Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Elsevier Ltd, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Supercapacitive Performances of Activated Highly Microporous Natural Carbon Macrofibers
(Electrochemical Soc Inc, Pennington, 2017)
Activated carbons with high specific surface area (even above 2000 m(2) g(-1)) and pronounced microporosity are prepared in two-stage process involving conventional carbonization of waste hemp fibers and subsequent activation ...
Impregnation of corona modified polypropylene non-woven material with thymol in supercritical carbon dioxide for antimicrobial application
(Elsevier Science Bv, Amsterdam, 2015)
This study discusses the possibility of impregnation of polypropylene (PP) and corona modified PP non-woven material with thymol in supercritical solvent in order to fabricate eco-friendly antimicrobial textile material. ...
Gentamicin-Loaded Bioactive Hydroxyapatite/Chitosan Composite Coating Electrodeposited on Titanium
(Amer Chemical Soc, Washington, 2018)
Composite coating of antibiotic gentamicin (Gent), natural polymer chitosan (CS), and hydroxyapatite (HAP) was successfully assessed by applying the electrophoretic deposition (EPD) technique. EPD was performed under ...
Modelling current efficiency in an electrochemical hypochlorite reactor
(Elsevier, Amsterdam, 2015)
A mathematical model was set up for anodic, cathodic and overall current efficiencies of an electrochemical cell for hypochlorite production acting as an ideal stirred reactor. A 0.06-0.20 mol dm(-3) NaClO hypochlorite ...
The removal of Zn2+, Pb2+, and As(V) ions by lime activated fly ash and valorization of the exhausted adsorbent
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
This study focuses on the use of raw fly ash (FA) and modified fly ash - activated by lime (MFA), as effective and low-cost adsorbents for the removal of heavy metals (Zn2+, Pb2+ and As(V)), followed by the revalorization ...
Tailoring the physico-chemical and antimicrobial properties of agar-based films by in situ formation of Cu-mineral phase
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
New agar-based composite films with increasing Cu-carbonate and Cu-phosphate mineral phase content were prepared by in situ mineralization and solvent casting method. SEM and optical analysis revealed that Cu-carbonate ...
Chitosan-based hydrogel wound dressings with electrochemically incorporated silver nanoparticles - In vitro study
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this work, we provide a facile path for the preparation of wound dressing materials with improved characteristics based on biocompatible chitosan and poly(vinyl alcohol) hydrogels with embedded silver nanoparticles ...
Supercritical CO2 impregnation of PLA/PCL films with natural substances for bacterial growth control in food packaging
(Elsevier Science Bv, Amsterdam, 2018)
Biodegradable polymers with antibacterial properties are highly desirable materials for active food packaging applications. Thymol, a dietary monoterpene phenol with a strong antibacterial activity is abundant in plants ...
In vitro investigation of electrophoretically deposited bioactive hydroxyapatite/chitosan coatings reinforced by graphene
(Elsevier Science Inc, New York, 2017)
Graphene (Gr) and natural polymer chitosan (CS) were introduced to hydroxyapatite (HAP) to produce a three-component composite coating, which was fabricated by cathodic electrophoretic deposition on Ti substrates in an ...
