Nuclear magnetic resonance (NMR) and total neutron scattering techniques are established methods for the characterisation of liquid phases in confined pore spaces during chemical reactions. Herein, we describe the first combined total neutron scattering - NMR setup as a probe for the catalytic heterogeneous reduction of benzene-d6 with D2 in 3 wt% Pt/MCM-41.

Aim Of The Study: The aim of the study is to describe clinical features, treatment approach and outcomes of recurrent/metastatic (R/M) NPC in non-endemic areas MATERIALS AND METHODS: This observational, retrospective and multicenter study was conducted within 36 referral hospital in non-endemic areas including Europe, Jordan, Kuwait, Turkey and United States of America. All NPC patients diagnosed between 2004 and 2016 and with a minimum 12 months of follow-up were included. Data entry started in January 2018 and closed in December 2023.

This work reports the nanoscale micellar formation in single and mixed surfactant systems by combining an amphiphilic graft copolymer, Soluplus® (primary surfactant), blended with other polyoxyethylene (POE)-based nonionic surfactants such as Kolliphor® HS15, Kolliphor® EL, Tween-80, TPGS®, and Pluronics® P123 in an aqueous solution environment. The solution behaviour of these surfactants as a single system were analyzed in a wide range of surfactant concentrations and temperatures. Rheological measurements revealed distinct solution behaviour in the case of Soluplus®, ranging from low-viscosity () and fluid-like behavior at ≤20% w/v to a highly viscous state at ≥90% w/v, where the loss modulus ('') exceeded the storage modulus (').

Water-in-Salt (WiS) electrolytes are an emerging class of high concentration aqueous electrolytes with large electrochemical stability windows, making them attractive as green alternatives in next-generation electrochemical energy storage devices. Recent work has highlighted the existence of water-rich and anion-rich domains in WiS electrolytes, but the extent, morphology and importance of these domains are still disputed. Here, we present neutron total scattering measurements of the archetypal WiS, lithium bis(trifluoromethanesulfonyl)imide, and use empirical potential structure refinement to match the structure of a simulated system to the experimental data for two technologically relevant concentrations, revealing ion solvation, geometric isomerism and long-range structures in unprecedented detail.

Heteroanionic materials can provide a powerful platform for tuning the local structure and electronic properties through targeted chemical substitution. Among them, heteroanionic pyrochlores offer exceptional flexibility due to their robust framework and capacity to host both cation and anion disorders. In this study, we investigate the structure-property relationship in sulfur-doped tin niobate SnNbOS, a lone pair-active pyrochlore where substitution of sulfur into the O' site systematically modulates both the electronic structure and local coordination environments.

BNCT is a radiotherapeutic modality of high LET energy for different solid tumors as colorectal carcinoma (CRC). Although clinical outcomes show advantages of BNCT, tumor recurrence remains a common challenge. Previously we have described the double strand DNA damage response (DDR) produced by BNCT.
