The high current and ESD effects on VLSI interconnect metallization have been characterized and a model for heating under ESD conditions is presented. I t is shown that thermal breakdown occurs when the resistances increase by a factor of >3.6 due to melting of metal lines. After the metal is molten, the thermal stress is required to exceed the fracture strength of the oxidelnitride layers in o...

We report two cases of severe thermal burns on the ocular surface and its adnexal appendages that developed secondary to exposure to molten heavy metal with a melting temperature of near-thousand degree Celsius. Despite aggressive intervention and strict monitoring, the profound inflammation caused significant damage to the ocular surface, ending up in an intractable infection with an unfavorab...

A series of transition metal complexes of the ligand 5-bromo salicylaldehyde-2-furoic acid hydrazide have been prepared using Ti(III), Mn(III), V(III), Co(III), Fe(III), Ru(III) and Rh(III). The complexes have been characterized by elemental analyses, melting points, molar conductance, magnetic susceptibility measurement, electronic and infra red spectral studies. Based on these studies octahed...

One-step direct nanoimprinting of metal nanoparticles was investigated to fabricate nano-/microscale metallic structures such as nanodot and nanowire arrays. This was done at low temperatures and pressures, utilizing the low melting temperature and viscosity of metal nanoparticle solutions. Through precise control of the fluidic properties of the nanoparticle solution and the mold design, high-...

Present paper reports an overview on the processing, corrosion behavior and applications of various metal matrix composites with a special focus on iron based metal matrix nanocomposites. As iron has a much higher melting temperature compared to aluminum, copper and magnesium therefore it is synthesized using powder metallurgy technique. P/M technique is widely used because it provides microstr...

Introduction: Ureilites are ultramafic, igneous achondrites, which contain olivine (ol), pyroxene, metal and carbon. About ~10 vol% dark interstitial, fine-grained matter is usually referred as vein material [1]. Ureilites have lost ~25% basalt [2] and most of their metallic iron. Presently, many authors assume that the majority of ureilites formed as asteroidal melting residues [3, 4]. Althoug...

abstractthe ability of hesperidin (hp) to form complexes with five metals; cobalt, nickel, zinc, calcium and magnesium was investigated. the complexation was studied using u.v spectroscopic titration, in methanol as well as aqueous buffer solutions (physiological conditions). potential complexes were studied by ir and nmr spectroscopy, melting point and their solubility were also evaluated. the...

Abstract: This study presents the research results of effect that refining process has on porosity and mechanical properties of high pressure die castings made of AlSi12S alloy. The operation of refining was carried out in a melting furnace with the use of an FDU Mini Degasser. Mechanical properties (UTS, YS, Elongation, Brinell Hardness) were assessed on samples taken from high pressure die ca...
