Enhancement of symmetry-induced photoluminescence in bismuth tungstate microcrystals
(2016-12-01)
Bi2WO6 (BWO) powders synthesized via hydrothermal processes were studied in order to determine the effect of structure on photoluminescence (PL). BWO samples were characterized using X-Ray Powder Diffraction, UV–vis diffuse ...
Beyond the Mohring effect: scale economies induced by transit lines structures design
(Elsevier, 2020)
In this paper we study how the spatial arrangement of transit lines (lines structure) influences scale economies in public transport. First we show that the degree of scale economies (DSE) increases discretely whenever ...
Changing of the spontaneous polarization in niobate nanoparticles induced by non isovalent doping
(2015-01-01)
Ferroelectric niobates with tetragonal tungsten bronze TTB-type structure have shown great technology interest for application in pyroelectric detectors and piezoelectric transducers, sensor/filter in composite. The synthesis ...
Characterization of the temperature, load and damage effects using piezoelectric transducer patches based on fuzzy clustering
(2011-12-01)
Structural Health Monitoring (SHM) denotes a system with the ability to detect and interpret adverse changes in a structure. One of the critical challenges for practical implementation of SHM system is the ability to detect ...
Photo-induced birefringence and surface ripples structures in As-S-Ag chalcogenide thin-films
(2019-09-01)
Photo-induced phenomena are investigated in new metastable Agx(As20S80)100-x chalcogenide thin-films prepared by the co-evaporation technique. Under irradiation using an Ar laser at 488 nm, periodic ripples structures ...
Changes in vegetation structure induced by domestic grazing in Patagonia (Southern Argentina)
(Academic Press Ltd - Elsevier Science Ltd, 2011-11)
We analyzed the structural differences associated with grazing exclusion on vegetation by studying 24 grazed-ungrazed paired sites in Patagonia (Argentina). Our objectives were to evaluate the effect of grazing on plant ...
Role of acidic and basic electrolytes on the structure and morphology of cathodically reduced indium tin oxide (ITO) substrates
(2013-09-23)
In this report we track the structural changes suffered by ITO along galvanostatic polarization at different current densities by X-ray diffraction and SEM micrographs. The XRD shown that cathodic treatment induces structural ...
