Hybrid solid-state electrolytes are emerging as a promising solution to achieving high ionic conductivity, excellent mechanical properties, and good safety for developing high-performance rechargeable batteries. In this work, we prepared a polymer (PAN)-based hybrid solid-state electrolyte. The composite membrane (PLL) is composed of polyacrylonitrile (PAN) matrix, bistrifluoromethanesulfonimide lithium salt (LiTFSI) and Li1.3Al0.3Ti1.7(PO4)3 (LATP) particles. The solid-state lithium battery with this composite membrane, Li metal anode and LiNi0.8Co0.1Mn0.1O2 cathode exhibits an initial reversible discharge capacity of 197 mAh g-1 at a charge/discharge current density of 0.5 C at room temperature. The battery using the PLL-20 electrolyte exhibits more stable cycling performance and higher reversible capability than those of the battery with PLL-10, 30 membrane electrolytes and commercial PE separator. © 2023, The Authors.

Improving elastocaloric effect (eCE) and mechanical properties is the key to developing high-performance eCE cooling materials. In this paper, the metamagnetic shape memory alloys Ni35.5Co13.5Mn35Ti15-x Gdx was successfully prepared by arc melting method, and the effects of Gd substitution for Ti on the martensitic transformation (MT) temperature, phase composition, microstructure, eCE and mechanical properties of the alloys were systematically investigated. With the introduction of Gd elements, transformation temperature shifts to low temperature, and the mechanical properties of the alloy are also enhanced. The maximum compressive strength increased from 980MPa (x=0) to 1142MPa (x=0.9). At room temperature, a large adiabatic temperature change of +13.5/-12.7 K is obtained after loading/unloading, and a constant temperature change of +5.6K/-5.5K is obtained without apparent degradation under the compressive stress of 400 MPa during 61 cycles for Ni36.5Co13.5Mn35Ti14.9Gd0.1 alloy. The underlying mechanism of the enhanced eCE and mechanical properties is also discussed. © 2023, The Authors. All rights reserved.

Herein, high-quality BiFe0.92Mn0.08O3/BiCrO3 composite films were obtained by a sol-gel process and a comprehensive investigation of the film growth, domain structure, multiferroic, and optical properties was provided. These novel BiFe0.92Mn0.08O3/BiCrO3 films exhibit excellent multiferroic characteristics, which can be used as an absorber layer in ferroelectric photovoltaic solar cells. Moreover, the BiCrO3-based interlayers can reduce leakage current density of BiFe0.92Mn0.08O3/BiCrO3 films, resulting in more efficient ferroelectric properties. The superexchange interaction between Fe and Cr is achieved at theBiFe0.92Mn0.08O3/BiCrO3 interface by the magnetic coupling between Fe3+ and Cr3+ ions through paramagnetic oxygen atoms, which enhances the ferromagnetic properties of the films. Amazingly, these polarized materials can be tuned to cover more portion of the solar spectrum as a noteworthy spectral red-shift towards the visible region was discovered. This phenomenon was correlated to an occurrence of ferromagnetism, revealing the significant impact of physical materials non central symmetry structure on their chemical behaviors. © 2024, The Authors.

The interstitial site engineering that purposely creates interstitial luminescent centers in suitable hosts has become an intriguing strategy in designing novel inorganic phosphors. However, effectively tuning the photoluminescence of interstitial activators remains tough challenging at this stage. Here, we demonstrate the effective modulation of interstitial luminescence in inorganic phosphor. In detail, the blue emission band (λem = 446 nm) of interstitial Eu2+ doped α-cristobalite (SiO2:Eu2+) is largely enhanced and broadened via a partial, aliovalent substitution of Si4+ by Al3+. After introducing Al3+ ions into SiO2 lattice, the full width at half maximum of the blue emission band increase from 59 to 76 nm with a triple growth in quantum efficiency (10.82% → 35.56%). Moreover, the thermal stability improves significantly with a high emission retention of 60% at 325 °C (SiO2:0.06Al3+,0.005Eu2+), far higher than that of the parent SiO2:0.005Eu2+ (30%). Encapsulating blue-emitting SiO2:Al3+,Eu2+ along with two commercial green and red phosphors on an ultraviolet LED chip (λem = 375 nm), a white LED device with high color rendering index (Ra > 90) was successful fabricated, showing the great potential of this phosphor for achieving high-quality white LED lighting. This study not only provides a promising bule emitter but also sheds light on modulating interstitial luminescence properties in inorganic phosphors. © 2025 Elsevier Ltd and Techna Group S.r.l.

To improve the removal capacity of NO + O_(2) effectively, the alkaline earth metal-doped order mesoporous carbon(A-C-FDU-15(0.001)(A = Mg, Ca, Sr and Ba)) and Mg-C-FDU-15( x)( x = 0.001-0.003) samples were prepared, and their physicochemical and NO + O_(2) adsorption properties were determined by means of various techniques. The results show that the sequence in(NO + O_(2)) adsorption performance was as follows: Mg-C-FDU-15(0.001)(93.2 mg/g) > Ca-C-FDU-15(0.001)(82.2 mg/g) > Sr-C-FDU-15(0.001)(76.1 mg/g) > Ba-C-FDU-15(0.001)(72.9 mg/g) > C-FDU-15(67.1 mg/g). Among all of the A-C-FDU-15(0.001) samples, Mg-C-FDU-15(0.001) possessed the highest(NO + O_(2)) adsorption capacity(106.2 mg/g). The species of alkaline earth metals and basic sites were important factors determining the adsorption of NO + O_(2) on the A-C-FDU-15( x) samples, and(NO + O_(2)) adsorption on the samples was mainly chemical adsorption. Combined with the results of(NO + O_(2))-temperatureprogrammed desorption((NO + O_(2))-TPD) and in situ diffused reflectance infrared Fourier transform spectroscopy(DRIFTS) characterization, we deduced that there were two main pathways of(NO + O_(2)) adsorption: one was first the conversion of NO and O_(2) to NO_(2) and then part of NO_(2) was converted to NO_(2)^(-) and NO_(3)^(-);and the other was the direct oxidation of NO to NO-2 and NO_(3)^(-).
