        <description><![CDATA[The recently synthesized 30° twisted bilayer graphene (30°-TBG) systems are unique quasicrystal systems possessing dodecagonal symmetry with graphene’s relativistic properties. We employ a real-space numerical atomistic framework that respects both the dodecagonal rotational symmetry and the massless Dirac nature of the electrons to describe the local density of states of the system. The approach we employ is very efficiency for systems with very large unit cells and does not rely on periodic boundary conditions. These features allow us to address a broad class of multilayer two-dimensional crystal with incommensurate configurations, particularly TBGs. Our results reveal that the 30°-TBG electronic spectrum consist of extended states together with a set of localized wave functions. The localized states exhibit fractal patterns consistent with the quasicrystal tiling.]]></description>

        <description><![CDATA[The omnipresence of emerging contaminants in the aquatic environment is indisputable. These contaminants include chemical substances not removed in traditional water and sewage treatment processes. To ensure the quality of water and healthy aquatic ecosystems, new treatment technologies and materials are essential to effectively control the presence of these contaminants in the aquatic environment. More than that, it is important to know how molecules interact with these new materials. A low-cost alternative currently available is adsorption. Despite this method being widely studied, describing the interaction mechanisms between the materials and the analytes is not usual, limiting the obtainment of more efficient materials. Thus, the objective of this work was to understand, in a theoretical-experimental way, the forms of interaction in the adsorption of the drug paracetamol, widely used worldwide, in materials based on graphene with different chemical and structural properties. For this, kinetic and isothermal experimental studies were carried out using four materials that contemplated different dimensions, pore sizes, and oxidation degrees. In theoretical studies, density functional theory (DFT) simulations were performed to cover quantum details, revealing how paracetamol interacts with different graphene structures. According to theoretical studies, binding energies, binding distances, and charge transfer between oxidized graphene and paracetamol drug are compatible with physical adsorption, strongly dependent on the type and number of functional groups on the graphene surface. These results agree with the experimental data where the highest adsorptions were observed precisely for materials containing a higher proportion of functional groups and where these groups are more available (more porous), with adsorptive capacities reaching 235.7 mg/g. Our findings contribute to scientific knowledge about using graphene structures as an adsorbent material, providing a solid basis for future studies and developing more efficient and advanced water treatment technologies.]]></description>

        <description><![CDATA[The infiltration of pesticides into agricultural soils has emerged as a critical concern, posing substantial threats to the agriculture industry due to soil and water contamination. The detection of these contaminants is critical towards implementing effective environmental remediation strategies and achieving ecosystem sustainability. Electrochemical sensor technology has been demonstrated to be highly promising for this application. Graphene and its derivatives and composites are widely used as modifying materials in these sensors to enhance their analytical performance. This short review discusses recent progress in the application of graphene-based electrochemical sensors in three-electrode and field-effect transistor configurations for the detection of pesticides posing significant risks to the agricultural sector. It highlights the growing significance of graphene-based sensors in mitigating pesticide-related environmental challenges and underscores their role in ensuring the health and diversity of agricultural ecosystems.]]></description>

        <description><![CDATA[Maintaining the properties of nanocomposites obtained at the laboratory scale when evolving to pilot and industrial scales is a great challenge. In this work, the route for a 3000-fold increase in scale between the laboratory and production in an industrial environment was conducted in two stages–Pilot 1 and Pilot 2–to obtain polymeric nanocomposite plates for pilot testing. The nanocomposite was based on ultrahigh molecular weight polyethylene (UHMWPE) and reduced graphene oxide (rGO), and several different operations were optimized for complete scale-up, i.e., 1) production of reduced graphite oxide (rGrO); 2) exfoliation of rGrO; 3) milling of rGO with UHMWPE in a ball mill to produce masterbatch; and 4) RAM extrusion to produce the plates. All these steps were accompanied by characterizations that show the quality of the nanomaterial, masterbatch and nanocomposite plates. The gains in nanocomposite properties with 0.25 wt% rGO with respect to UHMWPE were ∼45% in elastic modulus, ∼50% in hardness, ∼25% in impact strength and 15% in abrasion wear (two-body test). The nanocomposite surfaces after wear tests are more hydrophobic than UHWWPE. The Pilot 1 results were generally superior to the Pilot 2 results, probably due to the very different thicknesses of the plates, i.e., 10 mm in Pilot 1 and 40 mm in Pilot 2. The improvement in different properties confirms the multifunctionality of the nanocomposite UHMWPE/rGO now produced on a pilot scale.]]></description>
