Summary: In this work, gold nanoparticles (AuNPs) decorated Ti3C2Tx nanosheets (MXene/AuNPs composite) were successfully fabricated through self-reduction reaction. The obtained composite exhibited uniform dispersion of 23 nm AuNPs on Ti3C2Tx nanosheets, leading to a higher specific capacitance and cyclic stability in supercapacitor applications. The composite also showed promising potential as a candidate for integrated and flexible supercapacitors.

Summary: When the LA-ICP-MS analyses of pyrite show that the gold is held within the pyrite structure, it is often based on the observation that it plots below the gold solubility line on a gold vs. arsenic plot and exhibits relatively flat counts on laser ablation time-resolved output graphs. However, the study by Ehrig et al. (2023, this issue) demonstrates through LA-ICP-MS spot analyses, transmission electron microscopy, and electron backscatter diffraction that this interpretation is not always accurate. Additionally, they use these techniques to reveal the remobilization of trace elements, including gold, in pyrite during deformation and metamorphism.

Summary: This study developed a simple method for synthesizing fluorescent nanoparticles from fruit peels. Carbon dots (CDs) were fabricated from Annona squamosa (L.) peels using a carbonization technique. The synthesized CDs were confirmed to be fluorescent and capable of being absorbed by germinating mung bean seeds, indicating their potential use as a bioimaging agent. This novel method of synthesizing CDs was found to be eco-friendly, rapid, and cost-effective.

Summary: Water is essential for life on Earth and is used in everyday activities as well as major industrial applications. However, anthropogenic activities, such as agriculture and the textile industry, are leading to the release of harmful chemical effluents and dyes into water bodies, causing pollution and harm to the environment. Various remediation methods, including physical-chemical and biological methods, are being used, with a focus on bioremediation using microbes, algae, yeasts, enzymes, and plants. Remote sensing and GIS are being used for real-time management and maintenance of water quality.
