Luminescent Windows Generate Energy from Inside and Out

Polymer cores redirect light from any source to solar cells.

Thermochromic Photovoltaic Windows

The windows reduce the need for air conditioning and simultaneously generate electricity.

Nanoparticle Gel Unites Oil and Water in Manufacturing-Friendly Approach

This novel gel-creation method could open applications in water filtration, batteries, and smart windows.

Cost-Effective Day & Night Marking Using Lasers

The marking provides easy-to-see legends on plastic buttons under widely varying illumination conditions.

Smart Window Improves Energy Efficiency of Buildings

A customizable smart window harnesses and manipulates solar power to save energy and cut costs.

Smart Windows Self-Illuminate on Rainy Days

Self-powering, color-changing humidity sensors are applicable to various fields including smart windows, health care, and safety management.

Optical Window for Far-IR Instruments Using Thin TOPAS® Film

This thin film can be used for ground-based and airborne applications in aircraft, balloons, and other flight missions.

Tuning Material Color and Thermal Properties Separately

The color of a material can often tell how it handles heat. With clothing, for example, the darker the pigment, the warmer you're likely to feel on a hot day. Likewise, the more...

Coating Prevents Fogging on Transparent Surfaces

Anyone who skis, wears glasses, uses a camera, or drives a car is familiar with the problem: Coming into a humid environment from the cold causes eyewear, camera lenses, or windshields to...

See-Through Film Rejects 70 Percent of Incoming Solar Heat

A heat-rejecting film was developed that could be applied to a building’s windows to reflect up to 70 percent of the Sun’s incoming heat. The film remains highly transparent...

X-Ray Study of Low-Density Materials

It's hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. Sandia studies myriads of low-density materials,...

Inductive Non-Contact Position Sensor

The Inductive Non-Contact Position Sensor is a highly accurate sensor for motion control applications. The sensor was designed to monitor the precise movements of an optical inspection system that...

Thermochromic Windows Convert Sunlight into Electricity

Relying on advanced materials such as perovskites and single-walled carbon nano-tubes, a window technology was developed that responds to heat by transforming from transparent to...

Composite Film Enables Windows that Switch from Transparent to Color

Commercial buildings in the United States account for nearly 40% of the total energy consumption. Among them, electricity is the largest energy source for buildings....
