Particularly, three aluminosilicate mesostructured acid catalysts with catalytic activity towards methanol dehydration and featuring different porous structures (Al-MCM-41, Al-SBA-15, Al-SBA-16) were synthesized and used as supports to host a CuO/ZnO/ZrO2 (CZZ) CO2 hydrogenation catalyst for methanol synthesis. The use of a mesostructured support allows to maximize the exposed surface of the CO2 reduction function by nanostructuring it through its confinement within the mesochannels, thus obtaining nanocomposite bifunctional catalysts with an ultra-small hydrogenation nanophase. The nanocomposites were obtained using an impregnation strategy combined with a self-combustion reaction, allowing to incorporate the CO2 reduction phase inside the mesopores. In all cases, the characterization shows that the hydrogenation phase species are highly and homogeneously dispersed into the supports as either small nanoparticles or as a nanolayer. The as-obtained nanocomposites were tested for their catalytic activity and the results discussed taking into account the structural, textural, and acidic properties of the supports and nanocomposites.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202400760"},"PeriodicalIF":3.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. To address this challenge, here we explore if we can fuse ionic and non-ionic groups directly with methallyl dichloride in the first step of detergent synthesis. While this delivers a simplified synthesis strategy for ionic/non-ionic headgroups, we find functional groups for which the modification of asymmetric detergent precursors is still the only viable option to obtain related ionic/non-ionic hybrid detergents. Because previously established debenzylation conditions limit overall yields for asymmetric detergent precursors, here we explore optimization strategies, including silyl protecting groups, ozonolysis-hydrolysis, and hydrogenolysis. In summary, we establish a new synthesis route to ionic/non-ionic hybrid detergents, deliver an optimized debenzylation protocol and obtain building blocks for bridged detergent architectures. Our findings facilitate the modular synthesis of hybrid detergents and expand the chemical space of detergents.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202400753"},"PeriodicalIF":3.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143021333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Irrigation and the provision of appropriate nutrient levels in soil are essential for optimizing plant growth and enhancing crop productivity. To support the increasing need for food due to the growing population worldwide, synthetic fertilizers have been widely used in the agricultural sector. These fertilizers could readily dissolve in the irrigation water or soil moisture, causing excessive release of the nutrients that plants cannot uptake from the root zone. The excess nutrients in the soil further harm the environment via surface run-off, leaching, and volatilization. Thus, materials with high water absorption and retention capacity, and precise control over the prolonged fertilizer release offer a potential solution to address these issues. To meet these requirements, the development of slow-release fertilizer hydrogels (SRFHs) represents a promising approach. SRFHs serve as natural agrochemicals to enhance crop growth and yield through controlled and self-sustained delivery of water and nutrients. This review provides a comprehensive study on the recent advancements in SRFHs, including their preparation methods, properties, slow-release behavior, and applications in smart agriculture. The response of soil microbial diversity to slow-release fertilizers is briefly discussed, and the future potential of SRFHs is highlighted herein.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":"90 3","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142996931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the detergent with the longest fluorinated chain exhibited poor water solubility, the other three derivatives were freely soluble. Dynamic light scattering (DLS) measurements indicated an increase in hydrodynamic diameter with chain length, from 5 nm to 17 nm for the soluble derivatives. We evaluated these detergents for extraction and stabilization of two model membrane proteins, the human adenosine A2A receptor (A2AR) and the Bacillus subtilis multidrug resistance ABC transporter BmrA. The perfluorohexyl derivative demonstrated strong solubilization capacity, while the perfluoro-pentyl derivative was more effective for stabilization.

Their distinct advantages, including a metal-free composition, low toxicity, and facile synthesis under ambient conditions, make them highly desirable. This study examines the delayed fluorescence (DF) and RTP of metal-free, amorphous indenophenanthridine (IND)-based derivatives (1-10) and provides insights into molecular functionalisation and host matrix effects on delayed emission (RTP and DF). IND derivatives have been used in bioimaging and organic analyte detections; however, their delayed emission mechanism photophysical processes are poorly understood. This work examines the derivatives' physicochemical properties and time-resolved photophysics to determine how molecular structure, host interaction, and delayed emission properties relate. The described IND compounds show RTP and/or TTA (triplet-triplet annihilation) delayed fluorescence depending on the host environment. This research lays the groundwork for designing and developing new materials with increased RTP efficiency for future applications by detailing the detailed RTP processes and the crucial function of the host matrix.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202400571"},"PeriodicalIF":3.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142982187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, the treatment methods of industrial solid waste mainly include direct landfill, recovery of high-value components, production of construction materials, etc. These methods not only waste land resources, but also have a limited scope of application. Mining and metallurgical industrial solid wastes are generally characterized by high porosity, certain mechanical strength, and high yield, which can be used as a porous matrix to support phase change materials (PCMs) after modification treatment, thus solving the problem of easy leakage of PCMs. At present, there is no overview of mining industry solid waste in PCM applications.
