The effect of Fe and Ni catalysts on the growth of multiwalled carbon nanotubes using chemical vapor deposition [PDF]
Journal of Nanoparticle Research, (2010), Vol. 12, pp. 457- 465, 2019 The effect of Fe and Ni catalysts on the synthesis of carbon nanotubes (CNTs) using atmospheric pressure chemical vapor deposition (APCVD) was investigated. Field emission scanning electron microscopy (FESEM) analysis suggests that the samples grow through a tip growth mechanism.

Carbon riveted Pt/MnO2-Graphene catalyst prepared by in situ carbonized L-ascorbic acid with improved electrocatalytic activity and stability [PDF]
arXiv, 2020 Pt/Graphene and Pt/MnO2-Graphene catalysts have been prepared by microwave-assisted polyol process. Electrochemical results show that Pt/MnO2-Graphene has higher electrocatalytic activity and stability. Furthermore, carbon riveted Pt/MnO2-Graphene catalyst has been designed and synthesized on the basis of in situ carbonization of L-ascorbic acid.

Generation of Nano-Catalyst Particles by Spinodal Nano-Decomposition in Perovskite [PDF]
, 2008 A new mechanism of nano-catalyst generation based on the spinodal nano-decomposition in self-regenerating perovskite catalysts for automotive-emissions control is proposed. To demonstrate existence of the spinodal nano-decomposition in real perovskite catalysts, we performed first-principles calculations to evaluate the free energy of La(Fe$_{1-x}$Pd ...

MaHKUscript: Journal of Fine Art Research, 2020 The socio-ecological challenges of recent times questioned the roles and responsibilities of artists and cultural practitioners. Several artists approached current issues by imagining new ways of living for a more sustainable form of future, attempting to trigger social transformation, a shift in values, changes in environmental issues, or a crucial ...

Growth and Characterization of Multi-Walled Carbon Nanotubes using Chemical Vapor Deposition [PDF]
arXiv, 2018 In this study, the synthesis of multi-walled carbon nanotubes (MWCNTs) was carried out by chemical vapor deposition (CVD) using propane as the carbon source and Si as the catalyst support. The effect of CVD process variables such as temperature, choice of catalyst, etc on the growth behavior of nanotubes has been examined to understand the catalytic ...

Copper Replaces Tin: A Copper based Gelling Catalyst for Poly-Urethane from Discarded Motherboard [PDF]
arXiv, 2013 A discarded motherboard based eco-friendly copper catalyst has been programmed to replace the industrially used tin based catalyst DBTDL. The catalyst has been characterized by UV-Vis spectroscopy, FT-IR and TEM. Using the catalyst reaction conditions is optimized and under the optimized condition, both polyurethane and polyurethane foam are prepared ...
