Summary: The polymeric origami structure demonstrated in this study follows predetermined deformed and non-deformed patterns at specific temperatures without molding, utilizing a heterogeneous network topology constructed via light-induced programming. This allows for varied deformability within a single polymer and guided origami deployment in response to external forces. Additionally, the self-locking origami can fix its geometry in specific states without pressurization, enabling the development of shape-reconfigurable structures that undergo geometry changes on demand.

Summary: This study demonstrates the transformation of one type of superhydrophobic surfaces to another by changing surface topography alone, resulting in solid surfaces with tunable properties. The different surfaces, featuring gecko, petal, and lotus effects, were achieved by adjusting the roughness factor and length scale of roughness, while maintaining the same surface chemistry. The study investigates the behavior of water droplets on these surfaces, revealing similarities in spreading but differences in sliding, receding, jetting, and rebounding due to the variations in adhesive properties. The research also provides explanations for the different behaviors based on existing equations for surfaces with petal and lotus effects, while the surface with gecko effect is attributed to negative pressure generated by sealed air within its structure.

Summary: Ascorbic acid (vitamin C) is considered as a viable alternative fuel for alkaline direct liquid fuel cells. Palladium nanoparticles (Pd NPs) were incorporated into reduced graphene oxide (rGO) and multiwall carbon nanotube (MWCNT) hybrid nanocomposite (Pd/rGO/MWCNT) through a chemical reduction method for electrooxidation of ascorbic acid (AA) in the alkaline condition. The Pd/rGO/MWCNT modified glassy carbon electrode (Pd/rGO/MWCNT/GCE) exhibited the highest current density of 5.18 mA cm(-2) for AA electrooxidation, much higher than a bare glassy carbon electrode (0.6 mA cm(-2)). Pd/rGO/MWCNT/GCE also demonstrated excellent stability for AA oxidation in the alkaline condition.

Summary: In this study, a deep learning-based inverse design framework was developed for disordered architected cellular materials (Voronoi lattices). A three-dimensional conditional generative adversarial network (3D-CGAN) was trained using a dataset of voxelized Voronoi lattices and their corresponding relative densities and Young's moduli. The well-trained 3D-CGAN generated multiple distinct Voronoi lattices with the target relative density and Young's modulus through variational sampling. The mechanical properties of the generated Voronoi lattices were validated through compression tests and finite element simulations, demonstrating the potential use of the inverse design framework in bone implants.

Summary: In recent years, there has been significant research on functional materials inspired by living organisms, specifically adhesive materials mimicking the adhesive proteins of mussels. These mussel-inspired materials exhibit superior adhesiveness due to non-covalent interactions of their polyphenolic moieties. Factors such as molecular weight, cross-linking density, and composition ratio affect the adhesiveness, but the importance of position and distribution of the adhesive moiety is often underestimated. This study investigates the effects of monomer position and distribution on adhesion and dispersion behavior of mussel-inspired polymers, providing insight into the design of bio-inspired adhesive materials for a sustainable circular economy.

Summary: High-density crosslinked polymer membranes with a thickness of several tens of nanometers were prepared using chemical vapor deposition (CVD) of propylamine (PA). The membranes had a composition of C3.0H4.7N0.8O0.4 and contained various functional groups. The pore sizes of the membranes were found to be 0.3-0.7 nm, and their porosity was approximately 10%. The study demonstrated the ability to tune the thickness, pore size, porosity, and density of these hydrophilic crosslinked membranes by adjusting the CVD parameters.

Summary: This study investigated the performance of an iridium-oxide-layer-deposited platinum surface as a catalyst for ethanol oxidation reaction in an alkaline medium. Results showed that while the pure platinum catalyst exhibited higher activity towards EtOR compared to IrOx-Pt, the latter had better CO tolerance and stability. The cyclic voltammetry analysis indicated that the electrode reaction was limited by mass transfer.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
