Summary: Conventional spectroscopic ellipsometry is not well suited for the characterization of non-periodic nanostructures or structured fields that are much smaller than the illumination spot size. Instead, imaging Mueller matrix ellipsometry, which can measure the complete Mueller matrix for each pixel in a microscope image of the sample, is highly useful in nanostructure characterization and defect inspection. In this study, the sensitivity of imaging Mueller matrix ellipsometry for sub-wavelength sized features in nanostructures was systematically examined using a custom-made Mueller matrix microscope. The results were compared with traceable atomic force microscopy measurements and the suitability of this measurement technique in optical nanometrology was discussed.

Summary: Mueller matrix ellipsometry (MME) is a powerful tool for nanomanufacturing. In this study, a rigorous coupled-wave analysis (RCWA) method was proposed to efficiently simulate the optical responses of multilayer nanostructures. By computing the local scattering matrices and integrating them into the global matrix, the corresponding Mueller matrix can be simulated quickly. The results demonstrate significant numerical improvements, highlighting the effectiveness of the RCWA method in metrological studies of multilayer nanodevices.

Summary: We propose a dual vortex retarder Mueller matrix ellipsometry (DVRMME) that can extract 16 Mueller matrix elements by analyzing a single intensity image. Two customized vortex quarter wave retarders (VQWRs) with different orders are employed to realize the spatial modulation in the polarization state generation (PSG) and polarization state analyzing (PSA) arms. The DVRMME has been constructed and demonstrated in experiment, with RMS errors of 16 Mueller matrix elements less than 0.0110, 0.0094, and 0.0180, and maximum absolute errors less than 0.0196, 0.0230, and 0.0352 for air, polarizer, and retarder respectively.

Summary: This research uses imaging Mueller matrix ellipsometry to analyze the birefringent properties of polycrystalline textured thin films with rotational domains, successfully determining the biaxial dielectric tensor. Strong intermolecular interactions near excitonic resonances cause the real permittivity to become strongly negative, which could be appealing for nanophotonic applications.

Summary: Optical anisotropy in SnSe is utilized to design broadband and incident-angle-modulation near-infrared polarizers, with high modulation efficiency and no energy consumption. The broadband polarizer has a bandwidth of 324 nm and an average extinction ratio above 23 dB, while the incident-angle-modulation polarizer dynamically and reversibly modulates its working wavelength with a maximum extinction ratio of 71 dB. The proposed design opens up possibilities for mass-production and integration of polarizing optical components based on low-symmetry materials.

Summary: We report the production of pullulan/chitosan/graphene oxide composite films. The addition of graphene oxide increases the film's roughness while maintaining good dispersion. The formation of the composite film is attributed to the strong interactions between pullulan and chitosan, as well as the hydrogen bonding between chitosan and graphene oxide. The dielectric constant, Young's modulus, and tensile strength of the films reach maximum values at a graphene oxide concentration of 1 μg mL(-1). At higher concentrations, the interfacial layers between the polymer matrix and graphene oxide overlap, affecting the dielectric constant and mechanical properties. The MTT assay shows that the composite films with a graphene oxide concentration of 1 μg mL(-1) are not cytotoxic. The 50% pullulan/50% chitosan + 1 μg mL(-1) graphene oxide composite film has remarkable properties for potential applications in the food, cosmetic, and pharmaceutical industries.

Summary: In this study, chitosan-gold nanocomposite thin films were synthesized by chemically reducing HAuCl4 in chitosan solutions, and the effects of HAuCl4/sodium citrate molar ratio on the structure, electrical, and relaxation properties were investigated. It was found that the HAuCl4/sodium citrate ratio influenced the size of gold particles, conductivity, Vogel temperature, and water content. Two relaxation processes were observed in the nanocomposites, which could be used for the design of functional materials.

Summary: In this study, hexagonal HAp nanofibers with preferential crystalline orientation were produced and mixed with chitosan to create composite materials. The morphology of the nanofibers exposed active chemical groups and ions on the surface, which interacted with chitosan to enhance the mechanical resistance of the composites. Additionally, mixing the nanofibers and chitosan using a sonotrode improved their dispersion within the matrix and prevented migration. The mechanical resistance of the composite materials was higher than that of similar materials made with commercial HAp powders.

Summary: This study provides a comprehensive analysis of the magnetization and effective perpendicular magnetic anisotropy (PMA) of epitaxial D0(22)-Mn3+xGa ultrathin films. The growth method significantly affects the uniaxial PMA and thickness of non-magnetic layers, while the saturation magnetization remains unchanged. These results can be explained by interface structural defects caused by lattice mismatch and growth method.

Summary: The green surface modification of graphene oxide (GO) using lysine (Lys) under different pH conditions was studied. At pH 2, ester bonds were formed on the GO surface, while at pH 9.8, C-N bonds were formed. At pH 14, chemical reduction of GO nanosheets occurred. The results suggest that controlled chemical functionalization/reduction of GO nanosheets can be achieved under specific pH conditions, benefiting their potential use in biological applications.

Summary: Chitosan hydrogels were prepared by freeze-drying at different concentrations and molecular weights, and sodium bicarbonate was used as a crosslinking agent for physical crosslinking of chitosan sponges. XPS analysis confirmed the physical crosslinking of chitosan hydrogels using sodium bicarbonate. The chitosan hydrogels exhibited semi-crystalline nature, highly porous structure, high water absorption, and thermal stability, as well as non-cytotoxicity towards HT29 cells. Therefore, physically crosslinked chitosan hydrogels show great potential as biomaterials for biomedical applications.

Summary: In this study, four polythiourethane films with different types of polyols and isocyanates were synthesized, characterized, and foamed. The results showed that the type of isocyanate greatly influenced the crystallinity and stiffness of the polymers, while the type of polyol modified the FT-IR spectra and the decomposition curve of the material with temperature. Furthermore, the choice of isocyanate also affected the properties of the foams obtained from the polymeric material.

Summary: This study experimentally assessed the hydrodynamic characteristics of supercritical-pressure R134a in a horizontal circular tube. It was found that the hydrodynamic characteristic curve of R134a under supercritical pressure does not have a negative-slope region but a transition region. The transition region becomes more evident with increasing heat flux, while it weakens with increasing pressure and inlet temperature. Moreover, the onset of the transition region shifts in the direction of high mass flow rate with increasing heat flux.

Summary: This research aimed to valorize brewery spent grain (BSG) using subcritical water hydrolysis (SWH) modified by six different natural deep eutectic solvents (DES) and determining their bipotentialities. The findings showed that BSG hydrolysates obtained through DES-induced SWH contained high levels of sugars, proteins, flavonoids, phenolic compounds, and essential amino acids. The hydrolysates also demonstrated antimicrobial activities, and the presence of bioactive compounds was confirmed through FT-IR analysis. This comprehensive profiling of bioactive compounds from BSG using DES-mediated SWH can contribute to the efficient valorization of BSG for industrial purposes.
