Molecular vibrations lead to high performance laser

Lasers. They are used for everything from entertaining our cats to encrypting our communications. Unfortunately, lasers can be energy intensive and many are made using toxic materials like arsenic and gallium. To make lasers ...

Next-generation optics in just two minutes of cooking time

Optical circuits are set to revolutionize the performance of many devices. Not only are they 10 to 100 times faster than electronic circuits, but they also consume a lot less power. Within these circuits, light waves are ...

Gradation-tint smart window

NIMS, Waseda University and Tama Art University developed together smart glass capable of producing various shades on its surface. Unlike the conventional types, the newly developed tinting smart glass allows users to easily ...

Controlling ultrasound with 3-D printed devices

Ultrasound is more than sound. Obstetricians use it to peer inside a woman's uterus and observe a growing baby. Surgeons use powerful beams of ultrasound to destroy cancer cells. Researchers fire ultrasound into materials ...

Towards better metallic glasses

Researchers from the University of Bristol have used state-of-the-art computer simulation to test a theory from the 1950s that when atoms organise themselves into 3D pentagons they supress crystallisation.

Graphene cracks the glass corrosion problem

Researchers at the Center for Multidimensional Carbon Materials (CMCM), within the Institute for Basic Science (IBS) have demonstrated graphene coating protects glass from corrosion. Their research, published in ACS Nano, ...
