Structural transformation of vanadate nanotubes into vanadate oxides nanostructures during the dry reforming of methane
(2019-09-20)The metal-containing vanadate nanotubes namely MeVO-NT (Me=Ni, Co or Pt) were in situ transformed into vanadate oxides nanostructures i.e., MeVxOy, during the methane dry reforming. All the experimental observations through ... -
Superparamagnetic state in La0.7Sr0.3MnO3 thin films obtained by rf-sputtering
(2020-02-13)A novel superparamagnetic state has been observed in high quality La0.7Sr0.3MnO3 (LSMO) thin films directly grown by rf-sputtering on SiOx/Si(100) substrates. The films are nanostructured without grain boundaries, constituted ... -
Synergetic Application of Multi-Criteria Decision-Making Models to Credit Granting Decision Problems
(2019-11-22)Although various algorithms have widely been studied for bankruptcy and credit risk prediction, conclusions regarding the best performing method are divergent when using different performance assessment metrics. As a ... -
Synthesis, structural, and magnetic properties of Heusler-type Mn2-xFe1+xGe (0.0 ≤ x ≤ 1.0) alloys
(2021-07-21)Bulk Mn2-xFe1+xGe (0.0 ≤ x ≤ 1.0) alloys have been synthesized by arc-melting followed by a low temperature homogenization thermal annealing, whereas for comparison purposes the Mn2FeGe alloy was also produced in ribbon ... -
Target Field of View Prediction Using Artificial Pheromones for People Reidentification
(2019-12-10)People reidentification is a fundamental task in automated video surveillance based on computer vision. Reidentification happens when a person seen in a field of view is the same that has been observed in other fields of ... -
