Keeping Nanophotonics Cool

Yichen contributed to MIT research related a new radiative cooling approach.

MIT researchers have devised a new way of providing cooling on a hot sunny day, using inexpensive materials and requiring no fossil fuel-generated power. The passive system could be used to supplement other cooling systems to preserve food and medications in hot, off-grid locations.

In theory, the system they designed could provide cooling of as much as 20 degrees Celsius (36 degrees Fahrenheit) below the ambient temperature in a location like Boston, the researchers say. So far, in their initial proof-of-concept testing, they have achieved a cooling of 6 C (about 11 F).

New Technology: Transparent Display

Lux Labs has incorporated a new technology into our portfolio. Wavelength-selective scattering film invented at MIT can be used as a transparent display — a new, innovative form of marketing and signage. Our first prototype was fabricated in July 2018 (shown in the pictures below). The rapid progress being made to the transparent display technology and its aesthetic qualities demonstrates the promise and potential our film can bring to the advertisement industry among others.

We are going to Space

Lux Labs has been awarded a grant from the Center for the Advancement of Science in Space (CASIS) to conduct an experiment on the International Space Station (ISS). The goal of our experiment is to improve the understanding of the physics of multilayer polymer formation and the crystallization process. An improved understanding will help us determine better methods to fabricate more durable films that have advanced optical and mechanical properties, as well as benefit the broader, multi-billion dollar polymer industry. CASIS, collaborating with NASA, will take our samples to the ISS where astronauts will conduct the experiment. We will run a control experiment on Earth's surface. Takeoff is scheduled for mid-2019.  

Company Launch


Lux Labs, Inc. was incorporated in June 2017 and subsequently closed a seed investment round in August 2017. Lux Labs is an advanced optical materials company which aims to improve electronic displays, windows, and solar energy efficiency with our breakthrough optical angular selective film.  More information is available upon request.
