We developed means to produce wafer scale, high-quality graphene films as large as 3 in. wafer size on Ni and Cu films under ambient pressure and transfer them onto arbitrary substrates through instantaneous etching of metal layers. We also demonstrated the applications of the large-area graphene films for the batch fabrication of field-effect transistor (FET) arrays and stretchable strain gauges showing extraordinary performances. Transistors showed the hole and electron mobilities of the...

Dietary intervention with a unique prebiotic nondigestible carbohydrate mixture has been shown to reduce the development of allergic disease in infants at risk. In this study, the involvement of CD25+ regulatory T-cells (Treg) in the carbohydrate-induced effects was investigated in mice orally sensitized with whey using adoptive transfer experiments. Donor mice were sensitized with whey and fed a diet containing short-chain galacto-, long-chain fructo- and acidicoligosaccharides, or a...

Respiratory microorganisms capture energy for growth and maintenance as they transfer electrons from energy sources to appropriate electron acceptors. Controlling the availability of electron donor and acceptor pairs provides opportunities for investigating fundamental aspects of energy transformation and distribution in defined and un defined microbial cultures. For example, we have noted that in all bacteria investigated to date electron acceptor limitation prompts the production of...
