Reduction of Magnetite by Copper Matte (2nd Report)

Nitrite reduction by copper complexes.

A series of copper complexes have been synthesised as potential agents for the catalytic reduction of nitrite anions. The ligands and corresponding copper complexes have been characterised by using a range of techniques including X-ray crystallography, NMR, microanalysis, mass spectrometry, infra-red spectroscopy, electrochemical studies and density functional theory calculations. For complexes...

Visualization of IDS data by HeiankyoView: 2nd report

IDS (Intrusion Detection System) is an active research topic for the purpose of cost reduction of security maintenance of computer network. However, existing IDS technologies still have some issues, including enormous log output data, and lack of analysis technologies of complicated behavior of recent intrusions. We proposed a visualization of IDS data, which constructs hierarchical data accord...

Visual Appearance of Matte

All visual sensors, biological and arti cial, are nite in resolution by necessity. This causes the e ective re ectance of surfaces in a scene to vary with magni cation. A reectance model for matte surfaces is described that captures the e ect of macroscopic surface undulations on image brightness. The model takes into account complex physical phenomena such as masking, shadowing and interre ect...

Adsorption of copper ion on magnetite-immobilised chitin.

The adsorption of Cu2+ from aqueous solution by magnetite-immobilised chitin (MC) was studied in batch mode. Two conventional adsorbents, cation exchange resin (CER) and activated carbon (AC) were used for the comparison. The physicochemical parameters including pH, concentration of adsorbent, temperature and initial Cu2+ concentration were optimised. Under the optimised conditions, the removal...
