Hierarchy of hybrid materials, part-II : the place of organics-on-inorganics in it, their composition and applications Ghent University
Hybrid materials or hybrids incorporating organic and inorganic constituents are emerging as a very potent and promising class of materials due to the diverse but complementary nature of their properties. This complementarity leads to a perfect synergy of properties of the desired materials and products as well as to an extensive range of their application areas. Recently, we have overviewed and classified hybrid materials describing ...
A hybrid thermal management system for high power lithium-ion capacitors combining heat pipe with phase change materials Vrije Universiteit Brussel
Lithium-ion capacitor (LiC) technology is an energy storage system (ESS) that combines the working mechanism of electric double-layer capacitors (EDLC) and lithium-ion batteries (LiB). When LiC is supposed to work under high power applications, the inevitable heat loss threatens the cell's performance and lifetime. Therefore, a proper thermal management system (TMS) can remove the generated heat of the LiC during high cycling conditions. In this ...
Temperature dependent NIR emitting lanthanide-PMO/silica hybrid materials KU Leuven Ghent University
Two materials - a mesoporous silica (MS) and a periodic mesoporous organosilica (PMO) functionalized with dipyridyl-pyridazine (dppz) units were grafted with near-infrared (NIR) emitting lanthanide (Nd3+, Er3+, Yb3+) complexes in an attempt to obtain hybrid NIR emitting materials. The parent materials: dppz-vSilica and dppz-ePMO were prepared by a hetero Diels-Alder reaction between 3,6-di(2-pyridyl)-1,2,4,5-tetrazine (dptz) and the double bonds ...
Hierarchy of hybrid materials : the place of inorganics-in-organics in it, their composition and applications Ghent University
Hybrid materials, or hybrids incorporating both organic and inorganic constituents, are emerging as a very potent and promising class of materials due to the diverse, but complementary nature of the properties inherent of these different classes of materials. The complementarity leads to a perfect synergy of properties of desired material and eventually an end-product. The diversity of resultant properties and materials used in the construction ...
Winding loss suppression in inverter-fed traction motors via hybrid coil materials and configurations Ghent University
In a typical inverter-fed AC drive system, the stator windings carry a current with a large harmonics content, resulting in an increased AC loss. In this paper, the additional copper losses caused by non-sinusoidal currents are investigated for different magnet wire topologies, including the flat conductor, stranded, and litz wires. Also, a two-slot simplified model is introduced for accurate prediction of the AC losses at high frequency. It is ...
Exploiting mono‐ and hybrid nanocomposite materials for fused filament fabrication with acrylonitrile butadiene styrene as polymer matrix Ghent University
Acrylonitrile butadiene styrene (ABS) based polymeric composites consisting of mono- and hybrid nano-compounds, that is, graphene nanoplatelets (GNP's), multi-walled carbon nanotubes (CNT's), and titanium dioxide (TiO2), are studied for fused filament fabrication (FFF). Rheological analysis in a screening step reveals that nanocomposites containing CNT result in a better nano-filler dispersion within the matrix and enhanced matrix interaction. ...
Fibre engineered cementitious materials (FECM) optimization by the use of hybrid polypropylene fibres and supplementary powder addition Ghent University
Development of Fibre Engineered Cementitious Materials with Self-Healing Capacity (SH-FECM) was an important goal of the recent research programmes conducted in NIRD URBAN-INCERC Cluj-Napoca Branch. Several theoretical and experimental studies were performed in order to improve the composites, considering both, fresh and hardened state properties and also the performance as filling material of the narrow spaces at the beam to column interface ...
