High-Pressure Routes to New Pyrochlores and Novel Magnetism
Inorganics, 2019 The pyrochlore structure (A2B2O7) has been an object of consistent study by materials scientists largely due to the stability of the cubic lattice with respect to a wide variety of chemical species on the A or B sites.

Superconducting properties of the pyrochlore oxide Cd2Re2O7
, 2001 We report the superconducting properties of the pyrochlore oxide Cd2Re2O7. The bulk superconducting transition temperature Tc is about 1.0 K, and the upper critical field Hc2 determined by the measurement of specific heat under magnetic fields is 0.29 T.

Advanced Science, EarlyView.This study addresses the critical issue of delamination between YSZ and GDC electrolytes in SOECs, which is caused by Thermal deformation disparity. A novel YSZ‐GDC composite interlayer, fabricated using a simple dip‐coating method, is introduced to solve this problem. This layer effectively suppresses delamination by mitigating thermal stress.

Advanced Science, EarlyView.Hierarchical Embedded Sphere Model combines DFT and interpretable machine learning to decode catalytic activity on TM‐doped MO2. It disentangles global electronic, active‐site, and local coordination effects, revealing two activation mechanisms: dopant‐driven (Rh@MO2) and coordination‐mediated (Fe@ZrO2).

Innovative Approach to Hydrogen Purification: A Review on the Role of Metal Hydrides
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Metal hydrides, renowned for their unique hydrogen bonding capabilities, have emerged as pivotal materials in the energy sector, particularly for hydrogen storage and purification applications. Their ability to store hydrogen reversibly under moderate conditions has positioned them at the forefront in hydrogen‐based energy systems. This review

Stuffed rare earth pyrochlore solid solutions [PDF]
Journal of Solid State Chemistry, 2006 Synthesis and crystal structures are described for the compounds Ln2(Ti2-xLnx)O7-x/2, where Ln = Tb, Dy, Ho, Er, Tm, Yb, Lu, and x ranges from 0 to 0.67. Rietveld refinements on X-ray powder diffraction data indicate that in Tb and Dy titanate pyrochlores, extra Ln3+ cations mix mainly on the Ti4+ site with little disorder on the original Ln3+ site ...

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

Quantum spin ices and topological phases from dipolar-octupolar doublets on the pyrochlore lattice
, 2014 We consider a class of d- and f-electron systems in which dipolar-octupolar Kramers doublets arise on the sites of the pyrochlore lattice. For such doublets, two components of the pseudospin transform like a magnetic dipole, while the other transforms ...
