Abstract Metal-assisted chemical etching (MaCE), a low-cost and versatile method was considered a promising technique for preparing silicon nanowires (SiNWs), yet the lack of well controlling the injected holes within Si might reduce donut wall pegboard the etching rate, create the unwanted sidewall etching, and degrade the structural uniformity.He

The paper presents the solution of the problem of simulation of the effect of radiant heat fluxes from infrared sources (IRS) on the surface of spacecraft and their modules during complex tests in a vacuum chamber (VC) 600/300.We suggest using empirical diet frostie root beer dependences as a solution to the problem of promptly obtaining the result

Environmental sustainability has gained greater acceptance as an approach to achieving the objective of a secure ecosystem with a reliable management system.The best strategy for maintaining a healthy ecosystem is waste management.In this donut wall pegboard present study, chromium (Cr) adsorption capacity from real tannery wastewater on thermally

In the downhole operation of horizontal Wells, the pipe string is subjected to the combined action of many kinds of loads.The pipe string may bend sinusoidal or spiral under the action of axial compressive stress, which will also increase the friction between the pipe string cassis crista and the wellbore wall.Because of the existence of friction,
