Summary: The Cold Sintering Process was used to promote in situ reactive sintering of hydroxide precursors Al(OH)3, xH2O. The result was dense translucent pellets containing a mix of amorphous and crystalline phases. Further heat treatment induced the transformation of boehmite into gamma-Al2O3, demonstrating the possibility of producing optically translucent ceramics with low temperature stability.

Summary: This study reports a new strategy for the in situ fabrication of heterogeneous nanomaterials based on metal-organic frameworks (MOFs) and optically active nanomaterials through hierarchical and dynamic assembly. The formation mechanism of the core-satellite structured UiO-66-NH2@UCNRs was thoroughly investigated. Based on the optical and porous features of the heterogeneous nanomaterials, an enhanced multimodal synergistic anticancer platform was established and confirmed through cellular experiments.

Summary: Modified theta-Al2O3@ polyethylene glycol (PEG) technology was used to prepare alpha-Al2O3 green compacts composed of <100-nm alpha-Al2O3 crystallites using theta-Al2O3 as the starting material. The preparation process consisted of two steps, involving the removal of PEG to separate alumina crystallites in theta-Al2O3 compacts and the transformation of theta-Al2O3 into alpha-Al2O3. The resulting compact exhibited a phase purity of >85% alpha-Al2O3, with crystallite sizes ranging from 50 to 100 nm, and a compact density exceeding 60% of the theoretical value.

Summary: In this study, MnOOH nanohydrangeas and MnOOH nanorods were prepared by a hydrothermal reduction route and used as active anodes for Li-ion batteries. The comparison of their lithium ion energy storage performances showed that gamma-MnOOH nanorods exhibit enhanced cycle and rate capacity, making them a promising candidate for lithium ion battery applications.

Summary: The characteristics of bio-oil derived from soybean meal were improved through hydrodeoxygenation using monometallic and bimetallic catalysts. The oxygen content was reduced and the heating value of the bio-oil increased. The Ni/gamma-Al2O3 catalyst was found to be more effective in reducing oxygen content and increasing the heating value.

Summary: Hydrogen, with its efficient energy storage and carbon-free features, is considered a promising future energy source. The energy input required for hydrogen production is a crucial factor, and current water electrolysis methods are hindered by the high overpotential of the oxygen evolution reaction (OER). The formaldehyde oxidation reaction (FOR) provides a thermodynamically favorable alternative, and our designed catalyst efficiently produces hydrogen at an ultra-low potential and maintains long-term stability, achieving nearly 100% Faraday efficiency (FE) when combined with the cathodic hydrogen evolution reaction (HER).

Summary: This study demonstrates a novel chiral organization of multi-materials through co-assembly of semiconducting quantum nanorods into chiral nematic polysaccharide nanocrystals, enabling active manipulation of chiro-optical light emission properties in elastomeric materials. The resulting bio-inorganic elastomeric materials exhibit vivid iridescence and emission with strong optical activity, providing possibilities for futuristic applications in chiral lasing, biosensing, optical gauges, and holographic display. Large-strain reversible mechanical deformation of physically crosslinked elastomers allows fully reversible alternation of helical structural configuration and corresponding linearly and circularly polarized photoluminescence.

Summary: In this study, biopolymer chitosan is used as a template to synthesize and shape mesoporous gamma-Al2O3 macrospheres. The resulting porous granules exhibit a high surface area, pore volume, and pore diameter. A full factorial design based on a mathematical model is employed to investigate the effects of acid concentration, chitosan amount, ammonia concentration, and aging time on the responses. The model shows a satisfactory agreement with experimental values, and various characterization techniques are used to analyze the structure of the prepared gamma-alumina sample.

Summary: In this study, mesoporous gamma-Al(2)O(3)NPs were created using a simple method based on non-ionic surfactant polysorbates-80, and thin-film nanofiltration membranes were fabricated using these nanoparticles. The mesoporous gamma-Al(2)O(3)NPs were found to enhance the hydrophilicity and surface negativity of the membranes, leading to increased water flux and improved removal of polyvalent cations.

Summary: This study proposes a new strategy to enhance the mechanical properties of hydrogels through the modulation of ionic interactions. The strategy involves the formation of crystalline micro-nanoparticles (CMNPs) through confinement assembly, and the introduction of these CMNPs into polyacrylamide hydrogels. The composite hydrogels showed significantly improved modulus, fracture stress, and toughness without affecting their tensile properties. Furthermore, a strain sensor for monitoring human motion was designed and demonstrated its potential application in wearable flexible electronics.
