The tunable wettability by pH‐stimulus has great potential in liquid adhesion, transport, collection, and separation due to its rapid response and wide control range. However, achieving pH‐regulated wettability on the selected region of material without acid–base contamination presents a distinct challenge for the existing methods. Here, a scalable conductive network membrane is prepared with switchable...
Oil–water separation membranes easily fail to oil foulants with low surface energy and high viscosity, which severely limits these membranes’ applications in treating oily wastewater. Herein, an oil–water separation membrane by bioinspired bubble‐mediated antifouling strategy is fabricated via growing hierarchical cobalt phosphide arrays on stainless steel mesh. The as‐prepared membrane is superhydrophilic/superaerophobic...
Mankind's energy problems are the biggest problems of human existence and development. Human energy has gone through three times, the use of firewood energy that the fire started is a sign of human civilization, as an era has ended, As an era has ended, the chemical energy of modern civilization and contribute to the development of productive forces, the side effects are also evident, Humans gradually...
The experimental results showed that the layer is composed of boride zones and transition zones. Boride zones are dense and there are not porosities and micro-crack. The boride zones of carbon steel appear tine-comb by low-temperature boronitriding and consist FeB+Fe2B. The boride zones of alloyed steel appear flat, and their phase constitution are compLicated. The phase constitution of the surface...
In this paper, we study, for the first time, the effect on multiple-input multiple-output (MIMO) wireless communications system performance of recently measured statistical relationships among the azimuth spread at the base station (ASb), the azimuth spread at the mobile station (ASm), and the Rician K-factor. We construct a 4 × 4 MIMO channel model with lognormally-distributed and correlated ASb,...
