Facilitating the Isolation of Polar Natural Products: Mild 1,1’‐Carbonyldiimidazole‐Enabled Method for Derivatization of Acids and Alcohols

European Journal of Organic Chemistry, Accepted Article.
Many secondary metabolites containing carboxylic acid and alcohol functional groups are highly polar and can be difficult to purify and isolate from complex extracts obtained from natural sources. The conversion of these natural products to their corresponding alkyl esters/ carbonates under mild conditions can simplify their purification and isolation.

Policy Entrepreneurs and the Design of Administrative Reform: A Conceptual Framework and the Israeli Case

European Policy Analysis, EarlyView.
ABSTRACT What is the role of policy entrepreneurs in promoting the design of public administrative reform? We present a conceptual framework for assessing the influence of policy entrepreneurs on public administrative reform. We start by proposing a typology of the various policy entrepreneurs active in the administrative reform arena.

Creativity and its link to epilepsy

Epilepsia Open, EarlyView.
Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our
