Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Africa Regional Unification

African Journal of Political Science
Adebayo Adedeji and Prebisch are revered as generational thinkers and exemplars of regional economic integration in Africa and Latin America. Both have addressed unequal wealth distribution and unfavourable conditions that lead to underdevelopment. They

Sixty Years Later: Africa’s Stalled Decolonization

Vestnik RUDN. International Relations, 2020
The year 1960 marked the moment when the number of nominally independent African countries on the continent rose from nine to twenty-six and is a symbolic indicator of when Africa began to emerge from the days of European colonization.

Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

Advanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Atualidade do pensamento social brasileiro

Sociedade e Estado, 2011
Várias questões atualmente colocadas no âmbito das ciências humanas para o entendimento da sociedade foram, de vários modos, objeto da reflexão dos autores brasileiros ao longo dos anos: a problemática da emancipação, do direito à diferença, dos limites ...

Islam, Authoritarianism, and Underdevelopment

American Journal of Islam and Society, 2023
In 2019 Professor Ahmet Kuru published his acclaimed Islam, Authoritarianism, and Underdevelopment: A Global and Historical Comparison. I say ‘acclaimed’ not as an endorsement but merely to point to accolades it received, such as the jointly awarded and

Donor‐Engineered Chiral Indium–Salen Complexes for Tunable Circularly Polarized Luminescence

Advanced Functional Materials, EarlyView.
Chiral indium–salen complexes bearing electronically and structurally diverse donor substituents are presented as modular main‐group luminophores exhibiting tunable blue‐to‐green circularly polarized luminescence. Donor engineering systematically controls frontier‐orbital distribution, intraligand charge transfer, and excited‐state relaxation ...

Modal Analysis of Light Propagation, Polarization and Diffraction by Cholesteric Liquid Crystal Layers

Advanced Functional Materials, EarlyView.
The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.

Les politiques agricoles face au paradigme du sous-peuplement en République du Congo

Espace populations sociétés, 2019
Successive outbreaks of food prices on world markets have weakened food-importation dependent countries to feed their populations. This is the case of the Republic of the Congo, an oil rentier state that has appealed to foreign agricultural investors to ...

Enhanced Ferroelectric Phase Formation via Local Structure Modification in the Pre‐Crystalline State of Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Hafnium zirconium oxide thin films are grown using plasma‐enhanced atomic layer deposition with the addition of an atomic layer annealing (ALA) step. ALA leads to a change in the short‐range structure of the deposit and encourages formation of the ferroelectric Pca21 phase. The result is wake‐up‐free performance with films exposed to ALA.
