Summary: A polycondensate-coated cellulose nanofiber (CNF) hybrid was designed and used as a nanofiller for fabricating CNF-reinforced polylactic acid (PLA) composites. The polycondensate coatings effectively promoted the dispersion of CNFs and enhanced the interfacial compatibility between CNFs and PLA. The resulting composites exhibited significant improvements in processing, mechanical, and thermal properties.

Summary: The threat of epidemic outbreaks is increasing due to the exponential growth of the global population and human mobility. Personal protective equipment, such as face masks, are crucial in protecting against viral infections. However, the uncontrolled manufacture and disposal techniques of face masks pose potential threats. Improper solid waste management contributes to viral propagation and increases biomedical waste. The chemical constituents in single-use face masks, including plasticisers and flame retardants, can lead to health issues. Despite extensive research, the efficacy and post-disposal impact of personal protective equipment are yet to be adequately explored. This review provides an overview of different forms of personal protective equipment, discusses proper waste management techniques, and examines the innovations and impact of face masks on human health and the environment. Strategies for safe and proper solid waste disposal are also discussed, along with the development of a 3D model of a face mask using computational fluid dynamics. The review concludes with possibilities for future advancements and promising research avenues in personal protective equipment.

Summary: The study investigated the combined effects of CNF nucleation and PLA-g-MA compatibilization on the crystallization kinetics and mechanical properties of polylactic acid (PLA). While PLA-g-MA improved nucleation in PLA/PLA-g-MA, it did not enhance crystallization rate in PLA/PLA-g-MA/CNF3 compared to uncompatibilized PLA/CNF3. Tensile strength decreased with more PLA-g-MA, but Young's modulus significantly increased, contributing to the rigidity of the PLA nanocomposites.

Summary: The study found that adding cellulose acetate can enhance the membrane's permeability, while porogens can increase the membrane's hydrophilicity, dialysis coefficient, and nutrient release rate. There was not a significant difference in membrane performance with different porogens, but urea coated with membranes containing nano-SiO(2) and PEG showed higher nutrient release rates.

Summary: The study investigated the nucleation effect of incorporating cellulose nanofibers (CNF) into polylactic acid (PLA), showing that CNF at 3 wt.% significantly improved both the crystallization rate and mechanical properties of PLA. However, at CNF content higher than 3 wt.%, the crystallization rate decreased, indicating possible agglomeration. CNF at 3 wt.% plays a crucial role in enhancing the performance of PLA.

Summary: G.V. Samsonov, a Russian-Ukrainian scientist, made significant contributions to materials science, although much of his work remained hidden due to political reasons. One of his important theoretical contributions is the configurational model of the solid state based on the statistical weight of atoms with stable configuration. This model was tested to explain the effects of divalent transition elements on the solubility of hydroxyapatite when they act as dopants.

Summary: Type 1 diabetes is caused by inadequate insulin production, which can be treated with insulin injections but may not accurately respond to glucose concentrations. This study proposed a novel approach by using polymeric reservoirs containing insulin and glucose-responsive metallic nanoparticle precursors to release insulin based on the glucose concentration. The release of insulin was directly proportional to the glucose concentration, suggesting the potential for a glucose-controlled insulin delivery system to mitigate hyperglycemia symptoms in diabetes patients.

Summary: Colorectal cancer is a common cause of cancer-related deaths globally, with increasing incidence among young individuals. The tumor microenvironment in colorectal cancer is highly heterogeneous and immunosuppressive. Tumor necrosis factors (TNFs) and TNF receptor 2 (TNFR2) play critical roles in the development of colorectal cancer by enhancing the immunosuppressive activity of cancer cells. However, the exact mechanism of TNFR2 in regulating colorectal cancer prognosis is still unclear. Further studies on TNFR2 downstream signaling are needed to unlock its potential as a therapeutic agent and cancer biomarker.

Summary: The recipe for making Turkish coffee in some parts of former Yugoslavia includes diluting the liquid with lukewarm water before it reaches the boiling point. This dilution step was used as inspiration for a stabilization step in the synthesis of fine particle colloids. Implementing this step improved the stability of hydroxyapatite nanoparticles during precipitation. The unconventional protocol resulted in an increase in crystallinity and stability, likely due to complex recrystallization mechanisms and changes in surface order and charge screening.

Summary: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a global pandemic of coronavirus disease (COVID-19) and the current approved vaccines have shown considerable efficacy. However, the ongoing pandemic and the potential emergence of new strains highlight the need for further vaccine development and improvement. Subunit vaccines, based on synthetic peptides or recombinant proteins, have advantages such as safety and precise immune targeting, making them a promising option for widespread global use. This review article summarizes the current knowledge on different vaccine platforms, with a focus on subunit vaccines and their advancements in clinical trials against COVID-19.

Summary: Despite global advancements in science and technology, the disparity in access to cutting-edge medical technologies continues to increase, exacerbating global economic inequalities. This study proposes a method to quantify technology transferability and tests it on twelve state-of-the-art medical technologies and three comparatively impoverished regions. The analysis reveals that the transferability of technologies is determined by a complex network of factors encompassing science, technology, infrastructure, socioeconomics, and culture. The study highlights the importance of incorporating socioeconomic and humanistic factors into models assessing the social value of technologies.
