Levulinic acid conversion to 2-methyltetrahydrofuran over Ni-Cu/Al2O3 catalysts
(2017-02-17)
El ácido levulínico (LA) es un compuesto derivado de la biomasa con gran proyección para los futuros procesos de biorrefinería, como la producción 2-metil tetrahidrofurano (MTHF) y otros biocombustibles. La producción ...
The Antifungal Activity Of Functionalized Chitin Nanocrystals In Poly (Lactid Acid) Films.
(MDPI AG, 2017-05-18)
As, in the market, poly (lactic acid) (PLA) is the most used polymer as an alternative to conventional plastics, and as functionalized chitin nanocrystals (CHNC) can provide structural and bioactive properties, their ...
Design and characterization of hybrid polymeric materials based on PE-b-PEO block copolymer.
(2017-07-21)
Este trabajo de investigación consiste en el desarrollo de diferentes materiales híbridos basados en uncopolímero de bloque de tipo PE-b-PEO. La principal motivación del empleo de copolímeros de bloquees su capacidad para ...
Soil Erosion and Forests Biomass as Energy Resource in the Basin of the Oka River in Biscay, Northern Spain
(MDPI, 2017-07)
The aim of this work has been the development of a methodology for the evaluation of residual forest biomass in Biscay, a province in northern Spain. The study area is located in the Oka river basin, an area of great ...
Strain sensitive conductive polyurethane foam/graphene nanocomposites prepared by impregnation method
(Elsevier, 2017-03-14)
Se prepararon nanocompuestos de espuma de poliuretano conductores mediante la incorporación de flakes de grafeno. Los flakes de grafeno se obtuvieron a partir de grafito por el método de exfoliación líquida en N metilpirrolidona ...
Analysis of the effect of temperature reaction time on yields, compositions and oil quality in 3 catalytic and non-catalytic lignin solvolysis in a formic acid/water media using experimental design.
(Elsevier, 2017-03-01)
[EN] The catalytic solvolysis of Norway spruce (Picea abies L.) lignin in a formic acid/water media was explored at different temperatures and reaction times (283–397 °C and 21–700 min, respectively). Non-catalyzed experiments ...
Azopolymer film as an actuator for organizing multiwall carbon nanotubes
(Elsevier, 2017-01-25)
In this work we show the feasibility of using an azopolymer as an actuator to induce nano- and
microscale movements controlled with light from the far field. We study azopolymers and their interaction
with multi-walled ...
Chicken feathers as a natural source of sulphur to develop sustainable protein films with enhanced properties
(Elsevier, 2017-08-05)
In this work, the effect of hydrolyzed keratin on the properties of soy protein-based films was analyzed when different manufacture processes were employed. It is widely known that the processing method selected can affect ...
