Hallazgo de un denario merovingio inédito de Marsella en la ciudad de Tarragona (España)
2019
Documentamos el importante descubrimiento de un denario merovingio procedente de Masilia (Marsella) en la ciudad catalana de Tarragona (España). Debido a la escasez de esta tipología, no solamente en el suelo peninsular, creemos que su publicación es de una gran importancia. Y más aún considerando que el estudio de las relaciones comerciales tanto de corto como de largo recorrido entre el reino visigodo de Toledo y la Francia merovingia se mantiene poco desarrollado. We study the important fi nding of a Merovingian denarius from Masilia (Marseille) in the Catalan city of Tarragona (Spain). Due to the scarcity of this coinage, not only in the Iberian Peninsula, we believe that its publicatio…
An inconvenient influence of iridium(III) isomer on OLED efficiency.
2010
The recently reported heteroleptic cyclometallated iridium(III) complex [Ir(2-phenylpyridine)(2)(2-carboxy-4-dimethylaminopyridine)] N984 and its isomer N984b have been studied more in detail. While photo- and electrochemical properties are very similar, DFT/TDDFT calculations show that the two isomers have different HOMO orbital characteristics. As a consequence, solution processed OLEDs made using a mixture of N984 and isomer N984b similar to vacuum processed devices show that the isomer has a dramatic detrimental effect on the performances of the device. In addition, commonly used thermogravimetric analysis is not suitable for showing the isomerization process. The isomer could impact pe…
ChemInform Abstract: Luminescent Ionic Transition Metal Complexes for Light-Emitting Electrochemical Cells
2012
Higher efficiency in the end-use of energy requires substantial progress in lighting concepts. All the technologies under development are based on solid-state electroluminescent materials and belong to the general area of solid-state lighting (SSL). The two main technologies being developed in SSL are light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs), but in recent years, light-emitting electrochemical cells (LECs) have emerged as an alternative option. The luminescent materials in LECs are either luminescent polymers together with ionic salts or ionic species, such as ionic transition-metal complexes (iTMCs). Cyclometalated complexes of IrIII are by far the most utiliz…
In vivo manipulation of Vgamma9Vdelta2 T cells with zoledronate and low-dose interleukin-2 for immunotherapy of advanced breast cancer patients.
2010
The potent anti-tumour activities of gamma delta T cells have prompted the development of protocols in which gamma delta-agonists are administered to cancer patients. Encouraging results from small Phase I trials have fuelled efforts to characterize more clearly the application of this approach to unmet clinical needs such as metastatic carcinoma. To examine this approach in breast cancer, a Phase I trial was conducted in which zoledronate, a V gamma 9V delta 2 T cell agonist, plus low-dose interleukin (IL)-2 were administered to 10 therapeutically terminal, advanced metastatic breast cancer patients. Treatment was well tolerated and promoted the effector maturation of V gamma 9V delta 2 T …
ChemInform Abstract: Hybrid Organic-Inorganic Light-Emitting Diodes
2011
The demonstration of colour tunability and high efficiency has brought organic light-emitting diodes (OLEDs) into the displays and lighting market. However, high production costs due to expensive deposition techniques and the use of reactive materials still limit their market entry, highlighting the need for novel concepts. This has driven the research towards the integration of both organic and inorganic materials into devices that benefit from their respective peculiar properties. The most representative example of this tendency is the application of metal oxides in organic optoelectronics. Metal oxides combine properties such as high transparency, good electrical conductivities, tuneable…

Papel de la ecoendoscopia previa a la CPRE ante la sospecha de coledocolitiasis
2017
RESUMEN PROYECTO TESIS DOCTORAL. Autor: Ana Belén Durá Ayet. Título Provisional del proyecto de tesis: Papel de la ecoendoscopia previa a la CPRE ante la sospecha de coledoolitiasis. Tema. La Colangiopancreatografía retrógrada endoscópica (CPRE) ha sido considerada durante muchos años la técnica de elección en el diagnóstico preoperatorio de la coledocolitiasis, sin embargo se asocia a una tasa nada despreciable de complicaciones como riesgo de pacreatitis, hemorragias y perforación que se estima entre un 2-20% según las series. El avance tecnológico ha permitido obtener mediante otras técnicas no invasivas (Colangiopancreatografía por resonancia magnética-CPRM) o mínimamente invasivas (Ult…
