Design of a reconfigurable liquid hydrogen fuel tank for use in the Genii unmanned aerial vehicle
(Transactions of the Cryogenic Engineering Conference–CEC: Advances in Cryogenic Engineering, 2014)
Long endurance flight, on the order of days, is a leading flight performance characteristic for Unmanned Aerial Vehicles (UAVs). Liquid hydrogen (LH2) is well suited to providing multi-day flight times with a specific ...
Anisotropic buckypaper through shear-induced mechanical alignment of carbon nanotubes in water
A simple method for aligning nanotubes in buckypaper with a modified Taylor–Couette system is reported. Using shear forces produced by a rotating cylinder to orient multi-walled carbon nanotubes in a surfactant-assisted ...
Bio-renewable precursor fibers from lignin/polylactide blends for conversion to carbon fibers
Lignin, a highly aromatic biopolymer extracted as a coproduct of wood pulping, was investigated as a suitable precursor for carbon fibers. Lignin was chemically modified and blended with poly(lactic acid) (PLA) biopolymer ...
A New Variable Temperature Solution-Solid Interface Scanning Tunneling Microscope
Scanning tunneling microscopy (STM) has been widely used to investigate surface structures and electronic properties of adsorbed species on surfaces and also for observing chemical reactions on surfaces. The technique can ...
