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.

Updating democracy studies: outline of a research program [PDF]

open access: yes, 2012
Technologies carry politics since they embed values. It is therefore surprising that mainstream political and legal theory have taken the issue so lightly.

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.

Highly Efficient 3D‐Printed PVDF‐Based Triboelectric Nanogenerators Featuring Polymorphic Perovskite Nanofillers

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.
