Formation and Characterization of Gold Nanoparticles

One-dimensional nanowires are of increasing interest due to their size, physical properties, and other applications in opto-electronics. For example, nanowires have already been used in light-emitting diodes and lasers, photo-detectors, resonant tunneling diodes, field-effect and single-electron transistors, and biochemical sensors. In addition, nanowires are useful because they can be grown almost dislocation-free due to their nano dimension. When dislocation- free nanowires nucleated on the substrate merge to form a continuous film, voids are left underneath, which act as sinks for dislocations, allowing other structures to be grown stress-free on top of the nano-engineered buffer layer.

Carbon Nanotube Thermal Interfaces Enhanced with Sprayed-On Nanoscale Polymer Coatings

As the semiconductor industry continually strives to increase the power density of single-chip packages, thermal management remains a critical challenge toward realizing both performance and reliability metrics. One of the primary bottlenecks inhibiting effective thermal management arises from the several interfaces that can exist between the chip and heat sink. Specifically, the thermal resistance of the thermal interface materials (TIMs) that are currently used to bridge these interfaces must be decreased. Carbon nanotubes (CNTs), with their extraordinarily high axial thermal conductivity, have generated tremendous interest as candidates for providing low-resistance TIMs. A potentially scalable and low-cost process was developed that utilizes spray coating to deposit thin polymer films onto the tips of CNTs for bonding at room temperature.

Lipid Layer-Based Corrosion Monitoring on Metal Substrates

Corrosion is a deforming process that costs the United States Department of Defense (DOD) approximately $23 billion annually and accounts for 23% of all DOD maintenance. Exhaustive efforts have been made towards the detection and diagnosis of this issue; however, the problem persists. The Army’s “Go Green” initiative has opened the door for research into an environmentally friendly, biologically based corrosion monitoring technique. For this reason, novel research is being conducted on the use of lipid layers in corrosion monitoring.

OpenVPX(R) 40G Ethernet + InfiniBand(R) Switch Card

Curtiss-Wright Controls Defense Solutions (Ashburn, VA), a business group of Curtiss-Wright Controls, has introduced the newest member of its Fabric40(TM) family of extremely high-speed 40 Gbps OpenVPX™modules. The new VPX6-6802 Fabric40 Switch is the first rugged, high performance 6U OpenVPX (VITA 65) switch card to provide support for 10/20/40 Gigabit Ethernet (GbE) and SDR/DDR/QDR/FDR-10 InfiniBand®(IB) connectivity to OpenVPX™ systems. Systems built using the VPX6-6802 and complementary Curtiss-Wright Fabric40 system elements will deliver over 2x the performance of previous generation SRIO Gen-2-based systems and 4x the performance of 10 GbE-based systems. The fully rugged VPX6-6802 is available in air-, conduction-, and air flow-through (AFT)-cooled configurations. Designed for use with today’s highest speed switched fabrics, the board provides a combined Data Plane and Control Plane high-performance switch for 6U VPX systems.
