Nitrogen fixation in ambient conditions

13-Nov-2018

Abundant in nature (78% of the air we breathe), nitrogen is rarely used in the industrial production of chemicals, with the most important process being the synthesis of ammonia, which is in turn used for the preparation of agricultural fertilizers. Using nitrogen as a raw material ("feedstock") ...

A burst of ”synchronous” light

Sandwich structure of nanocrystals as quantum light source

09-Nov-2018

Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This ...

Reinforcement of structures with Memory Steel

24-Oct-2018

So far, the steel reinforcements in concrete structures are mostly prestressed hydraulically. This requires ducts for guiding the tension cables, anchors for force transfer and oil-filled hydraulic jacks. The space requirements of all these apparatuses created the geometric framework conditions ...

Metal leads to the desired configuration

11-Oct-2018

Scientists at the University of Basel have found a way to change the spatial arrangement of bipyridine molecules on a surface. These potential components of dye-sensitized solar cells form complexes with metals and thereby alter their chemical conformation. Dye-sensitized solar cells have been ...

Eco-Friendly Nanoparticles for Artificial Photosynthesis

Quantum dots of indium phosphide and zinc sulfide using sunlight

02-Oct-2018

Researchers at the University of Zurich have developed a nanoparticle type for novel use in artificial photosynthesis by adding zinc sulfide on the surface of indium-based quantum dots. These quantum dots produce clean hydrogen fuel from water and sunlight – a sustainable source of energy. They ...
