Ti 3 C 2 T x MXenes have emerged as promising candidates for energy storage applications due to their two-dimensional structure, metallic conductivity, tunable surface functionalities, and intrinsic pseudocapacitive charge storage. This study explores the hydrothermal synthesis of GaOOH/Ti 3 C 2 T x composites using gallium nitrate as the gallium precursor. The incorporation of GaOOH not only expands the interlayer spacing of Ti 3 C 2 T x , facilitating more efficient electrolyte ion migration, but also enhances the material's energy storage capacity by introducing additional active sites and augmenting pseudocapacitance. As an electrode material in supercapacitors, GaOOH/Ti 3 C 2 T x composites, prepared with a 0.06 M gallium source concentration, achieve a remarkable specific capacitance of 542.1 F·g −1 , surpassing that of pristine Ti 3 C 2 T x (305 F·g −1 ), with a minimal degradation of only 3.4 % after 5000 charge-discharge cycles. This research offers valuable insights into the electrochemical behavior of GaOOH/Ti 3 C 2 T x composites and highlights the role of GaOOH in enhancing the performance of these materials. The results underscore the potential of combining metal hydroxides with MXenes for advanced supercapacitor applications.

M-gallate (M = Ni, Co) coated stainless steel meshes (SSMs) were fabricated through a cost-effective and environmentally friendly synthesis approach of electrodeposition for a sustainable solution of oil/water separation. The M-gallate/500-mesh, synthesized in just 120 s, exhibit super hydrophilic properties owing to the rich hydroxyl groups (–OH) inherent in their metal–organic framework (MOF) structure which significantly enhance their performance in oil/water separation. The nano-sized randomly oriented crystals growth of Co-gallate/500-mesh showed the excellent separation performance with a water flux of 93.3 ± 5.2 × 10 3 Lm −2 h −1 and separation efficiency of 99.8 ± 0.1 % while Ni-gallate/500-mesh exhibit a water flux of 71.5 ± 5.9 × 10 3 Lm −2 h −1 and separation efficiency of 99.6 ± 0.2 % for the separation of light oil toluene/water mixture. To assess practical applicability, the M-gallate/500-mesh were tested for seawater/oil mixtures. Notably, the separation efficiency remained above 99 % for both Ni-gallate/500-mesh and Co-gallate/500-mesh while the seawater flux slightly increased for Ni-gallate/500-mesh. Moreover, M-gallate/500-mesh demonstrated good separation performance and chemical stability under alkaline conditions coupled with rapid and facile synthesis, indicating their potential for practical oil/water separation.

With the growing demand for highly efficient sensors capable of rapid and reliable detection of trap states in semiconductors, developing novel chemical and physical phenomena induced by trap states at nanomaterial interfaces has thus emerged as a critical technological field. Herein, we developed an innovative time-dependent chemiluminescence (CL) method for evaluating trap states in semiconductor materials. By leveraging the unique trap states of Cr3+-activated zinc gallate (ZGOC) semiconductors and the hydroxyl radical (·OH)-rich EDTA-Fe2+-H2O2 system, we achived rational manipulation of ·OH-triggered time-dependent near-infrared (NIR) CL induction. To extract high-information-density outputs from the CL response, ZGOC nanocrystals associated with different Cr3+-related trap states were precisely identified by a distinct CL “fingerprint” pattern and robust statistical analysis. Remarkably, the generalizability of this method was validated using mixed models containing two typical samples and other adjustable ZGOC systems. The developed CL probe for Cr3+-related trap state evaluation provides advantages such as cost-effectiveness, operational simplicity, and rapid response, offering a promising and innovative alternative to conventional trap state assessment methods.

Liquid metallic gallium demonstrates a great potential as a reactive cathode with an excellent characteristic for the effective separation of fission products in the recovery of spent nuclear fuel in the “liquid metal-salt melt system”. Advanced electrochemical methods were utilized to investigate the deposition mechanism of Er(III) ions, along with the kinetic and thermodynamic properties of Er(III) ions on both an inert molybdenum (Mo) electrode and a liquid gallium (Ga) electrode. The results indicate that the reduction reaction of Er(III) belongs to a one-step of process involving the transfer of three electrons and the process is reversible within the range of scanning rates investigated on an Mo electrode. The diffusion coefficients at different temperatures were calculated on inert Mo electrode, and the activation energy of diffusion process was calculated to be 33.38 kJ mol-1. Subsequently, the electrochemical co-deposition of Ga(III) and Er(III) ions on an inert Mo cathode and the reduction of Er(III) ions on reactive Ga cathode were investigated, and the electrochemical mechanisms of the two reaction types were determined. Additionally, the oxidation-reduction potentials of the Er-Ga intermetallic compounds that may be appeared during the reaction were determined. The main thermodynamic properties of Er-Ga alloy were obtained by open circuit potentiometry, then the separation factors of U/Er couple were explored. Meanwhile, Er was effectively extracted as ErGa6 through potentiostatic electrolysis at -2.0 V for 12 h, achieving an extraction rate of approximately 98.3%.

With the rise of antibiotic-resistant bacteria, non-antibiotic therapies like gallium gain increasing attention. Intravenous gallium nitrate is under Phase II clinical trials to treat chronic Pseudomonas aeruginosa infections in cystic fibrosis patients. However, its clinical efficacy is constrained by the achievable peak concentration in human tissue. To address this limitation, we apply a genome-wide CRISPR interference approach (CRISPRi-seq) to identify potential synergistic targets with gallium. We classify the essential genes by response time and growth reduction, pinpointing the most vulnerable therapeutic targets in this species. In addition, we identify a highly conserved gene, fprB , encoding a ferredoxin-NADP⁺ reductase, whose deletion sensitizes P. aeruginosa to gallium, lowering its MIC by 32-fold and shifting mode of action from bacteriostatic to bactericidal. Further investigation reveals that FprB plays a critical role in modulating oxidative stress induced by gallium, via control of iron homeostasis and reactive oxygen species accumulation. Deleting fprB enhances gallium’s efficacy against biofilm formation and improves outcomes in a murine lung infection model of P. aeruginosa , suggesting FprB is a promising drug target in combination with gallium. Overall, our data show CRISPRi-seq as a powerful tool for systematic genetic analysis of P. aeruginosa , advancing the identification of novel therapeutic targets.

Terahertz (THz) fingerprint metasensing is an effective method for identifying biological substances, offering advantages such as high efficiency and non-destructiveness. Currently, one important approach to achieving THz fingerprint spectrum sensing is the design of THz metasurface (MS) sensors with broad spectral coverage and multiple resonant peaks. However, there is still exhibit potential for further enhancement in the sensitivity, selectivity, and detection limits of THz sensors. Gallium nitride (GaN), with its exceptional optoelectronic properties such as high carrier concentration, high mobility, and excellent chemical stability, can be integrated with THz MSs to create high-performance sensors. In this study, we propose a THz MS biosensor coated with GaN. Since different analytes exhibit distinct absorption characteristics in the THz range, preliminary identification of various substances can be achieved by analyzing differences in the trends of spectral amplitude changes. Experimental results demonstrate that the proposed metasensor achieves a detection limit of 1 μg/mL for bovine serum albumin (BSA) and 10 pg/mL for creatinine. Through radar chart analysis, the transmission spectra of the metasensor show significant differences when detecting creatinine and BSA, indicating its capability to effectively identify different analytes. The GaN metasensor developed in this study provides a highly sensitive and broadly spectrally covered solution for THz fingerprint spectrum analysis, which holds potential applications in assessing kidney function and health status.

Tandem structures with different subpixels are promising for perovskite-based multicolor electroluminescence (EL) devices in ultra-high-resolution full-color displays; however, realizing excellent luminance- and color-independent tunability considering the low brightness and stability of blue perovskite light-emitting diodes (PeLEDs) remains a challenge. Herein, a bright and stable blue gallium nitride (GaN) LED is utilized for vertical integration with a green MAPbBr 3 PeLED, successfully achieving a Pe-GaN tandem LED with independently tunable luminance and color. The electronic and photonic co-excitation (EPCE) effect is found to suppress the radiative recombination and current injection of PeLEDs, leading to degraded luminance and current efficiency under direct current modulation. Accordingly, the pulse-width modulation is introduced to the tandem device with a negligible EPCE effect, and the average hybrid current efficiency is significantly improved by 139.5%, finally achieving a record tunable luminance (average tuning range of 16631 cd m −2 at an arbitrary color from blue to green) for perovskite-based multi-color LEDs. The reported excellent independent tunability can be the starting point for perovskite-based multicolor EL devices, enabling the combination with matured semiconductor technologies to facilitate their commercialization in advanced display applications with ultra-high resolution.

To explore the effect of B-site ion variation in the garnet structure on the microwave dielectric properties, we introduced part of Y 3+ into Y 3 Ga 5 O 12 to form a series of Y 3 (Y x Ga 2- x )Ga 3 O 12 ( x = 0–0.9) ceramics. Rietveld refinements, based on the XRD data, reveal that the Y 3+ x Ga 5- x O 12 ( x = 0–0.8) ceramics crystallized in the garnet structure with the Ia -3 d space group, and two phases simultaneously coexisted in the x = 0.9 ceramics. The average B-site cations were compressed, A-site cations exhibited rattling, and the overall structure of Y 3+ x Ga 5- x O 12 ( x = 0–0.8) slightly expanded. As the concentration of Y 3+ at the B-site increased in pure-phase ceramics, the ε r (12.15–12.79) and τ f (−69.95 ∼ −60.72 ppm/°C) exhibited an upward trend, while the Q × f descended (101,902–79,209 GHz). The factors influencing the microwave dielectric properties were further examined by considering the ionic polarizability, bond valence, lattice energy, and packing fraction.

The first part of the study is devoted to the comparison between the doping effect of urea (a small molecule) and polyethylene glycol (PEG, a long-chain polymer) on the physical property of metallic gallium (Ga). The physical properties of the Ga composited in the two materials, Ga/urea and Ga/PEG, were investigated by scanning electron microscopy, X-ray powder diffraction, X-ray photoelectron spectroscopy, differential scanning calorimetry, superconducting quantum interference device, and surface-enhanced Raman scattering spectra and compared with our previous results for the effect of macrocyclic hosts (e.g., cyclodextrins, calixarenes) on the physical modification of metallic Ga. Our data provide new direct evidence that the modification of physical properties of Ga is highly dependent on the nature of dopants used. For example, the addition of a small amount of urea causes a fundamental change in the crystallization behavior of Ga, and the presence of PEG results in the occurrence of a weak paramagnetism of Ga at high fields, both of which are completely different from the effect of other dopants. The other part of the study is devoted to demonstrating whether there is a significant difference in the oxidation process of metallic Ga and its composites. Our result gives a strong positive answer to the question. β- and γ-gallium oxide nanocrystals were obtained by sintering the Ga/urea composite at different temperatures and exhibited distinctive photoluminescence and photocatalysis properties. These results gave a strong impression that the introduction of different dopants leads metallic Ga to generate different features in microstructure, physical property, and especially chemical reactivity. We believe that the findings of this study have important implications for the development of inorganic materials.

Reported powdery adsorbents with poor adsorption efficiency and stability make it imperative to develop novel materials to extract gallium ions (Ga(III)) from effluents. Herein, UiO-66-NH 2 -based mixed matrix membranes (TPU/0.1THB/U6N-1.5 MMMs) via electrospinning is firstly reported for separation and recovery of Ga(III). TPU/0.1THB/U6N-1.5 MMMs efficiently overcomes multiple bottlenecks of powder UiO-66-NH 2 , including poor stability, reusability and adsorption capacity. Its maximum adsorption for Ga(III) is 96.18 mg·g −1 at pH 10.0. It has superiority in selective adsorption of Ga(III) from Al(III), Cu(II), Zn(II), Co(II) coexistence solution. Adsorption capacity of TPU/0.1THB/U6N-1.5 for Ga(III) reaches more than 80% after 9 cycles. Specially, it still retains excellent mechanical strength, flexibility and structural integrity after 12 h filtration, or after 9 adsorption-desorption cycles, even soaked in 5 mol·L -1 HCl for a week. TPU/0.1THB/U6N-1.5 MMMs also improves the problem of low water flux. TPU/0.1THB/U6N-1.5 with high MOFs loading possess high water flux of 382.2 L·m −2 ·h −1 with a permance of 382.2 L·m −2 ·h −1 ·bar −1 and rejection rates of 90% for Ga(III). The main adsorption mechanism of TPU/0.1THB/U6N-1.5 is based on the chelation between phenolic hydroxyl groups of MMMs and Ga(III) at pH 10.0. Overall, the as-prepared TPU/0.1THB/U6N-1.5 has potential for water treatment through the process of membrane adsorption.

The transport of Ga(III) from chloride solution by supported liquid membrane (SLM) using organophosphorus acids as carriers was studied and compared with solvent extraction results. The diffusion coefficient, permeability coefficient and mass transfer resistance for both processes were analyzed by investigating various parameters, such as flow pattern, flow rate, pH, Ga(III)/extractant concentration and temperature. Under optimized conditions, the extraction percentage of 97.0% and permeability coefficient of 9.22 × 10−6 m/s was achieved for SLM process. Kinetic modeling was proposed to determine the mass diffusion coefficient of Ga(III) complex across the membrane and stability of this SLM system was also examined.

The effects of substitution of BaF2 for BaO on physical properties and 1. 8 μm emission have been systematically investigated to improve spectroscopic properties in Tm3+ doped gallium tellurite glasses for efficient 2.0 μm fiber laser. It is found that refractive index and density gradually decrease with increasing BaF2 content from 0 to 9 mol.%, due to the generation of more non-bridging oxygens. Furthermore, OH− absorption coefficient (αOH) reduces monotonically from 3.4 to 2.2 cm−1 and thus emission intensity near 1.8 μm in gallium tellurite glass with 9 mol.% BaF2 is 1.6 times as large as that without BaF2 while the lifetime becomes 1.7 times as long as the one without BaF2. Relative energy transfer mechanism is proposed. The maximum emission cross section and gain coefficient at around 1.8 μm of gallium tellurite glass containing 9 mol.% BaF2 are 8.8 × 10−21 cm2 and 3.3 cm−1, respectively. These results indicate that Tm3+ doped gallium tellurite glasses containing BaF2 appear to be an excellent host material for efficient 2.0 μm fiber laser development.
