Mesoporous zinc oxide microparticles were synthesized by the sol‐gel method, followed by hydrothermal treatment at three different temperatures (100°C, 120°C, and 140°C), confirming that the method is fast, simple, reproducible, and ecological. To carry out the synthesis of the samples, zinc acetate was used as a precursor and sodium hydroxide as a ...

Revisiting a place‐based policy: Transformations in Northeast Brazil
Abstract Despite being the second most populated region in Brazil, the Northeast has persistently accounted for a small share of national income. A well‐known attempt to develop the region was made in 1959 with the creation of SUDENE, a big push type of place‐based policy resulting in an intensification of industrial investments.

Ultrafast reaction‐sintering of grain size‐controlled titanium niobate from TiO2 and Nb2O5
Herein we present a fast‐firing approach to the solid‐state synthesis, yielding TiNb2O7 phase in less than 2 min, starting from tape‐cast titania (d50 = 0.26 μm) and niobia (d50 = 0.967 μm) green compacts. Besides significantly reducing processing time, fast‐firing enabled the hindering of grain growth, producing a material with grain size ∼0.5 μm ...
