Kinetic investigations of nonlinear electrostatic excitations in quantum plasmas.

For plasmas in an extremely high-density state, like stellar cores or compressed fuel in inertial fusion facilities, their behavior turns out to be quite different when compared with those plasmas in interstellar space or magnetic confinement devices. To figure out those differences and uncover the kinetic physics in electrostatic excitations, a quantum kinetic code solving Wigner-Poisson equations has been developed. Basic plasmon decay, Landau damping, and two-stream instability of extremely high-density plasmas are investigated by using our newly developed code.

Kinetic studies of exchange-correlation effect on the collective excitations of warm dense plasmas.

The exchange-correlation of electrons, as a fundamental effect in quantum mechanics, plays an important role in the collective motions of electrons in warm dense matter. We derive the quantum kinetic equations based on the time-dependent Kohn-Sham equation. By using a temperature-dependent functional for the exchange correlation, the excitations of electrostatic waves are analyzed under the adiabatic local density approximation (ALDA).

Determinants and implications of environmental practices for waste management and the minimization in the construction industry: a case study of Pakistan.

The construction projects and activities generate waste materials, which impose negative impacts on the environment and contribute towards environmental degradation. In this regard, the implementation of environmental practices (EPs) can play a vital role in reducing the environmental risks associated with waste materials from construction projects. Based on this hypothesis, the present survey study was conducted to assess the effectiveness of different EPs in reducing environmental risks associated with waste materials from construction firms (n = 159) operating in Pakistan.

Kinetic study of quantum two-stream instability by Wigner approach.

Classical plasma are typically of low density and/or high temperature. Two of its basic properties are Landau damping and two-stream instabilities. When increasing the plasma density, quantum effects appear and beam-plasma interactions show behavior different from the classical cases.

[Gray relational analysis for the effect of nano-drug features on drug absorption].

Gray relational analysis is employed to analyze the effects of nano-drug features on phagocytosis of macrophages, including zeta potential, shape factor and scale size of drug particle, the correlation among such factors and macrophage cell is calculated. The results showed that the internalization processe is affected significantly by the zeta potential of the drug in the process of phagocytosis of macrophages, followed by the impact particle shape, and the effect of particle scale behaves relatively small.

[XPS analysis of CO2 corrosion product scales on P110 steel].

In order to confirm the composition of CO2 corrosion product scale and the difference of both component and the content between various layers of the scale, autoclave was employed to prepare the scales on P110 steel exposed to carbon dioxide corrosion. The surface and cros-section morphology were observed with scanning electron microscope (SEM), and the difference between surface and inner in chemical composition was analyzed with X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) used adjectively. The results show that the cros-section of the corrosion product scales of P110 steel is with double-layer structure, and there are mainly FeCO3 and a little of CaCO3 with ferreous oxides in two layers structure of the scale.
