Analysis of non-covalent interactions between the nanoparticulate fillers and the matrix polymer as applied to shape memory performance
(The Royal Society of Chemistry, 2010)
Non-covalent interactions between filler particles and polyurethanes were investigated using fluorescence emission spectroscopy. The results were used in the analysis of shape memory (SM) performance of polyurethanes. ...
Antimicrobial activities of Marcgraviaceae species and isolation of a naphthoquinone from Marcgravia nervosa (Marcgraviaceae)
(NRC Research Press, 2015)
The Marcgraviaceae is a neotropical plant family of lianas and shrubs distributed throughout Central and South America, mainly in evergreen and semi-evergreen tropical forests. In this study, extracts of 12 Marcgraviaceae ...
Baseflow recession analysis in the inland Pacific Northwest of the United States
(Springer Nature, 2015)
The storage-discharge relationships of 26 water sheds in the inland Pacific Northwest of the United States
were analyzed. Four fitting methods were used to obtain
the baseflow coefficients: lower envelope, organic corre ...
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 ...
Physicochemical and chromatographic method of characterization of Matricaria recutita tinctures
(2016)
The pharmacological activity of medicinal products containing plant materials depends on their specific components. However, these components are not characterized in their entirety in all cases. Therefore, manufacturing ...
Chemical And Extractives Compatibility Of Empty Bunch Fruit Of Elaeis Guineensis, Leaves Of Ananas Cumosos And Tetrapak With Wood Used In Particleboards In Tropical Areas
(Universidad Nacional del Sur (UNS), 2015)
Tropical countries produce a great variety of lignocellulosic residues from small-area planted crops. Large amount of "Tetra Pak" package are also produced without any disposal treatment. In order to give solutions for ...
Ecosystemic Assessment of Surface Water Quality in the Virilla River: Towards Sanitation Processes in Costa Rica
(Universidad Nacional (Costa Rica), 2018)
Water quality information is essential supporting decision making in water management
processes. The lack of information restricts, at some point, the implementation of adequate sanitation,
which is still scarce in ...
Methane Dynamics in a Tropical Serpentinizing Environment: The Santa Elena Ophiolite, Costa Rica
(Universidad Nacional (Costa Rica), 2017)
Uplifted ultramafic rocks represent an important vector for the transfer of carbon and
reducing power from the deep subsurface into the biosphere and potentially support
microbial life through serpentinization. This ...
Isotope hydrology of a tropical coffee agroforestry watershed: Seasonal and event-based analyses
(Wiley & Sons, 2018)
Stable isotope variations are extremely useful for flow partitioning within the
hydrologic cycle but remain poorly understood throughout the tropics, particularly in
watersheds with rapidly infiltrating soils, such as ...
Isolation and Characterization of Nanocellulose Obtained from Industrial Crop Waste Resources by Using Mild Acid Hydrolysis
(Tech Science Press, 2018)
Cellulose, microcrystalline cellulose and nanocellulose were prepared from three agricultural waste resources:
pineapple leaf (PALF), banana rachis (BR), and sugarcane bagasse (SCB). Each waste resource was first converted ...
