Fatty acid esters are building blocks in next-generation biofuels, eco-friendly detergents, crop-enhancing adjuvants, and high-value cosmetic emollients. However, their industrial production relies on two unsustainable approaches: petrochemical-derived chemical catalysis that poses sustainability challenges and botanical extraction processes that exacerbates land-use conflicts. Here we develop a de novo microbial biosynthesis platform using the non-conventional oleaginous yeast Rhodotorula toruloides as a chassis, and achieve high-level biosynthesis of structurally diversified esters without the addition of alcohol or lipid precursors. By screening specific pathway enzymes and conducting modular pathway engineering, we successfully reprogram the native lipogenic metabolism of R. toruloides for de novo synthesis of fatty acid ethyl esters (FAEEs) at 579 mg/L, fatty acid short-branched chain esters (FASBEs) at 169 mg/L, and wax esters (WEs) at 1.30 g/L in shake-flask fermentation. As a case study, we optimize the synthesis of WEs in a 5 L fermenter, and achieve a production of 13.04 g/L. These engineered strains potentially offer an efficient, economical and environmentally friendly platform for the industrial production of fatty acid esters and oleochemicals. Fatty acid esters are biofuels, eco-friendly detergents, and cosmetic emollients, however, their industrial production is unsustainable. Here the authors develop a de novo biosynthesis platform using the yeast Rhodotorula toruloides and achieve high-level production of structurally diverse esters.

Polyethylene (PE) and polypropylene (PP) are widely used in commercial lithium-ion battery (LIB) separators owing to their high mechanical strength and chemical stability. However, both polymers suffer from poor high-temperature tolerance, low porosity, and inadequate electrolyte wettability, making it difficult to reconcile electrochemical performance with safety under thermal stress. Developing advanced lithium-ion battery separators is therefore crucial for achieving high efficiency, safe LIBs. This study presents a boehmite/polyacrylonitrile (BM/PAN) composite nanofiber separator fabricated by electrospinning and systematically examines how BM loading affects separator microstructure and electrochemical behavior. Compared with commercial PP separators, the BM/PAN composites exhibit a unique three-dimensional interconnected fiber network, together with markedly improved wettability, thermal stability and electrochemical properties. The optimal formulation contains 4 wt% BM (denoted PAN-BM-4) exhibited an outstanding wettability with electrolyte uptake of 692.5% with the porosity of 80.7% and electrolyte contact angle of 25.5°, ensuring rapid electrolyte infiltration and efficient ion transport. it also displayed a higher mechanical property with tensile strength of 7.9 MPa and elongation at break of 27% (cf. 6.5 MPa and about 45% for pure PAN), indicating enhanced structural integrity. Meanwhile, such PAN-BM-4 separator demonstrates an excellent thermal stability with negligible shrinkage at 200 °C and a residual mass of 57.6% at 800 °C, effectively mitigating the thermal-runaway risk of conventional separators. Moreover, as to the electrochemical performance, this unique PAN-BM-4 separator showed an ionic conductivity of 3.31 mS/cm, more than six times that of commercial PP, and the electrochemical stability window exceeding 5.5 V (versus Li + /Li) and a Li + transference number ( t Li +) of 0.42, substantially higher than PP (0.28) and pure PAN (0.34), reflecting enhanced selective Li+ transport. Besides, in half-cell testing, the PAN-BM-4 separator delivers an initial discharge capacity of 140.6 mAh/g at 0.5 C with 88.3% capacity retention after 100 cycles. in summary, this work establishes a viable materials-design strategy and experimental framework for next-generation LiB separators that simultaneously achieve high ionic conductivity, superior thermal stability and favorable interfacial compatibility.

Purpose: Anaplastic thyroid carcinoma (ATC) is an exceptionally aggressive malignancy that, despite accounting for only 1%-1.5% of all thyroid cancers, is responsible for over half of thyroid cancer-related deaths. Characterized by limited treatment options and a poor prognosis, ATC presents a critical clinical challenge. In this study, we developed and evaluated an innovative liposomal system (T-AUF-LPs) co-loading Auranofin (AUF) and Timosaponin AIII (TAIII) aimed at inducing ferroptosis in ATC cells. Methods: T-AUF-LPs were prepared via the film-hydration method and their physicochemical properties were characterized. Cellular uptake, anti-proliferative effects, and ferroptosis-related mechanisms—including reactive oxygen species (ROS), iron levels, glutathione (GSH), GPX4, ACSL4, and NCOA4—were assessed in CAL-62 and 8505C ATC cell lines. In vivo antitumor efficacy and biosafety were evaluated using a BALB/c nude mouse xenograft model. Results: T-AUF-LPs showed superior physicochemical properties compared to conventional liposomes, including uniform spherical morphology, reduced particle size, and enhanced encapsulation efficiency. Cellular assays revealed significantly improved uptake of T-AUF-LPs in both ATC cell lines. The formulation inhibited cell proliferation in a dose-dependent manner, an effect effectively reversed by ferrostatin-1, confirming ferroptosis as the primary cell death mechanism. Mechanistic investigations indicated that T-AUF-LPs treatment increased intracellular ROS and iron levels, depleted GSH, and induced upregulation of ACSL4 and NCOA4 along with downregulation of GPX4. In vivo evaluation demonstrated effective tumor growth suppression with an excellent safety profile and no significant organ toxicity. Conclusion: T-AUF-LPs exert potent anti-tumor effects by inducing ferroptosis without causing systemic organ toxicity. They represent a promising therapeutic strategy for ATC, thereby addressing a critical unmet need in the management of this disease.

This research paper tackles the cross-sensitivity problem commonly encountered in metal oxide semiconductor gas sensors by suggesting a heterojunction structure to improve their overall gas-sensing performance. Pure-phase In 2 O 3 nanocubes and In 2 O 3 /SnO 2 heterojunction composites were effectively synthesized via a one-pot hydrothermal method, and their sensing properties towards formaldehyde gas were systematically investigated. The experimental findings indicate that, in comparison with the pure In 2 O 3 sensor, the In 2 O 3 /SnO 2 heterojunction sensor displays significantly higher response values to formaldehyde at the same operating temperature, along with more rapid response and recovery rates. Additionally, this heterojunction sensor demonstrates excellent selectivity for formaldehyde, retaining its high selectivity even in the presence of various interfering gases. This study offers a feasible approach for the development of highly sensitive, selective, and rapidly responsive formaldehyde gas sensors, and provides a valuable reference for the progress of gas sensor technology.

Next-generation optical wireless communication requires photodetectors that offer both high spectral selectivity and strong security against interception. However, conventional broadband devices remain vulnerable to spectral crosstalk and eavesdropping. Here we show a digitally encoded dual-narrowband organic photodetector that intrinsically integrates optical filtering with algorithm-assisted encryption to enable secure, high-fidelity optical wireless communication. Operating without an external power supply, the self-powered device employs a Fabry-Pérot cavity with a carefully designed organic spacer Liq to achieve selective detection at wavelengths of 485 nm and 910 nm, along with an ultrafast response time of 440 ns. By combining chaotic encryption with hardware-level wavelength selectivity, our hardware–software co-design system achieves an ultra-low bit-error rate of 9.17 × 10 −5 at 1.25 Mbps while demonstrating strong resilience to eavesdropping and external interference. Furthermore, precise cavity engineering allows the dual-narrowband response to be extended into the short-wave infrared region (>1230 nm), offering a scalable route toward multi-wavelength secure transmission, high-resolution spectroscopy, and intelligent photonic networks.

Replacing the oxygen evolution reaction with the electrocatalytic oxidation of glycerol to formic acid offers an attractive route for value-added chemical production. Spinel-type oxides, recognized for their favorable electronic structures, are active for GOR; however, monometallic spinels typically exhibit suboptimal performance due to insufficient substrate enrichment at the catalyst interface. In this study, a three-dimensional heterojunction catalyst (CoFe 2 O 4 /MnCo 2 O 4 ) was grown on nickel foam via a simple hydrothermal and calcination method. The CoFe 2 O 4 /MnCo 2 O 4 heterojunction exhibits outstanding electrocatalytic performance toward direct glycerol oxidation, achieving a Faradaic efficiency for formic acid of up to 90% and a low potential of only 1.299 V vs. RHE at a current density of 100 mA·cm −2 . Moreover, the GOR exhibits a 200 mV lower potential at 200 mA·cm −2 compared to the oxygen evolution reaction (OER), substantially reducing the reaction voltage and energy consumption. The interfacial synergy within the heterojunction facilitates efficient charge transfer, enhances the adsorption of glycerol, and lowers the reaction overpotential, thereby accelerating the overall reaction kinetics. This work not only enables the selective synthesis of high-value chemicals but also offers an in-depth analysis of the catalyst's structure–performance relationship, paving a new avenue for the rational design of highly efficient heterogeneous catalysts. Graphical The spinel heterojunction creates a synergistic effect that enhances reactant adsorption, facilitates charge transfer, and lowers the overpotential, resulting in highly selective formic acid production with 90% Faradaic efficiency and significantly reduced energy consumption compared to OER.

To resolve the insufficient thermal conductivity (TC) of traditional epoxy resin (EP) potting compounds in high-power-density electric vehicle drive motors, this study employed a hydrogen-bonded self-assembly strategy to prepare Diamond-Boron Nitride (ND-BN) heterostructure fillers with varying BN particle sizes (5, 20, 30 μm). The ND-BN/EP composites were fabricated with a fixed filler content of 20 wt.% and an ND:BN ratio of 1:2. The TC and dielectric properties of ND-BN/EP composites were investigated and compared with BN/EP composites. The characterization results confirm the successful attachment of ND particles onto the BN sheet surfaces and the formation of hydrogen bonds between them. The heterostructure filler exhibits good dispersion within the EP matrix. When the BN particle size was 20 μm, the ND-BN/EP composite achieves an optimal thermal conductivity of 1.3 W·m⁻ 1 ·K⁻ 1 . Smaller BN particles struggle to form continuous thermal pathways, while larger BN particles tend to stack, hindering heat transfer. Smaller filler particles exhibit stronger interfacial polarization, leading to increased dielectric constants and dielectric loss tangent. Concurrently, the number of interfacial defects increased, introducing more localized electric field concentration points and consequently reducing the breakdown electric field strength. The filler size has little effect on the volume resistivity of the composites. This study clarified the regulatory mechanism of heterostructure filler size factors on the TC and dielectric properties of EP composites, providing a theoretical basis for the development of highly thermally conductive and insulating EP potting compounds.

Widespread adoption of electrolytic water splitting for hydrogen production is limited by the high overpotential and slow kinetics of the oxygen evolution reaction. This work presents a bifunctional electrocatalyst of cobalt phosphide-doped porous carbon electrocatalyst (CoP/Co 2 P/C). The catalyst was synthesized via direct pyrolysis of a composite precursor (denoted as Co/Zn-PO@Co-MOF), which consisted of spherical cobalt/zinc phosphate (Co/Zn-PO) coated with Co-based metal-organic framework. The spherical Co/Zn-PO served as a novel and safer phosphorus source, eliminating the need for conventional NaH 2 PO 2 carbonization which releases toxic gases. Although minimally incorporated into the composite precursor, Ni 2+ played two key roles: it primarily functioned to assist the coordination of Co 2+ with 2-methylimidazole on the surface of Co/Zn-PO, and additionally modulated the resulting CoP/Co 2 P ratio. Moreover, the carbonization temperature was a critical variable in converting Co/Zn-PO@Co-MOF into CoP/Co 2 P and affected the final ratio between them. Based on the interfacial synergistic effect between CoP and Co 2 P, along with three catalytic active sites of Co, P and Pyridinic N, the optimized CoP/Co 2 P/C achieved a current density of 10 mA cm − 2 at low overpotentials (η 10 ) of 204 mV for HER and 339 mV for OER. The performance of CoP/Co 2 P/C remains comparable to that of most recently reported cobalt phosphide-based catalysts. Graphical The alternative text for this image may have been generated using AI.

Research on the treatment of biomass using organic solvent fractionation technology has made significant progress, but the dissolution behavior of the three components (cellulose, hemicellulose, and lignin) during pretreatment has not yet been systematically summarized. In this study, corn cob was used as the raw material, and the full range of ethanol/water pretreatment system was employed to systematically investigate the effect of solvent ratio on the dissolution of the three components under self-catalytic conditions and different process conditions such as reaction temperature, time, and solid–liquid ratio. Furthermore, XRD, FTIR and solid-state UV were used to analyze the structural changes of the components during the dissolution process. Based on these, the alternating extraction of water and ethanol on the raw material and solid residue were used to infer the effect of ethanol and water in the pre-treatment. The results showed that the increase in ethanol ratio could inhibit the dissolution of polysaccharides but promote the removal of lignin, which were consistent with the existing conclusions.Based on the extraction results, we speculated that water was the key factor in breaking the connection bonds between hemicellulose and lignin and promoting the dissolution of hemicellulose; ethanol was responsible for the dissolution of lignin, but the bond breaking still required the participation of water. This extraction method provided a new idea for revealing the mechanism of action of the solvent in the pre-treatment of organic solvents and provided data support for the separation of the three components in biomass.

Water scarcity and water pollution are two major environmental issues facing all over the world. Membrane technology is an efficient and advanced wastewater treatment technology that has unique advantages in removing particulate matter, organic matter, microorganisms, and other pollutants. The present work report a high performance nanofiltration membrane for recycling and utilization of energy resources. The membrane was prepared by co-deposition dopamine and PEI in the PES based membrane as the intermediate layer, then spraying with different content of MOF-801. Subsequently, interfacial polymerization was carried out through piperazine and 1,3,5-benzenetricarbonyl trichloride. The obtained membrane was evaluated by testing the separation performance of Na 2 SO 4 , MgSO 4 , MgCl 2 and NaCl aqueous solution. FTIR, CA, XPS, SEM, AFM were carried out to analysis the physical and chemical structures of membranes. The effects of dopamine co deposition, nanomaterial content, salt type, stability and anti-pollution were investigated. Results shown that the membrane exhibits excellent water flux and rejection after modified with MOF-801. The addition of 2% nanofiller could achieve the optimum performance.

A new method is developed to synthesize Au/Ag alloy nanoparticles (Au/Ag-NPs). The obtained Au/Ag-NPs are further dispersed in polyvinyl alcohol (PVA) solution to construct Au/Ag hydrogel surface enhanced Raman scattering (SERS) chips through a simple Ca 2+ -mediated aggregation of Au/Ag-NPs and a physical crosslinking of PVA. The formed aggregated Au/Ag-NPs (a-Au/Ag-NPs) show a strong localized surface plasmon resonance corresponding to the commonly used 532 nm laser. Therefore, under the action of 532 nm laser, the abundant nanogaps contained in the a-Au/Ag-NPs turn to high active electromagnetic “hot spots”, providing strong electromagnetic enhancement (EM). Moreover, Au/Ag-NPs provide a moderate Fermi level of -4.72 eV, which facilitates its photo-induced charge transfer with many molecules under 532 nm laser irradiation, resulting in the chemical enhancement (CM) effect. The synergistic effect of EM and CM leads to ultrahigh SERS activity. Additionally, the unique structure of hydrogel provides excellent signal uniformity and robust anti-interference ability. Thus, the obtained Au/Ag hydrogel SERS chips are ideal SERS platform for the quantitative determination of many molecules. For instance, a sensitive and reliable SERS method is established for the simultaneous detection of methyl parathion and triazophos in fruits and tea.

To overcome the intrinsic limitations of TiO 2 , specifically its wide band gap and rapid photogenerated carrier recombination, for dyeing wastewater treatment, a Yb 3+ /Er 3+ co-doped TiO 2 -ZnO heterostructure was fabricated by sol–gel method. X-ray diffraction revealed inhibited anatase-to-rutile phase transition. X-ray photoelectron spectroscopy confirmed Ti 2p binding energy shifts, indicating strong electronic interactions between dopants and the host lattice. Ultraviolet–visible diffuse reflectance spectroscopy showed band gap narrowing to 2.927 eV, with upconversion effect extending light absorption to the near-infrared region. Photoluminescence measurements demonstrated suppressed carrier recombination, and XPS confirmed abundant oxygen vacancies. The optimal sample achieved 74.31% methylene blue degradation under visible light for 6 h and 98.58% under ultraviolet light for 2 h, outperforming commercial P25. The Yb 3+ /Er 3+ co-dopants serve dual functions: they act as upconversion centers to harvest low-energy photons and function as electronic modulators that induce Ti 2p binding energy shifts and create oxygen vacancies, thereby enhancing charge separation and surface reactivity. This work integrates rare-earth co-doping with heterojunction engineering to boost TiO 2 photocatalysis.
