Summary: In this study, a smooth functional film with good mechanical strength was designed and prepared by combining graphene oxide (GO) with polyethylene glycol (PEG), effectively reducing friction and wear. The effects of lubrication for the cases of flexible lubricating film, no film, and single film were analyzed. The results show that the PEG and GO mixture significantly improves the thermal stability, film forming properties, and mechanical properties of GO-PEG composites, with a 74% reduction in friction coefficient and 70% reduction in wear rate compared to uncoated surfaces.

Summary: The study reports on the synthesis and temperature-responsive properties of poly(PEGMA) hydrogel thin films. Surface-attached poly(PEGMA) hydrogel films were synthesized using a simple, versatile, and well-controlled thiol-ene click reaction method, with the transition temperature finely tunable by adjusting the number of PEG units. The LCST properties of the hydrogel films are not sensitive to salt, holding promise for applications in biology such as injectable hydrogels, drug delivery systems, microfluidic valves, and flow switches for biotechnologies.

Summary: This study investigates the adsorption behavior of polymers on graphene oxide (GO) nanosheets by preparing a series of PEG/GO nanohybrids with different experimental parameters. The results show that the adsorption amount of PEG onto GO is influenced by factors such as mixing time, molecular weight, mixing ratio, and washing procedure. Additionally, the adsorption onto GO reduces the crystallinity of PEGs.

Summary: Recent studies have shown that nanofluids have the potential to enhance the heat transfer properties of coolants in car radiators. By combining ethylene glycol and deionized water with graphene oxide nanoparticles, the heat transfer characteristics of the nanofluids were experimentally investigated. The optimized combination of 60% ethylene glycol, 40% deionized water, and 0.1 wt% graphene oxide exhibited higher heat transfer characteristics and showed potential for reducing frontal area and improving fuel efficiency in industrial design.

Summary: Graphene Oxide (GO) has been difficult to translate into clinical applications due to non-specific protein adsorption and poor stability. This study establishes a new method for functionalizing GO with poly(ethylene glycol) (PEG) using the Steglich esterification reaction, improving the stability of GO and PEG interaction through covalent bond formation. The proposed methodology successfully demonstrates the attachment of PEG to the hydroxyl group of GO sheets, as confirmed by spectroscopic and microscopic analysis.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
