Comparison of Ground- and Space-based Longitudinal Magnetograms

, 2012
We compare photospheric line-of-sight magnetograms from the Synoptic Long-term Investigations of the Sun (SOLIS) vector spectromagnetograph (VSM) instrument with observations from the 150-foot Solar Tower at Mt.

Simulation of an absorption based solar cooling facility using a geothermal sink for heat rejection [PDF]

, 2008
An important issue of solar cooling facilities based on absorption cycles and sometimes not given the necessary attention is the recooling process of the absorber and condenser.

Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

Advanced Functional Materials, EarlyView.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...

Passive solar reflector satellite revisited [PDF]

, 1980
Passive light weight reflectors in space which direct the incident solar energy to a specified location on the Earth surface are proposed as an alternative system for the solar power satellite to overcome conversion losses and to avoid the need for ...

Impact of solar tower design parameters on sCO2-based solar tower plants

, 2018
Integrating high efficiency sCO2 power cycles into solar tower plants is characterized by high upper temperature and low temperature spread of the cycle working fluid sCO2. New heat transfer media (HTM) are required, enabling higher temperatures and low cost storage.

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Sustainable solar energy potential on marine passenger ships of Bay of Bengal: A way of reducing carbon dioxide emissions and disaster risk reduction

Energy Exploration & Exploitation, 2023
In Bangladesh, there are roughly 31 marine passenger ships that are in operation. These ships might be a good location for solar photovoltaic (PV) plants since solar energy is the best renewable energy to replace the fossil fuel used in the ships.
