Phase-transfer photolysis of metal hexacarbonyls [PDF]

Organometallics, 1992
The photochemical conversion of M(CO)6 (M = Cr, Mo, W) to M(CO)5X- (X= halogen) across a hexam/ water interface leads to a separation of the reactant and product. This process may be of general lmportence for synthetic applications. Under suitable conditions inner- filter and secondary photolysis can be avoided.

Long-lived modulation of plasmonic absorption by ballistic thermal injection

, 2020
Energy and charge transfer across metal-semiconductor interfaces are the fundamental driving forces for a broad range of applications, such as computing, energy harvesting, and photodetection. However, the exact roles and physical separation of these two

Numerical simulation of arc plasma and molten metal behavior in gas metal arc welding process

Journal of Fluid Science and Technology, 2018
In this study, to make clear the phenomena of the gas metal arc welding process more deeply, a simulation model including both the arc plasma and the metal transfer phenomena is constructed and influence of the arc current is numerically investigated ...

Transition Metal Substitution Effects on Metal-to-Polyoxometalate Charge Transfer [PDF]

Inorganic Chemistry, 2016
A series of hetero-bimetallic transition metal-substituted polyoxometalates (TMSPs) were synthesized based on the Co(II)-centered ligand [Co(II)W11O39](10-). The eight complex series, [Co(II)(M(x)OHy)W11O39]((12-x-y)-) (M(x)OHy = V(IV)O, Cr(III)(OH2), Mn(II)(OH2), Fe(III)(OH2), Co(II)(OH2), Ni(II)(OH2), Cu(II)(OH2), Zn(II)(OH2)), of which six are ...
