Abstract : The main role of electrocatalysts is to bring a redox potential at the electrode surface as close as possible to the equilibrium potential of the reaction of interest. It has been considered that alloying is one of the […]
Abstract : Learning from the concepts used by green plants photosynthesis, we have developed nanostructured systems affording efficient solar light harvesting and conversion to electricity and fuels. Solar cells using dyes or semiconducting nano-particles as light harvesters supported by mesoscopic […]
Abstract : Many current products and systems employ sophisticated mathematical algorithms to automatically make complex decisions, or take action, in real-time. Examples include recommendation engines, search engines, spam filters, on-line advertising systems, fraud detection systems, automated trading engines, revenue management […]
Abstract : With the improvements in medicine in the last few decades, people are living longer, but with multiple, often complex, health conditions. From an epidemiological standpoint, the cohort of “baby boomers” in the developed countries is now reaching an […]
Abstract : Intermetallic systems with 4f or 5f electrons have often interesting thermodynamic properties at low temperatures. They behave like metals with very heavy charge carriers, i.e., their masses can be several hundred times the free electron mass. However, the […]
Abstract : Thermodynamics is the discipline of energy and provides the foundations for the various aspects of energy conversion to useful work. In spite of the close connection between energy and thermodynamics, this topic is often not given enough attention. […]
Abstract : Growing number of synaptic proteins are being associated with various brain diseases including schizophrenia, autism, and attention deficit hyperactivity disorder (ADHD). ADHD is a psychiatric disorder that affects ~5% of school-aged children; however, the mechanisms underlying ADHD remain […]

Abstract : The feed-in tariffs in several European markets until 2010 had led to an overly optimistic expectations on the global PV demand, and currently there is a severe disparity between the supply and the demand. The aggressive production capacity […]
