Novel photochromic 2,2´-bithiophene azo dyes [PDF]

, 2009
The photochromic behaviour of two series of 2,2’-bithiophene azo dyes in THF solutions was studied. The photochromic properties and colour constancy were strongly dependent on the substitution pattern of the dyes.

On the unlikelihood of specific long range forces in immunologic and enzymatic reactions [PDF]

, 1950
In the past few years, a great many experiments have been performed by Rothen (24, 25) which he has interpreted as suggesting that antigen and antibody, and enzyme and substrate proteins, can react specifically, although separated by distances of ...

National Environmental Policies and Corporate Green Innovation: The Mirroring Versus Substitution Hypotheses

Business Strategy and the Environment, EarlyView.
ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...
