Effect of citrate concentration on colloidal gold (Au) nanoparticles produced using electro-dissolution-reduction method
Published 2016“…Throughout the process, bulk gold at the anode was oxidized into gold cations which then reacted with the chloride ions to form aurochloride complex. The complex ions were then reduced by the citrate ion to form colloidal gold nanoparticles. …”

Purification and characterization of surfactant-stable protease from Bacillus lichenformis: A potential additive for laundry detergent
Published 2016“…The enzyme was stable at temperature range of 35 oC to 65 oC and also at pH 6.0 and 7.0 for 60 min. The presence of Mn2+ and Ca2+ ions in the produced protease stimulated strongly the activity of the enzyme by 176.65% and 119.07% respectively, while inhibitory effects were found in the presence of Cu2+, Zn2+, Mg2+, and EDTA. …”

Two Potts Models on Cayley Tree of Arbitrary Order
Published 2012“…On a Cayley tree of arbitrary order k we consider two different Potts models with competing nearest-neighbour interactions J1 and next-nearest-neighbour interactions Jp and Jo, where coupling Jp corresponds to interaction of spins belonging to the same branch of the tree (prolonged) and coupling Jo corresponds to interaction of spins belonging to the same shell of the tree (one-level) and find for each model in addition to the expected paramagnetic, ferromagnetic and antiferromagnetic phases, an intermediate range of coupling values where the local magnetization has chaotic oscillatory glass-like behaviour. …”

Adsorption behavior of PB(II) onto xanthated rubber (Hevea brasiliensis) leaf powder
Published 2011“…A plant waste, rubber (Hevea brasiliensis) leaf powder was modified with carbon disulfide (xanthation) for the purpose of introducing sulfur groups, and the adsorbent performance in removing Pb(II) ion was evaluated. Pb(II) adsorption was confirmed by spectroscopic analysis, which involved Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). …”
