The 1-phosphanorbornadiene-rhodium complex (Rh-PNBD) anchored on a mesostructured porous silica matrix is the first example of a rhodium center chelated by a phosphorus and an oxygen atom belonging to the anchoring siloxane moiety. These new hybrid silicas behave as very active recyclable hydrogenation catalysts, whic…

Sodium hexametaphosphate (HMP) stabilized nickel hexacyanoferrate (NiHCF) nanoparticles were prepared in aqueous solution and were successfully extracted into an organic phase using cetyltrimethylammonium bromide (CTAB) as the surfactant. Dynamic Light Scattering (DLS) studies suggest that the average size of the nano…

We obtained a high-luminance red phosphor by spray pyrolysis without postheating treatment using a high-temperature furnace with a long residence time and the addition of alkali metal salts to the precursor solution. The luminance under UV and vacuum UV radiation was about 100 and 90% that of the conventional phosphor…

A new approach to the design and control of shape memory alloy (SMA) actuators is presented. SMA wires are divided into many segments and their thermal states are controlled individually in a binary manner. The Peltier effect is used for heating and cooling individual segments of the SMA. Unlike the traditional way of…

This work describes how a new, extremely porous, hairy layer of carbon nano-fibers (CNFs) can be prepared on the surface of porous inorganic bodies, e.g. wash-coated monoliths. CNFs were prepared catalytically by methane and ethene decomposition over a Ni catalyst. The influence of the Ni particle size and growth cond…

The influence of small amounts (∼2 μg/cm 2 ) of deposited NaCl on the initial atmospheric corrosion of iron has been investigated in situ at varying relative humidities. The deliquescence of the NaCl crystallites and corrosion product formation was followed at relative humidities ⩾75% with quartz crystal microbalance…
