(2022-03-19)
La contamination de l'eau par de nombreuses formes de polluants tels que les composés organiques volatils (COV), les colorants synthétiques et les métaux lourds peuvent endommager notre planète et posent un problème pour ...
Electrochemical Activity of Lignin Based Composite Membranes
(MDPI, 2021-02-21)
Our society’s most pressing challenges, like high CO2 emission and the constant battle against energy poverty, require a clean and easier solution to store and utilize the renewable energy resources. However, recent ...
Lignin-Based Polyols with Controlled Microstructure by Cationic Ring Opening Polymerization
(MDPI, 2021-02-22)
Lignin-based polyols (LBPs) with controlled microstructure were obtained by cationic ring opening polymerization (CROP) of oxiranes in an organosolv lignin (OL) tetrahydrofuran (THF) solution. The control on the microstructure ...
Effect of gelatin concentration, ribose and glycerol additions on the electrospinning process and physicochemical properties of gelatin nanofibers
(Elsevier, 2022-11)
Rheological properties of gelatin-based solutions containing different concentrations of ribose and/or glycerol were assessed before electrospun mats were manufactured and their properties investigated. Characterization ...
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 ...
Advanced heterogeneous catalytic systems for biofuels production derived from HMF
