NICT Experiments with Quantum Dots to Increase Optic Fiber Bandwidth

Since you’re reading this blog, I’m going to assume you love the Internet nearly as much as I do. Not only does the Internet contribute to my household income, it entertains, informs and occasionally bewilders me. One potential threat (from my point of view) to the Internet is companies eventually cracking down on bandwidth. That would probably force me to pay for cable TV again, instead of streaming Hulu and Netflix.

That potential horror may yet be averted thanks to researchers at the Photonic Network Research Institute, which is itself part of Japan’s National Institute of Information and Communications Technology (NICT). Dr. Hideo Miyahara and his team have succeeded, “… in developing an optical source for generating light of a large number of wavelengths with high precision.” The scientists have dubbed this process “quantum dot light source technology.”

According to the NICT’s press release, the team has succeeded in building a high-speed data transmission system with error-free data transmission that combines this light source and the photonic crystal fiber with ultra-broadband optical propagation characteristics. That means more speed for data-hungry engineering applications, like simulation and rendering on the cloud (as well as the latest blockbuster).

Researchers Develop Solar Paint

Imagine if a fresh coat of paint could make your business more energy efficient, or could help power the  new electric car you’re helping design. Scientists at Notre Dame have used breakthroughs in semiconductor nanocrystal research to create a paint that collects solar energy. Researchers created the one-coat paint, which they have named “Sun-Believable,” by mixing CdS, CdSe, and TiO2 semiconductor nanoparticles.

 ”We want to do something transformative, to move beyond current silicon-based solar technology. By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we’ve made a one-coat solar paint that can be applied to any conductive surface without special equipment.”  — Notre Dame professor Prashant Kamat.

SME Innovation List Includes Programmable Magnets, Robot Substitutes

Engineers and designers are always keeping an eye out for new materials and manufacturing methods that could impact their designs. The Society of Manufacturing Engineers (SME) revealed its list of seven innovations that could change the way industry makes things earlier this year.

The list (Innovations That Could Change The Way You Manufacture) was compiled by SME’s Innovation Watch Committee.

“Our Committee’s goal is to scan the vast technology landscape for cutting-edge innovations and to investigate ways they can be utilized.” –Christopher Kaye, director of innovative technology, US Endoscopy, and member of the SME Innovation Watch Committee

This year’s innovations to watch:
