1D Multi-Structured Micro/nanomaterials with Special Wettability

Zhao Y., Beihang University, CN

With the progresses in material sciences, the generation of microscopic materials experiences an architectural evolution process from simple to complex. The complex interior structures will enable such materials a number of potential applications. Here we [...]

An explosive impact technique to nanocrystallize and harden surface of metal materials

Tong S.J., Tong Z., Shi Z.M., Tong S.J., Tong Z., Inner Mongoli University of Technology, CN

An explosive impact surface nanorisation technique (EISNT) was developed to prepare nanostructured surface layers on medium carbon steel (MCS) and pure Copper (PC) plates. The plastic deformation involved the entire plate depth of 4-6 mm, [...]

Nano Graphene Oxide as Drug Carrier for Antihypertensive Agent: Benazepril, Captopril and Losartan

Wang J., Long Y., Tao C., Liu H., Zhu H., Zhou X., National University of Defense Technology, CN

Graphene oxide (GO) offers large surface and novel biocompatible properties that are currently being explored for advanced drug carriers. GO has a one-atom-thick two dimensional carbon system, which contains several kinds of oxygen functional groups [...]

Graphene/PDMS composites for optical heating on microfluidic chips

Tao C., Lv Y., Liu H., Hu Z., Zhu H., Wang J., National University of Defense Technology, CN

Microfluidic chips have attracted extensive attention from both industrial and academic communities due to its virtues of miniaturization, integration, automation. Nowadays, simple and economical means of photothermal conversion on microfluidic chips are strongly desired.In this [...]

Ultratough Artificial Nacre Based on Conjugated Cross-linked Graphene Oxide

Cheng Q., Beihang University, CN

In this work, inspired by the relationship of excellent toughness and hierarchical nano-/micro-scale structure of natural nacre, we developed a novel strategy for fabricating the integration of ultratough and high strength artificial nacre based on [...]

Preparation and near infrared emission research of YBO3:Ce3+,Yb3+ nanosheets

Wang Y., Hu X., Zhan S., Zhang D., Zhang D., Fan J., Northwest University, CN

Y0.97Ce0.01Yb0.02BO3 nanosheets(a) and micro-rose(b) have the same hexagonal structure, and the intensity of (110) and (100) diffraction peaks of the sample a is stronger than b. Annealing the sample b in different temperature, the higher [...]

Polarization insensitive and wide-angle plasmonically induced transparency by planar metamaterial

Chen S., Cheng H., Duan X., Yang H., Cheng H., Li J., Liu W., Liu W., Gu C., Tian J., Nankai University, CN

We present the design, characterization and experimental demonstration of a polarization insensitive and wide-angle plasmonically induced transparency (PIT) planar metamaterial (MM) in the near infrared regime. A four-level plasmonic model is proposed to explain and [...]

Field-Based 3D Capacitance Modeling for sub-45-nm On-Chip Interconnect

Zhang A., Zhao W., Ye Y., He J., Chen A., Chan M., Beijing University of Aeronautics and Astronautics, CN

Considering both two-dimensional and three-dimensional single wire above plate, the proposed method decomposes the electric field into various regions and gives solutions for each part. The total ground capacitance is the summation of all components. [...]

A Charge Based Non-Quasi-Static Transient Model for SOI MOSFETs
