Summary: This paper investigates the influence of oxygen bulk diffusion within FeVO4 oxygen carrier pellets on the chemical looping oxidative propane dehydrogenation (CL-ODH). The study finds that the main reactions of selective oxidation and over-oxidation are controlled by the oxygen bulk diffusion, and the propane conversion rate decreases while the C3H6 selectivity increases during the stage with stable surface oxygen concentration. Additionally, the reaction rates can be enhanced by increasing the propane partial pressure until the bulk transfer reaches its limit at higher propane partial pressure.

Summary: A three-dimensional model of osteocyte was established to investigate the mechanisms of mechano-transduction and amplification of primary cilium and osteocyte process in different gravity fields. The study found that there was significant stress concentration in the area where TES and the osteocyte process were physically connected, with fluid shear stress (FSS) two orders of magnitude higher than in other areas. The TES structure had a significant amplification effect on mechanical stimulation, making the osteocyte process the optimal mechanical receptor. In microgravity, the mechanical signal conduction ability of the osteocyte decreased significantly.

Summary: In this study, one-dimensional SAPO-11, SAPO-31, and SAPO-41 with different pore sizes were synthesized and used as supports for Pd catalysts. Molecular dynamics simulation revealed that the diffusion of reactants and intermediates in the micropore channels was strongly affected by the opening size of the channels. The Pd/SAPO-31 catalyst showed the highest activity and yield of iso-hexadecane in the hydroisomerization of n-hexadecane, attributed to improved diffusion and favorable metal-acid balance. Furthermore, it was found that the hydroisomerization over Pd/SAPO-31 occurred via the key lock mechanism, leading to a high proportion of multi-branched iso-hexadecane at high conversion of n-hexadecane. The Pd/SAPO-31 catalyst was proven to be an effective bifunctional catalyst for industrial biodiesel production.

Summary: CO can reactivate uptake of agomir in pathological conditions via RAB5-mediated endocytic pathway, and a responsive nanoparticle-crosslinked injectable hydrogel (CO-Ago gel) was designed to co-deliver CO and Ago to inhibit MMP overexpression. Compared to a typical matrix-enhanced gene therapy (Ago gel), CO-Ago gel significantly improved the uptake of Ago, achieving a several-fold enhancement of targeted gene expression under pathological conditions. The therapeutic effect of CO-Ago gel on MMP overexpression was assessed in rat models of myocardial ischemia reperfusion and diabetic skin wound healing, suggesting its potential in gene-based therapies and vaccines in vivo.

Summary: With the rise of drug-resistant bacteria, photothermal therapy (PTT) is a promising solution for treating infected diabetic skin ulcers. However, tissue damage caused by heat limits its clinical application. A CO-mediated PTT agent (CO@mPDA) was developed to inhibit bacterial growth and promote tissue regeneration. The CO-mediated PTT exhibited higher efficacy in inhibiting drug-resistant bacteria and lower heat resistance in mammalian tissues. It also upregulated tissue-protective proteins to reduce thermal injury. This approach offers a potential way to enhance PTT efficiency and minimize side effects when treating infected skin wounds.

Summary: This study reports the direct photosynthesis of hydrogen peroxide (H2O2) from seawater as a scalable and cost-effective solar fuel production method. The decoration of Au on Ni5P4 (Au@Ni5P4) was found to be an active and durable photocatalyst for non-sacrificial H2O2 synthesis from real seawater. Mechanism studies showed that the plasmonic Au decoration significantly suppressed charge-carrier recombination, and oxidation of halide ions in seawater assisted in H2O2 production.
