Summary: In this study, tunable mesoporous silica films were characterized using positron annihilation gamma-ray energy spectroscopy, positron annihilation lifetime spectroscopy, ellipsometric porosimetry, and heptane adsorption. The results showed that ellipsometric porosimetry combined with heptane adsorption is a highly sensitive method for calibrating mesopore size in interconnected films, while positron annihilation lifetime spectroscopy is a novel complementary tool for characterizing closed and open pores.

Summary: An effective antimicrobial surface film based on sustainable microfibrillated cellulose was developed in this study. The porous cellulose thin film showed excellent antimicrobial performance against both Gram-negative and Gram-positive bacteria, and rapid inactivation effect against SARS-CoV-2. It also exhibited nearly 100% resistance to scraping in dry conditions and good removability when wetted with water, making it suitable for daily use.

Summary: The temperature range for the formation of single phase, orthorhombic MoAlB synthesized by magnetron sputtering is 450-650 degrees C, with amorphous films forming at lower temperatures and impurity phases forming at 700 degrees C. Diffusion mechanisms play a crucial role in the synthesis of fully dense MoAlB films at 600 degrees C, with surface diffusion mediating below 545 degrees C and bulk diffusion being activated between 545 and 575 degrees C.

Summary: Novel biomaterials with excellent bone regeneration potential were synthesized from marine-derived hydroxyapatite by pulsed laser deposition. The rough surfaces of the thin films promoted cell adhesion and implant anchorage. The thin films exhibited strong hydrophilic behavior, superior bonding strength adherence, low cytotoxicity, and effective antimicrobial activity. These cost-effective materials from sustainable sources are recommended for the development of innovative coatings for metallic dental implants.

Summary: Stable chitosan thin films can serve as promising substrates for creating nanometric peptide-bound polyglucosamine layers, with structural similarities to bacterial peptidoglycans. Various characterization techniques were employed to investigate the surface chemistry and confirm the acetylation and coupling of peptides on the chitosan films, indicating potential to mimic bacterial cell wall structures.

Summary: We report on the superconductivity in Nd1-xEuxNiO2, where Eu is used as a 4f dopant. By employing an in situ molecular beam epitaxy reduction process, we achieve the superconducting phase, providing an alternative method to induce superconductivity in infinite-layer nickelates compared to the ex situ CaH2 reduction process. The Nd1-xEuxNiO2 samples exhibit a step-terrace surface structure, have a T-c onset of 21 K at x = 0.25, and show a large upper critical field possibly due to Eu 4f doping.

Summary: This study demonstrates a method to significantly reduce the grain boundary density in Sb2S3 films by incorporating an appropriate amount of Ce3+ into the precursor solution. The formation of an ultrathin Ce2S3 layer at the CdS/Sb2S3 interface is found to be critical in promoting nucleation and lateral grain growth of Sb2S3. This work achieves high-performance Sb2S3 solar cells with impressive power conversion efficiency and open-circuit voltage, providing a strategy for enhancing the performance of Sb2S3 absorber films.

Summary: A simple drop-casting technique was used to prepare tin selenide thin films with triethanolamine as complexing agent. The synthesized films were analyzed for their surface morphology, structure, electrical conductivity, and optical properties. The results showed that the films had an orthorhombic crystal structure, good continuity, and were suitable for use as an absorber layer in solar cells.

Summary: Open framework materials (OFMs) in the form of thin films have great potential as electrocatalysts, but their development is still in its early stages, with a need for further research. Controlling the thickness, roughness, and particle sizes of the films is crucial for their electrocatalytic activities.

Summary: This article proposes a facile one-step method for forming silver thin-film nanostructures on Al2O3 substrates using the hydrothermal method. The study shows the dependency of the SERS effect intensity of the formed films on synthesis conditions, additional temperature treatment, and laser radiation wavelength. The article also demonstrates the effect of synthesis temperature on the particle size, crystal structure, and microstructure features of the obtained thin films based on silver nanoparticles. Additionally, the study reveals the factors associated with the properties of the obtained SERS substrates and the parameters of recording the spectra that affect the amplification factor of the spectral lines intensity of the analyte.
