The aim of this work was preparation of functional nanoparticles doped with fluorescent pH-sensitive dyes in order to develop novel optical nanosensor systems. Rhodamine B, lyophilized Nile Blue and 2-piperidinilbenzimidazo [1,2-a] quinoline-6-carbonitrile (dye 1) were used as fluorescent dyes. Silica and polymer nano…

During the outflow of the bulk material from the hopper, the particles interact with each other, the walls of hopper, forming a so-called arches. Arching is a common phenomenon at the end of bulk materials. A large number of authors fight against arches, a lot of theories and models were designed. The use of arch dest…
The aim of this doctoral thesis is the measurement of the transport properties of nano-structures and its correlation with the physical phenomenon that give rise to those results. This thesis can be divided in two fundamental sections: a) Measurements of thermal properties and b) measurements of electrical properties.…
Este trabalho tem como objetivo desenvolver um simulador dinâmico para analise de consequencia em plantas quimicas industriais. Nele, todas as etapas de um possivel acidente foram estudadas e implementadas, baseadas em modelos empiricos e semi-empiricos da literatura para acidentes de gas, liquido e de duas fases (liq…

Savannah River National Laboratory (SRNL) and Oak Ridge National Laboratory (ORNL) are developing plans for the recovery of rare and unique isotopes contained within heavy-actinide target assemblies, specifically the Mark-18A. Mark-18A assemblies were irradiated in Savannah River Site (SRS) reactors in the 1970s under…
OBJECTIVE: To compare the efficacies of endoscopic harvesting saphenous vein as sequential graft by pedicled and scheltoned technique. METHODS: From June 2013 to December 2013, a total of 93 patients undergoing coronary artery bypass with endoscopic vein harvesting in shank were recruited. Saphenous veins were harvest…
In the last three years there have been held brilliant, centennial jubilees related to X-ray crystallography. In 1912, Max von Laue announced diffraction of X-rays on a crystal and his discovery marked the birth of a new discipline -X-ray crystallography. The Nobel Prize was awarded for Laue's discovery in 1914 and on…
Abstract : In this work, cw and pulsed a 1532 and a 1440 nm laser excitation of the 4I13/2 band of Er3+ and 3F3,3F4 band of Pr3+ was explored in low phonon-energy hosts KPb2Cl5 and KPb2Br5. Crystal growth along with upconversion and eye-safe emission (approximately 1.5-1.6 m) studies were conducted on both Er3+ and Pr…
We demonstrate that tunable superoleophobic surfaces fabricated by a simple spin and spray coating methods of titania on silicon (Si) wafers and stainless steel (SS) mesh, which possess a hierarchical re-entrant structure consisting of nano meter sized particles on top of micron sized particle, are able to induce supe…
As Droseraceaeas são uma família de plantas carnívoras, características de solos pobres em nutrientes, úmidos e depauperados, com adaptações que capturam presas, absorvem seus metabólitos e os utilizam em seu crescimento e desenvolvimento. As folhas são revestidas, na face adaxial, por estruturas que produzem uma subs…
[EN] Abstract The main purpose of this thesis is the design and characterization of an experimental articular cartilage model. The in vitro model is composed of a macro and micro- porous Polycaprolactone scaffold with a Poly(Vinyl Alcohol) filling. The scaffold/hydrogel construct has been subjected to repeating number…
Penelitian ini dilakukan untuk memeriksa pengaruh dari short-time solution treatment dan short-time aging terhadap struktur mikro dan kekerasan paduan titanium Ti-6Al-4V. Tujuan dari penelitian ini adalah untuk mendapatkan biomaterial paduan Ti-6Al-4V yang kompatibel untuk penggunaan implan biomedis. Proses perlakuan…
It is well known that some liquids can demonstrate anomalous behavior. Interestingly, this be- havior can be qualitatively reproduced with simple core-softened isotropic pair-potential systems. Although anomalous properties of liquids usually take place at low and moderate temperatures it was recently recognized that…
Penelitian ini bertujuan menganalisis degan menggunakan metode statistik SPSS dengan aplikasi regresi dan Varian Anova, dimana spesimen dibuat dari serat alang-alang ( Imperata cylindrica ) dan resin epoksi dengan perbandingan komposi 60:40%,65:35%, dan 70:30%, dan ditambah pengeras hardener 4% . Dapat disimpulkan bah…
The recently-emerged concept of "invisible gateway" with the extraordinary capability to block the waves but allow the passage of other entities has attracted great attentions due to the general interests in illusion devices. However, the possibility to realize such a fascinating phenomenon for acoustic waves has not…
The contact angles of cylindrical droplets on smooth and chemically homogeneous nondeformable substrates were studied by methods of thermodynamics. The total grand potential of the system was calculated. Then, a generalized Young's equation for wetting of cylindrical droplets on chemically homogeneous and smooth subst…
Two–photon absorption was one of the first nonlinear optical phenomena to be experimentally observed, shortly after the advent of intense pulsed laser sources. It is based on the excitation of an atom or molecule from a lower electronic state to an excited state with the simultaneous absorption of two light quanta. Tw…
We report resonant features of novel controllable reflectarray which consists of meander-like graphene strips placed on a metal-backed dielectric substrate. The structure manifests two kinds of resonances appeared as sharp deeps of reflectivity. The first one exists because the strips of periodic cells of the structur…
