Negative thermal expansion property of Eu0.8Sr0·2MnO3-δ
We firstly synthesized the novel negative thermal expansion (NTE) material Eu0.8Sr0·2MnO3-δ with superior physical properties by solid state method. Apart from the NTE properties, the micro constitution and structure are also presented.

Understanding the role of guest ions in the control of thermal expansion of FeFe(CN)6
Understanding the role of guest species in framework materials is important to successfully achieve the control of thermal expansion. In this work, the thermal expansion of the Prussian blue analogue FeFe(CN)6 has been effectively tailored from negative,

Negative thermal expansion materials † [PDF]
The ZrW2O8 family of materials has been shown to exhibit the unusual property of negative thermal expansion over a wide temperature range. α-ZrW2O8 itself shows negative thermal expansion from 2 K to 1443 K with a coefficient of thermal expansion α1 of -9.1×10-6 K-1 between 2 and 300 K. This behaviour can be related to the unusual structure of these

Understanding the negative thermal expansion in planar graphite–metal composites [PDF]
The addition of graphitic fibers and flakes as fillers is commonly used to control the thermal expansion of metals. Sintered metal matrix composites with a planar distribution of graphite flakes show a low or negative thermal expansion coefficient ...

Kondo-Induced Giant Isotropic Negative Thermal Expansion
Negative thermal expansion is an unusual phenomenon appearing in only a handful of materials, but pursuit and mastery of the phenomenon holds great promise for applications across disciplines and industries. Here we report use of X-ray spectroscopy and diffraction to investigate the 4f-electronic properties in Y-doped SmS and employ the Kondo volume ...
