Summary: In this study, a comprehensive approach involving diffusion couples, nanoindentation, EPMA, and CALPHAD techniques was used to construct a Young's modulus database for Ti alloys with various compositions. By experimentally preparing quaternary diffusion couples and using EPMA and nanoindentation probes, the composition-dependent mechanical properties of Ti-based alloys were obtained. Ultimately, a CALPHAD-type database was established for the bcc Ti-Nb-Zr-Mo system, providing accurate Young's moduli for Ti alloys with wide compositions.

Summary: Ceramic samples of polycomponent solid solution (Y0.96Eu0.01Sm0.01Tb0.01Er0.01)Nb0.7Ta0.3O4 were prepared by sol-gel synthesis using rare earth elements REE nitrate solutions and coprecipitated hydroxides of niobium and tantalum. The crystal lattice of the initial powders was investigated, and the microstructure of the ceramics samples was studied based on different temperature regimes during preparation. The strength characteristics (Young's modulus) and critical stress intensity factor of the ceramics were estimated. The cathode- and photoluminescent properties of the ceramic solid solutions (Y0.96Eu0.01Sm0.01Tb0.01Er0.01)Nb0.7Ta0.3O4 were also studied.

Summary: Flexible transparent electrodes have been in high demand for touch panels, solar cells, and wearable electronics. Among the top choices is the silver nanowire (AgNW) flexible transparent electrode (FTE) due to its excellent light transmittance, flexibility, and highest conductivity among all metals. However, the large contact resistance has limited the conductivity of AgNWs network. By nanojoining AgNWs with graphene oxide (GO), the conductivity of the AgNWs network can be significantly improved, resulting in a low sheet resistance and high light transmittance for the AgNW-GO FTE.

Summary: The synergistic interaction between different components in heteronanocrystals leads to interfacial phenomena and novel functionalities. However, there is still a lack of effective technologies for designing and fabricating heteronanocrystals with specific materials. Copper tarnish has been found to form rich heterostructures at room temperature and atmospheric pressure. Inspired by the redox process of copper, a simple strategy has been developed to achieve heteronanocrystals containing elements from group 3-11 and group 14-16. The interface redox-induced method is self-regulating under ambient conditions and can be applied to metals, semiconductors, and dielectric materials.

By exploring the co-assembly of L-His with different aromatic amino acids, including Phe, Tyr, and Trp, we expanded the structural space of amino acid nanomaterials. The best seamless co-assembly was observed between L-His and L-Phe, resulting in the formation of single crystals.

Summary: Researchers have constructed a metal-free 2D p-n junction heterophotocatalyst composed of violet phosphorene and two-dimensional carbon nitride sheets using a simple electrostatic self-assembly method. The study demonstrates that the built-in electric field of the p-n junction enhances the separation of photogenerated carrier pairs at the heterojunction interface, leading to improved visible-light photocatalytic activity. The CNs/VP heterojunction exhibits significantly enhanced rates of visible-light photocatalytic hydrogen and CO production compared to CNs.

Nanomaterials, especially self-assembling peptides, show great potential in drug delivery by promoting drug release and stability while reducing side effects. This review highlights the importance of metal coordination, structure stabilization, cyclization, and minimalism in the design of peptide self-assembled nanocarriers for cancer drug delivery. Future perspectives suggest that incorporating these materials into single or multicomponent systems could lead to novel classes of cancer drug delivery systems.

Summary: In recent years, computational methods, particularly dispersion-corrected density functional theory (DFT), have been used to predict and design the mechanical response of molecular crystals. The results show that the supramolecular packing, such as extended H-bond or ir-ir networks, plays a crucial role in determining the mechanical behavior of the crystals. This has important implications for drug development.

Summary: This study demonstrates the use of liquid-based atomic force microscope and graphene liquid-cell-based scanning transmission electron microscope to observe chemically induced protein unfolding. The results show that fully folded ferritin proteins transform into rings after urea treatment but not after guanidinium treatment. Nanorings are a specific signature of denaturation of holo-ferritins after exposure to sufficiently high urea concentrations. The study also suggests that electrostatic destabilization triggers denaturation of ferritin as urea makes direct contact with the protein and disrupts the water H-bonding network in the ferritin solvation shell.
