A rapid response relative humidity sensor based on nano-structured aluminum oxide thin film is disclosed. The main body of the sensor is an anodic aluminum oxide thin film of about 2-20 &#x3bc;m thick formed from an Al substrate which serves as one electrode. A porous metal layer of about 20-200 nm thick is formed over the anodic aluminum oxide thin film and functions as a second electrode. The alumina thin film contains nano-sized channels of about 10-100 nm in diameter, serving as a capacitive relative humidity sensor having high sensitivity and short response time. Thermal annealing at elevated temperature improves the linearity of the capacitance versus humidity curve, giving a full range humidity sensing range. Hysteresis and degradation are negligible for the humidity sensors.

Methods of producing carbon nanostructures utilizing a polymer and a nanostructure template to form carbon nanostructures are disclosed. The method does not require a metal catalyst.

Methods for producing carbon nanostructures

A technique has been developed to fabricate micro- or nanopumps based on porous alumina thin films. The main body of the nanopump consists of a porous alumina thin film (containing nano-sized channels of about 40-300 nm in diameter) with conductive surfaces (e.g. Au coating layers) on both sides of the film. Through the fabrication of nanochannels in (the alumina films) and the subsequent annealing and surface activation processes, high-efficiency micro- or nanopumps can be made. The nanofluidic flow through the nanochannels of the alumina thin films is driven by an electric field with no moving parts. The flow rate (up to 50 millilitres/(min&#xb7;cm)) of water through the alumina thin film can be continuously tuned through the intensity of the electric field, i.e., the DC electric potential applied across the nanochannels.

A lithium ion battery is disclosed in which the negative electrode material comprises carbon nanostructures having no dimension greater than 2 &#x3bc;m. The battery has a high reversible capacity of the order of 400 mAh/g to 500 mAh/g which can be maintained over a long cycle-life (at least 30 cycles). The carbon nanostructures may be mixed with graphite to improve conductivity. The carbon nanostructues may be synthesized using an AFI template material followed by calcination.
