  • Patent number: 9040121
    Abstract: Vacuum deposited thin films of material are described to create an interface that non-preferentially interacts with different domains of an underlying block copolymer film. The non-preferential interface prevents formation of a wetting layer and influences the orientation of domains in the block copolymer. The purpose of the deposited polymer is to produce nanostructured features in a block copolymer film that can serve as lithographic patterns.

    Abstract: Highly dispersed lithium titanate crystal structures having a thickness of few atomic layers level and the two-dimensional surface in a plate form are supported on carbon nanofiber (CNF). The lithium titanate crystal structure precursors and CNF that supports these are prepared by a mechanochemical reaction that applies sheer stress and centrifugal force to a reactant in a rotating reactor. The mass ratio between the lithium titanate crystal structure and carbon nanofiber is preferably between 75:25 and 85:15. The carbon nanofiber preferably has an external diameter of 10-30 nm and an external specific surface area of 150-350 cm2/g. This composite is mixed with a binder and then molded to obtain an electrode, and this electrode is employed for an electrochemical element.

    Abstract: A system for the physical manipulation of free magnetic rotors in a circulatory system using a remotely placed magnetic field-generating stator is provided. In one embodiment, the invention relates to the control of magnetic particles in a fluid medium using permanent magnet-based or electromagnetic field-generating stator sources. Such a system can be useful for increasing the diffusion of therapeutic agents in a fluid medium, such as a human circulatory system, which can result in substantial clearance of fluid obstructions, such as vascular occlusions, in a circulatory system resulting in increased blood flow. Examples of vascular occlusions targeted by the system include, but are not limited to, atherosclerotic plaques, including fibrous caps, fatty buildup, coronary occlusions, arterial stenosis, restenosis, vein thrombi, arterial thrombi, cerebral thrombi, embolisms, hemorrhages, other blood clots, and very small vessels.

  • Publication number: 20140113356
    Abstract: The present invention disclosed a nano-electrode based transparent chip, which is applicable to perform a micro fluidic substance diffused through a specific region of a single cell membrane by localized electroporation technique with membrane reversibility. The chip comprises a silicon-based layer, different structural layers, an insulating layer and a micro fluidic layer. When the individual single cell was placed on the gap between a plurality of triangular-shaped nano-electrodes with nano-tip, then electric field can intense on a specific region of the individual single cell causes the formation of nano-pores on the membrane, resulting to deliver drugs, DNA molecules from outside of the cell to the inside of the cell with a high transfection rate and a high cell viability. This technique not only generates well-controlled nano-pores to allow rapid recovery of the cell membrane, but also provides clear optical path for potentially monitoring/tracing the drugs into the cell.

  • Publication number: 20140083473
    Abstract: Self-cleaning banknotes are provided using coatings, inks and additives which are photo-active and catalytic to reactions which are effective in breaking up organic contaminants or dirt to allow for the self-cleaning of banknotes by ambient light exposure as well as the cleaning of processed banknotes using equipment with more intense optical excitation, thus increasing their usable life. The invention is usable with all substrates and particularly polymeric substrates such as biaxially-oriented polypropylene (BOPP). The invention further discloses a system which allows a certain class of fitness parameters to cause these banknotes to be redirected to a cleaning module, be reevaluated, and then either returned to circulation or rejected and/or destroyed. In addition, inks which are photo-catalytic can be used for extending the life of the banknotes in printed regions.
