Summary: Materials with thickness ranging from a few nanometers to a single atomic layer offer unique opportunities to explore new phases of matter confined to two dimensions. The reduction in dimensionality significantly impacts particle-particle Coulomb interaction, pushing the boundaries of established solid state theoretical approaches. Advances in computational techniques and close interaction with experiments have led to the discovery of exceptional properties in two-dimensional materials, inspiring new paradigms in device design. Challenges arise in simulating and interpreting the properties of two-dimensional constrained fermions and quasiparticles, pointing towards future directions in research in this field.

Summary: There is a growing interest in using 2D materials to replace traditional materials in microelectronics and sensing. However, the thin nature of these materials makes them susceptible to variations caused by their environment, which can affect their properties. Understanding and controlling these factors are significant challenges for the adoption of 2D materials in industrial applications.

Summary: Polarisation curves are widely used for corrosion behaviour, kinetics and mechanisms studies, but interpreting them can be challenging for non-uniform electrode surfaces as they combine different local polarisation curves that cannot be individually assessed. This short communication introduces a new method for measuring local polarisation curves using an electrochemically integrated electrode array that allows site-specific measurements. The method is successfully demonstrated by measuring and interpreting local polarisation curves from steel surfaces exposed to waterline corrosion environment.

Summary: This review focuses on the theoretical basis of classical and quantum confinement effects in two-dimensional (2D) electrode materials and discusses the recent experimental advances in this area. It covers topics such as ion transport, mass and electron transport mechanisms, and the impact of step edges, defects, and dopants on electron transport in 2D electrode materials. Opportunities for further research involving first-principles calculations, molecular dynamics simulations, and the development of analytical theories are also identified.

Summary: This study investigates the influence of a plasma electrolytic oxidation (PEO) surface treatment on a medical-grade WE43-based magnesium alloy. The research finds that the PEO modified group has significantly lower corrosion rate and higher mechanical properties compared to the unmodified group.

Summary: A multi-physics coupled model is proposed to investigate the temporal and spatial evolution of galvanic corrosion with an anisotropic deposition layer, revealing the coupled relationship between electrochemical behavior and physical processes. The deposition layer with anisotropism generates a non-uniform conductivity and current density distribution. The competition between transport processes and electrochemical reactions determines the spatial-temporal evolution of ion concentration.

Summary: The micro-galvanic interactions between Cu-Fe-Mn-Li-containing aluminides and the alloy matrix of aluminium alloy AA2099 during chloride-induced corrosion were investigated in-situ, showing that the aluminides can ennoble their neighbouring matrix sites and the anode-to-cathode ratio has dynamic changes during corrosion. Higher local V-CPD activities were recorded during the earliest stages of corrosion, indicating a unique phenomenon in Al-Li AA2099 not seen in other aluminium alloys.

Summary: This paper presents the elliptical harmonic method for gravity computation of 2D bodies with constant, polynomial, and exponential density distributions. The method converts surface integrals into line integrals for evaluating the gravity field, considering the effects of discontinuities in elliptical coordinates. The method shows convergence, accuracy, and stability in numerical experiments with tested bodies, demonstrating advantages over the circular harmonic approach.

Summary: This study presents a computational framework that investigates the effect of localised surface-based corrosion on the mechanical performance of a magnesium-based alloy. Using a verified corrosion modelling approach, a quantitative relationship between mechanical integrity and corrosion features was established, with the minimal cross-sectional area parameter being the strongest predictor.

Summary: Future salt reactors require different materials for neutron moderation (graphite) and containment (structural metals). However, interactions between graphite and metal in a salt medium can accelerate metal corrosion and change graphite's surface. To reduce these interactions, a novel pyrolytic boron nitride coating on graphite was investigated, and tests revealed that it reduces interactions between stainless steel and uncoated graphite.

Summary: The study demonstrates that 2D Navier-Stokes and Euler flows with localized vorticity exhibit regular structures in the far field, with the level lines of velocity components forming symmetric regular polygons. The shape of the polygon is dependent on the total circulation and integrability of the velocity.
