Summary: Grain boundaries in two-dimensional materials have a significant impact on various material properties, and predicting all possible GB formations is a challenge. A workflow based on evolutionary algorithm was introduced to explore possible GBs formed at a lateral 2D interface, with genetic operations performed in the near interface region for computational efficiency. Experimental results showed that low energy GBs are dominated by Stone-Wales defects, while higher energy structures exhibit an increasing population of heptagons and nine-membered rings forming seven-nine defect pairs.

Summary: Impurities in copper foil are hindering the scalable production of high-quality graphene by chemical vapor deposition. These impurities have two distinct origins: intrinsic impurities from the manufacturing process of the copper foils, and external silica contamination from the quartz tube. Adequate confinement can solve the problem of external contamination, while electropolishing is particularly effective in reducing the issue of intrinsic impurities.

Summary: In recent decades, there has been a shift in focus towards hybrid nanomaterial flows due to the increasing energy demand. However, there is still much to be learned about these flows. This analysis examines the non-linear flow and heat transfer towards a moving surface using scaling similarity transformations to convert equations. The study investigates the effect of non-dimensional parameters on skin friction and Nusselt number transfer rate for hybrid fluid (Graphene + Magnesium oxide) and ternary hybrid nanomaterial (Graphene + Zirconium oxide + Magnesium oxide) cases.

Summary: In this work, a series of large-sized 2D titanium nanomaterials with a unique heterogeneous nanostructure containing nanosized titanium, titanium oxide, and MXene-like phases were fabricated using the method of polymer surface buckling enabled exfoliation (PSBEE). These 2D titaniums exhibit both superb mechanical strength (6-13 GPa) and remarkable ductility (25-35%) at room temperature, surpassing all other titanium-based materials reported so far. Furthermore, the 2D titanium nanomaterials also showed good performance in triboelectric sensing and can be used to fabricate self-powered, on-skin conformal triboelectric sensors with good mechanical reliability.

Summary: A novel production scheme is proposed to neutralize the CO2 generated from natural gas-based hydrogen production by direct deposition of 2-dimensional carbon as a cement nanoadditive. This approach can significantly reduce carbon nanosheets costs and cement usage, leading to carbon-neutral hydrogen production.

Summary: Two-dimensional nanomaterials have made significant contributions to advancements in material sciences and nanotechnology. However, the translation of these materials in biomedicine is limited due to a lack of understanding and control over their interactions with complex biological systems. This review critically discusses the potential interactions between proteins and 2D nanomaterials, along with various analytical techniques that can be used to study and characterize these interactions.

Summary: In this study, a new class of piezoresistive nanocomposites was developed by mixing different types of 2D nanosheets. It was found that the conductivity of each nanocomposite type exhibited a different dependence on filler volume fraction, and they also showed different piezoresistive properties. This research expands the understanding of piezoresistive nanocomposites and provides a platform for the engineering of high-performance strain sensors.
