Fabrication of Lotus-Type Porous Aluminum Utilizing Decomposition of Moisture
Lotus-type porous aluminum with cylindrical pores oriented in one direction was fabricated by a casting method utilizing the decomposition of moisture in a vacuum. Hydrogen decomposed from moisture is utilized for cylindrical pores to grow during unidirectional solidification. However, pores are not formed in the case of a casting in hydrogen or argon atmosphere, because hydrogen or argon gas p...
متن کاملEffect of Hydrogen Pressure on Moisture-Based Fabrication of Lotus-Type Porous Nickel
Lotus-type porous nickel, which has long straight pores aligned in one direction, was fabricated by utilizing moisture during unidirectional solidification in argon atmosphere. We studied the effect of the quantity of hydrogen in the atmosphere on the fabrication of lotus-type porous nickel. Adding hydrogen in the atmosphere, it was expected that the porosity of the lotus-type porous nickel wit...

Fabrication and characterization of boron-related nanowires
A thermal vapor transport process has been employed for fabrication of boron-related (boron, boron–silicon alloys, and MgB2) nanowire films on Au-coated Si and MgO substrates. Tangled polycrystalline as well as aligned single-crystalline boron nanowires (BNWs) have been obtained and their growth mechanism investigated at different growth temperatures, cooling rates, and vapor sources. The growt...
