Ferroelectricity in Hf0.5Zr0.5O2 (HZO) originates from a polymorphic landscape where the metastable orthorhombic phase competes with monoclinic and tetragonal forms, making functional properties highly sensitive to structural instability. Recent strategies have exploited ionic-vacancy mechanisms, either through redox interactions with the environment or by employing ferroionic heterostructures, to
The new year in Sweden began with some record-breaking cold temperatures. Temperatures in the village of Kvikkjokk in the northern Swedish part of Lapland dropped to -43.6°C, the lowest recorded since records began in 1887.Yet for the majority of Swedish households, heating is not an issue. Those living in the multi-household apartment blocks that characterise Sweden’s towns and cities enjoy avera
Tudo o que comemos gera impactos ambientais: do uso do solo na lavoura, passando pelo transporte, processamento, consumo e descarte de embalagens e resíduos. Entender esse impacto ambiental da alimentação é complexo, mas já existem informações suficientes para orientar decisões mais bem informadas.
Ecosystems capture carbon dioxide (CO2) from the atmosphere and store it in vegetation and soil. They also release CO2 via plant and soil respiration or fires. If the CO2 uptake is larger than the release, an ecosystem acts as a net sink. This delicate balance can be easily disturbed by human actions such as cutting forests, clearing green areas for housing or roads, or by agricultural practices d
This chapter critically examines the pervasive belief that economic progress naturally leads to increased leisure time. While early 20th-century thinkers like John Maynard Keynes predicted a future of abundant free time driven by productivity gains, work hours in many high-income countries have stagnated or increased since the 1980s. The chapter argues that this paradox is not the result of indivi
This thesis studies reproducing kernels that are realized as pointwise quotients of two other kernels, including far-reaching generalizations of de Branges–Rovnyak spaces. In the first article, we study reproducing kernels arisingfrom the well-known multiplier criterion. They are intimately connected to certain operator inequalities, such asthe famous inequality of Shimorin in sub-Bergman spaces,
