The development of small (40-150nm) nanoparticles is of significant interest in biomedicine for effective detection and delivery of therapeutic molecules to diseased cells. The optical exploration of hollow gold nanoshells with sacrificial Co cores reveals the spectral FWHM increases due to the presence of Co while on…

Ce travail de thèse a été consacré au développement d’un système multicouche constitué de nanoparticules dopées par des ions terres rares (le cœur), entourées d’une première couche cristalline non dopée, permettant de préserver les propriétés optiques du cœur. Une coquille de silice mésoporeuse est ensuite déposée, pe…
Junya Watanabe is a master of shaping and manipulating carefully chosen, often technically advanced material. This dress, designed for his Spring 2008 collection, exemplifies the designer’s keen interest in sculpting novel creations replete with historical references. Collaborating with Liberty of London, Watanabe emp…

O Brasil ocupa uma posição de destaque no cenário mundial da produção e exportação de rochas ornamentais devido a sua diversidade litológica e por abrigar todas as fases da cadeia produtiva, desde a lavra até o esquadrejamento de ladrilhos. No entanto, apesar da grande importância que este setor representa para a bala…
A Nappe Socorro-Guaxupé faz parte da porção sul da Faixa Brasília, a qual delimita a porção oeste e sul do Cráton do São Francisco. A faixa é composta por três unidades: Unidade Granulítica Basal, Unidade Diatexítica Intermedi ária e Unidade Metatexítica Superior, provenientes da raiz de arco magmático. Na região estu…
A detecção de descargas parciais em transformadores consiste em importante metodologia de manutenção preventiva e preditiva. Neste contexto, a proposta desta pesquisa com o uso de sensores acústicos de piezoeletreto apresenta-se como um tema original e altamente relevante no desenvolvimento da tecnologia brasileira. A…
Com o passar do tempo, a população mundial vem se conscientizando mais sobre problemas ambientais. Isso fez surgir uma demanda por tecnologias novas que possam se encaixar no cenário de sustentabilidade. Instabilidades frequentes no cenário político-econômico global acabam por elevar o preço do barril do petróleo. Ass…
Purpose. High chromium cast irons with austenitic matrix have low machinability. The aim of work is search of new energy-saving modes of preliminary softening heat treatment enhancing the machinability of castings by forming an optimum microstructure. Methodology. Metallographic analysis, hardness testing and machinab…
Purpose. The purpose of work is an estimation of influence of an electric spark treatment on the state of mouldable superficial coverage of carbon steel. Methodology. The steel of fragment of railway wheel rim served as material for research with chemical composition 0.65% С, 0.67% Mn, 0.3% Si, 0.027% P, 0.028% S. Str…
In this study, high frequency (40.68 MHz) RF capacitively coupled discharge was used to modify tensile strain and chemical structure of unsized PAN-based carbon fiber under different RF powers, pure nitrogen gas pressures and exposure times. The plasma parameters were diagnosed by using single and double Impedans Lang…
InAs/GaAs quantum dot solar cells have been fabricated and tested under 1-sun and up to 500-suns optical concentration. At 1-sun, the quantum dots are found to increase the short circuit current by ~4% relative to a control device without quantum dots. Furthermore, the evolution of the short circuit current with open…
Στην παρούσα διπλωματική εργασία γίνεται καταγραφή σημάτων τάσης, ρεύματος, ηλεκτρικού πεδίου και εκπεμπόμενου φωτός κατά την εφαρμογή κρουστικών τάσεων σε ένα διάκενο ανομοιογενούς πεδίου ράβδου-πλάκας. Σκοπός της εργασίας είναι η μελέτη φαινομένων που προηγούνται της διάσπασης σε ένα διάκενο ράβδου-πλάκας χρησιμοποι…
Consumer preferences for textile products are largely determined by sensory characteristics. In this context, the tactile senses are among the most important. Various sensory evaluation methods have been developed to characterize the tactile feeling from the consumer's point of view. However, sensory assessments are t…
Since textile composites are widely used for residential interiors and vehicles there is a need for a comprehensive analysis of their consumer properties and running ability. Methods of analysis will not only design new materials with desired properties but also to use them in the learning of highly qualified professi…
