摘要： A turbine engine airfoil includes a three-pass serpentine shaped cooling cavity including a leading edge chamber, an oversized intermediate chamber, and a trailing edge chamber in flow communication. The cavity further includes a combination of a plurality of ribs and a plurality of pins, a purge air swirler, a turning vane, and a metering partition which mixes the high pressure air and provides increased air cooling and uniform flow control in the airfoil. The metering partition provides a decrease of the air pressure in the trailing edge chamber allowing for an increase in the number of trailing edge slots.

摘要： In one aspect, the present invention is generally directed to methods for measuring distribution of lengths of a collection of carbon nanotubes. In particular, the present teachings provide an indicator for length-based separation of carbon nanotubes (CNTs) via conjugation of one or more biomolecules onto the surfaces of the nanotubes. As discussed in more detail below, in some embodiments, such a method can include conjugating a biomolecule to the carbon nanotubes and subject the conjugated carbon nanotubes to silver-stained gel electrophoresis to separate the conjugated carbon nanotubes based on their lengths.

摘要： Some embodiments provide methods and systems for creating ladder/standards as quality control tools for length-based separation of carbon nanotubes; determining the length purity; or measuring distribution of lengths of a collection of carbon nanotubes. Some embodiments further provide methods and systems for dispersing carbon nanotubes by conjugation of the carbon nanotubes with biomolecule moieties, specifically proteins. Further, some embodiments provide an indicator for length-based separation of carbon nanotubes via conjugation of one or more biomolecules onto the surfaces of the nanotubes. In some embodiments, such a method can include conjugating a biomolecule to the carbon nanotubes and subjecting the conjugated carbon nanotubes to silver-stained gel electrophoresis to separate the conjugated carbon nanotubes based on their lengths.

摘要： Methods and devices for detecting a target agent of interest, e.g., a pathogen, in a sample are described herein. In some embodiments, a sensor is provided that can include a substrate, a graphene layer disposed on a surface of said substrate, and a protein bound to said graphene layer. The protein can be capable of binding to one or more target agents of interest, e.g., pathogens, etc. The binding of the protein to the one or more target agents of interest can generate a change in an electrical property of the graphene layer.

摘要： An improved cooling passage configuration for a gas turbine engine airfoil is disclosed for enhancing convective cooling over that afforded by conventional wall turbulator ribs. An internal cooling passage bounded by pressure and suction side walls and at least one partition has raised turbulator ribs disposed on at least one side wall and the partition. A side wall turbulator rib extends over at least a portion of the side wall and abuts the partition. A turbulator rib disposed on the partition extends from a point spaced from the wall rib to the opposed side wall. The gap formed between the partition rib and wall rib accelerates a coolant flow passing therethrough, locally enhancing convective heat transfer. Partition ribs may be aligned with or offset from the wall ribs in the spanwise direction and may be normal to the primary direction of cooling flow or angled thereto. Convective heat transfer is particularly enhanced in flow passages having cavity height blockage due to wall ribs greater than about 10%.
摘要翻译： 公开了一种用于燃气涡轮发动机翼型的改进的冷却通道构造，用于增强由传统的壁湍流肋提供的对流冷却。 由压力和吸力侧壁和至少一个隔板限定的内部冷却通道具有设置在至少一个侧壁和隔板上的湍流肋。 侧壁湍流肋在侧壁的至少一部分上延伸并邻接隔板。 设置在隔板上的湍流肋从与壁肋间隔开的位置延伸到相对的侧壁。 在分隔肋和壁肋之间形成的间隙加速了通过其中的冷却剂流，局部增强了对流热传递。 分隔肋可以在翼展方向上与壁肋对准或偏离，并且可以垂直于冷却流的主要方向或与其成角度。 由于壁肋大于约10％，具有腔高度阻塞的流动通道，对流传热特别增强。

摘要： A rotating particulate trap is disclosed, which may find application in diesel engines, air conditioning systems, industrial air-filters and the like. The invention includes a disk or cylinder which is formed from material suitable for filtering particulates which are present in the exhaust gases of diesel engines, gas turbines, industrial air or other particulate laden gases. The disk is mounted transversely in the exhaust duct of a diesel engine and in a fresh air duct which is disposed parallel to the exhaust duct. As the disk rotates within the exhaust duct, it filters particulates from the exhaust gases of the diesel engine. The filtered particulates are expelled from the disk by fresh air blowing in the air duct as the disk rotates within the air duct. The fresh air is blown in the air duct in a direction opposite to the flow of exhaust gases within the exhaust duct by a fan or compressor or compressed air jets. The counterflow arrangement of fresh air and combustion gases enhances the effectiveness of particulate removal as the disk rotates between the exhaust duct and the fresh air duct. Particulates expelled from the disk are blown into a filter bag which is attached to the end of the fresh air duct.
