Zhang X., He J., Chan M., Du C., Ye Y., Zhao W., Wu W., Wang W., PKU-HKUST Shenzhen-Hongkong Institution, CN

A physics based potential model for intrinsic long-channel cylindrical surrounding gate MOSFETs with SiO2 -core Si-Shell structure is presented in this paper. The accurate potential solution of Poisson’s equation in a cylindrical coordinate system is [...]

Bioinspired Layered Materials with Superior Mechanical Performance Via Interface Design

Cheng Q., Jiang L., Tang Z., Beihang University, CN

After billions of years of evolution, the natural nacre, consisting of almost 95 vol% inorganic plates (aragonite calcium carbonate) and 5 vol% organic macromolecules (elastic biopolymer), shows a unique combination of the remarkable strength and [...]

Carriers Transport in Quantum Dot Quantum Well Microstructures of Self-assembled CdTe/CdS/ligand Core-shell System

Li K., Yanshan University, CN

The photo-generation carriers’ transport characteristics in CdTe quantum dots (QDs) capped by ligand were probed using a combination of surface photovoltaic (Figure 1) and photoacoustic techniques. The results confirmed that the QDs were composed of [...]

Versatile Polymer-Derived Nanocrystal Microreactors towards Uniform Fluorescent Photonic Crystal Supraballs

Zhang J., Ling L.T, Tian Y., Wang C.F., Chen S., Zhang J., Nanjing Tech University, CN

In this work, versatile polymer-derived NC microreactors were designed for the first time towards the construction of fluorescence colloidal photonic crystals. The carboxyl-terminated polystyrene colloids were synthesized by seeded copolymerization of AA and HEMA with [...]

Microstructures design of the assembly of monodisperse polystyrene microspheres via alternative current electric field

Ling L.T, Zhang J., Wang C.F., Chen S., Nanjing Tech University, CN

The assembly of monodisperse polystyrene microspheres under alternative current electric field was applied as a model system to study the assembling mechanism for nanomaterials. The microspheres of about 1-2 μm in diameter enable us to [...]

Bio-Inspired Multi-gradient Structure Surfaces for Water Collection/Repellency

Zheng Y., Beihang University, CN

Biological surfaces with micro- and nanostructures display unique wetting functions. Since spider silk collects water through a combination of multiple gradients in a periodic spindle-knot structure after wet-rebuilding process, a series of functional fibers with [...]

Monodisperse Thermo-responsive Composite Microgels with Core-shell Structure based on Au@Ag Bimetallic Nanorod as Core: Fabrication and Application in SERS Substrate

Dong X., Zha L.S., Donghua University, CN

In summary, monodisperse Au@Ag bimetallic nanorod is encapsulated by crosslinked poly(N-isopropylacrylamide) (PNIPAM) to produce thermo-responsive composite microgel with well-defined core-shell structure (Au@AgNR@PNIPAM microgel) by seed-precipitation polymerization method using butenoic acid modified Au@AgNRs as seeds. Their [...]

Toxicity and Pharmacokinetics of uPAR-targeted Human ATF-conjugated Iron Oxide Nanoparticles Following Systemic Delivery in Rhesus Monkey

Chen Y., Gao F., West China Hospital, Sichuan University, CN

Increasing evidence support the potential of a novel cell surface receptor-targeted MRI nanoprobe produced by conjugating a recombinant peptide amino-terminal fragment (ATF) of urokinase plasminogen activator (uPA) to magnetic iron oxide nanoparticles (IONP) in targeted [...]
