Thermoelectric textiles have garnered significant attention in energy harvesting and temperature sensing due to their comfort and reliable long-term power generation capabilities. However, existing thermoelectric textiles rarely realize antibacterial, high output performance, and sensing capabilities simultaneously. Here, we present a facile and scalable method for fabricating n-type silver selenide (Ag2Se) cotton threads with exceptional antibacterial, high power output, and advanced sensing capabilities. The Ag–Ag2Se segmented structures are prepared using the segmented selenization method. Subsequently, a thermoelectric textile consisting of 50 pairs of p–n legs is fabricated, which can generate a power density of 500 μW m–2 at a temperature difference of 30 K, and it can provide an output voltage of 24.7 mV when worn on the arm at room temperature. The textile-based sensor exhibits temperature detection (0.7 K) and a response time (2.49 s). Integrating Ag2Se cotton threads onto textiles enables the utilization of multipixel touchpads for writing and communication. Additionally, these sensors can be incorporated into gloves to accurately detect the surrounding objects’ temperatures. This thermoelectric cotton thread not only facilitates energy harvesting but also establishes a solid foundation for widespread application in multifunctional textile electronics.

Controlling the morphology of metal–organic frameworks (MOFs) is critical for tailoring their transformation into metal oxides with unique microstructures and properties, particularly for gas sensing applications. In this study, a dual In-MOF-MF was developed using a mixed linker approach involving terephthalic acid and fumaric acid. These two linkers interact with In 3 + ions to produce nanofibers with a high aspect ratio. The resulting In 2 O 3 -MF exhibits superior acetone sensing properties compared to In 2 O 3 derived from single-linker MOFs. Furthermore, the n-type In 2 O 3 -MF was coupled with p-type PtO to create a p-n junction gas sensor. The combination of rich active sites and the well-defined coupling interfaces between PtO and In 2 O 3 -MF leads to remarkable acetone sensing performance, featuring a high response (347–100 ppm acetone), rapid response/recovery time (34/18 s), excellent selectivity, and a relatively low detection limit (300 ppb). This work highlights a mixed-linker strategy for MOF morphology manipulation, enabling the fabrication of a one-dimensional p-n junction for next-generation advanced acetone sensing applications.

As a mainstream commercial cathode material for lithium-ion batteries (LIBs), LiFePO4 (LFP) is still limited by its inherently low electronic conductivity and slow diffusion kinetics. Therefore, a unique and innovative synthesis strategy must be devised to overcome these deficiencies. Hereby, we successfully synthesized N,F co-doped carbon encapsulated hollow LFP nanoshuttles (LFP-NFC) using an iron-based metal–organic framework (Fe-MOF) as the precursor. Benefitting from the hollow and porous structure derived from Fe-MOF, as-synthesized LFP-NFC effectively shortens the lithium-ion diffusion path and accelerates the ion diffusion speed. Moreover, the carbon layer doped with N and F heteroatoms induces more active sites for lithium storage and improves the electronic conductivity. The optimized LFP-NFC exhibits excellent electrochemical performance with a specific discharge capacity of 162.74 mAh g–1 at 0.1 C and a superior rate capability (102 mAh g–1 even at 10 C).

Exploring efficient and durable methanol oxidation reaction (MOR) electrocatalysts is crucial for the industrialization of direct methanol fuel cells. Herein, we designed MOR electrocatalyst of PtRu/Ni-N-C, in which PtRu nanoclusters (PtRu NCs) are loading on nitrogen-doping carbon support anchoring Ni single atoms (Ni-N-C). Compared with PtRu NCs and Pt/C, PtRu/Ni-N-C exhibits more excellent MOR activity with 2050 mA mg pt -1 and tougher anti-CO toxicity over 6000 s CA test, proving that the synergetic effect of nanoclusters and single atoms support enhance MOR activity and resistance to anti-CO toxicity. The fine spectroscopy analysis and density functional theory (DFT) calculations demonstrate that the strong metal-support interaction (SMSI) between nanoclusters and single atoms, facilitating the electron transfer of about 0.4 e from PtRu NCs to the Ni-N-C support, effectively reduces the d -band center of Pt to weaken the adsorption capacity of *CO and *COOH intermediates. Moreover, the synergistic sites derived PtRu NCs coupling Ni single atoms accelerate *OH adsorption, promoting the adjacent *CO removal. This work offers deep insight into the SMSI effect between nanoclusters and single atoms support to design the efficient Pt-based MOR electrocatalysts.

A series of Andricin B derivatives were designed and synthesized using fatty acid modification at N-terminus of the antimicrobial peptides. The hydrophobicity of Andricin B was altered through fatty acid modification, and the bioactivity was investigated. The interaction between Andricin B and its derivatives with DNA was measured using multi-spectroscopy. Spectroscopic analysis revealed that Andricin B and its derivatives can interact with ct-DNA and G-quadruplexes DNA, and the interaction related with the length of fatty acid chain. Antimicrobial activity tests showed a significant increase using peptides with 8–10 carbons fatty acid chain. C10-Andricin B exhibited the highest antimicrobial activity, with up to a 16-fold enhancement compared to the original peptide Andricin B. Meanwhile, the protease hydrolysis stability test showed that fatty acid modification improved the stability of Andricin B against protease. Scanning electron microscopy results distinctly showed that C8-Andricin B could rupture the cell wall of bacteria. All results indicated that fatty acid modification peptides are an effective strategy for enhancing activity and stability of antimicrobial peptides. This research provides valuable insights for further research on antimicrobial peptides.

The development of efficient and stable bifunctional non-noble metal catalysts for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is essential for electrochemical water splitting. In this study, CoNi@C core–shell structure catalysts derived from ZIF-67 were synthesized through high-temperature calcination. The hydrophilic carbon shell inhibits the oxidation of Co and Ni and enhances the activity and stability of the water splitting reaction. CoNi serves as the active site of the reaction, while the doped nitrogen further promotes the electrocatalytic reaction. The synthesized Ni1Co10/C catalyst exhibits high bifunctional performance, with low overpotentials at 100 mA cm−2 for the OER (380 mV) and HER (357 mV), and a high double-layer capacitance (54 mF cm−2). Moreover, the Ni1Co10/C catalyst serves as an effective cathode for water splitting in a two-electrode system, demonstrating a stable cell voltage of 2.05 V and maintaining a constant catalytic current of 100 mA cm−2 over 24 hours. DFT calculation showed that the active site of the OER and HER was Co.

In this paper, ZnS/NiO p-n heterojunction microspheres were fabricated via a two-step hydrothermal approach. The sensing properties of composites with different ZnS contents were investigated by regulating the ratio of Zn. When containing 25 mol% ZnS, the ZnS/NiO nanosphere sensor achieved a response of 125. The response was improved by a factor of about 83.3 compared to pure NiO. The sensor functions optimally at a temperature of 225 ℃, and it possesses excellent selectivity, a rapid response/recovery time (49/44 s), and long-term stability. Therefore, this paper provides a hydrothermal method to prepare ZnS/NiO nanocomposites with heterojunction, specifically designed to detect n-butanol. After performing a series of characterizations, it was determined that the enhancement of the gas-sensitive properties could be related to the construction of ZnS/NiO heterojunctions and the increase in oxygen vacancies.

A novel N -halamine terpolymer, i.e. , P(ADMH-MMA-HEMA)-Cl, with high antibacterial efficacies were fabricated via a free-radical copolymerization of 3-allyl-5,5-dimethylhydantoin(ADMH), methyl methacrylate(MMA), and hydroxyethyl methacrylate (HEMA), followed by a chlorination treatment using sodium hypochlorite as chlorinating agent. A controllable synthesis of P(ADMH-MMA-HEMA)-Cl was achieved by tuning chlorination conditions, such as chlorination temperature, reactant concentration, chlorination time, etc . A series of antibacterial assays were conducted, and the as-prepared products P(ADMH-MMA-HEMA)-Cl showed good killing capabilities against both Gram-positive and Gram negative bacteria. Remarkably, compared to N -halamine biopolymer counterparts, e.g. , P(ADMH-HEMA)-Cl and P(ADMH-MMA)-Cl, and the as-prepared N -halamine terpolymer P(ADMH-MMA-HEMA)-Cl presented the enhancement in antibacterial efficiency toward pathogens. It is believed that this approach offers great potential to be utilized in various fields where antibacterial properties are highly required.

Urea generation through electrochemical CO 2 and NO 3 − co-reduction reaction (CO 2 NO 3 RR) is still limited by either the low selectivity or yield rate of urea. Herein, we report copper carbonate hydroxide (Cu 2 (OH) 2 CO 3 ) as an efficient CO 2 NO 3 RR electrocatalyst with an impressive urea Faradaic efficiency of 45.2% ± 2.1% and a high yield rate of 1564.5 ± 145.2 μg h −1 mg cat −1 . More importantly, H 2 evolution is fully inhibited on this electrocatalyst over a wide potential range between −0.3 and −0.8 V versus reversible hydrogen electrode. Our thermodynamic simulation reveals that the first C-N coupling follows a unique pathway on Cu 2 (OH) 2 CO 3 by combining the two intermediates, *COOH and *NHO. This work demonstrates that high selectivity and yield rate of urea can be simultaneously achieved on simple Cu-based electrocatalysts in CO 2 NO 3 RR, and provide guidance for rational design of more advanced catalysts.

The development of efficient and stable composite photocatalysts is crucial for advancing the field of photocatalytic hydrogen production. In this paper, the Co 0.5 CuP/Cd 0.9 Co 0.1 S composite photocatalyst was synthesized by the template etching method and the in-situ growth method. The Co 0.5 CuP was tightly anchored on the surface of hollow structure Cd 0.9 Co 0.1 S nanospheres. The hydrogen production efficiency of the Co 0.5 CuP/Cd 0.9 Co 0.1 S composite photocatalyst was enhanced by adjusting the doping proportion of cobalt and the loading quantity of Co 0.5 CuP. Meanwhile, a p-n heterojunction was formed between Co 0.5 CuP and Cd 0.9 Co 0.1 S, which enhanced the separation of photoinduced charge carriers and further boosted the efficiency of photocatalytic hydrogen production. The results showed that the photocatalytic hydrogen evolution efficiency of Co 0.5 CuP/Cd 0.9 Co 0.1 S could reach 9.64 mmol·g −1 ·h −1 . In addition, the photocatalytic reaction mechanism of the Co 0.5 CuP/Cd 0.9 Co 0.1 S composite photocatalyst was inferred based on the photoelectrochemical test and density functional theory calculation. This approach pioneers a novel pathway for the preparation of heterojunction photocatalysts by the combination of transition metal phosphide and hollow multi-metal sulfides.

Glucocorticoids possess extensive and potent pharmacological effects, but their misuse and overuse are widespread concerns. Consequently, the environmental pollution and health hazards associated with their excessive usage cannot be overlooked. There is an urgent need for enhanced removal and a thorough understanding of the environmental and safety risks arising from the overconsumption of these drugs. In this study, a novel F, N-enriched covalent organic framework (designated as TAPT-COF) with high crystallinity was synthesized. TAPT-COF features numerous active sites, including F-F interaction and hydrogen bond interaction sites, along with a high specific surface area and good thermal stability. These characteristics enable TAPT-COF to serve as an advanced adsorbent for dispersed solid-phase extraction (D-SPE) of glucocorticoids such as fluocinonide acetate, budesonide, and dexamethasone, with adsorption capacities ranging from 146.77 to 228.90 mg·g⁻¹ . Notably, TAPT-COF exhibits exceptional protein exclusion efficiency, achieving exclusion rates exceeding 95 %. Due to these advantages, TAPT-COF based D-SPE demonstrates strong applicability in the analysis of complex practical samples, including water and plasma, with satisfactory recoveries ranging from 76.48 % to 112.76 %. Compared to a COF (TPB-COF) that lacks a triazine group, TAPT-COF exhibits superior adsorption performance for target glucocorticoids. This is attributed to its ability to provide enhanced electrostatic interactions, as well as the synergistic effects of hydrogen bonding and F-F interactions. Additionally, TAPT-COF displays a low hemolytic activity, indicating its potential for in vivo analysis.

Metal fluorides confined in heteroatom-doped carbon nanostructures are viewed as one of the most promising high capacity cathodes for high-performance lithium rechargeable batteries. Herein, we present a facile in situ reaction approach to synthesize nitrogen-doped porous carbon (NPC)-confined metal fluorides, which involves in situ etching toward a Schiff-base organic precursor and fluorination of metal oxides by polytetrafluoroethylene during a one-step heating process. The afforded NPC-confined FeF3 (FeF3@NPC) facilitates fast Li+/e− diffusion kinetics, accommodates severe volume fluctuation and reduces the FeF3 cathode dissolution, thus providing an outstanding high-rate capacity of 181 mA h g−1 at 5 C, accompanied by superior cycle life within 500 cycles at 2 C. This novel approach opens up new horizons to design high-performance nanoconfined metal fluoride-based materials for sustainable energy applications.
