An important variation in the thermal conductivity of porous alumina membranes has been observed from RT up to 1300 °C. This is due to the water loss at low temperatures or phase transitions at higher temperatures.

This study aims to develop a long-acting and implantable drug release device that can well control the release rate and concentration of the loaded drug. The proposed long-acting and implantable drug release device consists of a tubular nanoporous anodic aluminum oxide (AAO) and the microporous chitosan/collagen composite encapsulated inside it. The nanopore size of the AAO tube can be arranged by the anodization parameters to adjust the release rate and concentration, while the microporous chitosan/collagen composite can provide the device with a long-acting release property. Fabrication results indicated that the AAO tube has a uniform pore arrangement with pore size around 50 nm. And the synthesized microporous chitosan/collagen composites composites containing 90% of chitosan had the highest moisture content; therefore were used as the drug carriers. Release experiments demonstrate that the proposed long-acting drug release device had released only less than 60% of the loading drug at the 16th release day.

In this study, a simple, rapid and inexpensive approach for the screening of heavy metals with photometric reagents was developed based on porous, anodic aluminium oxide (AAO) films, with detection limits of 0.45 mg L−1 (Co2+), 0.25 mg L−1 (Pb2+) and 0.59 mg L−1 (Ni2+).
