Polymorphic Superparaelectric Engineering Boosting Energy Storage Capacity in BaTiO3‐Based Ceramics

open access: yesAdvanced Science, EarlyView.
Herein, Ca2+ incorporation promotes the coexistence of CaTiO3‐/BaTiO3‐derived paraferroelectric states, stabilizing cubic‐orthorhombic‐tetragonal polymorphic superparaelectric phases. This minimizes polarization energy barriers, facilitating full polarization saturation without compromising efficiency.

Unifying Composition and Process Design: A Heterogeneous Graph Neural Network for Discovering High‐Performance Cu Alloys

open access: yesAdvanced Science, EarlyView.
By overcoming the fixed‐path limitations of conventional machine learning, a heterogeneous graph neural network fundamentally reconstructs material data representation. Integrating variable processing sequences with intrinsic elemental features, this framework enables exploratory optimization across high‐dimensional spaces.

Engineering of Crystal and Domain Structures in Epitaxial Y:HfO2 Thin Films by YSZ Substrate Miscut

open access: yesAdvanced Science, EarlyView.
We investigate how YSZ substrate miscut influences crystal structure and domain formation in epitaxial Y‐doped HfO2 thin films. Using magnetron sputtering, high‐resolution X‐ray diffraction, atomic‐resolution scanning transmission electron microscopy, and first‐principles calculations, we systematically examine the characteristics of thickness‐ and ...

Commit to the Global South

Science, 2023
Vulnerabilities of the world’s least developed countries to health, economic, and environmental crises were recently in the spotlight at a United Nations (UN) conference in Qatar. In March, the Doha Programme of Action was announced as a call for the developed world to renew commitments to support low- and middle-income countries in overcoming major ...

Global North/South

2020
The Global North/South distinction is commonly invoked to capture a major cleavage in development or standard of living in the world between rich and poor countries. The North–South terminology follows earlier demarcations such as First and Third World, as well as the still-used “developed” and “developing” worlds. For the majority of the 19th and 20th

Global Souths

boundary 2, 2020
This essay explores alternative forms of political solidarity through a poiesis of longing that connects the Soviet aligned “South” in Kyrgyzstan and nonaligned “South” in decolonizing Algeria through a reading of two love stories by the Kyrgyz author and diplomat Chingiz Aitmatov, writing in 1958 on the periphery of the Soviet Union, and Algerian poet

The Global South

2017
The United Nations Conference on Housing and Sustainable Urban Development met in Quito, Ecuador, in October 2016 to launch a new global commitment to sustainable urban development. Habitat III, as the conference is called, resulted in the adoption of the New Urban Agenda, which prioritizes the relationship between urbanization and sustainable ...
