Glass transition and degree of conversion of a light-cured orthodontic composite
(2009-01-01)
Objective: This study evaluated the glass transition temperature (Tg) and degree of conversion (DC) of a light-cured (Fill Magic) versus a chemically cured (Concise) orthodontic composite. Material and Methods: Anelastic ...
Glass transition and degree of conversion of a light-cured orthodontic composite
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2009-11-01)
Objective: This study evaluated the glass transition temperature (T(g)) and degree of conversion (DC) of a light-cured (Fill Magic) versus a chemically cured (Concise) orthodontic composite. Material and Methods: Anelastic ...
Diffusion of Interstitial Elements in Ti Alloys used as Biomaterials
(Trans Tech Publications Ltd, 2009-01-01)
Titanium alloys are excellent implant materials for orthopedic applications due to their desirable properties, such as good corrosion resistance, low elasticity modulus, and excellent biocompatibility. The presence of ...

(2008-01-01)
Titanium alloys are excellent implant materials for orthopedic applications due to their desirable properties, such as good corrosion resistance, low elasticity modulus, and excellent biocompatibility. The presence of ...
Diffusion of Nitrogen in Ti-13V-11Cr-3Al Alloys
(Trans Tech Publications Ltd, 2009-01-01)
Metals with a bcc crystalline structure such as Ti-13V-11Cr-3Al alloys have their physical properties significantly changed through the addition of interstitial elements such as oxygen and nitrogen. These metals can dissolve ...
Identifying Sequential Substrate Binding at the Single-Molecule Level by Enzyme Mechanical Stabilization
(ACS Publications, 2015)
Enzyme-substrate binding is a dynamic process intimately coupled to protein structural changes, which in turn changes the unfolding energy landscape. By the use of single-molecule force spectroscopy (SMFS), we characterize ...
Antioxidant effect of resveratrol in single red blood cells measured by thermal fluctuation spectroscopy
(Facultad de Ingeniería y Tecnología, 2019)
The human red blood cell (RBC) membrane has significant elastic capabilities which can be described measuring typical membrane edge fluctuations and mechanical properties by optical techniques. The RBC elastic properties ...
Diffusion of Interstitial Solutes in Nb-46wt% Ti Alloys Measured by Mechanical Spectroscopy
(Trans Tech Publications Ltd, 2012-01-01)
The mechanical properties of metals with a body-centered cubic (bcc) structure, such as Nb, Ta, V, and their alloys, are modified with the introduction of interstitial impurities, such as O, N, C, or H. These metals can ...
On observation of the downconversion mechanism in Er3+/Yb3+ co-doped tellurite glass using thermal and optical parameters
(Elsevier B.V., 2015-01-01)
In this work we report the observed downconversion (DC) mechanism in Er3+/Yb3+-codoped tellurite glasses (in mol%, 80TeO(2)-10Li(2)O-10TiO(2)). The samples were synthesized by the conventional melt-quenching method and ...
