Functional Polyolefins: Synthesis and Energy Storage Applications
Abstract. This chapter discusses our research into the functionalization of polyolefins (PE, PP etc.) that contain polar groups (such as OH and NH 2) in the side chains and chain end, as well as polyolefin graft and block copolymers containing both a polyolefin block and functional polymer blocks (acrylic and methacrylate polymers).

Cranes are a familiar fixture of practically any city skyline, but one in the Swiss City of Ticino, near the Italian border, would stand out anywhere: It has six arms. This 110-meter-high starfish of the skyline isn''t intended for construction. It''s meant to prove that renewable energy can be stored by hefting heavy loads and dispatched by releasing them.

Abstract. Free radicals play a key role in many physiological decisions in cells. Since free radicals are toxic to cellular components, it is known that they cause DNA damage, contribute to DNA instability and mutation and thus favor carcinogenesis. However, nowadays it is assumed that free radicals play a further complex role in cancer.
