TL;DR: In this paper, a two-dimensional antimony sulfide was synthesized under hydrothermal conditions in the presence of N,N'-bis(3-aminopropyl)ethylenediamine and characterized by single-crystal X-ray diffraction, thermogravimetry and elemental analysis.
Abstract: A new two-dimensional antimony sulfide has been synthesized under hydrothermal conditions in the presence of N,N‘-bis(3-aminopropyl)ethylenediamine and characterized by single-crystal X-ray diffraction, thermogravimetry and elemental analysis. The product [C8N4H26]0.5[Sb7S11] (Mr = 1294.07) crystallizes in the triclinic space group, P1, with a = 5.9550(3) A, b = 14.567(1) A, c = 15.093(1) A, α = 68.448(4)°, β = 86.044(6)°, γ = 82.280(6)°, V = 1206 A3, and Z = 2. The structure consists of infinite chains of formula Sb7S112- linked through antimony−antimony bonds (2.921(2) A) into two-dimensional slabs of approximate thickness 2.6 A. These slabs contain pores of dimensions ca. 17.5 × 5.2 A, which are aligned along the [100] direction. N,N‘-Bis(3-aminopropyl)ethylenediamine cations reside between the slabs to which they are hydrogen bonded.

TL;DR: It was found that addition of this particular surfactant significantly improved the microstructural properties as well as homogeneity of the films with a significant improvement in the thermoelectric properties over those deposited in the absence of Surfactant.
Abstract: High-quality films of bismuth antimony telluride were synthesized by electrodeposition from nitric acid electroplating baths. The influence of a surfactant, sodium ligninsulfonate, on the structure, morphology, stoichiometry, and homogeneity of the deposited films has been investigated. It was found that addition of this particular surfactant significantly improved the microstructural properties as well as homogeneity of the films with a significant improvement in the thermoelectric properties over those deposited in the absence of surfactant. A detailed microprobe analysis of the deposited films yielded a stoichiometric composition of Bi0.35Sb1.33Te3 for the films electrodeposited in the absence of surfactant and a stoichiometry of Bi0.32Sb1.33Te3 for films deposited in the presence of surfactant.

TL;DR: In this paper, a new method was developed for simultaneous determination of trace arsenic and antimony in Chinese herbal medicines by hydride generation-double channel atomic fluorescence spectrometry with a Soxhlet extraction system and an n -octanol-water extraction system, respectively.
