“…The application prospect of a CO 2 stimulation responsive SFME is very wide. For example, it can be used as a microreactor to synthesize materials , and can realize the separation of organic solvents under the action of CO 2 . In addition, we are conducting research on a CO 2 stimulation responsive SFME for cleaning oil sands and oil-based drill cuttings.…”

CO₂-Responsive Surfactant-Free Microemulsion

A surfactant-free microemulsion (SFME) with CO stimuli responsive properties was prepared. The oil and the water phases were N, N-dimethylcyclohexylamine (DMCHA) and deionized water, respectively, and N, N-dimethylethanolamine was used as an amphisolvent. The single-phase and multiphase zones were measured by the ternary-phase diagram, and the microstructure of the SFME was determined by measuring the change trend of the electrical conductivity of the system with increasing DMCHA content. While using methyl orange as a probe, the microstructure of the SFME was further confirmed by an UV-visible spectrometer. The microstructures of water-in-oil (SFME-I) and oil-in-water (SFME-II) microemulsions were obtained by changing the DMCHA content in the system. The SFME-I system has a significant phase separation after the action of CO. However, with the continuous introduction of CO, the upper phase of DMCHA is gradually protonated and dissolves in the aqueous phase, resulting in a gradual decrease in the volume of the upper phase, and eventually in an aqueous solution of ammonium bicarbonate. For SFME-II, CO does not directly cause phase separation, but eventually it becomes an aqueous solution of ammonium bicarbonate with the addition of CO. Both the water-in-oil structure SFME-I and the oil-in-water structure SFME-II have excellent CO stimuli responsive performance.

“…Several groups have previously used TEM to identify the crystal structure of SnS nanoparticles (Lu et al, 2015;Tarkas et al, 2017), nanosheets (Hori et al, 2014;Brent et al, 2015;Yang et al, 2015;Chao et al, 2016), nanorods (Suryawanshi et al, 2014;Chauhan et al, 2015) and micron-sized flakes (Xia et al, 2016;Tian et al, 2017) which were synthesised through various techniques. The TEM characterisation of the SnS nanosheets and flakes have been generally limited to plane view analysis and basic d-spacing measurements in cross section in order to confirm the phase of the material.…”

Summary The crystal and defect structure of SnS crystals grown using chemical vapour deposition for application in electronic devices are investigated. The structural analysis shows the presence of two distinct crystal morphologies, that is thin flakes with lateral sizes up to 50 μm and nanometer scale thickness, and much thicker but smaller crystallites. Both show similar Raman response associated with SnS. The structural analysis with transmission electron microscopy shows that the flakes are single crystals of α‐SnS with [010] normal to the substrate. Parallel with the surface of the flakes, lamellae with varying thickness of a new SnS phase are observed. High‐resolution transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), first‐principles simulations (DFT) and nanobeam diffraction (NBD) techniques are employed to characterise this phase in detail. DFT results suggest that the phase is a strain stabilised β’ one grown epitaxially on the α‐SnS crystals. TEM analysis shows that the crystallites are also α‐SnS with generally the [010] direction orthogonal to the substrate. Contrary to the flakes the crystallites consist of two to four grains which are tilted up to 15° relative to the substrate. The various grain boundary structures and twin relations are discussed. Under high‐dose electron irradiation, the SnS structure is reduced and β‐Sn formed. It is shown that this damage only occurs for SnS in direct contact with SiO2.

Ethylene glycol (EG) mediated SnS nanostructures were produced by means of hydrothermal protocol. Preliminary experimental studies confirmed orthorhombic phase SnS nanostructures and its metal oxygen vibrations. Samples interstitial tin (Sn) vacancies on electrochemical activity were discussed. Half cell configuration of electrochemical module was attempted for investigating electrodes electrochemical oxygen evolution reaction (OER) activity. Higheroxygen evolution reaction (OER) activity of SnS@5 ml EG was reported fromlinear sweep voltammetry (LSV) current density as 288 mA/g and also reported lower overpotential of 254 mV. Excellent current density of 81 % retention was achieved for same candidate and is strongly recommended for future energy conversion applications.
