Abstract This study focuses on synthesizing gallium-containing hydroxyapatite (Ga-HA) with chlorhexidine (CLX) for potential use in bone and dental tissue restoration. The Ga-HA/CLX materials were prepared using a suspension-precipitation method surface-functionalized varying CLX concentrations. X-ray diffraction analysis confirmed the hexagonal structure of Ga-HA space group P63/m, while XPS revealed presence gallium Ca/P ratio ranging from 1.50 to 1.72. Infrared spectra exhibited...
A rectangular graphyne sheet is composed of units similar to phenyl rings that are linked by acetylenic chains, as in hexagonal γ-graphyne.This system organized over a lattice the recently synthesized biphenylene network.We investigate stability this from different perspectives and study its electronic structure.Rectangular semiconducting pristine form features pair highly localized states.These characteristics correlated with structural anisotropy system, since frontier states behave like...
O estudo prático sobre campo magnético e como ele se relaciona com outras grandezas físicas são conteúdos que acabam sendo muito pouco abordados em sala de aula, apesar ser uma área da Física desperta a curiosidade dos estudantes. Com o intuito minimizar esta falha, este trabalho utiliza Sequência Ensino Investigativo (SEI) para ensinar através elaboração um dispositivo eletrônico baseado no efeito Hall utilizando Arduino. utilizado nesta pesquisa foi produzido Laboratório Pesquisa Materiais...
This research aims to develop new 3D (three-dimensional) printable resins made from methacrylate salts of imidazole, 2-methyl-imidazole, and 1-methyl-imidazole, with glycerol trimethacrylate serving as a crosslinking agent. With their backbone structure, these are easy rapid prepare, offering an alternative conventional ones. Reinforced terpene-based additives such α-pinene, (R)-limonene, trans-ethyl cinnamate, safrole, they present diverse range fifteen resin formulations. Each underwent...
As propriedades eletrônicas de nanomateriais constituídos Carbono têm atraído a atenção da comunidade científica nas últimas décadas. Os detalhes estruturais desses sistemas são fundamental importância para descrever suas propriedades. Com o objetivo oferecer uma revisão fundamentos que permita ingresso em áreas pesquisa se relacionam à nanociência, este trabalho dedica investigar as físicos unidimensionais forma sistemática e pedagógica. Utilizamos um simples modelo Tight – Binding obter...
A rectangular graphyne sheet is composed of units similar to phenyl rings that are linked by acetylenic chains, as in hexagonal $\gamma$-graphyne. This system organized over a lattice the recently synthesized biphenylene network. We investigate stability this from different perspectives and study its electronic structure. Rectangular semiconducting pristine form features pair highly localized states. These characteristics correlated with structural anisotropy system, since frontier states...
