ABSTRACT. The reaction between benzil and hexamethylenediamine formed a new ligand [L], [(1Z,3Z)-2,3-diphenyl-5,6,7,8,9,10-hexahydro-1,4-diazecine], of the type [N2], was synthesized by condensation through Schiff base hexamethylenediamine. reacts with Mnп, Niп Coп metal ions to give complexes general formula: [M(L)Cl2]. elemental investigations have been used analyze its CHN, FT-IR, UV-Vis, TL...

Photoinduced phase transitions in organic compounds with strong electron correlation ET [bis(ethylenedithio)-tetrathiafulvalene)-based salts α-(ET)2I3, θ-(ET)2RbZn(SCN)4, κ-(d-ET)2Cu[N(CN)2Br] were discussed based, on time resolved optical pump-probe spectroscopy using ~150 fs mid-infrared pulse, 12 fs near infrared pulse, and sub-picosecond terahertz pulse. (i) In charge-ordered insulators α-(...

With the development of modern industry, sheet-metal parts in mass production have been widely applied in mechanical, communication, electronics, and light industries in recent decades; but the advances in sheet-metal part design and manufacturing remain too slow compared with the increasing importance of sheet-metal parts in modern industry. This paper proposes a method for automatically extra...

In section many low-FeO CR chondrules are surrounded by rings of metal; this metal-cladding seems to have formed during chondrule melting events as films of metal that wetted the surface. Electron microprobe studies show that in each ring the metal is very uniform in composition, consistent with efficient mixing during formation of the metal film. In contrast the mean Ni contents of 13 differen...

The thiosemicarbazone of 9-anthraldehyde, (9-ATSC) and its group 12 metal complexes have been synthesized. The compounds have been characterized by IR, electronic and NMR spectrometries, molar conductivity, melting points and elemental analysis. In all the complexes, the 9-ATSC coordinates through the sulfur and the azomethinic nitrogen. The zinc (II) complex shows a 1:2 metal to ligand stoichi...

Recent decades seen the success of Additive Manufacturing (AM) in many industrial applications including aerospace, biomedical, automotive, and tooling. In manufacturing metallic parts, AM technology has ability to produce parts with complex geometries which are difficult or impossible using conventional fabrication methods, such as machining casting. Another benefit is employment metal alloys ...

We demonstrate a process to selective laser melt metal alloy directly onto graphite. The heat transfer applications of features printed annealed pyrolytic graphite are compelling, as has the second highest in-plane thermal conductivity (>1500 W/m-K at room temperature) any bulk material. While bonding alloys commonly used in melting (SLM) with is relatively weak, proper interlayer material dras...

induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. the wide application is based on good efficiency, high production rate and non-polluting conditions. for designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output...
