Controlling light diffraction with nanostructures

Tufaile A., Tufaile A.P.B., Vanderelli T.A., Snyder M., Tufaile A., Tufaile A.P.B., University of Sao Paulo, BR
We are presenting the main results of our research using smart fluids to control the light scattering using some devices based on nanotechnology. We are presenting the Ferrolens or Ferrocell®, which consists of a Hele-Shaw [...]

Nanostructured biopolymers obtained from blends by extrusion

Rodriguez J.H., Tadini C.C., Gastaldi E., University of Sao Paulo, BR
The extrusion of biopolymers is a promising technology for the plastic industry since enables to lead to wide range of innovative and environmentally friendly products displaying many advantages for the food packaging sector such the [...]

Drug delivery system based on inorganic layered materials

Cunha V.R.R., Petersen P.A.D., Petrilli H.M., Constantino V.R.L., University of Sao Paulo, BR
Layered Double Hydroxides (LDHs) are well known inorganic carriers which have been explored during the development of new materials for medicinal and pharmacological applications. The solubility and chemical stability of guest species can be increased [...]

Polymer-based delivery vehicle for cisplatin

Vieira D.B., Menck C.F.M., Carmona-Ribeiro A.M., University of Sao Paulo, BR
Cisplatin (CisPt) is one of the most widely used agents to treat a variety of tumors, but dose-limiting toxicities or intrinsic and acquired resistance limit its application. We report a unique strategy to deliver cisplatin [...]

Molecular orientation in electrospun poly(butylene terephthalate) nanofibers

Catalani L.H., Collins G., Jaffe M., University of Sao Paulo, BR
In this work, poly(butylene terephthalate) (PBT) electrospun fibers were produced by conventional electrospinning technique. All typical parameters dependences were studied. Typical behavior was observed for all parameters. In addition, we have analyzed molecular features of [...]

Surface Roughness as a Function of the DLC Thickness Coating

Salvadori M.C., Martins D.R., Cattani M., University of Sao Paulo, BR
In this work we have analyzed the evolution of surfaces roughness coated with DLC. This study explores substrates with initial roughness (rms) between hundreds of nanometers and just few nanometers. We have used three substrates, [...]

Nanostructured Metallic Thin Films: Measurement of Critical Exponents

Melo L.L., Farias R.J.C., Salvadori M.C., Cattani M., University of Sao Paulo, BR
We have deposited metallic films (Au, Pt) on silicon substrates. The deposition technique was the Metal Plasma Immersion Ion Implantation and Deposition. Their roughnesses have been measured using a Scanning Tunneling Microscope. From these roughnesses, [...]

Diamond Replicas on Silicon Substrate

Martins D.R., Mansano R., Verdonck P., Salvadori M.C., University of Sao Paulo, BR
Most microelectromechanical system (MEMS) devices have been based on silicon. This is due to the technological know-how accumulated on the manipulation, machining and manufacturing of silicon. However, the silicon properties are poor, especially when compared [...]
