Abstract:
The present invention discloses a wound dressing which may be a double-layer wound dressing, comprising a polymer material layer in combination with anti-infective antibiotics or anti-infective Chinese herb medicine at the upper layer of the wound dressing, and a porous carbon material layer capable of loading with skin-associated epithelial cells at the lower layer of the wound dressing. The wound dressing with the antibiotics can block effectively the invasion of bacteria in the external environment, thereby preventing the wound from secondary infection. While covering the wound site, the porous carbon material layer with the epithelial cells can thus provide the healthy epithelial cells and attract the surrounding healthy cells to aggregate for secreting collagen so as to promote the wound healing process. According to the present invention, there is an obviously enhancing effect on wound tissue regeneration, restoration and healing, and there is a grant development potential in clinical applications.
Abstract:
A biosensor for quantifying an analyte in a sample and usage thereof are provided. The biosensor includes an insulative substrate, a cover, a sample supply port, an electrode system including at least a working electrode, a counter electrode and a third electrode, and a reaction layer at least formed over the working electrode. The third electrode, used for estimating whether the amount of the sample is sufficient, is disposed nearer to the sample supply port than the counter electrode is. Whether the amount of the added sample is sufficient is estimated by comparing the electrical current value detected between the working electrode and the counter electrode with the electrical current value detected between the working electrode and the third electrode. This invention has a simple structure and produces accurate measurements.
Abstract:
Within a method for forming a silicon layer, there is employed at least one sub-layer formed of a higher crystalline silicon material and at least one sub-layer formed of a lower crystalline silicon material. The lower crystalline silicon material is formed employing a hydrogen treatment of the higher crystalline silicon material. The method is particularly useful for forming polysilicon based gate electrodes with enhanced dimensional control and enhanced performance.

A semiconductor structure includes a substrate and a conductive carrier-tunneling layer over and contacting the substrate. The conductive carrier-tunneling layer includes first group-III nitride (III-nitride) layers having a first bandgap, wherein the first III-nitride layers have a thickness less than about 5 nm; and second III-nitride layers having a second bandgap lower than the first bandgap, wherein the first III-nitride layers and the second III-nitride layers are stacked in an alternating pattern. The semiconductor structure is free from a III-nitride layer between the substrate and the conductive carrier-tunneling layer. The semiconductor structure further includes an active layer over the conductive carrier-tunneling layer.
Abstract:
A system for, and method of using multiple data flows, both transactional and non-transactional, in real time to modify a transaction is disclosed. Further the use of transaction information in real time as a decision factor to trigger a different, non-transactional response, and the combination of the two approaches is disclosed. In particular, a network comprised of a plurality of software modules and databases is capable of combining current POS/POP transaction data, with a variety of other outside data sources to provide improved information for adjusting responses to transactions in real time. More specifically, the network utilizes payer facing systems to analyze the data in combination with well-known POS/POP transaction data and a variety of internal and external systems to combine information and provide modified transactions, related discounts and offers, and other relevant messaging to the payer. In addition, a specific method for analyzing for fraud within hybrid information transactions is disclosed and several examples to illustrate the invention are included.
