Inspired by the naturally occurring fluorescent mineral, ferroan sphalerite, [(Fe,Zn)S] nanoparticles were synthesized by a three component reaction of [Fe(Mes)2]2 (Mes = mesityl or C6H2Me3-2,4,6), [Zn(Et)(ONep)(py)]2, and elemental S via both soluti

A series of alkaline earth modified titanium neo-pentoxide (OCH2CMe3, ONep) derivatives were synthesized through the alcoholysis reaction of [Ti(μ-ONep)(ONep)3]2 and the respective alkaline earth alkoxide (AE(OR)2), where AE(OR)2 = “Ca(ONep)2” (

Under conditions that were predicted as "safe" by well-established TCAD packages, radiation hardness can still be significantly degraded by a few lucky arsenic ions reaching the gate oxide during self-aligned CMOS source/drain ion implantation. The m

We have synthesized a variety of structurally diverse “Zn(OR)(Et)(solv)” and “Zn(OR)2(solv)2” where Et = CH2CH3 and solv = no bound solvent, pyridine (py), tetrahydrofuran (THF), or 1-methyl imidazole (MeIm). The ligand OR represents the foll

A study was conducted to understand the wetting phenomena observed in brazing of a Ti-containing active filler metal on sapphire substrates. The goal of the study was to understand the interfacial reactions that permit wetting of commercial Ag-Cu-Ti

An anhydrous route for the synthesis of amine-capped coinage-metal nanoparticles (NP) has been developed using coinage-metal mesityl (mesityl = 2,4,6-Me3C6H2) derivatives. Under an argon atmosphere, crystalline [Cu(μ-mesityl)]5, [Ag(μ-mesityl)]4, a

A new crystallographic orientation relationship (OR) between delta-ferrite and austenite has been observed in solidification microstructures of 304L and 309S austenitic stainless steels and a ternary Fe-Cr-Ni alloy. Evidence for the new OR was obtain

Hydrogen was ion-implanted into wurtzite-phase GaN, and its transport, bound states, and microstructural effects during annealing up to 980°C were investigated by nuclear-reaction profiling, ion-channeling analysis, transmission electron microscopy,
