2017/6/24· Silicon nanowires (SiNWs) were fabried by the electroless etching of an n-type Si (100) wafer in HF/AgNO3. Vertically aligned and high-density SiNWs are formed on the Si substrates. Various shapes of SiNWs are observed, including round, rectangular, and triangular. The recorded maximum reflectance of the SiNWs is approximately 19.2%, which is much lower than that of the Si substrate …

Silicon carbide ceramic exhibits properties such as excellent thermal conductivity, low thermal expansion and excellent resistance to acid. Moreover, suitable for appliions in automotive, industrial manufacturing, and electronics & electrical they are the most corrosion resistant ceramic material.
This high-temperature treatment leads to the formation of cubic beta silicon carbide, which differs from the well-known alpha silicon carbide in certain important aspects. Not only is the crystallographic structure different (hexagonal in case of alpha versus cubic in case of Beta SiC), but also properties effected by the atomic lattice like fracture and wetting characteristics.
Experimental P-type <100> silicon wafers with an electrical resistivity of 1–10 ohm cm were used to form silicon nanowires. A metal-assisted chemical etching method was used, and AgNO 3 (99.8%), H 2 O 2 (30% in water), H 2 SO 4 98%, and HF (48%) were used as the chemical etchants. 98%, and HF (48%) were used as the chemical etchants.
Characteristics of airborne particulate matter (PM) as well as its levels in air samples collected from selected sites within cities of Dhahran, Khobar, and Dammam, in the Eastern Province of Saudi Arabia, are investigated. Concentration levels of the 10 microns’ PM (i.e., PM10) are determined using the gravimetric technique. Morphological and chemical characteristics of the
