Nickel-oxide embedded laser-induced graphene for high-performance supercapacitors.

This study explores the fabrication of nickel-oxide-embedded laser-induced graphene and its application in high-performance supercapacitors. Supercapacitors are critical for various applications due to their high power density and long cycle life. Nevertheless, they suffer from lower energy density compared to batteries.

Bacterial pore-forming toxin pneumolysin drives pathogenicity through host extracellular vesicles released during infection.

is a global priority respiratory pathogen that kills over a million people annually. The pore-forming cytotoxin, pneumolysin (PLY) is a major virulence factor. Here, we found that recombinant PLY as well as wild-type pneumococcal strains, but not the isogenic PLY mutant, upregulated the shedding of extracellular vesicles (EVs) harboring membrane-bound toxin from human THP-1 monocytes.

The effectiveness of Soxhlet extraction as a simple method for GO rinsing as a precursor of high-quality graphene.

Graphite-oxide (GO) is a valuable compound produced by the chemical oxidation of graphite. The procedure for converting graphite into GO includes two steps: oxidation and subsequent rinsing. Proper rinsing is essential to obtain processable and applicable graphite-oxide.

Surface modifications of carbon nanodots reveal the chemical source of their bright fluorescence.

Fluorescent carbon nanodots (CNDs) have drawn increasing attention in recent years. These cost-effective and eco-friendly nanomaterials with bright fluorescence have been investigated as promising materials for electrooptic and bioimaging applications. However, the chemical source stimulating their strong fluorescence has not been completely identified to date.

Zebrafish lipid droplets regulate embryonic ATP homeostasis to power early development.

In zebrafish embryos, the maternally supplied pool of ATP is insufficient to power even the earliest of developmental events (0-3 hpf) such as oocyte-to-embryo transition (OET). The embryos generate an additional pulse (2.5 h long) of ATP (1.

Turnover of the actomyosin complex in zebrafish embryos directs geometric remodelling and the recruitment of lipid droplets.

Lipid droplets (LDs), reservoirs of cholesterols and fats, are organelles that hydrolyse lipids in the cell. In zebrafish embryos, the actomyosin complex and filamentous microtubules control the periodic regulation of the LD geometry. Contrary to the existing hypothesis that LD transport involves the kinesin-microtubule system, we find that their recruitment to the blastodisc depends on the actomyosin turnover and is independent of the microtubules.
