Abstract The mechanisms of plastic transport in rivers remain an important knowledge gap global pollution research and management. We investigated how river flows plastics' properties affect with a five‐point cross‐sectional field study the Hillsborough River Tampa (Florida, USA) using 500‐µm Neuston net Acoustic Doppler Current Profiler. conducted in‐depth analysis water velocity profiles as well concentrations properties, determining advective, vertical, lateral fluxes. Under calm flow...
Abstract Field data on plastic pollution is extremely limited in Southeast Asian rivers. Here we present the first field measurements of transport Mekong, based a comprehensive monitoring campaign during monsoon season confluence Tonle Sap, and Bassac rivers around Cambodia’s capital (Phnom Penh). For improved accuracy estimation loads distribution, combined Neuston net multipoint cross-sectional water sampling with acoustic Doppler current profiler high resolution measurements. During wet...
Temporal and spatial variability are thought to drive river plastic transport, but most field data collections limited sporadic sampling at one location, constraining our ability predict pollution accurately. In this study, we assessed the impact of seasonal longitudinal on loads collected during 18 months in Florida (USA). We used multipoint cross-sectional sampling, coupling a 500 μm Neuston net with an Acoustic Doppler Currency Profiler three sites along river, followed by laboratory...
Metal deterioration via corrosion is a ubiquitous and persistent problem. Ångström-scale, atomically thin 2D materials are promising candidates for effective, robust, economical passivation coatings due to their ultimate thinness excellent mechanical electrical properties. This review focuses on elucidating the mechanism of in mitigation related physicochemical properties variations, such as defects, out-of-plane deformations, interfacial states, temporal thickness etc. In addition, this...
Abstract Hierarchical heterostructures of two-dimensional (2D) nanomaterials are versatile platforms for nanoscale optoelectronics. Further coupling these 2D materials with plasmonic nanostructures, especially in non-close-packed morphologies, imparts new metastructural properties such as increased photosensitivity well spectral selectivity and range. However, the integration nanoparticles has largely been limited to lithographic patterning and/or undefined deposition metallic structures....
Understanding the phonon characteristics of two-dimensional (2D) molybdenum ditelluride (MoTe2) under strain is critical to manipulating its multiphysical properties. Although there have been numerous computational efforts elucidate strain-coupled properties monolayer MoTe2, empirical validation still lacking. In this work, 1H-MoTe2 uniaxial studied via in situ micro-Raman spectroscopy. Directionally dependent monotonic softening doubly degenerate in-plane E2g1 mode observed with increasing...

Abstract Goldbeating is the ancient craft of thinning bulk gold (Au) into gossamer leaves. Pioneered by Egyptian craftsmen, modern mechanized iterations this technique can fabricate sheets as thin ∼100 nm. We take inspiration from millennia-old and adapt it to nanoscale regime, using colloidally synthesized 0D/1D Au nanoparticles (AuNPs) highly ductile malleable nanoscopic ingots subjecting them solid-state, uniaxial compression. The applied stress induces anisotropic morphological...
Abstract Two-dimensional (2D) materials have recently garnered significant interest due to their novel and emergent properties. A plethora of 2D been discovered intensively studied, such as graphene, hexagonal boron nitride, transitionmetal dichalcogenides (TMDCs), other metallic compound MXenes (nitrides, phosphides, hydroxides), well elemental (borophene, germanene, phosphorene, silicene, etc.). Considering the widespread in conventional van der Waals materials, two-dimensional nanosheets...
