Thermodynamics of the Formation of Ti- and Cr-doped CuGaS2 Intermediate-band Photovoltaic Materials

We describe the exfoliation of these materials and the formation of stable suspensions in water, suitable to interact and detect a variety of potential water contaminants such as

The draft amendments do not operate any more a distinction between different states of emergency; they repeal articles 120, 121and 122 and make it possible for the President to

H I is the incident wave height, T z is the mean wave period, Ir is the Iribarren number or surf similarity parameter, h is the water depth at the toe of the structure, Ru is the

Astrometric and photometric star cata- logues derived from the ESA HIPPARCOS Space Astrometry Mission.

In the previous sections we have shown how astronomical alignments and solar hierophanies – with a common interest in the solstices − were substantiated in the

Then, according to the free energy profiles, and considering the relative energies of the reactant states discussed above, the most favourable redox mechanism of the

Given the much higher efficiencies for solar H 2 -generation from water achieved at tandem PEC/PV devices ( > 10% solar-to-H 2 energy efficiency under simulated sunlight) compared

As we have seen, even though the addition of a cosmological constant to Einstein’s eld equations may be the simplest way to obtain acceleration, it has its caveats. For this rea-
