The content of metal ions and their valence state for three Ni x Cu y Mn 3-x-y BO 5 compositions were estimated by EXAFS XANES spectroscopy methods. In all compositions, the copper did not exceed 0.25; in third composition, some manganese entered compound only trivalent, but also divalent state. A detailed study magnetic properties showed that two transitions are observed compositions: one regi...

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...

This study reveals the influence of different TiO 2 supports on catalytic performance and phase transformations Co 3 O 4 during CO-PrOx.

A microwave photonic channelizer can achieve instantaneous reception of ultra-wideband signals and effectively avoid electronic bottleneck; therefore, it be perfectly applied to a wideband radar system warfare. In channelization schemes based on an optical frequency comb (OFC), the number lines usually depends that sub-channels. order improve utilization rate OFC, we propose scheme shift OFC by...

Ethylene glycol bisthioglycolate modified gold nanoparticles grafted Mn doped Fe3O4 nanoparticles (Au@Mn-Fe3O4 NPs) adsorbent was synthesized and applied for extraction and preconcentration of trace amounts of Ag+ and Pb2+ ions in artificial and natural saliva. The adsorbent was characterized by transmission electron microscopy (...
