Developing efficient catalysts toward the oxygen evolution reaction(OER) is important for water splitting and rechargeable metal-air batteries. Although NiFe oxides are considered as potentially applicable catalysts in the alkaline media, there are still a limited numbers of researches working on membrane electrode assembly(MEA) fed with pure water due to their poor electrical conductivity. In this work, antimony doped tin oxide(ATO) has been employed as conductive supports where NiFe layered double hydroxide uniformly dispersed[named NiFe-LDH(layered double hydroxide)/ATO]. The catalysts have been synthesized by a one-step co-precipitation method, and then NiFe-LDH/ATO-air plasma was obtained through mild air plasma treatment. According to XPS analysis, binding energies of Ni 2 p and Fe 2 p were shifted negatively. Moreover, a new signal of low oxygen coordination appeared on O 1 s spectrum after air plasma treatment. These XPS results indicated that oxygen vacancies(O v ) were generated after air plasma treatment. Electrochemical measurement indicated that the vacancy-rich NiFe-LDH/ATO-air plasma exhibited better performance than NiFe-LDH/ATO not only in 1 mol/L KOH solutions but also in an alkaline polymer electrolyte water electrolyzer(APEWE) fed with deionized water. This work provides a feasible way to design practical catalysts used in electrochemical energy conversion systems by choosing corrosion resistance supports and defect engineering.

Nanofluids incorporating metal nanoparticles hold considerable promise for optimizing spectral beam splitting in photovoltaic/thermal (PV/T) systems, but conventional metal based nanofluids suffer from poor stability and high cost. This study introduces highly stable ATO-ZnO hybrid nanofluids as a novel SBS for PV/T systems, resolving critical limitations of conventional metal-based nanofluids. Leveraging complementary optical properties—ZnO's exceptional ultraviolet (UV) absorption via direct bandgap transitions and ATO's strong IR harvesting through plasmonic resonance—the hybrid nanofluid exhibits enhanced optical transmittance (650–1050 nm) within the photovoltaic response band, while demonstrating strong absorption across other spectral regions.. The nanofluids demonstrate outstanding long-term stability. In PV/T testing, the hybrid system sets a new benchmark with 13.59% electrical efficiency and 57.69% thermal efficiency, achieving a merit function of 1.692 - substantially higher than values reported for metallic nanofluid SBSs in prior studies. Performance superiority originates from quantum-enhanced UV absorption and synergistic heat localization. Synthesized via scalable aqueous processing at low material cost, this technology establishes a new paradigm for solar energy utilization through simultaneous optimization of optical efficiency, thermal stability, and economic viability.

ATO hollow microspheres were synthesized with carbon ball template by the hydrothermal method . In order to study the likely formation mechanism of ATO hollow microspheres, the morphology, crystalline structure and microstructure were examined with XRD, SEM, EDS and HRTEM. The optical and thermal characteristics of the microspheres including absorption and reflectance, and thermal conductivity , infrared emissivity (8˜14 μm), and specific heat capacity were also measured. Silicone acrylic emulsion coating containing different dosages of ATO microspheres were then prepared, and their Vis-NIR transmittance and photo-thermal shielding performance were studied. Compared to solid microspheres, ATO hollow microspheres showed higher absorption, lower reflectance, lower thermal conductivity , higher specific heat capacity and higher infrared emissivity. Results also showed that ATO hollow microspheres introduction reduced the Vis-NIR transmittance of the silicone acrylic emulsion coating, and also enhanced the photo-thermal shielding performance of coating by higher absorption, slower thermal conduction and radiative cooling. This study indicates that coating containing ATO hollow microspheres is a promising material that can be applied for energy conservation.

The rate of complete remission of acute promyelocytic leukemia (APL) is currently over 90% because of the use of all-trans retinoic acid (ATRA) with arsenic trioxide (ATO). However, hemorrhagic mortality has emerged as the most significant barrier to APL-induced remission. Neutrophils extracellular traps (NETs/ETs) cause vascular leakage by damaging the integrity of endothelial cells. We have previously demonstrated that APL cells treated with ATRA/ATO undergo a cell death process, releasing extracellular chromatin, termed ETosis/NETosis. However, the mechanism underlying the involvement of ETs in endothelial injury in APL remain largely unknown. Here, we analysed the ability of mature and immature neutrophils to release ETs, and their interaction with platelets (PLTs) in APL. Importantly, the effect of ETs on vascular endothelium in APL was discussed. Our results showed that the ability of immature neutrophils to release ETs was impaired in APL, whereas mature neutrophils produced ETs, which were associated with activated PLTs. Moreover, ATRA+ATO induced immature neutrophil differentiation, as well as increased the release of ETs from mature neutrophils. The excessive ETs damaged endothelial cells, causing blood cell leakage. Removing ETs using DNase 1 alleviated endothelial damage and improved blood cells leakage. Our results indicate that vascular endothelial injury is at least partially associated with ETs in APL, and that targeting ETs production may be an effective approach for relieving vascular leakage and reducing the burden of bleeding in APL.

Antimony tin oxide (ATO) holds great promise as a transparent conductive oxide in near-infrared insulation applications. Reducing the particle size of ATO and improving its uniform dispersion are the key problems to be solved in preparing thermal insulation windows with excellent spectral selectivity. The post-synthetic dispersion of ATO is particularly challenging. This study introduced branched polyethyleneimine (PEI) as a novel dispersant for ATO. Through ball milling in ethanol, PEI's chelation and spatial stabilization efficiently reduced the average particle size of ATO to 26.7 nm. The resulting ATO ethanol dispersion demonstrated superior long-term storage and centrifugation stability. Compounding the dispersion with polyvinyl butyral (PVB) yielded ATO/PVB coatings, which exhibited the superior near-infrared shielding efficiency while maintaining a high visible transmittance and a low haze. Subsequently, the ATO/PVB coating exhibited excellent thermal insulation properties, reducing the temperature rise by 17.2°C compared to blank glass after 10 minutes of irradiation with a NIR lamp. The work demonstrates the potential of the coating for efficient energy-saving window applications.

One-dimensional titanium dioxide (TiO 2 ) whiskers with controllable aspect ratios were synthesized by molten salt method adopting anatase TiO 2 nanoparticles as precursor, sodium chloride (NaCl) and dibasic sodium phosphate (Na 2 HPO 4 ) as medium. The particle size of TiO 2 nanoparticles and ratio of precursor and medium that can help to generate high aspect ratio TiO 2 whiskers were studied and selected. Light-colored antimony-doped tin oxide @ titanium dioxide (ATO@TiO 2 ) conductive whiskers were prepared by coating ATO on TiO 2 whiskers through coprecipitation then. Finally, the ATO@TiO 2 light-colored conductive whiskers were dispersed in polyacrylonitrile (PAN) to fabricate light-colored conductive fibers. The experimental results show that the ATO@TiO 2 whiskers exhibits ideal whiteness and conductivity with 65.5 Wb and 106 Ω·cm, respectively, and the resistivity of conductive fibers was 6.07×10 6 Ω·cm with 15wt% whisker content.

Solar heat blocking materials, which can not only strongly shield the near infrared (NIR) heat rays, but also retain high visible transparency, have been widely studied and used in energy conservation of buildings . In this work, a complete process for preparation of waveband two-component transparent NIR shielding (WTNS) coatings combined ATO (antimony doped tin oxide) and Cs 0.33 WO 3 nanomaterials is proposed. ATO and Cs 0.33 WO 3 were synthesized by controllable hydrothermal methods and dispersed by a ball mill with silane coupling agents . The transmittance spectra demonstrate that WTNS coated glass shows excellent NIR shielding performance in a wide-band wavelength from 780 nm to 2500 nm, which could shield the NIR light as much as 90.9% and retain high transparency in the visible light of 70.6%. The overall energy performance assessment of this NIR shielding coatings was obtained, which includes thermal chamber test and software simulation in EnergyPlus . The chamber tests reveal the superior thermal insulation ability of WTNS coatings. The simulations indicate that for the area like Hong Kong which is cooling dominated areas, WTNS coated glass has the best energy performance which can significantly save up to 15.22% and 9.15% electricity per year in comparison with the normal glass and low-e glass, respectively.

This study focuses on the development of high-performance and durable supported iridium-based catalysts. Mesoporous antimony tin oxide (ATO) supports with high conductivity, high specific surface area, and rich in oxygen vacancies is prepared by employing a Pt-catalyzed oxidation of carbon template removal approach. The pore sizes of mesoporous ATO supports are tuned from 5 to 12 nm by adjusting the template removal temperature. These supports, used for IrO 2 substrates, improved ultrahigh OER performance, both catalytic activity and mass transfer, demonstrated excellent Proton exchange membrane water electrolysis (PEMWE) performance with a 0.3 mg cm −2 of Ir loading, with a polarization performance of 1.75V@2A cm −2 . Simultaneously, the ATO-supported catalysts demonstrated outstanding performance even at ultra-low loadings owning to the ATO mesoporous structure and surface oxygen-vacancy, achieving 1.8V@2A cm −2 with an Ir loading of 0.05 mg cm −2 . Density functional theory (DFT) computations revealed the strong oxide-support interaction (SOSI) between the IrO 2 and ATO. This research not only validates the effective role of conductive ATO in supported iridium-based catalysts but also provides valuable guidance on the influence of support pore structure to the supported iridium-based catalysts. It offers a new perspective for the development of supported low-iridium OER catalysts.

Solar thermal membrane distillation is a promising technology for low-cost desalination and water purification . A novel photo-thermal conversion membrane composited by polyacrylonitrile (PAN) nanofiber layer and polyvinylidene fluoride (PVDF) with antimony tin oxide (ATO) as solar-thermal nanoparticles (PVDF-ATO/PAN nanofiber membrane) was fabricated by sequent electrospinning techniques. The dual-layer membrane with hydrophilic PAN and hydrophobic PVDF-ATO was examined by microscopic evaluation and contact angle measurement. In situ temperature increase on membrane superficial layer (PVDF-ATO) driven by solar light illumination was confirmed by thermal imaging system. PAN layer provides water transport channels for facilitating water flow of highly efficient membrane distillation and avoids the salting assembly during the vigorous evaporation. With the help of hydrophilic PAN layer, our PVDF-ATO/PAN nanofiber membrane can fulfill highly effective localized heating transfer with an evaporate rate of 0.93 kg m −2 h −1 , showing great potential for low-cost water desalination and scalable water purification.

Wearable strain sensors have made great progress in sensing performance, stretchability and durability. However, practical applications of these sensors are still quite challenging because they are incapable of detecting multi-degree-of-freedom strains due to the interference of multidirectional strains. Herein, a high-sensing-performance, direction-aware and transparent strain sensor is reported based on antimony-doped tin oxide oriented nanofiber (ATO-ONF) films prepared by electrospinning. The monolayer ATO-ONF strain sensor shows remarkable anisotropic sensing performance, namely GFs of 250 and 1.2 for the nanofiber orientation and its transverse directions, suggesting the realization of the unidirectional sensing capability of the strain sensor, i.e. , only responding to strains along the nanofiber direction. In addition, this strain sensor also exhibits high transparency with a light transmittance of ∼ 80%, and excellent sensing performance including high sensitivity, high linearity, low hysteresis, good repeatability and durability (>2000 cycles). Based on these superior sensing properties, the direction-aware biaxial strain sensor is designed by orthogonally stacking ATO-ONF films, by which the predicted magnitude and direction of the tensile strains agree well with those of the actual strains. Furthermore, the multi-degree-of-freedom applications of direction-aware strain sensors in human motion monitoring and human–machine interaction are demonstrated, showing a great application potential in next-generation wearable electronics.

Surface-enhanced Raman scattering (SERS) has been applied in many fields, but still has the limitation of widespread applications on semiconductor substrates. In this work, a series of antimony-doped tin oxide (ATO) nanoparticles (NPs) have been synthesized by a hydrothermal method and were used as SERS substrates for the first time. Interestingly, a charge transfer (CT) effect was revealed between the probing molecules of 4-mercaptobenzoic acid (4-MBA) and the substrates of ATO NPs, which accounts for the SERS enhancement and shows dependence to the Sb ions doping ratios in ATO NPs. By considering the energy level diagram of the ATO–MBA complexes and the doping theory of semiconductors, this phenomenon is believed to connect to the variance of the optical band gap energy ( E g ), which is accompanied with the changes of free charge carrier densities in conduction bands (CBs) of ATO NPs due to different doping contents. The study of the E g - or free-charge-carrier-density-dependent property of the semiconductor-based SERS provides a new point of view for the development of new semiconductor SERS substrates and also contributes to the SERS CT mechanism.

Tumoral thermal defense mechanisms considerably attenuate the therapeutic outcomes of mild-temperature photothermal therapy (PTT). Thus, developing a simple, efficient, and universal therapeutic strategy to sensitize mild-temperature PTT is desirable. Herein, we report self-delivery nanomedicines ACy NPs comprising a near-infrared (NIR) photothermal agent (Cypate), mitochondrial oxidative phosphorylation inhibitor (ATO), and distearoylphosphatidylethanolamine-polyethylene glycol 2000 (DSPE–PEG2000), which have a high drug-loading efficiency that can reverse tumoral thermal resistance, thereby increasing mild-temperature PTT efficacy. ACy NPs achieved targeted tumor accumulation and performed NIR fluorescence imaging capability in vivo to guide tumor PTT for optimized therapeutic outcomes. The released ATO reduced intracellular ATP levels to downregulate multiple heat shock proteins (including HSP70 and HSP90) before PTT, which reversed the thermal resistance of tumor cells, contributing to the excellent results of mild-temperature PTT in vitro and in vivo. Therefore, this study provides a simple, biosafe, advanced, and universal heat shock protein-blocking strategy for tumor PTT.
