Printing Nanomaterials with Plasma

The nozzle firing a jet of carbon nanotubes with helium plasma off and on. When the plasma is off, the density of carbon nanotubes is small. The plasma focuses the nanotubes onto the substrate with high density and good adhesion. Credit: NASA Ames Research Center

New method can deposit nanomaterials onto flexible surfaces such as paper or cloth and 3-D objects.. The technique could make it easier and cheaper to build devices like wearable chemical and biological sensors, flexible memory devices and batteries, and integrated circuits.

One of the most common methods to deposit nanomaterials- such as a layer of nanoparticles or nanotubes -onto a surface is with an inkjet printer similar to an ordinary printer found in an office. But inkjets can’t print on textiles etc, let alone 3-D objects...

Google Glass meets Organs-on-Chips

Figure 1

Investigators from Brigham and Women’s Hospital (BWH) have developed hardware and software to remotely monitor and control devices that mimic the human physiological system. Devices known as organs-on-chips allow researchers to test drug compounds and predict physiological responses with high accuracy in a laboratory setting. But monitoring the results of such experiments from a conventional desktop computer has several limitations, especially when results must be monitored over the course of hours, days or even weeks.

Google Glass, one of the newest forms of wearable technology, offers researchers a hands-free and flexible monitoring system. To make Google Glass work for their purposes, Zhang et al...

Breakthrough Technology to Improve Cyber Security using Photons as Quantum information carriers

Photons are generated simultaneously in pairs, each in one of the photon streams. The detection of photons in one stream indicates the timing information of those in the other. Using this information, a proper timing control is dynamically applied to those photons so they appear at regular intervals. This new technique increases the rate of photons at the regular interval, which is extremely useful for quantum secure communication and quantum photonic computation. Credit: University of Sydney

A red bread mold could be the key to producing more sustainable electrochemical materials for use in rechargeable batteries. The researchers show for the first time that the fungus Neurospora crassa can transform manganese into a mineral composite with favorable electrochemical properties.

“We have made electrochemically active materials using a fungal manganese biomineralization process,” says Geoffrey Gadd of the University of Dundee in Scotland...
