Antiviral applications of silver nanoparticles

Apr 24, 2020 10:44:36 AM / by Ara Parsekian posted in Nanoparticles


With the ongoing COVID-19 pandemic, the need for general-purpose antiviral materials has never been more relevant. Metallic nanoparticles, and silver nanoparticles (AgNPs) in particular, have received considerable attention through efforts to meet this need. But what is it that makes AgNPs effective against viruses? How has this effectiveness been measured and quantified? And how can AgNPs be incorporated into products and treatments effectively? Answers to these questions provided by the scientific community are invaluable for separating the facts from the hype.

Photonic curing and soldering

Apr 13, 2020 9:20:33 PM / by Rudy Ghosh posted in Photonic Soldering, Photonic Curing


How Does the Photonic Curing Process Work?

Light energy incident on a body will be absorbed and heat up the object. The light-matter interaction determines what fraction of light is reflected back, transmitted through or absorbed by the body. The fraction of light absorbed can be guessed by the color of the body (darker material absorbs more light). Light that is absorbed by the body is mostly converted to heat and shows up as an increase in its temperature. That’s why wearing a black shirt in the middle of a Texas summer isn’t the most comfortable thing to do.

Photonic soldering in printed electronics

Current Material Options

If you have ever disassembled any electronic device, you know that inside you’ll find a variety of components, such as resistors, capacitors, chips and controllers that make everything work. All of these components usually sit on a rigid board (with copper tracks on it) that allows these parts to talk to one another. A major consideration in the choice of materials for building conventional electronics is the material’s ability to withstand high temperature (a required step in building electronic devices). But if those high thermal requirements could be relaxed, it would open up a wide variety of material options which, in turn, would allow new forms and functionalities – while reducing unit costs.
