Summary: Graphene aerogels with hierarchical porosity structures composed of nanopores in the plane of graphene oxide sheets and macropores in aerogel have shown high-performance microwave absorption capability. The efficient absorption bandwidth can reach 7.1 GHz and the minimum reflection loss is -36.4 dB. The hierarchical porosity, interfacial polarization, multiple reflections, and matched impedance contribute to the improved microwave absorption performance. Therefore, the design of high-performance radar absorption materials inspired by low filling content, low density, and special hierarchical porosity is feasible.

Summary: In this study, silica aerogels reinforced with sorbitol were prepared via sol-gel polymerization, improving the mechanical properties while maintaining the textural structure. Sorbitol with surface hydroxyl groups was covalently cross-linked with tetraethoxysilane (TEOS) or methyl trimethoxysilane (MTMS) precursor. Different properties were achieved by varying the mol% of the precursor. The results demonstrate the usefulness of using small organic molecules for cross-linking in obtaining aerogels with high surface area and improved mechanical properties.

Summary: The development of silica aerogels with controlled mechanical properties is essential for practical applications. Synthesis of native silica aerogels was achieved using the sol-gel method and the alkoxide precursor of silica (TMOS). This study investigated the influence of three synthesis parameters, namely TMOS concentration, catalyst concentration, and solvents (MeOH, EtOH, IPA), on the gel point, shrinkage, and mechanical properties of the aerogels. Structural studies revealed how these synthesis parameters affected the spatial network and elasticity of the aerogels. The analysis demonstrated that the catalyst concentration was the most significant parameter, as it led to a significant increase in Young's modulus (E) without affecting the bulk density (rho), possibly due to an increase in specific surface area and bond diameter between secondary particles in the aerogel.

Summary: The study introduces a new method for evaluating pore structures in carbon materials, using high-pressure CO2 adsorption isotherms to determine the pore size distribution in both micro- and mesopores. By utilizing Monte Carlo simulations and meso-canonical ensemble methods, capillary condensation transitions in mesopores were successfully predicted, demonstrating the feasibility of the technique in micro-mesoporous carbon materials.

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.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
