Tension in Chemistry and Its Contents
نویسنده
چکیده
This article makes a case for a positive role of tension in the creative process in chemistry. I begin with an argument that there is an inherent tension in what makes molecules interesting--their positioning along various polar axes. One of these, the age-old differentiation between useful (to society and for personal profit) commercialization and pure understanding of molecules and their reactions is characteristic. The question of whether there are any bad molecules then leads me to ethical concerns in chemistry, and a particular working out of these in interactions of chemists in the Middle East. An analysis is made of the special tensions involved in publishing, especially in citation ethics; chemists publish a lot, so this is situation ethics worked out on a daily basis. I then find in the literature of psychology good evidence for the positive value of moderate stress in stimulating creativity. It is obvious that too much tension leads to distress, and there are some institutional aspects of chemistry that do not come out well here. But all in all, the dynamic middle is alive, and it leads to good new science.

Density and Temperature Dependencies of Liquid Surface Tension
In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2 versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...
متن کاملA New Surface Tension Model for Prediction of Interaction Energy between Components and Activity Coefficients in Binary Systems
In this work, we develop a correlative model based on the surface tension data in order to calculate thermodynamic parameters, such as interaction energy between components (Uij), activity coefficients and etc. In the new approach, by using Li et al. (LWW) model, a three-parameter surface tension equation is derived for liquid mixtures. The surface tension data of 54 aqueous and 73 non-aqueous ...
متن کاملSurface Tension Prediction of n-Alkanes by a Modified Peng-Robinson Equation of State Using the Density Functional Theory
Through this study, the ability of a modified Peng-Robinson (MPR) equation of state in predicting the surface tension of n-alkanes based on the density functional theory approach was investigated and compared with other studies. The interfacial layer thickness and the density profile were calculated simultaneously at different temperatures from triple point to near critical point using the modi...
متن کاملSynthesis of Zinc-Sulfate Nano Particles and Detection of Their Induction Time, Nucleation Rate and Interfacial Tension
The production of zinc sulfate is important both medically and agriculturally. If zinc sulfate is produced without agglomeration at the nanoscale, its absorption in the body is more and faster. In this research, the induction time parameter is assessed for nucleation of zinc sulfate nanoparticles at room temperature and various supersaturations using acetone (as anti-solve...
متن کاملThe study of particle size distribution of calcium carbonate and its effects on some soil properties in khuzestan province
ABSTRACT-This experiment was carried out to study particle size distribution (PSD) of carbonates in soils and its effect on some calcareous soil properties in Khuzestan Province, Iran. Soil samples (n=72) were collected from different regions. To evaluate the effect of carbonates on water contents at pressure head of -1500kpa and PSD of soil samples, these properties were determined before and ...
