Publication number: 20080102386Abstract: The present invention provides compositions, devices and methods related to the alignment of materials including polymers. In some cases, the present invention comprises the assembly of molecules (e.g., polymers) via intermolecular interactions to produce extended networks, which may have enhanced properties relative to the individual molecules. Such networks may be advantageous for use in electronics, photovoltaics, sensor applications, and the like. In some embodiments, the present invention may enhance the performance of certain optical devices, such as liquid crystal displays (e.g., color liquid crystal displays) by providing enhanced contrast ratio, faster response times, and/or lower operating voltage.Type: ApplicationFiled: December 18, 2006Publication date: May 1, 2008Applicant: Massachusetts Institute of TechnologyInventors: Timothy M.

Publication number: 20020169221Abstract: The disclosed process to obtain a modifier for cement systems comprises a synthesis of the modifier by a process of polymerization in a soft alkaline catalysis. This contributes to the formation of a product with a low molecular mass and viscosity. The concentration of the homogeneous aqueous solution is from 40-58% and the specific production of the process is Q=0.25 to 3.00 kg per hour in comparison with the specific production of the known prototype which is Q=0.03 to 0.04 kg per hour. One of the most important characteristics of the new process used to obtain the disclosed modifier is the fact that synthesis is achieved without external heat sources. Also, synthesis is achieved either by a periodic process or a continuous process.Type: ApplicationFiled: February 18, 2002Publication date: November 14, 2002Inventor: Jaime Moreno
