Penta‐ and Hexacoordinated Copper(II) Complexes with Azido and 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole Ligands with Field‐Induced Slow Magnetic Relaxation

open access: yesChemistryOpen, EarlyView.
A field‐induced slow magnetic relaxation was observed in an ionic pentacoordinated Cu(II) complex with 4‐amino‐3,5‐di‐2‐pyridyl‐4H‐1,2,4‐triazole and azido ligands. The analysis of the relaxation behaviour supports the origin of the slow magnetic relaxation in intramolecular low‐energy vibration modes participating in the one‐phonon direct and two ...

Synthesis, Structure, and Properties of Polyhydroxybutyrate Derived from Azotobacter Vinelandii N‐15

open access: yesChemistryOpen, EarlyView.
The bacterium Azotobacter vinelandii N15 synthesizes polyhydroxybutyrate (PHB) from sugar production waste. The study reveals the molecular composition, crystallinity, and thermal behavior of the synthesized biopolymer. Mechanical tests demonstrated high tensile strength and relatively low elongation at break. These properties highlight PHB's potential

A Framework for Understanding and Evaluating Localization: The Case of HelpAge International

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Many transnational non‐governmental organizations (TNGOs) are reevaluating their organizational forms and norms as they pursue localization. Localization itself is a contested and multifaceted concept, however, complicating the design, implementation, and evaluation of localization efforts.

The dovish turnaround: Germany's social benefit reform and job findings

open access: yesJournal of Policy Analysis and Management, EarlyView.
Abstract On the labor markets, recent decades were characterized by structural supply‐side reforms in many countries. Following its hawkish reforms from the 2000s, Germany has recently made a dovish turnaround. Conditions in basic income support for unemployed became more generous, combined with a focus on qualification and development.
