Colloidal nanoparticles are particles that operate at the nanoscale, specifically between 1 to 1000 nanometers, suspended in a fluid. These nanoparticles can consist of various materials, such as ...

Titanium dioxide (TiO 2) nanoparticles have a high refractive index (n = 2.4), making them ideal for various applications, including medicines, coatings, inks, plastics, food, cosmetics, and textiles.

Nanoparticles of titanium dioxide (TiO2) are commonly used in sunscreens as protection against ultraviolet radiation. Partly because the particles are so small, nanoscale TiO2 does not reflect visible ...

Evanston, IL In a paper to be published in Science Jan. 18, scientists Chad Mirkin and Sharon Glotzer and their teams at Northwestern University and University of Michigan, respectively, present ...

To better evaluate the impact on living organisms of the widespread presence of titanium dioxide in the environment and measure the real exposure of animals and humans, scientists from INRAE, AP-HP, ...

A physicist has proposed a new concept for treating cancer cells. A physicist at The University of Texas at Arlington has proposed a new concept for treating cancer cells. In a recently published ...

Zeta potential is a key indicator of the stability of colloidal dispersions and nanoparticle suspensions. It measures the electrical potential difference between the bulk of the liquid and the ...

Complex crystals that mimic metals -- including a structure for which there is no natural equivalent -- can be achieved with a new approach to guiding nanoparticle self-assembly. Complex crystals that ...

What if washing your favorite T-shirt didn’t require any washing whatsoever? Well, guess what. Science says it’s possible. Chemical engineers in China say they’ve developed a cotton fabric that cleans ...
