RISThe Effect of Cationic Charge Density Change on Transfection Efficiency of Polyethylenimine
Objective(s): Polyethylenimine (PEI) is a potent non-viral gene delivery carrier. PEI surface charge plays a major role in its condensation ability which in turn is a necessary requirement for high transfection efficiency. ...
Sono-catalytic degradation and fast mineralization of p-chlorophenol: La0.7Sr0.3MnO3 as a nano-magnetic green catalyst
La0.7Sr0.3MnO3 (LSMO) nanoparticles with a perovskite structure were prepared by a combination of
ultrasound and co-precipitation method. The synthesized catalyst was characterized by X-ray diffraction,
transmission ...
Influence of nanoparticles on reducing and enhancing evaporation mass transfer and its efficiency
that depending on the type of nanoparticle,
nanofluid evaporation can be decreased or increased. The results revealed that TiO2, ZrO2, Fe2O3 and Ni/Fe
nanoparticles are able to reduce their base fluid evaporation rate, but clay nanoparticle...
Synthesis, characterization, and measurement of structural, optical, and phtotoluminescent properties of zinc sulfide quantum dots
A facile and rapid microwave irradiation method was developed to prepare ZnS nano-particles (NPs) using a set of ionic liquids (ILs) based on the bis(trifluoromethylsulfonyl)
imide anion and different cations of ...
Effect of Substitutions of Zn for Mn on Size and Magnetic Properties of Mn–Zn Ferrite Nanoparticles
Abstract In this study Mn–Zn ferrite nanoparticles
(Mn(1−x)ZnxFe2O4, x = 0, 0.3 and 0.5) were produced by
a chemical co-precipitation method. The structure and size
of the Mn–Zn ferrite nanoparticles ...
X-ray analysis of ZnO nanoparticles by Williamson–Hall and size–strain plot methods
ZnOnanoparticles (ZnO-NPs) were prepared by a sol–gel combustion method from a zinc acetate precursor and acetic acid. The ZnO-NPs were synthesized at calcination temperatures of 650 °C and 750 °C for 1 h. The synthesized ...
An experimental investigation of ignition probability of diesel fuel droplets with metal oxide nanoparticles
The aim of this study is to investigate the effects of nanoparticles type, nanoparticles size, and droplet size on the
ignition probability of the diesel fuel. Also, the effect of metal oxide nanoparticles on the ...
The effect of preliminary mechanical activation on the zinc loss control in combustive reduction of MoO3 by Zn
Due to the high temperature at combustion moment, the combustive reduction of MoO3 by Zn is normally
accompanied with a great deal of zinc vaporization and the formation of undesired compound, Zn2Mo3O8.
Experimental ...
Experimental and numerical investigation on hydrothermal performance of nanofluids in micro-tubes
Nanoscale solid particles suspended in a base liquid are a new class of nano-engineered colloidal suspension, defined with a coined name of nanofluids (NFs). The effect of dispersing nanoparticles (NPs) on the hydraulic ...
Dynamic swarm learning for nanoparticles to control drug release function using RBF networks in atherosclerosis
Nanomedicine is an interdisciplinary research area that aims at prevention, diagnosis and treatment of complex diseases by the nanoscale operators to reduce side effects and increase the cure rate. Simplicity and limited ...
