Gas-phase Ortho-to-para Ratio of Formaldehyde Formed at Low Temperatures in Laboratory Ices

open access: yesThe Astrophysical Journal Letters, 2023
The ortho-to-para ratio (OPR) of formaldehyde (H _2 CO) has been used as a probe to estimate the formation temperature of molecules in interstellar, circumstellar, and cometary environments, relying on the assumption that nuclear spin conversion is ...

Influence of dewetting on the crystallization behavior of CuCl₂ in the presence of BSA during evaporation in a Petri dish

open access: yesHeliyon, 2019
The overall structure of dihydrate cupric chloride (CuCl2 * 2H2O) crystallization patterns in the presence of bovine serum albumin (BSA) in a Petri dish is influenced by dewetting. The dewetting behavior, which can be either before or after initial CuCl2

Critical temperature, surface tension and vapor density estimations of methanol using the scaled model

open access: yesHeliyon, 2019
In the present work, we applied scaled model to calculate surface tension, vapor densities and the critical temperatures of four different models of methanol: namely, H1, J1, J2 and L1 models.
