This paper reviews the interaction between coherently stimulated acoustic phonons in the
form of surface acoustic waves with light beams in semiconductor based photonic structures. …

Transmission of Zika virus (ZIKV) in the Americas was first confirmed in May 2015 in northeast
Brazil 1 . Brazil has had the highest number of reported ZIKV cases worldwide (more than …

The coefficient of thermal expansion (CTE), biaxial modulus, and stress of some amorphous
semiconductors (a- Si:H , a- C:H , a- Ge:H , and a- GeC x :H ) and metallic (Ag and Al) thin …

… from Angola in the end of May 2014 in Feira de Santana (FSA), the second largest city in Bahia
… A map of Feira de Santana is shown with the number of cases per district of residence for …

Nanocrystalline CeO 2 powders were synthesized by two cost-effective methods: the self-propagating
room temperature (SPRT) method and the precipitation method. Differently …

… (discarding their extremities) in slices with thickness of 5 mm and diameter of about 85–90
mm. Afterwards, each slice was cut into eight identical triangles with base of about 30–35 mm. …

Focused surface-acoustic waves (SAWs) provide a way to reach intense acoustic fields for
electro- and optoacoustic applications on semiconductors. We have investigated the focusing …

The authors demonstrate a compact optical waveguide modulator based on a Mach-Zehnder
interferometer driven by surface acoustic waves. The modulator was monolithically …

… Eighteen months after notification of the first case in the city of Feira de Santana, we conducted
the first serosurvey to define the magnitude of transmission in a rural community in Brazil. …

We show that the coherent interaction between microcavity polaritons and externally stimulated
acoustic phonons forms a tunable polariton superlattice with a folded energy dispersion …
