Special requirements are imposed on light-absorbing coatings on products made of aluminum and titanium alloys: ensuring a given spectral reflection coefficient and brightness coefficient; ensuring mechanical strength, hardness and resistance to environmental influences, high adhesion of the coating to the base. In some cases, the coating also requires high resistance to ultraviolet ...

The object of the study is the Skybridge Michigan suspension bridge, the construction of which was completed in October 2022. The article provides information about the installation of a cable system.

Alumina production will produce a large amount of red mud wastewater every year, which will cause great harm to the surrounding environment. In this study, a solar evaporator using biochar as photothermal material for red mud wastewater treatment was designed. Driven by sunlight, the device can recover water from red mud wastewater and absorb harmful substances in wastewater. ...

The comparative analysis of Al2O3 coatings and effect of surface morphology on the wettability properties were discussed. It was shown that it is possible to obtain high hydrophilic parameters with a contact angle value up to 17–20° using high values of current density, anodizing time, and electrolyte temperature by adjusting the electrochemical conditions. It was seen that this ...

In this article there is a completed description of a calculation of a reinforced concrete construction with finite element modeling located in soil. The calculation was carried out on an electronic computer complex using software. Physical and mechanical properties of soil and reinforced concrete construction were taken into account.

Valuable elements in lithium-ion batteries is a very significant secondary resource. Based on the recovery and recycling of the spent all-solid-state lithium-ion batteries in the future, we explore extracting valuable lanthanum, zirconium, and lithium elements from the solid electrolyte tetragonal phase LLZO by the leaching with the dilute sulfuric, and then by precipitation ...

ZnO nanowires with semi-polar and non-polar orientations are fabricated on Si (100) substrates by low temperature chemical solution deposition. This distinctive growth is achieved by a co-effect of the seed layer templates and CBD solution. The growth mechanism is illustrated in detail and these semi-polar and non-polar ZnO/Si heterostructures show an excellent unidirectional ...

Now, there are 36 million km2 of deserts on the planet, a quarter of the land area, and expanding by 60,000 km2 per year. To combat climate change and achieve the carbon peaking and carbon neutrality goals, China is engaged in afforestation. However, water scarcity, strong winds and shortcomings of current irrigation methods make afforestation a major challenge. Based on the ...

Ferrite absorbing metamaterials designed with metamaterial structures can effectively broaden the absorption bandwidth of electromagnetic waves. The current mainstream approach is to compound ferrite with other materials to produce ferrite absorbing metamaterials with better performance.

Garbage enzymes rationally using of waste from fruits and vegetables are rich in nutritionally active substances and microbial groups and positively affect the growth of agricultural crops. In this project, by studying the effect of different classes of garbage enzymes on plant growth at different concentrations, and study on molecular biological mechanism will provide sufficient ...
