Hydrophobization and Photo-Stabilization of Radiata Pinewood: The Effect of the Esterification on Thermal and Mechanical Properties
(MDPI, 2020-10-24)
Wood protection through chemical modification has received increasing interest over the last decades due to the environmental issues related to conventional biocides or protecting products. Consequently, a wide range of ...
Recovery of Bioactive Compounds from Hazelnuts and Walnuts Shells: Quantitative–Qualitative Analysis and Chromatographic Purification
(MDPI, 2020-09-24)
Hazelnut (HS) and walnut (WS) shells, an abundant by-product of the processing industries of these edible nuts, are traditionally considered as a low-value waste. However, they are a source of valuable compounds with an ...
Thermochemical and Mechanical Properties of Pine Wood Treated by In Situ Polymerization of Methyl Methacrylate (MMA)
(MDPI, 2020-07-17)
The impregnation of low-molecular-weight monomers prior to polymerize them inside the wood may be an efficient way to improve some important wood properties. This work aimed to determine some technological properties of ...
Lignins from Agroindustrial by-Products as Natural Ingredients for Cosmetics: Chemical Structure and In Vitro Sunscreen and Cytotoxic Activities
(MDPI, 2020-03-03)
The growing concern about the environmental impact and human health risk related to the excessive use of synthetic ingredients in cosmetics and topical formulations calls for the exploration of safe and sustainable natural ...
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 ...
Base catalysed depolymerization of lignin: Influence of organosolv lignin nature
(2014-07)
Three different lignins obtained from olive tree pruning by organosolv processes
(acetosolv, formosolv and acetosolv/formosolv) were depolymerized by alkaline hydrolysis in a batch reactor to produce high value added ...
Economic analysis of a biorefinery process for catechol production from lignin
(Elsevier, 2018-10)
Recently, the valorization of the lignin fraction in the biorefinery scheme is getting more and more attention as the use of this component for the production of bio-based chemicals is crucial for the success of the integral ...
Antioxidant activity of phenolic compounds obtained by autohydrolysis of corn residues
(2012-03)
This study aimed to evaluate the effect of autohydrolysis temperature of corn residues in the antioxidant
activity of the phenolic compounds extracted from the liquid phase. The treatments were carried out at
160, 180, ...
Assessment of green approaches for the synthesis of physically crosslinked lignin hydrogels
(Elsevier, 2019-09-28)
Lignin is an excellent candidate to be used as a starting material for hydrogel synthesis due to its highly functional character. The exhaustible character of the fossil resources linked to the increase of plastic residues ...
