Summary: Solid supported or ligand capped gold nanomaterials (AuNMs) have emerged as versatile and recyclable heterogeneous catalysts for a broad variety of conversions in the ongoing catalytic 'gold rush'. AuNMs, existing at the border of homogeneous and heterogeneous catalysis, have the potential to merge high catalytic activity with significant substrate selectivity. This work summarizes well-defined catalytically active NHC capped AuNMs, including spherical nanoparticles and atom-precise nanoclusters, as well as the important NHC design choices towards activity and (stereo-)selectivity enhancements.

Summary: Organ dysfunction is a major cause of morbidity and mortality, with transplantation being a key cure but facing challenges due to a lack of donor organs. Tissue engineering using biomaterial scaffolds shows promise in promoting cell attachment, proliferation, and differentiation for tissue regeneration in bone, nerve, and cardiovascular applications. The development of scalable scaffolds using polyhydroxyalkanoate fibers presents an exciting opportunity for both hard and soft tissue regeneration.

Summary: Surfactant crystals can stabilize liquid foams by adsorbing onto bubble surfaces, preventing coarsening and coalescence. Controlling the amount of crystals can lead to ultra-stable foams, while the melting of crystals allows for the design of thermoresponsive foams. The field is expected to grow in the coming years, contributing to the engineering of new soft materials for various applications.

Summary: This study prepared walnut protein isolate nanoparticles (nano-WalPI) using pH-cycling and ultrasound, investigated the impact of different nano-WalPI concentrations and oil volume fractions on the stability of Pickering emulsion, and improved the utilization of walnut residue. The nano-WalPI had uniform size (average size of 108 nm) and good emulsification properties, forming stable O/W-type Pickering emulsion. The best stability of Pickering emulsions was achieved with 2.0% nano-WalPI concentration and 60% oil volume fraction, forming an elastic weak gel network structure with good thermal and storage stability.

Summary: Thin-shell models and rigorous thick-shell theory for fluid-loaded spherical shells exhibit inconsistencies in studying the sound-structure interaction. In this paper, the linearized equations of motion for fluid-loaded, thin, spherical shells are derived from first principles, and the significance of differences in fluid-loading terms from previous models is analyzed. Analytic solutions are obtained for the scattering of sound waves and resonant vibrations of a fluid-filled, prestressed spherical shell, and the effects of shell material properties and prestress on low-frequency underwater sound radiation are investigated.

Summary: A controlled pressurized microbubble generation system has been developed, which can produce numerous microbubbles under certain pressure using multi-channel ceramic membranes in a surfactant-free system. The average diameter and size distribution of the microbubbles are significantly influenced by various factors. A mathematical model is established to predict the optimal membrane parameters and bubble size under different operating conditions. This work contributes to the understanding and development of high-performance microbubble generation.

Summary: The research found that biogenic gold nanoparticles can inhibit protein amyloidogenesis, which is linked to chronic diseases such as Alzheimer's and Parkinson's disease. The synthesized nanoparticles, stabilized with quercetin-functionalized tara gum, demonstrated strong anti-aggregation and fibrillation effects against amyloidogenic proteins. They also showed potential for countering protein aggregation and associated disease conditions.

Summary: Research shows that the thiolated analog of a protein has a greater affinity for gold nanoparticles (AuNPs) and is able to form a robust hard corona, maintaining structure and function, compared to the unmodified protein which denatures with prolonged exposure to AuNPs resulting in loss of enzymatic function.

Summary: Understanding and controlling deposit patterns is crucial for various applications. This study investigates the effect of polymer and surfactant on the drying dynamics and structure of nanoparticles in dried deposits. The results show that the addition of surfactant can modify the evaporation kinetics and deposit patterns of the colloidal droplets, demonstrating the potential for systematic control of droplet drying and deposition through the manipulation of internal flows.

Summary: A high NIR sensitivity and spectral selectivity photothermal detector was developed by modifying a photothermal layer of reduced graphene oxide-Au nanorods hybrid. The detector converts light energy into heat and measures resistance changes. The hybrid material exhibits remarkable photothermal conversion efficiency and dependence on spectral response, resulting in high sensitivity to illumination in the wavelength range from 700 to 1000 nm.
