AI Advances 3D Printing With Soft Materials
Additive manufacturing, also known as 3D printing, is a burgeoning technology increasingly being leveraged in the biomedical space. And it's not just for devices - 3D printing is being used increasingly to print organic tissues and soft materials, such as elastomers. While 3D printing soft materials, such as with silicone or proteins, offers many distinct advantages, it introduces many complicated variables to consider when creating new parts or materials.

Better thermal conductivity by adjusting the arrangement of atoms
Better thermal conductivity by adjusting the arrangement of atoms
Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone.

First-ever visualisations of electrical gating effects on electronic structure could lead to longer-lasting devices
First-ever visualisations of electrical gating effects on electronic structure could lead to longer-lasting devices
Scientists have visualized the electronic structure in a microelectronic device for the first time, opening up opportunities for finely tuned, high-performance electronic devices. Physicists from the University of Washington and the University of Warwick developed a technique to measure the energy and momentum of electrons in operating microelectronic devices made of atomically thin - so-called 2D - materials.

A Graphene Superconductor That Plays More Than One Tune
A Graphene Superconductor That Plays More Than One Tune
W hat's thinner than a human hair but has a depth of special traits' A multitasking graphene device developed by researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). The superthin material easily switches from a superconductor that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, and back again to a superconductor - all with a simple flip of a switch.

5000 tons of plastic released into the environment every year
5000 tons of plastic released into the environment every year
In order to estimate for the first time the exact extent of plastic pollution in Switzerland, the Federal Office for the Environment (FOEN) has mandated Empa researchers to calculate how much plastic gets into the environment. Empa has analyzed the seven most frequently used types of plastic. According to the study, more than 5000 tons of plastic are discharged into the environment every year.

The most successfull flat share in the world
The most successfull flat share in the world
Biofilms are enormously resistant accumulations of germs, which can cause serious problems, especially in hospitals. Like a single large creature, they can spread within wounds or colonize implants or biomedical products. With novel materials and surfaces researchers intend to combat the sturdy pathogens.

Why do bones fail?
Can analytical methods from materials science help us better understand human bones' A research team at Empa in Thun is pursuing precisely this approach. Osteoporosis is a wide­spread disease. Every third woman and every fifth man are affected by bone loss with ad­vanc­ing age. A frequent consequence of this is a fracture of the femoral neck - a painful injury that massively impairs the quality of life of those affected.

Deceptively real
The human heart still poses great challenges to modern medicine. More than ten million people in Europe suffer from heart failure, and quite a few of them need a donor organ. Artificial heart pumps are used to bridge the waiting time, but complications are not uncommon. The "Zurich Heart" project, in which Empa is a partner, is developing solutions.

Scars: gone with the foam
Scars: gone with the foam
Poorly healing wounds and severe scarring are more than just a cosmetic problem; they can significantly impair a person's mobility and health. Empa researchers have now developed a foam that is supposed to prevent excessive scarring and help wounds to heal quickly. An essential ingredient: the yellow ginger tumeric.

Wood on our Skin
Wood on our Skin
Physiological parameters in our blood can be determined without painful punctures. Empa researchers are currently working with a Canadian team to develop flexible, biocompatible nanocellulose sensors that can be attached to the skin. The 3D-printed analytic chips made of renewable raw materials will even be biodegradable in future.

New technique could brighten screens and make smartphone batteries last longer
Our future TV and smartphone screens could have double the energy efficiency, thanks to a technique invented by Imperial scientists. The pixels in many modern screens for TVs, smartphones, tablets, and laptops are lit by little devices called OLEDs (organic light emitting diodes). The findings could make screens of all kinds brighter, with better contrast and longer life.

With Little Training, Machine-Learning Algorithms Can Uncover Hidden Scientific Knowledge
Sure, computers can be used to play grandmaster-level chess , but can they make scientific discoveries' Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have shown that an algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge.

When CubeSats meet asteroid
When CubeSats meet asteroid
ESA's Hera mission for planetary defence, being designed to survey the smallest asteroid ever explored, is really three spacecraft in one. The main mothership will carry two briefcase-sized CubeSats, which will touch down on the target body. A French team has been investigating what might happen at that initial instant of alien contact.

Researchers pioneer method to purify water using solar energy
As the global population grows, fresh water supplies are more precious than ever. While scientists and engineers know how to purify water, making those methods sustainable and energy efficient is another question. One promising approach is solar-driven distillation, or solar steam generation, which can help us get fresh water from wastewater or seawater.

New findings could lead to cheaper solar cells
Effective atomic interactions in complex materials picked up by on-the-fly machine-learning At the atomic scale materials can show a rich palette of dynamic behaviour, which directly affects the physical properties of these materials. For many years, it has been a dream to describe these dynamics in complex materials at various temperatures using computer simulations.

Perovskite solar cells tested for real-world performance - in the lab
Perovskite solar cells tested for real-world performance - in the lab
Researchers bring diurnal and seasonal variations into the lab to test the performance of perovskite solar cells under realistic conditions. It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells made are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.

You Don’t Have to Be Perfect for TMDCs to Shine Bright
Atomically thin semiconductors known as TMDCs (transition metal dichalcogenides) could lead to devices that operate more efficiently than conventional semiconductors in light-emitting diodes, lasers, and solar cells. But these materials are hard to make without defects that dampen their performance.

Groundbreaking Study Maps Out Paths to New Nitride Materials
Formed by elements combining with nitrogen, nitrides can possess unique properties with potential applications from semiconductors to industrial coatings. But before nitrides can be put to use, they first must be discovered - and the odds of finding them in nature are slim. Now, your chances of discovering new nitrides just got better with a groundbreaking Nature Materials study led by Berkeley Lab in close collaboration with the National Renewable Energy Laboratory (NREL) and a number of other institutions.
