Do athermal amorphous solids exist?.

Physical review. E, Statistical, nonlinear, and soft matter physics

Hentschel HG, Karmakar S, Lerner E, Procaccia I.
PMID: 21797296
Phys Rev E Stat Nonlin Soft Matter Phys. 2011 Jun;83(6):061101. doi: 10.1103/PhysRevE.83.061101. Epub 2011 Jun 02.

We study the elastic theory of amorphous solids made of particles with finite range interactions in the thermodynamic limit. For the elastic theory to exist, one requires all the elastic coefficients, linear and nonlinear, to attain a finite thermodynamic...

PMID: 25146359
Chemistry. 2014 Sep 22;20(39):12399-404. doi: 10.1002/chem.201403150. Epub 2014 Aug 21.

Reaction of a linear bi-chelating N-donor achiral ligand with Zn(II) afforded a homochiral cationic framework with six-fold one-dimensional helical chains. The compound showed selective anion exchange behavior with interesting anion-responsive tunable bulk-phase homochirality. The cationic framework also presented anion-driven...
