Abstract:
A silicon nanoparticle–graphite nanosheet composite was prepared via a facile ball milling process for use as the anode for high-rate lithium-ion batteries. The size effect of Si nanoparticles on the structure and on the lithium-ion battery performance of the composite is evaluated. SEM and TEM analyses show a structural alteration of the composites from Si nanoparticle-surrounded graphite nanosheets to Si nanoparticle-embedded graphite nanosheets by decreasing the size of Si nanoparticles from 250 nm to 40 nm. The composites with finer Si nanoparticles provide an effective nanostructure conta

Abstract:
Mechanical properties of natural rubber composite were improved by adding chitosan nanoparticles in this work. The chitosan nanoparticles were prepared by ionotropic gelation method. The effect of chitosan nanoparticle content in natural rubber at 0, 3, 6 and 9 phr were studied. Size of the synthesized chitosan nanoparticles was 282 ± 96 nm. Natural rubber vulcanization was by electron irradiation at intensity 200 kGy. The morphology of composite was investigated by scanning electron microscopy (SEM). The mechanical properties (tensile strength and modulus) were determined by tensile testing.

To attain the narrow bezel characteristic of information displays, functional sealing composite materials should possess high adhesion strength and water barrier performance due to their narrow line widths.

Abstract:
Abstract This research presents a novel approach for producing metal matrix composite powders using a nanoparticle decoration technique. A 1wt% stable suspension of 30nm Al2O3 particles was decorated onto primary AA6061using a redispersion method. The resulting AA6061-1wt% Al2O3 composite powder was mixed in a rotary mixer for one hour and subsequently dried at 45°C. Scanning electron microscopy of the composite powder confirmed the successful material composition. The composite powders were then deposited onto an AA6061 substrate using a low-pressure cold spray system, with the coating qualit

Abstract:
Abstract Hybrid composite stacks are multi-material laminates which find extensive applications in industries such as aerospace, automobile, and electronics. Most hybrid composites consist of multi-layer fiber composites, and metal sheets stacked together. These composite stacks have excellent physical and mechanical properties, including high strength, high hardness, high stiffness, excellent fatigue resistance, and low thermal expansion. Composite stacks are fabricated to near net shape; additional machining operations are often required for several applications, primarily in the aerospace i

Abstract:
Natural fibers are a lightweight, carbon negative alternative to synthetic reinforcing agents in polymer composites. However, natural fibers typically exhibit lower mechanical performance than glass fibers due to weak interfacial adhesion between plant cells in the fiber and damage to the fibers during extraction from a plant stem. However, improvement of natural fiber mechanical performance could enable their wide-scale incorporation in structural composite applications, significantly reducing composite weight and carbon footprint. This study seeks to develop a novel, cost-effective method to

Abstract:
Abstract Nanoparticle-included polymeric composite coatings with preferential nanoparticle alignment and oriented structures show improved functional and structural properties than randomly oriented structures, suitable for broad applications in microelectronics, automobile, defense, and space missions. Traditionally used techniques, such as drop-casting, chemically modified surfaces, and external fields, have been used for self-assembly but with several disadvantages, such as material limitations. Thus, there is a need to develop a new approach for generating hierarchical nanoparticle structu

Abstract:
The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the

Abstract:
Chair-side rapid detection of mutans streptococci is an important aid to clinical dental caries risk assessment. Rapid Streptococcus mutans detection tools are available on the market but there are a small number. Automutanolysin (Aml) is a peptidoglycan hydrolase whose cell wall-binding domain (CWBD) has substrate-specificity towards mutans streptococci. This study aims to develop a rapid detection assay using CWBD conjugated with horseradish peroxidase (HRP). However, the recombinant protein was as insoluble form. Therefore, magnetic nanoparticles were used as an alternative reporter to conj
