Bridging the gap between atomically thin semiconductors and metal leads

open access: yesNature Communications, 2022
Barrier-free metal-semiconductor interfaces are crucial to improve the performance of 2D electronic devices. Here, the authors report a strategy to induce local bonding distortion in 2D transition metal dichalcogenides via soft oxygen plasma treatments ...

Assessment of the impact of sensor error on the representativeness of population exposure to urban air pollutants

open access: yesEnvironment International, 2022
For the monitoring of urban air pollution, smart sensors are often seen as a welcome addition to fixed-site monitoring (FSM) networks. Due to price and simple installation, increases in spatial representation are thought to be achieved by large numbers ...

Assessment of the potential of MERIS near-infrared water vapour products to correct ASAR interferometric measurements [PDF]

open access: yes, 2006
Atmospheric water vapour is a major limitation for high precision Interferometric Synthetic Aperture Radar (InSAR) applications due to its significant impact on microwave signals.

Compact higher-order gas-kinetic schemes with spectral-like resolution for compressible flow simulations

open access: yesAdvances in Aerodynamics, 2019
In this paper, a class of compact higher-order gas-kinetic schemes (GKS) with spectral-like resolution will be presented. Based on the high-order gas evolution model, both the flux function and conservative flow variables in GKS can be evaluated ...

Anomalous Anderson localization behavior in gain-loss balanced non-Hermitian systems

open access: yesNanophotonics, 2020
It has been shown recently that the backscattering of wave propagation in one-dimensional disordered media can be entirely suppressed for normal incidence by adding sample-specific gain and loss components to the medium.

Clear-Water Scour at Pile Groups [PDF]

open access: yesJournal of Hydraulic Engineering, 2013
AbstractGroups of piles are frequently used as bridge foundations. Different group configurations, characterized by different pile spacing, skew-angle, number, and arrangement of pile group columns interact differently with the flow field and lead to different scour patterns and equilibrium scour depth.

Water-clear cell Parathyroid adenoma: rare case report [PDF]

open access: yes, 2018
ObjectiveWater-clear cell parathyroid adenoma (WCCA) is an extremely rare cause of primary hyperparathyroidism (PHPT). Our objective was to report a patient with a WCCA that was managed by our Department and to review the relevant literature in order to ...

Filamentous Algae Blooms in a Large, Clear-Water Lake: Potential Drivers and Reduced Benthic Primary Production [PDF]

open access: yes, 2022
An apparent proliferation of filamentous algal blooms (FABs) in pristine lakes around the world is a source of concern. However, little is known about the predominant drivers and effects of such FABs on lake ecosystems.

Subnatural-linewidth biphotons from a Doppler-broadened hot atomic vapour cell

open access: yesNature Communications, 2016
Quantum-network protocols based on photon-atom interfaces have stimulated a great demand for single-photon sources with narrow bandwidth. Here the authors report the generation of entangled photon pairs with controllable bandwidth and coherence time from
