Surface-Enhanced Raman Scattering-Based Surface Chemotaxonomy: Combining Bacteria Extracellular Matrices and Machine Learning for Rapid and Universal Species Identification
Publication Type: Periodical
Source(s): ACS Nano; November 2023, Vol. 17 Issue: 22 p23132-23143, 12p
Abstract: Rapid, universal, and accurate identification of bacteria in their natural states is necessary for on-site environmental monitoring and fundamental microbial research. Surface-enhanced Raman scattering (SERS) spectroscopy emerges as an attractive tool ...
Pressure Dependence of Intra- and Interlayer Excitons in 2H-MoS2Bilayers
Publication Type: Periodical
Source(s): Nano Letters; October 2023, Vol. 23 Issue: 19 p8947-8952, 6p
Abstract: The optical and electronic properties of multilayer transition metal dichalcogenides differ significantly from their monolayer counterparts due to interlayer interactions. The separation of individual layers can be tuned in a controlled way by applying...
Exciton Fine Structure of CsPbCl3Nanocrystals: An Interplay of Electron–Hole Exchange Interaction, Crystal Structure, Shape Anisotropy, and Dielectric Mismatch
Publication Type: Periodical
Source(s): ACS Nano; July 2023, Vol. 17 Issue: 13 p12266-12277, 12p
Abstract: In the semiconducting perovskite materials family, the cesium-lead-chloride compound (CsPbCl3) supports robust excitons characterized by a blue-shifted transition and the largest binding energy, thus presenting a high potential to achieve demanding sol...
A Constrained Assembly Strategy for High-Strength Natural Nanoclay Film
Publication Type: Periodical
Source(s): ACS Nano; April 2022, Vol. 16 Issue: 4 p6224-6232, 9p
Abstract: Developing high-performance materials from existing natural materials is highly desired because of their environmental friendliness and low cost; two-dimensional nanoclay exfoliated from layered silicate minerals is a good building block to construct m...
Identification of Exciton Complexes in Charge-Tunable Janus WSeSMonolayers
Publication Type: Periodical
Source(s): ACS Nano; April 2023, Vol. 17 Issue: 8 p7326-7334, 9p
Abstract: Janus transition-metal dichalcogenide monolayers are artificial materials, where one plane of chalcogen atoms is replaced by chalcogen atoms of a different type. Theory predicts an in-built out-of-plane electric field, giving rise to long-lived, dipola...
Extreme Dynamic Performance of Nanofiber Mats under Supersonic Impacts Mediated by Interfacial Hydrogen Bonds
Publication Type: Periodical
Source(s): ACS Nano; December 2021, Vol. 15 Issue: 12 p19945-19955, 11p
Abstract: Achieving extreme dynamic performance in nanofibrous materials requires synergistic exploitation of intrinsic nanofiber properties and inter-fiber interactions. Regardless of the superior intrinsic stiffness and strength of carbon nanotubes (CNTs), the...
Increased Intraband Transitions in Smaller Gold Nanorods Enhance Light Emission
Publication Type: Periodical
Source(s): ACS Nano; November 2020, Vol. 14 Issue: 11 p15757-15765, 9p
Abstract: Photoinduced light emission from plasmonic nanoparticles has attracted considerable interest within the scientific community because of its potential applications in sensing, imaging, and nanothermometry. One of the suggested mechanisms for the light e...
Quantum Hall Effect Measurement of Spin–Orbit Coupling Strengths in Ultraclean Bilayer Graphene/WSe2Heterostructures
Publication Type: Periodical
Source(s): Nano Letters; October 2019, Vol. 19 Issue: 10 p7028-7034, 7p
Abstract: We study proximity-induced spin–orbit coupling (SOC) in bilayer graphene/few-layer WSe2heterostructure devices. Contact mode atomic force microscopy (AFM) cleaning yields ultraclean interfaces and high-mobility devices. In a perpendicular magnetic fiel...
