River water is an important source of Dutch drinking water. For this reason, continuous monitoring of river water quality is needed. However, comprehensive chemical analyses with high-resolution gas chromatography [GC]-mass spectrometry [MS]/liquid c

A mechanism is suggested which can modify in certain cases the Goodenough-Kanamori-Anderson rules determining the character of superexchange in magnetic insulators; namely, side groups coupled to ligands, which are often present but are usually ignor

Recently magnetic order has been found in organometallic donor (D)-acceptor (A) compounds, with a localized spin on a transition-metal ion (donor) and a localized spin on an organic group (acceptor). We call these magnetic d/p systems. The magnetic o

The heat capacities of some liquid alkali-lead and alkali-tin alloys exhibit anomalous behaviour as a function of bath composition and temperature. The equiatomic composition is characterized by a large excess heat capacity which depends strongly upo

In this paper we discuss the exchange interaction between two magnetic ions in the limit of very large on-site Coulomb interactions. We find that in this limit the exchange interaction is due to fundamental principles of quantum mechanics: the differ

Liquid alloys, which are disordered systems in the sense of having no long range atomic or magnetic order, display a remarkable variety of local atomic structures. The richness of this variety has become apparent in recent years with advances in ex

Polymer-water partition coefficients (Kpw) of hexachlorobenzene, 41 polychlorinated biphenyls (PCBs), and 26 polyaromatic hydrocarbons (PAHs) were determined for low-density polyethylene (LDPE) and five different silicone rubbers. Partition coefficie

We discuss the resistivity, thermopower and Knight shift as a function of temperature and composition for a number of alkali-IV A metal alloys using the tight binding C.P.A. model. Elastic electronph0n0n interaction results in a strong temperature de

The equiatomic alkali-group-IV (Si,Ge,Sn,Pb) compounds usually crystallize in the NaPb structure. This structure contains negatively charged tetrahedra of group-IV ions, which are separated by alkali ions. The Li compounds, however, have either a CsC
