Quantitative comparison of iron and cobalt based catalysts for the Fischer-Tropsch synthesis under clean and poisoning conditions
(Elsevier, Amsterdam, 2020)
Quantitative data comparing iron and cobalt based catalysts for the Fischer-Tropsch synthesis (FTS) are scarce due to the fact that these two kinds of catalysts typically utilize different process conditions. This paper ...
Fabrication of bacterial cellulose-based wound dressings with improved performance by impregnation with alginate
(Elsevier, Amsterdam, 2020)
Bacterial cellulose (BC) hydrogels are among the most efficient materials already being used for the treatment of complex wounds. The moist environment provided by the BC dressing is a key feature assuring efficient wound ...
Prediction of interphase drag coefficient and bed expansion using a variational model for fluidization of small spherical particles
(Elsevier Science Inc, New York, 2020)
In this study, we applied the variational model to fluidization of small spherical particles. Fluidization experiments were carried out for spherical particles with 13 diameters between d(p) = 0.13 and 5.00 mm. We propose ...
Adsorption performances and antimicrobial activity of the nanosilver modified montmorillonite clay
(Desalination Publ, Hopkinton, 2020)
The synthesis and adsorption potential of Cy-npAg, obtained by modification of raw montmorillonite clay (raw-Cy) with silver nanoparticle (npAg), was studied in this work. Optimization procedure, with respect to time, ...
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 ...
Synthesis of nano-crystalline NiFe2O4 powders in subcritical and supercritical ethanol
(Elsevier Science Bv, Amsterdam, 2016)
Nano-crystalline nickel ferrite has a broad range of applications due to its favourable magnetic properties. Those characteristics can be significantly influenced by the synthesis pathway including methods conducted in the ...
A detailed UV-Vis spectral investigation of six azo dyes derived from benzoic- and cinnamic acids: experimental and theoretical insight
(Comptes Rendus Chimie, 2021)
Six donor-pi-acceptor azo dyes, with altered donor- (p-hydroxyphenyl-and naphthalene-2ol) and carboxylic based acceptor groups, were subjected to detailed solvatochromic and tautomeric investigation in different environments ...
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 ...
Hybrid material based on subgleba of mosaic puffball mushroom (Handkea utriformis) as an adsorbent for heavy metal removal from aqueous solutions
(Journal of Environmental Management, 2021)
The alkali treated subglebal tissue of the mosaic puffball (Handkea utriformis) (Sa) and Sa modified with hydroxyapatite (Sa-HAp), obtained by successive ionic layer adsorption and reaction (SILAR) method, were used for ...
Volumetric properties of binary mixtures of tetrahydrofuran, dimethyl adipate, 1-butanol and 2-butanol from (288.15 to 323.15) K and modeling by Prigogine-Flory-Patterson (PFP) and Extended Real Association Solution (ERAS) models
(Journal of Molecular Liquids, 2021)
In this work, experimental densities data of the binary system tetrahydrofuran + 2-butanol have been determined at eight temperatures, T=(288.15-323.15) K and atmospheric pressure and used for excess molar volume calculations. ...
