FeCu/MWCNT Nanocomposite with a Broad Microwave Absorption Band and Highly Reduced Radar Cross Section and Farfield

Advanced Electronic Materials, Volume 11, Issue 15, September 18, 2025.
FeCu bimetallic nanoparticles were synthesized using coprecipitation method. FeCu bimetallic nanoparticles decorated onto the MWCNT's sidewall with different weight ratios to produce novel FeCu/MWCNT nanocomposites. The results showed that a thin nanocomposite exhibited a broad absorption band with coverage of entire frequency bands.

Inconsistence of super-luminal Cern-Opera neutrino speed with observed SN1987A burst and neutrino mixing for any imaginary neutrino mass

, 2012
We tried to fit in any way the recent Opera-Cern claims of a neutrino super-luminal speed with observed Supernova SN1987A neutrino burst and all (or most) neutrino flavor oscillation. We considered three main frame-works: (1) A tachyon imaginary neutrino

Cosmological neutrino mass detection: The best probe of neutrino lifetime [PDF]

, 2007
Future cosmological data may be sensitive to the effects of a finite sum of neutrino masses even as small as ~0.06 eV, the lower limit guaranteed by neutrino oscillation experiments.

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Limits on the Low-energy Electron Antineutrino Flux from the Brightest Gamma-Ray Burst of All Time

The Astrophysical Journal
The electron antineutrino flux limits are presented for the brightest gamma-ray burst (GRB) of all time, GRB221009A, over a range of 1.8–200 MeV using the Kamioka Liquid Scintillator Antineutrino Detector. Using multiple time windows ranging from minutes

Status and Perspectives of 2ϵ, ϵβ⁺ and 2β⁺ Decays

Particles, 2021
This paper reviews the main experimental techniques and the most significant results in the searches for the 2ϵ, ϵβ+ and 2β+ decay modes. Efforts related to the study of these decay modes are important, since they can potentially offer complementary ...
