标 题:Bottom-Up, Scalable Synthesis Of Oxide-Based Sub-Nano And Nanofilaments And Nanofilament-Based Two-Dimensional Flakes And Mesoporous Powders

权利人:UNIV DREXEL
摘要:Provided are methods to convert—through a bottom-up approach—binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into lepidocrocitic nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

摘要:Polyazacrown polymers based on the azacrown monomer 1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosane (“H 6 Aza222â€?) are disclosed. Azacrown monomer units are preferably linked with a suitable linking agent, and the resulting polymers are can absorb mercury from a water stream and form a stable complex therewith. Methods of making and using the polyazacrown polymers are also disclosed. The polymers have a high absorption capacity for and selectivity towards mercury, which properties are useful for the remediation of mercury-contaminated water. The polymers can be regenerated by the efficient removal of the absorbed mercury. Further, the absorbed mercury that is liberated from the polyazacrown polymers can be effectively concentrated and captured to prevent its re-release into the environment.

标题:Synthesis of submicron grain metal carbides
发明人：MCCANDLISH LARRY E; SADANGI RAJENDRA K
权利人:NANODYNE INC
摘要:Submicron carbide particles are formed from metal containing precursor compositions where the metal is tantalum, niobium, vanadium or chromium by subjecting the precursor composition to a carbonization reaction. The carbonizing gas contains only hydrogen, nitrogen and carbon and the carbonizing reaction is conducted at a temperature of less than 1100° C. By maintaining the carbon deposition potential of the reaction at from 10% to 60%, the precursor composition can be reduced and carburized simultaneously to form the carbide. The formed product has a physical grain size less than 1 micron which significantly improves its ability to be milled with other compositions, as well as its use in cutting tools and the like.

摘要:This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands hasn a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.

摘要:The present invention relates to the method of manufacturing nano-sized metal carbide powders using self-propagating high-temperature synthesis. More particularly, the present provides a method for fabricating nano-sized metal carbide powders, comprising the steps of: (a) dry mixing process for mechanical mixing of metal oxide compounds, reducing agents, carbon source, carburization activators and particle growth inhibitors; (b) inducing process for self-propagating exothermic reaction accompanying reduction and carburization through heating a part of the mixture of the step (a) in the inert gas atmosphere; (c) crushing process for the reacted product of the step(b); and (d) washing and acid treatment process using distillated water and acid solution, respectively. Using the manufacturing method of the present invention, metal carbide powders having particle size below 100nm can be manufactured. In particular, this method has advantages of thermal efficiency, simple process and short processing time.
