| 20110045577 | Fabrication of conductive pathways, microcircuits and microstructures in microfluidic networks - Disclosed herein are a variety of microfluidic devices and solid, typically electrically conductive devices that can be formed using such devices as molds. In certain embodiments, the devices that are formed comprise conductive pathways formed by solidifying a liquid metal present in one or more microfluidic channels (such devices hereinafter referred to as “microsolidic” devices). In certain such devices, in which electrical connections can be formed and/or reformed between regions in a microfluidic structure; in some cases, the devices/circuits formed may be flexible and/or involve flexible electrical components. In certain embodiments, the solid metal wires/conductive pathways formed in microfluidic channel(s) may remain contained within the microfluidic structure. In certain such embodiments, the conductive pathways formed may be located in proximity to other microfluidic channel(s) of the structure that carry flowing fluid, such that the conductive pathway can create energy (e.g. electromagnetic and/or thermal energy) that interacts withy and/or affects the flowing fluid and/or a component contained therein or carried thereby. In other embodiments, a microsolidic structure may be removed from a microfluidic mold to form a stand-alone structure. In certain embodiments, the solid metal structures formed may interact with light energy incident upon a structure or may be used to fabricate a light-weight electrode. Another aspect of the invention relates to the formation of self-assembled structures that may comprise these electrically conductive pathways/connections. | 02-24-2011 |

| 20110192367 | ENGINE COMBUSTION CONTROL VIA FUEL REACTIVITY STRATIFICATION - A compression ignition engine uses two or more fuel charges having two or more reactivities to control the timing and duration of combustion. In a preferred implementation, a lower-reactivity fuel charge is injected or otherwise introduced into the combustion chamber, preferably sufficiently early that it becomes at least substantially homogeneously dispersed within the chamber before a subsequent injection is made. One or more subsequent injections of higher-reactivity fuel charges are then made, and these preferably distribute the higher-reactivity matter within the lower-reactivity chamber space such that combustion begins in the higher-reactivity regions, and with the lower-reactivity regions following thereafter. By appropriately choosing the reactivities of the charges, their relative amounts, and their timing, combustion can be tailored to achieve optimal power output (and thus fuel efficiency), at controlled temperatures (and thus controlled NOx), and with controlled equivalence ratios (and thus controlled soot). | 08-11-2011 |
