They have also reported a method of controlling the chemical reactivity of contact explosives by exploiting weak interactions or soft force during amide bond synthesis under ball-milling conditions. Cross dehydrogenative coupling reactions between benzaldehydes and benzylamines were performed in presence of phenyliodine diacetate (PIDA) using the acid salt NaHSO 4 [81] .


In Situ synthesis of SiC

A wet ball milling route was used to synthesise SiC-graphene core-shell nanoparticles in situ from graphite and SiC nanoparticles. Graphite flakes were gradually exfoliated into fresh graphene nanosheets (GNSs) without significant defects, which is attributed to mechanical shearing and moderate impaction forces between graphite flakes, milling balls and SiC nanoparticles during the wet milling.

Abstract A rapid method for synthesizing β-silicon carbide (β-SiC) fine fiber composite has been achieved by combining forcespinning technology with microwave energy processing.β-SiC has applications as composite reinforcements, refractory filtration systems, and other high temperature applications given their properties such as low density, oxidation resistance, thermal stability, and

2012/11/25Even if the attritor synthesis process of SiC decreases the mean particle size of the SiC down to about 70 nm, a number of micro-scale particles are still present in the final composite. The nanoparticles have a more regular shape and the amount of nano-SiC particles is increased in Al/10SiC compared to Al/5SiC, Fig. 5 (b) and (c).

have only been limited studies of synthesis of silicon carbide fibers from polycarbosilane by electrospinning method. Moreover, there is no previous report for tensile strength testing of SiC fibers synthesized by electrospinning. The main objectives of this

Silicon Carbide in Microsystem Technology — Thin Film

2014/11/10This process allowed the synthesis of SiC with suitable quality for use in electronic devices, which was not possible using the previous method demonstrated by Acheson in 1892. One limitation of the Lely method is the growth of small SiC substrates only up to 10 mm in diameter.

We succeeded in the synthesis of single-phase β-SiC nanoparticles via simple and low-cost high-energy mechanical ball milling of a silicon and graphite mixture at ambient temperature. The synthesis products were characterized by X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM) and selected area electron diffraction (SAED).

In this work, synthesising of SiC nanoparticles by mechanical milling was studied. The influence of ball to powder ratios, milling speeds and milling times in three levels on the specific surface area of SiC particles using central composite design was investigated. The

The mechanochemical synthesis of functionalized silicon nanoparticles using High Energy Ball Milling (HEBM) is described. This method facilitates the fragmentation of mono crystalline silicon into the nanometer regime and the simultaneous surface functionalization of the formed particles.

Processing and Synthesis of Nanomaterials It is classified as bottom-up manufacturing which involves building up of the atom or molecular constituents as against the top method which involves making smaller and smaller structures through etching from the

Processing SiC/SiC composites are mainly processed through three different methods. However, these processing methods are often subjected to variations in order to create the desired structure or property: Chemical Vapor Infiltration (CVI) – The CVI method uses a gas phase SiC precursor to first grow SiC whiskers or nanowires in a preform, using conventional techniques developed with CVD.
