The coordination ability of the hexaphosphinoylated p-tert-butylcalix[6]arene B6bL6 toward actinides is established, as well as its good separation ability of the actinide ions UO22+ and Th(IV) over trivalent rare earths such as La(III), Eu(III) ...
The importance of Fibre Reinforced Polymers (FRPs) as a material used for civil engineering purposes has grown in the last decade. Especially the introduction of pultrusion at an industrial level as a way to produce big batches of FRP made it possible to o ...
Liquid metal embrittlement (LME) of copper by liquid bismuth is investigated at 300◦C. It is shown that a very rapid damage is due to the synergy between the external stress and the phenomenon of intergranular penetration (IGP). Tests of IGP, i.e. without ...
Construction methods for steel-concrete structures have developed significantly over the last quarter of a century, and the number of steel-concrete bridges on road and rail networks is continually increasing. However, design methods for bridges have not e ...
Strut and tie models and stress fields are methods that can be used for the dimensioning and detailing of reinforced and prestressed concrete structures as well as for the check of existing ones. This paper presents an innovative approach towards the autom ...
Highly selective separation of yttrium (and lanthanides) is of interest for the design of radiopharmaceuticals, and an efficient method based on the ion-imprinting concept is proposed here. The synthesis and structural, thermodynamic and photophysical char ...
Computer-aided approaches for the efficient development of suitable stress fields are useful tools for the structural design of concrete structures. The paper describes a new procedure that is used within a previously proposed approach for the automatic ge ...

The stress field method is a technique based on the lower-bound theorem of plasticity that can be used for dimensioning, detailing and checking of structural concrete elements. Its use has been traditionally associated with the assumption of simplified (ri ...
Energies computed by B3LYP and other popular DFT functionals are flawed by systematic errors, which can become considerable for larger mols. These errors, predominately due to inadequacies in assessing longer-range non-bonded attractive effects, are illust ...
A quantum-mechanical model for quantum well polaritons in semiconductor microcavities is presented. The real and imaginary parts of the polariton dispersion are obtained. They represent, respectively, the position and the linewidth of the luminescence peak ...
