In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers. Similar to ultrafine particles, nanoparticles are sized between 1 and 100 nanometers.

Sand and Multiple Light Scattering
23 Aug 2021 | | Contributor(s):: Denise Kapler, NNCI Nano
Nanoparticles and other nanoscale materials are often analyzed through the specialized use of light scattering. Several techniques use the light scattered from small particles to estimate their size distribution; these techniques employ light absorption, laser diffraction, and dynamic light...
Optical and Thermodynamic Properties of Gold Metal Nanoparticles - Effect of Chemical Functionalization
27 May 2021 | | Contributor(s):: Baudilio Tejerina, George C. Schatz, Marcelo Carignano
This laboratory is intended to introduce the student to the use of semiempirical electronic structure methods. In particular, the semiempirical methods will be applied to the study of metallic clusters and the interaction of the clusters with discrete molecular systems such as pyridine.

04 Feb 2021 | | Contributor(s):: Vikram Jadhao
I will describe the nanoHUB tool “Nanoparticle Shape Lab” that enables simulations of the shape deformation of charged nanoparticles for a broad variety of nanoparticle material properties including nanoparticle surface charge, pattern, elasticity and solution conditions such...
The Effect of Sulfidation on Solubility of Silver Nanoparticles On Water Treatment Membranes
12 Jan 2021 | | Contributor(s):: Richard Daines, NEWT Center
This whiteboard video is designed to engage K-12 students in high-level nanotechnology research. Biofouling hinders water treatment membranes. Coating them with silver nanoparticles (AgNPs) increases their antimicrobial biofouling resistance. Unfortunately, AgNPs are soluble,...
