Hardening of Water-Glass Paints

Emission of isothiazolinones from water-based paints.

The isothiazolinone preservatives methylisothiazolinone (MI), methylchloroisothiazolinone (MCI), and benzisothiazolinone (BIT) are used in a wide variety of products including paint and cosmetics, and they are known to cause allergic contact dermatitis. Among painters they are one of the most common causes of contact dermatitis. Furthermore, they are all volatile, and severe reactions caused by...

Heating-induced glass-glass and glass-liquid transformations in computer simulations of water.

Water exists in at least two families of glassy states, broadly categorized as the low-density (LDA) and high-density amorphous ice (HDA). Remarkably, LDA and HDA can be reversibly interconverted via appropriate thermodynamic paths, such as isothermal compression and isobaric heating, exhibiting first-order-like phase transitions. We perform out-of-equilibrium molecular dynamics simulations of ...

How a painter paints

Drawing from the seminal definition of the principles of abstract art posed by Wassily Kandinsky in the early years of the twentieth century, and contextualizing that knowledge in contemporary cognitive metaphor theory (Lakoff & Johnson, 1999), the study attempts to arrive at an understanding of how cognitive structure emerges in pragmatic self-observation during the artistic process. Through a...
