Magnetocaloric effect with very small magnetic hysteresis losses of CoMn1-xTixGe Alloys
(SpringerSpringer, 2017)
The effects of Ti substitution for Mn and heat treatment on structural, magnetic, and magnetocaloric properties of CoMnGe alloy have been investigated using electron microscopy, X-ray diffraction, calorimetric, and magnetic ...
A biochar-modified carbon paste electrode
(2017)
The present work examıned the use of biochar derived from tea waste as a novel electrode material. For the fabrication of the biochar electrode, suitable amounts of biochar and graphite were mixed with mineral oil for the ...
Performance assessment of a novel hybrid district energy system
(Pergamon-Elsevier Science Ltd, 2012)
In this paper, a new hybrid system for improving the efficiency of geothermal district heating systems (GDHSs) is proposed. This hybrid system consists of biogas based electricity production and a water-to-water geothermal ...
A novel approach for estimation of photovoltaic exergy efficiency
(Pergamon-Elsevier Science Ltd, 2012)
In this study, a novel approach is proposed to determine the maximum amount of exergy from the sun when applied to a conventional photovoltaic (PV) system in order to formulate its exergy efficiency. the variations of ...
Investigation of a hybrid solar and geothermal driven absorption cooling system for district applications
(Inderscience Enterprises Ltd, 2012)
In this paper, a new hybrid geothermal and solar driven absorption cooling system (ACS) is proposed for low-temperature district energy applications. Two approaches are proposed in this study, namely: (a) a new model for ...
Inverse magnetocaloric effect of epitaxial Ni-Mn-Sn thin films
(Amer Inst Physics, 2013)
Epitaxial Ni-Mn-Sn thin films of 200 nm thickness were prepared by magnetron sputtering and deposited onto MgO(100) substrate. They reveal an inverse magnetocaloric effect with a martensitic phase transition around 260 K. ...
