Effects of the Water Matrix on the Degradation of Micropollutants by a Photocatalytic Ceramic Membrane.

The consumption of pharmaceuticals has increased the presence of micropollutants (MPs) in the environment. The removal and degradation of pharmaceutical mixtures in different water matrices are thus of significant importance. The photocatalytic degradation of four micropollutants-diclofenac (DCF), iopamidol (INN), methylene blue (MB), and metoprolol (MTP)-have been analyzed in this study by using a photocatalytic ceramic membrane.

Electrically induced liquid-liquid phase transition in water at room temperature.

In this work we expand on findings previously reported [Wexler et al., Phys. Chem.

Non-equilibrium thermodynamics and collective vibrational modes of liquid water in an inhomogeneous electric field.

In this experiment liquid water is subject to an inhomogeneous electric field (∇(2)Ea≈ 10(10) V m(2)) using a high voltage (20 kV) point-plane electrode system. Using interferometry it was found that the application of a strong electric field gradient to water generates local changes in the refractive index of the liquid, polarizes the surface and creates a downward moving electro-convective jet. A maximum temperature difference of 1 °C is measured in the immediate vicinity of the point electrode.
