The temperature and chronology of heavy-element synthesis in low-mass stars [PDF]

, 2015
Roughly half of the heavy elements (atomic mass greater than that of iron) are believed to be synthesized in the late evolutionary stages of stars with masses between 0.8 and 8 solar masses. Deep inside the star, nuclei (mainly iron) capture neutrons and

Selective Benzene Capture by Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Advanced Functional Materials, EarlyView.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

Rotating proto-neutron stars: spin evolution, maximum mass and I-Love-Q relations

, 2014
Shortly after its birth in a gravitational collapse, a proto-neutron star enters in a phase of quasi-stationary evolution characterized by large gradients of the thermodynamical variables and intense neutrino emission.

Intensity of the neutron component of cosmic rays and air humidity

Solar-Terrestrial Physics
Neutron monitor data is currently corrected only for the barometric effect. We cannot, however, exclude that changes in air humidity affect the intensity of the cosmic-ray neutron component recorded by neutron monitors.

Commercial Sodium‐Ion Batteries: Understanding Mechanism and Function Using In Operando Neutron Diffraction and X‐Ray Tomography Studies

Advanced Functional Materials, EarlyView.
In operando neutron diffraction reveals the real‐time structural evolution of O3‐type NaxNi1/3Mn1/3Fe1/3O2 in commercial sodium‐ion batteries that is coupled with electrochemical and tomography data. The study establishes a direct link between current‐dependent phase transitions, lattice kinetics, and electrochemical behavior, offering mechanistic ...

Neutron stars velocities and magnetic fields

EPJ Web of Conferences, 2018
We study a model that explain neutron stars velocities due to the anisotropic emission of neutrinos. Strong magnetic fields present in neutron stars are the source of the anisotropy in the system.

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...
