Solar Thermal Panels: Black is Back!
Solar Thermal Panels: Black is Back!
Solar thermal panels developed at EPFL are are dressed up in unique and patented new materials. Researchers created a stronger black coating that retains its original color and thereby its absorption properties much longer than traditional panels. Like most elements of a building, the lifespan of a solar thermal panel is between 25 and 30 years.

Graphene nanoribbons for "reading" DNA
One of the methods used for examining the molecules in a liquid consists in passing the fluid through a nano-sized hole so as to detect their passage. EPFL researchers have found a way to improve this technique by using a material with unique properties: graphene. If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile.

Imaging fluctuations with X-ray microscopy
Media Releases X-rays allow an inside look at structures that cannot be imaged using visible light. They are used to investigate nanoscale structures of objects as varied as single cells or magnetic storage media. Yet, high-resolution images impose extreme constraints on both the X ray microscope and the samples under investigation.

New Insights into Superconducting Materials
New Insights into Superconducting Materials
An American-Swiss research team has used a new X-ray technique at Swiss Light Source (SLS) of the Paul Scherrer Institute (PSI) to investigate the magnetic properties of atomically thin layers of a parent compound of a high-temperature superconductor. It turns out that the magnetic properties of such thin films differ by only a surprisingly small degree from those of macroscopically thick samples.

Physicists observe the splitting of an electron inside a solid
An electron has been observed to decay into two separate parts, each carrying a particular property of the electron: a spinon carrying its spin – the property making the electron behave as a tiny compass needle – and an orbiton carrying its orbital moment – which arises from the electron's motion around the nucleus.

Researchers Find Universal Law For Material Evolution
Researchers Find Universal Law For Material Evolution
Many important materials are composed of several phases – regions that differ in structure or chemical composition. When such a material is heated, atoms move from one phase to another, which changes the distribution of the phases – and thus, the properties of the material.

Understanding plastic semiconductors better
Semiconductors made from polymer materials are becoming increasingly important for the electronics industry – as a basis for transistors, solar cells or LEDs – showing important advantages when compared to conventional materials: they are lightweight, flexible and very cheap to produce. Usually, they consist of more than one substance as they get their particular electric properties only when several materials are blended.
