Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2

Small, EarlyView.
Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...

A nemzetgazdasági és a regionális konvergencia mérése az EU-ban [PDF]

, 2014
Az elmúlt két évtizedben valamennyi új kelet-közép-európai tagállam egy főre jutó GDP-je közelített az EU-átlaghoz, miközben a nemzetgazdaságokon belül a megyék, régiók közötti jövedelmi különbségek minden országban nőttek – a fejlettebb megyék ...

Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

The Chemical Record, EarlyView.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Regio- and Diastereoselective C-C Silylation of Cyclopropyl Acetates Harnessing Fluorinated Poly(pyridyl)Borate Rhodium Catalysts. [PDF]

Chemistry
Fluorinated poly(pyridyl)borates have been utilized to stabilize rhodium‐diene complexes and as supporting ligands in rhodium‐catalyzed redox‐neutral C–C silylation of cyclopropyl acetates, producing silicon‐containing heterocyclic products, dioxasilolanes.

Phenology of migrating game birds in Italy based on citizen science data

Wildlife Biology, EarlyView.
Studying the timing of the seasonal movements of migratory birds, known as migration phenology, is crucial for managing and conserving migratory bird populations. This is particularly important for migratory game bird populations in Europe because, according to the EU, migratory birds should not be hunted during their breeding season or during return ...

Hospitaller Revenues, Bourbon Regalism: The Financial Administration of the Grand Priory of Castile and León under an American Parvenu

History, EarlyView.
Abstract After the vicissitudes of the War of the Spanish Succession (1701–14), the consolidation of the Bourbon Monarchy in early eighteenth‐century Spain allowed Philip V's ministry to implement the so‐called Nueva Planta in his various kingdoms and lordships of the Crown of Aragon, but also in Castile.

WHAT DOES IT TAKE TO ‘ACCEPT’ URBAN SHRINKAGE? A Comparative Analysis of Discursive Pathways to Policy and Action on Shrinking Cities in the Netherlands and Finland

International Journal of Urban and Regional Research, EarlyView.
Abstract Shrinking cities are increasingly drawing global attention, but urban shrinkage is seldom considered as an enduring structural condition necessitating a move beyond growth‐centric strategies. The focus often remains on mitigating symptoms rather than embracing the broader implications of long‐term decline. Understanding of what drives decision‐

Integrációs kísérlet Délkelet-Ázsiában = Building an Integration in South East Asia. The ASEAN+3 Cooperation [PDF]

, 2011
A világban tapasztalt regionalizációs és integrációs folyamatok közül a viharosan fejlődő délkelet-ázsiai térség sem képez kivételt. Az 1967-ben alapított ASEAN egészen a nyolcvanas évekig csak egy volt a világban látható számos integrációs kezdeményezés
