Surface Properties of the Polyethylene Terephthalate (PET) Substrate Modified with the Phospholipid-Polypeptide-Antioxidant Films: Design of Functional Biocoatings

Pharmaceutics, 2022
Surface properties of polyethylene terephthalate (PET) coated with the ternary monolayers of the phospholipid 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), the immunosuppressant cyclosporine A (CsA), and the antioxidant lauryl gallate (LG) were ...

Quasi-chemical Theories of Associated Liquids

, 1998
It is shown how traditional development of theories of fluids based upon the concept of physical clustering can be adapted to an alternative local clustering definition.

Qualitative Theory and Chemical Explanation [PDF]

, 2002
Roald Hoffmann and other theorists claim that we we ought to use highly idealized chemical models (``qualitative models'') in order to increase our understanding of chemical phenomena, even though other models are available which make more highly ...

Single-particle properties of topological Wannier excitons in bismuth chalcogenide nanosheets

Scientific Reports, 2023
We analyze the topology, dispersion, and optical selection rules of bulk Wannier excitons in nanosheets of Bi2Se3, a topological insulator in the family of the bismuth chalcogenides.

Specific heat anomaly in the d-density wave state and emergence of incommensurate orbital antiferromagnetic order

, 2001
We study the effect of finite chemical potential on the d-density wave state that has been proposed to explain the pseudogap phenomena in underdoped cuprates. We find that the specific heat anomaly at the transition temperature, below which the d-density

Dynamical tunneling in molecules: Quantum routes to energy flow

, 2007
Dynamical tunneling, introduced in the molecular context, is more than two decades old and refers to phenomena that are classically forbidden but allowed by quantum mechanics.

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

Kemija 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 ...
