Patent number: 11776705Abstract: A method of providing alpha particle emitters and materials suitable for use in generating the alpha particles for medical treatment is disclosed. Metal oxide targets, preferentially Bi2O3 pellets and Bi2O3 coatings on metallic or metal oxide substrates are formed. The targets placed in a heated vacuum chamber subjecting to irradiation using a 6Li beam at an elevated temperature below the melting point of the target generate a radioactive gas, such as 211Rn, the radioactive gas is carried by an inert gas which is delivered a carrier for, such as a carbon column or oil for delivery to a treatment facility. The radioactive gas such as 211Rn generates 211At, which has a useable half-life of at least about 14 hours, in turn releases alpha particles which are effective for use in medical procedures.Type: GrantFiled: January 16, 2021Date of Patent: October 3, 2023Assignee: INNOSENSE LLCInventors: Uma Sampathkumaran, Raymond Winter, Harini Madakashira

Patent number: 11760888Abstract: Materials are disclosed for the safe sequestration and removal of hazardous contaminants from a surface. The materials can be sprayed, rolled, painted, brushed or dip coated onto any surface and allowed to dry and/or cure at room temperature or drying/curing can be accelerated by the application of heat to form a coating that entraps the contaminant therein. The coating and the entrapped contaminant can then peeled from the surface and safely disposed of to minimize hazardous waste. The coating includes a colorimetric additive that is specific to the contaminant, the coating and the contaminant producing a visual indication of contamination.Type: GrantFiled: May 28, 2021Date of Patent: September 19, 2023Assignee: INNOSENSE LLCInventors: Uma Sampathkumaran, Kevin H.

Patent number: 10435584Abstract: The present invention relates to hydrophilic anti-fog coatings. In particular, the coatings use two types of nanoscale particles, colloidal silica and porous organosilicate micelles, in a polyurethane matrix. The invention is an anti-fog coating for optically clear substrates (polycarbonate, polyurethane, nylon, polyester and other clear plastics) without the need for a primer and glass substrates with an additional primer layer, comprising monosized colloidal silica nanoparticles and porous organosilicate micelles in a polyurethane matrix. The silica is preferably 1-5% by weight and the micelles are loaded at 0.1 to 10% volume percentage by volume. The polyurethane prepolymer is dissolved at 10-40% by weight in a mixture of tertiary amyl alcohol and diacetone alcohol to customize for dip, flow or spray coating processes.Type: GrantFiled: December 11, 2017Date of Patent: October 8, 2019Assignee: INNOSENSE LLCInventors: Uma Sampathkumaran, Kevin H.

Patent number: 9896772Abstract: The present invention relates to a modular chemiresistive sensor. In particular, a modular chemiresistive sensor for hypergolic fuel and oxidizer leak detection, carbon dioxide monitoring and detection of disease biomarkers. The sensor preferably has two gold or platinum electrodes mounted on a silicon substrate where the electrodes are connected to a power source and are separated by a gap of 0.5 to 4.0 ?M. A polymer nanowire or carbon nanotube spans the gap between the electrodes and connects the electrodes electrically. The electrodes are further connected to a circuit board having a processor and data storage, where the processor can measure current and voltage values between the electrodes and compare the current and voltage values with current and voltage values stored in the data storage and assigned to particular concentrations of a pre-determined substance such as those listed above or a variety of other substances.Type: GrantFiled: March 13, 2015Date of Patent: February 20, 2018Assignee: INNOSENSE LLCInventors: Maksudul M.

Publication number: 20150168225Abstract: The present disclosure relates to a dosimeter for measuring exposure to heat over time in combination with peak temperature indicators and reversible temperature indicators. The preferred temperature indicator tag is credit card sized and comprises four time-temperature dosimeters. Each dosimeter has a wick in contact with a separate reservoir containing a mix of a colored dye, a wax and an amorphous polymer to indicate a distinct temperature range when the mix melts. The wicks are preferably made of porous paper with a pore size around 8 microns to allow for proper capillary action along its length. An adhesive, except where each wick contacts its respective reservoir and at a vent, preferably seals each wick. The tag preferably has a plurality of peak temperature indicators where each indicator has a blend of a dye, a wax and a polymer for a temperature indication range. The tag also preferably has a plurality of reversible temperature sensors.Type: ApplicationFiled: February 5, 2015Publication date: June 18, 2015Applicant: INNOSENSE, LLCInventors: Corey M.
