8. Supramolecular Architecture and Electrical Properties of a Perylene Derivative in Physical Vapor Deposited Films
The supramolecular structure of organic thin films is a key factor in their optical and electrical properties and, consequently, in the technological applications involving organic electronic. Here, thin films of a perylene derivative, the bis butylimido perylene (BuPTCD), were produced by vacuum thermal evaporation (PVD, physical vapor deposition). The main

9. Recubrimiento controlado de sustratosde vidrio con nanobastones metálicos
ABSTRACTMonodispersed gold nanorods were synthesized with efficiency above 80% of all nanoparticles, characterized by longitudinal plasmon resonance around 800 nm. Glass substrates were surface modified and covered with the synthesized nanorods with control of surface density. Coverage dynamics was monitored through extinction spectra, and a saturation maxim

11. Molecular identification and antifungal susceptibility profiles of Candida parapsilosis complex species isolated from culture collection of clinical samples
AbstractINTRODUCTION:Candida parapsilosis is a common yeast species found in cases of onychomycosis and candidemia associated with infected intravascular devices. In this study, we differentiated Candida parapsilosis sensu stricto, Candida orthopsilosis , and Candida metapsilosis from a culture collection containing blood and subungual scraping samples. Furt

12. Low-level red laser therapy alters effects of ultraviolet C radiation on Escherichia coli cells
Low-level lasers are used at low power densities and doses according to clinical protocols supplied with laser devices or based on professional practice. Although use of these lasers is increasing in many countries, the molecular mechanisms involved in effects of low-level lasers, mainly on DNA, are controversial. In this study, we evaluated the effects of l
