Nevertheless, their high viscosity might limit their applications in the transportation field. Developing HIPPEs with adjustable stability, controllable viscosity, and easy preparation remains a challenge. Here, we reported an O/W HIPPEs costabilized by a novel CO₂-switchable nonionic surfactant (NCOEO₃) and hydrophilic silica nanoparticles with low concentrations, facilitated by the adsorption of NCOEO₃ onto the nanoparticles through hydrogen bonding. Upon increasing the NCOEO₃ concentration to 1 mM, the oil volume fraction of the emulsions can be adjusted to 92%. The HIPPEs demonstrate remarkable CO₂ responsiveness due to the reversible transformation of the surfactant structure between nonionic (NCOEO₃) and cationic-nonionic (N⁺COEO₃) forms triggered by CO₂. This responsiveness enables efficient demulsification at room temperature as well as the recycling and recovery of the surfactant within the aqueous phase. More importantly, the inverted highly viscous HIPPEs could be reversibly converted into flowable low viscous HIPPEs through the CO₂ trigger. This research offers an effective method for preparing intelligent HIPPEs with adjustable properties, such as stability, viscosity, and an aqueous recyclable emulsifier, which can meet various practical application needs.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"31 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873953","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}

As the supply of CS heavily relies on chemical conversion of cholesterol extracted from wool grease, there is growing interest in engineering microbial cell factories for large-scale production of CS. This study reports microbial production of CS in the yeast, <i>Komagataella phaffii</i> (also known as <i>Pichia pastoris</i>), for the first time. Through combinatorial metabolic engineering strategies, including blocking the competing branches, overexpressing the rate-limiting mevalonate pathway genes, manipulating lipid metabolism, and enhancing the supply of key cofactor 3′-phosphoadenosine-5′-phosphosulfate (PAPS), CS production was increased more than 6.8-fold when compared with the parent strain. The optimal strain (CHS0505) produced CS with titers reaching 249 mg/L in a shake flask and 545 mg/L in a fed-batch fermenter, highlighting the potential of <i>K. phaffii</i> as a cell factory for steroid production. More importantly, the development of a CS-producing cell factory will advance microbial production of glycosaminoglycans and other sulfated natural products via synthetic biology.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"24 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873954","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}

In this study, a biobased hyperbranched polymer flame retardant named QB was synthesized using quercetin and phenylphosphoryl dichloride by a one-step method. The QB copolymer was characterized via Fourier transform infrared spectroscopy, thermogravimetric analysis, and gel permeation chromatography, revealing its high thermal stability and polymeric nature, with a weight-average molecular weight of 78 299 g/mol. QB was subsequently incorporated into bisphenol A-type epoxy resins using 4–4 diamino diphenylmethane as a curing agent to prepare the flame-retardant epoxy composite. With additions of only 1 wt % QB, EQB-1 achieved a UL 94 V-0 rating in the vertical burning test and an impressive limiting oxygen index (LOI) value of 28.2%. Moreover, the addition of the 3 wt % QB in EP resulted in a maximum reduction of 32.9% in the peak of heat release rate and a 37.4% reduction in the smoke produce rate, indicating its outstanding flame-retardant and smoke suppression properties, which are attributed to a mainly condensed-phase flame-retardant mechanism. Furthermore, the impact and flexural strength of the composite were maintained and a slight improvement was observed. The findings of this research are expected to contribute to the development of environmentally friendly flame-retardant epoxy systems that meet industry standards while promoting the use of renewable materials. This work supports sustainability by replacing petrochemical flame retardants with renewable quercetin-based materials, reducing toxicity and environmental impact.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"287 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873955","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}

The activation energies for the formation of the dimeric and trimeric aldol adducts were similar at 74 and 76 kJ/mol, respectively. Biphasic conditions were employed to prevent product precipitation, leading to reactor and equipment fouling. For biphasic conditions, the extraction of the reactants and dimeric intermediates to the organic phase affected rate and selectivity, resulting in the dilemma. Good product extraction leads to inevitable reactant extraction.

Although PLA is degradable in natural environments, its decomposition postdisposal leads to resource wastage. Herein, we first employ enzymatic hydrolysis to degrade PLA. Subsequently, PtPb alloy nanoparticles are synthesized in a single step via a wet chemical method, catalyzing the reformation of the PLA enzymatic hydrolysis products into higher-value chemicals (pyruvic acid). Under conditions of an oxygen flow rate of 60 mL/min, a reaction temperature of 90 °C, and a reaction duration of 60 min, the conversion rate of lactic acid catalytic oxidative dehydrogenation to pyruvic acid reaches an impressive 96.86%, with a selectivity of 95.69%. Moreover, this catalyst exhibits satisfactory stability. Experimental and density functional theory (DFT) calculations are combined to ascertain the active state changes of PtPb and the reaction pathways for the catalytic oxidative dehydrogenation of lactic acid to pyruvic acid, as well as the free energy changes of different catalysts in this transformation. In this work, we employ a simple synthetic strategy to specifically investigate the impact of PtPb alloy nanoparticles under various conditions on the catalytic oxidative dehydrogenation of lactic acid to pyruvic acid, offering a new research avenue for the waste treatment and resource utilization of biodegradable plastics in the future.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"26 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867442","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}

Notably, most microbial lipoxygenases including the lipoxygenase from <i>Pseudomonas aeruginosa</i> (<i>Pa</i>-LOX) catalyze oxygenation of linoleic acid and arachidonic acid into 13<i>S</i>-hydroperoxyoctadecenoic acid (13<i>S</i>-HPODE) and 15<i>S</i>-hydroperoxyeicosatetraenoic acid (15<i>S</i>-HPETE), respectively. Therefore, this study has focused on modification of positional specificity or regioselectivity of <i>Pa</i>-LOX. The linoleic acid oxygenations and substrate-docking simulations suggested that the regioselectivity of <i>Pa</i>-LOX might depend on the geometry of the hydrocarbon tail-binding cavity. Therefore, the interior end of the substrate-binding cavity was enlarged to make C10 instead of C13 face the iron active site. Remarkably, the M434G mutation led to alteration of the oxygenation products from 15<i>S</i>-hydroxyeicosatetraenoic acid (15<i>S</i>-HPETE) to 11<i>S</i>-HPETE as the major product from arachidonic acid.

In this work, the synthetic methodologies for yielding a transparent, conducting cellulose nanocrystal (CNC) film from a highly abundant crop residue, rice straw (<i>Oryza sp</i>. Stems), have been presented. The self-assembly of CNC generates a predominant structural green color. Even the encapsulation of organic fluorophores in CNC films retains a chiral nematic order and a photonic band gap. The highly crystalline nature of the hydroxyl groups present in CNC regulates the excited-state dynamics of Rhodamine B encapsulated in the film. Nevertheless, the transreflective property of the CNC film has been demonstrated owing to its low solar light absorption and high mid-infrared (MIR) emissivity at the atmospheric transmission window (8–13 μm). The CNC film can bring down the temperature of the insulated box by ∼6 <b>°</b>C kept under solar simulator illumination, suggesting an effective radiative cooler. Further, the amine functionalization of CNC has resulted in a remarkable increase in current and mobility, improving the film’s conductivity by several folds. The photoresponsivity of the RhB-encapsulated-amine-functionalized CNC photodetector shows a peak response of ∼6.3 mA/W at ∼665 nm under zero bias. The external quantum efficiency of fabricated devices is about 1%.

However, a significant challenge is the low gas–liquid mass transfer rates due to the limited solubility of C1 gases. This study investigates CO₂ fermentation enhancement using a high-pressure gas fermentation (HPGF) reactor embedded with electrodes, effectively overcoming CO₂ solubility barriers and addressing sustainability through an innovative approach. CO₂ fermentation with H₂ as the electron donor was conducted in pressurized fermenters (PFs) at varying partial pressures (pCO₂-2, -3, and -5 bar), while pressured electro-fermentation (PEF) used electrodes to replace H₂. The pCO₂-PEF-5 condition achieved the highest acetic acid productivity of 2.8 g/L, followed by pCO₂-PEF-3 at 2.65 g/L, representing 1.2 and 1.18 times higher yields than the best condition of PFs (pCO₂-PF-3, 2.1 g/L), respectively. Additionally, PEF systems enhanced solventogenic activity, with ethanol production reaching 1.4 g/L in pCO₂-PEF-5. The substitution of H₂ with electrodes in CO₂ fermentation improved fixation and conversion rates (pCO₂-PEF-5: 67 mg/L/h, 77%), demonstrating a viable strategy for enhanced CO₂ conversion. The thermodynamic analysis indicated more spontaneous synthesis of acetic acid and ethanol in PEF systems compared with PF systems. Bioelectrochemical assessments revealed higher charge transfer rates, with a faradaic efficiency of 48% in pCO₂-PEF-5, further supporting CO₂ conversion. Especially, key genes in the Wood–Ljungdahl pathway (WLP) were upregulated in PEF systems, confirming that electro-fermentation influences metabolic pathways favoring carbon fixation and solvent production. A life cycle assessment (LCA) highlighted a net emission reduction of −7 kg CO₂ equiv in PEF-5 and lower impact across endpoint categories, highlighting the carbon-negative potential of this approach. From a planetary boundary framework perspective, this process operates within the Holocene state by reducing CO₂ emissions, helps in maintaining biosphere integrity, reduces atmospheric CO₂, and contributes minimally to nitrogen and phosphorus flows. This study signifies the sustainability of the PEF strategy for scaling CO₂ conversion processes. The integration of electro-fermentation not only addresses mass transfer limitations but also enhances carbon fixation efficiency and metabolic productivity.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"22 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857924","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 work deeply explores glycerol dehydration to acrolein over ZSM-5 zeolite catalysts with various pore structures and aluminum distributions. The results reveal that glycerol conversion is enhanced through the construction of a mesoporous structure and the increase in Brønsted acid sites of the catalysts, but acrolein selectivity is not directly related to these factors. Further characterizations, density functional theory calculation, kinetic study, and reaction mechanism analysis demonstrate that the richest Al_single sites in the zeolite framework and the least Al_pair sites in the straight and sinusoidal channels can prevent the generated acrolein from adsorbing on adjacent Al sites. This allows acrolein to immediately escape from the catalyst surface, reducing side reactions and enhancing its selectivity. Therefore, the synergistic between the mesoporous structure and more Al_single sites in the ZSM-5 zeolite framework promotes acrolein yield. Additionally, a descriptor φ, reflecting the amount of Al_single sites and the external specific surface area of the ZSM-5 zeolite, is first proposed to more clearly elucidate the structure–performance relationship. This study provides a new perspective for understanding the mechanism of catalytic dehydration of glycerol to acrolein, guiding the development of highly efficient catalysts.
