Influência dos parâmetros de síntese nas características morfológicas de microcápsulas de poli(ureia-formaldeído) para uso em sistemas de autorreparo
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE MATERIAIS, 2017-12-13)
Self-healing materials are a class of smart materials with an inherent ability to repair damage,
thus recovering their functionality. Urea-formaldehyde microcapsules have been studied to
provide self-healing functionality ...
The effect of liposome-delivered prednisolone on collagen density, myofibroblasts, and fibrous capsule thickness around silicone breast implants in rats
(Wiley-Blackwell, 2010-07-01)
Capsular contracture is a potential adverse effect of breast implants. An inflammatory reaction is most likely the origin of fibrosis around the implant. It is possible that some substances may act to prevent this inflammatory ...
Impacto financiero de la creación del impuesto a la salida de divisas y la disminución gradual del impuesto a la renta, en las Empresas del Sector Atunero. Durante el periodo 2008-2012
(Universidad de Guayaquil, Facultad de Ciencia Administrativas, 2013)
El Gobierno ecuatoriano, en un intento por fomentar la inversión local y disminuir la salida de capitales, creó una tasa impositiva que grava la salida de divisas de nuestro país. El Impuesto a la Salida de divisas es un ...

Opposition MP’s in Grenada walked out of the island’s parliament during a debate of a motion of no confidence against Prime Minister Keith Mitchell’s, New National Party. Next, a Cuban/American drug smuggler has told ...
Stimulation of Cysteine-Coated CdSe/ZnS Quantum Dot Luminescence by meso-Tetrakis (p-sulfonato-phenyl) Porphyrin
(BioMed Central, 2018)
Abstract
Interaction between porphyrins and quantum dots (QD) via energy and/or charge transfer is usually accompanied by reduction of the QD luminescence intensity and lifetime. However, for CdSe/ZnS-Cys ...
Transplant bioassay induces different imposex responses in two species of the genus Stramonita
(Taylor & Francis, 2012-02-14)
A bioassay to study differential specific responses in imposex development due to marine organotin pollution was done by transplanting specimens of the gastropods Stramonita haemastoma and Stramonita rustica from an ...
Síntese de microcápsulas de poli(ureia formaldeído)/ENB e avaliação do mecanismo de autorreparo em resina epóxi.
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Materiais, 2019-12-02)
The necessity of repairing damages in engineering materials caught the attention of several researchers to seek inspiration in natural self-healing mechanisms, and develop similar systems, capable of recover cracks in ...
Collagen-silica nanocomposites as dermal dressings preventing infection in vivo
(Elsevier Science, 2018-12)
The controlled delivery of multiple drugs from biomaterials is a timely challenge. In particular the nanocomposite approach offers a unique opportunity to combine the scaffold-forming ability and biocompatibility of hydrogels ...
