In biological systems, nanoscale molecular motors can generate forces from spontaneous reactions of energy-rich molecules, mostly adenosine triphosphate (ATP), to convert chemical energy into mechanical movement. These motors are roughly 10 nm in size, take steps of a few nanometers, and can exert forces in the piconewton range. [ 1 , 2 ] However, to effi ciently design and construct nanoscale ...

The Chief Executive of the Government of Hong Kong Special Administrative Region (HKSAR) has stated in the Policy Address 2008-09 that the Government will promote a low carbon economy in the HKSAR. One of the effective and proven means to achieve this goal is through energy effi ciency enhancement. Incorporation of a district cooling system in the new Kai Tak Development to provide air conditio...

87 0. Take Home Message The effi ciency of energy and protein utilization in the rumen may be improved through the manipulation of microbial population. Antibiotic ionophores have been very successful in improving these effi ciencies, but its use in animal feeds is facing reduced social acceptance. For this reason, other alternatives to control specifi c microbial populations are currently bein...

Small-molecule photovoltaic cells using diindenoperylene (DIP) as a new donor material in combination with the fullerene C 60 as an electron acceptor are demonstrated. In addition to the successful application in planar and bulk heterojunction devices, a comprehensive analysis including structural studies, the determination of the energy level alignment and electrical transport investigations i...

Additionally, organic crystals are promising in their own right due to the effi cient carrier and energy transport properties associated with their long-range order. In particular, crystalline and polycrys...

T he idea of green high-performance computing (HPC) has been gaining traction over the past fi ve years. In November 2008, the Green 500 list (www.green500.org) was introduced to “raise awareness about power consumption, promote alternative total cost of ownership performance metrics, and ensure that supercomputers only simulate climate change and not create it.” The Green 500 lists the world’s...
