Summary: In this study, the influence of several parameters on the performance of electrochemical cocaine aptasensors based on large-size graphene oxide flakes was investigated. The results showed that physical adsorption-based aptasensors with NH2-modified aptamers exhibited good reproducibility, shelf-life stability, and high sensitivity, comparable to covalent immobilization-based aptasensors. It was also found that graphene oxide materials with high electrochemical surface area and standard rate constant of electron transfer can enhance sensing performance. The strong and fast adsorption of NH2-modified cocaine aptamers on the surface of large graphene oxide flakes makes the fabrication of sensing platforms simple and rapid, potentially simplifying the fabrication of sensors.

Summary: Cotton e-textiles were produced using two different types of graphene oxide. The first type was synthesized using the Hummers' method, while the second type was obtained through electrochemical exfoliation of graphite. It was found that e-textiles based on electrochemically exfoliated graphene had higher electrical conductivity and better washing and mechanical stress stability compared to those based on Hummers' method graphene oxide. The superior properties of electrochemically exfoliated graphene were attributed to its smaller lateral size and higher degree of sp(2) structure regeneration after reduction.

The modified graphene oxide exhibited higher adsorption capacity for Bisphenol A, Benzophenone-4, and Carbamazepine compared to unmodified graphene oxide and reduced graphene oxide. Molecular dynamics simulations showed increased interaction energies between the modified graphene oxide and contaminants, which can be attributed to the presence of amino acid side chains on the nanosheet surface.

Summary: In membrane-based water purification technology, the preparation conditions greatly affect the pore size distribution and dye removal efficiency of cellulose acetate membranes. Different fabrication methods and conditions, such as film casting speed, casted solution thickness, coagulation bath usage, and surfactant addition, significantly influence the membranes' pore size, porosity, and water permeability. The study also found that Azure A had better chemical affinity for cellulose acetate and was removed more efficiently, and both Azure A and Methyl Orange dye uptake followed a pseudo-second order model indicating chemisorption through valency forces.

Summary: In this study, we compared different materials in removing organic contaminants from water using Langmuir adsorption isotherms. We found that the removal efficiency reaches a limit at low concentrations and multi-step adsorption processes are more efficient than single-step adsorption with smaller amounts of adsorbent material. The concentration of the adsorbent strongly affects its performance. Furthermore, we emphasized the importance of reporting both Q(m) and K-L parameters for comparing materials tested under different experimental conditions in future work and reviews.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
