More pathways that previously thought can lead to optical topological insulators
The candidate pool for engineered materials that can help enable tomorrow’s cutting-edge optical technologies—such as lasers, detectors and imaging devices—is much deeper than previously believed.
That’s according to new research from the University of Michigan that examined a class of materials known as topological insulators. These materials have exciting and tunable properties when it comes to how they transmit energy and information.
“We see this as a step toward building a more versatile and powerful foundation for future photonic technologies,” said Xin Xie, a research fellow in the U-M Department of Physics and lead author of the recent study in the journal Physical Review X.
Sustainable cooling film could slash building energy use by 20% amid rising global temperatures
An international team of scientists has developed a biodegradable material that could slash global energy consumption without using any electricity, according to a new study published today.
The bioplastic metafilm—that can be applied to buildings, equipment and other surfaces—passively cools temperatures by as much as 9.2°C during peak sunlight and reflects almost 99% of the sun’s rays.
Developed by researchers from Zhengzhou University in China and the University of South Australia (UniSA), the new film is a sustainable and long-lasting material that could reduce building energy consumption by up to 20% a year in some of the world’s hottest cities.

Three-mode smart window cut indoor temperature by 27°C and eliminate urban glare
In the building sector, which accounts for approximately 40% of global energy consumption, heat ingress through windows has been identified as a primary cause of wasted heating and cooling energy.
A KAIST research team has successfully developed a ‘pedestrian-friendly smart window’ technology capable of not only reducing heating and cooling energy in urban buildings but also resolving the persistent issue of ‘light pollution’ in urban living.
Professor Hong Chul Moon’s research team at KAIST’s Department of Chemical and Biomolecular Engineering have developed a ‘smart window technology’ that allows users to control the light and heat entering through windows according to their intent, and effectively neutralize glare from external sources.
A framework for realizing a microscopic, highly precise and energy-efficient quantum clock
Over the past decades, physicists have been trying to develop increasingly sophisticated and precise clocks to reliably measure the duration of physical processes that unfold over very short periods of time, helping to validate various theoretical predictions. These include so-called quantum clocks, timekeeping systems that leverage the principles of quantum mechanics to measure time with extremely high precision.
DARPA program sets distance record for power beaming
Previously, the greatest reported distance records for an appreciable amount of optical power (1 microwatt) were 230 watts of average power at 1.7 kilometers for 25 seconds and a lesser (but undisclosed) amount of power at 3.7 kilometers.
“It is beyond a doubt that we absolutely obliterated all previously reported optical power beaming demonstrations for power and distance,” said POWER Program Manager Paul Jaffe after the results were confirmed. The DARPA-led team brought together industry and government, including the U.S. Naval Research Laboratory and the High Energy Laser Systems Test Facility (HELSTF) at the U.S. Army’s White Sands Missile Range.
Energy is a fundamental requirement for military operations, and traditional means of getting energy to the edge (battlefields, disaster zones, etc.) are often incredibly slow, risky, and resource intensive. These tests, referred to as PRAD (POWER Receiver Array Demo), mark an important step towards the POWER program’s long-term goal of being able to instantly beam power from a location where it can be easily generated to wherever it’s needed, opening a novel design space for platform capabilities unbounded by fuel limitations.
