Chemical Oscillators in Structured Media

open access: yes, 2011
Evolution is a characteristic feature of living systems, and many fundamental processes in life, including the cell cycle, take place in a periodic fashion. From a chemistry perspective, these repeating phenomena suggest the question of whether reactions

Comparative Study of Predicting the Molecular Diffusion Coefficient for Polar and Non-polar Binary Gas Using Neural Networks and Multiple Linear Regressions [PDF]

open access: yesKemija u Industriji, 2019
In the current study, an artificial neural network (ANN) and multiple linear regressions (MLR) have been used to develop predictive models for the estimation of molecular diffusion coefficients of 1252 polar and non-polar binary gases at multiple ...

Physico-chemical phenomena in thin films and at solid surfaces.

open access: yes, 2007
The book is devoted to the consideration of the different processes taking place in thin films and at surfaces. Since the most important physico-chemical phenomena in such media are accompanied by the rearrangement of an intra- and intermolecular ...

Application of terahertz spectroscopy to time-dependent chemical-physical phenomena

open access: yes, 2009
We present here a “proof of concepts” experiment that has been realized to show that time-dependent phenomena can be successfully studied in the terahertz region in a non pump−probe configuration.

Students' Mental Models of Chemical Reactions

open access: yes, 2013
Previous research on topics such as atomic structure and chemical bonding indicates that students’ mental models are often inconsistent with the scientific models, which may impede learning of advanced concepts.
