Janus‐Type Photophysics of Rotational Isomers in a Diphenylanthracene Dimer

Angewandte Chemie International Edition, Accepted Article.
Organic molecular dimers serve as valuable model systems for manipulating and exploring interchromophore interactions. However, the structural flexibility introduced by linker or chromophore rotation gives rise to conformational isomers with distinct atomic arrangements, complicating the interpretation of photophysical processes.

Biodegradable Polyesteramide Films for Pervaporative Dehydration of Isopropanol–Water

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Polyesteramides are biodegradable polymers possessing good mechanical properties with potential applicability in membrane separations. In this work, polymer films from ε‐caprolactam and ε‐caprolactone‐based polyesteramides were prepared at a ratio of monomer units set so that the resulting copolymer had a low crystalline phase content.

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

The Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Human interparietal bones: Examination of existing classification schemes and development of a graphic library depicting variations

The Anatomical Record, EarlyView.
Examples from the graphic library depicting morphologies of interparietal bones, ossicles at lambda, mendosal sutures, and intrasutural ossicles. Abstract Due to its complex ossification during development, the superior region of the human occipital bone is a frequent site of supernumerary bones known as interparietal bones.
