3An“endocrine function of”bone to pick:starting with males显示文摘A stereotypical presentation of a hero in a Hollywood action movie would lavishly brag about not only strong muscle but also a large statue(a.k.a.bone structure),ostensibly for an attractive image.Unknown to these movie producers is that the bone tissue does send a“sex-related”message,an endocrine message to be exact,to the male reproductive system.Maybe we shouldn’t blame Hollywood for their naivetéafter all;even in the scientific community,there is a long-held traditional belief that regards skeletal bone as merely a structural and supportive tissue.However,this view has been challenged by a series of recent studies.Allan Z.Zhao Dongming Su 2011Protein & Cell2011,2,3:1
4A portable X-pinch design for x-ray diagnostics of warm dense matter显示文摘We describe the design and x-ray emission properties(temporal,spatial,and spectral)of Dry Pinch I,a portable X-pinch driver developed at Imperial College London.Dry Pinch I is a direct capacitor discharge device,30033003700 mm3 in size and∼50 kg in mass,that can be used as an external driver for x-ray diagnostics in high-energy-density physics experiments.Among key findings,the device is shown to reliably produce 1.1±0.3 ns long x-ray bursts that couple∼50 mJ of energy into photon energies from 1 to 10 keV.The average shot-to-shot jitter of these bursts is found to be 10±4.6 ns using a combination of x-ray and current diagnostics.The spatial extent of the x-ray hot spot from which the radiation emanates agrees with previously published results for X-pinches-suggesting a spot size of 10±6μm in the soft energy region(1–10 keV)and 190±100μm in the hard energy region(>10 keV).These characteristics mean that Dry Pinch I is ideally suited for use as a probe in experiments driven in the laboratory or at external facilities when more conventional sources of probing radiation are not available.At the same time,this is also the first detailed investigation of an X-pinch operating reliably at current rise rates of less than 1 kA/ns.J.Strucka J.W.D.Halliday T.Gheorghiu H.Horton B.Krawczyk P.Moloney S.Parker G.Rowland N.Schwartz S.Stanislaus S.Theocharous C.Wilson Z.Zhao T.A.Shelkovenko S.A.Pikuz S.N.Bland 2022Matter and Radiation at Extremes2022,7,1:0
5Surface modification of tungsten oxide by oxygen vacancies for hydrogen adsorption显示文摘A model for describing the adsorption process of hydrogen on surface of tungsten oxide was proposed based on the first-principle calculations. Multiple factors such as type of active surface, adsorption site and distribution of oxygen vacancies were considered to evaluate the hydrogen adsorption capability of tungsten oxide. The adsorption Gibbs free energies, electronic structures and bonding characteristics under various conditions were examined to reveal the influence of oxygen vacancies on the surface. It is found that the capability of hydrogen adsorption of tungsten oxide can be significantly enhanced by adjusting the oxygen vacancy on the outermost layer of certain active surfaces. The modeling predicts that the surface structure stability and gas adsorption ability of tungsten oxide can be simultaneously improved through the formation of W–H bonds. The proposed strategy for moderating surface provides a new approach to obtain excellent gas-sensitive metal oxide materials.Q.Zhang F.W.Tang Z.Zhao Z.R.Nie X.Y.Song 2022Journal of Materials Science & Technology2022,,22:0
