Spherically symmetric oxidation model of aluminum nanoparticles

Ramazanova Z., Zyskin M., Martirosyan K.S., University of Texas at Brownsville, US

Kinetics of oxidation of metal nanoparticles acquired practical importance with rapidly developing nanoenergetic systems and materials. Nanoenergetic thermites include mixtures of Al and metal oxides in nanoscale. Our research focuses on modeling aluminum combustion in [...]

Direct observation of silver nanoparticle-ubiquitin corona formation

Ding F., Clemson University, US

The advancement of nanomedicine and the increasing applications of nanoparticles in consumer products have led to administered biological exposure and unintentional environmental accumulation of nanoparticles, causing concerns over the biocompatibility and sustainability of nanotechnology. Upon [...]

Computational Hierarchy Modeling of Self-assembled Polyurea Aerogels

Chen G.D., Missouri University of Science and Technology, US

An economical environmentally friendlier synthesis of nanoporous polyurea aerogels from triisocuyanates and water has recently been described. Owing to their multi-functionality and superior mechanical properties, those materials are finding their way into various engineering applications. [...]

Surface Structure of the drug delivery liposome

Magarkar A., University of Helsinki, FI

The criteria for effectiveness of drug delivery liposomes (DDLs) are structural stability, site specific targeting, and lifetime in the bloodstream. Often to increase the lifetime in bloodstream DDL is coated with poly ethylene glycol (PEG). [...]

Hot Phonons Contribution to scattering rates in Single-Walled Carbon Nanotubes

Gautreau P., Ragab T., Basaran C., University of Tabuk, SA

The influence of hot phonons on the electron-phonon scattering rates is studied via an Ensemble Monte Carlo(EMC) simulation with step by step update of the phonon occupation number to account for the generation of hot [...]

Simulation of water adsorption on a diamond (100) surface containing a vacancy defect

Lvova N.A., Lvova N.А., Ananina O.Yu., Lvova N.A., Lvova N.А., Federal State Bugetary Institution, RU

Water is one of the most important adsorbates interacting with the diamond surface. In particular, the presence of -H and -OH on the surface affects the physical and chemical properties of nanocrystalline diamond particles, which [...]

Effect of Roughness on Wettability of a Surface by Nano-droplets: Correlation With the Slip Length in Nanofluidics

Jabbarzadeh A., The University of Sydney, AU

Surface characteristic govern friction, flow, wettability and many other properties in solid-liquid interfaces. Wettability of surfaces is usually determined by measuring the contact angle of a single droplet put on the surface. Liquid repelling surfaces [...]

GIDL Current and Pass-Gate Body Potential Modeling in 22nm HKMG PD-SOI CMOS

Luo L., Walko J.P., Johnson J.M., Springer S., IBM, US

In a floating PD (partially depleted) SOI (silicon-on-insulator) transistor, the internal DC body potential is determined by the various body current components, mainly including diode current, gate-to-body oxide tunneling current (Igb), impact ionization current (II) [...]

Compact Modeling of Parameter Variations of Nanoscale CMOS due to Random Dopant Fluctuation

Ye Y., Zhu Y., He H., He J., Mei J., Cao Y., He H., He J., PKU-HKUST Shenzhen-Hongkong Institution, CN

In nanoscale CMOS design, the compact modeling of random dopant fluctuation (RDF), which is the major variability source, is crucial important to bridge the variation aware design to the underlying physics. In this paper the [...]

An Efficient and Accurate Schematic Transistor Model of FinFET Parasitic Elements

Lu N., Hook T.B., Johnson J.B., Wermer C., Putnam C., Wachnik R.A., IBM, US

We present a schematic transistor model for multi-finger multi-fin FETs, which reduces an initial complex finFET network to a very simple finFET network. The schematic finFET model is accurate in predicting overall finFET characteristics, including [...]
