Adaptive Compound Eye Imaging Device Based on Electrowetting Liquid Aperture with Adjustable Shape

open access: yesAdvanced Intelligent Systems, EarlyView.
Artificial compound eye technology enables imaging with a large field of view. However, the lack of adjustability limits its applications. An adaptive compound eye imaging device based on electrowetting liquid aperture with adjustable shape is proposed to achieve both large field‐of‐view imaging and adaptive imaging, including light intensity ...

Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

The unique morphological basis and repeated evolutionary origins of personate flowers in Penstemon

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Adaptive radiation in ecologically and morphologically diverse plant lineages presents an opportunity to investigate the rapid evolution of novel floral traits. While some types of floral traits, such as flower color, are well characterized, other types of complex morphologies remain understudied.

An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations

open access: yesAngewandte Chemie, EarlyView.
This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis

open access: yesAsian Journal of Organic Chemistry, EarlyView.
This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.
