By  Jules Bernstein A new film made of gold nanoparticles changes color in response to any type of movement. Its unprecedented qualities could allow robots to mimic chameleons and octopi — among other futuristic applications. Unlike other materials that try to emulate nature’s color changers, this one can respond to any type of movement, like…

By Chris Adam A team of Purdue University innovators has developed a new way for manufacturers to use nanocellulose – a green nanomaterial derived from natural sources such as plant matter, for use in vehicles, food packaging and other manufactured items. Normally to process nanocellulose, solvents or other dispersants are usually added to the mixture…

Written by Jennifer Chu, MIT News Office MIT engineers have designed a “brain-on-a-chip,” smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors — silicon-based components that mimic the information-transmitting synapses in the human brain. The researchers borrowed from principles of metallurgy to fabricate each…

To answer the demand for an integrated inverted microscope-positioning system that must match perfectly, PI (Physik Instrumente), a leader in precision motion control and nanopositioning solutions, has released an interactive brochure to aid in building the system by beginning with a fine positioner and/or a sample holder. Stages with piezo nanopositioning are incorporated to satisfy…

By Steve Varma, Operations Manager, Minus K Technology The Ultra-Low Vibration Lab is a part of the new Center of Excellence in Nano Mechanical Science and Engineering (NAMSE) – a recent addition to the G.G. Brown Laboratories on the North Campus of the University of Michigan in Ann Arbor. Noel Perkins, former associate chair for…

Since their invention in the 1930s, electron microscopes have helped scientists peer into the atomic structure of ordinary materials like steel, and even exotic graphene. But despite these advances, such imaging techniques cannot precisely map out the 3D atomic structure of materials in a liquid solution, such as a catalyst in a hydrogen fuel cell,…

Park Systems, manufacturer of Atomic Force Microscopes, announces a $1 Million Dollar Nano Research Grant Fund to support researchers who are starting new nanoscience labs in North America.

  Computer chips use billions of tiny switches, called transistors, to process information. The more transistors on a chip, the faster the computer. A material shaped like a one-dimensional DNA helix might further push the limits on a transistor’s size. The material comes from a rare earth element called tellurium. Researchers found that the material,…

By Ken Strandberg The European X-ray Free-electron Laser (European XFEL), recently completed its first experiments that captured images of an antibiotic-disabling enzyme.
