标题 :Rapid synthesis of titanate nanomaterials
发明人：KUNDU ANIMESH
权利人:UNIV LEHIGH
摘要:Provided herein is a hydrothermal process for the rapid synthesis of inorganic nanomaterials (e.g., nanofibers) containing sodium, bismuth, titanium, and oxygen, as well as new compositions made thereby. The process involves heating an aqueous solution or suspension of suitable salts of aforementioned elements at elevated temperature and pressure under constant stirring in a hermetically sealed vessel for a predetermined amount of time (e.g., less than two hours). The powder thus obtained contains nanofibers of rectangular cross-section, with the smallest fibers typically have a cross section of 16 nm×40 nm. Example fibers made by such processes have an aspect ratio exceeding 200.

摘要:Bulk nanostructured alloys, such as aluminum 5083 alloys reinforced with 10 wt. % particulate B 4 C, was synthesized by cryomilling and spark plasma sintering. Material for the alloy are selected and the selected raw materials are cryomilled, mechanical milling at cryogenic temperatures, to fabricate nanostructured alloys at low temperatures. The cryomilled powders are then degassed, and consolidated using spark plasma sintering into dense bulk materials. The material thus obtained achieved near full density bulk materials, while retaining the nanocrystalline nature. The densities of the compacts were measured using Archimedes method. XRD, SEM, TEM, and hardness testing were used to characterize the cryomilled powders and consolidated compacts.

权利人:SAUDI BASIC IND CORP
摘要:The present invention is for a process for making a heteropoly acid compound catalyst for oxidation of unsaturated aldehydes, such as methacrolein, to unsaturated carboxylic acids, such as methacrylic acid, said catalyst containing oxides of molybdenum, phosphorus, and M′, wherein M′ is cesium, potassium, rubidium, or sodium, and bismuth. The process is a synthesis of the catalyst with specific process conditions for addition of the bismuth compound as an aqueous slurry without nitric acid. A catalyst precursor is formed by removing the water and drying the solid particles. The heteropoly acid compound catalyst is formed by calcination of the catalyst precursor.
