Unlike fossil fuels,hydrogen is a renewable and clean energy source.It is available in a large amount and spreads throughout the world.When reacting with oxygen,hydrogen releases energy to produce water as the only product.Hence,hydrogen is a promising alternative to fossil fuels [1].Today,most of hydrogen is produced via the steam methane reforming process,in which high-temperature steam is used to produce hydrogen from a methane source.However,methane is non-renewable,and carbon dioxide is generated in the reforming process.The development of clean,sustainable,and cost-competitive hydrogen production processes is essential to promote the practical application of hydrogen as an energy source.

The effective notch stress approach for evaluating the fatigue strength of rib-leck welds requires notch stress concentration factors obtained from complex finite element analysis.To improve the efficiency of the approach,the notch stress concentration fa
In this paper,a half-plane time-domain boundary element method is applied to obtain the seismic ground response,including a subsurface box-shaped lined tunnel deployed in a linear homogenous elastic medium exposed to obliquely incident SH-waves.Only the b
The general discrete scheme of time-varying Reynolds equation loses the information of the previous step,which makes it unreasonable.A discretization formula of the Reynolds equation,which is based on the Crank-Nicolson method,is proposed considering the
