Summary: This study shows that the stability of protein substrates in the GroEL/ES chaperonin cage is dramatically reduced, partially due to a diminished hydrophobic effect. The reduced hydrophobic effect is likely caused by water ordering due to a small number of hydration shells between the cavity and protein substrate surfaces.

Summary: An enzyme grafting strategy was used to create a metal-organic capsule-docking artificial enzyme that bypasses the need for cofactor shuttling and regeneration. This semi-artificial enzyme efficiently converts various types of alcohols to amine products in aqueous/organic solutions and Escherichia coli, offering opportunities for sustainable and environmentally friendly biomanufacturing.

Summary: Experimental results showed that when the laser energy exceeded 80 mJ, the spectral line intensity of confined plasma was significantly enhanced at a delay time of 8-14 μs, with a higher energy leading to a greater enhancement effect. Confined plasma within a hemispherical cavity could maintain a relatively high temperature for an extended period, resulting in prolonged spectral enhancement.

Summary: In this study, the concept of "particle in a box", widely developed in semiconductor quantum dot research, was extended into mid-infrared (IR) cavity modes with lateral confinement in an optical cavity. The resulting quartet of polariton states, formed by the hybridization of discrete cavity modes with molecular vibrational modes, can support multiple coherence states in the IR regime. Through tailored pump pulse sequences, these coherences were selectively prepared and the existence of multiple coherences was verified. The simulation based on Lindblad equation demonstrated that the quartet of polariton states residing in the same cavity were specifically robust against decoherence caused by fluctuations in space. The presence of multiple robust coherences lays the foundation for entangled states and coherent interactions between cavity polaritons, which is crucial for advancing polariton-based quantum information technology.

Summary: The tumor microenvironment is immunosuppressive, hindering antitumor immune responses. However, pathogenic microorganisms can trigger strong immune responses. In this study, protein nanocages called CpG@HBc NCs were developed to deliver immunostimulatory agents and effectively reverse the suppressive tumor microenvironment, inhibiting poorly immunogenic tumors in mice. CpG@HBc NCs induced significant alterations in immune responses and sensitized colorectal cancer tumors to T cell immune responses, resulting in tumor growth inhibition and immune activation.

Summary: This study investigates the heat/mass transfer on the bottom surface of a rectangular cavity in an incompressible turbulent boundary layer flow. The effects of cavity width to depth ratio are examined, and the results show that the transfer decreases as the width is reduced, regardless of the Reynolds number. The computational model is able to predict the transfer accurately for larger cavity widths, but performs poorly for smaller widths.

Summary: Graphene, a carbon allotrope, has unique physicochemical and biological properties, making it a promising material for the synthesis of topical remedies. In this study, graphene nanoplatelets were embedded into a polymeric solution and fabricated into a scaffold. The fabricated scaffold exhibited desirable hydrophilicity and swelling index, making it suitable for topical applications.

Summary: We conducted Monte Carlo simulation on a simple model to study the arrangement of multiple rigid rods confined within a rigid spherical cavity under crowded conditions. Depletion forces are essential for rods shorter than the cavity's radius, which distribute around the cavity boundary with low orientation ordering in the presence of rigid crowders. For rods longer than the cavity's radius, they form a bundle inside the cavity and exhibit nematic ordering with increasing levels of crowding. The formation of nematic order is entropically favorable, allowing more free space for crowders to distribute around the cavity boundary. These findings are consistent with experimental results in previous literature.

Summary: Excessive heavy metals in pig feed pose a significant threat to pigs' health, meat quality, humans consuming the meat, and the environment. This paper introduces and investigates a method to improve the detection of copper in pig feed using laser-induced breakdown spectroscopy (LIBS) combined with cavity-confinement and microwave-assistance. The results show that the combined approach enhances the spectral intensity and signal-to-noise ratio for copper detection in pig feed, providing theoretical guidance for rapid characterization and improvement of pig feed.

Summary: This study investigates convective heat transfer from the bottom surface of rectangular cavities. The results show that the cavity width significantly affects the distribution of heat transfer coefficient on the bottom surface, and three-dimensional effects emerge as the cavity width decreases. Detailed spatial distributions of heat transfer coefficient are obtained using a mass transfer technique and numerical simulations.

Summary: Fusion occurs when light nuclei combine to form heavier nuclei, releasing energy that powers stars and can provide a safe, sustainable, and clean source of baseload electricity. This process requires high temperatures and plasma, an ionized state of matter rare on Earth but common in the universe. The quest for fusion energy is closely associated with plasma physics and requires large-scale collaborative efforts.

Summary: According to the kinetic studies, the magnesiothermic reduction reaction (MRR) of silica for producing porous silicon (pSi) microparticles shows better precursor conversion and pSi yield under dynamic conditions compared to static conditions. The pSi microparticles, which are mesoporous and composed of interconnected primary silicon nanoparticles, exhibit significantly enhanced cycling stability when used as anode materials in lithium-based batteries. Therefore, the dynamic MRR (D-MRR) is a highly efficient and scalable production process for pSi microparticles for advanced lithium-based batteries.
