Solvent Effect on Morphology and Optical Properties of Poly(3-hexylthiophene):TIPS-Pentacene Blends
(2018-02-01)
Optical, electrical, and morphological properties of poly(3-hexylthiophene):6,13-bis(triisopropylsilylethynyl) (TIPS)-pentacene (P3HT:TP) blend films, in the proportion of 1:1 (w/w), have been investigated using chloroform, ...
Tailoring of phase-segregation structures in two-soft-segment urethane/urea polymer membranes
(John Wiley & Sons IncHobokenEUA, 2007)
Phase separation and segregation morphology of PCL/PS blends: quantitative effect of the crystallization temperature, composition and molecular weight of PS
(Wiley, 2016-11-21)
The phase diagrams for blends of semicrystalline poly(ecaprolactone)(PCL) with amorphous polystyrene (PS) were determined and it was noticed that when molecular weight increases, the critical composition diminishes while ...
Modeling of macrosegregation and microporosity formation during transient directional solidification of aluminum alloys

Segregation of phenotypic characteristics in hybrids of Triatoma brasiliensis species complex (Hemiptera, Reduviidae, Triatominae)
(2021-07-01)
There are currently 156 species, grouped into 18 genera and five tribes included in the subfamily Triatominae. All of them are potential vectors of Chagas disease. Triatoma is paraphyletic and the species of this genus ...
Electric field-modified segregation in crystal fibers of colossal magnetoresistive 'La IND.0.7''Ca IND.0.3'Mn'O IND.3'
(Amsterdam, 2008-07)
Manganites are materials with a high potential for applications in magnetic sensors, head-reading magnetoresistives hard disk, RAM memories and actuator devices, among others. Laser heated floating zone (LHFZ) growth of ...
Morphofunctional and geographic segregation among species of lasiurine bats (Chiroptera: Vespertilionidae) from the South American Southern Cone
(De Gruyter, 2011-05)
Four morphologically similar species of insectivorous bats in the genus Lasiurus (Chiroptera: Vespertilionidae) regularly occur in the American Southern Cone. Three of them (Lasiurus cinereus, L. blossevillii and L. ega) ...
Delimitation of the Segregate Genera of Maytenus s. l. (Celastraceae) Based on Morphological and Molecular Characters
(Amer Soc Plant Taxonomists, 2011-10-01)
Maytenus s. l. (including Gymnosporia) is a morphologically diverse genus of about 300 species that is widely distributed in the tropics and subtropics of both the Old and New Worlds. Its delimitation has been extensively ...
Ecomorphology of the African felid ensemble: the role of the skull and postcranium in determining species segregation and assembling history
(Wiley, 2013-01)
Morphology of extant felids is regarded as highly conservative. Most previous studies have focussed on skull morphology, so a vacuum exists about morphofunctional variation in postcranium and its role in structuring ensembles ...
Morphological divergences as drivers of diet segregation between two sympatric species of Serrapinnus (Characidae: Cheirodontinae) in macrophyte stands in a neotropical floodplain lake
(2021-01-01)
Diet and morphology of Serrapinnus notomelas and Serrapinnus sp.1 were investigated across ontogeny, as a way to elucidate the key elements linked to the resource partitioning (a main driver for species coexistence). Fish ...
