The development of high-throughput screening (HTS) in the past decade generated the capacity to quickly evaluate large numbers of compounds in a variety of assay methodologies.1 In many organizations, this capacity easily exceeded the size of internal compound collections. Efficient utilization of this HTS resource drove the need for an analogous increase in the rate of compound synthesis. This...

Abstract This paper experimentally and numerically investigated the impact test response characteristics of circular honeycomb cores. The experiments were conducted on two different structures aluminum-tube core, square structure star structure. specimens tested in order to find energy absorption, specific crashworthiness behaviors. results revealed that cores with could resist higher load than...

Hybrid photovoltaic/thermal (PV/T) collector, combining photovoltaic cells with a solar thermal collector, can simultaneously convert solar energy into electricity and heat energy. In this paper, a novel photovoltaic/thermal integrated heat pump (PV/T-HP) system was developed, in which the PV/T collector also acted as evaporator of heat pump. Two types of PV/T collectors with conventional coppe...

Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...

Shock tubes have been widely used since the 1950s to study physical phenomena such as shock waves, combustion chemistry, and the response of materiel to blast loading. Recently, laboratory-scale shock tubes driven by oxy-acetylene were described. It was estimated that these shock tubes would not have a significant “jet effect” of expanding gases following the shock front because the combustion ...

Aluminum cellular structures have been fabricated by combining a two-dimensional [0◦/90◦]2 arrangement of square Al 6061-T6 alloy tubes with orthogonal tubes inserted in the out-of-plane direction. By varying the tube wall thickness, the resulting three-dimensional cellular structures had relative densities between 11 and 43%. The dynamic compressive response of the three-dimensional cellular s...

This paper describes a simple technique for fabricating uniform arrays of metal and metal oxide nanotubes with controlled heights and diameters. The technique involves depositing material onto an anodized aluminum oxide (AAO) membrane template using a collimated electron beam evaporation source. The evaporating material enters the porous openings of the AAO membrane and deposits onto the walls ...
