Abstract: Wet impregnation of active metal precursors into porous substrates, together with selective adsorption of the precursors on the pore surfaces, enables transition metal oxides derived from the precursors to disperse throughout the substrate, even at the nanoscale, without increased sintering or agglomeration, thereby forming oxygen carriers suitable for chemical looping. The porous substrate can be an oxide, for example SiO2. The oxygen carriers can comprise relatively large oxide loadings of over about 20 wt % and exhibit high reactivity over many regeneration cycles with substantially no loss in oxygen transport capacity or decrease in kinetics. The use of multiple transition metal oxides, for example NiO in addition to CuO, can greatly enhance chemical looping performance.

Abstract: A method of detecting and diagnosing cancers characterized by the presence of at least one nodule/neoplasm from an imaging scan is presented. To detect nodules in an imaging scan, a 3D CNN using a single feed forward pass of a single network is used. After detection, risk stratification is performed using a supervised or an unsupervised deep learning method to assist in characterizing the detected nodule/neoplasm as benign or malignant. The supervised learning method relies on a 3D CNN used with transfer learning and a graph regularized sparse MTL to determine malignancy. The unsupervised learning method uses clustering to generate labels after which label proportions are used with a novel algorithm to classify malignancy. The method assists radiologists in improving detection rates of lung nodules to facilitate early detection and minimizing errors in diagnosis.

Abstract: A process to prepare a carbon molecular sieve adsorbent composition comprises steps beginning with an activated carbon having specific effective micropore size. The activated carbon is impregnated with monomers or partially polymerized polymer, allowed to complete polymerization, and then carbonized such that the impregnant shrinks the micropores to another specific effective micropore size. Finally, the impregnated/polymerized/carbonized product is annealed at a temperature ranging from 1000° C. to 1500° C., which ultimately and predictably shrinks the micropores to a size ranging from 4.0 Angstroms to 4.3 Angstroms. The invention surprisingly enables fine tuning of the effective micropore size, as well as desirable selectivity, capacity and adsorption rates, to obtain highly desirable carbon molecular sieving capability particularly suited for use in, for example, fixed beds in pressure swing or temperature swing processes to enable propylene/propane separations.

Abstract: In oil spill clean-up, a sorbent is material that is used to absorb oil and repel water. Sorbents are used very frequently, but many of them tend to be expensive or inefficient. Based on extensive research, it is found that a combination of polypropylene, polyester, reclaimed newspaper print, and vermiculite makes a very effective filler for a sorbent.

A non-provisional utility patent will protect this ratio and introduce a competitive, cost-effective, and eco-friendly sorbent into the market.
