摘要:The invention relates to synthesis of nanoparticles from hazelnut husk extract by green synthesis with high efficiency. Use of chemical is limited in the present invention and therefore the synthesis of nanoparticles is provided by green chemistry in the present invention. Said hazelnut may be Corylus and said hazelnut husk may be cob or shell of the hazelnut. In an embodiment of the invention said Corylus may be Colyrus colurna, Corylus americana Corylus avellana, Corylus avellana var. Avellana, Corylus avellana var. Pontica, Corylus chinensis, Corylus colchica, Corylus × colurnoides, Corylus cornuta, Corylus cornuta ssp. californica, Corylus cornuta ssp. cornuta, Corylus fargesii, Corylus ferox, Corylus ferox var. ferox, Corylus ferox var. thibetica, Corylus heterophylla, Corylus heterophylla var. heterophylla, Corylus heterophylla var. sutchuensis, Corylus jacquemontii, Corylus maxima, Corylus potaninii, Corylus sieboldiana, Corylus sieboldiana var. mandshurica, Corylus sieboldiana var. sieboldiana, Corylus wangii, Corylus wulingensis or Corylus yunnanensis.

权利人:FERRO CORP
摘要:The present invention provides methods of controlling the properties of abrasive particles produced via hydrothermal synthesis for use in chemical-mechanical polishing slurries. In accordance with the methods of the invention, variables such as cerium salt concentration, dopant solution concentration, hydrothermal medium pH, hydrothermal temperature and processing duration are controlled to produce particles having the desired properties and shapes. The abrasive particles formed in accordance with the method of the invention can be used to produce CMP slurries that provide substantial improvements in the polishing of STI structures and a reduction in defects.

权利人:RHONE POULENC CHIMIE
摘要:The invention relates to new compositions based on ceric oxide having an improved oxygen storage capacity, these compositions being characterized in that they contain, besides ceric oxide, at least one oxide of another metallic element M chosen from the group consisting of iron, bismuth, nickel, tin and chromium or one of their mixtures, this oxide preferably being in solid solution with the abovementioned cerium oxide. The process of synthesis of these compositions consists in first of all preparing an intimate mixture between (i) a ceric oxide or a ceric hydroxide and (ii) at least one additive consisting of a hydroxide or a salt, thermally decomposable to an oxide, of the metallic element M, and in then calcining this mixture so as to obtain the desired composition based on oxides. The compositions according to the invention are particularly useful in the manufacture of catalysts and/or catalyst supports, especially those intended for treating exhaust gases from internal combustion engines.
