  • Publication number: 20250196020
    Abstract: The present disclosure provides an equipment for production of butanol and octanol and a triple-effect distillation method, comprising two processes: butanol separation and octanol separation, both processes use same feedstocks to obtain n-butanol, iso-butanol and octanol products through different procedures, respectively, wherein butanol separation process is sequentially divided into hydrogenation, removal of light and heavy components and separation of isomeric; and octanol separation process is sequentially divided into separation of isomeric, hydrogenation and removal of light and heavy components; the removal of light and heavy components for butanol is carried out by a butanol pre-distillation column and a butanol distillation column, and the separation of isomeric for butanol is carried out by a first butanol isomer column and a second butanol isomer column; and the separation of isomeric for octanol is carried out by a first butyraldehyde isomer column and a second butyraldehyde isomer column.

  • Publication number: 20250175258
    Abstract: Methods and systems for down-conversion of high frequency signals in millimeter-wave (mm-wave) communications and for up-conversion of high frequency signals in millimeter-wave (mm-wave) communications. A quantum dot multi-wavelength laser (QD MWL) source generates an optical signal comprising of a plurality of optical channels and allows flexible selection of the optical channels which can be used to generate and process RF signals in higher frequency bands of mm-wave spectrum including K-band, Ka-band V-band, W-band encompassing all 3GPP NR FR2 bands and even THz range depending on the channel spacing.

  • Patent number: 10818817
    Abstract: There is described a cascade-type compact hybrid energy cell (CHEC) that is capable of individually and concurrently harvesting solar, strain and thermal energies. The cell comprises an n-p homojunction nanowire (NW)-based piezoelectric nanogenerator and a nanocrystalline/amorphous-Si:H single junction cell. Under optical illumination of ˜10 mW/cm2 and mechanical vibration of 3 m/s2 at 3 Hz frequency, the output current and voltage from a single 1.0 cm2-sized CHEC was found to be 280 ?A and 3.0 V, respectively—this is are sufficient to drive low-power commercial electronics. Six such CHECs connected in series were found to generate enough electrical power to light emitting diodes or drive a wireless strain gauge sensor node.
