Negative thermal expansion (NTE) is an intriguing physical property of solids, which is a
consequence of a complex interplay among the lattice, phonons, and electrons …

Polymer composites offered broad engineered applications, however their diversity get
restricted owing to fluctuations in thermomechanical properties during heating or cooling …

Perovskite oxides AB O3 continue to be a major focus in materials science. Of particular
interest is the interplay between A and B cations as exemplified by intersite charge transfer …

Colossal negative thermal expansion (NTE) with a volume contraction of about 8%, the
largest value reported so far for NTE materials, was observed in an electron‐doped giant …

Negative thermal expansion (NTE) of BiNi 1− x Fe x O 3 is investigated. All x= 0.05, 0.075,
0.10, and 0.15 samples shows large NTE with the coefficient of linear thermal expansion …

Polymer matrix composites filled with giant negative thermal expansion (NTE) materials
were formed by injection moulding. Antiperovskite manganese nitrides, thermal expansion …

Negative thermal expansion (NTE) has been found in some magnetic functional materials
due to the magnetovolume effect (MVE), in which an order-to-disorder magnetic transition …

Negative thermal expansion (NTE) induced by simultaneous mechanisms, that is, charge
transfer and polar–nonpolar transitions, was observed for the first time in BiNi1–x Fe x O3 …

Perovskite PbCoO3 synthesized at 12 GPa was found to have an unusual charge
distribution of Pb2+ Pb4+ 3Co2+ 2Co3+ 2O12 with charge orderings in both the A and B …

Abstract Pb M O3 (M= 3 d transition metals) family shows systematic variations in charge
distribution and intriguing physical properties due to its delicate energy balance between Pb …
