标 题:Fabrication of free standing membranes and use thereof for synthesis of nanoparticle patterns
发明人：YANG JUN; LI TINGJIE
权利人:YANG JUN; LI TINGJIE; UNIV WESTERN ONTARIO
摘要:The present disclosure discloses a method of fabrication of free standing open pore membranes with uniform pore size and shape and ordered pore distribution, and its use for synthesis of nanoparticle patterns. The method includes applying a photoresist layer to the top surface of a substrate, heating the photoresist layer for a period of time, and exposing the photoresist layer to a dose of ultraviolet radiation through a mask having a predetermined pattern. The dose of ultraviolet radiation is controlled in intensity and time and the photoresist layer is exposed such that a top portion of the photoresist layer through which the dose of ultraviolet radiation enters the photoresist layer undergoes greater cross linking than a bottom portion of the photoresist layer immediately adjacent to the top surface of the substrate such that a cross linking gradient develops through a thickness of the photoresist layer. The mask is removed and the membrane is readily detached from the top surface of the substrate since the portion of the membrane adjacent to the top surface is less cross linked than the top surface of the membrane. The detached membrane forms a free standing patterned membrane having a preselected pattern of open pores. The method can be used with positive photoresist materials as well when deposited on a UV transparent substrate so that the photoresist can be exposed to UV from its top with photomask and UV exposure from its back of the transparent substrate without the photomask.

标 题 :Synthesis of monofunctional thiuram accelerator
发明人：SPILKER THOMAS FRANKLIN; Jin ji yang; FEHER FRANK J
权利人:GOODYEAR TIRE & RUBBER
摘要:The present invention provides a route for synthesizing monofunctional thiuram compounds that is safe, environmentally friendly, and cost effective. This method specifically involves synthesizing a monofunctional thiuram by (1) reacting a tetraorganylthiuram disulfide with an organyl mercaptan to produce the monofunctional thiuram and a dithiocarbamate metal salt or a dithiocarbamate metalloid salt under basic conditions, (2) separating the monofunctional thiuram in an organic phase from the dithiocarbamate metal salt or the dithiocarbamate metalloid salt in an aqueous phase, and (3) recovering the monofunctional thiuram from the aqueous phase. The monofunctional thiuram compounds made in accordance with this invention are of particular value as accelerators for use in the vulcanization of rubber. The use of these monofunctional thiuram compounds as accelerators provides good cure rates and as well as good scorch safety.

摘要:A polymer for use in photoresist compositions is synthesized by effecting polymerization reaction to form a polymerization product mixture and subjecting the mixture to molecular weight fractionation by a liquid phase separation technique using a good solvent and a poor solvent. The fractionation step is iterated at least twice, and one iteration of fractionation includes adding a good solvent which is different from the good solvent added in the other iteration of fractionation.
