Laser Light Sheet Offers Insight into Snowflake Acceleration
SALT LAKE CITY, Utah, Dec. 25, 2023 — A winter wonderland calls to mind piles of fluffy, glistening snow. But to reach the ground, snowflakes are swept into the turbulent atmosphere, swirling through the air instead of plummeting directly to the ground. The path of precipitation is complex but important to more than just skiers assessing the potential powder on their alpine vacation or school children hoping for a snow day. Determining snowflake fall speed is crucial for predicting weather patterns and measuring climate
Computational Imaging Enables a Camera to Use a Window as a Lens
SALT LAKE CITY, Utah, Aug. 22, 2018 — An engineering team from the University of Utah has found a way to use a regular pane of glass or any see-through window as a camera lens. The technique uses a computer algorithm to identify and decode the image, instead of a lens. Professor Rajesh...
Dark Sky Association Hosts Events to Call Attention to Light Pollution
SNOWBIRD, Utah, March 6, 2018 — The International Dark-Sky Association’s (IDA’s) 30th Annual General Meeting will be held Nov. 9 to 10, followed by the Artificial Light at Night’s (ALAN’s) 5th International Conference Nov. 12 to 15. The ALAN conference will...
Liquid Lens Paired With Infrared Light and a Smartphone Creates Smart Glasses
SALT LAKE CITY, Jan. 26, 2017 — Liquid-based lenses that automatically focus on what a person is seeing could replace reading glasses and bifocals in the near future. The human eye has a lens inside that adjusts the focal depth depending on what is being viewed. But as people age,...

Food Waste Transformed into LEDs
SALT LAKE CITY, Oct. 14, 2015 — LEDs made from sugary drinks could reduce waste and replace other light sources made with toxic elements. University of Utah researchers have developed a process for turning food, beverages and even combustion exhaust into light-emitting quantum...
Printable Filters Manage THz Communications
SALT LAKE CITY, Feb. 27, 2015 — Filters created with an off-the-shelf inkjet printer could enable blazing-fast wireless downloads and clearer cellphone calls using the terahertz spectrum. University of Utah researchers developed the filters, which are created with silver-metal ink...
Metamaterial Polarizing Filter Brightens LCDs, Photos
SALT LAKE CITY, Nov. 21, 2014 — Polarizers are vital for LCDs and photography, but they waste energy by blocking enormous amounts of light. A new filter skirts this obstacle. A team from the University of Utah developed the polarizing filter, which allows more light in to increase...
Nuclear Spins Boost Electric Current in OLEDs
SALT LAKE CITY, Sept. 19, 2014 — A spintronic approach has been used to power plastic organic LEDs at room temperature and without strong magnetic fields. “We have shown we can use room-temperature, plastic electronic devices that allow us to see the orientation of the...
Microstructures Improve Data Transfer
SALT LAKE CITY, March 12, 2014 — Microscopic structures that use light in metals to relay information could improve the speed of wireless technology and enable the printing of magnetic materials.
Tunable polymer could make truly white OLEDs
SALT LAKE CITY – Doping an organic polymer with platinum atoms makes the light it emits tunable, which could lead to the realization of cheaper, more efficient and truly white OLEDs. Existing white OLED displays use different organic polymers that emit different...

The Road from R&D to Commercialization
Jun 1, 2013 — Technology transfer programs in the US and abroad are champions to entrepreneurship, offering an effective model of how to turn ideas and innovation in photonics into commercial success. When US legislators formed NASA in the late 1950s,...
Solar Cell Material Made in the Microwave
SALT LAKE CITY, May 13, 2013 — Most people use microwaves to reheat leftovers, and some even experiment with marshmallows, inflating them like a balloon; but what if you could use the same home oven to make solar cells?
Utah Engineers Pioneer New Field in Materials Science
SALT LAKE CITY, Feb. 20, 2013 — Shuttling information at the speed of light in quantum computers and other high-speed electronic devices may be feasible with organic materials that conduct electricity on their edges, but acts as an insulator inside, new theoretical calculations...
The risks of “pay to play” in open access publishing
Sep 28, 2012 — In my last post, I discussed the potential impact of a move toward open access in academic publishing — in particular, with respect to commercial publishers and their bottom line. Publishers aren’t the only ones who might be affected,...
