Gallium was discovered using spectroscopy by French chemist Paul Emile Lecoq de Boisbaudran in 1875 from its characteristic spectrum (two violet lines) in a sample of sphalerite.[45] Later that year, Lecoq obtained the free metal by electrolysis of the hydroxide in potassium hydroxide solution.[...
The discovery of gallium filled a spot predicted by Mendeleev's periodic table. Gallium took the place of the placeholder element eka-aluminum. Gallium was first identifiedusing spectroscopyby its distinct pair of violet spectral lines. Gallium's melting point (302.93 K) is low enough to melt th...
Nuclear Magnetic Resonance Spectroscopy in Liquids containing Compounds of Aluminium and GalliumIn the last few years, there has been the discovery and characterization of a number of complexes of aluminium and of gallium, by nuclear magnetic resonance (NMR). The solvation complexes are reported with...
Credit for the discovery of gallium in 1875 is given to Paul-Emile Lecoq de Boisbaudran who noted its presence as two distinct bands on spectroscopy. Gallium is a group IIIA metal, atomic number 31 that exists in the earth's crust at a concentration of 5–15 mg/kg and is obtained as...

Following incubation, 50 μL of ice-cold 10% trichloroacetic acid was added to each well and the well contents harvested onto glass fiber filters and assessed for3H-TTP incorporation by β-scintillation spectroscopy17,38. HIV-1p24 antigen immunostaining HIV-1p24 antigen staining was determined ...
operando diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) of CO2hydrogenation was performed. DRIFTS results indicate that carboxylate, carbonate, and methyl species are detected at the initial stage of the reaction (Supplementary Fig.11and Supplementary Table6). The bands assigned to ...
Deep level transient spectroscopy (DLTS)Meyer–Neldel ruleBy using thermal electron emission data from the literature in addition to own measured results for totally 40 data sets of deep level centers in GaAs, we demonstrate that they can be divided into two different classes. We find that all ...
They are also relevant to the recent direct observation of the conduction band dispersion in GaN0.0008As0.9992 QWs using magnetotunnelling spectroscopy [26], and provide further insight into the low mobility values generally observed in Ga(In)xAs1-x alloys [2,27,28]. It is well established ...
The morphology and elemental mappings of the ashes derived from the simulated combustion at various temperatures were characterized by an MIRA LMS scanning electron microscopy and energy dispersive spectroscopy (SEM-EDS, TESCAN Group, Brno, Czech Republic). The concentrations of Li and Ga in the ...
