Nano- and Micro-Scale Surface Modification of FCC Metal Using High Submerged Cavitating Water Jet
(Springer, New York, 2013)
The aim of this paper is to establish a possible application of the cavitation phenomenon as an efficient method to modify surface properties at the nano and micro levels. Commercial-purity copper was subjected to high ...
Mica based coating for application in lost foam casting process
(Editura Stiintifica Fmr, Bucharest, 2012)
This paper presents the results of mechanical activation of filler based on mica and the influence on the quality of foundry coatings. The coating was applied for lining of evaporable model in Lost foam casting process. ...
Pretreatment of used vegetable oil using CaO and CaO-ZnO for biodiesel production
(Czech Society of Chemical Engineering, 2014)
Green pH- and magnetic-responsive hybrid hydrogels based on poly(methacrylic acid) and Eucalyptus wood nanocellulose for controlled release of ibuprofen
(Cellulose, 2021)
pH- and magnetic-sensitive hybrid hydrogels based on poly(methacrylic acid) (PMAA), nanocellulose (NC), carboxymethyl cellulose (CMC) and magnetite particles (MN) were prepared as ibuprofen delivery system. NC was isolated ...
Covalently immobilized lipase catalyzing high-yielding optimized geranyl butyrate synthesis in a batch and fluidized bed reactor
(Elsevier, Amsterdam, 2012)
Three commercially available polymers (Sepabeads (R) EC-EP, Sepabeads (R) EC-HA and Purolite (R) A-109) were tested for potential application as supports for covalent immobilization of lipase from Candida rugosa by analyzing ...
Function of the microbiota
(Elsevier Sci Ltd, Oxford, 2013)
The gut microbiota of humans is complex but stable in composition and function. Metabolic conversions performed by the members of the microbiota yield both beneficial and hazardous compounds, and have a systematic impact ...
Surface structural heterogeneity of high power plasma-sprayed hydroxyapatite coatings
(Elsevier Science Sa, Lausanne, 2016)
The aim of this work was to examine the dependence of the local surface structure (surface structural heterogeneity) on the local thickness (thickness uniformity) and structure properties along the thickness of hydroxyapatite ...
Modelling of the substance transfer in the gas-liquid system with chemical reaction
(Petroleum and Coal, 2012)
In this paper substance transfer phenomena in the multistage reactive system were investigated.Substance transfer between liquid and gas phases in a distillation packed column with reactionesterification was examined. ...
Modeling of Fischer-Tropsch Product Distribution over Fe-based Catalyst
(Aidic Servizi Srl, Milano, 2013)
The kinetic models of Fischer-Tropsch synthesis (FTS) product distribution can be classified into two major groups: hydrocarbon selectivity models and detailed Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetic models. In ...
A novel method to mitigate the top of the line corrosion in wet gas pipelines by corrosion inhibitor within a foam matrix
(Corrosion 2012, 2012)
Top of the Line Corrosion (TLC) has been a serious issue for the Oil & Gas industry. Conventional inhibition techniques are expensive and often do not seem to provide enough protection to the steel surface at the top of ...
