Study of Nonleptonic Bq∗→DqV and PqD∗ Weak Decays

Advances in High Energy Physics, 2015
Motivated by the powerful capability of measurement for the b hadron decays at LHC and SuperKEKB/Belle-II, the nonleptonic B-∗→DD-∗, Dρ-, DK∗-, πD∗, and KD∗ decays are studied.

Simulation of Activation Experiments in an Irradiation Stand in the Context of Nuclear Decommissioning [PDF]

EPJ Web of Conferences
Monte Carlo simulations are a valuable tool to determine activated areas in nuclear power plants. This paper describes the simulation of an neutron irradiation stand containing 8 (α,n) sources and polyethylene shielding. The source spectrum of beryllium (

Micropleated Nanofibrous Filters for High‐Efficiency Submicron Aerosol Filtration: A Comparative Study with Chemical, Biological, Radiological, and Nuclear Gas Mask Filters

Advanced Engineering Materials, EarlyView.
This study presents micropleated filters manufactured by needleless electrospinning. Nanofibers are deposited onto uniaxially pre‐stretched substrates that contract upon release, forming densely packed micropleats. This architecture increases effective surface area without enlarging the filter size, achieving quality factors comparable to those of ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

A relativistic Glauber approach to polarization transfer in 4He(\vec{e},e'\vec{p})

, 2005
Polarization-transfer components for 4He(\vec{e},e'\vec{p})3H are computed within the relativistic multiple-scattering Glauber approximation (RMSGA). The RMSGA framework adopts relativistic single-particle wave functions and electron-nucleon couplings ...

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates

Advanced Engineering Materials, EarlyView.
An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,

Study of semileptonic B¯⁎→Pℓν¯ℓ decays

Nuclear Physics B, 2016
In anticipation of abundant B⁎ data samples at high-luminosity heavy-flavor experiments in the future, the tree-dominated semileptonic B¯u,d,s⁎→Pℓ−ν¯ℓ (P=D,Ds,π,K) decays are studied within the Standard Model. After a detailed calculation of the helicity

What Do Large Language Models Know About Materials?

Advanced Engineering Materials, EarlyView.
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

An Introduction to Nuclear Supersymmetry: a Unification Scheme for Nuclei

, 2004
The main ideas behind nuclear supersymmetry are presented, starting from the basic concepts of symmetry and the methods of group theory in physics. We propose new, more stringent experimental tests that probe the supersymmetry classification in nuclei ...
