Controlling electronics with light: Ultrafast lasers manipulate magnetite’s structure

Posted by in categories: electronics, materials

Researchers at EPFL have discovered that by shining different wavelengths (colors) of light on a material called magnetite, they can change its state, e.g., making it more or less conducive to electricity. The discovery could lead to new ways of designing new materials for electronics such as memory storage, sensors, and other devices that rely on fast and efficient material responses.

Hard Yet Stretchable: Scientists Create “Unbreakable” New Material

Posted by in categories: biotech/medical, materials

Researchers have created a new class of materials called “glassy gels” that are as hard as glassy polymers, but – if you apply enough force – can stretch up to five times their original length, rather than breaking. A key thing that distinguishes glassy gels is that they are more than 50% liquid, which makes them more efficient conductors of electricity than common plastics that have comparable physical characteristics.

Researchers have developed a new class of materials known as glassy gels, which combine the hardness of glassy polymers with the stretchability of gels.

Turning infrared light visible: New device uses 2D material to up-convert infrared light

Posted by in category: materials

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than red light. Researchers at the Indian Institute of Science (IISc) have now fabricated a device to increase or “up-convert” the frequency of short infrared light to the visible range.

Generation of intense terahertz waves with a magnetic material

Posted by in category: materials

Terahertz waves are being intensely studied by researchers around the world seeking to understand the “terahertz gap.” Terahertz waves have a specific frequency that puts them somewhere between microwaves and infrared light. This range is referred to as a “gap” because much remains unknown about these waves.

A method to reversibly control Casimir forces using external magnetic fields

Posted by in categories: materials, quantum physics

The so-called Casimir force or Casimir effect is a quantum mechanical phenomenon resulting from fluctuations in the electromagnetic field between two conducting or dielectric surfaces that are a short distance apart. Studies have shown that this force can be either be attractive or repulsive, depending on the dielectric and magnetic properties of the materials used in experiments.
