Optimum heat treatment to enhance the weak-link response of Y123 nanowires prepared by Solution Blow Spinning
(2021-02-01)
Although the production of YBa2Cu3O7-δ (Y123) has been extensively reported, there is still a lack of information on the ideal heat treatment to produce this material in the form of one dimension nanostructures. Thus, by ...
Influence of titanium precursor on photoluminescent emission of micro-cube-shaped CaTiO3
(Elsevier B.V., 2015-09-01)
For this research, we studied the influence of titanium tetrachloride (TC) and titanium tetraisopropoxide (TTP) precursors on CaTiO3 (CTO) synthesis by employing a microwave-assisted hydrothermal (MAH) method regarding ...
Tropical lotic primary producers: Who has the most efficient photosynthesis in low-order stream ecosystems?
(2017-09-01)
Photosynthetic performance was assessed for the main groups of primary producers of low-order tropical streams, comprising macroalgae (11 taxa of Chlorophyta, Rhodophyta and Xanthophyta plus Cyanobacteria), bryophytes (2), ...
Fingerprint of semi-crystalline structure memory in the thermal and ionic conduction properties of amorphous ureasil-polyether hybrid solid electrolytes
(2022-02-04)
Correlations among the structure, thermal properties, and ionic conductivity of solid polymer electrolytes (SPEs) were studied using a ureasil-polyethylene oxide (U-PEO) organic-inorganic hybrid prepared according to a ...
Goldilocks at the dawn of complex life: mountains might have damaged Ediacaran–Cambrian ecosystems and prompted an early Cambrian greenhouse world
(2021-12-01)
We combine U–Pb in-situ carbonate dating, elemental and isotope constraints to calibrate the synergy of integrated mountain-basin evolution in western Gondwana. We show that deposition of the Bambuí Group coincides with ...
Anestesia para separação de gêmeos isquiópagos no período neonatal. Relato de caso
(2002-08-14)
Background and Objectives - The separation of conjoined twins has always raised considerable interest because of surgical and anesthetic complexity, pathology rarity and few survival chances. The goal of this description ...

Water-stress-induced thermotolerance of photosynthesis in bean (Phaseolus vulgaris L.) plants: The possible involvement of lipid composition and xanthophyll cycle pigments
(Elsevier, 2012)
A common feature in plants that are exposed to gradual stressful environmental factors is the development
of a level of resistance to such constraints, which sometimes protects against different stressful
environmental ...
Neumomediastino espontáneo (síndrome de Hamman): Una enfermedad benigna mal diagnosticada
(Sociedad Médica de Santiago, 2009)
Background: Hamman syndrome or spontaneous pneumomediastinum is uncommon and its clinical manifestations are chest pain, dyspnea and subcutaneous emphysema. Aim: To report a series of patients with spontaneous pneumomediastinum. ...
