The combined extraction of sage (Salvia officinalis L.): Ultrasound followed by supercritical CO2 extraction
(Elsevier Science Bv, Amsterdam, 2011)
A wide spectrum of phytochemicals could be isolated from sage (Salvia officinalis L) using different extraction or distillation technique: the supercritical fluid extraction (SFE), the volatiles compounds (monoterpenes and ...
Preparation and characterization of bismuth germanium oxide (BGO) polymer composites
(Elsevier Science Sa, Lausanne, 2017)
Bismuth germanium oxide Bi12GeO20 (BGO) has very interesting electrical, optical and magnetic properties. In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. ...
Functionalization of cotton with poly-NiPAAm/chitosan microgel. Part I. Stimuli-responsive moisture management properties
(Springer, Dordrecht, 2012)
Stimuli-responsive microgel, based on synthetic polymer (poly-NiPAAm) and biopolymer (chitosan), was incorporated onto cotton fabric surface by pad-dry-cure method using 1,2,3,4-butanetetracarboxylic acid (BTCA) as ...
Functionalization of cotton with poly-NiPAAm/chitosan microgel: Part II. Stimuli-responsive liquid management properties
(Springer, Dordrecht, 2012)
An innovative strategy for functional finishing of cotton involves application of stimuli-responsive surface modifying system based on temperature- and pH-responsive poly-NiPAAm/chitosan microgel. The stimuli-responsiveness ...
Selective magnetic GMA based potential sorbents for molybdenum and rhenium sorption
(Elsevier Science Sa, Lausanne, 2017)
Magnetic macroporous crosslinked copolymer glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA) samples with different magnetite content were prepared by suspension copolymerization and functionalized ...
Continuous biodiesel production under subcritical condition of methanol - Design of pilot plant and packed bed reactor with MnCO3/Na-silicate catalyst
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
The continuous biodiesel production from soybean oil was carried out under the subcritical condition of methanol with MnCO3/Na-silicate as a heterogeneous catalyst. The transesterification rate was first investigated in a ...
Rome Foundation Working Team Report on Post-Infection Irritable Bowel Syndrome
(W B Saunders Co-Elsevier Inc, Philadelphia, 2019)
BACKGROUND & AIMS: The existence of postinfection irritable bowel syndrome (PI-IBS) has been substantiated by epidemiology studies conducted in diverse geographic and clinical settings. However, the available evidence has ...
Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
Novel modified nanocellulose applicable as reinforcement in high-performance nanocomposites
(Elsevier Sci Ltd, Oxford, 2017)
The influence of modification and vacuum/supercritical CO2 (scCO(2)) drying methods on the surface properties, morphology and thermal stability of cellulose nanocrystals (NC) was presented in this study. Introduction of ...
Fischer-Tropsch synthesis product selectivity over an industrial iron-based catalyst: Effect of process conditions
(Elsevier Science Bv, Amsterdam, 2016)
The effect of process conditions on product selectivity of Fischer-Tropsch synthesis (FTS) over industrial iron-based catalyst (100 Fe/5 Cu/4.2 K/25 SiO2) was studied in a 1-L stirred tank slurry reactor. Experiments were ...
