  • Patent number: 12334905
    Abstract: Disclosed is an acoustic resonator including a substrate including a first cavity, a first electrode formed above the substrate, a piezoelectric layer formed on one surface of the first electrode, and a second electrode formed on one surface of the piezoelectric layer. Here, the piezoelectric layer includes a longitudinal section not to cover a longitudinal section of the first electrode. Also, the second electrode covers the longitudinal section of the piezoelectric layer and extends to a first interpolar cavity which spaces the first electrode at least partially apart from the piezoelectric layer. A quality factor may be increased by fixing an increase in resistance which occurs due to thin film electrodes.

  • Publication number: 20250134938
    Abstract: The present disclosure relates to a Lactococcus lactis subsp. lactis CAB701 strain having both anti-obesity and immune-promoting activities, an anti-obesity or immune-enhancing food composition containing the same, and an anti-obesity or immune-enhancing vegan fermented milk containing the same. The CAB701 strain of the present disclosure has pancreatic lipase inhibitory activity and can be widely utilized for preventing, ameliorating or treating obesity and for enhancing immunity. Furthermore, it can be used as a starter for fermentation. In addition, since a vegan fermented milk prepared with the CAB701 strain of the present disclosure exhibits a significantly slower decrease in the viable Lactobacillus cell count during the storage period as compared to vegan fermented milks prepared with conventional strains, it can be seen that the CAB701 strain of the present disclosure is useful in the preparation of a vegan fermented milk.
