In recent years, formic acid (FA) has garnered attention as a compelling molecule for various chemical and everyday applications Additionally, with recent studies demonstrating direct FA generation through CO2 electrolysis, it can serve as a stable liquid hydrogen carrier. Nevertheless, FA-permeability via semi-permeable ion‑exchange membranes (FA-crossover) still constitutes a major issue in scalable polymer-electrolyte separated zero-gap electrolyzers, limiting the breakthrough of the technology to the larger-scale. Herein we present a holistic route towards understanding the mechanism of FA-crossover in zero-gap cells.

Strategies for combining ionic and non-ionic functional groups are important for altering detergent properties and exploring new chemical spaces within the detergentome. Previous synthesis protocols for ionic/non-ionic hybrid detergents require asymmetric detergent precursors with independently addressable hydroxyl groups that can be decorated with charged groups. However, preparation of ionic/non-ionic headgroups can be tedious in terms of required synthesis steps and resource consumption.

Lumbar disc herniation (LDH) affects millions globally, with annual healthcare costs exceeding $100 billion in the United States alone, driving increasing interest in minimally invasive radiological interventions as treatment alternatives. This narrative review examines developments in collagenase chemonucleolysis for LDH, integrating a literature analysis with clinical experience. Key advancements include the transition from single-agent to combination therapies, exploration of diverse injection routes, and the progression from C-arm fluoroscopy to multi-slice CT guidance.

In recent years, bone marrow derived mesenchymal stem cells (BM-derived MSCs) have emerged as a powerful cell-based therapy for various diseases, including male infertility. Demonstrating the efficiency of BM-derived MSCs transplantation by different routes of injection to home and repair testis of busulfan-induced azoospermic rats. In the present study, rat BM-derived MSC was isolated and characterized for mesenchymal &hematopoietic markers using flow-cytometry.
