Printing 3-D graphene structures for tissue engineering

Ever since single-layer graphene burst onto the science scene in 2004, the possibilities for the promising material have seemed nearly endless. With its high electrical conductivity, ability to store energy, and ultra-strong and lightweight structure, graphene has potential for many applications in electronics, energy, the environment, and even medicine. Now a team of Northwestern University …

Reinforced microfibers for soft hydrogels are a breakthrough for printed cartilage for 3D printed body parts

QUT biofabrication team has made a major breakthrough by 3D printing mechanically reinforced, tissue engineered constructs for the regeneration of body parts. In an article published in Nature Communications, the biomedical engineers outlined how they had reinforced soft hydrogels via a 3D printed scaffold. Professor Dietmar W. Hutmacher, from QUT’s Institute of Health and Biomedical …

DARPA N-ZERO “Asleep-Yet-Aware” Electronics Could lower power usage of Remote Wireless Sensors by 1000 times

DARPA wants to make sensors phenomenally more efficient in how they draw power when not actually sensing something of interest. The goal is to use less than 10 nanowatts (nW) during the sensor’s asleep-yet-aware phase—an energy drawdown roughly equivalent to the self-discharge (battery discharge during storage) of a typical watch battery, and at least 1,000 …

Low dose radiation is not harmful and the US will finally take about seven years to actually figure out the effects

After about 70 years of assuming that low dose radiation was harmful, the US Department of Energy (DOE) and National Academy of Sciences have been directed to work together to assess the current status of US and international research on low-dose radiation and to formulate a long-term research agenda under a bill approved by the …

‘Direct writing’ of diamond patterns from graphite a potential technological leap

A new technique uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips. “The biggest advantage is that you can selectively deposit nanodiamond on rigid surfaces without the high temperatures and pressures normally needed to produce synthetic diamond,” said Gary Cheng, an associate professor …
