Query: A study of HFO-1234ze (1,3,3,3-Tetrafluoropropene) as an eco-friendly
  replacement in RPC detectors   The operations of Resistive Plate Chambers in LHC experiments require F-based
gases for optimal performance. Recent regulations demand the use of
environmentally unfriendly F-based gases to be limited or banned.
  This report shows results of studies on performance of RPCs operated with a
potential eco-friendly gas candidate 1,3,3,3-Tetrafluoropropene, commercially
known as HFO-1234ze.
