Application of Neutron Capture Reaction Rate from Kernel Ridge Regression Prediction in s-process Simulation

Yuanzineng kexue jishu, 2023
The origin of elements in the universe is a basic scientific problem. The slow neutron capture process (s-process) is believed to be responsible for the nucleosynthesis of about half of the elements heavier than iron.

Study of the Briquetting Process of Walnut Shells for Pyrolysis and Combustion

Applied Sciences, 2023
Walnut shells can be used as fuels in power plants directly or as biochars obtained by pyrolysis or torrefaction. They are an example of clean waste biomass which shows a low ash content and a high Net Calorific Value, making them excellent for energy ...

Assessment of Two Materials as Adsorbents for the Effective Removal and Further Pre-Concentration of Gallium from Aqueous Solutions: Mesoporous Carbon vs. Clinoptilolite

Separations, 2023
In this research, the adsorption of gallium onto natural zeolite (clinoptilolite) and two mesoporous-activated carbons were compared and evaluated. The clinoptilolite was treated with HCl (HCPL), while mesoporous-activated carbons (MCSG60A and MCO1) were

Sulfate radical anion-induced benzylic oxidation of N-(arylsulfonyl)benzylamines to N-arylsulfonylimines

Beilstein Journal of Organic Chemistry, 2023
A mild, operationally convenient, and practical method for the synthesis of synthetically useful N-arylsulfonylimines from N-(arylsulfonyl)benzylamines using K2S2O8 in the presence of pyridine as a base is reported herein. In addition, a “one-pot” tandem

s-Process Nucleosynthesis in Carbon Stars [PDF]

, 2002
We present the first detailed and homogeneous analysis of the s-element content in Galactic carbon stars of N-type. Abundances of Sr,Y, Zr (low-mass s-elements, or ls) and of Ba, La, Nd, Sm and Ce (high-mass s-elements, hs) are derived using the spectral

s-process Nuclear Reaction Rates

EPJ Web of Conferences, 2023
In stars the 13C(α, n)16O and 22Ne(α, n)25Mg reactions are the two main sources of neutrons for the so-called slow neutron capture process (s-process), which is one of the main mechanisms for the stellar synthesis of heavy elements. About 13C(α, n)16O, in despite of many efforts in measuring its cross section at the lower energies, only high ...

MONTAGE: AGB nucleosynthesis with full s-process calculations [PDF]

, 2009
We present MONTAGE, a post-processing nucleosynthesis code that combines a traditional network for isotopes lighter than calcium with a rapid algorithm for calculating the s-process nucleosynthesis of the heavier isotopes.
