Provided is an oxidative polymerization method of flavonoids under alkaline conditions in a one-step process to form polymeric flavonoids. Polymeric flavonoids are noted to not only improve the poor aqueous solubility of monomeric flavonoid, but also provide enhanced antibacterial property. Polymeric flavonoids are shown to be capable of inhibiting the growth of gram-negative bacteria, gram-positive bacteria and MRSA in complex bacterial culture media with superior bacteriostatic ability compared to metal nanoparticles. In addition, it had been demonstrated to inhibit inflammation symptoms in diabetic wounds, and promotes the damaged tissue entering the proliferation phase.

A post segment for a window grille configured to be attached to a window, the window grille comprising at least one grille panel configured for preventing entry or exit of a person through the window, the at least one grille panel comprising two side posts spaced apart by a plurality of crossbars, the post segment comprising: a body having a first end, a second end and a hole in a side of the body; wherein the first end and the second end are configured to allow the first end of one of the post segments to engage the second end of another of the post segments such that a plurality of the post segments can be assembled end-to-end to form each of the two side posts; and wherein the hole in the side of the body is configured to engage an end of one of the plurality of crossbars
摘要:
A semiconductor device comprises a substrate and at least two groups of semiconductor dies stacked above the substrate. Each group of semiconductor dies includes at least a bottom and a top semiconductor die. Each semiconductor die comprises at least one bonding pad aligned along a first edge of the semiconductor die. The at least two groups of semiconductor dies comprise an underlying group of semiconductor dies and an overlying group of semiconductor dies. The bottom semiconductor die of the underlying group is disposed on the substrate while the bottom semiconductor die of the overlying group is disposed directly on the top semiconductor die of the underlying group. Within each group, the first edge of the top semiconductor die is offset from the first edge of the bottom semiconductor die by a group offset length in a first direction. The first edge of the bottom semiconductor die of the overlying group is shifted from the first edge of the bottom semiconductor die of the underlying group by a shift length Lshift in the first direction. The group offset length Lgoffset of the underlying group is greater than or equal to the shift length Lshift of the overlying group.

摘要:
A wire bonded structure for a semiconductor device is disclosed. The wire bonded structure comprises a bonding pad; a conductive bump disposed on the bonding pad, the conductive bump including a concave top surface; and a continuous length of wire mutually diffused with the concave top surface of the conductive bump. The wire electrically couples the bonding pad with a first electrical contact and a second electrical contact different from the first electrical contact.
