1990年8月1日 · In the present work we show that proton NMR spectra of PEGs dissolved in deuterated dimethyl sulfoxide (but not other solvents) reveal a hydroxyl peak at 4.56 (±0.02) …

pH-responsive docetaxel-conjugated poly (lactic acid) (PLA)-polyethyleneglycol (PEG) micellar formulation was synthesized via acid labile hydrazone linkage. Levulinic acid (LEV) was used …

2020年10月5日 · Raman peak at 1100 cm −1 is a measure of the molecular weight for short PEG molecules. Experimental Raman spectra of liquid and solid polyethylene glycols (PEGs) with …

2023年1月18日 · Polyethylene glycols (PEG) are commonly used for the functionalization of biomacromolecules and nanoparticles because their high hydrophilicity increases the …

Fourier‐Transform Infrared (FTIR), Raman, and Nuclear Magnetic Resonance (NMR) analysis showed successful synthesis of PEG‐PUSe‐PEG block copolymer. A long‐term zero order …

1998年4月30日 · Polymer electrolytes prepared with lithium perchlorate and low molecular weight poly(tetramethylene glycol) (PTMG) homopolymer and PTMG/poly(ethylene glycol) (PEG) …

In the example of poly(ethylene glycol) (PEG) acetyl triarm, the number average molecular weight was determined with great ease. In the case of the compositional analysis of a commercial …

To investigate the behaviours of polyethylene glycol (PEG) and its interaction with biomass constituents in coniferous wood (Japanese cypress), variable temperature solid-state NMR …
