The development of aqueous absorbents for CO capture is significantly important to reduce global industrial gas emissions through high regeneration efficiency and low energy consumption. Herein, we newly designed and prepared a dihydroxylated ionic liquid (IL) bis(2-hydroxyethyl)dimethylammonium 1,2,4-triazole ([N][T]) for highly efficient CO absorption through anion-cation cooperative interactions. A superior capacity of 1.

The properties of MACF were characterized using Fourier-transform infrared spectroscopy, elemental analysis, and high-resolution F NMR. MACF, chitosan, primary and secondary amine, octadecylsilane, graphitized carbon black, Z-Sep, Z-Sep , and EMR-Lipid were compared in terms of extraction efficiency.

Large amounts of medical data are collected electronically during the course of caring for patients using modern medical information systems. This data presents an opportunity to develop clinically useful tools through data mining and observational research studies. However, the work necessary to make sense of this data and to integrate it into a research initiative can require substantial effort from medical experts as well as from experts in medical terminology, data extraction, and data analysis.

We are developing a series of components from which to construct NLP pipelines. These pipelines typically begin with a component whose goal is to label sections within medical documents with codes indicating the anticipated semantics of their content.

Mono-2-ethylhexyl phthalate (MEHP) is one of the most complicate metabolites from DEHP in vivo and responsible for many toxic effects of DEHP. In order to evaluate human exposure to DEHP, a direct competitive enzyme-linked immunosorbent (dcELISA) based on monoclonal antibody (mAb) was developed to detect MEHP.

Materials And Methods: We developed a system that automates the creation of diagnostic decision-support applications.
A compound is identified by matching its proton and/or carbon NMR spectra to NIH PubChem molecular structures. The matching process involves analyzing 1D proton, 1D carbon, DEPT, and/or HSQC spectra, and comparing the number of NMR resonances, detected proton and carbon shifts, likely number of methyl- and methoxy-groups, and an optionally specified molecular formula to predicted proton and carbon shifts of PubChem structures. A structure verification module rates the consistency between experimental spectral analysis results and a proposed structure (not limited to PubChem structures) and assigns observed shifts to the proposed structure.
