All-Silicon spherical-Mie-resonator photodiode with spectral response in the infrared region

Garín Escrivá, Moisés; Fenollosa Esteve, Roberto; Alcubilla, Ramón; Shi, Lei; Marsal, L. F.; Meseguer Rico, Francisco Javier (Nature Publishing Group, 2014-03)

[EN] Silicon is the material of choice for visible light photodetection and solar cell fabrication. However, due to the intrinsic band gap properties of silicon, most infrared photons are energetically useless. Here, we ...
Development of a chemiluminescence-based quantitatve lateral flow immunoassay for on-field detection of 2,4,6-trinitrotoluene

Mirasoli, Mara; Buragina, Angela; Dolci, Luisa Stella; Guardigli, Massimo; Simoni, Patrizia; Montoya Baides, Ángel; Maiolini, Elisabetta; Girotti, Stefano; Roda, Aldo (ELSEVIER SCIENCE BV, 2012)

[EN] Simple, rapid and highly sensitive assays, possibly allowing on-site analysis, are required in the security and forensic fields or to obtain early signs of environmental pollution. Several bioanalytical methods and ...
In situ size sorting in CVD synthesis of Si microspheres

Garín Escrivá, Moisés; Fenollosa Esteve, Roberto; Kowalski, L. (Nature Publishing Group, 2016-11-08)

[EN] Silicon microspheres produced in gas-phase by hot-wall CVD offer unique quality in terms of sphericity, surface smoothness, and size. However, the spheres produced are polydisperse in size, which typically range from ...
Low order modes in microcavities based on silicon colloids

Xifre Perez, Elisabet; Fenollosa Esteve, Roberto; Meseguer Rico, Francisco Javier (Optical Society of America, 2011-02-14)

[EN] Silicon colloids based microcavities, with sphere size between 1 and 3 micrometers, have been synthesized and optically characterized. Due to both the small cavity volume and the high refractive index of silicon we ...
Mirror-image-induced magnetic modes

Xifre Perez, Elisabet; Shi, Lei; Tuzer, Turan Umut; Fenollosa Esteve, Roberto; Ramiro Manzano, Fernando; Quidant, Romain; Meseguer Rico, Francisco Javier (American Chemical Society, 2013-01)

Reflection in a mirror changes the handedness of the real world, and right-handed objects turn left-handed and vice versa (M. Gardner, The Ambidextrous Universe, Penguin Books, 1964). Also, we learn from electromagnetism ...
Modelling approach to an ultrafiltration process for the removal of dissolved and colloidal substances from treated wastewater for reuse in recycled paper manufacturing

Santos-Sousa, Mayko Rannany; Lora-García, Jaime; López Pérez, Maria Fernanda (Elsevier, 2018)

[EN] In this work, ultrafiltration (UF) is used to remove dissolved and colloidal substances (DCS) from a secondary clarifier effluent from a wastewater treatment plant (WWTP) in a papermaking factory. The approach has ...
Photonic microcavities and photonic sponges based on silicon colloids

TYMCZENKO, MIKAEL KONRAD (Universitat Politècnica de València, 2010-07-09)

El silicio es un material de suma importancia en microelectronica y en fotonica. Las propiedades semiconductoras del silicio estan detras de los conceptos que gobiernan el funcionamiento de la mayoría de los dispositiv ...
Silicon nanoparticles as Raman scattering enhancers

Rodríguez, Marie-Isabelle; Shi, Lei; Lu, Xiaotang; Korgel, Brian; Alvarez -Puebla, Ramon; Meseguer Rico, Francisco Javier (Royal Society of Chemistry, 2014-06-07)

[EN] In this communication we demonstrate the large amplification values of the Raman signal of organic molecules attached to silicon nanoparticles (SiNPs). Light induced Mie resonances of high refractive index particles ...
Síntesis y aplicaciones de perovskitas libre de plomo.

Lin Lin, Jiaming (Universitat Politècnica de València, 2022-10-20)

[ES] El correspondiente trabajo de final de máster va a consistir en la síntesis de nanopartículas semiconductoras basadas en perovskitas, que sean libres de plomo o con metales menos tóxicos. Dado que las estructuras de ...
Spherical silicon photonic microcavities: From amorphous to polycrystalline

Fenollosa Esteve, Roberto; Garín Escrivá, Moisés; Meseguer Rico, Francisco Javier (American Physical Society, 2016-06-16)

[EN] Shaping silicon as a spherical object is not an obvious task, especially when the object size is in the micrometer range. This has the important consequence of transforming bare silicon material in a microcavity, so ...
