Bi‐Directional Assembly of Boron Nitride µ‐Platelets by Micro‐Molding for Advanced Thermal Interface Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

Artificial Modulation of the Hydrogen Evolution Reaction Kinetics via Control of Grain Boundaries Density in Mo2C Through Laser Processing

open access: yesAdvanced Functional Materials, EarlyView.
A laser‐driven strategy enables precise microstructural modulation of Mo₂C, achieving nanoscale grain control (15.6 ± 5 nm) and an ultrahigh grain boundary density (130 µm−1). Moreover, high‐angle grain boundaries enhance active sites, facilitate electron transport, and optimize hydrogen adsorption kinetics, significantly reducing overpotential.

Direct Democracy at the Local Level in Poland

open access: yesПроблеми на постмодерността, 2013
Direct democracy was not known in Poland in the period before the World War II while in People’s Poland there were no proper conditions to implement it. The forms of direct democracy at the local level are village meetings, general meetings of people in ...

Trust the People? Populism, Trust, and Support for Direct Democracy

open access: yesPolitics and Governance
Populism is commonly understood as a response to frustrations with the functioning of modern democracy, while the use of direct democratic mechanisms has been hailed as a remedy for the ailing of representative democracies. Indeed, populism’s emphasis on

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States

open access: yesAdvanced Functional Materials, EarlyView.
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

Beyond the Veil of Ignorance: The Influence of Direct Democracy on the Shadow Economy [PDF]

open access: yes
In this paper we analyze the influence of direct democratic institutions on the size and development of the shadow economies. The framework developed predicts a negative relationship between the degree of direct democracy and the size of the shadow ...

5,11‐Di(thiophen‐2‐yl)Tetracene: A Novel Tetracene Derivative for Efficient Singlet Fission with Enhanced Physical and Chemical Stability in Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a new tetracene derivative, 5,11‐di(thiophen‐2‐yl)tetracene (2T‐Tc) is introduced, exhibiting enhanced physical and chemical stability, and retaining favorable singlet fission kinetics with near unity triplet pair yield in thin films.
