Abstract: A system for logistics management based on odor molecules is provided. The system includes a sensor, an information device and a server. The sensor is arranged on an item to be tracked, and includes a colorimetric sensor array and a material which stores and releases molecules, wherein the material releases an odor molecule. The colorimetric sensor array includes a plurality of sensing materials. The plurality of sensing materials reacts with at least one metabolic molecule of the odor molecule to enable the colorimetric sensor array to present a color pattern. The information processing device includes an image capturing element for obtaining the color pattern and a transceiver for transmitting the color pattern. The server stores a database. The color pattern and the database are compared to generate a comparison result.

Abstract: A method of using high push force to fabricate a composite material containing carbon material comprises steps placing a substrate in a carbon material-containing dispersion including a carbon material, and letting one surface of the substrate contact the carbon material-containing dispersion; and providing a high push force range between 300 G and 3000 G to the carbon material-containing dispersion to push the carbon material-containing dispersion and make the carbon material enter the substrate to form a composite material containing the carbon material.

Abstract: A method for fabricating a catalytic 3-dimensional network material comprises steps: mixing an aqueous solvent with a nitrogen-containing carbon material whose surface is doped with nitrogen atoms to form a first dispersion liquid, and mixing the first dispersion liquid with ammonium carboxymethyl cellulose to form a first gel; undertaking a freeze-drying process of the first gel to remove water from the first gel to form a first product; and undertaking a low-temperature heating process of the first product at a temperature of 50-380° C. to cure the first product into a 3D network material doped with nitrogen atoms. The catalytic 3D network material of the present invention has a very high specific surface area to increase the catalytic efficiency.
