Chemistry of 4-dicyanomethylene-1,2,6-thiadiazines

Koutentis, Panayiotis Andreas; Rees, C. W. (2000)

The chlorine atoms in 3,5-dichloro-4-dicyanomethylene-1,2,6-thiadiazine 1 are readily displaced by thiophenols in the presence of Hünig's base, the first at -78 °C and the second at 20 °C to give the orange mono- and ...

The effect of aging and natural organic matter on the Th(OH)4 solubility

Prodromou, Melpomeni; Antoniou, Stella; Pashalidis, Ioannis (2014)

The solution chemistry of actinides, particularly hydrolysis, is of major importance in the design of nuclear waste repositories and in relation to nuclear fuel reprocessing cycles. In this study the formation and solubility ...

Experimental and theoretical studies on physico-chemical parameters affecting the solubility of phosphogypsum

Papanicolaou, F.; Antoniou, Stella; Pashalidis, Ioannis (2009)

Phosphogypsum is a waste by-product of the phosphate fertilizer industry, which is usually disposed in the environment because of its restricted use in industrial applications. Physico-chemical conditions existing in stack ...

Near-monodisperse α-hydroxy and α,ω-dihydroxy amine-based polymers: Synthesis and characterization

Costa, Costas N.; Patrickios, Costas S. (1999)

α-Hydroxy and α,ω-dihydroxy polymers of 2-(dimethylamino)ethyl methacrylate (DMAEMA) of various molecular weights were synthesized by group transfer polymerization (GTP) in tetrahydrofuran (THF), using 1-methoxy-1-(trime ...

Redox chemistry of sulphate and uranium in a phosphogypsum tailings dump

Papanicolaou, F.; Antoniou, Stella; Pashalidis, Ioannis (2010)

The present study aims to assess the effect of redox conditions existing within the tailings dump on the stability of phosphogypsum (e.g. sulphate reduction) and uranium(VI). Phosphogypsum sampling and in-situ measurements ...

Serum soluble interleukin-2 receptors in epithelial ovarian cancer patients

Pavlidis, Nicholas; Bairaktari, Eleni Th; Kalef-Ezra, J. A.; Nikolaides, C.; Seferiadis, C.; Fountzilas, George (1995)

The levels of soluble interleulkin-2 receptors (sIL-R2) were measured in the serum of 52 patients with epithelial ovarian carcinoma as well as in 25 age and sex-matched normal controls. The mean serum level of sIL-2R was ...

Study of copper sulfide crystallization in PEO-SDS solutions

Orphanou, M.; Leontidis, Epameinondas; Kyprianidou-Leodidou, Tasoula; Koutsoukos, Petros George; Kyriacou, Kyriacos C. (2004)

The crystallization of copper sulfide in aqueous supersaturated solutions in the presence of the polymer poly(ethylene oxide), PEO, and the surfactant sodium dodecyl sulfate, SDS, was investigated. In these systems, copper ...

Synthesis and aqueous solution characterization of catalytically active block copolymers containing imidazole

Simmons, M. R.; Patrickios, Costas S. (1998)

Article

Synthesis and aqueous solution characterization of catalytically active homopolymers, block copolymers and networks containing imidazole

Patrickios, Costas S.; Simmons, M. R. (2000)

Imidazole-containing polymers were prepared and characterized in terms of their hydrolytic activity. Unlike similar materials synthesized in the 1960s, the polymers are of precise molecular weight and controlled structure ...
