Publication number: 20200146284Abstract: The disclosure relates to a method for treating an active beehive infested with pests. The method includes delivery of an oligomeric polyester including polyol backbone units, diacid backbone units, and formic acid capping units. Hydrolysis of the oligomeric polyester in the beehive upon exposure to environmental water to release formic acid and diacid over time, which kill the pests. The released formic acid is a relatively volatile liquid, allowing it to reach pests essentially anywhere in the hive. The diacid (such as oxalic acid) is generally a non-volatile solid, but it can be transported throughout the hive via normal bee movement within the hive, thus reaching pests beyond the initial point of application.Type: ApplicationFiled: November 14, 2019Publication date: May 14, 2020Inventors: Edmund J. Stark, Patrick B. Smith, Daniel R. Henton, Tracy Zhang

Patent number: 10392317Abstract: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose, starch, sugar) and ethylene in the presence of a catalyst. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF), which may be converted into para-xylene by cycloaddition of ethylene to DMF. Para-xylene can then be oxidized to form terephthalic acid.Type: GrantFiled: September 13, 2013Date of Patent: August 27, 2019Assignee: MICROMIDAS, INC.Inventors: Makoto N. Masuno, Ryan L.
