Naturally occurring photosynthetic systems in plants are supported by elaborate pathways of self-repair that limit the impact of photo-damage. Herein, we demonstrate a complex consisting of two recombinant proteins, phospholipids and a carbon nanotube that ...
In the present paper, a model of a solar tower power plant (STPP) is presented. This is the result of a Master semester project led at the Laboratory for Industrial Energetic Systems (LENI) at the Swiss Federal Institute in Lausanne (EPFL). The modelized p ...
The integration of steam cycles in the power plant industry aims at optimizing the conversion of the available heat into mechanical power. The proposed method uses process integration techniques and a multi-objective optimisation procedure to generate opti ...

This paper presents a study of a residential (about 20kW) ORC-ORC (Organic Rankine Cycle) thermally driven heat pump. The system works with three different temperature levels similar to absorption heat pumps. The proposed concept is a hermetic system using ...
The advanced fast reactors of the fourth generation should be capable to breed their own fuel from poorly fissile 238U and to recycle the actinides from their own spent fuel. However, this recycling or actually the closure of fuel cycle has negative impact ...
To be profitable, a geothermal energy system must effectively and economically convert a given resource into useful energy services to be delivered to the consumer during different periods of the year. These services include electricity, district heating, ...
New saturated critical heat flux (CHF) data have been obtained experimentally in two different multi-microchannel heat sinks made in copper with three low pressure refrigerants (R134a, R236fa, R245fa). One of the test sections had 20 parallel rectangular c ...
As our awareness of the dangers of global climate change grows, the development of new renewable energy technologies is of primary importance in the effort to reduce emissions of carbon dioxide and other greenhouse gases. Rapid increases in the price of oi ...
A constructaltree-shaped microchannel network for maximizing the saturated critical heat flux in a disc-shaped planar body has been investigated. n(0) radial channels touch the center and n(p) channels touch the periphery. Designs with no pairing level (n( ...
The application of flow boiling in microchannels in copper cooling elements for very high heat flux dissipation from microprocessor chips is one of the promising technologies to replace air cooling and water cooling of these units, particularly in mainfram ...
