Hace 4 días · By choosing forming gas (N2/H2) during thermal annealing of carbon-implanted silicon, we can select the formation of a series of hydrogen and carbon-related quantum emitters, ...
Hace 3 días · Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively ...
Hace 5 días · We hypothesize that the ionization of silicic acid can promote Si assimilation in the rhizosphere, improving plant vigor, CCS, and stress tolerance [162], [163]. Si amendments, such as silicate rock, can potentially reduce global warming by reducing CO 2 emissions and increasing carbon sequestration in the soil.
Hace 1 día · Silicon (Si) has been widely investigated as anodes of lithium-ion batteries (LIBs) due to its high theoretical capacity. However, the huge volume expansion and low electrical conductivity limit its practical application to some extent. Here, we prepared a composite structure in which the ammonia-modified Si
Hace 2 días · Five nonmetallic elements—hydrogen, carbon, nitrogen, oxygen, and silicon—make up the bulk of Earth's oceans, atmosphere, biosphere, and crust. The diverse properties of nonmetals enable a range of natural and technological uses.
Hace 6 días · The composite consists of multiwall carbon nanotubes and a ceramic made of silicon, carbon and nitrogen. Including boron boosts the breakdown temperature. The nanotubes and graphene-like carbon transmit heat well, while the oxidation-resistant ceramic boosts damage resistance.
Hace 8 horas · This study examines silicon and CNT (Si-CNT) composite, synthesized by a simple and easy method, for supercapacitor applications. The supercapacitor electrodes active material was a composite of Si and CNT. It was made by magnetic stirring, mixing, ultrasonication, vacuum filtration, and drying process of the powdered Si and CNT with a binder.
