Herein, it was used as the main scaffold to prepare wound dressings for treating diabetic skin wounds. Polypyrrole (PPy) was first synthesized by in situ oxidative polymerization within BC membrane and applied as a photothermal agent, followed by coating with chitosan (CS) to improve the biocompatibility and antibacterial properties.

Collective Magnetism of Spin Coronoid via On-Surface Synthesis.

Polyradicals obtained from open-shell coronoids hold promise for applications in spintronics and quantum technologies due to the strong interactions between spins in fully fused cyclic systems. Coronoid synthesis has long been considered difficult due to the cyclization of nanographene. It becomes an immense challenge to synthesize open-shell coronoids since radicals appear only when the macrocycle size exceeds a critical value.

NAD modulation with nicotinamide mononucleotide coated 3D printed microneedle implants.

Nicotinamide adenine dinucleotide (NAD) deficiency has been shown to cause pathogenesis of age-related functional decline and diseases. Investigational studies have demonstrated improvements in age-associated pathophysiology and disease conditions. However, invasive methods such as immunohistochemistry, metabolic assays, and polymerase chain reaction currently used to measure cell metabolism render cells unviable and unrecoverable for longitudinal studies and are incompatible with dynamic observations.

Intermediate-Controlled Synthesis of Quasi-2D (PEA)MAPbI in the 20-30% Relative Humidity Glovebox Environment for Fabricating Perovskite Solar Cells with 1 Month Durability in the Air.

Herein, quasi-two-dimensional (Q-2D) (PEA)MAPbI (prepared by a two-step process) and hole transport layer of a solar cell were fabricated in a high relative humidity (25 ± 5%) environment. The PSC behavior of most Q-2D perovskites is worse than that of three-dimensional perovskites owing to the horizontal alignment of the innate characteristic organic plates on the substrate. Using hybrid immersion solvents (HISs), we have improved vertical alignment in an appropriate ratio to enhance the efficiency of charge transfer and the high coverage of the first priming layer (first step).
