Dissolved Organic Matter is a mysterious and still largely unidentified combination of substances that is thought to be ...

Nuclear Magnetic Resonance (NMR) was first experimentally observed in late 1945, nearly simultaneously by the research groups of Felix Bloch, at Stanford University and Edward Purcell at Harvard ...

The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the following table. The multiplicity is shown in parentheses as 1 for singlet, 2 for doublet, 3 for ...

While the temperatures of liquid helium is 4 K (-269 °C), the quench gas temperatures are around 70 - 90 K (600 MHz NMR). Helium gas spreads quickly over the whole room area under the ceiling, and ...

Principle component analysis (PCA) was used to extract components from the solid-state nuclear magnetic resonance (NMR) spectra of bacterial cellulose (BC). Polymers such as cellulose have several ...

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 ...

Equipped with 600 MHz and 700MHz spectrometers equipped with a salt-tolerant 13C-enhanced triple resonance cryo-probe, a 1H,13C capillary flow probe and liquid handling robot and a 1.7mm ...

I currently study intrinsically disordered proteins using solution NMR. Proteins containing disordered domains perform many important cellular functions. My lab currently has two main projects, one to ...
