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, ...
Optical fiber sensors based on nanoparticle-embedded coatings
(Hindawi Publishing Corporation, 2015)
Artículo / Artikulua,
The use of nanoparticles (NPs) in scientific applications has attracted the attention of many researchers in the last few years. The use of NPs can help researchers to tune the physical characteristics of the sensing coating ...
Nanomaterials for functional textiles and fibers
(Springer US, 2015)
Artículo / Artikulua,
Nanoparticles are very interesting because of their surface properties, different from bulk materials. Such properties
make possible to endow ordinary products with new functionalities. Their relatively low cost with ...
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 ...
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 ...
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 ...
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 ...
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 ...
Effect of both protective and reducing agents in the synthesis of multicolor silver nanoparticles
(Springer, 2013)
Artículo / Artikulua,
In this paper, the influence of variable molar ratios between reducing and loading agents (1:100, 1:50, 1:20, 1:10, 1:5, 1:2, 1:1, 2:1) and between protective and loading agents (0.3:1, 0.75:1, 1.5:1, 3:1, 7.5:1, 30:1, ...
An optimized method based on digitalized Lissajous curve to determine lifetime of luminescent materials on optical fiber sensors
(Hindawi Publishing Corporation, 2016)
Artículo / Artikulua,
A method is proposed to determine lifetime of luminescent emissions based on the phase shift measurement employing the digitalized Lissajous representation: this diagram has been typically used with analogical algorithms, ...
