Escape depth of secondary electrons from electron-irradiated polymers
(1992-08-01)
Measurements on polymers (Teflon FEP and Mylar) have shown that the secondary electron emission from uncharged surfaces exceeds that from surfaces containing a positive surface charge. The reduced emission of charged ...
Dielectric behaviour of CaCu3Ti4O12-epoxy composites
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2008-01-01)
The dielectric behavior of composite materials (epoxy resin - barium titanate and epoxy - CCTO) was analysed as a function of ceramic amount. Composites were prepared by mixing the components and pouring them into suitable ...
Morphological modifications and surface amorphization in ZnO sonochemically treated nanoparticles
(2013-05-01)
Application of nanoscale materials in photovoltaic and photocatalysis devices and photosensors are dramatically affected by surface morphology of nanoparticles, which plays a fundamental role in the understanding of the ...
Molecular design of new P3HT derivatives: Adjusting electronic energy levels for blends with PCBM
(Elsevier B.V., 2014-12-15)
An intensive search is underway for new materials to make more efficient organic solar cells through improvements in thin film morphology, transport properties, and adjustments to the energy of frontier electronic levels. ...
Efectos de la radiación en las propiedades eléctricas del grafeno : estados topológicos de Floquet inducidos por láser
(2015-12)
Esta tesis está dedicada al estudio teórico del grafeno iluminado por un láser intenso. Nos enfocamos en efectos no perturbativos de la luz sobre el material, utilizando la teoría de Floquet. Mostramos cómo un láser puede ...
Enhanced Hydrophobicity in Nanocellulose-Based Materials: Toward Green Wearable Devices
(2021-09-20)
Nanocellulose is a promising material for fabricating green, biocompatible, flexible, and foldable devices. One of the main issues of using nanocellulose as a fundamental component for wearable electronics is the influence ...
