Alpha radiometry of uranium in surface and ground waters by liquid scintillation counting after separation of the radionuclide by cation exchange

Antoniou, Stella; Tsiaili, A.; Pashalidis, Ioannis (2008)

The alpha radioactivity of surface and ground water samples has been determined by liquid scintillation counting (LSC) after chemical preparation of the samples by cation exchange using the Chelex 100 resin. The method ...

Cationic amphiphilic model networks: Synthesis by group transfer polymerization and characterization of the degree of swelling

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

Group transfer polymerization (GTP) was applied to prepare model networks based on 2-(dimethylamino)ethyl methacrylate (DMAEMA) and methyl methacrylate (MMA). The flexibility of GTP allowed the synthesis of three isomeric ...

LQG optimality and separation principle for general discrete time partially observed stochastic systems over finite capacity communication channels

Charalambous, Charalambos D.; Farhadi, A. (2008)

This paper is concerned with control of stochastic systems subject to finite communication channel capacity. Necessary conditions for reconstruction and stability of system outputs are derived using the Information ...

Micellization behavior of poly(η-butyl methacrylate)-block-poly(2- (acetoacetoxy)ethyl methacrylate)

Sigel, R.; Krasia-Christoforou, T.; Below, I.; Schlaad, H. (2009)

A series of poly(η-butyl methacrylate)-block-poly(2-(acetoacetoxy)ethyl methacrylate)s (PBMA-b-PAEMA) were studied according to the formation of core-shell micelles in dilute cyclohexane solution (PBMA-shell, PAEMA-core). ...

A reductive-aggregation route to [Mn12O12(OMe) 2(O2CPh)16(H2O)2] 2- single-molecule magnets related to the [Mn12] family

Tasiopoulos, Anastasios J.; Wernsdorfer, W.; Abboud, K. A.; Christou, George (2004)

Axes of power: Jahn-Teller isomerism (that is, Jahn-Teller distortion along different axes) accounts for the presence of both faster and slower relaxing magnetization dynamics of the title compound (see core structure

Stereochemistry of the [4 + 2] cycloadditions of trans,trans- and cis,trans-2,4-hexadiene to C60

Chronakis, Nikos; Froudakis, G.; Orfanopoulos, Michael (2002)

The [4 + 2] cycloaddition of trans,trans-2,4-hexadiene with C60 proceeds via a concerted mechanism with retention of stereochemistry in the cycloadduct 1a. However, when cis,trans-2,4-hexadiene reacts with C60, isomerization ...
