Thinning a material down to a single-atom thickness can dramatically change that material’s physical properties. Graphene, the best known two-dimensional (2D) material, has...

A working, rechargeable proton battery was developed that could store more energy than currently available lithium-ion batteries. Potential applications include household storage of...

Electric vehicles are growing in popularity, and while they represent a cleaner alternative to fossil-fueled vehicles, their increased use may stress the grid if this growing load is left unmanaged. A need...

Two-photon lithography (TPL), a high-resolution 3D printing technique, is capable of producing nanoscale features smaller than 1/100 the width of a human hair. The technique could enable X-ray...

Water heaters and other thermal energy storage devices increase the temperature of a medium above an ambient or normal temperature, and store the warmer medium. Water heaters, in particular, must store...

Researchers have created a material that consists of carefully structured molecules designed to be particularly electrochemically stable in order to prevent the battery from losing energy to unwanted reactions....

In 3D printing — also known as additive manufacturing — an object is built layer-by-layer, allowing for the creation of structures that would be impossible to manufacture by...

Highly capable small Unmanned Aerial Vehicles (UAVs) provide substantial business opportunity, especially if allowed to operate in the suburban market. Reliability issues force the use of a safety pilot for each vehicle...

Batteries and combustion engines each have distinctive benefits and limitations. Batteries have simple construction and operate silently; however, their energy density (i.e., the energy per unit volume) is poor, and...

Researchers have developed a lithium-ion battery that uses a water-salt solution as its electrolyte — reaching the 4.0- Volt mark for electronics such as laptops — without the fire and...

In London's St. Paul's Cathedral, a whisper can be heard far across the circular whispering gallery as the sound curves around the walls. Now, an optical whispering gallery mode resonator developed by...
