Vacuum (v.83, #S1) | /a>

The measurements of atomic concentrations in amorphous hydrogenated silicon carbide (a-SiC x:H) and in amorphous hydrogenated carbon (a-C:H) were done applying the described method (results for a-SiC x:H only are presented in the paper). The possibility for high precision measurements of depth distributions of light elements is also discussed.

Annealing | TRUMPF

Some metals exhibit annealing colors when heated. The color depends strongly on the temperature to which it is heated. Annealed markings can be generated by using the laser beam to heat the workpiece to a certain temperature where the marking should appear.

At some intermediate temperature steps (800 and 1000 °C), there is a shift to the right, indiing the presence of HL‐Xe from diamond. The 1200 °C release, on the other hand, shows a very small shift toward the upper left, consistent with a small contribution from s‐process Xe carried by presolar silicon carbide (Lewis et al. 1994).

Protective Coatings on Carbon Steel - Scientific.Net

The experimental research aim was to analyze the corrosion resistance of superficial layers obtained by electrical sparking on the steel carbon samples. The electrodes used in these processes being made from corrosive resistance materials (coper and nickel). Processing by electric sparking occurs through electrode material erosion (anode) with a transfer by erosion products on the superficial

Rechargeable Na-CO2 Batteries Starting from …

Na-CO2 batteries have attracted significant attentions due to their high energy density and effective utilization of greenhouse gas CO2. However, all reported Na-CO2 batteries employ excessive preloaded metal Na, which will lead to safety issues such as dendrite formation and short circuit. In addition, the charging mechanism of reported Na-CO2 batteries is not very clear.

Ceramic - WikiVisually

A ceramic material is an inorganic, non-metallic, often crystalline oxide, nitride or carbide material. Some elements, such as carbon or silicon, may be considered ceramics.Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
