1. Projeto e fabricação de nao-estruturas por litografa interferometrica / Design and fabrication of nano-structures by interforometric lithography
In this work the interferometric lithography technique was developed for recording periodic relief nano-structures, one and bi-dimensional, on silicon and glass substrates. In particular, the work is focused in two directions: the study of the profile of the structures recorded in photorresist, through the superimposition of interference light patterns, and

2. Medidas de dispersão anômala de raios-x. / X-rays anomalous dispersion measurement.
Com a crescente disponibilidade de luz síncrotron tem-se utilizado cada vez mais a dispersão anômala (f´) no estudo de materiais. Apesar dos vários métodos já empregados na medida do fator de espalhamento atômico, ainda é pequeno o número de elementos abrangidos. Este trabalho apresenta uma contribuição à ampliação da gama de elementos mensur�

3. Vectorially oriented membrane protein monolayers: profile structures via x-ray interferometry/holography.
X-ray interferometry/holography was applied to meridional x-ray diffraction data to determine uniquely the profile structures of a single monolayer of an integral membrane protein and a peripheral membrane protein, each tethered to the surface of a solid inorganic substrate. Bifunctional, organic self-assembled monolayers (SAMs) were utilized to tether the p

4. Interference fine structure and sarcomere length dependence of the axial x-ray pattern from active single muscle fibers
Axial x-ray diffraction patterns from single intact fibers of frog skeletal muscle were recorded by using a highly collimated x-ray beam at the European Synchrotron Radiation Facility. During isometric contraction at sarcomere lengths 2.2–3.2 μm, the M3 x-ray reflection, associated with the repeat of myosin heads along the filaments, was resolved into two

5. Morphology of high-luminosity compact radio sources.
High-dynamic range imaging and monitoring with very-long-baseline interferometry reveal a rich morphology of luminous flat-spectrum radio sources. One-sided core-jet structures abound, and superluminal motion is frequently measured. In a few cases, both distinct moving features and diffuse underlying jet emission can be detected. Superluminal motion seen in

6. Vectorially oriented monolayers of detergent-solubilized Ca(2+) -ATPase from sarcoplasmic reticulum.
A method for tethering proteins to solid surfaces has been utilized to form vectorially oriented monolayers of the detergent-solubilized integral membrane protein Ca(2+) -ATPase from the sarcoplasmic reticulum (SR). Bifunctional, organic self-assembled monolayers (SAMs) possessing "headgroup" binding specificity for the substrate and "endgroup" binding speci
