Summary: This article introduces a novel method for the manufacturing of ultra-lightweight aerogels with desired characteristics through the controllable liquid templating and interfacial complexation. The engineered liquid templates, formed by the assembly of nanoparticles and microspheres at liquid-liquid interfaces, result in hierarchical macroscopic aerogels with multiscale porosity, ultralow density, high compressibility, and elastic resilience. The controllable nature of this approach enables the tuning of the aerogels' properties for advanced applications and functions, pushing the boundaries of lightweight materials.

Summary: This study presents the successful construction of pure DNA aerogels and DNA-wrapped carbon nanotube (CNT) composite aerogels. These aerogels exhibit highly porous and randomly branched structures with low density. The pure DNA aerogel behaves like a simple capacitor, while the DNA-CNT aerogel demonstrates resistive switching behavior similar to a volatile memristor. These novel aerogels can potentially serve as a platform for developing biomimetic devices for various applications and pave the way for constructing aerogel-based material platforms from DNA-coated or wrapped functional entities.

Summary: A new type of transparent aerogels with biopolymer-polysiloxane double networks is introduced. The drawbacks of strong hydrophilicity and difficulty in achieving homogeneous nanoscale structures in biopolymer aerogels are overcome by incorporating a polysiloxane network. The resulting alginate-polymethylsilsesquioxane aerogel exhibits high optical transparency, water repellency, superinsulation properties, and improved flexibility, making it a promising material for various applications.

Summary: The global push toward decarbonization and electrification has led to a growing research effort to achieve higher device performance goals. Thick electrodes are being explored as a way to increase the fraction of active materials in electrochemical energy storage devices (EESDs), but overcoming ion-transport limitations is a challenge. Promising strategies, such as additive manufacturing techniques and the development of 3D-printable inks and resins, are being identified to address these limitations and improve the performance of EESDs.

Summary: This study prepared aerogels based on hyaluronic acid (HA) without chemical crosslinking and investigated the influence of solution pH, HA concentration, and nonsolvent type on the properties of the aerogels. The results showed a strong dependence of aerogel properties on solution pH, with the highest specific surface area and lowest density obtained at the isoelectric point of HA (pH 2.5). This work provides valuable insights into the development of neat HA aerogels for biomedical applications.

Summary: This study successfully fabricated PVDF/MXene hybrid aerogels with highly ordered MXene nanosheets and anisotropic porous structures. These aerogels exhibit different properties in different directions, and possess anisotropic compression performance, heat transfer, electrical conductivity, and EMI shielding. By increasing the MXene loadings, the electrical conductivity and EMI shielding performances of the hybrid aerogels were significantly improved. These aerogels also have sticky hydrophobicity and low water adhesion, making them suitable for self-cleaning.

Summary: Thin film polyethylene oxide, produced by the thermal evaporation technique, exhibits structural and property differences compared to bulk polyethylene oxide. The dielectric constant of polyethylene oxide thin film is 10 times greater than that of bulk polyethylene oxide. There is consistency among dielectric constants, activation energies, and free volume fractions for both thin film and bulk samples. Polyethylene oxide thin film is observed to be more brittle than bulk polyethylene oxide.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.

Summary: The relationship between the heterogeneous structure and structural relaxation in metallic glasses was explored by investigating the quasielastic and viscoelastic behavior of a Zr55Cu30Ni5Al10 metallic glass. Stress-annealing treatment was used to retain elastic strain energy, and a unique creep recovery phenomenon was observed during the reheating process. The Maxwell model was employed to qualitatively describe the mechanisms of elastic strain energy retention and release.
