Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are... -
Probing the magnetic structure of transition metal pyrovanadate Fe2V2O7
We have synthesized and characterized a new member, namely Fe2V2O7 in the family of 3d transition metal pyrovanadate M2V2O7 (M =Mn, Fe, Co, Ni, Cu). M2V2O7 exist with a great... -

The Bragg edge transmission (BET) analysis is a technique exploiting the presence, position and shape of the edges which form in time of flight transmitted neutron beams. This... -
Probing Novel Phenomena in Sodium Bismuth Titanate
Sodium Bismuth Titanate, Na0.5Bi0.5TiO3 (NBT) is a mixed A-site perovskite. It is both of commercial interest, due to its usage in lead-free piezoelectric solid-solutions; and... -
The crystal structure of a Co(II) cubane single-molecule magnet
Single molecule magnetism is a low temperature phenomenon. Even though there have been thousands of papers published in the area, there are no structural data at all for any... -
Determination of the detection limits and quantitative analysis reliability o...
Neutron diffraction offers one of the most interesting and meaningful methods for non destructive quantitative determination of the phase composition of materials. However, it... -
Structural Studies of Li(ND3)n11BD4
On exposure to ammonia, Li(11)BD4 forms the ammoniate Li(11)BD4(ND3)n. Our recent experiment (RB820252) has shown that there are four distinct crystalline phases in the... -
Thermal evolution of the structures of Ba2Cu1-xO2-yCu2Se2 phases
We will probe the structural changes as a function of temperature associated with oxide ion disorder/mobility in the end members of a redox-active oxide chalcogenide system. -
Hydrogen production from ammonia using lithium imide: an isotope study
We have recently discovered that light metal amides and imides are excellent cattalysts for the decomposition of ammonia. We request 3 days on POLARIS to perform in situ neutron... -
In-situ Gravimetric Study of the Decomposition of Alkali Metal Amidoboranes
We request 3 days on HRPD with the IGAn apparatus, to perform in-situ neutron diffraction and thermogravimetric studies of the decomposition of deuterated alkaline amidoboranes.... -
