Abstract: Methods of making a semiconductor layer from nanocrystals are disclosed. A film of nanocrystals capped with a ligand can be deposited onto a substrate; and the nanocrystals can be irradiated with one or more pulses of light. The pulsed light can be used to substantially remove the ligands from the nanocrystals and leave the nanocrystals unsintered or sintered, thereby providing a semiconductor layer. Layered structures comprising these semiconductor layers with an electrode are also disclosed. Devices comprising such layered structures are also disclosed.

Abstract: A multipurpose beehive access structure includes a housing designed to be placed on top of a standard beehive box. The housing includes a bottom plate with a central aperture through which frames in the beehive box below may be accessed. A removable cover assembly includes a cover plate for covering the central aperture. A queen cage aperture is provided in the cover plate. A queen cage placed in the queen cage aperture rests on top of the frames below. The queen cage aperture provides a passageway between the queen cage and the interior of the beehive to allow bees to access the queen cage. A multi-position vent block has a passageway that provides ventilation and a second entrance to the beehive when positioned between a side aperture and a bottom aperture in the housing. The vent block may also be positioned to close off the second entrance.

Abstract: A beehive comprises a main housing, a primary entrance housing that is rotatably attached to the main housing, and a rotation element for rotating the main housing about its rotational axis between vertical and horizontal positions. The main housing includes chambers for holding honey frames and brood frames. The primary entrance housing includes a primary entrance slot that allows ingress and egress of bees into and out of the primary entrance housing. A primary entrance tube connects the main housing to the primary entrance housing. The primary entrance tube provides a path of travel for bees to move between the primary entrance housing and the main housing. In this configuration, the bees may freely move from the exterior of the beehive, through the primary entrance slot into the primary entrance housing, and through the primary entrance tube into the chambers of the main housing.
