Synthesis and characterisation of new permethylpentalene (Pn*) zirconium bis(amido) Pn*Zr cyclopentadienyl mono(amido) complexes their reactivity with carbon dioxide.
Composite membranes were obtained by modification of heterogeneous polymer cation and anion-exchange membranes with nanoparticles of zirconium hydrophosphate and hydrated zirconium dioxide, respectively. The ion-exchange materials were investigated with the methods of electron microscopy, potentiometry, voltammetry, and impedance spectroscopy. Single nanoparticles, which were precipitated in aq...
Natural and synthetic fibres and particles are being introduced into the workplace and environment daily. Comparative analyses of the induced signalling pathways are essential in order to understand the potential hazards of these particles. To identify the molecular characteristics of particles and fibres, we selected crocidolite and chrysotile asbestos as representatives for fibered dust and t...
Graphene materials have found applications in a wide range of devices over the past decade. In order to meet the demand for graphene materials, various synthesis methods are constantly being improved or invented. Ball-milling of graphite to obtain graphene materials is one of the many versatile methods to easily obtain bulk quantities. In this work, we show that the graphene materials produced ...
Here we report the successful room temperature synthesis of zirconium phosphate nanoparticles (ZPNP) using the P123 tri-co-block polymer for the first time. The samples were characterized by SEM, TEM, XRD, TPD, and BET and were employed for fixation of CO2 on aniline to produce pharmaceutically important acetanilide under mild reaction conditions (150 °C and 150 Psi CO2 pressure).
Integration of luminescent rare earth ions and iridescence into a zirconium oxide photonic material is attractive for the design of new optical devices. The free-standing chiral nematic mesoporous films of ZrO2:Eu(3+) are assembled by a hard-templating approach using nanocrystalline cellulose-templated silica. The ZrO2:Eu(3+) films show tunable optical properties. The chiral nematic structured ...
