Isotope effects on transport characteristics of edge and core plasmas heated by neutral beam injection (NBI) in an inward shifted configuration at the Large Helical Device

Nuclear Fusion
Isotope effects have been investigated in Neutral Beam Injection (NBI) heated plasmas on the Large Helical Device with similar operational parameters between Hydrogen (H) and Deuterium (D) plasmas.

Understanding Decoherence of the Boron Vacancy Center in Hexagonal Boron Nitride

Advanced Functional Materials, EarlyView.
State‐of‐the‐art computations unravel the intricate decoherence dynamics of the boron vacancy center in hexagonal boron nitride across magnetic fields from 0 to 3 T. Five distinct regimes emerge, dominated by nuclear spin interactions, revealing optimal coherence times of 1–20 µs in the 180–350 mT range for isotopically pure samples.

Wet Photolithography From Hydrogen Abstraction of a Quasi‐Orthogonal Aggregation‐Induced Emitter

Advanced Science
A new aggregation‐induced emission (AIE) luminogen is obtained by dimerizing acridin‐9(10H)‐one (Ac), an aggregation‐caused quenching (ACQ) effect monomer via an N─N bond and forming 9H,9′H‐[10,10′‐biacridine]‐9,9′‐dione (DiAc) with D2d symmetry.

Evidence for very strong electron-phonon coupling in YBa_{2}Cu_{3}O_{6}

, 2007
From the observed oxygen-isotope shift of the mid-infrared two-magnon absorption peak of YBa$_{2}$Cu$_{3}$O$_{6}$, we evaluate the oxygen-isotope effect on the in-plane antiferromagnetic exchange energy $J$.

Selective and Precise Editing of Digital Polymers Through Parallel or Series Toehold‐Mediated Strand Displacement

Advanced Functional Materials, EarlyView.
A sequence‐encoded supramolecular construct containing two accessible toeholds is developed herein for enabling multiple editing operations. By introducing specific input strands, it is possible to selectively erase or rewrite digital content through parallel or series toehold‐mediated strand displacement (PTMSD or STMSD).

Isotope shifts of the 2$p_{3/2}$-2$p_{1/2}$ transition in B-like ions

, 2016
Isotope shifts of the 2$p_{3/2}$-2$p_{1/2}$ transition in B-like ions are evaluated for a wide range of the nuclear charge number: Z=8-92. The calculations of the relativistic nuclear recoil and nuclear size effects are performed using a large scale ...

The mechanism of oxygen isotope fractionation during N2O production by denitrification [PDF]

, 2015
The isotopic composition of soil-derived N2O can help differentiate between N2O production pathways and estimate the fraction of N2O reduced to N2. Until now, δ18O of N2O has been rarely used in the interpretation of N2O isotopic signatures because of ...

Dopant Deuteration Enables Long‐lived Room‐temperature Phosphorescence

Aggregate
Organic host–guest systems exhibiting room‐temperature phosphorescence (RTP) hold great promise for sensing, encryption, and bioimaging. However, achieving both long lifetimes and high efficiency remains challenging, as enhanced spin–orbit coupling (SOC)
