“I chose chemistry as a career because it is so beautiful and yet still mysterious. I decided to be a chemist when I was 10 years old and I have never to this day regretted that rather early decision. I would not want to use whatever luck I might have for the lottery but rather would like to use it for my work in chemistry ...” This and more about Hisashi Yamamoto can be found on page 5678.

  Synthetic Uses of Ammonia in Transition-Metal Catalysis
  
  Although ammonia (NH₃) is a cheap, abundant, and readily available nitrogen source, it has rarely been used in transition-metal catalysis, due to several obstacles. However, significant advances in the metal-mediated utilization of ammonia have been made recently. This review presents the most recent examples in metal-mediated amination and other relevant reactions with ammonia or ammonium salts. [Microreview]

Most Cited

Angewandte's list of most cited articles has been updated. The new list covers articles published in 2010/11 and was generated from Thomson–Reuters Web of Knowledge. There are separate lists for Communications and all article types. Interestingly, there seems to be little overlap between highly cited and highly downloaded articles.

Catalyst Keeps Fruit Fresh Longer

Even at low temperatures, platinum nanoparticles on a support catalyze breakdown of ethylene

Ripening fruit, vegetables, and flowers release ethylene, which works as a plant hormone. Ethylene accelerates ripening, so other unripened fruit also begins to ripen—fruit and vegetables quickly spoil and flowers wilt. In the journal Angewandte Chemie, Japanese researchers have now introduced a new catalytic system for the fast and complete degradation of ethylene. This system could keep the air in warehouses ethylene-free, keeping perishable products fresh longer.
