  • Publication number: 20230391709
    Abstract: The present disclosure relates to a method for preparing an esterified alkane. The method includes mixing a gaseous alkane with oxygen or air to obtain a mixed gas; adding a chlorine-containing catalyst and/or a nitrogen-containing catalyst to a light-transmission reaction vessel; then adding the mixed gas, an acid and a solvent in sequence to carry out a reaction under ambient pressure and an illumination condition; and then conducting analysis to obtain an NMR yield, followed by extraction, drying, filtration, distillation under reduced pressure and separation by column chromatography to obtain an esterified alkane. The present disclosure has the advantages that the reaction can be carried out under the conditions of ambient temperature and pressure with a cheap and safe chlorine-containing compound and a nitrogen-containing compound as a catalyst and air as an oxidant, and the method has energy-saving and economic effects, convenient and safe operation and environmental friendliness.

  • Patent number: 11254943
    Abstract: The present invention relates to the field of molecular biology and more particularly to promoters useful for metabolic engineering in yeast or fungi for the production of biobased chemicals with broad applications. Intron-containing promoters with strong activity during oil-accumulation stages are particularly useful for genetic engineering in yeast and fungi, particularly Rhodosporidium or Rhodotorula genera. Such promoter are capable of driving strong expression of RNA or proteins in species of the Rhodosporidium or Rhodotorula genera.

  • Publication number: 20210227695
    Abstract: A method is provided for forming a printed circuit board (PCB) assembly. The method may include drilling a first plurality of vias having a first diameter in a PCB and filling the first plurality of vias to form a first plurality of plated or filled vias. The method may also include drilling a second plurality of vias having a second diameter in the PCB, and filling the second plurality of vias to form a second plurality of plated or filled vias. The first plurality of plated or filled vias is mixed with the second plurality of plated or filled vias such that the spacing between the first plurality of plated or filled vias and the second plurality of plated or filled vias is less than the first diameter and the second diameter.
