Summary: This work presents the synthesis and characterization of bulk Y2Ti2O7-aluminum nano-composites using high energy ball-milling followed by spark plasma sintering. Stable Y2Ti2O7 nanoparticles were prepared by mechanical alloying and calcination, and then dispersed in an aluminum matrix for reinforcement. The introduction of 1wt% Y2Ti2O7 significantly enhanced the compressive yield strength of the material.

Summary: In this work, composite thin films consisting of titanium dioxide and noble metal nanoparticles (silver, gold, and bimetallic silver/gold alloys) were synthesized using RF magnetron sputtering. The resulting thin films were characterized using various techniques, including TEM, SEM, XRD analysis, and Raman spectroscopy. The study showed that annealing in an argon atmosphere induced crystallization in the initially amorphous TiO2 matrix. The composite films exhibited two light absorption regions, one associated with localized surface plasmon resonance (LSPR) phenomena and the other due to the energy band gap. The composition of the metal nanoparticles could be adjusted to tune these parameters in the composite films.

Summary: This study demonstrates the comparison of two different semiconductor materials, TiO2 and melem/g-C3N4 composites, modified with Ag nanoparticles as photocatalysts for degradation of acid orange 7 (AO7) dye. A new synthesis route for Ag NPs was proposed, and the best photocatalytic performances were achieved for TiO2 and melem/g-C3N4 materials modified with a very low Ag content. The results suggest the potential of these materials for the degradation of organic contaminants in wastewater treatment.

Summary: A polymer nanoparticle network was designed using single-chain nanoparticles as cross-links. Experimental and theoretical studies demonstrated that this network exhibited smaller mesh size, faster terminal relaxation time, and reduced fluctuation among cross-links, resulting in increased shear storage modulus and enhanced tensile stress. Importantly, the reversible single-chain collapse of the nanoparticles under thermal stimulation enabled the network to undergo coherent changes between two topological states, demonstrating reversible transformations between soft and stiff states.

Summary: This article presents a directly 3-D printed soft monolithic robotic finger with embedded soft pneumatic sensing chambers (PSC) as position and touch sensors. The soft hinges with embedded PSCs have several advantages, such as fast response to very small changes in their internal volume, linearity, negligible hysteresis, repeatability, reliability, long lifetime, and low power consumption. Real-time position and pressure/force control of the soft robotic finger were achieved using feedback signals from the soft hinges and the touch PSC embedded in the tip of the finger.

Summary: This study focuses on tailoring cinnamon oil emulsion-based gelatin edible films for encapsulating, protecting, and releasing bioactive compounds in food packaging. The results show that the cinnamon oil film significantly improves the mechanical, water barrier, antioxidant, and thermal properties. The film also extends the shelf-life and reduces weight loss of wax apples. Additionally, encapsulation of bioactive compounds in the film is influenced by the ratio of oil to surfactant mixture in the emulsion.
