Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts

ChemPhysChem, EarlyView.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic

Transfer reactions for nuclear astrophysics

EPJ Web of Conferences, 2018
Direct measurements of cross sections at stellar energies are very challenging - if at all possible. This is essentially due to the very low cross-sections of the reactions of interest (especially when it involves charged particles), and/or to the ...

Short Wavelength Limit of the Dynamic Matsubara Local Field Correction

Contributions to Plasma Physics, EarlyView.
ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{

Constraining properties of neutron stars with heavy-ion reactions in terrestrial laboratories

, 2007
Heavy-ion reactions provide a unique means to investigate the equation of state (EOS) of neutron-rich nuclear matter, especially the density dependence of the nuclear symmetry energy $E_{sym}(\rho)$.

Modelling Thomson Scattering in a Hydrogen Plasma at Stellar Interior Conditions Using the Hypernetted‐Chain Approach

Contributions to Plasma Physics, EarlyView.
ABSTRACT Under the extreme conditions found in small stars, where electron degeneracy and Coulomb coupling are significant, accurate modeling of Thomson scattering is crucial for determining opacity, a primary quantity for stellar energy transport.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

Contributions to Plasma Physics, EarlyView.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Electron Density Structure Measurements With Scattered Intense Laser Beam

Contributions to Plasma Physics, EarlyView.
ABSTRACT Short‐pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting from laser‐plasma interactions, the diagnostics to measure velocity distribution functions at the interaction region of the laser and plasma are limited.
