Objective of this work is to investigate the electrocatalytic efficiency using cyclic voltammetry, cathodic polarization and impedance spectroscopy techniques of the porous Ni3Al–Mo electrodes obtained by reactive synthesis of Ni, Al and Mo elemental powders. The kinetic parameters are...

The long-term stability and the effect of electrolysis on the corrosion behavior of porous Ni3Al–Mo electrode obtained by reactive synthesis of Ni, Al and Mo elemental powders for hydrogen evolution reaction (HER) were investigated in 6 M KOH solution under −100 mA cm−2 current density...

In contrast to the United States and European countries, China has witnessed a widening gender pay gap in the past two decades. Nevertheless, the size of the gender pay gap could still be underestimated as a result of not accounting for the low-wage women who have dropped out of the labor force....

Using meteorological data and mathematical statistics analysis, we take Jungar Banner in the northern farming-pastoral region of China for example, to analyze the fluctuations in the precipitation and average temperature in Jungar Banner during the period 1961-2009. We calculate the NPP value of...

Yunnan Province is the bridgehead for the opening of the southwest region in China, and the economic frontier of China-ASEAN economic cooperation, where the export of agricultural products plays an important role in promoting the openness of the southwest region and strengthening China-ASEAN...

Probability generating function (p.g.f.) is a powerful tool to study discrete compound Poisson (DCP) distribution. By applying inverse Fourier transform of p.g.f., it is convenient to numerically calculate probability density and do parameter estimation. As an application to finance and...

In order to curb anthropogenic carbon emissions and achieve the carbon intensity reduction target in China, it is crucial to shed light on influencing factors of carbon emissions at the city level. This paper selects Tianjin, one of the largest economic centers in northern China, as a study...

Based on the geological data of the Qinghai-Tibet plateau permafrost, such as the permafrost ground temperature, the thermal gradient within and below the frozen layer, we numerically investigate the gas production potential from hydrates at the DK-3 drilling site of the Qilian Mountain...

Based on the available measurement data and literature on the hydrate deposits of the South China Sea, a numerical simulation with a new dual horizontal well system has been carried out. Warm brine stimulation combined with depressurization is employed as the production method. Two horizontal...

Our proposed local vector autoregressive (LVAR) model has time-varying parameters that allow it to be safely used in both stationary and non-stationary situations. The estimation is conducted over an interval of local homogeneity where the parameters are approximately constant. The local...
