How can robots land like birds?
Birds can perch on a wide variety of surfaces, thick or thin, rough or slick. But can they find stable footing if a branch is covered in Teflon? In the interest of making better robots, Stanford researchers found out. Under the watchful eyes of five high-speed cameras, a small, pale-blue bird named Gary waits for the signal to fly.

Five cool things our surface scientists do
Surface science can make a big difference to our health, well-being and environment. Our surface scientists at Durham have been working on a whole range of applications that have already changed our lives in some way (think mobile phones and puddles) and could make a real difference to people around the world, particularly in developing countries.

Lessons of conventional imaging let scientists see around corners
UW graduate students (left to right) Xiaochun Liu, Ji-Hyun Nam and Toan Le work with assistant professor and principal investigator Andreas Velten (right) in the Computational Optics lab. Their project is designed to create non-line-of-sight images using reflected laser light. Photo: Bryce Richter Along with flying and invisibility, high on the list of every child's aspirational superpowers is the ability to see through or around walls or other visual obstacles.

From Japanese basket weaving art to nanotechnology with ion beams
Ultradense arrays of magnetic quanta in high-temperature superconductors The properties of high-temperature superconductors can be tailored by the introduction of artificial defects. An international research team around physicist Wolfgang Lang at the University of Vienna has succeeded in producing the world's densest complex nano arrays for anchoring flux quanta, the fluxons.

Generating energy from wastewater
A new battery made from affordable and durable materials generates energy from places where salt and fresh waters mingle. The technology could make coastal wastewater treatment plants energy-independent and carbon neutral. Salt is power. It might sound like alchemy, but the energy in places where salty ocean water and freshwater mingle could provide a massive source of renewable power.

Unravelling corrosion
Unravelling corrosion
ETH researchers have succeeded in elucidating how and at what rate steel corrodes in a variety of porous materials. Their findings help enable the breakthrough of new, environmentally friendly types of cement. The rate at which steel corrodes in concrete or other porous materials is crucial to a large number of technological applications, such as underground pipelines or steel-reinforced concrete bridges.

Crystal With a Twist: Scientists Grow Spiraling New Material
With a simple twist of the fingers, one can create a beautiful spiral from a deck of cards. In the same way, scientists at Berkeley Lab and UC Berkeley have created new inorganic crystals made of stacks of atomically thin sheets that unexpectedly spiral like a nanoscale card deck. Their surprising structures, reported in a  new study  in the journal Nature, may yield unique optical, electronic and thermal properties, including superconductivity, the researchers say.

Yellow is not the new black: discovery paves way for new generation of solar cells
Yellow is not the new black: discovery paves way for new generation of solar cells
By stabilizing perovskites -man-made crystals that can convert sunlight into electricity- they absorb sunlight and can be used in efficient solar panels. Perovskites are semiconductor materials that have many applications. They show particular promise in harvesting solar energy. Currently, most solar cells are made with silicon crystals, a relatively straightforward and effective material to process for this purpose.

Yellow is not the new black: discovery paves way for new generation of solar cells
A study led by KU Leuven for the first time explains how a promising type of perovskites - man-made crystals that can convert sunlight into electricity - can be stabilised. As a result, the crystals turn black, enabling them to absorb sunlight. This is necessary to be able to use them in new solar panels that are easy to make and highly efficient.

Developing technologies that run on light
Researchers are designing a nanoscale photon diode - a necessary component that could bring us closer to faster, more energy-efficient computers and communications that replace electricity with light. The future of faster, more efficient information processing may come down to light rather than electricity.

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
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.

Physicists find first possible 3D quantum spin liquid
Cerium pyrochlore is first to qualify as long-sought state of matter There's no known way to prove a three-dimensional "quantum spin liquid” exists, so Rice University physicists and their collaborators did the next best thing: They showed their single crystals of cerium zirconium pyrochlore had the right stuff to qualify as the first possible 3D version of the long-sought state of matter.

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
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.
