Intermediate temperature NaCl–AlCl3-based Al-ion batteries are considered as a promising stationary energy storage system due to their low cost, high safety, etc. However, such a cheap electrolyte has a critical feature, i.e., strong corrosion, which results in the short cycle life of the conventional Al-metal anode and also limits the development of the NaCl–AlCl3-based Al-ion batteries. A noncorrosive electrolyte may be a good choice for addressing the above challenge, while it is difficult to obtain the electrolyte that has advantages of both noncorrosion and low cost. Therefore, here, we report a Ga-metal anode in the affordable NaCl–AlCl3 electrolyte for constructing a long-life stationary Al-ion energy storage system. This featured liquid metal anode shows good alloying and dealloying processes between metallic Ga and Al, as well as renders superior stability of the interface between the electrolyte and the anode (e.g., smoothly running for over 580 h at 2 mA cm–2). No-corrosion and no-pulverization problems appear in this novel liquid/liquid interface. Those advantages demonstrate that the liquid Ga-metal anode has a great promise for the improvement of the NaCl–AlCl3-based Al-ion batteries for large-scale stationary energy storage applications.

The objective of the present work was to investigate the effects of the mixture of nonionic/ionic surfactants on nanostructured lipid carriers (NLCs). Nonionic surfactant (polyethylene–poly(propylene glycol), Pluronic F68) and ionic surfactant (octenylsuccinic acid modified gum arabic, GA-OSA) were chosen as emulsifier for NLCs. The NLCs systems, which were composed of lipid matrix, modified 4-dedimethylaminosancycline (CMT-8), and various emulsifier agents, were characterized with dynamic light scattering (DLS), high performance liquid chromatography (HPLC), transmission electron microscopy (TEM), small-angle X-ray scattering (SAXS), differential scanning calorimetry (DSC), in vitro release, and phagocytosis assay. This mixture of nonionic/ionic surfactants showed significant effects on physical properties including particle size, polydispersity index (PDI), entrapment efficiency, and particle morphology. Compared with single stabilizer, this mixed nonionic/ionic surfactant system provided NLCs with better drug carrier properties including prolonged release profile and low phagocytosis by phagocyte. We expect that these explorations can provide a new strategy for the development of lipid nanoparticles as drug delivery.

Abstract Hierarchically ZSM-5 zeolite was prepared by alkali treatment. It was used as a support for a series of Co-based catalysts for Fischer–Tropsch synthesis with Fe, Ti, Ga or Zn as promoter. This series of catalysts were named Co/M-ZSM-5 (M = Fe, Ti, Ga or Zn). The catalysts were characterized by SEM, XRD, H 2 -TPR, and XPS, and the FTS catalytic performance of catalysts were compared. The character date revealed that the promoter changed the dispersion, reducibility and stability of Co. The addition of Zn and Ga increased the activity of catalysts, decreased the selectivity to CH 4 . The Ti promoted catalyst had the highest initial activity, but it deactivated rapidly. The suitable interaction between Co and the Fe-ZSM-5 result in the suitable dispersion and reduction. Thus Fe is the better promoter for the catalyst Co/ZSM-5. Graphical Abstract

Exploration of new iodates is crucial due to their splendid applications in the nonlinear optical (NLO) field. Two new IIIA metal iodate–selenates, namely, [M(OH)2]3(IO3)(SeO4)·H2O (M = Ga and In), have been successfully synthesized using the hexagonal tungsten oxide (HTO) framework as an ideal structural template. Isostructural [M(OH)2]3(IO3)(SeO4)·H2O (M = Ga and In) crystallize in the polar space group P63mc. Their structures feature ∞[MO2(OH)2]3− (M = Ga, In) layers composed of corner-shared circular M3O6(OH)9 trimeric units based on MO2(OH)4 octahedra. The SeO4 groups are capped above half of the trimeric units of the layers while the IO3 groups are capped below the remaining trimeric units of the layers. Both compounds exhibit moderate phase-matchable second-harmonic generation (SHG) responses (2.9× and 3.8× KH2PO4) under 1064 nm laser radiation and the same band gap of 3.38 eV. Results of theoretical calculations revealed that their SHG effects originated from the synergistic effect of MO6, IO3 and SeO4 groups. So far reports on iodate–selenates are scarce and this work provides a new perspective to design new NLO materials through polar HTO-type topologies and a mixed-anionic strategy.

Ga and F co-doped ZnO (GFZO) thin films were prepared on quartz substrates via the sol-gel spin-coating method, followed by annealing in O 2 , Ar, N 2 , and H 2 atmosphere. The effects of annealing atmosphere on the structure, optical transmission, electrical properties, and thermal stability of GFZO films were systematically investigated. All GFZO films exhibited a typical wurtzite structure with a c-axis preferential orientation. The average optical transmittance of GFZO films annealed in Ar, N 2 , and O 2 atmospheres exceeded 90% in the visible region, while that of the H 2 -annealed sample was about 60%. The resistivity values of GFZO films annealed in Ar, N 2 , and H 2 atmospheres ranged from 1×10 -3 to 3×10 -3 Ω·cm at room temperature, whereas the film annealed in O 2 showed a much higher resistivity of 7.887×10 5 Ω·cm. Notably, the GFZO thin films annealed in Ar or N 2 atmosphere can maintain a low resistivity of 8×10 -3 Ω·cm even at 500 °C while retaining excellent thermal stability. With high optical transmittance, low electrical resistivity, and outstanding thermal stability, the Ar and N 2 annealed GFZO thin films are highly suitable for transparent conductive thin film applications.

Luminescence pressure sensors, valued for their remote sensing capability and high resolution, have been developed recently. However, most current sensors rely on a linear relationship between an optical property and pressure. We propose a nonlinear machine learning (ML) method to model the luminescence intensity ratio (LIR) as a function of pressure. The versatility and performance of this method are demonstrated using (Y,Gd)(Al,Ga) 3 (BO 3 ) 4 :Cr 3+ phosphors as luminescent pressure sensors. The relative sensitivities of the 2 E → 4 A 2 / 4 T 2 → 4 A 2 LIRs in (Y,Gd)(Al,Ga) 3 (BO 3 ) 4 :Cr 3+ range from 1.58%/GPa to 25.27%/GPa. The ML fitting demonstrates a superior performance compared to linear fitting, with lower mean absolute errors (0.0355–0.1499 GPa vs. 0.1209–0.6955 GPa) and higher R 2 values (99.70–99.98% vs. 93.69–99.79%). The ML fitting method is more suitable for modeling the nonlinear relationships between LIR and pressure than traditional linear fitting. The nonlinear ML fitting approach offers a powerful new way to model the relationships between luminescence features and various physical parameters.

Nasicon-type Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) is a potential electrolyte for lithium-ion batteries due to its appropriate conductivity and good air stability. Herein, LATP was co-doped with Ga and Si to improve its ionic conductivity. The Li 1.325 Al 0.29 Ga 0.01 Ti 1.7 Si 0.025 P 2.975 O 12 (LAGTSP025) electrolyte exhibits an ionic conductivity of 8.92 × 10 −4 S/cm at 30 °C, which is mainly ascribed to its enlarged crystal lattice and high densification. This electrolyte material was incorporated into poly(ethylene oxide) (PEO) polymer to form a polymer-based PEO-LITFSI-LAGTSP025 solid composite electrolyte (SCE). The optimized SCE shows a high ionic conductivity of 5.33 × 10 −4 S/cm and excellent interfacial stability at 60 °C. Consequently, a Li/SCE/Li symmetric battery can stably cycle for 1600 cycles at a current density of 0.1 mA/cm 2 . Moreover, an LFP/SCE/Li all-solid-state lithium-ion battery (ASSLIB) maintains a discharge capacity of 143.56 mAh/g and exhibits 95.21% capacity retention after 300 cycles at 0.5C. This work demonstrates PEO-LITFSI-7.5LAGTSP025 SCE is a potential solid electrolyte for ASSLIBs.

Indium tin oxide (ITO) is usually served as the transparent conductive electrode of Cu(In, Ga)(S, -Se) 2 (CIGSSe) solar cells. However, ITO is fabricated by sputtering method, which will increase the cost of CIGSSe solar cells and prevent its large-scale market applications in the future. Hence, it is particularly important to develop low-cost transparent conductive window layers to replace the traditional ITO. Silver nanowires (AgNWs) are considered to be the most promising alternative to ITO. Compared with sputtered ITO, AgNWs have the advantages of high transmittance, low cost, and easy fabrication. Nevertheless, the poor adhesion and stability of AgNWs can prevent the transportation of carriers of CIGSSe solar cells. Here, we select amorphous TiO x as an adjuvant to fabricate AgNWs/TiO x composite transparent conductive layer to substitute the traditional ITO. Under the assistance of TiO x matrix, not only the connection, adhesion, and stability of AgNWs are greatly enhanced, but also the surface roughness of AgNWs is also reduced. The influence of AgNWs concentration on the performance of CIGSSe solar cells is investigated. When the AgNWs concentration is 2.5 mg/mL, the transmittance and sheet resistance of AgNWs thin film are 93.35% and 93 Ω/sq, respectively, and the devices achieved the highest efficiency of 13.59%.

In this study, an Al-0.08Sn-0.08Ga-0.5Mg alloy was annealed at 200 °C–400 °C for 10 h. The microstructure and corrosion morphology of the Al anode were observed by scanning electron microscopy (SEM), and the effects of different annealing temperatures on the electrochemical properties of the Al anodes were studied by the hydrogen evolution rate, open circuit potential, Tafel curves, EIS and constant current discharge. The results show that the annealing treatment had a certain effect on the number and size of precipitates on the alloy surface, which improved the electrochemical activity and corrosion resistance of the Al alloy. Additionally, the Al–Sn–Ga–Mg alloy anode material has an excellent discharge performance in the actual use process when the annealing temperature is 350 °C, the related performance parameters were greatly improved compared with other annealing temperature conditions. The capacity density is 2670.99 mAh·g−1, and the energy density is 3379.15 mWh·g−1.

Achieving acidic seawater hydrogen production under commercial current densities remains a challenge. We present here a novel strategy through strong metal-support interaction (SMSI) and Pt-p-block alloys (PtM@CNT, M = Ga, In, Pb, and Bi) to construct a stable electronic perturbation and achieve acidic seawater hydrogen evolution performance at commercial current densities for the first time. SMSI stabilizes electronic perturbation and promotes durability up to 360 h. The optimized Pt 61 Ga 39 @CNT exhibits an overpotential of 18 mV at 10 mA cm −2 in 0.5 M H 2 SO 4 and maintains 360 h stability at 500 mA cm −2 in acidic seawater. Density functional theory (DFT) calculation reveals that the optimized d -band center of Pt and ΔG H* increase the catalytic activity, and the higher vacancy formation energy enhances the durability. Overall, this discovery not only first achieves stable acidic seawater hydrogen production under commercial current densities, but also opens a new opportunity to explore catalytic applications of p-block alloys and SMSI stabilized electronic perturbation.

Supported Pt-based bimetallic catalysts are representative types of dehydrogenation catalysts used for alkanes to olefins conversion. The platinum in these catalysts exhibits unique structural features accompanied with changes in electronic states due to the addition of the second metal. To investigate the impact of each effect on the activity for propane dehydrogenation , a series of Pt-M/SiO 2 (M= Fe, Cu, Ga, In and Sn) catalysts were prepared and used for propane dehydrogenation. Utilizing various characterization techniques, the geometric and electronic properties of these catalysts were studied. The relationships between the specific activity of bimetallic platinum catalysts in propane dehydrogenation and atomic sizes of alloys (i) and the total density of unoccupied d bands in platinum (ii) were considered. Via alloy formation, it was found that dilution of the active metal Pt occurred in these SiO 2 supported bimetallic catalysts, and the lattice parameter of Pt-M alloys decreased on Pt-Fe, Pt-Cu and Pt-Ga alloys, but increased on Pt-In and Pt-Sn alloys when compared with that of Pt foil. Catalytic activity was evidently shown to not be a function of the lattice parameters of Pt-M alloys, but appears closely related with the d -holes of Pt in Pt-M bimetallic catalysts. More d holes show favorably high activity. Among the studied Pt-M/SiO 2 (M= Fe, Cu, Ga, In and Sn) catalysts, the prominent and primary role of the electronic effect was demonstrated.

Three new metal borates, namely K0.5[B6O10]·H2O·1.5H3O (1), [GaB5O10]·H2en (2) and NaCs[Ga{B5O9(OH)}{BO(OH)2}] (3), have been synthesized under solvothermal conditions. Compound 1 features an intricate 3D framework composed of [B6O13]8− clusters, resulting in a 6-connected achiral pcu net. After introducing the organic gallium, one of the BO4 groups of the [B6O13]8− cluster is substituted by a GaO4 polyhedron to form the acentric [GaB5O13]8− cluster in 2. It also displays a high second-harmonic generation (SHG) response about approximately 2.6 times that of KH2PO4 (KDP), which is higher than those of alumino-borates (ABOs) containing the acentric [AlB5O13]8− cluster (0.3–2.1 times that of KDP). Dipole moment calculations have been carried out to confirm these results. In the process of trying to synthesize a new compound with a denser structure than 2, we have unexpectedly obtained 3 crystallized in the centrosymmetric (CS) space group, which shows a 1D structure constructed from the [Ga{B5O9(OH)}{BO(OH)2}]2− cluster. This kind of low-dimensional structure is rare in gallo-borates (GBOs) as well as ABOs.
