Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

open access: yesAdvanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

Fiscal federalism in Germany: Stabilization and redistribution before and after unification [PDF]

open access: yes
We provide empirical estimates of the risk-sharing and redistributive properties of the German federal from 1970 until 2006, with special attention to the effects of German fiscal system base unification.

Nanoscale Spatial Tuning of Superconductivity in Cuprate Thin Films via Direct Laser Writing

open access: yesAdvanced Functional Materials, EarlyView.
Maskless direct laser writing enables local control of oxygen stoichiometry in epitaxial YBCO thin films under ambient conditions. Sub‐micrometer grayscale patterns with tunable optical response and superconducting transport properties are achieved.

Fiscal federalism and regional growth : evidence from the Russian Federation in the 1990s [PDF]

open access: yes
Subnational fiscal autonomy-the basis for fiscal federalism in modern federations-is meant to serve two roles. First, local control over revenue collection is meantto provide a check on the capacity of central authorities to tax arbitrarily local capital.

Tough and Skin‐Free Porous Polyelectrolyte Complex Hydrogels via Salt‐Induced Aqueous Phase Separation

open access: yesAdvanced Functional Materials, EarlyView.
Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

Anchors Away: How Fiscal Policy Can Undermine "Good" Monetary Policy [PDF]

open access: yes
Slow moving demographics are aging populations around the world and pushing many countries into an extended period of heightened fiscal stress. In some countries, taxes alone cannot or likely will not fully fund projected pension and health care ...

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...
