An antibacterial coating based on a polymer/sol-gel hybrid matrix loaded with silver nanoparticles
(Springer, 2011)
Artículo / Artikulua,
In this work a novel antibacterial surface composed of an organic-inorganic hybrid matrix of tetraorthosilicate and a polyelectrolyte is presented. A precursor solution of tetraethoxysilane (TEOS) and poly(acrylic acid ...
Enabling personal privacy for pervasive computing environments
(Graz University of Technology, IICM, 2010)
Artículo / Artikulua,
Protection of personal data in the Internet is already a challenge today. Users have to
actively look up privacy policies of websites and decide whether they can live with the terms of
use. Once discovered, they are ...
Multicolor layer-by-layer films using weak polyelectrolyte assisted synthesis of silver nanoparticles
(Springer, 2013)
Artículo / Artikulua,
In the present study, we show that silver nanoparticles (AgNPs) with different shape, aggregation state and color (violet, green, orange) have been successfully incorporated into polyelectrolyte multilayer thin films using ...
Sensitivity improvement of a humidity sensor based on silica nanospheres on a long-period fiber grating
(MDPI, 2009)
Artículo / Artikulua,
This work addresses a new configuration that improves the sensitivity of a humidity sensor based on a long-period fiber grating coated with a SiO(2)-nanospheres film. An intermediate higher refractive index overlay, ...
Volatile organic compound optical fiber sensors: a review
(MDPI, 2006)
Artículo / Artikulua,
Volatile organic compound (VOC) detection is a topic of growing interest with applications in diverse fields, ranging from environmental uses to the food or chemical industries. Optical fiber VOC sensors offering new and ...
Pyridine vapors detection by an optical fibre sensor
(MDPI, 2008)
Artículo / Artikulua,
An optical fibre sensor has been implemented towards pyridine vapors detection; to achieve this, a novel vapochromic material has been used, which, in solid state, suffers a change in colour from blue to pink-white in ...
Development of an in-fiber nanocavity towards detection of volatile organic gases
(MDPI, 2006)
Artículo / Artikulua,
A fiber optic sensor for Volatile Organic Compounds (VOCs) detection has been developed and characterized for some organic gasses. The sensor is based on a novel vapochromic material, which is able to change its optical ...
A comparative study of two different approaches for the incorporation of silver nanoparticles into layer-by-layer films
(Springer, 2014)
info:eu-repo/semantics/article,
In this work, a comparative study about the incorporation of silver nanoparticles (AgNPs) into thin films is presented
using two alternative methods, the in situ synthesis process and the layer-by-layer embedding deposition ...
Comparative study of layer-by-layer deposition techniques for poly(sodium phosphate) and poly (allylamine hydrochloride)
(Springer, 2013)
info:eu-repo/semantics/article,
An inorganic short chain polymer, poly(sodium phosphate), PSP, together with poly(allylamine hydrochloride), PAH,
is used to fabricate layer-by-layer (LbL) films. The thickness, roughness, contact angle, and optical ...
