Selective Photocatalytic Production of Aldehydes

Titania Photocatalysts for Selective Oxidations in Water
2011
Heterogeneous photocatalysis by polycrystalline semiconductor oxides is an unconventional technology that has been mainly applied for the degradation of organic and inorganic pollutants in both the vapor and liquid phase. The application of photocatalysis in synthetic routes has also been researched in recent years, demonstrating its viability as an alternative route in organic chemistry. This work illustrates the main findings in the application of heterogeneous photocatalysis to the oxidation of organic compounds dissolved in water, free of any organic co-solvent. Two main aspects of the oxidative process have been studied: the first one is the partial oxidation of various mono-substitute…
El tondo cerámico con el martirio de San Lorenzo: problemas historiográficos en torno a una pintura inédita de Josep Sanchís
1992
SOBRE EL DINTEL DE LA PUERTA PRINCIPAL DEL LLAMADO "L'HORT DE CARRERES" DE CARCAIXENT (VALENCIA) SE ENCUENTRA UN TONDO DE PINTURA CERAMICA EN EL QUE SE REPRESENTA EL MARTIRIO DE SAN LORENZO. SU FORMATO CIRCULAR ES EXCEPCIONAL DENTRO DE LA PRODUCCION CERAMICA DEL PERIODO ACADEMICO CLASICISTA. ESTA FIRMADO POR JOSEP SANCHIS (DOCUMENTADO ENTRE 1804 Y 1829), PINTOR CERAMICO VINCULADO A LAS REALES FABRICAS DE AZULEJOS DE VALENCIA. ENCARGADO PROBABLEMENTE POR LORENZO CARRERES GILABERT, EL TONDO PARECE INSPIRADO EN EL FRESCO DEL MARTIRIO DE SAN VICENTE PINTADO POR BARTOLOME MATARANA ENTRE 1597 Y 1605 EN EL CRUCERO DE LA IGLESIA DEL COLEGIO DEL PATRIARCA DE VALENCIA, LO QUE SUPONE EL ACERCAMIENTO A…
The Efficacy of Powered Oscillating Heads vs. Powered Sonic Action Heads Toothbrushes to Maintain Periodontal and Peri-Implant Health: A Narrative Re…
2021
Objectives: To compare the efficacy of rotating-oscillating heads (ORHs) VS sonic action heads (SAHs) powered toothbrushes on plaque accumulation and gingival inflammation. Methods: An electronic (MEDLINE, Embase, Inspec, PQ SciTech and BIOSIS) and a complementary manual search were made to detect eligible studies. RCTs meeting the following criteria were included: final timepoint longer than 15 days; year of publication after 2000; patients without orthodontic appliances or severe systemic/psychiatric diseases. Studies comparing two or more different types of sonic/roto-oscillating toothbrushes were excluded. Selection of articles, extraction of data, and assessment of quality were made in…

Photoelastic stress analysis assisted evaluation of fracture toughness in hydrothermally aged epoxies
2014
The present work has investigated the fracture toughness of a model DGEBA epoxy system subject to Hidro-Thermal aging. A Photoelastic Stress Analysis technique has been implemented, showing the evolution of stresses arising throughout the water uptake process due to the non-uniform swelling of the material. Gravimetric and Dynamic Mechanical Thermal Analyses have further complemented the characterization, showing the onset of plasticization effects with aging. The correlation of all previous characterizations has allowed to conclude that an increase of KIC fracture toughness is obtained at the fully saturated condition. In particular Photoelasticity has also revealed the onset of relevant s…
Interlaminar fracture toughness behavior of electron-beam cured carbon-fiber reinforced epoxy-resin composites
2013
The work describes the preparation and physical-mechanical characterization of unidirectional CFRP panels manufactured by an electron beam curing technique. Delamination fracture toughness in Mode I and II is investigated in order to evaluate the influence of fiber–matrix adhesion strength, matrix toughness and matrix crosslinking density as determined by the radiation curing process. A matrix system comprising a DGEBA epoxy monomer and an initiator of cationic polymerization have been used, with one batch of resin mixed with a PES monomer in order to enhance matrix toughness. Curing was achieved with a pulsed 10 MeV Electron Beam accelerator. Thermally cured composite systems have also bee…
Migrazioni forzate e diritti disattesi. Lo sguardo di genere sui bisogni di frontiera
2021
La definizione di “tratta di esseri umani”, adottata dal Protocollo delle Nazioni Unite, descrive gli elementi che identificano un fenomeno rilevato su scala mondiale che occupa i primissimi posti delle classifiche relative ai crimini internazionali per la diffusione e la numerosità di casi. Esso prevede l’induzione forzata a varie forme di sfruttamento e, fra queste, un posto di rilievo occupa quello relativo allo sfruttamento a scopo prostitutivo. Malgrado accordi europei e leggi nazionali convergano sul piano giuridico, allo stato attuale, la condizione di “vittima di tratta” fatica ad essere riconosciuta come tale da un sistema di protezione e accoglienza che in Europa evidenzia procedu…
Intraguild interactions between two egg parasitoids exploring host patches
2010
Intraguild interactions between two egg parasitoids, Trissolcus basalis (Hymenoptera: Scelionidae) and Ooencyrtus telenomicida (Hymenoptera: Encyrtidae), exploring egg masses of the Southern Green Stink Bug (SGSB) Nezara viridula (Heteroptera: Pentatomidae), were investigated in laboratory conditions by single, simultaneous and sequential host attack experiments. Mortality of N. viridula eggs was higher in simultaneous and sequential releases compared to single species releases. In simultaneous host exploitations, T. basalis females displayed an aggressive behavior against O. telenomicida females. The outcome of multiparasitism showed that interspecific larval competition was dominated by O…
