Summary: This paper introduces a well-ordered highly-crystalline g-C3N4 nanoarray with a conjugated electron donor-acceptor structure (PDI/CNA) to improve H2O2 production efficiency. Experimental and DFT investigations show that eliminating deep defect trapping sites can enhance charge utilization and reduce the Gibbs free energy of the rate-determining step. The optimized PDI/CNA demonstrates superior H2O2 production rate and high apparent quantum yield.

Summary: In this paper, ordered calcium silicate hydrate (C-S-H) plates were fabricated using Layer-by-Layer (LBL) method and H-cell penetration (HCP) method through cation exchange membrane templating. This new method changed the randomly packing structure of traditional C-S-H and synthesized a high-orderly C-S-H platelets with denser structure. Molecular dynamics simulations and AFM indentation experiments demonstrated the strong adsorption and nucleation sites contributed by sulfonic acid groups on the cation exchange membrane and the significantly higher mechanical properties of this new type C-S-H. The addition of PVA and the regulation of reaction time further improved its mechanical properties. This new C-S-H may pave the way to the preparation of high-performance concrete in the future.

Summary: Despite its well-defined helical structure, PDMS remains an amorphous fluid even at extremely high molecular weights due to the high flexibility of the siloxane backbone and lack of intermolecular interactions. PDMS is incompatible with most organic or inorganic components, leading to phase separation in copolymers. Self-assembly at the micro- or nanometric scale is common in mixed structures involving PDMS.

Summary: The study demonstrates hierarchical morphology control in Layer-by-Layer (LBL) organic photovoltaic (OPV) cells using a dual functional solid additive. By individually or simultaneously introducing the solid additive to the donor or acceptor layer, preferable vertical component distribution and enhanced molecular crystallinity were achieved, leading to high power conversion efficiencies of 16.4% and 17.4% in binary and quaternary LBL devices. This approach offers an alternative method to manipulate the morphology of LBL OPV cells for improved efficiency and stability.

Summary: This paper investigates the effect of cellulose nanocrystals (CNCs) on the microstructural and mechanical properties of calcium silicate hydrates (C-S-H). The results show that CNCs effectively mitigate agglomeration of C-S-H, resulting in highly ordered, layered, and dense microstructures in C-S-H/CNC nanocomposites. The strong interactions between C-S-H and CNCs contribute to the high strength and flexibility of the nanocomposites.

Summary: miR-210 has a context-dependent regulation on the inflammatory response, with overexpression associated with improved angiogenesis and tissue repair. Infiltrating cells with mismatched miR-210 levels lead to a pro-fibrotic phenotype, impairing tissue repair, causing fibrosis, and dysfunctional angiogenesis.

Summary: This study investigated the interaction of PD-L1 with its antibody and PD-1 using atomic force microscopy-based single molecule force spectroscopy for the first time. The PD-L1/anti-PD-L1 antibody complex was found to be easier to dissociate than PD-L1/PD-1, and PD-L1 was randomly distributed on T24 cells surface. The expression of PD-L1 on T24 cells increased after INF-g treatment.

Summary: The principles of algebraic image reconstruction are applied to THz computed tomography to address the issue of refraction within the sample. A highly accurate and robust image reconstruction algorithm is presented based on the physics of geometric optics and the prior knowledge of the nominal sample geometry. The validity of the geometric forward model is verified through numerical simulation, and the developed method is experimentally tested with a fast THz-CT system. Automated evaluations demonstrate the high accuracy of the reconstructed sample cross sections.

Summary: Redox imbalance of endothelial cells plays a crucial role in cardiovascular diseases. The study found that circular RNA circANKRD12 was significantly upregulated in endothelial cells exposed to oxidative stress, and its silencing inhibited endothelial cell proliferation and capillary-like structure formation. Furthermore, bioinformatics analysis revealed the enrichment of the p53 and Foxo signaling pathways in the circANKRD12-miRNA-mRNA regulatory network in H2O2-treated endothelial cells.

Summary: This study investigates molecular recognition in a synthetic confined nanopore with controllable pore dimension and molecular DNA receptors at different depth positions. The results show that the association rates are slower and the dissociation rates are faster for receptors positioned deeper inside the pore lumen. This phenomenon can be explained by the steric constraints on molecular interactions in confinement.

Summary: The study compared influenza virus receptor specificity with virus binding to live cells using glycan arrays and single-virus force spectroscopy. The findings revealed that the receptor binding preference of the virus does not necessarily reflect its specificity to cells. Single-virus force spectroscopy was proposed as a tool to understand the cell binding preference of influenza A viruses.

Summary: This study aims to explore the role of noncoding RNAs in cardiovascular diseases. The research found that circular RNAs can interact with microRNAs, regulating the expression of cardiovascular disease-related signaling pathways. Specifically, the study found that circBPTF is upregulated under hypoxia conditions and can regulate the function of endothelial cells by targeting miRNA targets such as HDAC9 and LRRC17.
