With an ever-increasing prevalence, the need for precise detection of these chemicals at low levels in drinking water is clear. However, ground and surface water as well as soil and other biosolids have become reservoirs for PFAS at extremely high levels. In fact, PFAS concentrations at part per billion and part per million levels are found in environmental samples taken near high contamination sites including industrial facilities and military bases. In this work, we demonstrate the application of a biosensor based on human liver fatty acid binding protein to detect perfluorooctanoic acid (PFOA) in surface water samples taken near Loring Airforce Base. We show this sensor can detect the high levels of PFOA found in the samples quickly and easily without the use of extensive sample pre-treatment or analytical methods. Therefore, we hope the future of this technology will better assess PFAS detection needs for a multitude of end point users.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11525949/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142570577","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}

Specifically, we review the optimization of hydrogel materials for diverse microbial applications related to green microbiology, the use of microbes to promote sustainability. Hydrogels, three-dimensional polymers networks with high water retention capabilities, are pivotal in the immobilization of microorganisms and provide a customizable environment essential for directing microbial fate. We focus on the application of DOE to precisely tailor hydrogel compositions for a range of fungi and bacteria either used for the sustainable production of chemical compounds, or the elimination of hazardous substances. We examine a variety of DOE design strategies such as central composite designs, Box-Behnken designs, and optimal designs, and discuss their strategic implementation across diverse hydrogel formulations. Our analysis explores the integral role of DOE in refining hydrogels derived from a spectrum of polymers, including natural and synthetic polymers. We illustrate how DOE facilitates nuanced control over hydrogel properties that cannot be achieved using a standard one factor at a time approach. Furthermore, this review reveals a conserved finding across different materials and applications: there are significant interactions between hydrogel parameters and cell behavior. This highlights the intricacies of cell-hydrogel interactions and the impact on hydrogel material properties and cellular functions. Lastly, this review not only highlights DOE's efficacy in streamlining the optimization of cell-hydrogel processes but also positions it as a critical tool in advancing our understanding of cell-hydrogel dynamics, potentially leading to innovative advancements in biotechnological applications and bioengineering solutions.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11499971/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142516808","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}

Unlike most CO2-philic POPs, which often require organic solvents, high temperatures, catalysts, additives, or hydrothermal equipment, these new polymers are synthesized in pure water at a relatively low temperature (70 °C) without any catalysts or additives and using common glassware. The N-rich composition of these porous organic polymers also contributes to their high adsorption selectivity for CO2 over N2, as calculated with the IAST method at 298 K.

For this reason, the development of alternative catalysts such as ZnZrO x has attracted considerable interest, given its superior stability and versatility in comparison to the conventional Cu-based materials. In this work, ZnZrO x has been produced by a hydrothermal synthesis method at varied synthesis pH between 7 and 10 and a positive association between pH and catalytic CO2 conversion is observed. At 2.0 MPa and 250 °C, ZnZrO x produced at pH 10 shows a methanol selectivity of 95% at a CO2 conversion of 3.4%. According to characterization, basic pH conditions enable the formation of abundant t-ZrO2 and the subsequent incorporation of Zn2+ into this phase, although the content of surface Zn does not increase between pH 8 and 10. Nevertheless, synthesis pH values can be correlated with surface oxygen content and CO2 adsorption capacity, which could be important contributors to the higher catalytic activity observed as a result of higher synthesis pH values. However, upon synthesis at pH 10, an inferior selectivity to methanol is observed above 250 °C, as a possible result of the excessive formation of ZnO. Interestingly, this secondary phase can be prevented and the selectivity can be slightly improved by utilizing NH4OH instead of NaOH in the hydrothermal method.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11484158/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142482701","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}

This study reports the successful deposition of uniform ∼1.0 nm metallic ruthenium (Ru) nanoclusters onto Ba–LaCeOx particles via atomic layer deposition (ALD). The catalytic performance of the ALD-prepared Ru nanoclusters was assessed for ammonia synthesis and compared with two catalysts produced by conventional incipient wetness impregnation. For the ALD-prepared Ru nanoclusters, a pre-reaction H2-reduction step induced partial encapsulation of suboxide species on Ru sites due to strong metal–support interactions, limiting Ru nanocluster sintering and maintaining a reduced Ru size of 1.7 nm. The electron donation from the reduced support to Ru sites imparted an electron-rich character, which facilitated the weakening of the N<img>N bond and promoted the rate-determining step of ammonia synthesis. The ALD-Ru catalysts exhibited competitive ammonia synthesis activity under milder conditions, compared to the impregnated catalysts, with a lower requirement for initial reaction temperature. These results highlight the potential of ALD-synthesized Ru nanoclusters as highly efficient catalysts for low-temperature ammonia production, offering a promising avenue for advancing ammonia synthesis technologies.","PeriodicalId":74745,"journal":{"name":"RSC sustainability","volume":" 11","pages":" 3507-3519"},"PeriodicalIF":0.0,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/su/d4su00350k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142565744","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}
