Double Double to Double Perovskite Transformations in Quaternary Manganese Oxides [PDF]
Angewandte Chemie - International Edition, 2021 AbstractControl of cation ordering in ABX3 perovskites is important to structural, physical and chemical properties. Here we show that thermal transformations of AA′BB′O6 double double perovskites, where both A and B sites have 1:1 cation order, to (A0.5A′0.5)2BB′O6 double perovskites with fully disordered A/A′ cations can be achieved under pressure in

Double reflux: double trouble [PDF]
Gut, 1999 See article on page 598 The noxious agents responsible for injuring the oesophageal mucosa in patients with gastro-oesophageal reflux disease (GORD) may originate from two possible sources, the stomach and the duodenum. Hydrochloric acid and pepsin are the important gastric contents, whereas conjugated and unconjugated bile acids and trypsin are the ...

Double and double double perovskites in the RMnMnTaO6 series [PDF]
Journal of Solid State Chemistry, 2022 A new family of perovskites RMnMnTaO6 has been synthesised at high pressure for representative R = La, Nd, Sm, Eu, Gd, Y and Lu that span the whole rare earth series. The structure type changes from tetragonal P42/n double double perovskite (DDPv) type with columnar R3+/Mn2+ cation order (R = La, Nd, Sm) to monoclinic P21/n double perovskite (DPv) (

Blinding in Clinical Trials: Seeing the Big Picture
Medicina, 2021 Blinding mitigates several sources of bias which, if left unchecked, can quantitively affect study outcomes. Blinding remains under-utilized, particularly in non-pharmaceutical clinical trials, but is often highly feasible through simple measures ...
