Zeitschrift für anorganische und allgemeine Chemie, Volume 650, Issue 13-14, July 2, 2024.Abstract Methanesulfonic acid, CH3SO3H, has been crystallized using an in situ technique on a single crystal diffractometer. The crystal structure is monoclinic (P21/c, Z=4, a=842.07(4) pm, b=582.20(3) pm, c=820.38(4) pm, β=106.459(2)°) and stamped by the presence of strong hydrogen bonds.

A two‐stage solution method for the design problem of medium‐thick plates in steel plants
IET Collaborative Intelligent Manufacturing, Volume 6, Issue 1, March 2024.The design of the mother plate is an important part in the production process of a medium‐thick plate, which includes the combination of sub‐plates and the size design of plate. In this study, a multi‐objective model for medium‐thick plate design is proposed based on the 2D bin packing model.

Triflate's bigger brother: The unprecedented tribrate anion, [Br3CSO3]−
Chemistry – A European Journal, Volume 30, Issue 11, February 21, 2024.The tribromomethansulfonate anion (“tribrate”), [Br3CSO3]−, has been prepared for the first time. The anion is, up to now, the biggest brother of the well‐known triflate anion. Key step of the synthesis is the bromination of phenyl‐methanesulfonate by KOBr.
