Summary: This research focuses on novel ecological materials for biomedical and cosmetic applications. The blends of bionanocellulose and poly(vinyl alcohol), BNC/PVA, were prepared and their properties were examined under UV radiation and high temperature. The results showed that UV irradiation increased the crystallinity degree and changed the mechanical properties of the samples. However, the effects induced by UV-irradiation did not significantly deteriorate the materials' properties designed for medical applications. Thermogravimetric analysis exhibited good thermal stability for all samples.

Summary: Polymer functionalization is a powerful method for preparing polymers with diverse structures without the need for monomer synthesis or polymerization reactions. This study demonstrates the Mitsunobu derivatization of poly(vinyl alcohol) (PVA) to convert hydroxyl groups into different functional groups. The partial acetalation strategy improves the solubility of PVA derivatives and allows for the production of functionalized copolymers. This method enables the convenient one-step preparation of transparent, colorless, flexible, and scalable UV-shielding membranes.

Summary: The Covid-19 pandemic has led to discussions about increased packaging and reduced reuse. Many countries are promoting the use of biodegradable polymers. This study investigated the properties of blends of poly(lactic acid) (PLA) and poly(vinyl alcohol) (PVAL) with the addition of monobutyl maleate (MBM) as a compatibilizer. The results showed that MBM acted as a plasticizer, improving the flexibility and adhesion of the blend films.

Summary: The study focuses on the piezoelectric properties of nano-graphene/polymer composites and the influence of heterogeneity, thermal properties, phase transitions, and kinetic processes in the polymer matrix on macroscopic electrical conductivity and interfacial polarization. Broadband Dielectric spectroscopy is used to analyze electron transport and trapping, with effects of the harmonic electric field on the volume modifications of electro-active PVdF grains observed. Additionally, the electro-activity of PVdF grains is found to have weak dependencies on dc conductivity and dielectric relaxation.

Summary: A series of poly(vinyl alcohol-co-vinyl acetal) gel electrolytes were prepared and assessed for their performance as electrode separators in alkaline water electrolysis. The membrane properties could be tuned by varying the degree of functionalization, and a membrane with moderate vinyl acetal content showed good mechanical robustness and ion conductivity. The membrane effectively prevented hydrogen crossover during alkaline water electrolysis tests. The strategies presented in this work have general relevance to the field for the development of new ion-solvating membrane systems.

Summary: Flexible zinc-air batteries (FZABs) based on poly(vinyl alcohol) (PVA) alkaline gel polymer electrolyte (GPE) have poor cycling life, mainly due to the decline of the OH- ion content in the PVA-KOH GPE. Factors such as the formation of ZnO and carbonate in the GPE, as well as its poor water retention capability, contribute to the decrease in OH- ion content. This study provides valuable theoretical guidance and reference for prolonging the cycle lifetime of FZABs using PVA-KOH GPE.

Summary: The study focused on the production of gelatin/polyvinylpyrrolidone/hydroxyethyl cellulose/glycerol porous matrices with microspheres made of sodium alginate or pectin and sodium alginate. Characterization of the microspheres was done using various techniques, showing that the two-component microspheres were slightly larger than single-ingredient microparticles. The addition of microspheres increased the stiffness and toughness of the prepared materials, but also accelerated the degradation rate of the matrices.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
