Abstract The quantum breakdown of superconductivity (QBS) is the reverse, comprehensive approach to appearance superconductivity. A phase transition from superconducting insulating states tuned by using nonthermal parameters fundamental importance understanding (SC) but also practical applications SC materials. However, mechanism a nonzero resistive state deep in still under debate. Here, we re...
Samples of uranium diboride were sintered in inert, reducing and vacuum conditions with without the addition powdered carbon to green pellets. Carbon has been shown improve sintering materials via formation gaseous phases at lower temperatures than those which grain coarsening occurs. The 0.5 wt.% was seen sample density both conditions, while an increase content 1 decreased achieved atmosphere...
The aim of this study was to examine the influence of collagen coating on titanium on the initial attachment of human gingival fibroblasts for the development of the implant with periimplant soft tissue attachment. The morphological changes of cultured human gingival fibroblasts were investigated by scanning electron microcopy (SEM). Four different surfaces, i.e. non-coated mirror-polished tita...
PURPOSE The aim of this study was to evaluate whether photofunctionalization of titanium mesh enhances its osteoconductive capability. MATERIALS AND METHODS The titanium mesh (0.2 mm thickness) used in this study was made of commercially pure grade-2 titanium and had hexagonal apertures (2 mm width). Photofunctionalization was performed by treating titanium mesh with UV light for 12 minutes u...
This photocatalytic conversion of carbon dioxide laboratory experiment is designed for an advanced undergraduate chemistry or chemical engineering majors laboratory course. It introduces the science of emerging sustainable energy technologies through hands-on experimentation. By photo-irradiating a glass flask containing water, catalyst, and carbon dioxide, students explore the potential of new...
Flocculation with titanium tetrachloride (TiCl(4)) and titanium sulfate (Ti(SO(4))(2)) was investigated in terms of different coagulant doses, pH, turbidity, dissolved organic carbon (DOC), UV-254, colour, zeta potential, particle size and molecular weight distribution. The two coagulants were compared with the commonly used coagulants such as ferric chloride (FeCl(3)) and aluminium sulfate (Al...
The discovery of superconductivity at 39 K in magnesium diboride offers the possibility of a new class of low-cost, high-performance superconducting materials for magnets and electronic applications. This compound has twice the transition temperature of Nb3Sn and four times that of Nb-Ti alloy, and the vital prerequisite of strongly linked current ̄ow has already been demonstrated. One possible ...
