Centrosymmetric or Noncentrosymmetric?* BY RICHARD E. MARSH

In cases where diffraction data do not provide a clear choice between a centrosymmetric and a noncentrosymmetric space group, it is better to opt for the centrosymmetric description even though disorder may result. The disorder model implies that the crystal is a composite of two or more molecular structures that cannot be distinguished from one another. On the other hand, attempts to refine a ...

J. E. Shaw

1866 he used to get up every morning at six in order to get from Bath to his classes in Bristol punctually. In 1869 he went to Edinburgh to complete his course, and qualified there in 1872. He was House Physician at the Edinburgh Royal Infirmary, a Fellow of the Edinburgh Botanical Society and President of the Royal Medical Society of Edinburgh. In 1875 he returned to Clifton and two years late...

Performance of a Prototype MR-TOF-MS for the LEB of the Super-FRS

A multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) [1] will be an important part of the MATS/LaSpec beam-line at the Low-Energy-Branch (LEB) of the Super-FRS at FAIR. The MR-TOF-MS is a fast (∼ms), multi-purpose, non-scanning mass spectrometer with single-ion sensitivity and will be used as a broadband mass spectrometer, as isobar separator or for direct mass measurements of ver...

Description of the FRS domain

An FRS helps in the reservation of facilities (such as tutorial rooms, hotel rooms, lecture theaters) and specific equipment. Different organizations such as academic institutions, hotels, hospitals and companies, have different physical facilities and arrangements for their reservation. Most often, users (individuals or organizations) manage their own reservations with an FRS (e.g., add, delet...
