摘要:Synthesize a nickel oxide-based oxidative dehydrogenation catalyst via a solvent-free process that comprises sequential steps a. mixing without added solvent a combination of a solid nickel precursor, a solid oxalate or oxalic acid and, optionally, a doping amount of a metal precursor for a period of time sufficient to convert the combination to a visually homogenous mixture; and b. calcining the visually homogeneous mixture at a temperature within a range of from greater than 250° C. to less than 800° C. for a time within a range of from 30 minutes to 360 minutes in an oxygen-containing atmosphere, preferably air, to form a calcined oxidative dehydrogenation catalyst. As a modification of the process, add an intermediate step between steps a. and b. to dry the homo geneous mixture at a temperature within a range of from 50° C. to 90° C. for a period of time within a range of from 10 minutes to 600 minutes to form a dried mixture. The resulting catalyst may be used in oxidative dehydrogenation of ethane.

摘要:The present invention relates to a production method of sol-gel ( 100 ) comprising tantalum metal and a method ( 200 ) concerning use of the sol-gel produced for enrichment of phosphopeptides by means of a microextraction syringe. The syringe which is filled with the sol-gel comprising tantalum metal enables to make analysis of natural samples, that comprise low amount of phosphoprotein, with high precision and in a very short time and it shows compliance with mass spectrometric techniques. Thus, it can be used for application of fast and practical analytical methods for the analysis made in phosphoproteomics studies wherein mass spectrometric techniques are used.

标 题 :Self-limiting thin film synthesis achieved by pulsed plasma-enhanced chemical vapor deposition
发明人：WOLDEN COLIN; SEMAN MICHAEL T
权利人:COLORADO SCHOOL OF MINES
摘要:Ta 2 O 5 and Al 2 O 3 thin films were fabricated by pulsed plasma-enhanced chemical vapor deposition (PECVD) with simultaneous delivery of O 2 and the metal precursor. By appropriately controlling the gas-phase environment self-limiting deposition at controllable rates (Ëœ1 â„«/pulse) was obtained. The process was insensitive to substrate temperature, with a constant deposition rate observed from 90-350° C. As-deposited Ta 2 O 5 films under these conditions displayed good dielectric properties. Performance improvements correlate strongly with film density and composition as measured by spectroscopic ellipsometry and Fourier transform infrared spectroscopy. Pulsed PECVD eliminates the need for gas actuation and inert purge steps required by atomic layer deposition.

标题 :Mesoporous transition metal oxide thin films and methods of making and uses thereof
发明人：BALKUS KENNETH J JR; KINSEL MARY E
权利人:UNIV TEXAS
摘要:Mesoporous transition metal oxide thin films and methods for producing these films are provided. Also provided are methods of fabricating useful chemical sensors and electrochromic devices from the thin films of the invention. Certain mesoporous transition metal oxide molecular sieves may be used as targets for pulsed laser ablation under controlled atmosphere, resulting in deposition of a thin film of the target material upon a substrate of choice. The thin films possess a mesoporous structure which may be enhanced by means of a hydrothermal treatment. The thin films also may be treated with a means of removing the templating agent used during synthesis of the mesoporous target material.
