Strong-coupling of monolayer metal dichalcogenide semiconductors with light offers encouraging prospects for realistic exciton devices at room temperature. However, the nature this coupling depends extremely sensitively on optical confinement and orientation electronic dipoles fields. Here, we show how plasmon strong can be achieved in compact robust easily-assembled gold nano-gap resonators We prove that is impossible monolayers due to large coherence size, but resolve clear anti-crossings...
Coupling noble metal nanoparticles by a 1 nm gap to an underlying gold mirror confines light extremely small volumes, useful for sensing on the nanoscale. Individually measuring 10 000 of such increasing size dramatically shows different scaling their optical scattering (far-field) and surface-enhanced Raman emission (SERS, near-field). Linear red-shifts coupled plasmon modes are seen with size, matching theory. The total SERS from few hundred molecules under each nanoparticle increases...
Renewable energy has become an important alternative to fossil energy, as it is associated with lower greenhouse gas emissions. However, the intermittent characteristic of renewables urges for storage systems, which play role in matching supply and demand renewable-based electricity. The life cycle these systems results environmental burdens, are investigated this study, focusing on lithium-ion vanadium flow batteries renewable (solar wind) grid applications. impacts assessed through a...
The precise structural details of metallic nanogaps within optical antennae are found to dramatically modify the plasmonic response, producing a complex pattern electromagnetic modes that can be directly observed in scattering experiments. We analyze this situation theoretically nanoparticle-on-mirror construct, which forms nanogap sensitive even atomic-scale restructuring nanoparticle morphology. focus on effect faceting, allows formation ultrathin cavities between particle and underlying...
Plasmonic nanocavities with sub-5-nm gaps between nanoparticles support multiple resonances possessing ultra-high-field confinement and enhancements. Here we systematically compare the two fundamentally different resonant gap modes: transverse waveguide (s) antenna modes (l), which, despite both tightly confining light within gap, have completely near-field far-field radiation patterns. By varying size, experimentally theoretically, show how changing nanoparticle shape from sphere to cube...
Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. total, 5023 curves were collected across all continents in SWIG These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its extensive geographical coverage, cover research...
Nanometer-sized gaps between plasmonically coupled adjacent metal nanoparticles enclose extremely localized optical fields, which are strongly enhanced. This enables the dynamic investigation of nanoscopic amounts material in gap using interrogation. Here we use impinging light to directly tune resonances inside plasmonic nanocavity formed single gold and a surface, filled with only yoctograms semiconductor. The faces separated by either monolayers molybdenum disulfide (MoS2) or...
Two electrolysis technologies fed with renewable energy sources are promising for the production of CO2-free hydrogen and enabling transition to a society: Alkaline Electrolyte (AE) Polymer Membrane (PEM). However, limited information exists on potential environmental impacts these sustainable innovations when operating large-scale. To fill this gap, performance AE PEM systems is compared, using ex-ante Life Cycle Assessment (LCA), technology analysis exploratory scenarios which refined...
Abstract The massive deployment of clean energy technologies plays a vital role in the strategy to attain carbon neutrality by 2050 and allow subsequent negative CO 2 emissions order achieve our climate goals. An emerging challenge, known as ‘From Emissions Resources,’ highlights significant increase demand for critical raw materials (CRMs) technologies. Despite presence ample geological reserves, ensuring sustainable access these is crucial successful transition energy, taking into account...
Simulation of soil moisture content requires effective hydraulic parameters that are valid at the modelling scale. This study investigates how these can be estimated by inverse using measurements 25 locations three different depths (at surface, 30 and 60 cm depth) on an 80 20 m hillslope. The presents two global sensitivity analyses to investigate in simulated used a one-dimensional unsaturated zone model based Richards' equation.

Summary It is well established that dissolved organic matter (DOM) mobilizes copper (Cu) in soils but it unknown to what extent variable DOM quality affects this. During a 5 month period, 250 leachates of an uncontaminated agricultural soil were sampled at 45 cm depth using passive capillary wick samplers. The Cu and carbon (DOC) concentrations varied sevenfold weakly correlated ( r = 0.56). [Cu] : [DOC] ratio fivefold exhibited significant positive correlation 0.77) with the specific...

Plasmonic coupling of gold nanoparticles to a surface creates intense plasmonic hot spots with large electromagnetic field-enhancements within the cavity formed by two metallic surfaces. The localised field in such structures is extremely sensitive morphological fluctuations and subtle changes dielectric properties contents. Here, we present an optical method that pins down gap contents high sensitivity, termed normalising plasmon resonance (NPR) spectroscopy. We use this on variety...
