Help.

My #ADHD, interest in new tech breakthroughs and love of #shiny things has trapped me on this page about #sequins made from #nanocellulose.

I can't leave. Can't stop looking. It's... So shiny. Haaaalp.

A #nanocellulose #wound dressing that can reveal early signs of #infection without interfering with the #healing process has been developed by researchers at Linköping University.

Some close-up shots of the Renewal #acrylic #paintings on #FibDex #nanocellulose. Abstracted #birch #tree.

Detail of acrylic painting of lozenge-ish shaped leaves of an abstracted birch tree in greens, teal, yellow, and dark blue painted on white background.

Detail of thin and translucent layers of acrylic paint in yellow, dark blue, and teal on white background. Black inky brush strokes of the abstracted birch tree trunk on the left.

In preparation for painting Renewal I&II on #FibDex, I experimented with small cuts of the #nanocellulose material, testing how the #acrylic paint would sit on and be absorbed by the material. The image shows a progression from raw material (bottom) and raw material with acrylic paint (bottom right) to increasing layers of thin acrylic gesso added to the material before painting. The top piece has three layers of gesso.

Four smallish sheets of nanocellulose material fanned out on a light wood surface, sheets overlapping each other from bottom left to upper right. Progressive layers of white acrylic gesso and paint. Tiny rectangle of raw material on bottom right with blots of acrylic paint looking like watercolour to demonstrate the absorbtive quality of the material.

Two #acrylic compositions painted on strips of #nanocellulose wound dressing, known as #FibDex, which is used to treat wounds and burns to the skin. This product is derived from #birch tree cellulose and was developed by Prof Marjo Yliperttula of Helsinki University.

3D Printed Transistor Goes Green

We'll be honest, we were more excited by Duke University's announcement that they'd used carbon-based inks to 3D print a transistor than we were by their assertion that it was recyclable. Not that recyclability is a bad thing, of course. But we would imagine that any carbon ink on a paper-like substrate will fit in the same category. In this case, the team developed an ink from wood called nanocelluose.

As a material, nanocellulose is nothing new. The breakthrough was preparing it in an ink formulation. The researchers developed a method for suspending crystals of nanocellulose that can work as an insulator in the printed transistors. Using the three inks at room temperature, an inkjet-like printer can produce transistors that were functioning six months after printing.

The technology uses carbon nanotubes for the semiconductor material and graphene for the conductors. The addition of mobile sodium ions via sodium chloride to the insulating material improved the resulting transistor's performance.

Of course, right now this isn't a commercial technology, but we have to wonder if this isn't something hackers could do. Modifying an inkjet printer isn't hard to imagine. Preparing the ink may or may not be in the realm of the basement lab.

This looks conceptually simpler than the last electronics printer we talked about. Maybe you want your 3D printed semiconductors a bit less practical.
