Nanopowder net-shaping for manufacturing nanostructured ceramics

Khasanov O.L., Dvilis E.S., Sokolov V.M., Pokholkov Yu., Loutts G., Tomsk Polytechnic University, RU

The work aim is development of methods of dry nanopowder uniform compacting into complex shapes for sintering nanostructured ceramics and composites. In processing of bulk nanoceramic articles, it is important to compact nanopowder into a [...]

Polymer coated Carbon Nanotube probes for Scanning Electrochemical Microscopy

Patil A.V., Vlijm R., Oosterkamp T., Leiden Institute of Physics, NL

We demonstrate a method for fabrication of a Scanning ElectrochemicalMicroscopy (SECM) probe using a parylene coated Carbon Nanotube as a nanoscaleelectrode. Parylene is used to achieve a conformal pinhole free insulatinglayer, which is a major [...]

TiO2/CNT coaxial composite array with visible-light absorption

Chang C-C, Chen C.C., National Chung Cheng University, TW

TiO2, CNT, coaxial composite array, visible-light absorption

First-principle Study for Neutral Indium Migration in Silicon

Yoon K-S, Won T., Inha University, KR

We could figure out the atomistic configurations and migration energy during indium diffusion in silicon through our ab-initio calculations, which consists of searching for saddle points from a minimum and reaction pathway between the two [...]

Revealing of a Particular Physical Mechanism of Disordered Photocatalytic Structure Functioning

Evstratov A., Chis C., Taulemesse J.-M., Gaudon P., Peirano F., Ales Hihg Mining School, FR

Both reduction and oxidation products are simultaneously formed at the surface of the crystalline (“classic”) photocatalysts. As to probable photocatalytic properties of disordered structures, their functioning could be provided by a reinforced artificial separation of [...]

Novel Function of the Boron Icosahedron; a New Mediator of Magnetic Interaction

Mori T., National Institute for Materials Science, JP

Rare earth borides containing the B12 icosahedron display surprisingly strong magnetic interactions although they are magnetically dilute insulating materials with localized f-electrons. A microscopic local probe, ESR, was utilized to investigate the mechanism of the [...]

Active Coatings Technologies for Customized Military Coating Systems

Zunino III J.L., U.S. Army ARDEC, US

The main objective of the U.S. Army’s Active Coatings Technologies Program is to develop technologies that can be used in combination to tailor coatings for utilization on Army Materiel. The Active Coatings Technologies Program, ACT, [...]

A History of MOS Transistor Compact Modeling

Sah C-T, University of Florida, US

The MOSFET (Metal-Oxide-Silicon Field-Effect- Transistor) or MOS Transistor (MOST) is a three dimensional electronic device. It operates on the conductivity modulation principle in a thin semiconductor layer by a controlling electric field to give amplifying [...]

Vector Potential Equivalent Circuit for Efficient Modeling of Interconnect Inductance

Pacelli A., SUNY-Stony Brook, US

We present a compact topology for inductive parasitics, using the vector potential as a state variable. The model is local, i.e., only coupling between neighboring wires is explicitly modeled. However, the topology accounts for long-range [...]

Compact Modeling for RF and Microwave Integrated Circuits

Niknejad A.M., Chan M., Hu C., Brodersen B., Xi J., He J., Emami S., Doan C., Cao Y., Su P., Wan H., Dunga M., Lin C.H., University of California at Berkeley, US

Compact modeling has been an integral part of the design of integrated circuits for digital and analog applications. The availability of scalable CMOS device models has enabled rapid simulation and design of present and future [...]
