Comparison of hydrocarbon-degrading consortia from surface and deep waters of the eastern mediterranean sea: Characterization and degradation potential
(2021)The diversity and degradation capacity of hydrocarbon-degrading consortia from surface and deep waters of the Eastern Mediterranean Sea were studied in time-series experiments. Microcosms were set up in ONR7a medium at in ... -
Coupled FEA Model with Continuum Damage Mechanics for the Degradation of Polymer-based coatings on Drug-Eluting Stents
(2021)Drug-Eluting Stents (DES) are commonly used in Coronary angioplasty procedures to reduce the phenomenon of restenosis. Numerical simulations are proven to be a useful tool to the Bioengineering community in computing the ... -
Decolorization and degradation of reactive azo dyes via heterogeneous photocatalytic processes
(2010)Reactive dyes are extensively used in textile industry in the last years due to their superior performance, but they are environmentally hazardous and difficult to treat effectively by classical methods. In the present ... -
Degradation of perfluorinated sulfonic acid films: An in-situ infrared spectro-electrochemical study
(2009)The in-situ Fourier transform infrared (FTIR) spectro-electrochemical method was used to evaluate the degradation mechanism of perfluorinated sulfonic acid (PFSA) polymer for the first time. The effect of H 2O 2 concentration ... -
Enhanced Ultrasonic-Assisted Heterogeneous Fenton Degradation of Organic Pollutants over a New Copper Magnetite (Cu-Fe3O4/Cu/C) Nanohybrid Catalyst
(2020)A copper magnetite nanohybrid catalyst (Cu-Fe3O4/Cu/C), abundant of Schottky interfaces and structural defects, with ultrathin encapsulation of graphitic carbon, was synthesized and tested. The catalyst shows enhanced ... -
Fatigue reliability predictions in vibrating structures under uncertainty
(2008)This work addresses the problem of predicting the reliability due to fatigue of MDOF structures subjected to uncertain random loading. Uncertainties in loading characteristics as well as in structural and degradation models ... -
FEA of Drug-Eluting Stents and Sensitivity Analysis of a Continuum Damage Model for the Degradation of PLGA Coating
(2021)Drug-Eluting Stents (DES) are commonly used in coronary angioplasty operations as a solution against artery stenosis and restenosis. Computational Bioengineering allows for the in-silico analysis of their performance. The ... -
Heterojunction architecture of pTTh nanoflowers with CuOx nanoparticles hybridized for efficient photoelectrocatalytic degradation of organic pollutants
(2020)Herein, resulting from the heterojunction engineering, poly-terthiophene (pTTh) hybridized CuOxnanoparticles (abbreviated as CuOx@pTTh) are firstly synthesized and adopted as a promising photoelectrocatalyst for phenol ... -
Investigation on the protective role of local AL cladding against corrosion damage and hydrogen embrittlement of 2024 aluminum alloy specimens
(2004)The present investigation aims to inquire whether Al cladding of 2024 aluminum alloy specimens could provide, additionally to the expected protection against corrosion damage, also a protection against the corrosion induced ... -
Leaching of the organophosphorus nematicide fosthiazate
(2007)Fosthiazate is an organophosphorus nematicide which was recently included in Annex I of the Directive 91/414/EEC under the clause that it should be used with special care in soils vulnerable to leaching. Thus, the leaching ... -
Medium-density fibreboards bonded with phenol-formaldehyde resin and calcium lignosulfonate as an eco-friendly additive
(2021)The potential of addition of calcium lignosulfonate as an eco-friendly additive with a phenol-formaldehyde (PF) resin, at different ratios, to produce medium-density fibreboards (MDF) with acceptable properties, was ... -
Novel biomixtures based on local Mediterranean lignocellulosic materials: Evaluation for use in biobed systems
(2010)The composition of biomixtures strongly affect the efficacy of biobeds. Typically, biomixture consists of peat (or compost), straw (SIR) and topsoil (1:2:1 by volume). Straw guarantees a continuous supply of nutrients and ... -
Performance analysis of a grid-connected photovoltaic park after 6 years of operation
(2019)The growth of renewable energy and especially photovoltaic energy in Greece is remarkable. There exist many grid-connected systems in Greek territory which have completed ten years operation. A challenging task for these ... -
Persistence and efficacy of spinetoram against three major stored grain beetle on wheat
(2015)The insecticidal efficacy of spinetoram at concentrations of 0.1, 1 and 5 ppm on wheat was investigated against adults of three major stored-grain species, Sitophilus oryzae (L), Rhyzopertha dominica (F.) and Tribolium ... -
Quantifying the overhead due to routing probes in multi-rate WMNs
(2010)The selection of high-throughput routes is a key element towards improving the performance of wireless multihop networks. While several routing metrics have been proposed in the literature, it has been shown that link-quality ... -
