  • Nanocrystal structures
    Patent number: 8121162
    Abstract: A structure including a grating and a semiconductor nanocrystal layer on the grating, can be a laser. The semiconductor nanocrystal layer can include a plurality of semiconductor nanocrystals including a Group II-VI compound, the nanocrystals being distributed in a metal oxide matrix. The grating can have a periodicity from 200 nm to 500 nm.
    Type: Grant
    Filed: November 21, 2008
    Date of Patent: February 21, 2012
    Assignee: Massachusetts Institute of Technology

  • Easy opening gable top carton and blank therefor
    Patent number: 5014854
    Abstract: A gable top carton is provided with a flat top wall to facilitate stacking of the carton during storage and transportation. The carton is formed from a single blank of paperboard material provided with an array of score lines to facilitate the folding of various panels formed thereon into the erected carton. The top wall of the flat topped carton includes arrays of perforations disposed therein to define an integral tear strip that is selectively separable from the remainder of the carton. Removal of the tear strip enables panels of the top wall to be rotated upwardly and away from one another to define a unitary pour spout. The pour spout may be repeatedly closed and reopened to provide access to the pourable material as needed.
