Adsorption evaluation of large-size HDEHP/SiO2-P adsorbent investigated by micro-PIXE analysis

Yuji Miyazaki、Ichiro Goto、S. Watanabe 等 7 位作者2019-01-01International Journal of PIXE

The Zr and Mo removal from HLLW is the current issue for repeated usage of the CMPO/SiO2-P-packed column. The adsorbability of the 2-mm-sized HDEHP/SiO2-P adsorbent, which was prepared by fabricating a SiO2 particle from the vibration cutting method and adapting a new polymerization method, was evaluated by the batch-…

Study of Seven-Bend Achromat Lattices with Interleaved Dispersion Bumps for HALS

Zhenghe Bai、Wei Li、Gangwen Liu 等 6 位作者2019-01-01JACOW

Previously, we proposed a multi-bend achromat (MBA) lattice concept, called the MBA with interleav-ed dispersion bumps, which was then used to design a 7BA lattice for the Hefei Advanced Light Source (HALS) storage ring. Recently, such a 7BA lattice was further designed and optimized for the HALS by changing the numbe…

Particle-mesh two-dimensional pattern reverse Monte Carlo analysis on filled-gels during uniaxial expansion

Katsumi Haita2019-01-01Soft Matter

A particle-mesh-based two-dimensional pattern reverse Monte Carlo (RMC) analysis method (PM-2DpRMC) is proposed for analyzing two-dimensional small-angle-scattering (2D-SAS) patterns. The results of analyzing such patterns in expanded gel networks filled with spherical nano-particles during uniaxial elongation are pro…

The potential of wood acetylation

Ferry Bongers、Stephen J. Uphill2019-01-01Research Repository (Delft University of Technology)

Wood, having the lowest embodied energy of any mainstream building material, is carbon neutral. As such, wood, our only naturally renewable construction resource, helps combat global warming by absorbing carbon from the atmosphere and storing it away for the life of the wood product. Not only is wood renewable, but it…
