Summary: Eu3+-(5% mol)-doped Lu2SiO5 optical quality films were prepared using the sol-gel method and dip-coating technique. The incorporation of Eu3+ ions did not affect the monoclinic crystalline phase of Lu2SiO5. Films without surfactant exhibited a uniform and low rugosity morphology, while films with surfactant showed porous hills and valleys with uneven roughness. The photoluminescence spectrum of Eu3+:Lu2SiO5 films exhibited 2 broad emission peaks. The presence of Glymo promoted the formation of residual Lu2Si2O7 compounds with higher lifetime values.

Summary: Titanium oxide (TiO2) thin films were prepared via the sol-gel spin-coating technique. The effects of indium (In), hafnium (Hf), and In&Hf doping on the electrochemical and structural properties of TiO2 were investigated. The structural properties were characterized using TG/DTA, XRD, and AFM, while the optical properties were studied using UV-Vis spectroscopy. It was found that TiO2 exhibited good electrochemical properties and the band gap energy increased with In&Hf doping.

Summary: Mesoporous thin films are widely used for their high surface area and efficient mass and charge transport properties. A two-step calcination process can reduce film contraction and enhance structural control, resulting in mesoporous films with higher porosity and larger pores. These films exhibit favorable characteristics for mass transport of large molecules.

Summary: Undoped ZnO and Mg-doped ZnO thin films were synthesized by sol-gel dip-coating technique. The study showed that Mg doping increased the porosity of the films, decreased their crystallinity, and led to the formation of localized energy states. The enhanced photocatalytic efficiency of Mg-doped ZnO thin films was attributed to charge trapping by localized states and an increase in surface area due to porosity induced by Mg doping.

Summary: This study presents a new approach to achieve superlubricity for DLC films by introducing metal nanoparticles on the films, which does not rely on the film preparation parameters. The metal nanoparticles control the structures of wear products and enable the formation of graphene-coated particles at the interface, leading to metal-carbon interfacial superlubricity with significant changes at the frictional interface.

Summary: This study addresses the challenge of scalable pressureless sintering of nanocrystalline alumina ceramics using ultrafine alpha-Al2O3 nanopowders and a two-step sintering technique. The results show that the exceptional sinterability of these nanopowders can be attributed to their small size, large surface area, and good dispersity, rather than a new sintering mechanism. The importance of fast firing and non-equilibrium nature for low-temperature sintering of such nanopowders is highlighted.

Summary: This study reports a facile way to achieve robust macroscale superlubricity in a vacuum environment by forming graphene/transition-metal dichalcogenide (TMDC) heterostructures on wear-induced rough surfaces. The sandwich structures readily transform into graphene/TMDC heterostructures during running-in stage, and assemble into multipoint flake-like tribofilms to achieve macroscale superlubricity.

Summary: The study introduces a novel method to achieve high load-bearing and ambient robust superlubricity by utilizing the deformation of FL-C:H substrate to disperse high contact pressure and maintain structural integrity of 2D materials. By preparing graphene with few defects using BSEG technique, environmental chemical interaction is weakened, leading to superlubricity under both vacuum and ambient conditions at high load. This approach bridges the gap between structural superlubricity and practical applications, potentially reducing energy dissipation significantly.
