Journal ArticleDOI
Natural Rubber Latex Used as Drug Delivery System in Guided Bone Regeneration (GBR)
Rondinelli Donizetti Herculano,Cecília Silva,Cibele Ereno,Sérgio Augusto Catanzaro Guimaraes,Angela Kinoshita,Carlos Frederico de Oliveira Graeff +5 more
TL;DR: The morphology of the membrane is the predominant factor for higher protein release, compared with pore size and number of pores, in natural rubber latex membranes used as a protein delivery system.
Journal ArticleDOI
Nitrogen-related dopant and defect states in CVD diamond.
E. Rohrer,Carlos Frederico de Oliveira Graeff,R. Janssen,Christoph E. Nebel,Martin Stutzmann,H. Güttler,R. Zachai +6 more
TL;DR: Subbandgap absorption of chemical-vapor-deposition diamond films, with nitrogen contents varying from 10 to 132 ppm has been explored by the constant-photoconductivity method (CPM), photothermal-deflection spectroscopy (PDS), and electron spin resonance (ESR).
Journal ArticleDOI
Latex use as an occlusive membrane for guided bone regeneration
Cibele Ereno,Sérgio Augusto Catanzaro Guimarães,Silvana Pasetto,Rondinelli Donizetti Herculano,Cecília Silva,Carlos Frederico de Oliveira Graeff,Orivaldo Tavano,Oswaldo Baffa,Angela Kinoshita +8 more
TL;DR: Results show significant differences between groups suggesting that latex membranes accelerates healing in critical bone defects, demonstrating that latex can be used at injured sites as an aid in the healing process.
Journal ArticleDOI
On the release of metronidazole from natural rubber latex membranes
Rondinelli Donizetti Herculano,Alvaro Antonio Alencar de Queiroz,Angela Kinoshita,Osvaldo N. Oliveira,Carlos Frederico de Oliveira Graeff +4 more
TL;DR: It is demonstrated that the induced angiogenesis known to be provided by NRL membranes can be combined with a controlled release of drugs, whose kinetics can be tailored by modifying experimental conditions of membrane fabrication for specific applications.
Journal ArticleDOI
Hydrogen-induced transport properties of holes in diamond surface layers
Christoph E. Nebel,C. Sauerer,F. Ertl,Martin Stutzmann,Carlos Frederico de Oliveira Graeff,Philippe Bergonzo,Oliver A. Williams,Richard B. Jackman +7 more
TL;DR: In this paper, three hydrogen-terminated diamonds with different surface roughness and morphologies have been investigated by conductivity and Hall experiments in the temperature regime 0.34-350 K.
