Abstract

Disclosed herein are methods for synthesis of ultra-high molecular weight polyethylene (UHMWPE), with improved disentanglement, for solid-state processing into a product, such as tapes, films, and ropes, etc., with superior mechanical properties. The method includes using a catalyst support which includes MgCl2 pre-reacted with different alcohols. The MgCl2/alcohol adducts are reacted with different aluminum alkyls to form nanoparticles support, preferably in-situ, under inert environment in the presence of the monomer used to synthesize the UHMWPE. The resulting heterogeneous catalytic system and polymer synthesis method results in improved UHMWPE with high average molecular weight (Mw)>1 million g/mol, with lower levels of entanglement (while avoiding fouling seen with homogenous catalytic systems), allowing for processing into products such as tapes with superior mechanical properties.

Abstract

A method for diagnosing a disease, such as breast cancer, in a biological sample using spectroscopic data is described. The method involves a computer-implemented method that converts spectroscopic vibrational from the sample into a profile and scores the profile using a pair of reference profiles. Based on the score and a threshold, it can be determined whether the subject from which the sample was obtained has a disease, and, if so, to what extent. The method also allows detection of early and pre-disease states in subjects based on the detection of the signal of low concentration analytes that are indicative of early or incipient disease states. The method is non-invasive, non-subjective, highly specific, and sensitive. The method affords the application of a single standard of diagnostic accuracy, independent of the availability of expert pathologists.

The reactor may include an upper reactor portion defining an upper reaction zone and a lower reactor portion defining a lower reaction zone. The catalyst may move in a generally downward direction through the upper reactor portion and the lower reactor portion, and the hydrocarbon feed stream may move in a generally upward direction through the lower reactor portion and upper reactor portion such that the hydrocarbon feed stream and the catalyst move with a counter-current orientation. Contacting the catalyst with the hydrocarbon feed stream may crack one or more components of the hydrocarbon feed stream and form a hydrocarbon product stream.

Abstract

A method for capturing carbon dioxide (CO2) from a humid gas stream is provided. In certain embodiments, the gas stream is a humid natural gas combine cycle (NGCC) exhaust stream. In certain embodiments, the gas stream is a humid air stream. The humid gas stream comprises CO2 and oxygen (O2). In the method, the humid gas stream is contacted with a metal organic framework (MOF) material KAUST-7. The CO2 from the humid gas stream is captured with the KAUST-7 MOF material to generate a CO2-concentrated gas stream comprising approximately 1-30% of CO2.

Abstract

Rapid, sensitive, and specific point-of-care testing for pathogens is crucial for disease control. Lateral flow assays (LFAs) have been employed for nucleic acid detection, but they have limited sensitivity and specificity. A fusion of catalytically inactive Cas9 endonuclease and a relaxase for example, VirD2 are used for sensitive, specific nucleic acid detection by LFA. VirD2-dCas9 specifically binds the target nucleic acid sequence via dCas9 and covalently binds to a FAM-tagged oligonucleotide via VirD2. The biotin label and FAM tag are detected using a LFA. This system, termed Vigilant (VirD2-dCas9 guided and LFA-coupled nucleic acid test) is coupled to reverse transcription-recombinase polymerase amplification to detect pathogenic nucleic acid of interest in a sample, it exhibits an impressive limit of detection and shows no cross-reactivity, thus reducing incidents of false positives. Vigilant offers an easy-to-use, rapid, cost-effective, and robust detection platform for SARS-CoV2.

Abstract

An active flash-light treatment system is configured to degrade organic pollutants in a liquid stream. The system includes a reactor configured to receive the liquid stream, a light source configured to generate an emitted light having a first wavelength range, an upstream sensor configured to measure a characteristic of the liquid stream before entering the reactor, and a controller configured to analyze the characteristic of the liquid stream and to select a wavelength-conversion material for the reactor, based on the characteristic of the liquid stream. The wavelength-conversion material is configured to absorb the emitted light and generate a converted light having a second wavelength range, different from the first wavelength range, and the converted light irradiates the liquid stream to degrade the organic pollutants.
