Palladacarboxamide Capping Reagents for Carbon Isotope Labeling and Pharmaceutical Diversification

Angewandte Chemie, EarlyView.
Herein, we present a method for carbon isotope labeling of arylamides via the coupling of air‐stable palladium carboxamide complexes and boronic ester/acids. A wide variety of functionalized boronic esters and acids have been coupled with simple palladium carboxamides complexes.

Real-Time Prediction of Operating Parameter of TBM during Tunneling

Applied Sciences, 2021
With the increasing use of the tunnel boring machine (TBM), attempts have been made to predict TBM operating parameters. Prediction of operating parameters is still an important step in the adaptability of the TBM for the future. In this study, we employ

Thermal Conductivity of Korean Compacted Bentonite Buffer Materials for a Nuclear Waste Repository

Energies, 2018
Engineered barrier system (EBS) has been proposed for the disposal of high-level waste (HLW). An EBS is composed of a disposal canister with spent fuel, a buffer material, backfill material, and a near field rock mass.

Cesium and strontium recovery from LiCl-KCl eutectic salt using electrolysis with liquid cathode

Nuclear Engineering and Technology, 2022
Deposition behaviors of Sr and Cs in various liquid cathodes, such as Zn, Bi, Cd, and Pb, were examined to evaluate their recovery from LiCl–KCl eutectic salt. Cations in the salt were deposited on the liquid cathode, exhibiting potential of −1.8 to −2.1

Numerical analysis of thermal process in the near field around vertical disposal of high-level radioactive waste

Journal of Rock Mechanics and Geotechnical Engineering, 2014
For deep geological disposal of high-level radioactive waste (HLW) in granite, the temperature on the HLW canisters is commonly designed to be lower than 100 °C. This criterion dictates the dimension of the repository.

Manufacturing method for meter-scale buffer material blocks

Yantu gongcheng xuebao, 2023
In the high-level radioactive waste (HLW) repository, the canisters are usually surrounded by buffer materials in the form of blocks. The manufacturing method for large-scale buffer blocks is regarded as a difficult problem to be solved in the in-situ ...
