Physicists have discovered a room-temperature transition between 1D and 2D electrical conduction states in the topological insulator bismuth iodide.

Barcode imagers (also known as digital or area imagers) read both 1D and 2D barcodes using sensors that have rows of cells. They’re proliferating with 2D barcodes that embed more ...
