Effect of Polymer Removal on the Morphology and Phase of the Nanoparticles in All-Inorganic Heterostructures Synthesized via Two-Step Polymer Infiltration (open access)

Effect of Polymer Removal on the Morphology and Phase of the Nanoparticles in All-Inorganic Heterostructures Synthesized via Two-Step Polymer Infiltration

This article uses iron oxide/alumina heterostructures formed by two-step infiltration of polystyrene-block-polyvinyl pyridine block copolymer with iron and aluminum precursors from the solution and vapor-phases, respectively, to show that the phase and morphology of iron oxide nanoparticles dramatically depend on the approach used to remove the polymer. The article extends the boundaries of structure manipulations in multicomponent heterostructures synthesized using polymer infiltration synthesis and their properties.

Tuning the temperature range of superelastic Ni-Ti alloys for elastocaloric cooling via thermal processing (open access)

Tuning the temperature range of superelastic Ni-Ti alloys for elastocaloric cooling via thermal processing

Article describes how caloric cooling enlisting solid-state refrigerants is potentially a promising eco-friendly alternative to conventional cooling based on vapor compression. Here, the authors have explored tuning the operation temperature range of Ni50.8Ti49.2 for elastocaloric cooling. In particular, they have studied the effect of thermal treatments (a.k.a. aging) on the transformation temperature, superelasticity, and elastocaloric effects of Ni50.8Ti49.2 shape memory alloy tubes.
