The present invention provides instrumentation that facilitates access to both sides of the vertebral body from a single access point. More particularly, the present invention provides bendable access devices that can be steered so as to traverse the vertebral body from the point of entry into the vertebral body, through the cancellous bone within the vertebral body, and to the contralateral side of the vertebral body. This steerability is provided by forming the access device with a series of slots, grooves, or notches in the side of the access device near the distal end of the access device, which slots, grooves, or notches reduce the bending stiffness of the access device. As a result, the distal end of the access device bends as it is being advanced into the vertebral body.

Additional systems based on this approach (e.g., surface plasmon resonance absorption and alloying sensors and nanocatalysts) are described.

According to an embodiment of the invention, a method for repairing a coated high pressure turbine blade, which has been exposed to engine operation, to restore coated airfoil contour dimensions of the blade, is disclosed. The method comprises providing an engine run high pressure turbine blade including a base metal substrate made of a nickel-based alloy and having thereon a thermal barrier coating system. The thermal barrier coating system comprises a diffusion bond coat on the base metal substrate and a top ceramic thermal barrier coating comprising a yttria stabilized zirconia material. The top ceramic thermal barrier coating has a nominal thickness t. The method further comprises removing the thermal barrier coating system, wherein a portion of the base metal substrate also is removed, and determining the thickness of the base metal substrate removed. The portion of the base metal substrate removed has a thickness, Δt. The method also comprises reapplying the diffusion bond coat to the substrate, wherein the bond coat is reapplied to a thickness, which is about the same as applied prior to the engine operation; and reapplying the top ceramic thermal barrier coating to a nominal thickness of t+Δt, wherein Δt compensates for the portion of removed base metal substrate. Advantageously, the coated airfoil contour dimensions of the high pressure turbine blade are restored to about the coated dimensions preceding the engine run.

The invention disclosed herein relates to elastomeric articles such as medical or industrial gloves coated by antimicrobial compositions and protected by water-resistant packaging. Antimicrobial gloves are useful in methods for reducing nosocomial infection by Gram positive bacteria, Gram negative bacteria, fungi, and viruses. Packaged gloves maintain quick-kill activity against microbes, even after extended storage. In a preferred embodiment, the present invention provides a method of packaging which protects the antimicrobial activity of a glove during storage and transportation by shielding the glove from warm and/or humid environments. Alternatively, the present invention provides a system comprising an antimicrobial glove and packaging as a means for maintaining a low level of humidity in the vicinity of the glove.

The invention relates to a process for coating ceramic honeycomb bodies with a catalyst suspension comprising catalyst components as solids and/or in dissolved form in a carrier liquid. Parallel flow channels run through the honeycomb bodies. The walls of the flow channels have an open pore structure. To coat the channel walls and in particular also the interior surfaces of the pores with the catalyst suspension, the entry and exit end faces of the vertically aligned honeycomb bodies are each brought into contact with a perforated mask, with the perforated masks being arranged so that the open regions of the perforated mask on the one end face are opposite the closed regions of the perforated mask on the other end face and vice versa. The catalyst suspension is then pumped or sucked from below into the honeycomb bodies until it exits at the upper end face. Excess suspension is then removed by blowing-out or sucking-out, the contact with the perforated masks is released and the honeycomb body is calcined to fix the coating.

We discovered that the use of certain dopants or dopant moieties in polymeric coating formulations, that when applied over carbon nanotubes, unexpectedly decrease the measured electrical resistance of the coated carbon nanotubes (CNTs), when measured through the coating, even though the polymer coatings themselves do not have bulk conductivity. CNT compositions with enhanced electrical conductivity and methods of making such compositions are described. The CNTs are preferably coated with a dopant or dopant moiety having a HOMO energy of −7.0 eV or lower.
