Article Abstract
The efficient oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) is achieved using the nano-CuO catalyst in a NaClO solution. This study reveals that the particle size of the nano-CuO can be effectively regulated by adjusting the calcination temperature, thereby significantly improving the catalytic performance of HMF oxidation to the desired product FDCA. Notably, the CuO-100 catalyst with the smallest particle size exhibits superior HMF conversion and maximum FDCA yield (96.0%). Moreover, even with a reduced NaClO/HMF molar ratio of 7.3:1 to improve the utilization of NaClO, the 94.7% yield of FDCA is obtained on the CuO-100 catalyst.

The sluggish kinetics and diffusion of lithium polysulfide (LiPS) intermediates lead to the decline in the capacity and rate of high-energy lithium-sulfur (Li-S) batteries. Integrating adsorbents and electrocatalysts into the Li-S system is an effective strategy for suppressing the polysulfide shuttle and enhancing the redox kinetics of sulfur species. The disordered structure of the electrocatalysts exhibits significantly enhanced catalytic activity.

The COVID-19 pandemic caused by the novel coronavirus SARS-CoV-2 has highlighted the critical need for safe and effective vaccines. In this study, subunit nanovaccine formulations were developed using the receptor-binding domain (RBD) of the SARS-CoV-2 spike (S) protein encapsulated in polymeric nanoparticles composed of poly(ethylene glycol)-block-poly(ε-caprolactone) (PEG-PCL). Two surfactants, poly(vinyl alcohol) (PVA) and sodium cholate (SC), were evaluated during formulation via a modified water-in-oil-in-water (w/o/w) emulsion-solvent evaporation method.

Maintenance of organismal function requires tightly regulated biomolecular communication. However, with aging, communication deteriorates, thereby disrupting effective information flow. Using information theory applied to skeletal muscle single cell RNA-seq data from young, middle-aged, and aged animals, we quantified the loss of communication efficiency over time.

Oxidative stress induces a wide range of cellular damage, often causing disease and cell death. While many organisms are susceptible to the effects of oxidative stress, haloarchaea have adapted to be highly resistant. Several aspects of the haloarchaeal oxidative stress response have been characterized; however, little is known about the impacts of oxidative stress at the translation level.

Carbon-11 (C)-labeled radiotracers are invaluable tools in positron emission tomography (PET), enabling real-time visualization of biochemical processes with high sensitivity and specificity. Among the various C synthons, cyclotron-produced [C]CO is a fundamental precursor, though its direct incorporation into complex molecules has traditionally been limited by its low reactivity, gaseous form, and short half-life. Recent advances in [C]CO fixation chemistry through both nonphotocatalytic and photocatalytic methods have significantly expanded its utility in the synthesis of structurally diverse compounds, including carboxylic acids, carbonates, carbamates, amides, and ureas.
