Despite being applied with success in many fields of materials science, Raman spectroscopy is not yet determinant in the study of electroceramics. Recent experimental and theoretical developments, however, should increase the popularity of Raman spectros
Another benefit of titanium for eyewear is that titanium is hypoallergenic, which means that -unlike many metals containing nickel- it will not cause skin irritation.Three types of titanium are widely used in eyewear frames: commercially pure, Beta, and memory metal. The first titanium eyewear ...
Supported metal nanoparticles, M-NPs, are of great scientific and economic interest as they encompass application in chemical manufacturing, oil refining and environmental catalysis. Oxidation and hydrogenation reactions are among the major reactions catalyzed by supported M-NPs. Although supported M-NPs ...
Copper and copper alloys are used to produce sintered metals. Sintered steel is produced using steel and steel alloys. Powder iron can be used to produce sintered iron. Tantalum and tungsten are metals with such high melting points that sintering is one of the few options that can be used fo...
The synergistic effect in Pt2W/WO3 can effectively lower the adsorption energy of hydrogen on the catalyst surface to make the hydrogen adsorption Gibbs free energy (ΔGH∗) approach the ideal value of zero. Moreover, durability, one of the key factors for electrocatalytic reactions, can ...
The three most significant are: atomization of prealloys, diffusion bonding by annealing, and binder treatment of premixes. The VINNAPAS® grades B 100, UW 1 and UW 4 are highly recommended for use as binder in these formulations. Our products combine the following properties: • Outstanding...
The presence of ferroelectric material as a component of a heterostructure along with a heavy metal such as Bi may enhance splitting thanks to ferroelectric polarization. In addition, the external electric field may increase the internal electrostatic field and slightly increase the splitting. The chang...
