Delamination detection in woven composite laminates with embedded optical fibers
(Wiley-VCH Verlag Gmbh, Weinheim, 2001)
Predicting liquid chromatography−electrospray ionization/mass spectrometry signal from the structure of model compounds and experimental factors; case study of aripiprazole and its impurities
(Elsevier B.V., 2023)
A priori estimation of analyte response is crucial for the efficient development of liquid chromatography–electrospray ionization/mass spectrometry (LC–ESI/MS) methods, but remains a demanding task given the lack of knowledge ...
Influence of structural changes induced by oxidation and addition of silver ions on electrical properties of cotton yarn
(Editura Acad Romane, Bucuresti, 2014)
This paper is focused on investigating the electrical behavior of cotton yarn oxidized with nonselective oxidation agent, hydrogen peroxide, through measurement of structural changes in cotton, and elucidating the influence ...
Magneli phase titanium oxides as catalyst support - Electrochemical behavior of Ebonex/Pt catalysts
(Journal of New Materials for Electrochemical Systems, 2006)
The impregnation method has been applied to synthesize platinum nanoparticles on Magneli phase titanium oxide powder (Ebonex). Surface area of the Ebonex support was determined by BET technique. Distribution and morphology ...
Evaluation of the antibacterial effectiveness of novel copper/polypyrrole nanocomposite
(Elsevier B.V., 2023)
A novel and effective antibacterial agent based on a combination of copper nanoparticles (CuNPs) and polypyrrole (PPy) is presented. By using a straightforward in situ polymerization method in water, a copper/polypyrrole ...
Gas holdup in a gassed reciprocating plate column with Rashig rings placed in interplate spaces
(Canadian Society for Chemical Engineering, 2002)
The gas holdup is studies in a gassed reciprocating plate column with the addition of the Rashig rings placed in each interplate space. The gas holdup generally increases with increasing the vibration speed, the superficial ...
Preparation and characterization of pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
(Wiley-Blackwell, Hoboken, 2011)
Novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid were prepared in two steps. Chitosan was first ionically crosslinked with itaconic acid, after which a free radical polymerization and ...
Influence of an antimicrobial treatment on the strength properties of polyamide/elastane weft-knitted fabric
(Wiley, Hoboken, 2007)
Polyamide/elastane weft-knitted fabric, as a suitable compression material, was treated with gentamicin sulfate and a natural antimicrobial preparation of the autochthonous essential oil of Picea abies. The antimicrobial ...
Partitioning of particulate matter and elements of suburban continental aerosols between fine and coarse modes
(Springer Heidelberg, Heidelberg, 2018)
The results presented in this work demonstrate for the first time a distribution of elements in the spectral analysis of aerosols in the suburban continental Balkan Peninsula. Samples were collected in the suburban area ...
Micromechanical assessment of mismatch effects on fracture of high-strength low alloyed steel welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Fracture of steel welded joints produced with one or two weld metals is analysed; the latter (double mismatched) consist of overmatched and undermatched portion. Specimens with a pre-crack in the symmetry plane of each ...
