Molecular Modeling of Silicon-Based Anode Material for High-Performance Lithium-Ion Batteries

Schweizer S., Low J.J., Subramanian L., Scienomics, US

Lithium(Li)-ion batteries are widely used in portable electronic devices. Their use as energy storage system in other important industrial fields - such as electric vehicles, wind turbines, or photo voltaic plants - is limited by [...]

A nanocrystalline materials production technique for simultaneously improving several properties

Wang S.G., Institute of Metal Research, Chinese Academy of Sciences, CN

The concept of nanocrystalline metallic materials was put forward by Prof. Gleiter in 1980s [1]. From then on, nanocrystlline metallic materials have been extensively studied by the scientists all over the world [2]. The first [...]

Graphene oxide/vinyl ester resin nanocomposite: the effect of graphene oxide, curing kinetics, mechanical properties and thermal stability

Arabli V., Aghili A., Islamic Azad University, Shiraz, IR

Graphene oxide (GO) was synthesized and nanocomposite was achieved using different contents of the GO and Vinyl Ester Resin (VE). The suspension was sonicated in order to prevent the agglomeration. Non-isothermal differential scanning calorimetry (DSC) [...]

Preparation and mechanical properties of fiber-reinforced silica aerogels and its phase change nanocomposite

Zhou X., Georgia Institute of Technology, US

The present study is devoted to the investigation of mechanical properties of fiber-reinforced silica aerogels and composite phase change materials. We firstly reported our study on the preparation process of fiber-reinforced silica aerogels and PCM/silica [...]

Synthesizing and Consolidation of Mechanically-Induced Solid-State Reacted Ti50C50 Nanopowders and Subsequent Consolidations

Sherif El-Eskandarany M., Al-Hazza A., Shaban E., Alduweesh A., Al-Rowayeh A., Kuwait Institute for Scientific Research, KW

In contrast to the industrial approach for preparing such important materials, we have succeeded to synthesize a single phase of Ti50C50 nanopowders, using high-energy ball milling technique. The ball milling procedure took place at ambient [...]

Mechanical Properties of Reduced Graphene Polymer Composites

Xu P., Panchapakesan B., University of Louisville, US

In this paper, we report load transfer and mechanical properties of chemically derived single layer graphene (SLG) as reinforcements in poly (dimethyl) siloxane (PDMS) composites. Shear mixing reduced graphene sheets in polymers resulted in a [...]

Correlating electrical and structural properties in surface layer of carbon nanotube polymer composite

Pavlenko E., Tishkova V., Puech P., Bacsa W.S., CNRS and University of Toulouse, FR

We have recently shown that annealing of agglomerated carbon nanotubes on thermoplast polymers form surface composite films (70 micrometers) (1). This has been explained by preferential carbon nanotubes absorption of infrared radiation leading to local [...]

Novel Green Polymer Composites: Major Enhancements in the Crystallization Kinetics of Poly(lactic acid) and Mechanical Properties of Polypropylene Created via Solid-State Shear Pulverization

Brunner P.J., Torkelson J.M., Kane N., Northwestern University, US

Hybrids of polylactide (PLA) or polypropylene (PP) with microcrystalline cellulose (MCC) were created using a continuous, industrially scalable, and environmentally benign process called solid-state shear pulverization (SSSP). The PLA composite was subsequently melt-processed (MP) with [...]

A novel cyclic forward-backward extrusion process for production of ultrafine grains materials

Alihosseini H., Asle Zaeem M., Dehghani K., Mississippi State Univeristy, US

A new cyclic forward-backward extrusion (CFBE) process was introduced as a severe plastic deformation (SPD) technique to produce ultrafine-grained aluminum rods. According to transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD) results, the average [...]
