Summary: This study evaluated the corrosion inhibition properties of a ligand and mixed metal oxide nanocomposite and characterized them using various physicochemical techniques. The electrochemical studies revealed that an epoxy coating of mixed metal oxides with a concentration of 0.8 ppm exhibited excellent corrosion protection. SEM images confirmed the anti-corrosive behavior of the synthesized compounds, suggesting that the prepared material could be a next-generation tool for sustainable anti-corrosive coatings.

Summary: Metal-based nanoparticles can act as effective antiviral agents against various types of viruses. Their antiviral activities can be modulated by different preparation methods and surface modifications. These nanoparticles can be used as aqueous dispersions or incorporated into composite materials. The major antiviral mechanisms include disrupting viral attachment, generating reactive oxygen species, and inactivating viral glycoproteins. The physicochemical properties of the nanoparticles, such as size and surface modification, play a role in their antiviral efficacy.

Summary: The article introduces a simple and versatile strategy that allows for the retention of individual gold nanoparticles on a substrate, enabling single-nanoparticle nanomachining. This method involves the formation of a carbon protective layer on individual nanoparticles via electron-beam irradiation, selective removal of unprotected nanoparticles using a corrosive agent, and subsequent elimination of the carbon layer. This enables the fabrication of a single micrometer-long uniform through nanochannel in the silicon wafer, which can be employed for nanopore sensing and shape-based nanoparticle distinguishing.

Summary: Magnetic iron oxide nanoparticles have broad potential applications in medical and biological sciences. They can be used in targeted drug delivery, internal radiotherapy, magnetic resonance imaging, hyperthermia, and radiolabelling. The appropriate design of nanoparticles allows them to be delivered to desired tissues and organs, with an external magnetic field increasing their biodistribution. Factors such as size, shape, surface charge, coating molecules, and route of administration affect their biodistribution. Modern techniques can determine nanoparticle accumulation sites and concentration in isolated tissues or the body in vivo.

Summary: An Li92.5Cu5Ag2.5 alloy anode with controlled lithiophilic/lithiophobic gradients was designed for bottom-up Li deposition. The inert metal Cu provided structural stability, while the lithiophilic metal Ag offered abundant Li deposition sites. This ultrathin Li-rich composite anode exhibited stable cycling over 1200 h, with a low Li content of 10 mA h cm(-2).

Summary: This study utilizes branched polyethyleneimine as a functional binder to address the electrode deterioration and capacity decay caused by the dissolution of transition metal ions. The binder can effectively absorb soluble transition metal ions, reduce the loss of active materials, and achieve uniform distribution of key components. This leads to improved rate capability and cycle stability of the battery.

Summary: Undoped and Ca-doped ZnO nanoparticles were synthesized via hydrothermal method. The influence of Ca doping ratio on the physical properties of ZnO nanoparticles was investigated by varying the Ca doping ratio. XRD and SEM techniques were used for structural and morphological characterization, while transmittance measurements were used for optical characterization. It was found that the introduction of Ca in the ZnO network enlarged the crystallographic parameters, created tensile strain, and increased the crystallite size. The prepared nanopowder showed homogeneously distributed spherical grains with increasing Ca doping ratio. The optical band gap of Ca-doped ZnO decreased due to the increase in crystallite size and disorder creation.
