Solid state transformations of (NH4, Pb)-clinoptilolite through heating
, 2018 Three clinoptilolite-based materials, having Pb2+/NH4+ ratios of 1.60, 0.56 and 0.16, were prepared starting from a powder containing ≈90% of NH4-clinoptilolite. The samples were submitted to a set of thermal treatments of 2 hours up to 1000 °C.

Reorientational Motions and Ionic Conductivity in (NH4)2B10H10 and (NH4)2B12H12
, 2018 We investigated molecular dynamics in two ammonium borane systems from the group of promising ion conductors. The investigation was performed by means of 1H and 11B NMR spectroscopy and spin-lattice relaxation techniques.

Photoluminescence enhancement of (NH4)(2)S-x passivated InP surface by rapid thermal annealing
, 1996 Photoluminescence enhancement of (NH4)(2)S-x passivated InP surface followed by rapid thermal annealing (RTA) has been investigated by using photoluminescence (PL), Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS), An increase
