With the development of molecular biology and pharmacology, proteins have been considered essential therapeutic agents that directly or indirectly participate in disease treatment. However, protein-based formulations face significant drawbacks, including low storage stability, rapid metabolism in vivo, and limited organ-selective delivery. Moreover, the internal protein also participated in drug transportation and cellular endocytosis.

This study investigates the spatio-temporal dynamics and spatial correlations of GTI and air pollution across China's major river basins, with a particular focus on differentiating the roles of GTI quantity and quality. Using the extended STIRPAT and spatial Durbin models, we examine nonlinear relationships, basin-specific heterogeneity, and spatial spillover effects.

The experimental results showed that lipase N showed enhanced activity, while lipase P showed reduced activity under identical ultrasound conditions. Furthermore, the of lipase N increased and the free energy (Δ) decreased, whereas lipase P showed the opposite change.

Multidrug resistance (MDR), the major mechanism by which various cancers develop specific resistance to therapeutic agents, has set up enormous obstacles to many forms of tumor chemotherapy. Traditional cocktail therapy administration, based on the combination of multiple drugs for anti-MDR chemotherapy, often suffers from inconsistent pharmacokinetic behaviors that cannot act synchronously on the lesions, leading to limited pharmacodynamic outcomes. Despite the emergence of nanomedicines, which has improved chemotherapeutic drugs' bioavailability and therapeutic effect on clinical application, these monotherapy-based nano-formulations still show poor progression in overcoming MDR.

Ultrathin nanofibrous films with unique properties, such as controlled thickness, structures, and excellent mechanical robustness, play a vital role in flexible wearable devices, electronic skin, and rechargeable batteries. However, nanofibrous films are always facing limitations in their mechanical properties, even though they are strong when used as textiles, mainly owing to their structural shortcomings by using conventional fabrication methods. Herein, we present the fabrication of free-standing ultrathin nanofibrous films with good mechanical properties by using a microfluidic-based continuous printing strategy.

This study presents a technique for processing transparent glass and resin substrates using a low-cost laser marker to create a micro-nano-structured surface with exceptional anti-fog properties. The approach involved depositing an aluminum (Al) film on the transparent substrates as an absorbing layer, followed by rapid laser marker ablation. This ablation process effectively removed the majority of the Al film, resulting in the formation of hierarchical hillock-hollow micro-structures and the dispersion of Al-based nano-particles throughout the surface.

Herein, a bifunctional superaerophilic/superaerophobic (SAL/SAB) NiFe layered-double-hydroxides (LDHs) electrode has been developed, which can drive H and O bubbles out of the reaction system by asymmetric Laplace pressure and accelerate dissolved gases diffusion through reducing their diffusion distance. Consequently, the SAL/SAB NiFe-LDHs electrode exhibits excellent HER activity with an overpotential of -76 mV at -10 mA cm and outstanding oxygen evolution reaction activity with an overpotential of 253 mV at 100 mA cm.

Silk nanofibers (SNF) have great applications in high-performance functional nanocomposites due to their excellent mechanical properties, biocompatibility, and degradability. However, the preparation of SNF by traditional methods often requires the use of some environmentally harmful or toxic reagents, limiting its application in green chemistry. In this paper, we successfully prepared SNF using natural silk as raw material and solvent stripping technology by adjusting the solvent concentration and solution ratio (the diameter of about 120 nm).
