[1] SiI 4 is a precursor to silicon amides of the formula Si(NR 2) 4 (R = alkyl). [2] It has also been of interest in the manufacture and etching of silicon in microelectronics.
The absorption value for normal-incident light on graphene in vacuum would then be given by πα / (1 + πα/2) 2 or 2.24%, and the transmission by 1 / (1 + πα/2) 2 or 97.75% (experimentally observed to be between 97.6% and 97.8%). The reflection would then be given by π 2 α 2 / 4 (1 + πα/2) 2 .

Pullulan is a polysaccharide consisting of maltotriose units, also known as α-1,4- ;α-1,6-glucan'. Three glucose units in maltotriose are connected by an α-1,4 glycosidic bond, whereas consecutive maltotriose units are connected to each other by an α-1,6 glycosidic bond. Pullulan is produced from starch by the fungus Aureobasidium pullulans.
