Submitted for the MAR14 Meeting of The American Physical Society Chirally Selective Growth of Single Walled Carbon Nanotube on Fe13 Nanocatalyst 1 ANTENEH TEFERA, MOGUS MOCHENA, Florida A&M University — Controlled growth of single walled carbon nanotubes with desired chiral indices remains the holy grail of single walled carbon nanotube synthesis. We performed ab initio molecular dynamics calcu...

Metaldehyde, an organic pesticide widely used in the UK, has been detected in drinking water in the UK with a low concentration (<1 μg L-1) which is still above the European and UK standard requirements. This paper investigates the efficiency of four materials: powdered activated carbon (PAC) and carbon-doped titanium dioxide nanocatalyst with different concentrations of carbon (C-1.5, C-40, an...

Inorganic nano-graphene hybrid materials that are strongly coupled via chemical bonding usually present superior electrochemical performance. However, how the chemical bond forms and the synergistic catalytic mechanism remain fundamental questions. In this study, the chemical bonding of the MoS2 nanolayer supported on vacancy mediated graphene and the hydrogen evolution reaction of this nanocat...

The food waste management has become a very important part in the modern world. In olden days, population was low, so that low produced easily disposed by dumping it under soil. However, nowadays, due to high population, amount of is which could not be dumped land pollution. To overcome this problem, must managed or utilized properly give zero waste. Therefore, work focused on production biogas...

the dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. cu and ni unites nanocatalyst powders sithcomposition of caned], and nife204 were synthesized by a sol-gel auto catalnic combustion process. themolar ratio between metal ions and urea was 11.2. the sob gel process was done at 8...

The focus of this research lies on fundamental research to provide guidelines for the design of new nanocatalyst toward improvement of the performance of proton exchange membrane fuel cells (PEMFCs). To achieve this overarching goal, several specific steps were taken with aims to: (1) provide guidelines for the design of new catalysts; (2) promote nanocatalyst applications towards alternative e...

Bimetallic nanoparticles have attracted significant attention as their electrochemical and catalytic properties being superior to those of the individual component nanoparticles. In this study, gold-silver hybrid nanoparticles (AuAgNPs) with an Aucore-Agshell nanostructure were successfully synthesized on zinc oxide (ZnO) whiskers. The as-prepared nanocatalyst, denoted AuAgNPsZnO whisker, exhib...

SOFCs running on jet fuel reformates are attractive to NASA for its uninhabited aerial vehicle and low emission alternative power missions. The US military has interest in fuel cells due to their lightweight, zero emission and low acoustic signatures in strategic zones. Jet fuels, such as Jet-A and JP-8 are already on board in many applications. If they can be reformed and used in fuel cells, m...

The most common approach in the search for the optimal low temperature fuel cell catalyst remains "trial and error". Therefore, large numbers of different potential catalytic materials need to be screened. The well-established and most commonly used method for testing catalytic electrochemical activity under well-defined hydrodynamics is still thin film rotating disc electrode (TF-RDE). Typical...

In this work, copper(II) heterogeneous nanocatalyst supported on modified AlPO4 (Cu(II)-DA@Nano AlPO4) was used for the synthesis of some biological active heterocyclic molecules, particularly for the efficient conversion of a wide range of non-activated terminal alkynes to β-hydroxy 1,4-disubstituted 1,2,3-triazolethrough a three-component “click” reaction at room temperature in water. The reg...
