Bio-Degradable Polyurethane Foams Produced by Liquefied Polyol from Wheat Straw Biomass
(MDPI, 2020)
In the present work, an abundant and unused residue (wheat straw) has been employed to synthesize a polyol as a substituent of castor oil in polyurethane foams. The liquefied product showed excellent properties for the ...
Nanohybrid Layered Double Hydroxides Used to Remove Several Dyes from Water
(MDPI, 2019)
For the preparation and characterization of several layer double hydroxides (LDH) with inorganic interlayer anions (carbonate and nitrate) and nanohybrids, two organo-LDHs were studied in detail. The dodecylbenzene sulfonate ...
Mechanochemical Preparation of Novel Polysaccharide-Supported Nb2O5 Catalysts
(MDPI, 2019)
Polysaccharides extracted from natural sources can be used as starting material for the preparation of nanoparticle supported composites. A novel family of bio-nanocomposites was mechanochemically synthesized by using ...
Nanocellulose-Based Inks—Effect of Alginate Content on the Water Absorption of 3D Printed Constructs
(MDPI, 2019)
2,2,6,6-tetramethylpyperidine-1-oxyl (TEMPO) oxidized cellulose nanofibrils (CNF) were used as ink for three-dimensional (3D) printing of porous structures with potential as wound dressings. Alginate (10, 20, 30 and 40 ...
Cellulose Nanofibers and Other Biopolymers for Biomedical Applications. A Review
(MDPI, 2019)
Biopolymers are materials synthesised or derived from natural sources, such as plants, animals, microorganisms or any other living organism. The use of these polymers has grown significantly in recent years as industry ...
Horticultural Plant Residues as New Source for Lignocellulose Nanofibers Isolation: Application on the Recycling Paperboard Process
(MDPI, 2020)
Horticultural plant residues (tomato, pepper, and eggplant) were identified as new sources for lignocellulose nanofibers (LCNF). Cellulosic pulp was obtained from the different plant residues using an environmentally ...
Optimum Particle Size of Treated Calcites for CO2 Capture in a Power Plant
(MDPI, 2019)
This work has analyzed the influence of the particle size of a calcite from a quarry, whether original, calcined, or rehydrated, on the efficiency of CO2 capture of the gases emitted in a coal-fired power plant. Three ...
Valorization of Hemp Core Residues: Impact of NaOH Treatment on the Flexural Strength of PP Composites and Intrinsic Flexural Strength of Hemp Core Fibers
(MDPI, 2020)
Hemp core is a lignocellulosic residue in the production chain of hemp strands. Huge amounts of hemp core are gathered annually in Europe (43,000 tons) with no major application end. Such lignocellulosic wastes have potential ...
Synthesis and Characterization of Aero-Eutectic Graphite Obtained by Solidification and Its Application in Energy Storage: Cathodes for Lithium Oxygen Batteries
(MDPI, 2020)
Aero-eutectic graphite can be defined as a new light material with hierarchically structured porosity. It is obtained from the solidification of gray cast irons, followed by the dissolution of the ferrous matrix by an ...
Improvement of the Concrete Permeability by Using Hydrophilic Blended Additive
(MDPI, 2019)
Crystalline hydrophilic additives are increasingly used as efficient methods for reducing water permeability in concrete. Their effectiveness in hindering water penetration has been proven in different cementitious materials, ...
