TL;DR: In this paper, metal microclusters of lead, indium, bismuth and antimony in the size range between 2 to 500 atoms per cluster are generated by inert gas condensation, extracted into vacuum and detected by mass spectrometry.
Abstract: Metal microclusters of lead, indium, bismuth and antimony in the size range between 2 to 500 atoms per cluster are generated by inert gas condensation, extracted into vacuum and detected by mass spectrometry. Resolved clusterpeaks are observed up to Pb110, In50, Bi70 and Sb240. Condensation conditions, beam intensities and limitations of the cluster source are discussed.

TL;DR: In this article, spray pyrolised CuSbS2 thin films were synthesized and characterized using X-ray diffraction, Raman spectroscopy, Xray photoelectron spectrography, atomic force microscopy, UV-visible spectrograms, and Hall effect measurements.
Abstract: Copper antimony sulfide (CuSbS2) thin films have been gained interest recently as an emerging light absorbing material for photovoltaic applications. In this work we report synthesis and characterization of spray pyrolised CuSbS2 thin films. The precursor solution consisted of SbCl3, CuCl2 and NH2CSNH2 dissolved ethanol. The substrate temperature was kept at 200 °C. Samples were prepared at different molar ratios of Cu:Sb:S. These thin films were characterized using X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, atomic force microscopy, UV-visible spectroscopy, photocurrent and Hall effect measurements. P-type CuSbS2 thin films of orthorhombic structure were formed and the films showed photocurrent response. (© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

TL;DR: In this paper, an atomic-absorption spectrophotometric method for the rapid and sensitive determination of arsenic, antimony, and selenium with the hydride-argon/hydrogen flame system has been studied.
Abstract: An atomic-absorption spectrophotometric method for the rapid and sensitive determination of arsenic, antimony, and selenium with the hydride-argon/hydrogen flame system has been studied. The comparison of the zinc tablet combined with stannous chloride and potassium iodide, and the sodium borohydride tablet reduction systems are described. The sensitivities and precisions of both reduction systems are estimated to be nearly the same. From the results of the comprehensive study on interferences, the zinc system is concluded to be more selective than the sodium borohydride system, which is especially true for arsenic.

TL;DR: In this article, the authors presented data for the hydride generation atomic absorption spectrometric determination of arsenic, antimony, bismuth and selenium in stream sediments and a certified reference material.
Abstract: Data are presented for the hydride generation atomic absorption spectrometric determination of arsenic, antimony, bismuth and selenium in stream sediments and a certified reference material (CPB-1 Lead Concentrate) using six different extraction media, viz., hydrochloric acid; nitric acid; 7 M nitric acid; nitric acidsulphuric acid (9 + 1); aqua regia; and reversed aqua regia (HNO3+ HCl, 3 + 1). Extraction with 7 M nitric acid was performed in test-tubes placed in a drilled out heating block (110 °C, 3.5 h). All other extractions were carried out overnight in 50-ml calibrated flasks placed in a water-bath. Bismuth was extracted quantitatively by all the extraction media. Arsenic and selenium were extracted completely by each of the media used, except for hydrochloric acid. Antimony was extracted completely by only two of the media, viz., aqua regia and reversed aqua regia. Selenium is converted to the +4 oxidation state on extraction with aqua regia and reversed aqua regia, i.e., selenium(VI) is reduced to selenium(IV), and the lower oxidation states are oxidised to selenium(IV). Hence the extracts can be analysed for selenium without pre-reduction to selenium(IV), which is necessary for hydride generation atomic absorption spectrometry. The nitric acid-hydrochloric acid mixtures used bring arsenic, antimony, bismuth and selenium quantitatively into solution and are, therefore, suitable for the sequential or simultaneous determination of these elements in a single sample solution. The speciation of selenium in stream sediments and surface waters is discussed.
