The field of molecules in motion, for which movements and shape changes are triggered and controlled from outside, has been indisputably one of the most rapidly developing areas of the last decade. Clearly, molecular chemists in general are able to elaborate more and more complex species, as beautifully demonstrated by the synthesis of amazingly complicated natural products. For instance, the total...
Mercedes-Benz put the world largest fuel cell vehicle fleet into operation in December 2009. The B-Class F-Cell was produced 200 times under standard production process at Mercedes-Benz facilities and delivered to customers worldwide. During the production phase it was possible to learn more about all the specific challenges to handle high voltage components like batteries and electric drive as well...
In the group of public key algorithms, elliptic curve cryptosystems (or ECC) are widely considered as the best compromise in terms of speed, memory requirement and security level. Recent researches have stressed the possibility of implementing ECC in low-end systems such as the nodes of a wireless sensor network (WSN). The main constraints for such an application are implementation cost and power...
Public key cryptography is widely considered as the best building block for key exchange; different public key algorithms are standardized and used in many applications. Among them, ECC (elliptic curve cryptography) is considered the best solution in terms of security, computational requirements and storage need for secret and public keys. Energy consumption is among the main constraints to be considered...
