Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier Sci Ltd, Oxford, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT-IR, H-1 and C-13 NMR, UV-Vis, and PL spectroscopy. Photophysical properties of the dyes were ...
Electrokinetic and sorption properties of hydrogen peroxide treated flax fibers (Linum usitatissimum L.)
(Cellulose, 2021)
Hydrogen peroxide represents an ecologically and economically acceptable agent for bleaching of flax fibers. The influence of hydrogen peroxide treatment under different conditions, i.e. hydrogen peroxide concentrations ...
Effect of plasma treatment on chemical composition, structure and sorption properties of lignocellulosic hemp fibers (Cannabis sativa L.)
(Elsevier Sci Ltd, Oxford, 2020)
Hemp fibers with different amount of hemicelluloses and lignin were subjected to atmospheric pressure dielectric barrier discharge under different conditions (40 W and 80 W power of discharge, const. time 120 s) in order ...
Twin nucleation from a single lt c plus a > dislocation in hexagonal close-packed crystals
(Acta Materialia, 2021)
Twinning plays an important role in governing the balance between strength and ductility in hexagonal-close-packed (HCP) metals. Here, we report a combined experimental and theoretical study of twin nucleation from a single ...
Hybrid acrylic nanocomposites with excellent transparency and hardness/toughness balance
(Elsevier B.V., 2020)
The composite nanofibers were used as reinforcement in acrylic polymer for the overall enhancement of thermo-mechanical properties, adhesion between fibers and matrix, and fracture toughness of the final nanocomposite since ...
Core–shell carbon fiber@Co1.5Mn1.5O4 mesoporous spinel electrode for high performance symmetrical supercapacitors
(Elsevier B.V., 2020)
We report a mesoporous composite system consisting of carbon fiber cores surrounded with Co1.5Mn1.5O4 spinel nanocrystal shells, synthesized by a simple two-step process involving single-nozzle co-electrospinning and ...
The effect of cesium dopant on APCVD graphene coating on copper
(Elsevier, Amsterdam, 2020)
This study reports in-situ cesium-doped graphene (G/Cs) coating obtained by introducing Cs2CO3 into the atmospheric pressure chemical vapor deposition (APCVD) furnace during graphene deposition on copper. The successful ...
The chitosan-based bioactive composite coating on titanium
(Elsevier B.V., 2021)
This paper describes a promising electrophoretic deposition (EPD) approach for developing composite coatings based on chitosan with the additional components of hydroxyapatite, graphene, and gentamicin on titanium substrate. ...
Old Plant, New Possibilities: Wild Bilberry (Vaccinium myrtillus L., Ericaceae) in Topical Skin Preparation
(Antioxidants, 2021)
Bilberry represents a valuable source of antioxidant substances responsible for its application for the treatment of different conditions (such as inflammation, cardiovascular disease, cancer, diabetes, and different ...
Recommendations for replacing PET on packaging, fiber, and film materials with biobased counterparts
(Green Chemistry, 2021)
This review sheds light on urgent questions that arise from the need to replace a polymer resin,-poly(ethylene terephthalate), which represents 7.7% market-share in the global plastic demand (Plastics-the Facts 2019), by ...
