Biomass Pyrolysis Solids as Reducing Agents: Comparison with Commercial Reducing Agents
(MDPI, 2016-01)
Biomass is one of the most suitable options to be used as renewable energy source due to its extensive availability and its contribution to reduce greenhouse gas emissions. Pyrolysis of lignocellulosic biomass under ...
Characterization of Wood‑based Industrial Biorefinery Lignosulfonates and Supercritical Water Hydrolysis Lignin
(Springer, 2020-11)
Understanding the properties of any particular biorefinery or pulping residue lignin is crucial when choosing the right lignin for the right end use. In this paper, three different residual lignin types [supercritical water ...
Copolímeros de poliuretano del tipo poli[(hexametilen-carbamato- butanodiol)-co-(carbonato-co-éster)]
(Universidad Industrial de Santander, 2016-12)
Resumen Los poliuretanos segmentados termoplástico elastoméricos (PUSTE) comprenden una familia de materiales muy versátiles debido a su potencial empleo en diversos campos tales como biomedicina. Entre los PUSTE los ...
Optimization and Validation of Thermal Desorption Gas Chromatography-Mass Spectrometry for the Determination of Polycyclic Aromatic Hydrocarbons in Ambient Air
(Hindawi, 2018-05-02)
Thermal desorption (TD) coupled with gas chromatography/mass spectrometry (TD-GC/MS) is a simple alternative that overcomes the main drawbacks of the solvent extraction-based method: long extraction times, high sample ...
Heterogeneous Catalytic Ozonation of Aniline-Contaminated Waters: A Three-Phase Modelling Approach Using TiO2/GAC
(MDPI, 2020-12-08)
This work aims to study the sustainable catalytic ozonation of aniline promoted by granular active carbon (GAC) doped with TiO2. Aniline was selected as a model compound for the accelerator manufacturing industries used ...
Cellulose Nanocrystal Membranes as Excipients for Drug Delivery Systems
(MDPI, 2016-12-12)
In this work, cellulose nanocrystals (CNCs) were obtained from flax fibers by an acid hydrolysis assisted by sonochemistry in order to reduce reaction times. The cavitation inducted during hydrolysis resulted in CNC with ...
Functional Chitosan Derivative and Chitin as Decolorization Materials for Methylene Blue and Methyl Orange from Aqueous Solution
(MDPI, 2019-02-01)
Dyes are classified as one of the major pollutants of water. They have negative impacts not only on environment but also on human health. In fact, wastewater that contains these harmful substances requires many types of ...
Value-Added Bio-Chemicals Commodities from Catalytic Conversion of Biomass Derived Furan-Compounds
(MDPI, 2020-08-07)
The depletion of fossil resources in the near future and the need to decrease greenhouse gas emissions lead to the investigation of using alternative renewable resources as raw materials. One of the most promising options ...
Physicochemical and Biological Performance of Aloe Vera-Incorporated Native Collagen Films
(MDPI, 2020-12-02)
Collagen was obtained from porcine skin by mechanical pretreatments with the aim of preserving the triple helix structure of native collagen, which was indirectly corroborated by differential scanning calorimetry (DSC) and ...
