    摘要: Amino acid-based poly(ester urea)s (PEU) are emerging as a class of polymers that have shown promise in regenerative medicine applications. Embodiments of the invention relate to the synthesis of PEUs carrying pendent “clickable” groups on modified tyrosine amino acids. The pendent species include alkyne, azide, alkene, tyrosine-phenol, and ketone groups. PEUs with Mw exceeding 100k Da were obtained via interfacial polycondensation methods and the concentration of pendent groups was varied by copolymerization. The incorporation of derivatizable functionalities is demonstrated using 1H NMR and UV-Vis spectroscopy methods. Electrospinning was used to fabricate PEU nanofibers with a diameters ranging from 350 nm to 500 nm. The nanofiber matricies possess mechanical strengths suitable for tissue engineering (Young's modulus: 300±45 MPa; tensile stress: 8.5±1.2 MPa). A series of bioactive peptides and fluorescent molecules were conjugated to the surface of the nanofibers following electrospinning using bio-orthogonal reactions in aqueous media.

    摘要: The present invention provides a ceramic-glass composite electrode and a fluorescent lamp having the same. The ceramic-glass composite electrode according to the present invention is a ceramic-glass composite, which is disposed at the ends of a glass tube of the fluorescent lamp. A stopper is disposed at the end of the glass tube for pushing against the ceramic-glass composite electrode and limiting the position of the ceramic-glass composite electrode slipped on the glass tube. Thereby, flowing of adhesives into the glass tube is avoided when the adhesives are used for gluing the glass tube and the ceramic-glass composite electrode, and hence extending the lifetime of the fluorescent lamp.

    摘要: A method of forming a silicon dioxide gate insulator layer on the surface of a native oxide free semiconductor substrate, has been developed. After performing wet clean procedures used to remove organic contaminants, as well as inorganic contaminants from a semiconductor substrate, a first native oxide layer formed on the surface of the semiconductor substrate as a result of the wet clean procedures is removed via a hydrofluoric acid solution. The hydrofluoric acid procedure results in fluoride ions now located on the surface of the semiconductor substrate. Insertion of the semiconductor substrate into an anneal—oxidation chamber results in a second native oxide formed on the surface of the semiconductor substrate, with the thickness of the second native oxide limited by the presence of the fluoride ions on the surface of the semiconductor substrate. An anneal procedure performed at a temperature greater than 1000° C., results in removal of the second native oxide as well as removal of the fluoride ions. A thermal oxidation procedure is performed in situ, in the anneal—oxidation chamber, resulting in the growth of a silicon dioxide gate insulator layer on the native oxide free surface of the semiconductor substrate.

    摘要: A multi-phase clock generator including a first delay locked loop, a reference signal generator and a second delay locked loop is provided. The first delay locked loop generates 2N phase clock signals according to an input clock signal, so as to equally divide a clock period of the input clock signal into 2N predetermined phases, where N is a positive integer. The reference signal generator selects two phase clock signals according to a digital signal, and adjusts an output ratio of the two phase clock signals in 2M clock periods to serve as a reference clock signal. The second delay locked loop delays a first phase clock signal according to a phase difference between the reference clock signal and an output clock signal. In this way, each predetermined phase is further equally divided into 2M sub-phases, so that the multi-phase clock generator has 2(N+M) phase selections.
