Growth and Fabrication of High‐Quality Single Nanowire Devices with Radial p‐i‐n Junctions

Yunyan Zhang, Ana M. Sanchez, Martin Aagesen, Suguo Huo, more

Small > 15 > 3 > n/a - n/a

Nanowires (NWs) with radial p‐i‐n junction have advantages, such as large junction area and small influence from the surface states, which can lead to highly efficient material use and good device quantum efficiency. However, it is difficult to make high‐quality core–shell NW devices, especially single NW devices. Here, the key factors during the growth and fabrication process that influence the quality...

Phase Transitions in Confinements: Controlling Solid to Fluid Transitions of Xenon Atoms in an On‐Surface Network

Aisha Ahsan, S. Fatemeh Mousavi, Thomas Nijs, Sylwia Nowakowska, more

Small > 15 > 3 > n/a - n/a

This study reports on “phase” transitions of Xe condensates in on‐surface confinements induced by temperature changes and local probe excitation. The pores of a metal‐organic network occupied with 1 up to 9 Xe atoms are investigated in their propensity to undergo “condensed solid” to “confined fluid” transitions. Different transition temperatures are identified, which depend on the number of Xe atoms...

Improving the Sensitivity of Fluorescence‐Based Immunoassays by Photobleaching the Autofluorescence of Magnetic Beads

Shira Roth, Orr Hadass, Meir Cohen, Jasenka Verbarg, more

Small > 15 > 3 > n/a - n/a

In fluorescence‐based assays, usually a target molecule is captured using a probe conjugated to a capture surface, and then detected using a second fluorescently labeled probe. One of the most common capture surfaces is a magnetic bead. However, magnetic beads exhibit strong autofluorescence, which often overlaps with the emission of the reporter fluorescent dyes and limits the analytical performance...

Research advancements in the neurological presentation of flaviviruses

Tingting Chen, Xiaoen He, Peiru Zhang, Yawen Yuan, more

Reviews in Medical Virology > 29 > 1 > n/a - n/a

Owing to the large‐scale epidemic of Zika virus disease and its association with microcephaly, properties that allow flaviviruses to cause nervous system diseases are an important area of investigation. At present, although potential pathogenic mechanisms of flaviviruses in the nervous system have been examined, they have not been completely elucidated. In this paper, we review the possible mechanisms...

Haiyang Yao, Xueting Li, Xiaodi Shi, Gao Qiu, more

Polymers for Advanced Technologies > 30 > 2 > 312 - 319

In this paper, temperature and pH‐sensitive interpenetrating polymer network (IPN) nanogels (NGs) were firstly prepared, and magnetic hybrid NGs were made through in‐situ precipitation of Fe²⁺ and Fe³⁺ into the IPN NGs. Under the optimized condition, the resulting hybrid NG dispersion with up to 17.3 wt% magnetite was stable, while the size distribution of the NGs is broad due to the formation of...

Sneha Rathi, Raju Saka, Abraham J. Domb, Wahid Khan

Polymers for Advanced Technologies > 30 > 2 > 217 - 234

Bioadhesives and glues are widely used as an adjunct to conventional methods employed in healing the post‐surgical injuries and restoration of normal tissue functions. Protein‐based bioadhesives have been used for a long time, and they are a more biocompatible alternative compared with synthetic adhesives. They offer advantages such as ease of application, reduction in surgery time, improved quality...

Me₃SiBr/InCl₃ catalyzed allylation of alcohols: Identifying the combined Lewis structure and investigating the reaction mechanism

Changmei Liu, Shenglong Sang, Fei Chen, Yan Yan, more

Journal of Physical Organic Chemistry > 32 > 2 > n/a - n/a

The combined Lewis acid Me₃SiBr/InCl₃ shows unique performance in multireactions. The topology and catalytic properties of Me₃SiBr/InCl₃ were investigated by DFT method for clarifying the nature of chemical bonds and interactions. Quantum theory of atoms in molecules (QTAIM) analysis showed that the interaction between Me₃Si‐halide and In‐trihalide mainly belongs to the closed‐shell interaction. Natural...

Quantification of propagating and standing surface acoustic waves by stroboscopic X‐ray photoemission electron microscopy

Michael Foerster, Nahuel Statuto, Blai Casals, Alberto Hernández-Mínguez, more

Journal of Synchrotron Radiation > 26 > 1 > 184 - 193

The quantification of surface acoustic waves (SAWs) in LiNbO₃ piezoelectric crystals by stroboscopic X‐ray photoemission electron microscopy (XPEEM), with a temporal smearing below 80 ps and a spatial resolution below 100 nm, is reported. The contrast mechanism is the varying piezoelectric surface potential associated with the SAW phase. Thus, kinetic energy spectra of photoemitted secondary electrons...

Wound dressing, which can release anti‐infectives in a controlled way, is taking an important role in the treatment and recovery of the open wound. An adequate release of antibiotics can prevent infections from microorganisms effectively. Among the new candidates of fabricating base materials for wound dressing, electrospinning fiber mats are attracting numerous attentions for their excellent performance...
