Summary: Chemical condensation of silicate layers has been suggested as an alternative to thermal condensation, but with limited success. The formation of MCM-22 zeolite from a mild hydrothermal precursor is a significant example of 2D-3D aluminosilicate condensation. Silanols from opposing layers are condensed through acid-driven dehydration, confirmed by XRD and NMR spectroscopy, indicating interlayer template extraction and dealumination. Gentler acid treatments promote template extraction and interlayer distance shrinkage, but lack significant silanol condensation. Template extraction is further enhanced by organic degradation in the presence of a Cu2+ catalyst.

Summary: Hierarchical S-doped In2O3 networks were synthesized with graphene oxide as a template and annealed. The effects of graphene oxide and annealing temperature on the morphology and phase of the samples were investigated. The hierarchical S-doped In2O3 networks consisted of nanosheets and microspheres assembled with nanowires and nanoparticles. The annealed hierarchical S-doped In2O3 networks at 500 degrees C showed the highest response (Ra/Rg) of 74.4 towards 50 ppm ethanol at 180 degrees C, which was approximately 2 times higher than that of S-doped In2O3 micro pompons prepared without graphene oxide. Moreover, the hierarchical In2O3 networks exhibited excellent selectivity and good stability to ethanol, which may be attributed to their unique hierarchical networks, high specific surface area (295.23 m2/g), and sulfur doping.

Summary: This study prepared complexes of alginate microgels (AMs) and hexadecyltrimethylammonium bromide (CTAB), which effectively stabilized oil-water emulsions. It was found that different concentrations of CTAB significantly improved the emulsifying capacity of AMs and enhanced the stability of the emulsions against centrifugation, pH changes, and NaCl concentration. The interfacial adsorption and morphology observation indicated that CTAB complexing contributed to the improved interfacial activities of the CAMs and the formation of an interfacial layer on the oil droplets' surface.

Summary: A scalable, spontaneous confined nanoemulsification strategy is proposed for the synthesis of uniform sub-10 nm polymeric nanoparticles. By introducing a high-concentration interfacial reaction, overpopulated surfactants insoluble at the droplet surface are formed as barriers, resulting in highly accumulated surfactants inside the droplet. These surfactants exhibit significantly changed packing geometry, solubility, and interfacial activity, leading to the creation of sub-10 nm nanoemulsions via self-burst nanoemulsification. Using the nanodroplets as templates, uniform sub-10 nm polymeric nanoparticles as small as 3.5 nm, made from biocompatible polymers and capable of efficient drug encapsulation, are demonstrated. This work opens up new opportunities for the creation of sub-10 nm nanoemulsions and advanced ultrasmall functional nanoparticles.

Summary: DNA origami molds enable controlled growth of metallic nanoparticles, but it is currently limited to gold and silver. This study demonstrates the fabrication of linear palladium nanostructures with controlled lengths and patterns. By developing a synthesis procedure of palladium nanoparticles using BSPP as a reductant and stabilizer, an efficient functionalization protocol with single-stranded DNA is established. Attaching functionalized particles to complementary DNA strands inside DNA molds allows specific seeded palladium deposition, resulting in rod-like palladium nanoparticles with grainy morphology.

Summary: In this paper, a facile method for fabricating β-Ga2O3 nanotubes using GaSb nanowires as sacrificial templates is reported. The length, diameter, and thickness of the nanotubes can be customized by using different GaSb nanowires and heating parameters. It is found that the Kirkendall effect and the sublimation process play critical roles in the transformation dynamics of the β-Ga2O3 nanotubes. The obtained β-Ga2O3 nanotubes exhibit promising photoelectric properties with high photoresponsivity and detectivity.

The results show that the growth behavior of sapphire along the c-axis is more complex compared to that along the a- and m-axes, involving solid-liquid and solid-solid transformations. Moreover, an abrupt change in the interfacial structure inhibits the transformation of liquid Al2O3 into α-Al2O3 along the c-axis.

Summary: Investigating the liquid structure of yttrium aluminum garnet (YAG) at high temperatures is significant for various fields, and molecular dynamic simulations were used to study the structure of YAG within a certain temperature range and to grow a YAG single crystal. The coordination number and bond length between cations and anions changed after melting, which can be explained by Pauling's third rule. In the liquid YAG, the coordination number decreased and the main structural units were AlO4 and YO7, which provided insight into phase selection and enabled rapid growth of YAG using the Czochralski method.
