: The aim of this study was to determine if performing ultrasound-guided, bilateral, two-level cervical sympathetic chain blocks (2LCSBs) (performed on subsequent days) improves symptoms associated with traumatic brain injury (TBI) that do not overlap with posttraumatic stress disorder (PTSD). : A retrospective chart review was conducted between August 2022 and February 2023. We identified twenty patients who received bilateral 2LCSBs for PTSD and anxiety symptoms and who also had a history of TBI.

Cross-Dehydrogenative Coupling of Secondary Amines with Silanes Catalyzed by Agostic Iridium-NSi Species.

Inorg Chem

January 2025

Departamento de Química Inorgánica, Instituto de Síntesis Química y Catálisis Homogénea (ISQCH), Facultad de Ciencias, Universidad de Zaragoza - CSIC, 50009 Zaragoza, Spain.

An active catalytic system for the cross-dehydrogenative coupling (CDC) of a wide range of secondary amines with silanes is reported. The iridium(III) derivatives [Ir(H)(X)(κ-NSi)(L)] (NSi = {4,8-dimethylquinoline-2-yloxy}dimethylsilyl; L = coe, X = Cl, ; L = coe, X = OTf, ; L = PCy, X = Cl, ; L = PCy X = OTf, ), which are stabilized by a weak yet noticeable Ir···H-C agostic interaction between the iridium and one of the C-H bonds of the 8-Me substituent of the NSi ligand, have been prepared and fully characterized. These species have proven to be effective catalysts for the CDC of secondary amines with hydrosilanes.

Multifunctional Optimization of MXene for Enhanced Comprehensive Performance of Crystal Silicon-MXene Back-Heterojunction Solar Cells.

Small

December 2024

LONGi Institute of Future Technology, and School of Materials & Energy, Lanzhou University, 222 South Tianshui Road, Lanzhou, Gansu, 730000, China.

Enhancing the cost-performance ratio is a fundamental objective for the advancement of the photovoltaic sector. In this context, the development of innovative solar cells that offer a straightforward device configuration but high performance is arguably the most crucial element. Herein, an undoped back-heterojunction crystalline silicon (c-Si) solar cell is endeavored to be crafted by simply drop-casting a TiCT MXene ethanol colloidal solution onto the backside of an n-type c-Si (n-Si) wafer.
