权利人:ASM IP HOLDING BV
摘要:Disclosed are methods and systems for forming a silicon-containing layer on a substrate. Further disclosed are composition and synthesis of silicon-containing precursor. The methods for forming a silicon-containing layer comprise executing a plurality of deposition cycles. A deposition cycle comprises a first precursor pulse that comprises exposing the substrate to a first precursor. The first precursor comprises a molecule comprising a P—Si bond. A deposition cycle further comprises a plasma pulse that comprises exposing the substrate to a plasma treatment. The plasma treatment comprises generating a plasma.

摘要:2,5-Dioxo-1,2-oxa-phospholanes of the formula (I) ##STR1## wherein R 1 is an organic radical and R 2 and R 3 each also represents an organic radical or hydrogen, are prepared by reacting 2-haloformylethyl-phosphinic acid halides of the formula (II) ##STR2## wherein R 1 , R 2 and R 3 are defined as in formula (I) and X means Cl or Br, preferably Cl, with an approximatey equimolar quantity of acrylic acid. The compounds (II) may also be produced in the reaction batch and in situ by reacting about equimolar quantities of a dihalophosphine of the formula (III) ##STR3## with an α,β-unsaturated acid (IV) n n R.sup.4 -- OH (IV) n n In the formulae (III) and (IV) R 1 , R 2 , R 3 and X are defined as indicated above. n In the reaction there is formed, in addition to the compounds (I), practically exclusively β-halopropionic acid and no free hydrogen halide. n The phospholanes (I) are valuable flame retarding agents for plastics, intermediates, for example, for the synthesis of biocidals etc.

摘要:The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO 2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.

标题 :Synthesis of polyazamacrocycles with more than one type of side-chain chelating groups
发明人：SHERRY A DEAN; WESTRENEN JEROEN VAN
权利人:UNIV TEXAS
摘要:The pH controlled selectivity of the sulfomethylation reaction is used to prepare a series of di-, tri-, tetra- and hexaazacyclomacrocycles with specified patterns of pendent side-chain chelating groups. The prepared mono and diacetic acid derivatives, together with monomethylenephosphonate and monomethylenephosphinate derivatives of [12]aneN4, [12]aneN3 and [9]aneN3, make these types of ligands easily available by a synthetic pathway that avoids the use of protective groups. The invention thus comprises a variety of compounds, methods and uses characterized by relatively high synthetic yields of polyazamacrocyclic ligands exhibiting a wide and predictable choice of metal ion binding constants water and lipid solubilities by reason of their substituent pendent groups.
