Red Blood Cells as Endogenous Biotweezers for Optical Micromanipulation In Vivo

open access: yesAdvanced Science, EarlyView.
By synergistically integrating the long‐distance manipulation fiber probe (LDMFP) and endogenous red blood cells (RBCs) as biocompatible optical elements, a natural RBC biotweezer was developed for the desired microparticle manipulation and immune cell activation within living vasculature, which might offer an alternative tool for intravital optical ...

Disturbances of surface wave field due to wave scattering at shallow cavities

open access: yesYantu gongcheng xuebao, 2018
In homogenous half spaces, the wave fields at shallow depth are dominated by Rayleigh waves activated by the surface sources. When the forward Rayleigh waves encounter a shallow cavity, the displacement shapes and the particle orbit are changed. Rayleigh

Sticker Valence Governs Chain Collapse and Liquid‐Liquid Phase Separation in Peptide‐Inspired Associative Polymers

open access: yesAdvanced Science, EarlyView.
Peptide‐inspired associative polymers with arginine‐like guanidinium stickers and lysine‐like ammonium spacers undergo chain collapse and liquid‐liquid phase separation induced by reversible sticker associations. Sticker valence and tunable association strength jointly control the phase behavior, chain conformation, and interfacial cohesion of these ...

Moonlit sky polarization patterns from Cerro Paranal

open access: yesAstronomy & Astrophysics
We investigated the polarization patterns from the moonlit sky as observed from the European Southern Observatory at Cerro Paranal. The moonlit sky background can be significant in astronomical observations and thus be a source of contamination in ...

Terahertz Channel Modeling, Estimation and Localization in RIS‐Assisted Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Reconfigurable intelligent surfaces have become a recent intensive research focus. Based on practical applications, channel strategies for RIS‐assisted terahertz wireless communication systems are categorized into three different types: channel modeling, channel estimation, and channel localization.

Spontaneous Rayleigh-Brillouin scattering spectral analysis based on the Wiener filter

open access: yesAIP Advances, 2018
In this paper, a spontaneous Rayleigh-Brillouin scattering spectrometer is developed to measure the gaseous spontaneous Rayleigh-Brillouin scattering profiles over the pressure range from 1 to 5 atm for a wavelength of 532nm at a constant room ...

Twisted MoS2 Bilayers as Functional Elements in Memtransistors: Hysteresis, Optical Signatures, and Photocurrent Kinetics

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...

Probing methane in Uranus’ upper stratosphere using HST observations of the 1280 Å Raman feature

open access: yesAstronomy & Astrophysics
We analysed far-ultraviolet (FUV) spectra of Uranus obtained by the HST STIS and COS instruments in 2012 and 2014, respectively, to determine the brightness of Raman-scattered Lyman-alpha (Lyα) emissions centred at 1280 Å (hereafter, the Raman feature ...
