Nucleic acids (NAs) proved to be valuable chiral scaffolds for precise arrangement of desired molecular components into chiral, periodically patterned nanosystems.
The devices could give scientists a better tool for understanding healthy and diseased heart tissue, specifically how the precise arrangement of cells is necessary for the heart to function properly, says Kenneth Chien, director of the Massachusetts General Hospital Cardiovascular Research Center.
Fears that Morsi's re-emergence might reinvigorate his supporters have led Egypt's authorities to keep quiet about the precise arrangements for his trial.
But mere complexity in contexts not taken to involve artifacts (the precise arrangement of pine needles on a forest floor, for instance) does not seem to have that same force.
The ultimate bottom-up approach for the construction of functional nanosystems requires the precise arrangement of atoms and molecules in three dimensions.
The emitted light, Pollock found, can reveal important details about molecular bonds that are useful for understanding catalysis and other chemical reactions, the precise arrangement of atoms in molecules, and the configuration of their electrons.
They are emerging tools for the design of structured porous materials having a precise arrangement of functional groups within pores of controlled size and shape.
Paulo Climachauska's "Ghost," a precise arrangement of glass panes, lengths of white fabric and drinking glasses, is like a set-up for an experiment in parapsychology.
Just as the Morse Code consists of three simple signals a dash, a dot, and a space the precise arrangement of which suffices to convey coded messages, so the precise arrangement of the bases in DNA contains and conveys the information for the synthesis and assembly of cell components.
Rapid and precise arrangement of cells into functional tissue constructs remains a challenge in tissue engineering.
The precise arrangement of microscopic objects is critical to the development of functional materials and ornately patterned surfaces.
