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, ...
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, ...
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 ...
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 ...
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 ...
An optimized method based on digitalized Lissajous curve to determine lifetime of luminescent materials on optical fiber sensors
(Hindawi, 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, ...
Fiber-based label-free D-dimer detection for early diagnosis of venous thromboembolism
(SPIE, 2020)
info:eu-repo/semantics/conferenceObject,
D-dimer is a useful diagnostic biomarker for deep vein thrombosis or pulmonary embolism, collectively referred to as venous thromboembolism (VTE). The ability to detect in real-time the amount of D-dimer with a fast and ...
