Surface Modification of Aqueduct Ceramics Induced by Nd:Yag Pulsed Laser Treatment
(Philadelphia, PA, USA: Old City Publishing, Inc, 2017)
The main aim of this paper is to present the results of the morphological and chemical changes on the surface of a ceramic sample irradiated by the Nd:YAG laser. The tested sample is a part of an aqueduct tile, originating ...
One-step conversion of ketones to conjugated acids using bromoform
(Synthetic Communications, 2009)
Phase-transfer-catalyzed (PTC) reactions of ketones with bromoform and aqueous lithium hydroxide in alcoholic solvent result in the formation of ,-unsaturated carboxylic acids. The reaction was performed at room temperature ...
Structural dissymmetrization of optically anisotropic Grs64±1Adr36±1Sps2 grandite from Meka Presedla (Kopaonik Mt., Serbia)
(Cambridge University Press, 2020)
In this paper, grandite core with Grs64±1Adr36±1Sps2 composition was crystallographically studied. This core represents zone A of the macroscopically visible five A–E zones of the optically anisotropic Grs58–64Adr36–42Sps2 ...
Examinations of cross-linked polyvinylpyridine in open reactor
(Materials Science Forum, 2005)
Macroporous cross-linked copolymer of 4-vinylpyridine and 25% (4:1) divinylbenzene is analyzed under open conditions, that is in a continuous well-stirred tank reactor (CSTR). With this aim the appropriate bifurcation ...
Manganese removal from water by magnesium enriched kaolinite-bentonite ceramics
(Taylor&Francis, 2012)
Manganese is frequently present at elevated concentrations in both surface and groundwater. In addition, manganese is a health hazard, highly soluble over a wide pH range and difficult to remove from the contaminated waters. ...
Aromaticity and conformational deformability of some environmental pollutants - methylated anthracenes
(Parlar Scientific Publications, 2014)
There is little information on methylated anthracenes which are constituents of diesel fuel. In this paper, a theoretical investigation of some molecular properties of methyl-anthracenes (MAs), 1-MA and 2-MA, and all ...
Ruby laser beam interaction with ceramic and copper artifacts
(Springer, 2010)
Preventive care, research, and restoration of cultural heritage objects requires multidisciplinary research and the involvement of experts of different profiles, using high technology equipment. Nondestructive methods ...
Chemical secretion and morpho-histology of the pygidial glands in two Palaearctic predatory ground beetle species: Carabus (Tomocarabus) convexus and C. (Procrustes) coriaceus (Coleoptera: Carabidae)
(Taylor & Francis Ltd, Abingdon, 2017)
Although all ground beetles have pygidial glands homologous in structure and function, there are many differences among species, often significant, in terms of chemical composition of the secretion and morphology of the ...
The effects of centrally applied ghrelin on appetite and metabolic parameters during aging
(Inst Materials Physics, 2014)
The main purpose of this study was to evaluate specifically, ingestive behavior and bloodborne indicators of metabolic status, after daily intracerebroventricular (ICV) ghrelin injections, in rats of different ages. Four ...
Dimethyldichlorosilane Hydrolysate as a Substitute for Cyclic Monomers in the Preparation of Functional Poly(siloxane)s
(Trans Tech Publications Ltd., 2004)
A number of carboxypropyl- terminated poly(siloxane)s were prepared using equilibration
polymerization reactions. Dimethyldichlorosilane hydrolysate, DDSH, was applied as a substitute
for the otherwise used cyclic siloxane ...
