Summary: In this study, lead-free BZT35 ferroelectric thin films were prepared by RF magnetron sputtering, and the effects of argon-to-oxygen ratios on their properties were investigated. The results showed that reducing the Ar/O2 ratio effectively suppressed oxygen vacancies and improved the dielectric properties and leakage resistance of the films. The BZT35 film prepared under Ar/O2 = 40:10 exhibited excellent energy storage performance and frequency stability.

Summary: Optical erbium oxide (Er2O3) films were prepared by RF magnetron sputtering to enhance the infrared transmittance of CVD diamond. The study analyzed the microstructure, composition, and optical properties of Er2O3 anti-reflection films with different oxygen/argon ratios. It was found that the surface roughness and crystalline structure of Er2O3 films decreased with an increase in the oxygen/argon ratio. The chemical composition of the films underwent a transformation, and defect behavior was observed at high oxygen/argon ratios. The highest transmittance was achieved at an oxygen/argon ratio of 1:35. A low oxygen/argon ratio was found to promote the growth and infrared transmittance of Er2O3 films.

Summary: The study showed that Nb/B4C/Si/B4C multilayers maintain good interface structures and minimal additional crystallization after annealing, while the interface structures of Nb/Si multilayers rapidly degrade and new compounds form at high temperatures. The introduction of B4C barrier layers significantly improves the thermal stability of Nb/Si multilayers.

Summary: The effect of the interface layer on energy release in nanoenergetic composite films is important. Experimental and simulation studies show that increasing the modulation period significantly increases the total heat release and the decrease in the interface layer promotes the reaction rate. Additionally, the number of interfacial layers has a significant influence on the Helmholtz free energy of the nanoenergetic composite films.

Summary: This paper proposes an environment-protecting method to fabricate a superhydrophobic nano-Al/NiO energetic film with uniformly distributed structures and high purity, using an improved electrophoretic assembly and stearic acid modification. The nano-Al/NiO energetic film exhibits superior anti-wettability and self-cleaning ability, and retains stable exothermic performance even after 10 immersion cycles, making it a promising candidate for practical applications. This design provides a novel strategy for enhancing the safety, flexibility, and adaptability of functional energetic surfaces in real industrial applications.

Summary: The direct molecular simulation (DMS) method is used to obtain shear viscosity data for non-reacting air and its components. Shear viscosity is estimated at several temperatures by fitting the DMS velocity profiles using the analytic solution of the Navier-Stokes equations. The simulations rely on ab initio potential energy surfaces (PESs) to describe atomic-level interactions and show good agreement with experimental data for molecular nitrogen, oxygen, and air.

Summary: In this article, a robust experimental model investigating strong metal-support interactions (SMSI) and their impact on electrocatalytic reactions is reported. The beneficial interactions between Ni0.9O thin film supports and PtNPs in the CO electrooxidation reaction are described. The results show negative shifts of the CO electrooxidation peak potential when Ni0.9O thin films are in contact with Pt55 NPs and Pt140 NPs, and the oxygen evolution reaction (OER) is suppressed only when PtNPs are in contact with Ni0.9O thin films. Density functional theory (DFT) calculations attribute the CO electrooxidation enhancement and OER suppression to changes in binding energies at the NiO(111)/Pt55 NP interface.

Summary: The study investigated the mechanical and tribological performance of WC/a-C nano-multilayers with different modulation ratios, and found that the best overall properties were achieved at a modulation ratio of 1:1.2. The enhanced tribological properties were attributed to the friction-induced formation of a WO3-rich transfer film under an appropriate WC individual layer thickness, which helped in constructing an intrinsically weak-interacting sliding interface. Additionally, graphitized carbon played a crucial role in the formation of the WO3-rich transfer film.

Summary: The influence of size and solid/liquid interface on the thermal conductivities of nanoscale liquid argon films with different forms was studied using the molecular dynamics method. The results showed that the anisotropy of thermal conductivity is closely related to the film's configuration and weakens as the film thickness increases. The analysis of the densities, potential energy distributions, and vibrational densities of state of argon atoms provided insight into the interface effect on the anisotropic thermal conductivity of nanoscale liquid argon films.

Summary: In the Big Data era, robust and stable crossbar-array memory cells are required for neuromorphic computing. However, elemental segregation in the switch unit and memory unit hinders compositional and structural stability. Tellurium (Te) has been discovered as a peculiar material without segregation for switching, and its memory function has been experimentally confirmed. The piezoelectric Te with spontaneous polarization shows great promise for constructing robust and high-density logic-in-memory chips in neuromorphic computing.

Summary: The importance of modulations in quantum materials, such as topological materials, magnetic materials, and superconductors, has reached an unprecedented level due to the delicate conditions required to bring out exotic phenomena. State-of-the-art modulation techniques, including electric-double-layer transistor, piezoelectric-based strain apparatus, angle twisting, and nanofabrication, have been employed in superconductors to increase tuning capability and dimensionality. This review contextualizes these techniques together with established modulation methods like elemental substitution, annealing, and polarization-induced gating, categorizing them into stoichiometric manipulation, electrostatic gating, mechanical modulation, and geometrical design based on their mechanisms. Recent advances and applications in newly discovered superconductors are highlighted, aiming to provide a systematic approach for modulations in emergent superconductors and stimulate further investigations.

Summary: Surface-enhanced Raman scattering (SERS) is a highly sensitive analytical technique for identifying chemical components and molecular structures, but faces challenges in absolute quantification. Coupling enhancement strategies, such as electromagnetic and chemical methods, offer key advantages over uncoupled SERS devices, improving sensitivity, reproducibility, and stability. Future development of coupling-enhanced SERS devices requires addressing remaining bottlenecks and implementing effective strategies.
