    • Enzymatic synthesis of macrolactones 

      Fortunati, Tancredi (Universita degli studi di Salerno, 2011-02-24)
      Macrolactones are a large and structurally diverse class of compounds. Natural products having a macrolactone structure have been isolated from many natural sources such as plants, insects, marine organism and bacteria. ...

    • Redox proteins for the development of biosensors 

      De Martino, Franco (Universita degli studi di Salerno, 2011-02-21)
      In recent years the field of chemical sensors and optical biosensors has been developed considereably. A biosensor is a device composed of a biological component (Borisov and Wolfbeis 2008) that interacts with a target ...

    • A molecular dymanics view of structure and reactivity 

      Ragone, Francesco (Universita degli studi di Salerno, 2011-02-21)
      The eld of computer simulations has developed into a very important branch of science providing a guess at the interactions between molecules to obtain predictions of properties as accurate as required, subject to ...

    • Efficient distributed load balancing for parallel algorithms 

      Cosenza, Biagio (Universita degli studi di Salerno, 2011-04-29)
      With the advent of massive parallel processing technology, exploiting the power offered by hundreds, or even thousands of processors is all but a trivial task. Computing by using multi-processor, multi-core or many-core ...
