Síntese de copolímeros em bloco de p-acetoxiestireno com isopreno através de polimerização "viva" via radical livre Synthesis of block copolymers from p-acetoxystyrene and isoprene by "living" free radical polymerization [PDF]

Polímeros, 2004
Neste trabalho, é mostrada a síntese de homopolímeros de p-acetoxiestireno e copolímeros diblocos de p-acetoxiestireno com isopreno, utilizando um iniciador TEMPO-modificado, por um processo de polimerização "viva" via radical livre.

Determinação das constantes K e alfa da equação de Mark-Houwink de poli(p-acetóxiestireno) Determination of K and alpha constants of the Mark-Houwink equation of poly(p-acetoxystyrene)

Polímeros, 2004
O conceito de volume hidrodinâmico pode ser utilizado efetivamente com cromatografia de permeação em gel (GPC) e dados de viscosidade para calcular a massa molar de uma variedade de polímeros. Neste trabalho, as constantes da equação de Mark-Houwink para

Subgroups of pro-p PD3-groups [PDF]

, 2021
We study 3-dimensional Poincaré duality pro-p groups in the spirit of the work by Robert Bieri and Jonathan Hillmann, and show that if such a pro-p group G has a nontrivial finitely presented subnormal subgroup of infinite index, then either the ...

Internal gettering efficiency in p/p+ and p/p- silicon epistructures

, 2004
The efficiency of internal gettering vs. external and p(+) gettering has been investigated by EBIC contrast measurements in p/p(+) and p/p(-) epi Si on Cz substrates containing oxygen precipitates. The samples were not intentionally contaminated.

Large thermoelectric effects in p-SiC/p-Si and n-SiC/p-Si heterojunctions [PDF]

The thermoelectric effect is important for thermal sensing, energy harvesting and other applications. This paper investigates the Seebeck coefficient of silicon carbide (SiC) on silicon (Si) heterojunctions and discusses the mechanism underlying the ...
