Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

open access: yesFlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Northern bobwhites associated with native grass and shrubs have improved survival

open access: yesThe Journal of Wildlife Management, EarlyView.
Survival rates of adult northern bobwhites were improved by a combination of grazed native warm‐season grasses and well‐interspersed shrubs. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands conservation strategy to create habitat ...

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.

SPLITTING LOOPS AND NECKLACES: VARIANTS OF THE SQUARE PEG PROBLEM

open access: yesForum of Mathematics, Sigma, 2020
Toeplitz conjectured that any simple planar loop inscribes a square. Here we prove variants of Toeplitz’s square peg problem. We prove Hadwiger’s 1971 conjecture that any simple loop in $3$-space inscribes a parallelogram.

Understanding thermal conditions provides context for the influence of habitat characteristics on gamebird winter ecology

open access: yesWildlife Biology, EarlyView.
The fundamental niche of an organism is regulated partially by its ability to cope with a range of thermal environments, which can be directly influenced by management across spatial scales and seasons. However, despite winter weather being a major source of mortality for many species in northern latitudes, the impact of thermal conditions on wintering

Suppression of the superfluid Kelvin-Helmholtz instability due to massive vortex cores, friction and confinement

open access: yesSciPost Physics
We characterize the dynamical instability responsible for the breakdown of regular rows and necklaces of quantized vortices that appear at the interface between two superfluids in relative motion.
