Chemical and functional characterization of antimicrobial metabolites isolated from ascidian Rhopalaea Birkelandi
(Universidad Nacional (Costa Rica), 2011-12)
Marine ecosystems have a very large diversity of resources, most of them still partially unknown, and a
few others exploited for development of new industrial and toxicological products. The objective of this
investigation ...
Biodegradable polyurethanes from sugar cane biowastes
(Cellulose chemistry and technology, 2011)
In a previous work, it was demonstrated that 70% of the molasses isolated from the biowaste generated by
the agro-industrialization of sugar cane allow obtaining composite materials with adequate mechanical
properties ...
Chemical constituents from Zanthoxylum setulosum (Rutaceae)
(Universidad Nacional, Costa Rica, 2011-02-10)
Following our phytochemical studies of Costa Rican plants, in this work we report the isolation and identification of eight compounds from aerial parts of Zanthoxylum setulosum (Rutaceae). They were identified as the ...
First Measurements of Biogenic Hydrocarbons in Air in a Tropical Cloudy Forest, Monteverde, Costa Rica
(David Publishing Compan, 2011)
Measurements of biogenic hydrocarbons in ambient air were carried out during 2008 in a cloud y tropical forest in Monteverde, Costa Rica. Isoprene, α-pinene, β-pinene, 3-carene, d-limonene and γ-terpinene were sampled by ...
Analysis of energy transfer and ternary non-covalent filler/matrix/UV stabilizer interactions in carbon nanofiber and oxidized carbon nanofiber filled poly(methyl methacrylate) composites
(Elsevier, 2011-10-27)
Ternary non-covalent interactions between carbon nanofibers (CNFs), oxidized carbon nanofibers (ox-
CNFs), poly(methyl methacrylate) (PMMA) chains, and benzotriazole-containing UV stabilizers were
analyzed using ...
