As a two-dimensional (2D) material, molybdenum disulfide (MoS2) exhibits unique electronic and optical properties useful for a variety of optoelectronic applications including light harvesting. In this article, we review recent progress in the synthesis, properties and applications of MoS2 and related heterostructures. Heterostructured materials are developed to add more functionality or flexibility compared to single component materials. Our focus is on their novel properties and functionalities as well as emerging applications, especially in the areas of light energy harvesting or conversion. We highlight the correlation between structural properties and other properties including electronic, optical, and dynamic. Whenever appropriate, we also try to provide fundamental insight gained from experimental as well as theoretical studies. Finally, we discuss some current challenges and opportunities in technological applications of MoS2.
Liquid-liquid equilibria (LLE) for the aqueous 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF 4 ) + kosmotropic salt (Na 3 PO 4 , Na 2 CO 3 , Na 2 SO 4 , NaH 2 PO 4 , NaCl) systems have been determined experimentally at T) 298.15 K and in part at T ) (313.15 to 333.15) K. The binodal curves are fitted to an empirical nonlinear expression developed by Merchuk, and the tie lines were described by the Othmer-Tobias and Bancroft equations. Factors affecting the binodal curves such as salts and temperature are also studied. It was found that the salting-out ability of different salts may also be related to the Gibbs energy of hydration of the ions, and the order of salting-out ability of the anions follows the Hofmerister series for the strength of the kosmotropic salts. It was also demonstrated that the two-phase area was expanded with a decrease in temperature.[Bmim]BF 4 could be recovered from aqueous solution using the aqueous two-phase system (ATPS), and the recovery efficiency could reach 98.77 %. The recovery efficiency was influenced by the concentrations of the salts and their Homeister series: Na 3 PO 4 > Na 2 CO 3 > Na 2 SO 4 > NaH 2 PO 4 > NaCl. These data are exposed to be useful for the development and design of the extraction process using ILs based on the ATPS. This proposed method also provided an effective route for the recovery of hydrophilic IL from aqueous solutions.
The Lyz-MMIPs displayed a uniform core–shell structure, favorable magnetic properties, good accessibility, and good stability and had a good affinity and excellent binding selectivity to Lyz.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
