Yb2‐Tb Upconversion in a Hetero‐Trimetallic Molecular Lanthanide Complex

open access: yesAngewandte Chemie, EarlyView.
Lanthanides are at the forefront of photon upconversion in molecular systems; however, the chemical nature of the lanthanides makes site‐specific coordination chemistry difficult to achieve. Here, we employ kinetically stabile building blocks to achieve hetero‐trimetallic 4f complexes with complete site‐specific chemical control.

Dimorphic enantiostyly and its function for pollination by carpenter bees in a pollen‐rewarding Caribbean bloodwort

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Healthcare Resource Utilization and Cost After Temperature‐Controlled Radiofrequency Treatment of Nasal Airway Obstruction: A Real‐World Longitudinal Claims Analysis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Nasal airway obstruction (NAO) is prevalent with substantial health and quality of life burdens. Nasal valve collapse (NVC) is one structural cause of NAO. Temperature‐controlled radiofrequency (TCRF) nasal valve remodeling offers an alternative to invasive surgery.

Boosting the Nucleophilicity of the Diphenylphosphide Anion with Crown Ether Supported Heavy Alkali Metals to Facilitate Highly Efficient Catalytic Alkene Isomerisation

open access: yesAngewandte Chemie, EarlyView.
Here, we report a breakthrough study in catalytic alkene isomerisation using crown ether‐supported alkali metal phosphides in which the activity increases sequentially and significantly as Group One is descended with Cs(18‐crown‐6)PPh2 (1Cs) performing best.

Differences in cynomolgus macaque populations used for infectious disease research

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Cynomolgus macaques, a species of Old World primate native to southeastern and eastern Asia and the island of Mauritius, are one of the most important nonhuman primate models for infectious disease. Research into the population genetics of cynomolgus macaques has found significant differences between macaques native to different areas, particularly ...

Host‐Guest Doping Enables Room Temperature Phosphorescence from Triarylboranes

open access: yesAngewandte Chemie, EarlyView.
While pure triarylboranes show RTP in annealed PMMA films, they do not in crystalline form, contrary to our previous report. However, crystalline host‐guest triarylborane systems show persistent afterglow up to 8 s even at 1 ppb guest loading. Computations identify triplet‐triplet energy transfer as the mechanism governing this efficient RTP.
