This 3D printer can figure out how to print with an unknown material
This 3D printer can figure out how to print with an unknown material
The advance could help make 3D printing more sustainable, enabling printing with renewable or recyclable materials that are difficult to characterize. While 3D printing has exploded in popularity, many of the plastic materials these printers use to create objects cannot be easily recycled. While new sustainable materials are emerging for use in 3D printing, they remain difficult to adopt because 3D printer settings need to be adjusted for each material, a process generally done by hand.

A first-ever complete map for elastic strain engineering
New research by a team of MIT engineers offers a guide for fine-tuning specific material properties. Without a map, it can be just about impossible to know not just where you are, but where you're going, and that's especially true when it comes to materials properties. For decades, scientists have understood that while bulk materials behave in certain ways, those rules can break down for materials at the microand nano-scales, and often in surprising ways.

New method developed to isolate HIV particles
New method developed to isolate HIV particles
Researchers at Leipzig University and Ulm University have developed a new method to isolate HIV from samples more easily, potentially making it easier to detect infection with the virus. They focus on peptide nanofibrils (PNFs) on magnetic microparticles, a promising tool and hybrid material for targeted binding and separation of viral particles.

Results for: Schulich researchers develop new ways to make stronger metals
Materials engineers have spent decades trying to make stronger metals by making their constituent crystals - their grains - smaller. And we mean small: to the nanoscale. That's because the smaller the grain, generally the stronger, tougher and lightweight the metal can be, while less energy is consumed and emitted when it's used in structural applications.

3D images reveal link between crack complexity and material toughness
3D images reveal link between crack complexity and material toughness
By capturing a rare glimpse into three-dimensional crack formation in brittle solids, researchers have found that complex cracks require more energy to advance than simple ones; a discovery that could improve materials testing and development. The last time you dropped a favorite mug or sat on your glasses, you may have been too preoccupied to take much notice of the intricate pattern of cracks that appeared in the broken object.

Parity anomaly detected in topological insulator
Experimental and theoretical physicists at the Würzburg Institute for Topological Insulators have identified an unusual quantum Hall effect in a mercury telluride device as the signature of the parity anomaly . Topological insulators are materials that can conduct electricity, but only on their surface or edges.

New Method for Analysing Nanoporous Materials
New Method for Analysing Nanoporous Materials
Using only a single electron microscope image, researchers at TU Graz can determine the type and exact position of so-called guest atoms in high-tech materials. They also come closer to solving the mystery of the blue colour of aquamarine. In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure.

World’s first high-resolution brain developed by 3D printer
In a joint project between MedUni Vienna and TU Wien, the world's first 3D-printed "brain phantom" has been developed, which is modelled on the structure of brain fibres and can be imaged using a special variant of magnetic resonance imaging (dMRI). As a scientific team led by MedUni Vienna and TU Wien has now shown in a study, these brain models can be used to advance research into neurodegenerative diseases such as Alzheimer's, Parkinson's and multiple sclerosis.

Future nuclear power reactors could rely on molten salts - but what about corrosion?
MIT researchers show that using the right metals could alleviate the corrosion problem in these promising new reactor designs. Most discussions of how to avert climate change focus on solar and wind generation as key to the transition to a future carbon-free power system. But Michael Short, the Class of '42 Associate Professor of Nuclear Science and Engineering at MIT and associate director of the MIT Plasma Science and Fusion Center (PSFC), is impatient with such talk.

Mystery of Curling Paper Solved
Mystery of Curling Paper Solved
Paper printed on one side starts to curl with a delay of up to a few days. Researchers at TU Graz have discovered that this is due to solvents in the ink that over time migrate towards the unprinted side of the paper. Although mankind has been using paper for at least 2000 years, it still presents us with one or two mysteries.
