“…In GaCurNPs, the O 1s spectrum retains identical peaks but the peak gets broadened due to the Ga–curcumin interactions. It was reported that O 1s peaks of GaO(OH) (Ga–OH and Ga 3+ –O) also have their binding energy in this region . So, there will be possible overlapping of the O 1s peaks of GaCurNPs.…”

Combating antibiotic resistance has found great interest in the current clinical scenario. Pseudomonas aeruginosa , an opportunistic multidrug-resistant pathogen, is well known for its deadly role in hospital-acquired infections. Infections by P. aeruginosa are among the toughest to treat because of its intrinsic and acquired resistance to antibiotics. In this study, we project gallium–curcumin nanoparticle (GaCurNP) conjugates as a prospective candidate to fight against P. aeruginosa . The synthesized GaCurNPs were spherical with an average size ranging from 25–35 nm. Analysis by Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy deduced the nature of interaction between gallium and curcumin. Conjugate formation with gallium was found to improve the stability of curcumin at the physiological pH. When tested after 24 h of contact, at the physiological pH and 37 °C, the degradation of curcumin bound in the GaCurNPs was 26%, while that of native curcumin was 95%. The minimum inhibitory concentration (MIC) of GaCurNPs was found to be 82.75 μg/mL for P. aeruginosa ( ATCC 27853). GaCurNPs also showed excellent biofilm inhibition at 4MIC concentration. Raman spectroscopic analysis showed that GaCurNPs are capable of disrupting the cells of P. aeruginosa within 3 h of contact. Live/dead imaging also confirmed the compromised membrane integrity in cells treated with GaCurNPs. Scanning electron microscopy analysis showed membrane lysis and cell structure damage. The AlamarBlue assay showed that when L929 cell lines were treated with GaCurNPs with concentrations as high as 350 μg/mL, the cell viability elicited by the nanoparticles was 70.89%, indicating its noncytotoxic nature. In short, GaCurNPs appear to be a promising antibacterial agent capable of fighting a clinically significant pathogen, P. aeruginosa .

“…It is interesting that pure Ga metal also can be employed as the anode, which shows a theoretical capacity of 769 mA h g −1 (by the formation of Li 2 Ga alloy, as shown in Figure 4A). [63,65] Nevertheless, the melting point of Ga is 29.8°C; when it is directly used as the anode, it requires an operating temperature higher than room temperature, for example, more than 35°C. [66] Researchers have discovered that Ga-based alloys (such as GaInSn and GaSn) not only can maintain their fluidic status at room temperature but also have low toxicity.…”

Lithium‐ion batteries (LIBs) are one of the most exciting inventions of the 20th century and have been widely employed in modern society. LIBs have powered many of our electronics, such as laptop computers, smartphones, and even large‐scale energy storage systems. With the development of modern technology, next‐generation LIBs with higher energy density are in demand. A number of electrode materials with high theoretical capacity, including Sn, Si, Li metal anode, and S cathode materials, have been explored. Nevertheless, they usually suffer from structural or interface failure during cycling, limiting their practical application. Ga‐based liquid metals (LMs) possess self‐healing capability, fluidity, and metallic advantages so they have been employed as self‐healing skeletons or interfacial protective layers to minimize the negative impact of volume expansion or dendritic growth on the electrode materials. Herein, the features of Ga‐based LMs are briefly discussed to indicate their potential for battery systems. In addition, recent developments on Ga‐based LMs applied in LIBs have been summarized, including from the aspects of anodes, cathodes, and electrolytes. Finally, future opportunities and challenges for the development of Ga‐based LMs in LIBs are highlighted.

“…Other types of M-O-OH materials, including α-, γ-, ε-FeOOH, GaOOH, CoOOH, and MnOOH, have also been studied as anode materials for alkali-ion batteries. [225,[229][230][231][232][233][234] MnOOH has been used as an anode for alkali-ion batteries, which has a tunnel structure and conductivity higher than MnO 2 . The conductivities of MnOOH and MnO 2 are 10 4 -10 5 S cm −1 and 10 5 -10 6 S cm −1 , respectively.…”
