Molecular Dioxygen‐Mediated Passivation of Electron Traps in n‐Type Organic Charge‐Transfer Complexes

Angewandte Chemie International Edition, EarlyView.
O2 enhances charge‐transfer in n‐type organic donor–acceptor charge‐transfer complexes (CTCs) via physisorption‐mediated trap passivation. By suppressing recombination and promoting long‐lived delocalized charge carriers, O2 improves electron transport and conductivity without doping.

Anomeric Amide Enabled Divergent Synthesis of Unsymmetrical Ureas, Carbamates, Thioesters, and Amides From Aldehydes

Angewandte Chemie International Edition, EarlyView.
An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...

Asset Price Shocks, Real Expenditures, and Financial Structure:A Multi-Country Analysis [PDF]

This paper examines the response of the economies of 11 EU countries, Japan, and the United States to shocks in housing and equity prices. The effects are assessed with a Structural Vector Auto Regressive (SVAR) model, and four key findings emerge. First,

Guiding and Manipulating Light Fields in Microstructured Liquid Crystals

Advanced Physics Research, EarlyView.
This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

The Effects of Tamarix on Species Diversity in Formicidae Along the Dolores River, Big Gypsum Valley, Colorado [PDF]

, 2013
Invasive plant species do great harm in desert riparian ecosystems. In the southwest, Tamarix has been responsible for much of this damage. Although its effects have been studied, little is known about the changes it causes in arthropod communities in ...

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,
