'Sticky tape' for water droplets mimics rose petal

(Phys.org) —A new nanostructured material with applications that could include reducing condensation in airplane cabins and enabling certain medical tests without the need for high tech laboratories has been developed by ...

Blocking infinity in a topological insulator

(Phys.org)—In bulk, topological insulators (TIs) are good insulators, but on their surface they act as metals, with a twist: the spin and direction of electrons moving across the surface of a TI are locked together. TIs ...

Moth-inspired nanostructures take the color out of thin films

Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" ...

Flaky graphene makes reliable chemical sensors

Scientists from the University of Illinois at Urbana-Champaign and the company Dioxide Materials have demonstrated that randomly stacked graphene flakes can make an effective chemical sensor.

Researchers measure puncture performance of viper fangs

A team that studies how biological structures such as cactus spines and mantis shrimp appendages puncture living tissue has turned its attention to viper fangs. Specifically, the scientists wanted to know, what physical characteristics ...

Physicists use oscillations of atoms to control a phase transition

The goal of 'femtochemistry' is to film and control chemical reactions with short flashes of light. Using consecutive laser pulses, atomic bonds can be excited precisely and broken as desired. So far, this has been demonstrated ...

Trapping butterfly wings' qualities

Butterflies have inspired humans since the time of ancient Egypt, but now they're also inspiring researchers to look toward nature to help create the next generation of waterproof materials for electronics and sensors.
