Abstract:
A method of forming a periodic array of nano-scale objects using a block copolymer, and nano-scale object arrays formed from the method are provided. The method for forming the arrays generally includes the steps of depositing a block copolymer of at least two blocks on a substrate to form an ordered meso-scale structured array of the polymer materials, forming catalytic metal dots based on the meso-scale structure, and growing nano-scale objects on the catalytic dots to form an ordered array of nano-scale objects.

This invention relates to a duct suitable for use in an air circulation system, the duct comprising an inner gas-permeable layer and an outer gas-impervious layer, and one or more spaces therebetween.
Abstract:
A method and system provide for the control of resource allocation within a build-to-order manufacturing environment. One example embodiment of a method according to the present disclosure includes an operation for monitoring a work-in-process (WIP) profile that represents dynamic attributes of an area in a manufacturing facility. A user interface in a control center for the manufacturing facility may be automatically updated to depict one or more of the dynamic attributes in substantially real time, based on one or more of the WIP profiles. After the user interface is updated, user input that specifies a desired reallocation of resources for the manufacturing facility may be received. The user input may trigger communications with one or more areas in the manufacturing facility to implement the desired reallocation of resources. Alternative embodiments may include additional or alternative features, such as features for error detection and recovery.
Abstract:
A smoke removal apparatus, capable of operating in a confined space without ventilation of the apparatus to the atmosphere to provide removal of smoke from air to be treated. The apparatus comprises one or more of the following filters: a mechanical filter (2); an electrostatic filter (3); and/or a chemical filter (4). The apparatus is arranged to collect smoke from a relatively higher position (5), pass smoke through the one or more filters/and expel treated air to a relatively lower position (6).
Abstract:
A textile duct for an air circulation system, the duct having an inner gas-permeable layer and an outer gas-impervious layer, and one or more spaces therebetween. An air circulation system having one or more ducts and one or more air treatment units and/or air handling units. The ducts are formed from laminates suitable for forming a duct for an air circulation system, the laminate has an inner gas-permeable layer and an outer gas-impervious layer, and one or more spaces therebetween.
Abstract:
Described is a Schottky diode using semi-conducting single-walled nanotubes (s-SWNTs) with titanium Schottky and platinum Ohmic contacts for high-frequency applications. The diodes are fabricated using angled evaporation of dissimilar metal contacts over an s-SWNT. The devices demonstrate rectifying behavior with large reverse-bias breakdown voltages of greater than −15 V. In order to decrease the series resistance, multiple SWNTs are grown in parallel in a single device, and the metallic tubes are burnt-out selectively. At low biases, these diodes showed ideality factors in the range of 1.5 to 1.9. Modeling of these diodes as direct detectors at room temperature at 2.5 terahertz (THz) frequency indicates noise equivalent powers (NEP) comparable to that of the state-of-the-art gallium arsenide sold-state Schottky diodes, in the range of 10-13 W/square-root (√) Hz.
