Electromagnetic pollution and radiation now extend to encompass millimeter waves, while the development of broadband millimeter-wave absorbers remains significantly hindered by lacking efficient loss mechanisms. High-entropy M-type ferrites are promising due to their excellent magnetic resonance and dielectric polarization, yet precise electromagnetic parameter regulation remains challenging because intermediate-phase impurities persist from insufficient configurational entropy. Herein, we propose an iron-deficient strategy to synthesize the single-phase Zr 4+ -doped high-entropy M-type ferrites. It is found that iron deficiency eliminates impurities by enhancing entropy and provides a more adaptable local structure. The synergistic effect of high entropy and iron deficiency amplifies the dielectric loss capacity, while Zr 4+ doping broadens the magnetic loss range by modulating natural resonance. This yields an ultra-broad absorption bandwidth of 12.18 GHz and ultra-thin matching thickness below 1 mm within the millimeter-wave atmospheric window around 35 GHz, offering insights for absorbers against electromagnetic pollution and radar stealth.

Facing the complex application environment and overall inefficiency in the complete water-splitting process, the development of highly efficient and stable catalytic materials is urgently required. This study innovatively proposes and for the first time implements a rapid synthesis technique driven by microwave-induced sulfur sublimation, successfully preparing MS 2 /RuS 2 (M = Co, Fe, Ni) heterostructure interfaces with high structural stability and uniform active site distribution within merely 60 s. By incorporating iron-group sulfides, the electronic structure of pyrite-type RuS 2 is effectively modulated, enabling the developed MS 2 /RuS 2 @G catalyst to exhibit superior activity in alkaline environments. Particularly, the cobalt-based sulfide regulated pyrite-type RuS 2 (CoS 2 /RuS 2 @G) achieves a mass activity in the hydrogen evolution reaction (HER) that is 15.4 times that of 20 wt.% Pt/C, and in the oxygen evolution reaction (OER), it surpasses commercial IrO 2 by two orders of magnitude. This research not only provides a new pathway for enhancing the performance and environmental adaptability of water-splitting catalysts but also presents a simple and universal method to boost catalytic activity through a synergistic modulation strategy.

Redox sites and acidic sites are the main active sites of bimetallic oxide catalysts used for selective catalytic oxidation of NH 3 (NH 3 -SCO). In this work, three MMoO x (M = Cr, Fe, and Mn) bimetallic oxides catalysts were prepared by simple grinding and calcination to investigate the effect of redox sites (M sites) on the NH 3 -SCO performance. The NH 3 -SCO test results showed that the activity of MMoO x is in the order of CrMoO x > MnMoO x > FeMoO x . The characterization results of H 2 -TPR, O 2 -TPD, NH 3 -TPD, and in situ DRIFTS proposed that the NH 3 -SCO reaction on MMoO x catalysts is proceed via i-SCR mechanism, and the formation of the intermediates of NH 3 -SCR reaction is the decisive reaction step. Owing to the excellent ability in promoting the formation of nitrate/nitrite species, CrMoO x and MnMoO x samples show much higher NH 3 -SCO activity than FeMoO x sample . CrMoO x can facilitate the formation of a large amount of –NH 2 species, which together with nitrate/nitrite species enhance the NH 3 -SCO reaction via i-SCR reaction route. Therefore, CrMoO x shows the highest NH 3 -SCO activity among the MMoO x catalysts. Through this work, the redox sites of bimetallic oxide catalysts are demonstrated as a vital role in inducing the formation of reaction-active intermediates, which highlight the importance of choosing the redox sites in designing NH 3 -SCO catalyst.

Universal antibody purification remains challenging because conventional ligands (Protein A/G/L) target specific antibody regions, limiting their general application. In contrast, protein M from human mycoplasma exhibits unprecedented broad-spectrum binding to diverse antibody types through interaction with the conserved part of the variable domain of the light chain. Its engineered variant, protein M-8His, introduces pH-responsive histidine residues while maintaining this broad binding capability, but the molecular mechanisms governing its variable performance across different antibodies remain poorly characterized. To investigate this, we developed an antibody purification platform through site-specific immobilization of protein M-8His on Ni 2+ -modified superparamagnetic nanoparticles (NiNPs). NiNPs demonstrated a protein M-8His recoverable binding capacity of 74.41 mg/g. The resulting protein M-8His functionalized NiNPs (MNiNPs) demonstrated broad-spectrum antibody binding, with recoverable binding capacities up to 52.01 mg/g for trastuzumab scFv, while maintaining 76.1 % activity after 15 days of storage. Molecular dynamics simulations suggested two distinct interaction patterns: histidine-dominated interactions driving pH-dependent elution (H337/H338 for trastuzumab scFv) and mixed-interaction binding with reduced histidine contribution (for S2P6 and 76E1 antibodies), explaining the observed performance variations. Energy decomposition analysis showed that trastuzumab scFv (100 %) and 76E1 Fab (85.1 %) predominantly bind via Fv domain while S2P6 Fab mainly binds via constant domain (76.7 %). These findings provide mechanistic insights into protein M-8His interactions and lay a foundation for optimizing protein M-8his for industrial applications.

The addition sensing device of sweat to wearable biostress sensors would eliminate the need for using multiple gadgets for healthcare analysis. Due to the distinct package fashion of sensor interface for biostress and biomolecule, achieving permeability and multifunctionality in an integrated wearable sensor remains a formidable challenge. Here, a viscose fabrics (VCFs)@silver (Ag) sensing material and encapsulating strategy by multi-microporous membranes (M-MPM) are developed, and simultaneous detection for muscle strain and molecule biomarkers in sweat (glucose, lactate, uric acid) is realized. The package interface exhibits good breathability, directional, and fast sweat transport without interception due to its wetting gradient enabled by the 3D-stacking for VCFs@Ag and M-MPM, which subjoins sensing function of sweat on the biostress sensing platform. And, the filtration effect of M-MPM can resist the pollutant interference to the hand-held surface-enhanced Raman scattering spectrum on skin surface. Then, a bidirectional memory network is constructed to correct for the changes in electrical conductivity of VCFs@Ag under the influence of sweat infiltration. With the help of a machine learning pipeline, the accuracy of multimodal recognition increased to 88.6%. As proof of concept, the package interface of M-MPM/VCFs@Ag provides the feasibility of simultaneous monitoring of the muscle strain and sweat with a single sensor.

In this work, a series of Ni 1-x M x (M = Cr, Mo, W) nanoparticles (NPs) have been successfully synthesized via a simple surfactant-aided co-reduction method and employed as highly efficient and cost effective catalysts for hydrogen generation from aqueous solution of ammonia borane (NH 3 BH 3 , AB) at room temperature . It is found that the as-synthesized NiM NPs (M = Cr, Mo, W) exhibit much higher catalytic performance for the hydrolysis of AB as compared to that of pure Ni NPs. In addition, among all the Ni 1-x M x (M = Cr, Mo, W) NPs, the Ni 0.9 Cr 0.1 , Ni 0.9 Mo 0.1 , and Ni 0.8 W 0.2 NPs show the highest catalytic activities with the turnover frequency (TOF) values of 10.7, 27.3 and 25.0 mol H 2 (mol metal min) −1 , respectively. Remarkably, these optimized NiM catalysts can also perform efficiently in the hydrolysis of hydrazine borane (N 2 H 4 BH 3 , HB). The present low-cost and high-performance of the NiM catalysts system may encourage the practical application of AB and HB as the promising chemical hydrogen storage materials .

A novel β-cyclodextrin (β-CD)/polyamide film reverse osmosis (RO) membrane was prepared by in situ interfacial polymerization via mixing β-CD with m-phenylenediamine in the aqueous phase prior to reaction with trimesoyl chloride. The effects of the β-CD concentration on the morphology and separation performance of the RO membrane were studied. β-CD was employed to improve the pure water flux of the membrane. When the concentration of β-CD in aqueous solution was 1.5% (w/v), both the rejection of NaCl and the pure water flux were maintained at a high level. In this case, water flux of the β-CD-modified RO membrane was nearly1.52 times that of the β-CD-free polyamide membrane. This increase might have been caused by the high concentration of β-CD hydrophilic hydroxyl groups, which appeared to directly improve the performance of the composite film. In addition, the unique properties of the resulting membrane, including the loosely cross-linked structure formed by β-CD and the polyamide film, the intramolecular cavity existed in β-CD and the affinity of β-CD to water molecules, was ascribed as the reasons for the improved performance of higher permeability.

A fast, low-temperature hydrothermal method was introduced to prepare a VxW1−xO2(B) ultrathin nanostructure which can be easily transformed into VxW1−xO2(M) via a fast annealing process in an inert atmosphere. Thermochromic foils coated with ultrathin V0.98W0.02O2(M) nanopowders exhibited unsatisfactory optical properties with a weak solar regulation efficiency (ΔTsol, 4.6%) and a low luminous transmittance (Tlum-L, 15.73%) in a low-temperature state. Coating the VxW1−xO2(M) nanostructure with a thin shell of SiO2 can improve the optical performance of the thermochromic foils resulting in ΔTsol of 7.15% and Tlum-L of 25.74%. Furthermore, etching the V0.98W0.02O2(M)@SiO2 core–shell nanostructure with diluted hydrochloric acid (HCl) can optimize the optical properties of the thermochromic foils well, resulting in ΔTsol and Tlum-L of up to 10.18% and 37.37% owing to the decreased size. In summary, we employed a simple method to synthesize V1−xWxO2@SiO2 ultrathin nanostructures and provided new insight into optimizing VO2-based thermochromic windows.

Tetragonal La2BaIn2O7 belongs to the stoichiometric n = 2 members of the Ruddlesden–Popper (RP) structure, with La3+ and Ba2+ cations ordered in the rock salt and octahedral layers, respectively. Herein, a series of alkaline-earth-metal-doped materials La2–xMxBaIn2O7–0.5x (M = Ca, Sr, Ba) were prepared by the traditional solid-state reaction method. The results revealed that the substitutions of Ca/Sr/Ba for La introduced oxygen vacancies and led to good oxide ion conduction, e.g., ∼1.21 × 10–3–1.38 × 10–2 S/cm within 600–900 °C for the specimen La1.7Ba1.3In2O6.85, which was more than 2 orders of magnitude higher than the parent material. However, both the parent and acceptor-doped La2BaIn2O7 showed very limited proton conductions. The energetics of defect formation and oxygen vacancy migrations in La2BaIn2O7-based materials was studied through the static lattice and molecular dynamics (MD) atomistic simulations based on the interatomic potential approach. The defect formation energy calculations for the electrons and holes in La2BaIn2O7 rationalized the experimentally observed pure ionic conduction under low pO2 and mixed ionic and p-type electronic conductions under high pO2, respectively. The MD simulations indicated two-dimensional oxygen vacancy migration within the perovskite slab for the acceptor-doped La2BaIn2O7.

Near-infrared (NIR) phosphor-converted LED (pc-LED) has emerged as a smart light source for multifunctional applications, driving demand for developing high-performance NIR phosphors. However, the design rules for such materials have not been systematically established due to large differences in material systems, compositions, and crystal structures of currently developed materials. Herein, two isostructural and compositionally similar garnet-type phosphors Ca2YZnMGe3O12:Cr3+ (M = Sc, In) were designed and synthesized, which show markedly different performance characteristics, namely, upon 460 nm excitation, the Sc-based garnet achieved an ultrahigh photoluminescence quantum yield (PLQY = 94.0%) and a superior thermal stability (I423 K/I298 K = 81.1%), while the In-base garnet showed a moderate performance (PLQY = 84.8%, I423 K/I298 K = 65.6%), providing an opportunity to reveal the discrepancy in structure and photoluminescence properties via a comparative study. Moreover, an NIR pc-LED device was fabricated by integrating the highly efficient Sc-based garnet with an InGaN LED, which demonstrated excellent performance in information encryption and night vision applications. Therefore, this work not only offers a high-performance NIR phosphor for multifunctional applications but also gives some inspirations for materials design by comparatively analyzing the correlations between structure and properties.

The inhibitive ability of 2,6-diaminopyridine, tartaric acid and their synergistic effect towards mild steel corrosion in 0.5 M HCl solution was evaluated at various concentrations using potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and weight loss experiments. Corresponding surfaces of mild steel were examined by atomic force microscope (AFM), field emission scanning electron microscope (FE-SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS) analysis. The experimental results are in good agreement and reveal a favorable synergistic effect of 2,6-diaminopyridine with tartaric acid, which could protect mild steel from corrosion effectively. Besides, quantum chemical calculations and Monte Carlo simulation were used to clarify the inhibition mechanism of the synergistic effect.

The advancement of millimeter-wave communication desires the ceramic substrate with low permittivity ( ԑ r ) to meet the requirements of high transmission rates, low latency and wide bandwidth. However, the thermal conductivity of most low- ԑ r ceramics is too low to deal with heat dissipation in millimeter-wave applications. In this paper, we reported novel dielectric ceramics Li M SiO 4 ( M = Ga, Sc and Y) with excellent performances of low ԑ r (< 10) and high thermal conductivity (> 6 W mK −1 ). Their dielectric properties in both microwave and THz were investigated, where the LiGaSiO 4 ceramic achieved the lowest ԑ r of ∼5.2, the LiScSiO 4 ceramic presented extremely low loss ( Q × f ∼ 96,700 GHz, Q = 1/dielectric loss, f is resonant frequency), and the LiYSiO 4 ceramic showed a positive temperature coefficient of f (TCF ∼ +32 ppm °C −1 ). The distinct dielectric behavior was subsequently studied by structure-performance relationship in terms of M -site cations and bond parameters using bond valence theory, Phillips–Van Vechten–Levine chemical bond theory and so on. Moreover, a 36 GHz microstrip array antenna was designed and simulated using the LiGaSiO 4 ceramic substrate, obtaining high realized gain, high radiation efficiency and low sidelobe. The result demonstrated the great potential of LiMSiO 4 -type dielectric ceramics in millimeter-wave communications.
