Abstract RFID technology is the popular technology in recent years and applies to many automatic identification applications such as supply chain management, thief-prevention and so on. Supply chain system with the help of RFID system reduces the cost in business operation. Different members in the supply chain connect to the same RFID tag for acquiring their own data. Members can protect …
Abstract. The selective hydrogenation of nitrobenzene (NB) over Ni/y-Al2O3 catalysts was investigated using different media of dense phase CO2, ethanol, and n-hexane. In dense phase CO2, the total rate of NB hydrogenation was larger than that in organic solvents under similar reaction conditions; the selectivity to the desired product, aniline, was almost 100% over the whole conversion rang…
We present an endogenous growth model in which both the investmetit to develop a new technology—that upgrades the quality of machines—and entry of imitators are determined endogenously. According to the model, how soon the new-technology machine is launched after the patent is granted is influenced by two factors: returns to scale in technology development and "strategic delays." Strategic …
Abstract. In order to develop a catalyst with high activity and stability for catalytic wet air oxidation of pollutant dyes at room condition, a new polyoxometalate Zn1.5PMo12O40 with nanotube structure was prepared using biological template. The structure and morphology were characterized using infrared (IR) spectra, UV–vis diffuse reflectance spectra (DR-UV–vis), elemental analyses, X…
