Designing Nonprofit Success: A Systematic Review of Board Design Choices and Organizational Performance

open access: yesNonprofit Management and Leadership, EarlyView.
ABSTRACT I synthesize 78 studies from leading nonprofit and public administration journals to explain why research on board design choices, board effectiveness, and organizational performance yields inconsistent findings. The analysis reveals that empirical contradictions stem primarily from theoretical misalignment and measurement diversity rather ...

Impact of polymer aging on main‐chain poly(fullerene)s with halide chain‐ends for inverted perovskite solar cells

open access: yesPolymer International, EarlyView.
Subtle variations in halogen chemistry significantly affect the aging behavior of polymeric electron transport layers in inverted perovskite solar cells, underscoring the importance of precise chemical design for enhancing long‐term stability. Abstract As perovskite solar cells (PSCs) advance toward commercialization, the need for stable and easily ...

Main‐chain polyfullerenes: Taking fullerene to the next dimension

open access: yesPolymer International, EarlyView.
This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.

Exploring eco‐evolutionary and temporal patterns of arbuscular mycorrhizal fungal communities colonizing Sorghum bicolor across sites of contrasting land use history and climate

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Sorghum bicolor is a globally important cereal crop with annual yields exceeding 50 million tons across more than 100 countries and can be grown on marginal lands where conventional agriculture is limited. We examined how eight genetically diverse sorghum genotypes shaped arbuscular mycorrhizal fungal (AMF) community assembly across two contrasting ...

Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.
