Nuclear magnetic resonance (NMR) spectroscopy is a technique that detects the chemical environment of atomic nuclei by the absorption of radio-frequency electromagnetic radiation when in the ...

In this study, the automated fragmentation quantum mechanics/molecular mechanics (AF-QM/MM) method was applied for NMR chemical shift calculations of protein-ligand complexes. In the AF-QM/MM approach ...

After evaporating the solvent with a rotovap, the final product was obtained as colorless liquid (yield 92%). NMR spectrum were measured on a Bruker ultra-shield 400 plus. ATR FT-IR spectra were ...

Howard Energy Partners bought a 120-mile, 12-inch ethylene pipeline from the San Antonio-based EPIC Midstream Holdings. The bidirectional pipeline will provide ethylene transportation through a ...
