Development of a Simultaneous SANS/FTIR Measuring System [PDF]
Chemistry Letters, 2015 Abstract A novel method for the simultaneous measurement of small-angle neutron scattering and Fourier transform infrared spectroscopy (SANS/FTIR) has been developed. The method was realized by building a device consisting of a portable FTIR spectrometer and an optical system that allows both a neutron beam and an infrared beam to pass ...

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
