Summary: The paper focuses on the peeling of an elastic thin film from a rigid substrate with periodic surface undulations, considering contact between the detached film and the substrate. It reveals that roughening the surface can make the peel-off force independent of the peeling direction, and in the regime of large roughness, the peel-off force reaches its theoretical upper bound.

Summary: The critical adhesion value G(w,c) in capillary peeling is found to be proportional to the water-film interfacial energy, allowing for quantitative thermodynamic guidelines for designing thin film interfaces. This technique shows promise for thin film transfer and nanofabrication in various fields such as flexible photovoltaics, battery materials, biosensing, translational medicine, and stretchable bioelectronics.

Summary: The study fabricated thin-film composite (TFC) nanofiltration (NF) membranes with high rejection and high water flux by covering polyethylene (PE) membrane with polydopamine and polyethyleneimine (PDA/PEI), and then initiating interfacial polymerization (IP) with trimesoyl chloride (TMC) to form a dense and negatively charged polyamide-polyester selective layer. The membrane demonstrated efficient removal of anionic dyes at high water flux and excellent selectivity for dye/NaCl mixture solution.

Summary: Elemental antimony has been proposed as a promising material for phase change memories due to its improved performance compared to ternary chalcogenide alloys, with compositional simplification preventing reliability issues. The stability of amorphous phase in an ultrathin film of antimony is attributed to nanoconfinement. Molecular dynamics simulations reveal the microscopic origins of this effect.

Summary: Solution-processable transparent metal oxide thin-film transistors (TFTs) have great potential for large-scale optoelectronics, but their current performance is poor. In this research, a novel ultrathin crystalline indium-boron-oxide (In-B-O) channel layer was created to improve the performance of TFTs. B doping was found to suppress defects and improve electrical performance. By introducing a water-processed high-K ZrO2 dielectric, the TFTs exhibited excellent device performance and bias stress stability.

Summary: In this study, a water-casting method was proposed to produce high-permselectivity thin-film composite (TFC) membranes for hydrogen purification. The film integrity and thickness were controlled by adjusting the spreadability of the casting solution. Under optimized conditions, the water-cast TFC membrane showed high hydrogen permeance and selectivity, making it suitable for meeting the demand for pure hydrogen.

Summary: Copper nanoparticles (CuNPs) exhibit localized surface plasmon resonance (LSPR) effect, which is enhanced in Cu thin films composed of individual CuNPs due to LSPR coupling. However, oxidation of CuNPs leads to rapid LSPR damping in the thin films. This study uses the Discrete-dipole approximation method to simulate the influence of oxide shell thickness, ambient refractive index, CuNPs diameter, and inter-nanoparticle spacing on the coupled LSPR of CuNPs.

Summary: This research presents scaled ultrathin (about 3 nm) InGaO (IGO) thin film transistors (TFTs) with high-performance characteristics. The IGO channels, derived from atomic layer deposition (ALD), have a high In/Ga atomic ratio of approximately 86:14, resulting in a high electron mobility under a thin thickness. The IGO TFTs show excellent scaling behaviors and demonstrate good electrical characteristics, making them potential candidates for back-end-of-line (BEOL)-compatible monolithic 3D integration.

Summary: Exceeding the permitted levels of manganese and ammonium is a common occurrence in a water treatment plant in south China. A study found that an iron-manganese complex oxide film can effectively remove over 95% of the excess manganese and ammonium at a temperature of 20 degrees C and an alkalinity level of 30 mg/L. The research provides important insights for simultaneous removal of manganese and ammonium through catalytic oxidation.
