Pretreating bioreactor inocula at elevated temperatures slows methanogenesis in the short term, but over the long term, methanogenic activity often recovers. Here, we examined whether elevated temperatures or “heat shocks” (HSs) applied at the onset of CH4 production can inhibit methanogenesis and increase VFA generation. The effects of multiple 15–30 min intermittent HSs at 50, 65, or 80 °C on mesophilic bioreactors compared to controls at 37 °C were studied. All HS temperatures significantly reduced CH4 production (70–90%) without decreasing VFA production. After 135 days, total VFA concentrations in the HS treatments were around four times larger than the controls. The HSs led to appreciable shifts in the VFA profiles. Longer-chain VFAs, especially caproate, increased more than 6-fold in the 65 °C treated bioreactors. The microbial communities in the HS bioreactors were significantly different than the controls. The relative abundances of putative chain-elongating bacteria increased and those of syntrophic acetate-forming bacteria decreased when the HSs were applied. Our findings show that intermittent HSs may provide a chemical-free methanogen-specific strategy to improve the production of VFAs, especially longer-chain species.","PeriodicalId":7008,"journal":{"name":"ACS ES&T engineering","volume":"4 7","pages":"1725–1737"},"PeriodicalIF":7.4,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141530550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The atmosphere is an alternative freshwater reservoir that has universal availability and could be harvested as drinking water. In order to effectively perform atmospheric water harvesting (AWH), we need to (1) understand how different climate regions (e.g., arid, temperate, and tropical) drive the amount of water that can be harvested and (2) determine the cost to purchase, operate, and power AWH. This research pairs thermodynamics with techno-economic analysis to calculate the water productivity and cost breakdown of a representative condensation-based AWH unit with water treatment. We calculate the monthly and annual levelized cost of water from AWH as a function of climate and power source (grid electricity vs renewable energy from solar photovoltaics (PV)). In our modeled unit, AWH can provide 1744–2710 L/month in a tropical climate, 394–1983 L/month in a temperate climate, and 37–1470 L/month in an arid climate. The levelized cost of water of AWH powered by the electrical grid is $0.06/L in a tropical climate, $0.09/L in a temperate climate, and $0.17/L in an arid climate. If off-grid solar PV was purchased at the time of purchasing the AWH unit to power the AWH, the costs increase to $0.40/L in an arid climate, $0.17/L in a temperate climate, and $0.10/L in a tropical climate. However, if using existing solar PV there are potential cost reductions of 4.25–5-fold between purchasing and using existing solar PV, and 2–3-fold between using the electrical grid and existing solar PV, with the highest cost reductions occurring in the tropical climate. Using existing solar PV, the levelized cost of AWH is $0.09/L in an arid climate, $0.04/L in a temperate climate, and $0.02/L in a tropical climate.","PeriodicalId":7008,"journal":{"name":"ACS ES&T engineering","volume":"4 7","pages":"1769–1780"},"PeriodicalIF":7.4,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsestengg.4c00098","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141507802","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, previous studies have primarily focused on specific pollutants due to the limited electrical band structure of fluorescence nanosensors. Therefore, to broaden the applicability of fluorescence detection techniques, it is critical to develop a new fluorescence nanosensor with a diversified spectrum (macroscopically represented by multiple colors). In this work, four different colored carbon quantum dots (CDs) were prepared without the need for additional separation or purification steps. Through comprehensive characterization and theoretical modeling, the fluorescence colors were attributed to size effects, configuration, and the spatial location of nitrogen. The mechanism of fluorescence excitation and emission in the as-prepared nanosensor was clearly illustrated using hole–electron analysis. Furthermore, a test set comprising universal heavy metals and antibiotics was employed to investigate the feasibility of the rapid fluorescence detection of multicolor CDs. Additionally, a smartphone-app-based fluorescence color detection device was developed to complete the high-throughput in situ examination of real water samples. This work offers a new perspective on broadening the application of fluorescence detection technology and serves as a resource for rapid, high-volume, and in situ fluorescence detection of water pollutants.","PeriodicalId":7008,"journal":{"name":"ACS ES&T engineering","volume":"28 1","pages":""},"PeriodicalIF":7.1,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141507801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
