A simple one-pot synthesis of Ni nanoparticle/ordered mesoporous carbon composite electrode materials is demonstrated for electrosynthesis for the first time. The obtained nanocomposites have uniform mesopore sizes (3.0-3.7 nm), large specific surface areas (506-633 m g), high pore volumes (0.28-0.38 cm g), well-graphitized carbon frameworks, and uniformly dispersed Ni nanoparticles (7-15 nm) embedded in the carbon pore walls. The prepared materials show very high performance in the selective (∼84%) electrocatalytic reduction of aromatic ketones into alcohols (∼79%).

Nanographenes and polycyclic aromatic hydrocarbons exhibit many intriguing physical properties and have potential applications across a range of scientific fields, including electronics, catalysis, and biomedicine. To accelerate the development of such applications, efficient and reliable methods for accessing functionalized analogs are required. Herein, we report the efficient synthesis of functionalized small nanographenes from readily available iodobiaryl and diarylacetylene derivatives a one-pot, multi-annulation sequence catalyzed by a single palladium catalyst.

Tunable optical properties exhibited by semiconductor nanocrystals (NCs) in the near infrared (NIR) spectral region are of particular interest in various applications, such as telecommunications, bioimaging, photodetection, photovoltaics, . While lead and mercury chalcogenide NCs do exhibit exemplary optical properties in the NIR, Cu-In-Se (CISe)-based NCs are a suitable environment-friendly alternative to these toxic materials. Several reports of NIR-emitting (quasi)spherical CISe NCs have been published, but their more complex-shaped counterparts remain rather less explored.

Polysaccharide-based metal-organic frameworks have attracted widespread attention due to their combination of the biocompatibility and flexibility of polysaccharides. Cyclodextrin are interesting bio-ligands in the construction of polysaccharide-based MOFs. Conventional methods for preparing cyclodextrin metal-organic frameworks (CD-MOFs) are often time-consuming and inefficient.

Lignocellulosic biomass-based plastics provide a sustainable alternative to petroleum-based plastics by converting agricultural by-products into value-added materials, promoting a circular economy. This study investigates the development of thermoplastics from sugar beet pulp (SBP), a by-product rich in cellulose and pectin. A one-pot direct transesterification process was used to fully substitute hydroxy groups in SBP with acyl chains of varying lengths (C2-C10), achieving up to 96 % substitution.

Cuproptosis shows great prospects in cancer treatments. However, insufficient intracellular copper amount, low-level redox homeostasis, and hypoxic tumor microenvironment severely restrict cuproptosis efficacy. Herein, hydrazided hyaluronan-templated decorated CuO-doxorubicin (CuDT) nanodot clusters (NCs) are developed for efficient doxorubicin (DOX)-sensitized cuproptosis therapy in breast cancer via a three-pronged strategy.
