From Crystals to Disordered Crystals: A Hidden Order-Disorder Transition [PDF]
Sci. Rep. 5, 15378 (2015), 2015 We find an order-disorder transition from crystals to disordered crystals for static packings of frictionless spheres. While the geometric indicators are mostly blind to the transition, disordered crystals already exhibit properties apart from crystals.

Chirality-selected crystal growth and spin polarization over centimeters of transition metal disilicide crystals [PDF]
, 2022 We performed a chirality-controlled crystal growth of transition metal disilicide NbSi$_{2}$ and TaSi$_{2}$ by using a laser-diode-heated floating zone (LDFZ) method. The crystal chirality was evaluated in the crystals of centimeters in length by performing single crystal X-ray diffraction as well as probing a spin polarization originating from ...

Human versus robots in the discovery and crystallization of gigantic polyoxometalates [PDF]
, 2017 The discovery of new gigantic molecules formed by self-assembly and crystal growth is challenging as it combines two contingent events; first is the formation of a new molecule, and second its crystallization.

Crystallization kinetics of poly(lactic acid)-talc composites [PDF]
, 2011 The crystallization kinetics of Poly(lactic acid) / talc composites were determined over a range of 0 wt.% to 15 wt.% of talc. Talc was found to change the crystallization kinetics.

Confined Crystallization of Pigment Red 146 in Emulsion Droplets and Its Mechanism
Nanomaterials, 2019 In this work, the effect of confined space on crystallization processes of pigments was investigated by using C.I. Pigment Red 146 (PR 146) as a model compound. The colloidal system (i.e., emulsion droplets) was used as a nanoreactor to prepare nanoscale

Noble Metal-Free TiO2-Coated Carbon Nitride Layers for Enhanced Visible Light-Driven Photocatalysis
Nanomaterials, 2020 Composites of g-C3N4/TiO2 were one-step prepared using electron impact with dielectric barrier discharge (DBD) plasma as the electron source. Due to the low operation temperature, TiO2 by the plasma method shows higher specific surface area and smaller ...
