(RPhP)[Mn(dca)]: A Family of Glass-Forming Hybrid Organic-Inorganic Materials.

ABX-type hybrid organic-inorganic structures have recently emerged as a new class of meltable materials. Here, by the use of phenylphosphonium derivatives as A cation, we study liquid- and glass-forming behavior of a new family of hybrid structures, (RPhP)[Mn(dca)] (R = Me, Et, Ph; dca = dicyanamide). These new compounds melt at 196-237 °C () and then vitrify upon cooling to room temperature, forming glasses.

Medium-term results of arthroscopic hip surgery compared with physiotherapy and activity modification for the treatment of femoroacetabular impingement syndrome: a multi-centre randomised controlled trial.

Objective: To report a 3-year follow-up from the FemoroAcetabular Impingement Trial, comparing arthroscopic surgery with physiotherapy in the management of femoroacetabular impingement (FAI) syndrome for the dual primary outcomes of radiographic hip osteoarthritis (OA) and patient-reported outcome measures of activities of daily living.

Methods: Two-group parallel, assessor-blinded, pragmatic randomised controlled trial across seven sites. 222 participants aged 18-60 years with FAI syndrome confirmed clinically and radiologically were randomised (1:1) to receive arthroscopic hip surgery (n=112) or physiotherapy (n=110).

Melt Alloying of Two-Dimensional Hybrid Perovskites: Composition-Dependence of Thermal and Optical Properties.

Melt alloying, the process of melting a physical powder blend to create a homogeneous alloy, is widely used in materials processing. By carefully selecting the materials and their proportions, the physical properties of the resulting alloy can be precisely controlled. In this study, we investigate the possibility of utilizing melt alloying principles for meltable two-dimensional hybrid organic-inorganic perovskites (2D-HOIPs).

Threshold photoelectron spectroscopy of organosulfur radicals.

We report vibrationally resolved threshold photoelectron spectra of several sulfur-containing reactive intermediates. This includes the organosulfur radicals CHS, CHS, CHSH, CHS, and SH, which are relevant in atmospheric chemistry and in astrochemical settings. Due to the high reactivity, the radicals were prepared pyrolysis of (CH)S.
