Abstract: Methods for forming black phosphorus alloys and exfoliating black phosphorus alloys. A method for forming black phosphorus alloys includes providing phosphorus inside a vessel and providing an element inside the vessel. Media is provided inside the vessel and the phosphorus, the element, and the media are sealed under a gas within the vessel. The phosphorus and the element are mechanically milled with the media to produce black phosphorus that is covalently bonded with the element. A method for exfoliating a black phosphorus alloy includes mixing a milled black phosphorus alloy with a solvent and mixing a milled black phosphorus alloy with a solvent. The milled black phosphorus alloy and solvent mixture are then extracted from the milling apparatus, which may be a planetary ball mill, a vibratory mill, a tumbler ball mill, a mixer mill, a rod mill, an attrition mill, or a shaker mill.

Abstract: The bedding article comprises a plurality of channels which extend longitudinally or laterally of the featherbed and into which fill can be blown. Each channel is divided into two longitudinal portions, accomplished by a line of lateral stitching across the channel. The two portions have different lengths, with the two lengths alternating from end to end for adjacent channels.
