Mixing carbon and silicon atoms to form two-dimensional (2D) silicon carbide (Si x C 1–x) sheets is promising to overcome this issue. Using first-principles calculations coined with the cluster expansion method, we perform a comprehensive study on the thermodynamic stability and electronic properties of 2D Si x C 1– x monolayers with 0 ≤ x ≤ 1.

Specimens of aluminum-based composites reinforced by silicon carbide nanoparticles (Al/SiCnp) produced by powder metallurgy (PM) were anodized under voltage control in tartaric-sulfuric acid (TSA). In this work, the influence of the amount of SiCnp on the film growth during anodizing was investigated. The current density versus time response and the morphology of the porous alumina film formed

tungsten | Uses, Properties, & Facts | Britannica
Tungsten, chemical element that is an exceptionally strong metal. Occurrence, properties, and uses The amount of tungsten in Earth’s crust is estimated to be 1.5 parts per million, or about 1.5 grams per ton of rock.China is the dominant producer of tungsten; in 2016 it produced over 80 percent of total tungsten mined, and it contained nearly two-thirds of the world’s reserves.

The wettability of silicon (Si) is one of the important parameters in the technology of surface functionalization of this material and fabriion of biosensing devices. We report on a protocol of using KrF and ArF lasers irradiating Si (001) samples immersed in a liquid environment with low nuer of pulses and operating at moderately low pulse fluences to induce Si wettability modifiion.
