained energy minimization (REM) refinement, exhibits pairwise rmsd values for the family ensemble 0.26 ± 0.13 A ˚,1.05 ± 0.23 A ˚, for backbone and heavy atoms, respectively, and the distance penalty function is calculated at 0.

DNA-binding sites for SYCRP1, which is a regulatory protein of the cyanobacterium Synechocystissp. PCC6803, were predicted for the whole genome sequence by estimating changes in the binding free energy (DDG A total ) for SYCRP1 for those sites. The DDG A total values were calculated by summingDDGvalues derived from systematic single base-pair substitu-tion experiments (symmetrical and cooperative binding model).

For the complex parabolic Ginzburg-Landau equation, we prove that, asymptotically, vorticity evolves according to motion by mean curvature in Brakke’s weak formulation. The only assumption is a natural energy bound on the initial data. In some cases, we also prove convergence to enhanced motion in the sense of Ilmanen. Introduction In this paper we study the asymptotic analysis, as the parameter ε goes to zero, of the complex-valued parabolic Ginzburg-Landau equation for functions uε :

This is the first in a series of papers in which we initiate the study of very rough solutions to the initial value problem for the Einstein-vacuum equations expressed relative to wave coordinates. By very rough we mean solutions which cannot be constructed by the classical techniques of energy estimates and Sobolev inequalities. Following [Kl-Ro] we develop new analytic methods based on Strichartz-type inequalities which result in a gain of half a derivative relative to the classical result. ...

By very rough we mean solutions which cannot be constructed by the classical techniques of energy estimates and Sobolev inequalities. In this paper we develop the geometric analysis of the Eikonal equation for microlocalized rough Einstein metrics. This is a crucial step in the derivation of the decay estimates needed in the first paper. ...
