Traditional high-temperature thermal desorption and unactivated advanced oxidation process (AOP) are either energy-intensive or inefficient due to slow pollutant degradation. This study presented an innovative and effective remediation approach for BaA contaminated soil by combining low-temperature thermal desorption with AOP. The combined method utilizes heat from low-temperature thermal desorption to activate sodium persulfate, thereby enhancing BaA degradation. The results demonstrated that the combined low-temperature thermal desorption and AOP achieved an impressive BaA removal efficiency of up to 92.7 % at 60 °C and 90 °C, surpassing the efficiency of individual treatments. The primary reactive oxygen species responsible for BaA degradation were identified as sulfate radicals and hydroxyl radicals with both contributing nearly equally to the process. The study identified the intermediates formed during BaA degradation and proposed a degradation pathway. The intermediates had lower boiling points and reduced toxicity compared to BaA, indicating the mineralization process was effective in reducing environmental risks. Additionally, the addition of 3 mL methanol improved BaA removal efficiency to 62.2 % from 41.9 % in the control group without methanol, indicating the addition of methanol in AOP significantly improved BaA removal by enhancing desorption from soil particles. This research underscores the potential of the combined low-temperature thermal desorption and AOP as a sustainable, energy-efficient, and cost-effective remediation technology for soils contaminated with polycyclic aromatic hydrocarbons, offering a promising solution for soil remediation.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"72 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the stable operation for SMBs at − 40 °C with carbonate ester-based electrolyte remains a tremendous challenge owing to sluggish kinetic of Na+ desolvation and Na+ migration through solid electrolyte interphase (SEI). Hence, we construct stable operation of ultralow-temperature SMBs at − 40 °C via a weakly anion-drived solvation of carbonate-ester electrolyte with low concentration, which endows high Na+ conductivity and low Na+ desolvation barrier. Anion-driven solvation is favor of forming a roust Na+-conductive NaF-rich SEI film, thereby stabilizing SMBs at low temperature. As a result, symmetrical cells achieve long cyclic stability for 1000 h at − 20 °C. In addition, the SMBs matching the P2-type Na0.75Ni0.34Mn0.66O2 (NNMO) cathode with an electrochemical window of 4.15 V achieve the high capacity retention of 91.5 % after 600 cycles at − 20 °C and 85.4 % after 160 cycles at − 40 °C. Moreover, pouch cell with high energy density (227.4W h kg−1) and high-loading cathode (11.76mg cm−2) provides a stable 100 cycle at − 20 °C. The optimized carbonate ester electrolyte provides vital insights into developing ultra-low-temperature SMBs.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"19 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we constructed a novel self-powered PEC biosensor based on BiVO4/Bi0.95Nd0.05FeO3 (BVO/BNFO) semiconductor-ferroelectric heterojunction photoelectrode for detecting carcinoembryonic antigen (CEA). Firstly, the doping of rare earth Nd3+ effectively suppressed the oxygen vacancy content and Fe3+/Fe2+ valence state changes, greatly improving the ferroelectric properties of BiFeO3. Compared with BiVO4 (BVO) and BiVO4/BiFeO3 (BVO/BFO), BVO/BNFO photoelectrodes increased the photocurrent without external bias by 13.15 times and 2.23 times, respectively, through synergistic ferroelectric polarization and built-in electric field. Furthermore, the interfacial energy band bending and charge transfer of BVO/BNFO could be effectively modulated by controlling the polarization state, thereby resulting in a 203.9 % enhancement in photocurrent under positive poling, and maintaining excellent stability under long-term illumination. As a result, the self-powered PEC biosensor demonstrated a wide detection range for CEA with concentrations ranging from 1 pg/mL to 0.1 mg/mL, as well as a low detection limit of 1.91 pg/mL. Benefiting from its excellent stability and high selectivity of constructed PEC biosensors, we believe this innovative amplification strategy employing ferroelectric polarization may offer new opportunities for clinical diagnosis of CEA and other tumor markers.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"131 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143736516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The catalytic mechanism and active sites in STC-H2-FeSi2 system were further studied through DFT calculations. The calculated results confirm that FeSi2 was the catalytic active sites, and transformed into FeSi during the reaction. A kinetic model based on the L-H mechanism was established, indicating that adsorption of STC on FeSiy was the rate-determining step with the activation energy of 100.47 kJ/mol and the adsorption heat of H2 and TCS of −76.33 and −31.70 kJ/mol, respectively.

The optimized sample exhibits a threefold increase in electrical conductivity, while its Seebeck coefficient remains unchanged. Owing to the decoupling of electrical conductivity and Seebeck coefficient, the optimization achieves a remarkable enhancement in average zT, ranging from 0.6 to 1.05, and a very competitive peak zT of 1.65 at 823 K. Besides the reached high thermoelectric performance, this study also demonstrates a unique and highly promising strategy for thermoelectric materials.

Herein, we present a simple and scalable method for fabricating biomass-derived conductive elastomers using α-lipoic acid as the primary structural building block, coupled with mild heating and UV irradiation. This dual-step process facilitates molecular reorganization and network optimization, yielding an elastomer with excellent mechanical resilience, sensing performance, and hydrophobic properties. The engineered elastomer exhibits a remarkable elongation at break of up to 700 % and maintains an elasticity recovery of 87 % under repeated large-strain cycles. Even in the presence of notches, it retains 72 % of its original elongation at break, demonstrating outstanding durability. Its unique molecular structure and hydrophobic properties afford strong adhesion to various solid substrates, with underwater adhesion strengths reaching up to 3.0 MPa, alongside remarkable stability in extreme pH and saline environments. Moreover, the elastomer exhibits excellent conductivity and dual-environment sensing capabilities, enabling precise and real-time detection of deformations, body motion, and temperature changes in both air and underwater conditions.

Herein, we report a safer, oxygen-free synthetic route for high-quality InP QDs by combining tri(dimethylamino)phosphine [(DMA)3P] (as the phosphorus source) and ZnF2 as an additive in an alkylamine solvent. ZnF2 in situ produces HF, which suppresses the formation of polyphosphates (P2O7x−) and mixed oxides (InPOx) and enables the growth of high-quality QDs. Subsequent growth of ZnSe/ZnS shells result in core/shell/shell QDs with enhanced photoluminescence quantum yield (PLQY) of 93% and 88% for red and green-emitting QDs. We report, as a result, red and green light-emitting diodes (LEDs) with external quantum efficiencies (EQEs) of 11.8% and 7.5%, respectively.
