Fibre formation in calcium caseinate influenced by solvent isotope effect and drying method – A neutron spectroscopy study

We present an investigation of the dynamics of calcium caseinate as a function of hydration, solvent isotope (H₂O and D₂O) and drying methods (roller drying and spray drying), using quasi-elastic neutron scattering (QENS). These factors are key to the formation of fibres in this material which makes it a potential...

Hot balls dry sludge

Each year some 25 million m3 of mineral sludge are dredged from rivers, canals and harbours in the Netherlands alone, twenty percent of which is polluted. The unpolluted sludge is usually dumped at sea. The remaining five million m3 may only be dumped in a few selected landfill locations, at considerable cost.A sludge flock, hotographed at the...
