The growth and perfection of phenanthrene single crystals

A large anisotropic plasticity of L-leucinium hydrogen maleate preserved at cryogenic temperatures

“…Mechanical properties of molecular solids can be interpreted in the same way as those of ionic, covalent or metallic compounds, i.e. considering dislocations and their role in plasticity , 1971Thomas et al, 1972;Narang et al, 1974;Finnie et al, 2001;Perumal et al, 2002;Ramos & Bahr, 2007;Eddleston & Jones, 2016;Jones, 2017;Zhong et al, 2018;Li et al, 2018;Olson et al, 2018). However, for molecular crystals an alternative, simplified approach has also shown its efficiency: mechanical properties can be correlated with the anisotropy of regular crystal structure and intermolecular contacts and interactions (Reddy et al, 2005(Reddy et al, , 2006Kiran et al, 2010;Ghosh et al, 2013;Banlusan et al, 2015;Krishna, Shi et al, 2015;Naumov et al, 2015;Panda et al, 2015;Thomas et al, 2017;Worthy et al, 2018;Gupta et al, 2018;Matveychuk et al, 2018;Saha et al, 2018).…”

Knoop hardness anisotropy in anthracene and phenanthrene single crystals

“…On indenting the (001) cleavage planes with the long axis of the Knoop indenter parallel to the [010] direction, slip lines are observed along this direction in the case of phenanthrene (Narang et al 1974), but not in the case of anthracene. This causes the hardness value to be lower in the case of phenanthrene than anthracene.…”

Growth and characterization of an adduct 4-aminobenzoic acid with nicotinic acid

“…7b suggests that the sample possesses good optical quality with lesser defects [11,12] and this parameter is of vital importance for nonlinear optical applications.…”
