Conductance quantization suppression in the quantum Hall regime
Nature Communications, 2018 Conductance quantization is the hallmark of non-interacting confined systems. The authors show that the quantization in graphene nanoconstrictions with low edge disorder is suppressed in the quantum Hall regime.

Conversion of Gasoline Vehicles to CNG Hybrid Vehicles (CNG-Electric Vehicles) [PDF]
Research Journal of Applied Sciences, Engineering and Technology, 2013 The aim of this study is investigation of the feasibility and advantages of using the natural gas as an alternative to gasoline as a fuel for hybrid electric vehicles. Operating CNG vehicles are really beneficial in the Middle East region considering the fact that gasoline is offered at a heavily subsidized price and therefore, by converting a ...

Angewandte Chemie, EarlyView.Cyclic adenosine monophosphate (cAMP) is a key cellular second messenger. Adenylyl cyclase converts emissive isomorphic nucleoside triphosphates into fluorescent cAMPs. cthAMP displays unusually high brightness compared to thATP, its precursor, enabling real‐time monitoring of enzymatic reactions.
