Abstract: Delignified fibres from E. benthamii, E. nitens and E. smithii were treated with different NaOH concentrations (up to 30%, w/v) at two different temperatures (25 °C and 80 °C) to investigate the polymorphic and morphological variations in… read more here.

DOI: 10.1007/s10948-017-4439-0
Abstract: Ni0.4Co0.6Fe2O4 nanopowders were prepared via the co-precipitation route followed by annealing treatment. The structural and magnetic properties of the as-synthesized samples were determined by XRD, FT-IR, TG-DSC, and PPMS measurements, respectively. The XRD patterns indicated… read more here.

DOI: 10.1016/j.materresbull.2019.110531
Abstract: Abstract In this work, Yb3+, Tm3+ co-doped NaYF4 powders with several morphologies (spheres, micro-needles, and microrods) were successfully synthesized by varying the NaOH concentration from 0 to 2 M. The synthesis was carried out with pressure-assisted… read more here.
