Tellurophene‐Induced Triplet–Singlet Spin‐Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing

open access: yesAngewandte Chemie, EarlyView.
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

Exogenous application of molybdenum affects the expression of CBF14 and the development of frost tolerance in wheat. [PDF]

open access: yes, 2013
Wheat is able to cold acclimate in response to low temperatures and thereby increase its frost tolerance and the extent of this acclimation is greater in winter genotypes compared to spring genotypes.

Effect of Temperature and Humidity on Survival of Coptotermes formosanus and Reticulitermes flavipes (Isoptera: Rhinotermitidae)

open access: yesSociobiology, 2015
Two subterranean termite species were subjected to combinations of six temperatures (10°, 15°, 20°, 25°, 30°, or 35°C) and five relative humidities (RH) (55, 65, 75, 85, or 99%) to determine optimum conditions for survival.
