Abstract: A nonwoven laminate is provided having multi-purposes. One embodiment is an A-layer having a high surface tension factor to prevent water absorption and can be used for fender liners or underbody surfaces of motor vehicles to prevent water from absorbing into the material as well as ice accumulation. The water resistant properties are the result of utilizing a newly engineered hydrophobic PET (H-PET) fiber. Another embodiment, useable alone or in combination with the A-layer is a B-layer that has hollow multi-lobe cross-sectional fibers to provide enhanced sound absorption properties. One or both layers have thermo-moldable characteristics that allow them to be shaped into a specific geometry. In this case, the low melt fibers provided in one or both layers are “fused” and interlock or bridge together to yield a rigid nonwoven water/ice resistant and/or sound absorbing composite.

Abstract: The present development is a metal particle coated nanowire catalyst for use in the hydrodesulfurization of fuels and a process for the production of the catalyst. The catalyst comprises titanium(IV) oxide nanowires wherein the nanowires are produced by exposure of a TiO2—KOH paste to microwave radiation. Metal particles selected from the group consisting of molybdenum, nickel, cobalt, tungsten, or a combination thereof, are impregnated on the metal oxide nanowire surface. The metal impregnated nanowires are sulfided to produce catalytically-active metal particles on the surface of the nanowires The catalysts of the present invention are intended for use in the removal of thiophenic sulfur from liquid fuels through a hydrodesulfurization (HDS) process in a fixed bed reactor. The presence of nanowires improves the HDS activity and reduces the sintering effect, therefore, the sulfur removal efficiency increases.

Abstract: Provided are methods of trimming photoresist patterns. The methods involve coating a photoresist trimming composition over a photoresist pattern, wherein the trimming composition includes a matrix polymer, a free acid having fluorine substitution and a solvent, the trimming composition being free of cross-linking agents. The coated semiconductor substrate is heated to cause a change in polarity of the resist polymer in a surface region of the photoresist pattern. The photoresist pattern is contacted with a developing solution to remove the surface region of the photoresist pattern. The methods find particular applicability in the formation of very fine lithographic features in the manufacture of semiconductor devices.
Abstract: The invention relates to new polymers that comprise units that contain one or more photoacid generator groups and photoresists that contain the polymers. Preferred polymers of the invention are suitable for use in photoresists imaged at short wavelengths such as sub-250 nm or sub-200 nm, particularly 248 nm and 193 nm.
Abstract: A barrel plating or high-speed rotary plating method for electronic components, and a neutral tin plating solution used therein. A plating solution that includes (A) stannous ions, (B) an acid or a salt, (C) a complexing agent, and (D) a diamine that has a polyoxyalkylene chain, and that has a pH in a range between 4 and 8 is used. The use of this neutral tin plating solution prevents the electronic components from coupling together during the barrel plating, enabling an improvement in manufacturability in barrel plating.

Abstract: Shielding coatings are applied to polymer substrates for selective metallization of the substrates. The shielding coatings include a primer component and a hydrophobic top coat. The primer is first applied to the polymer substrate followed by application of the top coat component. The shielding coating is then selectively etched to form an outline of a desired current pattern. A catalyst is applied to the patterned polymer substrate followed by electroless metal plating in the etched portions. The portions of the polymer substrate which contain the shielding coating inhibit electroless metal plating. The primers contain polyamines and the top coat contains hydrophobic alky organic compounds.
