In this line, synthesis methods and properties for biomedical applications are rarely reviewed in the current literature. More importantly, challenges and opportunities for possible real-world biomedical applications need to be addressed to attract researchers in this emerging field. Here, we review the various synthesis methods/schemes for vitrimer preparation to achieve desired properties for specific applications. We have classified these different synthesis methods/schemes into monomers during transesterification, disulfide and imine exchanges, and discuss this focusing on recent examples. Then we discuss exchange-based properties, i.e., recyclability, healing ability, shape memory, and adhesive nature for biomedical prospects, including self-healing coatings, recyclable polymers, 3D printing, and biodegradable medical equipment.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 846-867"},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/lf/d4lf00101j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142165120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the current literature lacks a clear path for leveraging silver functionalization in designing biofouling-resistant PA membranes mainly due to huge variations in the resulting silver loading on the membrane. To help develop a robust procedure for fabricating AgNP-loaded PA membranes, here we investigate the relationship between loading yield and membrane (surface) properties. We selected four commercially available PA TFC membranes (BW 30, SW 30 XLE, AMI H, NF 270) and decorated those with AgNPs using the same functionalization chemistry. As expected, we observed a clear variation in silver loading (in the order of BW 30 > AMI H > SW 30 > NF 270). To elucidate the role of membrane surface properties in determining the silver loading efficacy, we conducted a detailed surface characterization of PA TFC membranes using atomic force microscopy, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, streaming potential analysis, and contact angle measurements. Subsequently, we employed multiple linear regression analysis to correlate surface properties with silver loading. Our investigation revealed that oxygen content significantly influences AgNP loading (p < 0.05), more than any other surface characteristics. These results will guide future material selection for reverse osmosis or nanofiltration applications critical in the water sector in short term. Moreover, the insights gained from this work are expected to be pivotal in developing membranes more suitable for fabricating AgNP-loaded antimicrobial membranes.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 6","pages":" 1186-1197"},"PeriodicalIF":0.0,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/lf/d4lf00088a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The new solid-phase electrodeposition system includes a thin layer of electrolyte solution between the anode and the membrane that comes into contact with the cathode. This layer was introduced to enable the electrolyte solution to be circulated to maintain the concentration of copper ions in the solution phase during electrodeposition. This membrane–solution layered system has a greater steady-state current density under constant-voltage electrodeposition compared with the previous system in which the membrane was sandwiched between the electrodes. The higher current density was attributed to the higher ion penetration rate at the interface between the electrolyte solution and the membrane, as verified by the results of the numerical analysis of the ion transport kinetics in the new system. By positioning the anode such that it is set slightly apart from the polyelectrolyte membrane to allow the electrolyte phase to be introduced, but as close as possible to it, a current density that was at maximum 50% greater than that of the sandwiched system was realized at steady state. This increase, which is attributed to the maximum ion penetration rate and minimum resistivity of the electrolyte layer, ensures a more efficient deposition setup for high-performance electrodeposition.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 1069-1076"},"PeriodicalIF":0.0,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/lf/d4lf00112e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142165115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An effective hydrogen evolution reaction (HER) catalyst with decreased overpotentials and long-term stability is a necessity for electrochemical water splitting to fulfil the needs of the hydrogen economy. Slack anchoring of an active electrocatalyst on the substrate can significantly lead to a decline in its performance in any system. This study focuses on the synthesis of molybdenum sulphide (MoS2) quantum dot-modified MXene nanoflowers (MQD@NFs) by hydrothermal treatment. Further analysis shows that MQDs have been successfully embedded inside the nanoflowers, which facilitate electron transfer and provide a stable structure. MQD@NFs exhibited excellent catalytic activity towards HER in an acidic environment and achieved HER performance at a current density of 10 mA cm−2, with an overpotential of 307 mV and a Tafel slope of 68.5 mV dec−1 in 0.5 M H2SO4. Additional catalytic sites on synthesized MQD@NFs enhance ceaseless efforts toward the facile synthesis of economically viable electrocatalysts for hydrogen generation. A graphite rod of 3 mm diameter was employed as the counter electrode with the synthesized working electrode and reference electrode to evaluate the HER performance.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 5","pages":" 1057-1068"},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/lf/d4lf00106k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142165114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The phenomenon is known as “fomite transmission”, where pathogens can survive on surfaces for varying periods, depending on the material and environmental conditions. Fomite transmission plays a significant role in spreading infectious diseases. This transmission route is particularly relevant in high-traffic environments like healthcare facilities, public transportation, schools, etc. Developing surfaces with bactericidal or antiviral properties and designing spaces to minimize surface contact are strategies to reduce the risk of fomite transmission. This is where the concept of nature-inspired bactericidal surfaces becomes valuable. Nature offers sustainable surface design for preventing bacterial colonization and growth. Crafting nature-inspired bactericidal surfaces can lead to the development of materials that can help prevent the spread of infections, reduce the need for frequent cleaning, and potentially contribute to healthcare and hygiene applications. To minimize human health and environmental issues, instead of using harmful disinfectants regularly in public places, nanoengineered surfaces with antipathogen features could alternatively halt microbial growth to prevent the risk of establishing a surface-contamination network. In infectious disease control, this work aims to provide a detailed overview and perspective on the importance of developing nature-inspired bactericidal surfaces to combat surface contamination issues. This approach holds the potential to offer more sustainable and practical solutions compared to traditional methods of using disinfectants and harsh chemicals.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 4","pages":" 648-666"},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/lf/d3lf00267e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141561096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When cycled in commercially relevant graphite/LiNi0.8Mn0.1Co0.1O2 (NMC811) pouch cells, these electrolytes demonstrate improved capacity retention compared to carbonate-based electrolytes under multiple usage conditions including high voltage (4.5 V), fast charge (4C, 15 minutes), and low temperature (−20 °C) without sacrificing capacity retention at elevated temperature (40 °C). Low carbon, high fluoride cathode electrolyte interphases formed by the LHCE system yield a significant reduction in charge transfer impedance during cycling and contribute to capacity retention.

Nanomaterials are widely used in cutting-edge assays for the selective and sensitive detection of a wide range of analytes. Nanoclusters (NCs) are a novel emerging type of nanomaterials in terms of their outstanding stability and ease of fabrication. Herein, two different types of green emissive copper nanoclusters (CuNCs) were synthesized using sodium cholate (NaC) and sodium taurocholate (NaTC) as bile salts, which act as templating agents and hydrazine hydrate as a reducing agent in ambient conditions. The as-prepared CuNCs exhibited highly fluorescent, outstanding solubility in an aqueous medium and significant Stokes shift. The particle size of both CuNCs (NaC@CuNCs and NaTC@CuNCs) was examined using high-resolution transmission electron microscopy (HRTEM) analysis, which confirms their size within the 2.2–2.7 nm range. The surface functionality and chemical compositions of both CuNCs were determined using X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectroscopy. The prepared CuNCs showed good pH stability and ionic stability. Both nanoprobes have high sensitivity and selectivity for the determination of 4-NP. The values of quantum yield and average lifetime have been evaluated to confirm the inner filter effect (IFE) quenching mechanism. Based on this, simple and accurate turn-off fluorescent nanoprobes, NaC@CuNCs and NaTC@CuNCs were created to detect 4-NP with a detection limit of 47.1 nM and 58.4 nM, respectively. Real sample analyses were performed to assess the viability of the detection technique, revealing good recovery rates and relative standard deviations towards the proposed probes. Therefore, the developed nanoprobe may be applied for on-site and fast detection of 4-NP.","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 6","pages":" 1174-1185"},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/lf/d4lf00143e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
