This study investigates the solubility of these acids in renewable glycerol-derived ethers, which exhibit good ecotoxicological profiles and tunable physicochemical properties. Experimental solubility data revealed that monoethers and diethers with shorter alkyl chains significantly enhance the solubility of the studied hydroxycinnamic acids. The findings were further corroborated by COSMO-RS modeling, highlighting the importance of both hydrogen-bond donor capacity and polarity-polarizability in solubility enhancement. Hydrotropic effects of glycerol ethers in water were also experimentally demonstrated, indicating their potential in pharmaceutical and industrial formulations. These results underscore the efficacy of glycerol-derived solvents as sustainable alternatives for solubilizing hydroxycinnamic acids, paving the way for greener and more efficient applications.</p><p >Glycerol ether solvents exhibit outstanding properties and hydrotropic ability for the solubilization of hydroxycinnamic acids: ferulic, coumaric, and caffeic acids.</p>","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"13 23","pages":"8556–8566 8556–8566"},"PeriodicalIF":7.1,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acssuschemeng.5c00269","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144290363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Betaine served as the hydrogen bond acceptor (HBA), paired with seven organic acids as hydrogen bond donors (HBDs), to examine the impact of the HBD structure (specifically carbon chain length and functional groups) on the pretreatment process. Results showed that increasing carbon chain length enhanced protein solubilization but could limit biomass depolymerization, whereas unsaturated bonds facilitated both depolymerization and solubilization, improving the lipid yield. Characterization of hydrochar by TGA and FTIR elucidated structural changes in pretreated microalgae, revealing that the HBD structure, through its influence on NADES acidity and molecular polarity index determined by quantum chemical calculations, affected both depolymerization and solubilization of microalgae. Life cycle assessment indicated that while not all NADES surpassed Syn-DES in performance, the betaine-malic acid NADES demonstrated a superior net energy ratio (NER) of 0.21 (compared to 0.24 for Syn-DES) and reduced CO₂ emissions by 15.36%. Additionally, USEtox modeling showed a 2-order-of-magnitude reduction in ecotoxicity with this NADES. These findings underscore the potential of tailored NADESs to enhance the sustainability and efficiency of biodiesel production from microalgae.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"52 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study provides the first comprehensive evaluation of the chronic effects of hydrogen NB water on the growth and reproduction of <i>Daphnia magna</i> (<i>D. magna</i>) under copper stress, uncovering key molecular pathways and pivotal genes. Over prolonged exposure, hydrogen NB water promoted the growth and reproduction in <i>D. magna</i>. Mechanistically, transcriptomic analysis revealed that hydrogen NB water promotes protein hydrolysis by upregulating <i>carboxypeptidase A</i>, boosting energy metabolism, and facilitating molting through the upregulation of <i>Chitinase</i>. In addition, hydrogen NB water attenuated retinol metabolism by upregulating <i>retinol dehydrogenase</i>, thereby influencing signal transduction pathways. In reproduction, hydrogen NB water significantly enhances prostaglandin synthesis by upregulating <i>prostaglandin synthase</i> and <i>carbonyl reductase</i>, improving energy homeostasis and reproductive capacity.

Here, a green proton-exchanged solid acid catalyst was developed to efficiently convert high-concentration fructose (15.6 wt %) into 5-hydroxymethylfurfural (HMF). The catalyst was synthesized by carbonizing a precursor formed from ammonium sulfate and sodium lignosulfonate (LS), followed by proton exchange. Carbonization at 350 °C preserved the −SO₃Na functional group in the LS precursor, while ammonium sulfate promoted pore formation. The retained −SO₃Na groups were subsequently converted to the −SO₃H active sites of the catalyst by a proton-exchange reaction. The total acid density of the proton-exchanged solid acid catalyst reached 5.26 mmol/g. In the DMSO system, the proton-exchanged catalyst achieved 99% fructose conversion and 82% HMF yield under high fructose concentration. In addition, it maintained stable activity over 6 cycles. The strategy of incomplete carbonization and proton exchange of LS not only maintains the catalytic performance but is also a green and sustainable alternative to the sulfonation method.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"17 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
