Advanced Materials, EarlyView.Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Facts and Myths of Regional Development
Studia Regionalne i Lokalne, 2010 The paper critically discusses several widespread views about regional development and how it can be stimulated by regional policy. It is argued that in the current development paradigm it is neither possible nor expedient to achieve regional convergence,

Regioni italiane verso regioni europee: i fattori della mancata convergenza
Moneta e CreditoI sistemi economici regionali europei sono realtà economiche e sociali poco omogenee. Le regioni italiane sono tra le regioni europee quelle che hanno sofferto di più le politiche economiche sottese all’introduzione dell’euro in termini di investimenti,

Regional growth and local convergence: Evidence for Portugal [PDF]
It is widely known that regional disparities do not lead to economic growth. By this, it is meant that convergence among regions might be responsible for a propensity to national growth.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr
Advanced Materials, EarlyView.Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Convergence and divergence in living standards among regions of the enlarged European Union (1992-2006) [PDF]
This paper examines regional convergence in living standards among 264 EU27 regions during1992-2006. The main contribution is the exploratory analysis, which inspects various aspects of regional dynamics such as convergence and divergence, polarization ...

Regional income convergence in Portugal (1991-2012) [PDF]
, 2012 Our research aims to address the problem of inequality in income distribution from a different perspective than the usual. We intend to verify if geography influences the pattern of inequality, that is, if the standard of living varies from

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers
Advanced Materials, EarlyView.Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Regional Heterogenity and Conditional Convergence [PDF]
This paper stresses the importance of accounting for regional heterogenity in the dynamic analysis of regional economic disparities. Studies of regional growth invariably presume regions are homogenous in that their socio-demographic composition is ...

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...
