A new electrolyte to make better Lithium-ion batteries
Researchers at NTNU are searching for materials that could be used to make Li-ion batteries with a higher energy density.

The tiny gold particles that can help harness energy from the sun to break down pollution
Researchers at NTNU have found a way to make gold nanoparticles with a uniform size and shape, opening up the possibility of finding more effective photocatalysts.

Snow-repelling solar cell panels could help Norway generate more electricity
Norway has seen an increase in solar power capacity in recent years, but in winter solar panels face a big problem: snow. Researchers at NTNU modelled how much extra electricity could be generated if solar panel surfaces were designed to repel snow and ice.

A counterintuitive way to make stronger alloys
By using a cutting edge technique to observe what’s happening at the atomic level inside their material, researchers at NTNU have discovered a surprising new method to make aluminium alloys stronger.

The lab-created colours inspired by feathers and soap bubbles
Birds, butterflies, and many other natural objects get their bright colours from intricate structures on their surfaces. Now researchers at NTNU have used the same principle to create colours with clay nanostructures.

Making materials for the next generation of electric car batteries
Batteries that can store more energy could help electric cars go the distance. But researchers at NTNU have discovered that one promising new battery material needs rethinking.
As drivers around the world switch to electric cars, new batteries that can store more energy, translating to longer driving distances before a car needs recharging, can’t come soon enough. However, Daniel Rettenwander and co-workers at NTNU have discovered that one promising material in the search for the next generation of batteries needs rethinking.

The tiny structures that mimic a cell’s natural environment
Covering glass microscope slides in tiny, nano-sized pillars can mimic a cell’s natural environment – and could help biologists understand how cells act inside the human body.
When biologists study cells under a microscope, they look at them on flat surfaces that are nothing like the environment inside the human body. Pawel Sikorski and co-workers have found a way to mimic some aspects of a cell’s native environment using tiny polymer pillars.
A new way to get cells to spill their secrets
Countless potentially useful enzymes are hidden all around us. Now a team of researchers at NTNU have developed a new method that could help us find them.
The natural world is a treasure trove of potentially useful enzymes, hidden in microorganisms living all around us. But finding them is tricky. A team of researchers, led by Rahmi Lale at NTNU have developed a new method to break open cells that could help in the quest.
How spider silk inspired a new material with extraordinary mechanical properties
Researchers at NTNU have developed a new elastomer with unprecedented stiffness and toughness, inspired by spider silk
Inspired by extremely strong spider silk, Zhiliang Zhang and coworkers at NTNU have developed a new material that defies previously seen trade-offs between toughness and stiffness.
Using real neural networks to pinpoint the start of brain disease
“In theory, if you can pinpoint the onset of the disease, you might be able to stop it or reverse some of its effects,” says Ioanna Sandvig, co-leader of the integrative neuroscience group at NTNU’s Department of Neuromedicine and Movement Science.
Sandvig and her colleagues are growing interconnected brain cells in the lab, to study how these neural networks evolve and what happens when things go wrong.

A new way to look at the inner workings of tiny magnets
Researchers at NTNU are shedding light on magnetic materials at small scales by creating movies with the help of some extremely bright x-rays.
Erik Folven, co-director of the oxide electronics group at NTNU’s Department of Electronic Systems, and colleagues from NTNU and Ghent University in Belgium set out to see how thin-film micromagnets change when disturbed by an outside magnetic field.
Capturing energy from sunlight with dyes inspired by nature
As sunlight filters through a forest canopy, chlorophyll is hard at work capturing the energy of photons. Inspired by nature, researchers at NTNU are working on light-capturing dyes for solar cells to generate electricity.
PhD candidate David Moe Almenningen and colleagues, Odd Reidar Gautun, Bård Helge Hoff and Svein Sunde have shown that adding a particular molecule to the dyes can increase its light harvesting properties – though so far the additional light comes at a cost.
How researchers solved a decade-long puzzle about friction
Sometimes, when it comes to friction, less is more – at least that’s what several experiments over the last decade seem to have shown in the case of friction caused by layered materials. But it wasn’t until recently that researchers at NTNU figured out what was actually going on.
The cause of friction in 2D layered materials has always been a bit of a theoretical sticking point, but research by David Andersson and Astrid de Wijn might just have got things moving again.
Moving towards an ‘artificial pancreas’ for people with diabetes
Living with diabetes often means having to prick your finger to test blood glucose levels several times a day.
That’s why a group of researchers in Trondheim are working on creating an “artificial pancreas” to take over this responsibility. The work is still in its early stages, but the ultimate aim is for the device to automatically measure glucose levels, and administer insulin according to the results, doing away with regular manual testing.
“Appealing” nanogap devices
As demand for faster and more powerful electronics grows, the size of individual components must shrink. Making these tiny components usually requires complicated techniques carried out in clean rooms with expensive equipment – but John de Mello, Bård Hoff and Sihai Luo from the Department of Chemistry at NTNU are working on a decidedly lower tech approach to making what will hopefully become high performance devices.
Creating a miniature brain-on-a-chip
Growing a brain in the lab might still be a far-fetched idea, but perhaps it just got one step closer.
Øyvind Halaas, a professor of medicine at NTNU, in collaboration with neuroscientists Ioanna and Axel Sandvig and others, has created a mini-“brain-on-a-chip”.
Using the piezoelectric effect to make better implants
Imagine a bone implant that actively stimulates the recovery of the damaged tissue slowly dissolves inside your body as it’s taken over by your own bone.
This new kind of implant is not a reality – yet. But, if Julia Glaum and her colleagues have anything to do with it, it could exist one day.
Cracking the problem of ice build-up
If you’ve ever set foot on an icy pavement you’ll understand the importance of a good de-icer. But ice doesn’t just get in the way of people’s daily lives. Infrastructure like aircraft, transmission cables, and offshore oil platforms can all be disrupted by ice, with potentially disastrous consequences.
That’s why Jianying He, a professor of nanomechanics at NTNU, and her colleagues are coming up with new ways to crack the problem of ice build-up.
Joined up thinking to make materials greener
A new research centre is about to give Norway a window into how its rich mineral resources can be turned into useful – and more environmentally-friendly – materials.
The Norwegian national centre for minerals and materials characterisation, known as MiMaC for short, promises to look at every step of the process of turning minerals into materials. The centre is a joint project of NTNU, the Geological Survey of Norway and research company SINTEF.
Creating a new kind of electronics
At the border between physics and material science, Dennis Meier and his colleagues are searching for a new kind of electronics.
They hope to make circuits that are smaller, faster, and better for the environment than today’s electronics, by taking advantage of defects that already exist within materials.
