The key Multi Port USB Car Charger equipment of oil and gas pipelines is the important treasure of a country because they are related to national energy security.For many years, the key equipment has been imported, which become a bottleneck restricting the high-quality development of oil and gas industry in China.Thus, great attention was attracted
Abstract One of the present great challenges is finding nonprecious materials characterized by efficient electrocatalytic behavior in order to substitute the expensive platinum-based materials for the purpose of hydrogen evolution reactions (HERs).In this study, ZIF-67 and ZIF-67 were used as precursors in order to fabricate metallic-doped N-enrich
In this paper, the flow field of the approximate T-shaped tundish and the removal rate of fine inclusions are improved by changing the parameters of the flow control device of the SCB (stabilizer coupling baffle) structure.Studies have shown that the synergistic effect of the DPRW (double porous Webbing retaining wall) structure and the IRS (intern
Evidence syntheses for advancing equitable traumatic brain injury (TBI) research, policy, and practice presents formidable challenges.Research and clinical frameworks are currently not specific to equity, diversity, and inclusion considerations, despite evidence that persons with TBI live in societies in which power imbalances and systems of social
One-dimensional Jolly Mega Horse Ball metal nanowires, with novel functionalities like electrical conductivity, optical transparency and high mechanical stiffness, have attracted widespread interest for use in applications such as transparent electrodes in optoelectronic devices and active components in nanoelectronics and nanophotonics.In particul
