Radioactivity Measurement of 85Kr by Using Anti-cosmic Ray Internal Gas Proportional Counter

open access: yesYuanzineng kexue jishu
85Kr is a noble gas radioactive nuclide with a half-life of 10.75 years, and it decays by emission of beta rays associated with weak gamma rays. Most of the 85Kr released into the atmosphere is artificially produced by neutron induced fission reactions ...

Do light nuclei display a universal γ-ray strength function?

open access: yesEPJ Web of Conferences, 2012
In this work we focus on properties in the quasi-continuum of light nuclei. Generally, both level density and γ-ray strength function (γ-SF) differ from nucleus to nucleus.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

New High‐Tc Charge‐Transfer Multiferroicity in the Quasi‐2D Antiferromagnet CrSbS3

open access: yesAdvanced Science, EarlyView.
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Near‐Unity Selectivity Inversion Between CO2 Electroreduction and H2 Evolution via Atomic Coordination Editing

open access: yesAdvanced Science, EarlyView.
Atomic coordination editing functions as an on/off switch that toggles single‐atom catalysts between CO2 electroreduction and hydrogen evolution. ABSTRACT Precise atomic coordination editing of single‐atom catalysts (SACs) provides an effective strategy to tune their electronic structures and catalytic selectivity. Yet, achieving near‐unity selectivity

Impact of Electrolyte Formulation on the Phase Behavior and Interphase Formation of Sb/Graphite Electrodes for K‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Electrolyte formulation is shown to govern both interphase chemistry and bulk phase evolution in Sb/graphite anodes for potassium‐ion batteries. A diglyme‐based localized high‐concentration electrolyte promotes a thin inorganic‐rich interphase, suppresses deep graphite potassiation, limits electrode swelling, and stabilizes amorphous KxSb formation ...

N-Closure and N-Interior in Neutrosophic Topological Spaces

open access: yesNeutrosophic Sets and Systems
Topology greatly benefits from the concept of δ-cloure. Its quiet nature to extended its proper-ties in other topological spaces. So, with the concept of quasi-coincidence Ganguly and Saha pioneered and extensively examined the notion of δ-closure ...

How Proton Incorporation Reshapes Lattice Dynamics In BaSnO3‐Type Proton Conductors

open access: yesAdvanced Science, EarlyView.
Yttrium‐doped BaSnO3 exhibits isotope‐dependent changes in its low‐energy vibrational density of states upon hydration. Comparison of dry, H2O‐, and D2O‐treated samples re‐veals mass‐dependent phonon renormalization linked to proton dynamics near oxygen va‐cancies, providing experimental insight into hydrogen‐coupled lattice excitations in proton ...

Regular Ordered Ternary Semigroups in Terms of Bipolar Fuzzy Ideals

open access: yesMathematics, 2019
Our main objective is to introduce the innovative concept of (α,ß)-bipolar fuzzy ideals and (α,ß)-bipolar fuzzy generalized bi-ideals in ordered ternary semigroups by using the idea of belongingness and quasi-coincidence of an ...

Donor Extended Blue TADF Dendrimer for High‐Performance Solution‐Processed OLEDs

open access: yesAdvanced Science, EarlyView.
A dendronized MR‐TADF emitter, DOBNA‐SpAc‐DCz, was designed to improve solubility, hole transport, and exciton dynamics for solution‐processed OLEDs. Incorporation of ter(tert‐butylcarbazole) dendrons decreases ΔEST and accelerates RISC, yielding short delayed lifetimes (∼2 µs).
