RISFacile synthesis of copper oxide nanoparticles using copper hydroxide by m echanochemical process
Abstract
A facile mechanochemical -based method for synthesis of copper oxide (CuO) nanoparticles is here by introduced . For this purpose, copper hydroxide powder was synthesized through a facile solution
method (CuSO4+ 2...
A new approach for reclaiming of waste automotive EPDM rubber using waste oil
The disposal of polymeric and especially rubber materials is an important global issue. In this work we have used disulfide oil (DSO), the oily waste produced in gas refineries, as a chemical agent for mechanochemical reclaiming of waste EPDM rubber...
Conversion of W2C to WC phase during mechano-chemical synthesis of nano-size WC–Al2O3 powder using WO3–2Al–(1+x)C mixtures
Due to the weak properties of W2C phase, its formation during the process of WC synthesis should be
prevented. The aim of the present study has been the mechano-chemical synthesis of aWC–Al2O3 composite powder free from undesirable W2C phase...
Nanocrystalline Growth Activation Energy of Zirconia Polymorphs Synthesized by Mechanochemical Technique
A novel method for fabrication of Fe catalyst used for the synthesis of carbon nanotubes
Carbon nanotubes (CNTs) have been grown by decomposition of propane over a nanocamposite
catalyst by chemical vapour deposition (CVD). The catalyst was prepared from an aluminum/iron
oxide/graphite mixture ...
Synthesis of mullite–MoSi2 nano-composite through a mechanochemical processing
Nano-composite mullite–MoSi2 with 40 wt.% MoSi2 was produced from the raw materials of MoO3, Al and Si by mechanochemical processing. Different Al amounts (stoichiometric amounts of 1, 1.5 and 2 mol) and milling times (15, 23, 30, 60, 180, 300 min...
Mechanochemical leaching of chalcopyrite concentrate by sulfuric acid
This study aimed to introduce a new cost-effective methodology for increasing the leaching efficiency of chalcopyrite concentrates at ambient temperature and pressure. Mechanical activation was employed during the leaching (mechanochemical leaching...
Mechanism of nanostructured florapatite formation from CaO, CaF2 and P2O5 precursors by mechanochemical synthesis
We determined the mechanism of mechanochemical synthesis of florapatite from CaO,
CaF2 and P2O5 by characterisation of the intermediate compounds. We used atomic
absorption spectroscopy, X-ray diffraction, fild emission scanning...
Mechanochemical reaction of Al and melamine: a potential approach towards the in situ synthesis of aluminum nitride–carbon nanotube nanocomposites
In the current study, an inexpensive solid-state mechanochemical technique is proposed for the in situ
synthesis of nanostructured aluminum nitride (AlN) and carbon nanotubes (CNTs). The CNTs and
nitrogen-doped CNTs are synthesized through a...
Mechanical fabrication of AlN-C nano-composite through ball-milling of Al and melamine
A novel mechanochemical process is proposed for facile synthesis of aluminium nitride-carbon (AlN-C) nanocomposite via ball-milling of melamine (C3H6N6) and aluminum powders. Melamine was implemented, as source of nitrogen of Ali particles...
