Microgap thermophotovoltaic systems with low emission temperature and high electric output

open access: yes, 2015
We theoretically show that a thermophotovoltaic (TPV) system enhanced by a wire metamaterial opens the door to a prospective microgap thermophotovoltaics which will combine high electric output with relatively low temperatures of the emitter.

Sea-floor tectonics and submarine hydrothermal systems [PDF]

open access: yes, 2005
The discovery of metal-depositing hot springs on the sea floor, and especially their link to chemosynthetic life, was among the most compelling and significant scientific advances of the twentieth century. More than 300 sites of hydrothermal activity and

Exoplanets: Possible Biosignatures

open access: yes, 2017
The ancestor philosophers' dream of thousands of new worlds is finally realised: about 3500 extrasolar planets have been discovered in the neighborhood of our Sun. Most of them are very different from those we used to know in our Solar System.

Shock wave initiation of the Ti5Si3 reaction in elemental powders [PDF]

open access: yes, 1997
Elemental powder mixes were subjected to plane wave shock processing which reduced the initial porosity to essentially zero. Two powder mixes in a 5:3 Ti:Si atomic ratio were used: -325 mesh Ti and Si (

Animal emergence during Snowball Earths by thermosynthesis in submarine hydrothermal vents [PDF]

open access: yes, 2009
Darwin already commented on the lateness in the fossil record of the emergence of the animals, calling it a valid argument against his theory of evolution^1^.

Unification and Planning of Urban Public Spaces With Bioclimatic Conditions. Case Study Drama, Greece [PDF]

open access: yes
The green spaces in the urban environment facilitate the movement of air masses that act as air refreshment in the wider region. The unification of urban open spaces and their enrichment with vegetation affect the micro-climate positively and act as a ...
