Due to their inexpensive nature and easy handling, they have been widely employed. Their application as an active anode material, which generates a conductive and insoluble layer of NiOOH in alkaline media, gives access to a selective oxidizing system. While using NiOOH anodes as an electrocatalyst has already emerged in the past and was rediscovered lately, the use of nickel foam electrodes as a highly active cathode material for the reduction of organic compounds has strongly evolved only within the last decade. Electroreductions on nickel foam can be carried out in both alkaline and acidic media, as well as under protic and aprotic conditions, enabling a broad range of transformations. The affordability, high electrical conductivity, large electrode surface area, and specific electrocatalytic features are in combination unique and unmatched by any other electrode material. The developments and, in particular, recent breakthroughs for this electrode material in electro-organic synthesis are surveyed.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e70152"},"PeriodicalIF":7.5,"publicationDate":"2026-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147715617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molybdenum disulfide (MoS2), as a highly promising non-precious metal catalyst, has garnered significant attention in this field. This review systematically outlines the latest research advances in MoS2-based materials for the electrocatalytic hydrogen evolution reaction. Focusing on key bottlenecks such as its inherent poor conductivity and basal plane catalytic inertness, it thoroughly explores effective pathways for synergistically regulating electronic structure and surface properties through multidimensional strategies. These include phase engineering (inducing 2H-1T phase transformation), defect engineering (creating sulfur/molybdenum vacancies), elemental doping (introducing nonmetallic/metallic heteroatoms), and composite structure construction (forming heterojunctions with carbon materials, etc.). It systematically analyzes the mechanisms by which these strategies increase active site density, optimize hydrogen adsorption free energy, and enhance charge transport efficiency. Furthermore, it outlines future challenges and development directions for industrial applications, providing important references for designing high-performance MoS2-based electrocatalysts.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e70130"},"PeriodicalIF":7.5,"publicationDate":"2026-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147716346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In view of this, various sets of pyrrolobenzodiazepines were synthesized by modulating the ring position or by adding other pharmacophores to enhance the molecules' efficacy. This review is primarily concerned with retrosynthetic, functionalization, and green synthesis of pyrrolobenzodiazepines (1965-2025), followed by an in-depth discussion of their various biological properties, highlighting structure-activity relationships, molecular docking, and in vitro and in vivo studies on pyrrolobenzodiazepines.

This review surveys and systematically elucidates the physicochemical mechanisms underlying the aerosol-liquid-solid (ALS) transformation during spray deposition, focusing on three core stages: aerosol generation (via pneumatic, electrospray, or ultrasonic methods), droplet deposition and wetting dynamics, and liquid-to-solid crystallization. The interplay among precursor properties, spray parameters, and substrate characteristics dictates film morphology, crystallinity, and defect density. We highlight optimization strategies, including solvent engineering, additive incorporation, and process control, that enable the growth of dense, vertically aligned, and large-grained perovskite films with thicknesses up to hundreds of micrometers. Furthermore, the integration of dimensional engineering and heterojunction design through sequential spray deposition enhances charge transport, suppresses ion migration, and improves detection performance. Applications of these films are demonstrated in direct X-ray detectors and filter-free narrowband photodetectors with high sensitivity, low detection limits, and excellent spatial resolution. Remaining challenges are also discussed in understanding dynamic phase transitions and ensuring large-area uniformity of the spray-deposited films. Advancing in situ characterization and intelligent process control will accelerate the transition of spray coating from a laboratory technique to a scalable precision-manufacturing platform for next-generation perovskite optoelectronics.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e202500358"},"PeriodicalIF":7.5,"publicationDate":"2026-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147715740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
