The integration of gallium nitride(GaN)nanowire light-emitting diodes(nanoLEDs)on flexible substrates offers opportunities for applications beyond rigid solid-state lighting(e.g.,for wearable optoelectronics and bendable inorganic displays).Here,we report on a fast physical transfer route based on femtosecond laser lift-off(fs-LLO)to realize wafer-scale top–down GaN nanoLED arrays on unconventional *** with photolithography and hybrid etching processes,we successfully transferred GaN blue nanoLEDs from a full two-inch sapphire substrate onto a flexible copper(Cu)foil with a high nanowire density(~107 wires/cm2),transfer yield(~99.5%),and *** nanoanalytical measurements were conducted to evaluate the performance and limitations of the fs-LLO technique as well as to gain insights into physical material properties such as strain relaxation and assess the maturity of the transfer *** work could enable the easy recycling of native growth substrates and inspire the development of large-scale hybrid GaN nanowire optoelectronic devices by solely employing standard epitaxial LED wafers(i.e.,customized LED wafers with additional embedded sacrificial materials and a complicated growth process are not required).

Quantitative measurement of the mechanical properties of human antibodies with sub-lO-nm resolution in a liquid environment

引用

Nano Research 2015年第6期8卷 1987-1996页

作者： Agnieszka voss Center of Smart Interfaces Technische Universitot Darmstadt Alarich-Weiss-Str 10 64287 Darmstadt Germany Physics of Surfaces Institute of Materials Science Technische Universit~t Darmstadt Alarich-Weiss-Str. 16 64287 Darmstadt Germany

The nanomechanical properties of single human immunoglobulin G and M antibodies were measured in a liquid environment using a fast force-volume technique with sub-10-nm spatial resolution. The ultrastructural details of these molecules were resolved in the images. Simultaneously, important physical properties, including elasticity, adhesion, and deformation were measured. The dimensions and adsorption of the immunoglobulin M antibodies onto the substrate indicated that they are highly by a low elastic stiffness （34 ± 10 MPa） flexible. The antibodies were characterized and high deformability （1.5 ± 0.5 nm）.

Analysis and Efficient Solution of Stationary Schrodinger Equation Governing Electronic States of Quantum Dots and Rings in Magnetic Field

作者： Marta M.Betcke Heinrich voss Department of Computer Science University College LondonGower StreetLondon WC1E 6BTUK Institute of Numerical Simulation Hamburg University of TechnologyD-21071 HamburgGermany

In this work the one-band effective Hamiltonian governing the electronic states of a quantum dot/ring in a homogenous magnetic field is used to derive a pair/quadruple of nonlinear eigenvalue problems corresponding to different spin orientations and in case of rotational symmetry additionally to quantum number±ℓ.We show,that each of those pair/quadruple of nonlinear problems allows for the minmax characterization of its eigenvalues under certain conditions,which are satisfied for our examples and the common InAs/GaAs *** the minmax property we devise efficient iterative projection methods simultaneously handling the pair/quadruple of nonlinear problems and thereby saving up to 40%of the computational time as compared to the nonlinear Arnoldi method applied to each of the problems separately.

Cortico-centric effects of general anesthetics on cerebrocortical evoked potentials

引用

Neuroscience Bulletin 2015年第6期31卷 697-704页

作者： Logan J.voss James W.Sleigh Anaesthesia Department Waikato District Health Board University of Auckland Waikato Clinical School

Despite their ubiquitous use for rendering patients unconscious for surgery, our understanding of how general anesthetics cause hypnosis remains rudimentary at best. Recent years have seen increased interest in ＂top-down＂ cortico-centric theories of anesthetic action. The aim of this study was to explore this by investigating direct cortical effects of anesthetics on cerebrocortical evoked potentials in isolated mouse brain slices. Evoked potentials were elicited in cortical layer IV by electrical stimulation of the underlying white matter. The effects of three anesthetics （ketamine, etomidate, and isoflurane） on the amplitude, latency, and slope of short-latency evoked potentials were quantified. The N2/P3/N4 potentials - which represent the early cortical response - were enhanced by etomidate （increased P3-N4 slope, P 〈0.01）, maintained by ketamine, and reduced by isoflurane （lower N2/P3 amplitude, P 〈0.01）. These effects closely resemble those seen in vivo for the same drugs and point to a cortical mechanism independent of effects on subcortical structures such as the thalamus.
