In this study, the p-type Ga-doped Cu3Sb1−xGaxSe4 compounds were fabricated by melting, annealing, grinding, and spark plasma sintering (SPS). The transport properties of Ga-doped Cu3Sb1−xGaxSe4 compounds were investigated. As Ga content increased, the hole concentration of Cu3Sb1−xGaxSe4 compounds increased, which led to an increase in electrical conductivity. Meanwhile, the Seebeck coefficien...

Room-temperature welding with gallium is regarded as a new strategy because of the low melting point and its affinity for forming intermetallic compounds other metals. Benefitting from liquid gallium-based solder an ultrasonic drive, establishment Cu/Cu diffusion-bond connections can be quickly completed. The underlying characteristics weld quality room-temperature bonding were preliminarily cl...

Gallium nitrate is active against lymphoma and bladder cancer; however, little is understood about tumor resistance to this drug. Transferrin, the iron transport protein, increases gallium uptake by cells, whereas pyridoxal isonicotinoyl hydrazone (PIH), an iron chelator, transports iron into cells. Therefore, we examined whether these metal transporters would increase the cytotoxicity of galli...

Invasive pulmonary aspergillosis (IPA) is a life-threatening form of fungal infection, primarily in immunocompromised patients and associated with significant mortality. Diagnostic procedures are often invasive and/or time consuming existing antifungals can be constrained by dose-limiting toxicity drug interaction. In this study, we modified triacetylfusarinine C (TAFC), the main siderophore pr...

Nitride semiconductors are attractive because they can be environmentally benign, comprised of abundant elements and possess favourable electronic properties. However, those currently commercialized are mostly limited to gallium nitride and its alloys, despite the rich composition space of nitrides. Here we report the screening of ternary zinc nitride semiconductors using first-principles calcu...

Cobalt sulfate hydrate, gallium arsenide, molybdenum trioxide, vanadium pentoxide, and nickel sulfate heptahydrate were tested in the Syrian hamster embryo (SHE) assay in order to increase the SHE assay database for heavy metals. All five compounds produced significant morphological transformation at one or more doses in a dose-responsive manner. Cobalt sulfate hydrate, gallium arsenide, molybd...

A procedure has been developed for synthesis of 2-alkenyl-2H-indazoles starting from 2-(2-carbonylmethyl)-2H-indazoles, which are prepared by gallium/aluminium- and aluminium-mediated, direct, regioselective alkylation of indazoles with α-bromocarbonyl compounds. The structure of 3-(2H-indazol-2-yl)-2H-chromen-2-one was proven by X-ray crystallography. The styrene- and coumarin-2H-indazoles pro...

Gallium, a pharmacologically important metal, resembles iron with respect to transferrin (Tf) binding and Tf receptor-mediated cellular uptake. In the present study, we examined the effect of gallium on Tf-independent iron uptake by HL60 cells. In contrast to the inhibitory effect of Tf-gallium on Tf-iron uptake, gallium nitrate, in a time-, temperature-, and concentration-dependent manner, sti...

The gallium(III) complex of orotic acid (HOA) was synthesized and its structure was determined by means of analytical and spectral analyses. Detailed vibrational analysis of HOA, sodium salt of HOA (NaOA) and Ga(III)-OA systems based on both the calculated and experimental spectra confi rmed the suggested metal-ligand binding mode. Signifi cant differences in the IR and Raman spectra of the com...
