IDENTIFICAÇÃO POR CG-EM E ANÁLISE COMPORTAMENTAL, VIA ACP, DE HPA E SUAS FONTES NO RIACHO ALGODOAIS -SUAPE/PE [PDF]

Anais do XX Congresso Brasileiro de Engenharia Química, 2015
RESUMO – Os Contaminantes Emergentes (CE) tem contribuido no aumento da poluicao ambiental, sobretudo em recursos hidricos, sendo estes caracterizados por se apresentarem em baixas concentracoes, μg.L– pg.L, porem alta persistencia e toxicidade. Dentre os CE, os Hidrocarbonetos Policiclicos Aromaticos (HPA) sao compostos orgânicos com dois ou mais ...

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

Advanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

RNA‐Micelles as Self‐Assembling Structures for Efficient Co‐Delivery of Synergistic siRNA and Nucleoside Analogues to Treat CRC Lung Metastasis

Advanced Functional Materials, EarlyView.
Two kinds of self‐assembled RNA micelles were used to co‐deliver synergistic siRNA and nucleoside analogues for the treatment of colorectal cancer lung metastases. Near‐complete elimination of lung cancer metastases was confirmed in an orthotopic lung metastasis model constructed using human colorectal cancer lung metastases patient surgical samples to
