The observation of biological processes in their native environments is of critical importance for life science. While substantial information can be derived from the examination of in-vitro biological samples, in-vivo ...
The last two decades have been a very fruitful period for the fundamental research related to quantum information theory. Today we have a fairly good understanding of how intrinsically quantum properties affect various ...
The device-independent formalism is a set of tools to analyze experimental data and infer properties about systems, while avoiding almost any assumption about the functioning of devices. It has found applications both in ...
The study of the brain using diffuse optical methods has progressed rapidly in the recent years. The possibility of studying the cerebral microvasculature in addition to the portability and low cost of these devices, opens ...
Since the pioneering work of Fujishima and Honda on titanium dioxide, TiO2, for the electrochemical photolysis of water under ultraviolet (UV) irradiation, semiconductor-based photocatalysis and photovoltaics have become ...
Solution-processed thin film solar cells emerged as very promising photovoltaic technologies suitable for a low cost roll-to-roll upscale production. Such thin film character also ensures lightweight and flexibility for ...
Nanotechnology was named one of the key enabling technologies by the European Commission and its tremendous impact was envisioned early by 20th century physicist R.Feynman in his now oft-quoted talk "Plenty of Room at the ...
At sufficiently low temperatures, fluids of bosonic particles may undergo a phase transition, below which a Bose-Einstein condensate (BEC) forms. The BEC is one of the most fundamental concepts in many-body quantum physics ...
