The modulation of the electronic structure of cobalt islands on Cu(111) by the Moire pattern of an Ag overlayer is investigated. Acquisition of tunneling spectroscopy maps reveals a local modification of both the energy and the amplitude of the cobalt-rela ...
Thermal soaring saves much energy, but flying large distances in this form represents a great challenge for birds, people and unmanned aerial vehicles (UAVs). The solution is to make use of the so-called thermals, which are localized, warmer regions in the ...
Water and energy are the key resources required for both economic and population growth, and yet both are increasingly scarce. The distribution of water takes large amounts of energy, while the production of energy requires large amounts of water in proces ...
The intention of a single energy market in Europe is to have a sustainable, competitive, and secure supply of energy. However, the current rise in the cost of electricity supply is affecting the competitiveness of large industrial users. This has led large ...
An innovative subway has been proposed using supercapacitors as energy source. In this paper, are presented different possibilities to reduce on-board stored energy in order to downsize the on-board energy storage subsystem. Special attention is paid to th ...
Even if supercapacitors present a reduced energy density, they allow to store a significant amount of energy which leads to a significant autonomy for applications with reduced energy needs. The main advantage of supercapacitors is to compensate a limited ...
This study contrasts the implantation of 25 μm thick Polydimethylsiloxane (PDMS) membranes with titanium and gold ions at 10 keV and 35 keV for doses from 1x10^15 at/cm2 to 2.5x10^16 at/cm2 implanted with two different techniques: Filtered Cathodic Vacuum ...
Researchers from Switzerland and Morocco undertook a joint project to develop a technique for producing electrical energy from renewable primary energy sources to supply small networks of isolated consumers. Specific attention was paid to sustainable devel ...
We report on a simple method for enhancing the efficiency of photoluminescence (PL) emission from selected chiral forms of semiconducting single-wall carbon nanotubes (SWCNTs). The method is based on the use of a fluorescent dye (Nile blue A) that shows th ...
The emergence of new big consumer countries on the energy markets and the perspective of oil and gas depletion at the end of the current century raise the concerns about fair distribution of the remaining resources for the common and sustainable wellbeing ...
