Axion-like particles at CEvNS experiments

, 2019
In this talk, I will show the discovery prospects of Axion-like particle (ALP) at CE𝜈NS experiments. We consider the ALPs that couples to the standard model through the \(a \gamma \gamma\) interaction. The CE𝜈NS experiments, utilizing reactors and high-intensity proton beam at stopped pion experiments, produce a large number of photons that will be ...

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

The Influence of Unparticle and Axion like particle in Bhabha scattering

Communications in Physics
The effect of the unparticle and axion-like particle (ALP) at Bhabha scattering is analyzed. We evaluate the total cross-section with the propagators of gauge boson \(\gamma, Z\), unparticle (scalar and vector unparticle), and ALP which depends on the ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

Advanced Functional Materials, EarlyView.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Axion-like particles and e-ASTROGAM

, 2017
e-ASTROGAM is a space mission with unprecedented sensitivity to photons in the MeV range, proposed within the ESA M5 call. In this note we describe some measurements sensitive to axion-like particles, for which performance in the MeV/GeV range is of primary importance, and e-ASTROGAM could be the key for discovery. Keywords: Axions. ALPs.

Record Energy Storage Performance Metrics in Ferroelectric Hafnia‐Based Films through Heterostructure Design

Advanced Functional Materials, EarlyView.
Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

Axion Searches at the CERN SPS: From Their Dawn to Current Prospects

Condensed Matter
This mini-review traces the evolution of axion searches at the CERN Super Proton Synchrotron (SPS), beginning with the early proposal by Guido Barbiellini in 1982 and culminating in the recent advances of the NA62 and NA64 experiments.

A Host‐Guest, Zeolite/Organocation Material With Isotropic Zero Thermal Expansion

Advanced Functional Materials, EarlyView.
The use of selected organic structure directing agents for the hydrothermal synthesis of targeted zeolites exhibiting negative thermal expansion provides a straightforward strategy to obtain a new class of host‐guest, nanostructured, crystalline zero thermal expansion materials made of light and abundant elements.
