摘要:
A novel method for fabricating polymer, e.g., polydimethylsiloxane (PDMS),-coated dip-pen nanolithographic (DPN) stamp tips. This kind of tip adsorbed chemicals (“inks”) easily and was used to generate DPN nanopatterns which were imaged with the same tip after DPN process. This method built a bridge between micro-contact printing (μCP) and DPN, making it possible for one to easily generate smaller structures of any molecules which have been patterned by the μCP technique. The easy tip-coating and writing process enriches the state-of-the-art DPN technique. The sub-100 nm DPN resolution obtained by using this kind of novel tip is comparable to that with a conventional Si3N4 probe tip. Importantly, the unique stamp tip was able to transfer solvent (e.g., liquid “ink”) onto a substrate, resulting in fabrication of hollow nanostructures with only one DPN holding/writing step. Inks comprising metals and sol-gel materials are noted, as well as applications in photomask repair, enhancement, and fabrication.

摘要:
A new, low temperature method for directly writing conductive metal traces with micron and sub-micron sized features. In this method, a flat beam is used, such as an AFM cantilever, with or without a tip, to draw traces of metal precursor ink onto a substrate. The dimensions of the metal traces can be directly controlled by the geometry of the cantilever, so that one can controllably deposit traces from 1 micron to over 100 microns wide with microfabricated cantilevers. Cantilevers with sharp tips can be used to further shrink the minimum features sizes to sub-micron scale. The height of the features can be increased by building layers of similar or different material. To obtain highly conductive and robust patterns with this deposition method, two general ink formulation strategies were designed. The key component of both ink systems is nanoparticles with diameters less than 100 nm. Because nanoparticles typically have significantly lower melting points than the bulk material, one can fuse, sinter, or coalesce collections of discrete particles into continuous (poly)crystalline films at very low temperatures (less than about 300° C., and as low as about 120° C.). In the first strategy, one can disperse hydrocarbon-capped nanoparticles in a suitable solvent, deposit them on a surface in the form of a pattern, and then anneal the film by heating to form continuous metallic patterns. In the second strategy, one can deliver metal compounds to the surface in the presence of a reducing matrix and then form nanoparticles in situ by heating that subsequently coalesce to form continuous metallic patterns. In studies with platinum and gold inks, both nanoparticle-based methods yield micron sized traces on glass and oxidized silicon that have low resistivity (4 microohm·cm), and excellent adhesion properties.

The invention relates to a method for rapidly, efficiently heating and dispensing a flowable food product, using a device preferably of limited footprint whereby removable cassettes are provided for receiving a food-containing package. The cassettes at least include a direct conduction surface and an insulating coverage that substantially reduces radiant heat loss outside the cassettes. Preferably, there is provided peristaltic pumps, each one being adapted to engage a discharge tube of the food pouch wherein the pumps have their rotor plane oriented in alignment or parallel to the axial plane of the cassettes. Cassettes are heated by low power density generating heating members, such as a thin film heater or equivalent.

A merchandiser system and method for thawing, displaying, and warming previously baked dough products, such as cookies, under controlled drying conditions, including a warming compartment and a merchandiser. The merchandiser controls the drying of moisture in the thawed, baked products to maintain the organoleptic and/or texture properties of the products at essentially the same level as those of freshly baked products for a period of at least about 2 hours.
