Summary: The development of a new bifunctional reversible addition-fragmentation chain transfer (RAFT) agent allows for the synthesis of polymers with predetermined molecular weights and low dispersibilities, while also providing functionalities at both polymer termini that allow strong binding to graphene oxide (GO). By controlling the bifunctional RAFT agent, acrylonitrile-styrene-acrylate (ASA) copolymers with different types of acrylates have been synthesized, enabling access to polymers with diverse thermal and mechanical properties. The strong binding between GO and the synthesized polymers has been verified, leading to the preparation of polymer/GO composites with varied tensile strengths and conductivity properties similar to semiconductors.

Summary: The GO-CE-CA-AgNCs, which consists of beta-catechin mediated synthesized silver nanoparticles embedded in cellulose-graphene oxide nanocomposite, show improved antibacterial activity. The size of the AgNPs is 14.2 +/- 13.83 nm and the zeta potential is -35.9 +/- 0.14 mV. FT-IR analysis confirms the presence of GO, CE, CA, and AgNPs in GO-CE-CA-AgNCs. XRD pattern indicates the crystalline nature of GO-CE-CA-AgNCs. TEM images confirm the coating of AgNPs on the CE-GO sheets. The GO-CE-CA-AgNCs show potential as antibacterial agents against both Gram-positive and negative bacterial pathogens.

Summary: This article explores a method of increasing the specificity and biocompatibility of cytostatic drugs by creating conjugates with graphene oxide. Graphene oxide is a new and promising material in the field of nanomedicine due to its reactive and developed surface, which allows for functionalization and immobilization of drugs. The study focuses on a non-covalent conjugate of graphene oxide and a alkylating agent, and evaluates its biocompatibility through various tests. The results show that the conjugate is hemocompatible, exhibits antioxidant activity, induces photoinduced hemolysis, and demonstrates dose-dependent genotoxicity and cytotoxicity towards specific cell lines.

Summary: The scarcity of river sand has led to the use of sea sand inappropriately in many countries, causing corrosion and structural failures due to chloride ions. This study investigates a novel pre-treatment method using graphene oxide (GO) coating on amino-functionalized sea sand (GOCAFSS) to suppress chloride leaching and improve the performance of sea sand cement-based composites. The results show that GO can enhance chloride binding capacity by promoting the formation of calcium silicate hydrate (C-S-H) and Friedel's salts (FS), effectively controlling harmful chloride ions.

Summary: Reliable and straightforward characterization and analysis of carbon-based nanomaterials on the atomic level is crucial. Combination of highly surface sensitive x-ray photoelectron (XP) spectroscopy and near edge x-ray absorption fine structure spectroscopy (NEXAFS) is used to study and quantify the covalent functionalization of nanographene and single-walled carbon nanotubes with nitrene [2 + 1]-cycloaddition. The results show preserved n-conjugated system of functionalized carbon-based nanomaterials according to NEXAFS analysis, which is challenging to prove with XP spectroscopy alone. The combination of analytical approaches is suited to study post-modification reactions of functionalized carbon-based nanomaterials.

Summary: This research investigates a rotary disk with variable cross-section and incompressible hyperelastic material with functionally graded properties in large hyperelastic deformations. The changes in cross-section and material properties are expressed using a power relation, with (m) representing the changes in cross-section and (n) representing the manner of changes in material properties. The constants used for hyperelastic material have been obtained from experimental data. The obtained equations have been solved for different m, n, and angular velocity values, and the values of radial stresses, tangential stresses, and elongation have been compared. The results show that m and n have a significant impact on disk behavior, and the expected behavior of the disk can be obtained by an optimal selection of these two parameters.
