Despite tremendous progress in efficiency and stability, perovskite solar cells are still facing the challenge of scalability and reproducibility. Vapor–solid reaction methods that derived from the chemical vapor deposition have been regarded as facile approaches to prepare perovskite films with large size. However, different from the precise control of compounding ratio by weighting in the solution process, the perovskite films deposited by vapor–solid reaction methods always suffer from undesired I − /Br − ratio, leading to poor performance of the solar device. Thus, controllable halogen exchange in the vapor–solid reaction process is significant for the further development of this technique. Herein, different alkali-metal ions (such as Na + , K + , and Rb + ) are added into the inorganic CsBr/PbI 2 framework, and it is found that the halogen exchange in the vapor–solid reaction process can be regulated by these ions. After optimization, high-quality Rb-Cs 0.14 FA 0.86 Pb(Br x I 1- x ) 3 films with proper I − /Br − ratio are successfully obtained. Perovskite solar cells based on the as-prepared perovskite films exhibit a significant enhancement on V oc and the champion power conversion efficiency reaches 19.6% with a V oc of 1.13 V.

Garnet-type Li 7 La 3 Zr 2 O 12 (LLZO) ceramics has been considered as an ideal solid-state electrolyte for Li metal cells because of its high ionic conductivity and relatively stable interface with Li. However, it is electrochemically incompatible with some high-voltage cathodes, e.g. LiCoO 2 . In this work, a nanoscale Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) fast ion conductor was coated on LiCoO 2 (only 1 wt% LATP), bringing obviously enhanced interfacial compatibility with a composite electrolyte composed of Al, Nb-codoped LLZO and polyethylene oxide (PEO). A free-standing, flexible and ultrathin (20 μm) electrolyte membrane was successfully fabricated by a facile and scalable route, even though with a high ceramics content (67 wt%). Quasi-solid-state coin and pouch-type Li cells were assembled with the LATP-coated LiCoO 2 cathode, free-standing composite electrolyte and Li anode, together with soft interface modification by in-situ polymerization. The cells show stable cycling due to combined factors of enhanced electrode/electrolyte compatibility, ultrathin nature of the electrolyte membrane and the in-situ built soft interface. The pouch cells can be cycled for 300 cycles at 0.3 C and 60 °C with 80% retention. The pouch cells can endure abuse tests of bending, cutting and nail penetration. At a practical LiCoO 2 loading of 3 mAh cm −2 , the Li|LiCoO 2 pouch cell still shows stable cycling with 90% retention after 100 cycles at 60 °C (0.2 C charge/0.5 C discharge). This work provides a practical method to fabricate high-performance solid-state Li cells.

We explore the feasibility of using thermosensitive hydrogels based on copolymers of acrylic acid (AAC) and N-[3-(dimethylamino)propyl] acrylamide (DMAPAA) [P(AAC-co-DMAPAA)] for adsorption and desorption of phosphate in aqueous solutions by a temperature swing. The hydrogels were protonated when they swelled in acidic solution at room temperature, exhibiting good adsorption capacity of phosphate. The phosphate ions were desorbed at high temperature due to the ionic repulsion of carboxyl groups caused by the dissociation of hydrogen bonding. The hydrogels were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The effects of solution pH and temperature on phosphate removal were investigated. Kinetic data revealed that the adsorption of phosphate fitted the pseudo-first-order model. Isotherm data showed that the Freundlich model was more suitable than the Langmuir model. Effective desorption of phosphate was observed by raising the solution temperature to 55°C, and repeated adsorption and desorption behaviors were achieved within three consecutive cycles by a temperature swing between 25°C and 55°C. These findings suggest the possible phosphate removal and recovery from aqueous solutions by changing the environmental temperature.

Two novel red phosphors KBaEu(XO4)3 (X = Mo, W) have been synthesized by high-temperature solid-state reactions and the crystal structures were determined for the first time. Single-crystal X-ray diffraction data reveal that their space groups are C2/c. The crystalline structure is constituted of K/BaO8 distorted square antiprisms and distorted EuO8 polyhedra which form chains lying along the c-axis and two kinds of distorted XO4 tetrahedra. This high disorder of K/Ba which might lower the crystal field symmetry around Eu3+ results in the high purity of red emission around 615 nm originating from 5D0 → 7F2 transition under near-ultraviolet (NUV) excitation. With increasing temperature, the luminescence of KBaEu(XO4)3 (X = Mo, W) phosphors decreases almost linearly with subtle alteration for the CIE coordinate. As the temperature reaches 550 K, the red emission intensity decreases to 37.3% and 50.7% of that at 300 K for KBaEu(MoO4)3 and KBaEu(WO4)3, respectively. The analysis of the decay curves of the 5D0 → 7F2 emission at variable temperatures indicates the weak cross relaxation and non-radiative energy transfer between Eu3+ ions. These results demonstrate that the investigated phosphors are attractive for application in high power NUV excited white LEDs.

Recently, the use of polymers as thermoelectric materials has attracted considerable attention. However, relatively few studies have investigated the effects of polymer structures on the corresponding thermoelectric properties of the polymers. In this work, a series of poly(3-methylthiophene methine)s (PMMs) were synthesized for use as thermoelectric materials , and the effects on the Seebeck coefficient of donor or acceptor side groups at the methine carbon were studied. The PMMs with strongly electron-withdrawing and electron-donating groups exhibited the highest Seebeck coefficients. Motivated by the high Seebeck coefficients of the selected PMMs, PMM/graphite composites were prepared via solution mixing followed by mechanical ball milling and cold pressing. The thermoelectric properties of the composites were investigated as a function of the graphite (G) concentration. The highest ZT (6.23 × 10 −3 ) was measured for the poly[(3-methylthiophene-2,5-diyl) ( p -(methoxy)benzylidene)]/G composite that contained 90 wt% G. The results of this work suggest that the thermoelectric properties of polymer-inorganic composites can be improved by designing polymers with high Seebeck coefficients.

The mutual diffusion coefficients of binary mixtures, 3–methyl–1–butanol + n–heptane and 2–methyl–1–butanol + n–heptane, were measured over the mass fraction from 0.05 to 0.95 at temperatures T = 288.15 K, 298.15 K, 308.15 K and 318.15 K under atmospheric pressure. A digital holographic interferometry system was employed for the measurements and its expanded relative uncertainty of mutual diffusion coefficients was estimated to be less than 2.4%. The influences of temperature and composition on the mutual diffusion coefficients were investigated. Furthermore, the correlations of the mutual diffusion coefficients were fitted to the experimental data as functions of the mass fraction and temperature. The correlations represent the data with the absolute average of relative deviations (AARDs) of 0.88% for 3–methyl–1–butanol + n–heptane and 0.89% for 2–methyl–1–butanol + n–heptane, respectively.

A conducting polymer based composite material of poly(3,4-ethylenedioxythiophene) (PEDOT) doped with pure insoluble ionic liquid (IL), 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, was prepared through a cost-effective electrodeposition method. A very tiny amount of insoluble IL (less than 15 μL), containing 0.1 M conducting polymer monomer, was drop-coated on an electrode surface and then used for electropolymerization using a homemade electrochemical cell filled with aqueous supporting electrolyte. With this design, the consumption of expensive IL for the preparation of the PEDOT/IL composite was greatly reduced, and thus effectively reduced the cost. The prepared PEDOT/IL composite was found to be highly conductive and stable, and it exhibited a highly nanoporous microstructure and excellent electrocatalytic activity toward the oxidation of dopamine (DA). Based on the excellent stability and electrocatalytic activity of the PEDOT/IL nanocomposite, a highly stable, sensitive and selective DA sensor with a detection limit of about 51 nM was developed.

3-TPT is used for the efficient concentration of azurite for the first time. • 3‑TPT achieves a pronounced separation efficiency between azurite and K‑feldspar. • 3-TPT chemically adsorbs onto azurite via the formation of N Cu S C rings. The strong surface hydrophilicity of azurite leads to its low recovery, and the poor flotation separation between azurite and gangue minerals further reduces the utilization efficiency of copper. This study presents a novel selective collector 1-(3-(trifluoromethyl)phenyl)thiourea (3-TPT) for the efficient recovery of azurite from K-feldspar. Results from flotation tests and contact angle measurements indicate that with 150 mg/L 3-TPT, the contact angle of azurite surface raised to 79.4°, the recovery reaches 94.16 %, while K-feldspar remains hydrophilic, with a recovery of only 11.29 %. The selective adsorption mechanism of 3-TPT on azurite surface was revealed by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and Scanning Electron Microscope-Energy Dispersive Spectroscopy (SEM-EDS) analyses. XPS and FTIR analyses indicate that after the interaction of 3-TPT with the azurite surface, the C N stretching in 3-TPT exhibits a notable shift, and changes in the chemical states of Cu and S are observed during adsorption, confirming that 3-TPT chemically adsorbs onto azurite via the formation of N Cu S C rings, whereas its adsorption on K-feldspar is negligible. SEM-EDS results further confirm the selective interaction of 3-TPT on azurite surface, as evidenced by changes in surface morphology and elemental analysis. Characteristic elements S, N, and F from 3-TPT were clearly detected on the azurite surface in EDS mapping. This research highlights the potential of 3-TPT in copper concentration, not only improving the recovery efficiency of copper resources but also contributing to the advancement of more environmentally friendly direct flotation practices for copper oxide minerals.

Detection of 3-MCPD in lipid-rich food matrices remains challenging due to trace analyte levels, high viscosity, and severe matrix interference. Herein, a photothermal-driven magnetic “three-in-one” sensing platform based on L -cysteine-functionalized ZnFe 2 O 4 ( L -ZFO) nanoparticles was developed for rapid and sensitive screening of 3-MCPD in edible oils. The multifunctional platform integrates magnetic enrichment, photothermal-assisted signal amplification, and colorimetric sensing, enabling efficient extraction and detection with minimal sample pretreatment. Benefiting from the synergistic interfacial enrichment and photothermal enhancement, the proposed method exhibited a linear range of 0.01–0.20 mg/L with a low detection limit of 1.4 μg/L. The platform showed acceptable recoveries of 75.0–92.0% and relative standard deviations below 5.8% in edible oil samples. Moreover, comparable responses obtained in buffer and oil matrices demonstrated excellent anti-interference capability toward complex lipid systems. The recyclable L -ZFO probe also exhibited good stability and reproducibility over 3 cycles. This work provides an elimination of pretreatment strategy for rapid on-site screening of 3-MCPD in edible oils.

Background Enteric methane (CH 4 ) from ruminants represents a major contributor to agricultural greenhouse gas emissions. The red seaweed Asparagopsis taxiformis ( A. taxiformis ) is a highly effective CH 4 emission inhibitor, but its large-scale application is restricted by limited biomass availability. This study evaluated whether reducing the inclusion level of A. taxiformis (0.32% dry matter, DM) combined with 3-nitrooxypropanol (3-NOP; 0.05% DM) could maintain a high inhibitory efficacy, and elucidated the underlying microbial mechanisms through in vitro fermentation and metagenomics analysis. Results The combined treatment decreased CH 4 production by 98.21% ( P < 0.01) without impairing DM degradation, and markedly shifted rumen fermentation towards propionate, lowering the acetate-to-propionate ratio (1.59 vs. 2.65; P < 0.01). Metagenomic profiling revealed substantial reductions in the abundance of Methanobrevibacter and Ruminococcus , along with increased levels of propionate-associated bacteria such as Prevotella , Treponema , Eubacterium , and Selenomonas ( P < 0.01). Functionally, the combined treatment downregulated key enzymes in hydrogenotrophic and methylotrophic methanogenesis, including methyl-coenzyme M reductase (EC:2.8.4.1) and tetrahydromethanopterin S-methyltransferase (EC:2.1.1.86), thereby blocking terminal methanogenic steps. Conclusions Collectively, these results demonstrate that co-supplementation with A. taxiformis and 3-NOP achieves near-complete methanogenesis inhibition at drastically reduced seaweed dosage through coordinated changes in fermentation patterns, microbial community structure, and methanogenic enzymatic pathways. This approach provides a practical strategy to overcome biomass limitations of A. taxiformis and warrants validation in long-term in vivo trials.

Aberrant lipid metabolism is a hallmark of hepatocellular carcinoma (HCC), yet the regulatory mechanisms governing lipid droplet (LD) dynamics and their contribution to tumor progression remain poorly understood. Here, we developed an ultrasensitive phosphoproteomic platform using high-affinity HPDA@Ti4+ nanospheres to map LD-associated phosphorylation events across six HCC cell lines. By correlating phosphoproteomic signatures with LD morphology, we identified distinct regulatory signatures associated with LD size and abundance. Functional perturbation screens identified two distinct phosphoprotein modules controlling LD size: silencing SH3KBP1, SLK, EHD2, EPB41L3, and NEXN reduced LD size in Huh1 cells, whereas silencing CPD, BET1, UFL1, RRP1B, OGFR, and CD2BP2 enlarged LDs in Huh7 cells. Notably, we identified EPB41L3 as a critical metabolic-metastatic link; its loss decreased LD size and accelerated HCC migration and invasion, correlating with poor clinical prognosis. Crucially, we identified five key phosphorylation sites on EPB41L3 essential for its function; substituting these with alanine completely abolished its regulatory control over both LD size and HCC metastatic potential. Together, these findings delineate a phosphorylation-based regulatory network controlling the LD architecture and metastatic potential in HCC. Our study not only identifies potential therapeutic targets but also establishes a generalizable phosphoproteomic framework for interrogating lipid signaling in cancer metabolism.

Fluazinam is a benzamide fungicide commonly used in agricultural
production to prevent and control fungal-induced plant diseases. However,
its residues in food products can pose potential health hazards. To
address this issue, we have developed an electrochemical sensor based
on a MOF-5/AB-modified glassy carbon electrode (GCE) for sensitive
detection of fluazinam. In this work, a high-performance electrochemical
sensor was fabricated via a simple composite strategy by combining
AB, which possesses high electrical conductivity and superior electron
transfer ability, with MOF-5, a material featuring a well-developed
porous structure and large specific surface area. The structural and
morphological characteristics of the MOF-5/AB and electrochemical
sensing performance toward fluazinam of MOF-5/AB/GCE are investigated.
The MOF-5/AB/GCE exhibited outstanding electrochemical sensing performance
for fluazinam detection, providing an ultralow detection limit of
0.0166 μM, a wide linear range of 0–100 μM, high
sensitivity, excellent reproducibility and stability, and remarkable
selectivity against common interfering species. In real samples, fluazinam
yielded high recovery rates, confirming the potential of MOF-5/AB/GCE
for practical environmental and biomedical monitoring applications.
This research provides a novel and efficient sensing platform for
electrochemical detection of fluazinam residues and offers a valuable
reference for modification of MOFs and their extended applications
in the field of electrochemical sensing.
