Chance-Constrained Optimization for Treatment of Prostate and Other Cancers in Intensity-Modulated Proton Therapy
The quality of IMPT treatment plans may be drastically diminished by uncertainties such as proton range and patient setup errors. If these uncertainties are not figured into treatment planning, the dose distribution that the patient receives may not be the same as the planned dose distribution. New treatment plans, which include optimized software/programming,...

Organic Solar Cells Based on a Solution Phase Near-IR Absorbing Soluble Phthalocyanines
This invention is a solution-processed planar heterojunction (PHJ) organic photovoltaic (OPV) device based on a soluble titanyl phthalocyanine (TiOPc) derivative as the donor with photo activity extended up to 1 micron in the near-IR region of the solar spectrum, without significantly affecting the open-circuit photopotential (Voc). TiOPc is a metallated...

Peripheral and Non-Peripheral Substituted Phthalocyanines
This invention is directed to phthalocyanine chromophores with chalcogen based substituents on the peripheral and non-peripheral positions - phthalocyanine chromophores that have alkylthio (i.e., RS-) and alkoxy (i.e. RO-) on the peripheral (2,3,9,10,16,17,23,24) and nonperipheral (1,4,8,11,15,16,22,25) positions of the macrocyclic ring. Background: The...

Solution Processed Bulk Heterojunction Organic Solar Cells Based on Near-IR Absorbing Soluble Phthalocyanines
This invention demonstrates excellent near-IR photoactivity for solution-processed Bulk Heterojunction (BHJ) OPV device. For the optimized BHJ devices, the VOC is (a) higher than the corresponding solution processed Planar heterojunction (PHJ) device fabricated from octahexylthio-substituted C6-TiOPc and (b) comparable to the vacuum-deposited PHJ fabricated...

Soluble Titanyl Phthalocyanines with Enhanced Thin-Film Near-IR Absorptivity
This patented technology covers materials and methods for making Titanyl Phthalocyanines (TiOPc) and rendering them soluble using peripheral substituents. In addition, the method eliminates the need for a solvent in the synthesis step, and increases the purity of yield of the isolated materials. Furthermore, the organic molecules exhibit increased absorbance...
