Silica Nanoparticles

2021
Silica consists of one silicon atom and two oxygen atoms (SiO2) and is commonly used in various aspects of daily life. For example, it has been used as glass, insulator, and so on. Nowadays, silica is used as core reagents for fabricating and encapsulating nanoparticles (NPs).

Upconverting Nanoparticles

Angewandte Chemie International Edition, 2011
AbstractUpconversion (UC) refers to nonlinear optical processes in which the sequential absorption of two or more photons leads to the emission of light at shorter wavelength than the excitation wavelength (anti‐Stokes type emission). In contrast to other emission processes based on multiphoton absorption, upconversion can be efficiently excited even ...

Toxicity of Nanoparticles

Current Medicinal Chemistry, 2014
Nowadays more than thousands of different nanoparticles are known, though no well-defined guidelines to evaluate their potential toxicity and to control their exposure are fully provided. The way of entry of nanoparticles together with their specificities such as chemistry, chemical composition, size, shape or morphology, surface charge and area can ...

Dielectrophoresis of Nanoparticles

Fluids Engineering, 2004
A numerical scheme based on the distributed Lagrange multiplier method (DLM) is used to study the motion of nano sized particles of dielectric suspensions subjected to uniform and nonuniform electric fields. Particles are subjected to both electrostatic and hydrodynamic forces, as well as Brownian motion.

Dissymmetrical Nanoparticles

2004
Half-way between molecular and materials chemistries lies the field of colloidal chemistry where the shape, the size, and the morphology of supramolecular assemblies are key parameters that determine their intrinsic properties, such as their interfacial behavior, surface chemistry, density, and so on.

Gelatin Nanoparticles

2019
Currently, gelatin nanoparticles are gaining more grounds in drug and gene delivery throughout all the available several routes of administration. Yet, the homogenous and less disperse preparation of this type of nanoparticles is still a challenging task due to the variation of the gelatin quality according to its source and due to its variable ...

Different Uptake of Metal Dioxide Nanoparticles (Ceria Nanoparticles, Zirconia Nanoparticles and Silica Nanoparticles) by Wheat

Bulletin of Environmental Contamination and Toxicology, 2019
Metal dioxide nanoparticles (NPs) are produced in ever-increasing amounts and widely used in industrial, medical and consumer products. They may pose potential risks to the environment. In this study we quantitatively evaluated the phytoavailability of CeO2NPs, ZrO2NPs and SiO2NPs to wheat (Triticum aestivum L.).

Novel nanoparticle matter: ZrN-nanoparticles

Applied Physics B, 2003
This work presents the results of the first preparation (to the best of current knowledge) and investigation of ZrN nanoparticles. The particles were produced by laser ablation/evaporation and adiabatic expansion from zirconium nitride powder targets. The particle size could be varied by applying different seeding gas flows. The size distributions were
