Biomimetic spinning of artificial spider silk. a) Highly concentrated spider silk protein solution in a syringe is pumped through a pulled glass capillary with a tip size of 10-30 mm, with the tip submerged into a low pH aqueous...
Researchers created an optomechanical silicon bullseye disk that traps optical waves in the outermost ring via total internal reflection while the radial groves confine the mechanical waves to the same area. Credit: Thiago P. Mayer Alegre, University of Campinas Researchers...
Steps for building DNA nanotube connections between molecular landmarks.Credit: Nature Nanotechnology, 2016, Abdul M. Mohammed et alia In a microscopic feat that resembled a high-wire circus act, Johns Hopkins researchers have coaxed DNA nanotubes to assemble themselves into bridge-like structures...
3-D-printed gyroid models such as this one were used to test the strength and mechanical properties of a new lightweight material.Photo: Melanie Gonick/MIT Porous, 3-D forms of graphene developed at MIT can be 10 times as strong as steel but...
Researchers have created a stretchy transistor that can be elongated to twice its length with only minimal changes in its conductivity. The development is a valuable advancement for the field of wearable electronics. To date, it has been difficult...
The STAR collaboration's exploration of the "nuclear phase diagram" shows signs of a sharp border--a first-order phase transition--between the hadrons that make up ordinary atomic nuclei and the quark-gluon plasma (QGP) of the early universe when the QGP is...

This is the first real-life study to provide data on the potential of powering medical implants with solar cells.Credit: Lukas Bereuter The notion of using solar cells placed under the skin to continuously recharge implanted electronic medical devices is a...
Example of diamond crystallites of different shapes, obtained with the help of the technology, worked out in the Lomonosov Moscow State University. There are electron microscopy images of diamond films' fragments after their oxidation in the air. The material...
Scaffold modelled using image-based Lattice Boltzmann method. LEFT: Calculated shear stress (SS). RIGHT: Soft tis-sue is subtracted using image processing. Images represent a 0.62 mm x 0.91 mm x 0.62 mm volume. In these images gray scale represents the...
