Thermoluminescence study of electron-irradiated LiZnBO3 phosphor for dosimetry application

Nuclear Engineering and Technology
This work investigates the structural and thermoluminescence (TL) properties of LiZnBO3 (LZB) phosphor irradiated with 6 MeV, 9 MeV, and 12 MeV electrons in the dose range of 0.5 Gy–8 Gy, focusing on its potential for medical radiation dosimetry.

Verbesserte Auflösung in der ESR‐Spektroskopie unter Verwendung von para‐Wasserstoff‐Matrizen

Angewandte Chemie, EarlyView.
Wir demonstrieren die vorteilhaften Eigenschaften von festen para‐Wasserstoff (p‐H2)‐Matrizen für die Elektronenspinresonanz (ESR) Spektroskopie, indem wir das 2,2,6,6‐Tetramethylpiperidinyloxyl (TEMPO)‐Radikal und ein in situ erzeugtes P‐zentriertes Monoradikal untersuchen. Die spektrale Auflösung des P‐zentrierten Radikals in p‐H2 ist im Vergleich zu

Ungesättigte Phosphor‐Elektrophile zur Untersuchung von Protein‐Tyrosin‐Phosphatasen

Angewandte Chemie, EarlyView.
Negativ geladene Aryl‐Ethynyl‐Phosphonamid‐ und Phosphonsäuren werden als reaktionsarme Elektrophile für peptidbasierte Aktivitätssonden eingeführt, die eine selektive, zielspezifische Profilierung von Protein‐Tyrosin‐Phosphatasen ermöglichen. Die Sonden zeigen keine Off‐Target‐Cystein‐Reaktivität und binden in der globalen Proteomanalyse nur an die ...

Hochdrucksynthese von Antimonnitrid Sb3N5 und Polynitrid Sb2N8 mit einfach gebundenen N810− Ketten

Angewandte Chemie, EarlyView.
Hochdrucksynthesen zwischen Antimon und molekularem Stickstoff in einer laserbeheizten Diamantstempelzelle führten zur Bildung von oC32‐Sb3N5 (51(1) GPa) und mP20‐Sb2(N8) (> 100 GPa). Beide Phasen wurden mittels Einkristall‐Röntgenmikrodiffraktion identifiziert und durch Berechnungen mittels Dichtefunktionaltheorie vollständig bestätigt.

Functional Interface Engineering Enables Selective Multicolor Upconversion in NaErF4@NaYF4 Core–Shell Nanocrystals

Advanced Physics Research, EarlyView.
A functional interface engineering strategy is proposed to tune upconversion of NaErF4@NaYF4 core–shell nanocrystals by adjusting the amount of CF3COONa in the precursor during the shell growth. It is able to introduce controllable lattice defects at the core–shell interface to manipulate energy migration paths and non‐radiative transition of Er3 ...

Excellent Color Purity and Luminescence Thermometry Performance in Germanate Tellurite Glass Doped with Eu³⁺ and Tb³⁺

Applied Sciences
Germanate tellurite glasses doped with Eu3+ and Tb3+ were synthesized by the conventional melt-quenching method. There is no indication of the energy transfer between dopant ions in this host, but the co-dopants exhibit excellent color purity of 100% for

The Application of Carbon Dots in Crops for Sustainable Agriculture

ChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

High Pressure Stabilizes the Elusive Hexacoordinated Carbon

ChemistryEurope, EarlyView.
The MCF6 species (M = Ca, Sr) is more stable than the bicomponent MF2…CF4 mixture in the solid‐state at high pressure (p > 400 GPa). The main building block is the [CF6]2− unit in which carbon is hexacoordinated. Unusually high coordination number for elements has been of great interest in chemistry.
