My PhD reasearch activity was mainly focused on two different fields: the study of the formation of supramolecular architectures and the investigation of the photophysical behaviour of different photocatalysts in organic reactions. The first supramolecular system shown in this thesis derives from a shapepersistent mol…
Scaffolds play an important role in cartilage tissue engineering as they can support regeneration of the damaged tissue which cannot be restored by standard medical interventions. Collagen type I and its denatured form, gelatin are widely used biomaterials in scaffolds’ synthesis due to their high biodegradability and…
Although certain quenched titanium alloy sheets exhibit excellent damping properties, the effect of dimensions has not been clarified. In this study, the cooling rate, microstructure, phase constitutions, lattice parameters, and hardness distribution of cylindrical specimens of Ti-(15, 18, 20) mass%Nb alloys were inve…
Cell infiltration is one of the most important characteristics of a degradable and bioactive biomaterial. Poly (ethylene glycol) (PEG), as one of the most commonly used polymer in medicine, also faces such problems. This issue also prevalence in PEG derivatives such as poly (ethylene glycol)-glutaric acid-dopamine (PE…
The crystal growth of large, defect-free and optically transparent materials has been an active area of research for over two centuries. A multitude of crystal growth techniques have been employed during this time, each submitting advantages and disadvantages to the solid-state community. As the heart of solid state l…
Radiation exposure level in some granite quarry sites in Ohimini and Gwer-East Local Government Areas of Benue State was carried out using radiation meter (radiation alert inspector). The research investigated only the exposure dose rate, the mean absorbed dose and the mean annual effective dose equivalent of the radi…

A modified multi-element inverse-diffusion flames (m-IDFs) burner setup is utilized to synthesize mono-layer graphene and carbon nanotubes (CNTs) on metal and non-metal substrates. The growth mechanisms of mono-, bi-, and few-layer graphene (MLG, BLG, and FLG, respectively) and their defect level using unconfined flam…
Esta Tese consiste de um estudo experimental sobre a formação de texturas magnéticas em heteroestruturas do tipo filmes finos bi, tri e multicamadas. A investigação é feita através de medidas de magnetização, propriedades de magnetotransporte elétrico e imageamento por magneto-óptica. Foram produzidos e estudados dois…
Terahertz field induced photocurrents in graphene were studied experimentally and by microscopic modeling. Currents were generated by cw and pulsed laser radiation in large area as well as small-size exfoliated graphene samples. We review general symmetry considerations leading to photocurrents depending on linear and…
Исследована излучательная дезактивация нижних возбужденных триплетного и синглетного состояний для семейств свободных оснований и Zn -комплексов водорастворимых 5,10,15,20- тетракис-(4-сулъфонатофенил)-порфирина (Н2ТСФП), 5,10,15,20-тетракис-(4-К-алкилпиридил)-порфирина (Н2Т4АлкПиП), 5,10,15,20-тетракис-(3-И-алкилпири…
Treating defects in nuclear reaction models to improve material damage parameters and their uncertainties
A determinação experiemntal da seção de choque de produção de raios X induzida por feixe de íons tem sido objeto de vários trabalhos nas últimas décadas, tendo em vista que este é um dos principais fatores que afetam a quantificação composicional de uma análise PIXE baseada em parâmetro fundamentais ( standardless). C…
La tendance actuelle vers l’encapsulation d’un assemblage comportant plusieurs puces favorise l’incorporation d’un procédé de réusinage compatible avec l’enlèvement et le remplacement d’une puce défectueuse. La vérification électrique est un procédé inhérent au réusinage qui identifie facilement les puces défectueuses…
The series of heteropoly complexes were prepared by conventional reflux method in the water bath separately by taking Isopoly anions of Mo, V, W. All the products isolated were crystalline in nature appeared as dark yellow products. The chemical as well as physical methods were applied to characterize all the three is…
El progreso de los avances científicos en los últimos años centró sus esfuerzos en el estudio de factores que hacen a la esencia del implante. Entre los nuevos materiales se encuentra el zirconio, como elemento de excelente biocompatibilidad que, al permitir buen soporte de labios, brindar estética bucal, no interfier…

OBJECTIVE: The purpose of this in vitro study was to evaluate the cutting performance and accuracy of CAD/CAM diamond burs in different chemo-mechanical conditions when machining yttria-stabilized zirconia (YTZ), lithium-disilicate, feldspathic porcelain, and double network hybrid ceramic material. The study also exam…
Magnesium (Mg) alloys are promising structural metallic materials owing to their low density and high specific strength. Mg alloys have been used in many industries including aerospace and vehicle parts, and portable electronic devices, where weight saving is of crucial importance. Researchers around the world are eng…
