Iterative Synthesis of Pentacene Derivatives with Continuous Boron–Oxygen Bonds

open access: yesAngewandte Chemie, EarlyView.
An iterative synthetic strategy enables the controlled introduction of continuous multiple B–O bonds at the zigzag edge of acenes. A simple two‐step cycle—ipso iodination and Suzuki cross‐coupling/condensation—efficiently constructs BO‐acenes ranging from naphthalene to pentacene.

Infrared and THz studies of polar phonons and improper magnetodielectric effect in multiferroic BFO3 ceramics

open access: yes, 2006
BFO3 ceramics were investigated by means of infrared reflectivity and time domain THz transmission spectroscopy at temperatures 20 - 950 K, and the magnetodielectric effect was studied at 10 - 300 K, with the magnetic field up to 9 T.

Markets Mitigate Land‐Use Competition From Energy Crops and Increase Farm Revenues

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Meeting the US Sustainable Aviation Fuel Grand Challenge target of 35 billion gal annually by 2050 will require an estimated 380 million–700 million dry tons of agricultural biomass feedstock. This study evaluates the implications of large‐scale biomass production for land use, crop production, and market outcomes under mature market ...

Covalent Network Formation Rate Controls Depletion‐Induced Supramolecular Assembly in Hybrid Double Network Hydrogels

open access: yesAngewandte Chemie, EarlyView.
Tuning the rate of covalent network formation in hybrid double network hydrogels regulates whether supramolecular filaments retain their low‐nm structures or depletion‐induced supramolecular assembly takes place forming bundles. This kinetic handle programs the mesoscale architecture and toughness of the hydrogels, establishing a link between ...

[Rezension zu:] Jonathan Wagner. A History of Migration from Germany to Canada, 1850-1939. Vancouver: University of British Columbia Press, 2006. 281 pp. Notes, bibliography, index. $29.95 (paper), ISBN 9780774812153 [PDF]

open access: yes, 2007
Jonathan Wagner has written a monograph on a migration movement that was in many ways a peripheral one. From a Canadian perspective, Germans accounted for a relatively minor share of immigrants, compared to former residents of the British Isles, of ...

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

open access: yesAdvanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...
