Industrial wood modification by heat treatments
(2018-02-23)
El objetivo principal de este trabajo de tesis fue el de mejorar las propiedades naturales de la madera solida modificándola químicamente por medio de calor a altas temperaturas. La tecnología de termo-tratado ha despertado ...
3D Printed Chitosan-Pectin Hydrogels: From Rheological Characterization to Scaffold Development and Assessment
(MDPI, 2021-10-21)
Chitosan-pectin hydrogels were prepared, and their rheological properties were assessed in order to select the best system to develop scaffolds by 3D printing. Hydrogels showed a weak gel behavior with shear thinning flow ...
Removal of Aniline and Benzothiazole Wastewaters Using an Efficient MnO2/GAC Catalyst in a Photocatalytic Fluidised Bed Reactor
(MDPI, 2021-09-10)
This work presents an efficient method for treating industrial wastewater containing aniline and benzothiazole, which are refractory to conventional treatments. A combination of heterogeneous photocatalysis operating in a ...
Water Reuse Study from Urban WWTPs via c-Ultrafiltration and Ozonation Technologies: Basis for Resilient Cities and Agriculture
(MDPI, 2021-02-12)
The water–development nexus is essential for the advancement and progress of cities in the face of problems such as climate change, water security and increasing environmental stress in the agricultural sector. Aiming for ...
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 ...
Thermally Resistant, Self-Extinguishing Thermoplastic Composites Enabled by Tannin-Based Carbonaceous Particulate
(MDPI, 2022-09-07)
Flame-resistant materials are key components in buildings and several other engineering applications. In this study, flame retardancy and thermal stability were conferred to a highly flammable technical thermoplastic&mda ...
Bioactive molecules in wood extractives: Methods of extraction and separation, a review
(Elsevier, 2022-10)
Bioactive molecules are those capable of interacting with living organisms, causing changes in them. Wood extractives contain important amounts of these molecules, and some of them have good antioxidant and antimicrobial ...
Developing active and intelligent films through the incorporation of grape skin and seed tannin extracts into gelatin
(Elsevier, 2022-09)
To achieve sustainability in the wine industry, by-products from winery operations are being diverted from waste streams and turned into beneficial use. Grape seed tannin (SeedT) and skin tannin (SkinT) extracts were 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 ...
