Aerosol Device
The present invention provides the method for highly effective volumetric decontamination allowing to killing on a contact airborne and surface adsorbed bio agents. The method employs two elements, proprietary pneumatic aerosol (fog) generator VAG-2 and electrochemically-activated solutions (EAS). The method was evaluated and shown highly effective for irreversible decontamination of vegetative microbial cells, spores and viruses in test chamber of ~100 ft3 and a room of ~3000 ft3. The electrochemical activation technology is based on producing of meta-stable (activated) solutions with anomalous physicochemical and catalytic reactivity for their further use in various technological processes in place of traditionally applied aggressive chemicals. Usual source solutions for electrochemical activation processes are sodium chloride aqueous solutions with the concentration < 5.0 g/L. EAS bactericidal effectiveness was previously published and demonstrated in different applications, however all applications employed EAS only as washing /decontaminating agent. Present Invention relates to application of EAS as aerosol (fog). The term aerosol, aerosol fog, or fog as the terms are used herein refer to an air-suspended liquid having micro-particle droplets of characteristic cross section and/or size comprising electrochemically-active agents with sufficiently large surface areas whereby probability of contact with bio agents in a process area is high. EAS is produced with commercially available device STEL (FEM-3 flow electrochemical module element; US Pat 5,635,040). EAS is atomized with VAG-2 atomizer, which is the part of the invention. Pneumatic Vortical Aerosol Generator – VAG- 2 is original atomizer allowing for the production of the aerosol particles with the size from 7 to 16 µ at the rate from 5 to 300 ml/min correspondingly, with the possibility to control the required particle size. EAS aerosol has significant advantageous over EAS, allowing for simultaneous decontamination of airborne and surface-adsorbed bio agents with EAS minimal volume and practically no wastes produced. Experimental data indicate that EAS aerosol has very low corrosiveness, possess no negative effect to sensitive equipment and does not destroy the surface of different tested materials. Limited toxicity tests were conducted with mice directly exposed to EAS aerosol; no acute and short-term toxicity was revealed.

METHODS AND SYSTEMS FOR INTEGRATING ION MANIPULATION DEVICES
Different ion mobility (IM) separation techniques offer capabilities that are unique in one aspect. For example, collision cross sections (CCS) can be directly calculated from drift time measurements in a constant field IM platforms. Oscillatory field IM (such as traveling wave IM) has low voltage requirements but calculating CCS cannot directly obtained from drift time measurements and require calibration against compounds of known CCS measured in another constant field IM device. Traveling wave-based IM instruments can achieve extremely high resolution but accurate CCS require measurements in a different device. Therefore, it is beneficial to have one instrument that combine constant and oscillatory field IM. We disclose an array of embodiments for a device that seamlessly and efficiently perform constant field IM and oscillatory field IM.
PRODUCTION AND STORAGE OF METAL OXIDE OBJECTS HAVING A METALLIC COATING (iEdison No. 0685901-22-0019)
We propose microsphere infusion and microsphere coating as two augmentations of traditional sol-gel microsphere processing as a way to reduce the radiation hazards for several potential applications areas. First, we propose to infuse inert metal oxide microspheres (such as alumina) with either target materials (for subsequent irradiation and transmutation of the loaded species) or desired radioactive species. This approach can be desirable in different applications for several reasons including (1) allowing for sol-gel production equipment and processing steps to take place in a non-radiological environment (as opposed to performing sol-gel using a feed solution that contains the radioactive species and requires radiological operations), (2) decreasing the releasability of the radioactive species from the matrix material in the event of exposure to the environment, (3) providing a low-z matrix for beta radiation emission absorption, decreasing bremsstrahlung production, and (4) enabling the incorporation of heat-producing species into a more thermally conductive, yet refractory, matrix material than a pure metal oxide of that heat-producing isotope. Second, we propose to use a coating technology, such as electroless autocatalytic deposition of metals, to apply a coating around the outside layer of microspheres. This approach can be desirable in different applications for several reasons including (1) increasing the thermal conductivity of a packed assembly of heat-producing microspheres, lowering the thermal gradient, (2) improving the retention of the metal oxide microsphere material and any sorbed species, decreasing the releasability in the event of exposure to the environment, and (3) reducing the generation of dust from microspheres subjected to vibrations or impact that would otherwise cause the generation of small metal oxide fines.
METHOD FOR PURIFICATION AND REMOVAL OF POTASSIUM FROM NONPOLAR AND SURFACTANT SOLUTIONS AND MIXTURES
The invention uses high surface area, fine inorganic particulates (e.g., magnesium silicate) for the chemical adsorption and extraction of metal ions, like potassium, from neat nonpolar and detergent liquids and mixtures. The particular novelty of this invention is in the application: using such materials in the purification of trace radioactive potassium (40K) from liquid scintillation cocktails and components, which has been demonstrated in our lab. This novel invention allows for lower background cocktails to be created for more sensitive analytical measurements. It is easy to implement and effective on cocktails and the neat reagents that make up the cocktails. More conventional purification methods (e.g., distillation, liquid-liquid extraction, etc.) are much less straightforward and/or not possible, particularly on the finished cocktail products. This same technology has been implemented at industrial scales for other applications.

BIOSEQUENCE-BASED APPROACH TO ANALYZING BINARIES
In a dynamic computing environment, it is a nontrivial task to verify code running in the environment because most approaches to software similarity require extensive and time-consuming analysis of a binary, or the approaches fail to recognize executables that are similar but nonidentical. A biosequence-based method for quantifying similarity of executable binaries is used to identify allowed codes in a real-world multi-user environment.
APPARATUSES AND METHODS FOR PERFORMING MULTIPLE OMICS ANALYSIS AND PROCESSING ANALYTE MIXTURES (iEdison No. 0685901-21-0013)
In this invention disclosure, we described a nanoscale sample preparation method and device to enable the parallel analysis of many different types of molecules in small amounts of biological samples, down to single cells. The main innovations are: 1. We developed a nanoliter dividing technology to parallelly splitting samples between two droplet arrays, which will be measured separately with different technology. 2. The technology involves two key steps: (1) merge of two droplet arrays to mix; (2) split the two droplet arrays to generate two chips for subsequent analysis. The overall workflow is shown in Figure 1. Single cells or a low number of cells are isolated into nanodroplets, followed by cell lysis to release intracellular molecules, such as RNA transcripts, proteins, and metabomics. At the same time, we load an array of blank droplets on a different chip. Next, we will align the two chips together to allow one-to-one droplet merging (figure 2). The assembled droplet chips will be incubated to allow efficient mixing between droplet pairs. Finally, the two chips are separated to split the merged droplet and divide molecules in the two chips. As an initial demonstration of the technology, we co-measured mRNA transcript and proteins using RNA sequencing and mass spectrometry methods, respectively. 3. The surface chemistry of two droplet array chips are adjusted to specifically enriching different types of molecules. The surface can be modified to be hydrophobic to enrich proteins from cell lysates; alternatively, the surface can be modified with poly-T oligos to enrich mRNA molecules. 4. The merge-and-split workflow can be performed for many cycles to enhance mixing and allow efficient enrichment on nanowell surfaces. 5. We demonstrated the method with integrated transcriptomics and proteomics of single cells. It can be applied to other omics analysis, such as mRNAs/metabolites; proteins/metabolites; intact proteins/digested proteins, etc.
