• Structuration of the CZA catalyst by washcoating was successfully obtained Inorganic colloids are crucial for obtaining good adherence on monolith Nevertheless, inorganic affect to catalytic properties Acidity like Al 2 O 3 and SiO is able dehydrate methanol DME CZA_10%Al formulation coated monoliths showed excellent activity performances. The best slurry prepare a structured synthesis reacti...

Hybrid polymer composites have become the interest of world, especially in mechanical and electronic applications. Recently, advanced machining techniques such as abrasive water jet hybrid been used to solve many problems including ability form complex shapes, high performance, better surface features, levels accuracy. In this study, effect ceramic particle (SiC Al2O3) constituents on propertie...

The use of slurry ice, both alone and in combination with ozone, as compared with traditional flake ice was investigated as a new refrigeration system for the storage of sardine (Sardina pilchardus). Microbiological, chemical and sensory analyses were carried out throughout a storage period of 22 days. According to sensory analyses, sardine specimens stored in ozonised slurry ice had a shelf li...

A study was undertaken on drained and undrained 1 ha grassland lysimeters to assess the effectiveness of multiple novel tracing techniques in understanding how agricultural slurry waste moves from land to water. Artificial fluorescent particles designed to mimic the size and density of organic slurry particles were found to move off the grassland via inter-flow (surface + lateral through-flow) ...

Excess crude protein (CP) in dairy cow diets is excreted mostly as urea nitrogen (N), which increases ammonia (NH) emissions from dairy farms and heightens human health and environmental concerns. Feeding less CP and more tannin to dairy cows may enhance feed N use and milk production, abate NH emissions, and conserve the fertilizer N value of manure. Lab-scale ventilated chambers were used to ...

NH3, CH4 and N2O emissions from dairy cattle and pig slurries were quantified. The effect of the following treatments was investigated: untreated covered slurry, mechanically separated slurry, anaerobically digested slurry, slurry covered with a layer of straw, and slurry aeration. Measurements were carried out with dairy cattle and with pig slurry, in winter and in summer. After storage, slurr...

Ceria-terbia solid solution nanobelts were prepared by an electrochemical route and tested as catalysts of high activity for CO oxidation.

Slurry, due to high microbiological contamination, requires hygienization before spreading. The agricultural usage of treated slurry has to guarantee biosafety. Therefore, constant monitoring of the slurry treatment process should be conducted. The use of Filter-Sandwich carriers seems to be a prospective solution. The aim of the research was to test whether Filter-Sandwich carriers influence t...

High-resolution electron microscopy was employed to characterize the interface structure of a cast Al-Mg-Si-Bi-Pb aluminium(6262)-based composite reinforced by alpha alumina particles with a trace of beta alumina in order to investigate the behaviour of alloying elements in cast composites. Except for a few primary Mg2Si particles, few reaction products were detected at the interface of Al/alph...

Using atomic force microcopy, mechanochemical removal behaviors of GaAs surface slid by Al2O3, SiO2, and CeO2 micro-spherical tips were investigated in ambient environment. High-resolution transmission electron microscope characterization demonstrates that defect-free material was achieved on under the contact pressures much below yield limit plastic deformation, which can be ascribed to water-...
