A Platinum (II) Polyyne Oligomers Donor for Efficient Ternary Organic Solar Cells

open access: yesSolar RRL, EarlyView.
Platinum (II) polyyne oligomers P5 are used as a donor in a ternary organic solar cell. The average power conversion efficiency of 16% surpasses the international record for [Pt] (II) polyyne oligomers. PC71BM speeds up the rise time for electron transfer and slows down the recombination time.

Sum Peaks in a Total Reflection X‐Ray Fluorescence Spectrum of the Dry Residue of a Solution Sample Containing Ca

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT In this study, sum peaks related to the Ca Kα line (3.69 keV) were observed in total reflection X‐ray fluorescence spectra of dry residues of a solution sample containing a large amount of Ca, which were measured with a silicon drift detector. When dry residues containing 1 μg of Ca were measured, a peak that would be the sum peak of the Si Kα

New opportunities for grassland species in warming temperate winters

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperate winters are getting warmer, the length of the growing season is increasing and mid‐winter fluctuations of warm and freezing temperatures are more frequent. Although typically winter dormant, some herbaceous perennials can maintain or grow green leaves during ...

Local climate and genetic influence on intraspecific variation in torpor physiology of a cave‐roosting bat

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Many small endotherms employ torpor as a survival strategy to reduce energy expenditure during periods with low food availability and cold temperatures. The expression and physiology of torpor can vary substantially within species because of phenotypic plasticity and ...
