The development of a combined enzymatic and microbial fermentation as a viable technology for the spent coffee ground full utilization
(Biomass Conversion and Biorefinery, 2023)
This study demonstrated the innovative biotransformation aspect of spent coffee grounds (SCG) by application of the specific enzymatic cocktail with addition of lactic acid bacteria strain Lactobacillus rhamnosus (ATCC (R) ...
New copper (II) complexes derived from azo pyridone dyes: Structure characterization, thermal properties, and molecular docking studies
(John Wiley and Sons Ltd., 2023)
Two azo dye ligands, bearing different substituents (chlorine atom or methoxy group) in the para-position of the phenyl ring, were employed for the synthesis of two Cu(II) chelates. Full structural affirmation of complexes ...
Use of chènevotte, a valuable co-product of industrial hemp fiber, as adsorbent for copper ions: Kinetic studies and modeling
(Elsevier B.V., 2022)
In this study, a series of hemp shives (chènevotte) with different chemical compositions and properties, namely a raw (SHI-R), a washed with water (SHI-W), three samples chemically modified with KOH (SHI-OH), Na2CO3 (SHI-C) ...
Dispersive Solid–Liquid Microextraction Based on the Poly(HDDA)/Graphene Sorbent Followed by ICP-MS for the Determination of Rare Earth Elements in Coal Fly Ash Leachate
(MDPI, 2022)
A dispersive solid-phase microextraction (DSPME) sorbent consisting of poly(1,6-hexanedi-ol diacrylate)-based polymer microspheres, with embedded graphene microparticles (poly(HDDA)/g-raphene), was synthesized by microfluidic ...
Extraction of lyophilized olive mill wastewater using supercritical CO2 processes
(Alexandria Engineering Journal, 2022)
The olive growing in Tunisia has an economic dominance and agricultural importance. However, the huge extraction of olive oil generates a large quantity of olive mill wastewater (OMW), which is discharged to the surroundings. ...
The influence of cobalt loading on electrocatalytic performance toward glucose oxidation of pillared montmorillonite-supported cobalt
(Elsevier B.V., 2022)
In this paper, the influence of cobalt loading in pillared clay-supported cobalt materials on their electrocatalytic performance toward glucose oxidation was investigated. A series of aluminum-pillared montmorillonite clay ...
Antimicrobial Nanocomposites Based on Oxidized Cotton Fabric and in situ Biosynthesized Copper Oxides Nanostructures Using Bearberry Leaves Extract
(Korean Fiber Society, 2022)
The aim of this study was to develop antimicrobial nanocomposite textile material comprising of Cu-based nanostructures synthesized on oxidized cotton fabric using Arctostaphylos uva-ursi (L.) Spreng., Ericaceae (bearberry ...
Novel Biocomposite Films Based on High Methoxyl Pectin Reinforced with Zeolite Y for Food Packaging Applications
(Foods, 2022)
Pectin is a natural biopolymer with broad applications in the food industry and it is suitable to prepare edible films to prolong food shelf-life. However, the main limitation of pectin-based films is their poor mechanical ...
Continuous production of fructo-oligosaccharides using selectively immobilized fructosyltransferase from Aspergillus aculeatus onto Purolite® A109
(Korean Society of Industrial Engineering Chemistry, 2023)
Within this study, the investigation of potential selective immobilization of fructosyltransferase (FTase) derived from Aspergillus aculeatus (from commercial enzyme preparation Pectinex® Ultra SP-L) onto the polystyrenic ...
Determination of Mechanical Properties of Epoxy Composite Materials Reinforced with Silicate Nanofillers Using Digital Image Correlation (DIC)
(MDPI, 2022)
In this study, silicate nanofillers; dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite; were synthesized using four different methods and incorporated into the epoxy resin to improve its mechanical ...
