Journal of Nanomaterials, Volume 2022, Issue 1, 2022., 2022 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
Growth and Change, Volume 52, Issue 4, Page 2412-2436, December 2021., 2021 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
International Journal of Ceramic Engineering &Science, Volume 3, Issue 6, Page 272-278, November 2021., 2021 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 ...

Developmental Science, Volume 24, Issue 6, November 2021., 2021 Abstract Poverty and teenage pregnancy are common in low‐and‐middle‐income countries and can impede the development of healthy parent‐child relationships. This study aimed to test whether a home‐visiting intervention could improve early attachment relationships between adolescent mothers and their infants living in poverty in Brazil.
