On the Weil-étale Cohomology of S-Integers [PDF]

open access: yes, 2012
We generalize the Lichtenbaum's prototype of Weil-étale cohomology to S-integers and study its relation to the Tate sequences. In the final part, we present a more natural way to define Weil-étale cohomology for one-dimensional arithmetic schemes ...

Light‐Gated Control of Brownian Rotation by a Molecular Motor

open access: yesAngewandte Chemie, EarlyView.
A light‐driven molecular motor acts as a reversible steric gate for a nearby Brownian rotor. Photoisomerization switches the rotor between fast and hindered rotational regimes by modulating steric congestion around the rotational axis. The motor–rotor architecture enables a five‐order‐of‐magnitude difference in the rotational barrier, demonstrating ...

A quantitative Chevalley-Weil theorem for curves [PDF]

open access: yes, 2013
The classical Chevalley-Weil theorem asserts that for an étale covering  of projective varieties over a number field $K$, the discriminant of the field of definition of the fiber over a $K$-rational point is uniformly bounded.

3D Printed Ordered Porous Architectures of Functional Metal Tellurides for Ultra High Mass‐Loaded Ammonium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Aqueous ammonium‐ion batteries (AAIBs) are emerging as promising alternatives for next‐generation energy storage. To overcome the limited ion diffusion associated with ultrahigh mass‐loading electrodes, this work develops a 3D‐printed porous conductive electrode of metal‐telluride fabricated via selective laser melting technique.

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Raman Optical Activity as a Tool to Monitor Polynucleotide Conformation in Solutions

open access: yesChemistry – A European Journal, EarlyView.
Raman optical activity (ROA) studies of nucleic acids have been hindered by limited computational tools to link the spectra to the structure. The study shows that accurate density functional simulations are possible for model nucleotides, bringing more information about molecular geometry and dynamics in solutions.

Triptycene‐Based Tripodal Molecular Platforms: A Comparative Study of Photoswitchable Langmuir–Blodgett Films on Metallic and Nonmetallic Surfaces

open access: yesChemistry – A European Journal, EarlyView.
A modular triptycene‐based platform enables the preparation of Langmuir–Blodgett monolayers of structurally diverse molecular photoswitches on quartz and gold. Surface‐sensitive characterization and optical spectroscopy demonstrate that the intrinsic switching behavior is retained after surface immobilization. ABSTRACT Photoswitchable molecular systems
