A new CdTe/ZnO columnar composite film for Eta-solar cells

2002

Abstract First results of CdTe deposition on ZnO films consisting of free standing single crystalline columns of several micrometers height and ∼100– 200 nm diameter are presented. The ZnO films have been obtained by electrochemical deposition on conductive glass. Morphology, structural and optical properties of the nanostructured columnar CdTe/ZnO composite films have been studied. The cadmium telluride ( 40 nm thick) deposited by vapor-phase epitaxy under dynamical vacuum is lining the ZnO columns as a continuous smooth thin film with conformal coverage. The polycrystalline CdTe layer is a mixture of cubic and hexagonal phases and is semiconductor with a direct band gap optical transition…

Application of 2D Non-Graphene Materials and 2D Oxide Nanostructures for Biosensing Technology

2016

The discovery of graphene and its unique properties has inspired researchers to try to invent other two-dimensional (2D) materials. After considerable research effort, a distinct "beyond graphene" domain has been established, comprising the library of non-graphene 2D materials. It is significant that some 2D non-graphene materials possess solid advantages over their predecessor, such as having a direct band gap, and therefore are highly promising for a number of applications. These applications are not limited to nano- and opto-electronics, but have a strong potential in biosensing technologies, as one example. However, since most of the 2D non-graphene materials have been newly discovered,…

Conceptualización y medición del valor percibido: consensos y controversias

2019

[ES] Estudiar el concepto Valor resulta ser necesario y útil en Marketing por ser un concepto endémico para la disciplina y relevante para la profesión. Sin embargo, a pesar de décadas de investigación, la doctrina se lamenta de un cierto círculo vicioso sobre las dificultades conceptuales y de medición del Valor. Este trabajo revisa estas dificultades y las categoriza en torno a acuerdos y controversias, evidenciando sus efectos en la compleja red nomológica construida a lo largo de los años en torno al Valor. Además, explora empíricamente tres modelos causales de relaciones entre dimensiones de Valor, Satisfacción y Lealtad, testados con PLS sobre una muestra de 340 clientes de hotel. Los…

A Novel Digital Technique for Measuring the Accuracy of an Indirect Bonding Technique Using Fixed Buccal Multibracket Appliances

2021

The aim of this study was to analyze the accuracy and predictability of the indirect bonding technique of fixed buccal multibracket appliances using a customized iterative closest point algorithm. Materials and Methods: A total of 340 fixed buccal multibracket appliances were virtually planned and bonded on 34 experimental anatomically based acrylic resin models by using orthodontic templates designed and manufactured to indirectly bond the fixed buccal multibracket appliances. Afterwards, the models were submitted to a three-dimensional impression technique by an intraoral scanner, and the standard tessellation language digital files from the virtual planning and the digital impression wer…

Detection of canine parvovirus antigens with antibodies to synthetic peptides

1996

Antibodies produced in rabbits against an 18-amino acid peptide (peptide 1, NSLPQSEGATNFGDIGVP) of capsid protein VP2/residues 292-309 of canine parvovirus (CPV) or against an 18-amino acid peptide (peptide 2, GKRNTVLFHGPASTKGKS) of nonstructural protein NS1/residues 391-409 of CPV identified, in immunofluorescence analysis, viral antigens in canine A 72 cells infected with CPV. Antibodies to peptide 2 also identified viral antigens in bovine cells infected with bovine parvovirus. In western blot analysis, antibodies to peptide 1 and peptide 2 also detected viral antigens derived from blue fox parvovirus, feline parvovirus, mink enteritis virus and raccoon dog parvovirus. The peptide antibo…

In vivo optical coherence tomography imaging in a case of mucous membrane pemphigoid and a negative Nikolsky's sign.

2017

There is currently a growing interest in new diagnostic tools of the oral cavity and mucosa which are non-invasive, repeatable and reliable. A diagnosis of a suspected, autoimmune pathology was made regarding a 57-year-old patient with desquamative gingivitis. However, a negative Nikolsky's sign did not seem to indicate a diagnosis of mucous membrane pemphigoid neither was there any indication as to the optimum location for an incisional biopsy. As an imaging method, the use of optical coherence tomography (OCT) has enabled the obtaining of tomographic (cross-sectional) scans of tissue. Such images are acquired prior to and after verifying Nikolsky's sign, thereby enabling the clinician to …

Computer-Assisted Classification Patterns in Autoimmune Diagnostics: The AIDA Project.

2016

International audience; Antinuclear antibodies (ANAs) are significant biomarkers in the diagnosis of autoimmune diseases in humans, done by mean of Indirect ImmunoFluorescence (IIF) method, and performed by analyzing patterns and fluorescence intensity. This paper introduces the AIDA Project (autoimmunity: diagnosis assisted by computer) developed in the framework of an Italy-Tunisia cross-border cooperation and its preliminary results. A database of interpreted IIF images is being collected through the exchange of images and double reporting and a Gold Standard database, containing around 1000 double reported images, has been settled. The Gold Standard database is used for optimization of …
