From wave function to crystal morphology: application to urea and alpha-glycine [PDF]

open access: yes, 1991
In this paper the relation between the molecular electron density distribution and the crystal growth morphology is investigated. Accurate charge densities derived from ab initio quantum chemical calculations were partitioned into multipole moments, to ...

Formation Thermodynamics of Carbamazepine with Benzamide, Para-Hydroxybenzamide and Isonicotinamide Cocrystals: Experimental and Theoretical Study

open access: yesPharmaceutics, 2022
Formation thermodynamic parameters for three cocrystals of carbamazepine (CBZ) with structurally related coformers (benzamide (BZA), para-hydroxybenzamide (4-OH-BZA) and isonicotinamide (INAM)) were determined by experimental (cocrystal solubility and ...

Cooling by conversion of para to ortho-hydrogen [PDF]

open access: yes, 1983
The cooling capacity of a solid hydrogen cooling system is significantly increased by exposing vapor created during evaporation of a solid hydrogen mass to a catalyst and thereby accelerating the endothermic para-to-ortho transition of the vapor to ...

Changes in the thermal characteristics of fullerenes in a nitrogen atmosphere [PDF]

open access: yesEPJ Web of Conferences
In order to study the thermal stability of Cn fullerenes (n = 28, 32, 44, 50, 56, 60, 70, 84, 90, 94) in a nitrogen environment during the transition from the condensed phase to the gas phase, the method of thermodynamic modeling is used.

New Zeolitic Imidazolate Framework‐Derived N‐Doped Carbon LiCl Composites for Sorption Thermal Batteries Utilizing Solar Energy

open access: yesCarbon Energy, EarlyView.
New hierarchical ZIF‐derived nitrogen‐doped carbons (ZDCs) impregnated with LiCl are promising materials for sorption thermal batteries utilizing solar energy. This study examines the structural properties of ZDCs, the effect of LiCl loading, the enhancement of hydrothermal stability by nanoporous carbon, and the water adsorption properties of a series
