A novel fluorescent probe 2-(4-(diethylamino)-2-hydroxybenzylidene)-N-(2,3,3-trimethylbicyclo[2.2.1]heptan-2-yl)hydrazinecarbothioamide (HT) was prepared in this study by a condensation reaction. HT has been confirmed to possess high specificity toward Ga3+ over other metal ions (including Al3+ and In3+) via a distinct fluorescence light-up response. Moreover, HT exhibited good detection performances for Ga3+ including high selectivity, excellent anti-interference ability, a wide working pH range, and good reversibility. The association constant and limit of detection (LOD) were calculated to be 5.34 × 103 M−1 and 1.18 × 10−6 M, respectively. The detection mechanism of HT toward Ga3+ was proposed and confirmed by 1H NMR analysis, HRMS analysis, and DFT calculations. A simple test strip-based portable detecting device and a molecular INHIBIT logic circuit were established for improving its practical applicability. Furthermore, the desirable sensing performance of HT for Ga3+ was successfully reconfirmed in MCF-7 cells and zebrafish.

A new approach using water as the stripping phase for extraction and recovery of low-concentration Ga (III) from concentrated hydrochloric acid solutions by Aliquat 336-based supported liquid membrane (SLM) is suggested. Generally, the stripping of Ga (III) from the loaded organic phase during liquid-liquid two-phase stirring extraction using quaternary ammonium salt as an extractant is extremely difficult. However, in the present work, an efficient mass transfer of low-concentration Ga (III) through the SLM was observed by introducing a low acidity (pH=2) aqueous solution as the stripping phase of the SLM. It was revealed that dissociation of GaCl 4 - and HCl 2 - anions into Ga 3+ , Cl - and H + ions at the stripping/membrane phase interface play an important role in driving the mass transfer of GaCl 4 - from the concentrated hydrochloric acid solutions towards stripping phases. Kinetic analysis suggests that the permeability coefficient of Ga (III) ions through the SLM is dependent on the reaction temperature, extractant Aliquat 336 concentrations, and the difference in Cl - concentrations between the two sides of the liquid membrane phase , but independent of H + concentrations. In view of future’s applications for selective separation and recovery of low-concentration Ga (III) from the concentrated hydrochloric acid leaching solutions of various gallium-containing solid wastes, separation selectivity of Ga (III) against other coexisting metal impurity ions, such as Fe (II), Al (III), Mg (II) and Cu (II), was also evaluated.

Hydrogen peroxide (H 2 O 2 ) is a green oxidant that is widely used in daily life and industry. Artificial photocatalytic synthesis of H 2 O 2 is a green and sustainable scheme, but the high complexation rate of electron-hole pairs during photocatalysis and the low activation capacity of the catalyst for O 2 greatly inhibit the oxygen reduction reaction. Herein, the first synergistic modification of In 2 S 3 using ion doping and vacancy modulation is used in this paper. An In 2 S 3 -based photocatalyst containing S vacancies and Ga 3+ ions is designed and synthesized. After continuous irradiation under visible light ( λ ≥ 420 nm) for 1 h, the H 2 O 2 concentration of the system reaches 352.58 μmol L –1 , which is 7.5 times than that of pure In 2 S 3 , and the apparent quantum yield at 450 nm is 4.64%. Appropriate concentrations of S vacancies promoted O 2 adsorption, and theoretical calculations demonstrates that Ga 3+ ions and S vacancies synergistically promote O 2 activation and more favorable for 2e – oxygen reduction reaction. All these phenomena facilitate H 2 O 2 generation. Furthermore, ESR analysis and radical trapping experiments show that the interaction between superoxide anion radicals (•O 2 – ), singlet oxygen ( 1 O 2 ), h + , and proton donor (isopropanol) in the solution phase plays a key role in the photocatalytic synthesis of H 2 O 2 , which has been largely neglected in previous studies. We suggest that the S vacancy-regulated Ga 3+ ion-doped In 2 S 3 catalyst could provide a reference for the design of high-performance materials for the photocatalytic production of hydrogen peroxide.

Ga-based liquid metal (LM) suffers from severe corrosiveness toward chips and heatsink metals, posing a major obstacle to its practical use. Herein, we propose MXene films as barrier layers to mitigate Ga-induced corrosion. Combining first-principles density functional theory and experimental analyses, anti-corrosion performance and reliability were systematically evaluated. MXene nanosheets were found to self-assemble on Cu surfaces via van der Waals interactions, providing an interfacial adhesion force of 17.23 mN. The coatings effectively inhibit Ga corrosion while maintaining high thermal conductivity and long-term stability. This strategy offers a simple and efficient solution to corrosion issues in Ga-based TIM applications.

Rare earth (RE) dopants can modulate the bandgap of oxides of indium and gallium and provide extra upconversion luminescence (UCL) abilities. However, relevant UCL fine-tuning strategies and energy mechanisms have been less studied. In this research, InGaO, Ho3+ monodoped and Yb3+/Ho3+ codoped In2O3, and Ho3+ monodoped Yb3Ga5O12 nanoparticles (NPs) were synthesized by a solvothermal method. The effects of Yb3+ and Ho3+ dopants on the crystal structures, UCL properties, and optical bandgaps of the oxides were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UCL spectroscopy, and measurements of decay times, pump power dependence, and transmittance spectra. The crystal structures of oxide products of indium and gallium were significantly modified with RE dopants. In2O3 and Yb3Ga5O12 were selected as the host materials. For Yb3+/Ho3+ codoped In2O3 NPs, there existed energy transfers from the defect states of In2O3 to Ho3+ and from Yb3+ to Ho3+. With a fixed Ho3+ concentration, In2O3:0%Yb3+,2%Ho3+ NPs showed the optimal UCL properties mainly due to In2O3–Ho3+ energy transfer and Ho3+–Yb3+ energy-back-transfer, while with a fixed Yb3+ concentration, In2O3:5%Yb3+,3%Ho3+ NPs with a slight Yb2O3 impurity and Yb3Ga5O12:2%Ho3+ NPs did mainly due to Ho3+–Ho3+ cross-relaxation. Besides, the optical bandgaps of In2O3 and Yb3Ga5O12 were noticeably broadened with RE dopants. These findings can offer feasible directions for the synthesis and UCL fine-tuning of RE-doped oxides of indium and gallium and improve their multifunction application prospects in the fields of semiconductor and UCL nanomaterials.

Environment-friendly indium phosphide (InP)-based quantum dots (QDs) with efficient red-emitting properties are sufficiently needed to satisfy the requirement of burgeoning display and lighting technology. Currently, the syntheses of InP QDs using tris(trimethylsilyl)phosphine as the precursor are highly toxic and expensive. Herein, we successfully introduced gallium (Ga) ions into tris(dimethylamino)phosphine-based red InP cores through thermally-promoted cation exchange, and the obtained Ga-doped InP cores exhibited significantly increased photoluminescence quantum yields (PLQY) of up to 26%. The existence of Ga was directly confirmed by energy-dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy, and the functions of Ga were systematically studied. After subsequent coating of Ga-doped InP cores with ZnSeS and ZnS shells, the resulting Ga-InP/ZnSeS/ZnS QDs achieved a high PLQY of 62% with an emission maximum at 640 nm. In contrast, without Ga-doping, the PLQY only attained 36% using the same synthetic approach. This indicated an approximate 1.7-fold increase in PLQY. The enhancement of photoluminescence was related to the Ga 3+ , as it not only passivated surface defects of InP cores but also reduced core-shell interface stress. The Ga-InP/ZnSeS/ZnS QDs exhibited good stability towards heat treatment and ultraviolet (UV) irradiation. Moreover, the red light-emitting diode (LED) based on Ga-InP/ZnSeS/ZnS QDs performed well in a wide injected current range of 2 to 200 mA, with a maximum power efficiency of 0.68 lm/W. This work showcases Ga-doping through cation exchange as a promising strategy for enhancing the efficiency of InP-based red emitters.

A series of gallium-containing MFI zeolites were prepared via impregnation of conventional aluminosilicate ZSM-5 with Ga (Ga/ZSM-5) or hydrothermal synthesis of galloaluminosilicate (Ga–Al–Si) and gallosilicate (Ga–Si) MFI zeolites. These Ga-containing zeolites were then tested as the catalysts for co-feed catalytic fast pyrolysis (CFP) of pine wood and low-density polyethylene (LDPE) mixtures. Compared with conventional ZSM-5 zeolites, the Ga-containing MFI zeolites considerably increased the yields of valuable petrochemicals (monoaromatic hydrocarbons and olefins) and decreased the yields of undesired polyaromatic hydrocarbons and low-value alkanes from the co-feed CFP. In addition, Ga–Al–Si and Ga–Si zeolites generally produced both higher yields and selectivities for valuable petrochemicals (e.g., p -xylene and olefins) than Ga/ZSM-5 in the co-feed CFP. The results indicate that Ga-containing zeolites may be used to improve petrochemical production in co-feed CFP of biomass and plastics, and direct hydrothermal synthesis of Ga–Al–Si and Ga–Si MFI zeolites may provide a more convenient and better alternative to post modification of ZSM-5 with Ga to prepare Ga-containing zeolites for co-feed CFP.

A Ga-enriched ternary alkali-metal sulfide Na4Ga8S14 has been synthesized by a high temperature solid-state reaction. It crystallizes in the centrosymmetric Pbca (no. 61) space group with cell parameters a = 13.5260(4) Å, b = 11.4979(3) Å, c = 29.9592(9) Å, and Z = 8, and exhibits a three-dimensional (3D) network structure constructed from unique [Ga12S42] 12-membered rings, one-dimensional ∞[Ga4S11] chains, individual [GaS4] units and Na+ ions. The experimental band gap of Na4Ga8S14 was measured as ∼3.57 eV. Theoretical calculations indicate that the title compound is a direct band gap compound and the band gap is mainly determined by [GaS4] units. Meanwhile, statistical analysis shows that the atomic ratio N (N = AIAII/Ga, where AI = alkali-metal, AII = alkaline earth-metal) can be used to regulate the connection of [GaS4] units from zero-dimensional (0D) isolated groups, one-dimensional (1D) chains, and two-dimensional (2D) layers to 3D frameworks in Ga-containing alkali- and/or alkaline earth-metal chalcogenides. The results enrich the diversity of alkali-metal sulfides and give an insight into the structural regulation of alkali- and/or alkaline earth-metal chalcogenides.

Xinjiang is one of China’s most significant energy bases, and the generated fly ash (FA) contains a high concentration of metallic elements that can be used as a valuable resource. In this study, we looked into a roasting-acid leaching process technique for efficiently extracting gallium metal (Ga) from FA, employing sodium fluoride (NaF) as the roasting auxiliary and citric acid inzter (C6H8O7) acid leaching. After high-temperature activation by NaF, the glassy phase of FA was converted into silica aluminate with excellent acid solubility, and Ga was extracted from FA via acid leaching. The effects of optimal roasting and acid leaching process conditions on the Ga leaching rate were investigated. The results showed that it exhibited 83.71% Ga extraction under the conditions of a roasting temperature of 850 °C, FA-NaF coordination ratio of 1:0.5, roasting time of 10 min, C6H8O7solution concentration of 1.75 mol/L, ratio (S/L) of 1:15, acid leaching temperature of 100 °C, and acid leaching time of 1 h. The results also indicated that it was possible to obtain a higher extraction efficiency for the Ga extracts under the conditions of roasting temperature of 850 °C and FA-NaF coordination ratio of 1:0.5.

As strategic emerging industries represented by clean energy technologies develop rapidly, gallium (Ga), one of the critical elements due to its use in these technologies and limited supply, has attracted worldwide attention. The discovery of appropriate materials to adsorb Ga is crucial for improving the utilization of Ga resources. With the goal to recover Ga ions more efficiently and selectively, carbon nanotubes (CNTs) and amino-functionalized MIL-53 series metal–organic skeletons were hydrothermally synthesized into CNT/NH2-MIL-53(Fe) composite adsorbents. The composite's morphology, structure, chemistry and other physicochemical features were characterized, and the adsorption conditions including pH, initial Ga concentration, along with adsorbent dosage were optimized. The outcomes suggest that 2-CNT/NH2-MIL-53(Fe) performs better than the unmodified material in adsorption, and the theoretical maximum adsorption amount of Ga is 1483.8 mg g−1. The adsorption exhibited a single layer chemisorption with an endothermic spontaneous reaction. The adsorption mechanism for Ga onto 2-CNT/NH2-MIL-53(Fe) was mainly via ion exchange and chelation, accompanied by hydrogen bond interaction. The outstanding adsorption capacity and reproducibility using CNT/NH2-MIL-53(Fe) composites provide a novel method for adsorbing Ga from aqueous solutions.

Root architecture is the temporal and spatial configuration of root system in the heterogeneous matrix of soil that is prone to chemical stresses. Gallium (Ga) is among the emerging chemical pollutants that are mostly associated with high-tech industries, specifically associated with semiconductors. In view of its potential risk and increasing distribution in the environment, this study was designed to evaluate the inhibition rate, Ga distribution in different tissues, and root architecture of rice seedlings under different concentrations of Ga. We observed that 2.59, 46.7, and 168.2 mg Ga/L were minimum (EC 20 ), medium (EC 50 ), and maximum (EC 75 ) effective concentrations for rice plants that corresponded to the 20, 50, and 75% inhibition on the relative growth rate, respectively. Distribution of Ga in rice tissues showed that accumulation of Ga was much higher in roots than shoots of rice seedlings, and it increased with an increase in Ga doses. Evan blue staining technique reveals that the number of damaged/dead cell was dose-dependent on Ga. Moreover, several traits associated with root system architecture demonstrating that rice root system architecture altered in response to Ga stress. Collectively, the results reveal that Ga exposure inhibited the growth and development of rice plants. This study will enhance our understanding that how different concentrations of Ga in the environment can affect plants; however, more comprehensive studies are essential to further determine plant response against Ga stress.

BiFeO 3 -BaTiO 3 is a promising high-temperature lead-free piezo-ceramics due to its high Curie temperature ( T C > 500 °C) and excellent piezoelectric properties. However, a high leakage current was often detected in this system, which severely affects its applications. In this work, the 0.7BiFe (1− x ) Ga x O 3 -0.3BaTiO 3 (BFGa x -BT, 0.00 ≤ x ≤ 0.10) system was designed to reveal the reason of leakage-current density decreased by their leakage mechanism. Because of the suppression of generation of Fe 2+ and oxygen vacancy ( V O ∙ ∙ ), the leakage mechanism from space charge limited conduction mechanism found in Ga-free BF-BT ceramics turns into Ohmic conduction and Schottky emission mechanism as Fe 3+ was replaced with Ga 3+ . A good combination of piezoelectric properties ( d 33 = 174 pC N −1 and k p = 29%) and high Curie temperature ( T C = 497 °C) was achieved in the BFGa0.06-BT ceramic owning the lowest leakage-current density. This work will provide the clues for preparing the high insulation and high piezoelectric performance BF-BT-based ceramics by suppressing the valence change of Fe 3+ and V O ∙ ∙ appearance.
