Negative Thermal Expansion in Open Perovskites near the Precipice of Structural Stability
(2018)
Negative thermal expansion (NTE) describes the anomalous propensity of materials to shrink when heated. Since its discovery, the NTE effect has been found in a wide variety of materials with an array of magnetic, electronic ...

Spin reorientation, magnetization reversal, and negative thermal expansion observed in RFe0.5Cr0.5O3 perovskites (R = Lu,Yb,Tm)
(American Physical Society, 2016-10)
Three members of the perovskite family RFe0.5Cr0.5O3 (R = Lu,Yb, and Tm) have been synthesized and characterized. A systematic study of the crystal and magnetic structures was performed by neutron powder diffraction combined ...
Large isotropic negative thermal expansion above a structural quantum phase transition
(2015-10-01)
Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of energy solutions. An always-contributing ...

Supramacromolecular organization of gold nanocrystals capped with amphiphilic hyperbranched polyethyleneimine
(Elsevier, 2013-05)
The supramolecular structural aspects of hetero-assemblies constituted of gold nanoparticles capped with amphiphilic unimolecular micelles were studied using synchrotron-based small angle X-ray scattering (SAXS). Experimental ...
Molecular explanation for the abnormal flux of material into a Hot Spot in Ester Monolayers
(American Chemical Society, 2017-06)
Langmuir monolayers of certain surfactants show a negative derivative of the surface pressure with respect to temperature. In these monolayers, a local temperature gradient leads to local yielding of the solid phase to a ...
Low (and negative) thermal expansion Al2TiO5 materials and Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4 composite materials. Processing, initial zircon proportion effect, and properties
(Elsevier, 2018-12)
Aluminum titanate (Al2TiO5) materials and aluminum titanate - mullite- zirconium titanate (Al2TiO5 - 3Al2O3.2SiO2 - ZrTiO4) composite materials were successfully processed from fine commercial powders and characterized. ...
