Characterization of Individual Nanoparticles and Applications of Nanoparticles in Mass Spectrometry (2011-08-08)The chemical characterization of individual nanoparticles (NPs) </= 100 nm in diameter is one of the current frontiers in analytical chemistry. We present here, a methodology for the characterization of individual NPs by ...
-
(2021-12-07)A zeolitic Imidazolate Framework-8 (ZIF-8) is a metal-organic framework (MOF) with good drug delivery capability. This study synthesized and characterized ZIF-8 nanoparticles encapsulated with trans-cinnamaldehyde oil (TC) ...
-
(2011-08-08)The Department of Energy funded a project to determine if the specific heat of thermal energy storage materials could be improved by adding nanoparticles. The standard thermal energy storage materials are molten salts. The ...
-
(2018-05-22)Arsenic (As) is a toxic element widely encountered in the environment and a food safety concern. The use of engineered nanoparticles (ENPs) has grown rapidly due to the unique properties that make them beneficial in a wide ...
-
(2013-11-26)In-situ oil-in-water emulsion generation, using modified silica hydrophilic nanoparticles as emulsifier, has been proposed as an enhanced oil recovery process. The nanoparticles are injected as an aqueous dispersion; its ...
-
(2011-08-08)This study presents the results of nano-particle and surfactant-stabilized solvent-based emulsion core flooding studies under laboratory conditions that investigate the recovery mechanisms of chemical flooding in a heavy ...

(2014-04-01)This thesis presents the development of techniques used to investigate the combustion behavior of liquid monopropellants with or without additives, with a focus on nano-scale particles as burning rate modifiers in nitromethane. ...
-
(2009-05-15)A new fabrication process of organic and inorganic nanoparticles and cups by electrospraying blended polymer-sol-gel solutions followed by calcination has been investigated. Because of low viscosity and high surface tension ...
-
(2018-12-03)Viscoelastic surfactants were introduced in hydraulic fracturing fluids as a proppant carrier in order to replace polymers which possess high potential for formation damage. Yet, VES technology is limited by its low thermal ...
-
(2017-12-06)The use of engineered nanoparticles (ENPs) has drastically increased, resulting in the release of these particles into the environment; raising concerns over the impacts this could have on human food safety. Two ENPs of ...
-
(2017-11-28)The capabilities of different types of nanoparticles (NPs) had been exploited to develop a water-based drilling fluid having better characteristics for harsh drilling conditions. More specifically, the objectives of this ...
-
(2019-11-07)Crops and leafy vegetables are a rich source of protein, essential minerals, and fibers for the human diet, which may turn to toxic plants if exposed to heavy metals or metalloid contamination. Cadmium (Cd), Lead (Pb) and ...
-
(2009-05-15)The synthesis of solid state materials has traditionally been accomplished using rigorous heating treatments at high temperatures (1,000°C) to overcome the slow rate of diffusion between two reactants. Re-grinding and ...
-
(2012-02-14)This dissertation studies how nanoadditives influence burning rates through the development and use of a model to conduct parametric studies on nanoadditive interaction and to formulate theories. Decades of research have ...
