Summary: The durability of RuO2 as an acidic oxygen evolution reaction catalyst can be significantly improved by pretrapping RuCl3 precursors within a cage compound possessing 72 aromatic rings, leading to well carbon-coated RuOx particles (Si-RuOx@C) after calcination. The catalyst exhibits excellent catalytic activity and stability during OER, while RuOx prepared from similar non-tied compounds does not show such performance.

Summary: This study investigates the changes in microbial and zinc concentration in Tilapia mince fortified with zinc oxide nanoparticles during storage. The results show that the samples treated with ZnO nanoparticles have the lowest microbial count, indicating a significant antimicrobial effect. The fortified samples also meet the dietary requirement for zinc and can provide more than the recommended daily intake for adults. This suggests that fortifying Tilapia mince with zinc can improve its shelf life and help eradicate zinc deficiency.

Summary: This paper presents and discusses a hydrothermal method for obtaining nano zinc oxide doped with different contents of aluminum ions (III). The synthesis precursor used was a mixture of Zn(NO3)(2)*6H(2)O and Al(NO3)(3)*9H(2)O salts in aqueous solution. All reactions were performed in a microwave reactor to reduce process time. The influence of process parameters and impurity ion content on the properties of the synthesized nano zinc oxide were analyzed. In addition to zinc oxide doped with Al(III) ions, a spinel phase (ZnAl2O4) was also obtained. The luminescent properties of the nano zinc oxide were discussed in relation to the dopant ions. The results showed that the luminescence intensity decreases with increasing dopant content. The obtained materials are intended for use as luminescent materials in optoelectronics and sensors.

Summary: To combat pathogens or tumors, antimicrobial or antineoplastic drugs have been developed, however, cells have evolved mechanisms to resist such drugs. Microorganisms or cancer cells that exhibit resistance to multiple drugs are known as multidrug-resistant (MDR) cells. The drug resistance status of a cell can be determined through analyzing genotypic and phenotypic changes caused by physiological and biochemical alterations. Conventional methods for determining drug resistance status have drawbacks, and biosensors with low detection limit have been engineered as an alternative solution.

Summary: In this study, reduced graphene oxide (RGO) nanoparticles were synthesized using modified Hummer's technique and characterized by XRD, Raman spectroscopy, SEM, and TEM. Raman spectra revealed the D-band at 1354 cm(-1) and G-band at 1606 cm(-1) of RGO. TEM analysis confirmed the nanoscale structure of RGO. The prepared nanoparticles were mixed with alcohol and coated onto a standard Copper electrode for experimentation on EDM. The influence of process parameters, such as current, pulse on, and pulse off, on the material removal rate was studied using Taguchi Technique and Minitab18.0. Significant improvement in material removal rate was observed at a current of 20 amperes, pulse on time of 90 microseconds, and pulse off time of 1 microsecond. It was found that current and pulse off were the significant factors affecting the material removal rate.
