Label-free screening of biochemical changes in macrophage-like cells following MoS2 exposure using Raman micro-spectroscopy
(2021)The emergence of large scale production techniques for 2D particulate materials has dramatically increased their applications potential. Understanding the interactions of biological cells with such particulate material is ... -
Langmuir probe measurements and mass spectrometry of plasma plumes generated by laser ablation of La0.4Ca0.6MnO3
(2014)The plasma formed in vacuum by UV nanosecond laser ablation of La0.4Ca0.6MnO3 in the fluence range of 0.8 to 1.9 J cm−2 using both Langmuir probe analysis and energy-resolved mass spectrometry has been studied. Mass ... -
Large infrared nonlinear optical response of C60.
(1991)C60 buckminsterfullerene exhibits a large ultrafast third-order nonlinear optical response. Degenerate four-wave-mixing measurements in C60-benzene solutions were performed using 50-psec pulses at l.064Itm.The magnitude ... -
Large magnetorefractive effect in magnetite
(2010)We carried out a magneto-optical spectroscopic study of magnetite (Fe3O4) thin films and single crystals at optical wavelengths. We observed a relevant quadratic magneto-optic contribution that can be notably larger than ... -
Large-Scale Exfoliation of Inorganic Layered Compounds in Aqueous Surfactant Solutions
(2011)Thumbnail image of graphical abstract A method to exfoliate MoS2 in large quantities in surfactant-water solutions is described. The layered material tends to be exfoliated as dispersions of thin, relatively defect-free ... -
Large-scale production of size-controlled MoS2 nanosheets by shear exfoliation
(2015)In order to fulfil their potential for applications, it will be necessary to develop large-scale production methods for two-dimensional (2D) inorganic nanosheets. Here we demonstrate the large-scale shear-exfoliation of ... -
Lattice distortion effects on the magneto-structural phase transition of MnAs.
(2005)We present a systematic experimental and theoretical study of the first-order phase transition of epitaxially grown MnAs thin films under biaxial tensile stress. Our results give direct information on the dependence of the ... -
LEMUR: Large European Module for solar Ultraviolet Research. European contribution to JAXA's Solar-C mission
(2012)Understanding the solar outer atmosphere requires concerted, simultaneous solar observations from the visible to the vacuum ultraviolet (VUV) and soft X-rays, at high spatial resolution (between 0.1" and 0.3"), at high ... -
Light amplification and lasing in a (meta-phenylene vinylene) copolymer
(2003)We report on single pass optical gain and lasing measurements on a blue-emitting copolymer, poly ~ m -phenylene vinylene-co-2,5-dioctyloxy- p -phenylene vinylene ! under 0.5 ns pulsed photoexcitation. This soluble ... -
The Limit of Spin Lifetime in Solid-State Electronic Spins
(2020)The development of spin qubits for quantum technologies requires their protection from the main source of finite-temperature decoherence: atomic vibrations. Here we eliminate one of the main barriers to the progress in ... -
Linear and nonlinear waveguiding in Rhodamine-doped
(1991)Planar waveguiding of 350-ps pulses, at a wavelength in the region of the long-wavelength tail of the absorption, is observed by coupling by prism into spun films of Rhodamine-B-doped epoxy films. In a 13-?.m-thick film, ... -
Liquid Exfoliated SnP<inf>3</inf> Nanosheets for Very High Areal Capacity Lithium-Ion Batteries
(2021)ncreasing the energy density of lithium‐ion batteries requires the discovery of new electrode materials capable of achieving very high areal capacity. Here, liquid phase exfoliation is used to produce nanosheets of SnP3, ... -
Liquid exfoliation of defect-free graphene
(2013)Due to its unprecedented physical properties, graphene has generated huge interest over the last 7 years. Graphene is generally fabricated in one of two ways: as very high quality sheets produced in limited quantities by ... -
