The fabrication of functional materials via grain growth engineering implicitly relies on altering the mobilities of grain boundaries (GBs) by applying external fields. Although computer simulations have alluded to kinetic roughening as a potential mechanism for modifying GB mobilities, its implications for grain growth have remained largely unexplored owing to difficulties in bridging the wide...

Gel electrophoresis is the standard method to separate, identify and purify nucleic acids. SSCP detects single base changes by altered mobility of single-stranded segments electrophoresed through non-denaturing polyacrylamide gels. Herein, changes in electrophoretic mobilities due to single base substitutions were measured for single-stranded segments of lengths ranging from 333 to 547 nt. A 48...

Achieving bulk-like charge carrier mobilities in semiconductor nanowires is a major challenge facing the development of nanowire-based electronic devices. Here we demonstrate that engineering the GaAs nanowire surface by overcoating with optimized AlGaAs shells is an effective means of obtaining exceptionally high carrier mobilities and lifetimes. We performed measurements of GaAs/AlGaAs core-s...

Mobilities in helium gas for isomers belonging to the major structural families of carbon clusters identified in drift tube studies ~chains, monocyclic and bicyclic rings, graphite sheets, and fullerenes and their dimers! have been evaluated by trajectory calculations employing a realistic ion-He interaction potential. For all the species considered, the agreement between the measured and calcu...

The study of drug smuggling has often taken an organizational perspective whereby the structures how is constituted predominate. Building on a growing body scholarship addressing networked complexities this article considers importance distinct infrastructural arrangements. Its primary focus materiality infrastructures, and social, spatial temporal qualities these configurations overlap with li...
