Water compresses under a high gradient electric field

04-Jul-2018

Modern civilization relies on water's incompressibility--it's something we take for granted. Hydraulic systems harness the virtual non-compressibility of fluids like water or oil to multiply mechanical force. Bulldozers, cranes, and other heavy machinery exploit the physics of hydraulics, as do ...

3D X-rays measure particle movement inside lithium ion batteries

23-May-2018

Lithium ion batteries have come a long way since their introduction in the late 1990s. They're used in many everyday devices, such as laptop computers, mobile phones, and medical devices, as well as automotive and aerospace platforms, and others. However, lithium ion battery performance still can ...

Graphene origami as a mechanically tunable plasmonic structure for infrared detection

26-Apr-2018

Soldiers often need to see through smoke, fog, dust or any other airborne obscurant and detect the presence of toxins or other chemicals in the field or on the front lines. To identify those chemicals, they use infrared (IR) sensors and spectroscopy, which allow a specific color of light to shine ...
