TL;DR: In this paper, a multifunctional uniform antimony (Sb) nanoarrays are designed and grown on Ti3C2Tx MXene paper and shown that antimony can reversibly alloy with Zn to form ZnSb phase, which enable antimony as both alloying-type Zn storage material and zincophilic nucleation seed to regulate homogeneous Zn deposition.

TL;DR: In this paper, XPS and AES have been applied to the surface analysis of antimony oxides, Sb2O3 and Sb 2O4, by means of computer-operated separation of oxygen and antimony contribution, the oxygen to metal atomic ratios calculated from XPS data were found to be close to the expected values.
Abstract: XPS and AES have been applied to the surface analysis of antimony oxides, Sb2O3, Sb2O4 and Sb2O5. By means of the computer-operated separation of oxygen and antimony contribution, the oxygen to metal atomic ratios calculated from XPS data were found to be close to the expected values. An antimony powder sample was found to be covered by a surface layer of Sb2O4 and the variations in shape of Auger MNN peaks of Sb during depth profiling are shown and discussed.

TL;DR: In this article, a technique for the determination of "inorganic" arsenic(III), "methylarsenic" and "dimethylarsenic", species is described which is based on the trapping of arsines and selective volatilisation into a heated quartz atomiser tube situated in the optical path of an atomic-absorption spectrometer.
Abstract: A technique for the determination of “inorganic” arsenic(III) and arsenic(V), “methylarsenic” and “dimethylarsenic” species is described which is based on the trapping of arsines and selective volatilisation into a heated quartz atomiser tube situated in the optical path of an atomic-absorption spectrometer. Improved reproducibility is obtained by the use of a continuous flow reduction stage and detection limits are approximately 0.25 ng (based on twice the standard deviation of 10 blank measurements). For a typical sample volume of 10 ml this corresponds to a detection limit of 0.025 ng ml–1 of arsenic. Interferences were investigated and depression of results was observed in the presence of silver(I), gold(III), chromium(VI), iron(II), iron(III), germanium(IV), molybdenum(VI), antimony(III), antimony(V), tin(II), manganese(VII) and nitrite. Various approaches to overcoming such interferences were investigated, and for general use masking with EDTA is advocated. The choice of extraction procedures for speciation analysis is discussed.

TL;DR: This work synthesizes the first antimony(III) borate in closed system, namely SbB 3 O 6, which not only exhibits an exceptional linear optical response, but also has a strong nonlinear optical response that exceeds those of most borates.
Abstract: Antimony(III) borates with a stereochemical active lone pair remained unknown, although the first antimony borate was reported more than twenty years ago. Now, the first antimony(III) borate in a closed system is successfully synthesized, namely SbB3 O6 . Remarkably, SbB3 O6 not only exhibits an exceptional linear optical response, that is, birefringence of Δn=0.290 at the wavelength of 546 nm, which is the largest among borates, but also has a strong nonlinear optical response of 3.5 times larger than the benchmark KH2 PO4 , exceeding those of most borates. Theoretical calculations reveal that the coexistence of strong linear and nonlinear optical responses in SbB3 O6 should be attributable to the synergistic effect of π-conjugated B-O anionic groups and Sb3+ with stereochemically active lone pair. This work provides a new class of optical bi-functional materials with potential prospects in integrated optical devices.
