In this study,a string of Cr-Mnco-modified activated coke catalysts(XCryMn1-y/AC)were prepared to investigate toluene and Hg^(0) removal *** characterizations including XRD,TEM,SEM,in situ DRIFTS,BET,XPS and H_(2)-TPR showed that 4%Cr0.5Mn0.5/AC had excellent physicochemical properties and exhibited the best toluene and Hg^(0) removal efficiency at 200℃.By varying the experimental gas components and conditions,it was found that too large weight hourly space velocity would reduce the removal efficiency of toluene and Hg^(0).Although O_(2) promoted the abatement of toluene and Hg^(0),the inhibitory role of H_(2)O and SO_(2) offset the promoting effect of O_(2) to some *** significantly inhibited Hg^(0) removal,resulting from that toluene was present at concentrations orders of magnitude greater than mercury’s or the catalyst was more prone to adsorb toluene,while Hg^(0) almost exerted non-existent influence on toluene *** mechanistic analysis showed that the forms of toluene and Hg^(0) removal included both adsorption and oxidation,where the high-valent metal cations and oxygen vacancy clusters promoted the redox cycle of Cr^(3+)+Mn^(3+)/Mn^(4+)+Cr^(6+)+Mn^(2+),which facilitated the conversion and replenishment of reactive oxygen species in the oxidation process,and even the CrMn_(1.5)O_(4) spinel structure could provide a larger catalytic interface,thus enhancing the adsorption/oxidation of toluene and Hg^(0).Therefore,its excellent physicochemical properties make it a costeffective potential industrial catalyst with outstanding synergistic toluene and Hg^(0) removal performance and preeminent resistance to H_(2)O and SO_(2).

The Li-CO2battery has been highly rated as an intriguing technique for balancing the carbon cycle for years, but it is still significantly challenged by the obstacles such as limited reversibility, sluggish kinetics,and poor energy efficiency. Hence, the design and development of advance catalysts that can enhance the kinetics and reversibility of the CO2electrochemical cycling reactions are considered the imperative tasks. Transition metal-based catalysts are widely considered appealing owing to their unfilled dorbitals, rich and adjustable valences, as well as processibility. In this review, the working mechanism and the key issues of the CO2electrochemical cycling reaction are discussed first. Then the strategies for composition and structure design of different type of transition metal-based catalysts are highlighted,including their benefits, limitations, and the ways to implement these strategies. Finally, based on the pioneering research, the perspectives on the challenges and key points for the future development of cathode catalyst are proposed.

Community integrated energy systems (CIES) play a crucial role in promoting energy sustainability and community economic development. However, the current community demand response (DR) management measures have not fully stimulated the enthusiasm of various users to participate. Therefore, this study proposes a two-stage energy retail package design scheme for DR management in CIES. In the first stage, consumers are segmented through a classification method based on the degree of DR in their energy usage behavior. In the second stage, a multi-objective optimization strategy is employed to design energy retail packages that meet consumer needs while ensuring the interests of the community operators (CO). The simulation results verify that this approach not only enhances the stability of the system but also maximizes the benefits for both CO and consumers. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

A device capable of producing electricity from wastewater treatment process is highly desirable as it addresses critical challenges in sustainable energy generation and environmental conservation. In this work, a highly efficient three-dimensional (3D) porous network structured In2O3/ZnO/FTO photoanode and a flower-like Cu2O/CuO/Cu cathode were successfully fabricated and integrated into a visible light-driven photocatalytic fuel cell (PFC) system. Material characterization revealed that In2O3 was well-dispersed on the 3D porous ZnO network, proving ample active sites for photoelectrocatalysis. The PFC utilizing mariculture effluent containing chlortetracycline hydrochloride (CTCH) as a fuel source, achieved an open-circuit voltage of 559 mV and a maximum power density of 0.3084 μW cm−2 under visible light irradiation. Furthermore, the system demonstrated a CTCH removal efficiency of 91.5 %, outperforming ZnO/FTO and In2O3/FTO electrodes in terms of degradation efficacy and energy conversion. Additionally, the cell demonstrated outstanding recyclability and remarkable antimicrobial efficacy against Escherichia coli and Bacillus cereus, underscoring its superior functionality. The boosted photoelectrocatalytic activity was credited to the formation of the In2O3/ZnO/FTO heterojunction within the porous network-structure, which provided a high specific surface area and favorable optical and electronic traits and thereby, improving the overall efficiency of the dual photoelectrode system. This PFC device facilitates simultaneous electricity generation, pollutant degradation and bacterial sterilization, offering promising multifunction applications. © 2025 Hydrogen energy Publications LLC

Designing ceramic fuel cells (CFCs) with fast ionic conduction and superior electrochemical performance at low temperatures is critical for advancing hydrogen applications. Here, we developed a heterostructure electrolyte by combining the ionic conductor Gd0.1Ce0.9O2 (GDC) with the semiconductor material CaTiO3 (CTO) to shape into the composite heterostructure (semiconductor ionic heterostructure) CTO-GDC. The designed heterostructure with different fermi levels established the depletion zone due to the redistribution of charges at the interface, leading to enhancement of the ionic conduction;meanwhile, the established built-in electric field suppresses the electronic conduction speed of the ion's transportation at the interface of the constructed heterostructure (CTO-GDC). The formation of heterostructure introduces a number of oxygen vacancies, as confirmed via x-ray photoelectron spectroscopy (XPS) and electron paramagnetic resonance (EPR), benefiting the transportation of ions in the composite heterostructure. The prepared composite heterostructure shows the highest power output of 810 mW/cm2 at a low operational temperature of 520 °C. The CTO-GDC shows high ionic conductivity of 0.17 S cm−1 at 520 °C and low activation energy of 0.785 eV at 520-420 °C. The composite containing a 50 % molar ratio of GDC and CTO demonstrated exceptional performance by successfully inhibiting electron transit, improving ionic conductivity, and achieving outstanding power output. The enhanced ionic conductivity with low activation energy of composite heterostructure suggests that designing a heterostructure seems an efficient approach to fuel cell application. © 2025

Metformin has been demonstrated to attenuate hyperglycaemia by modulating the gut microbiota. However, the mechanisms through which the microbiome mediates metformin monotherapy failure (MMF) are unclear. Herein, in a prospective clinical cohort study of newly diagnosed type 2 diabetes mellitus (T2DM) patients treated with metformin monotherapy, metagenomic sequencing of faecal samples revealed that Phocaeicola vulgatus abundance was approximately 12 times higher in nonresponders than in responders. P. vulgatus rapidly hydrolysed taurine-conjugated bile acids, leading to ceramide accumulation and reversing the improvements in glucose intolerance conferred by metformin in high-fat diet-fed mice. Interestingly, C22:0 ceramide bound to mitochondrial fission factor to induce mitochondrial fragmentation and impair hepatic oxidative phosphorylation in P. vulgatus-colonized hyperglycaemic mice, which could be exacerbated by metformin. This work suggests that metformin may be unsuitable for P. vulgatus-rich T2DM patients and that clinicians should be aware of metformin toxicity to mitochondria. Suppressing P. vulgatus growth with cefaclor or improving mitochondrial function using adenosylcobalamin may represent simple, safe, effective therapeutic strategies for addressing MMF. © 2025 The Authors

Glycosylation is commonly used to improve the solubility and functionality of egg white protein (EWP), but glycosylated EWP is prone to quality deterioration during storage. To enhance its storage stability, cysteine (Cys) addition and dialysis desugar treatment were applied to xylo-oligosaccharide (XOS) glycosylated EWP (GEW) in accelerated storage examinations. Both Cys addition and dialysis minimized changes in soluble protein content, color difference, and particle size during storage. Further, they inhibited the Maillard reaction and the accumulation of its intermediate products. Cys addition effectively maintained protein structures and prevented protein crosslinking. However, dialysis lost the filling and protective effect of free sugars, lowering the denaturation temperature of ovalbumin. Cys and dialysis effectively maintained the stability of emulsifying properties, while cysteine better preserved gelation. Overall, both Cys addition and dialysis effectively enhanced the storage stability of GEW, with Cys proving to be more effective. © 2025, The Authors. All rights reserved.

Nonreciprocal optical devices are key components in photonic integrated circuits for light reflection blocking and routing. Most reported silicon integrated nonreciprocal optical devices to date were unit devices. To allow complex signal routing between multi-ports in photonic networks, multiport magneto-optical (MO) nonreciprocal photonic devices are desired. In this study, we report experimental demonstration of a silicon integrated 5×5 multiport nonreciprocal photonic device based on magneto-optical waveguides. By introducing different nonreciprocal phase shift effect to planar photonic waveguides, the device focuses light to different ports for both forward and backward propagation. The device shows designable nonreciprocal transmission between 5×5 ports, achieving 16 dB isolation ratio and -18 dB crosstalk. Copyright © 2025, The Authors. All rights reserved.
