Hydration in thermo-responsive oligoether methacrylate hydrogels studied by FT-IR spectroscopy

Influence of Ethylene Glycol Methacrylate to the Hydration and Transition Behaviors of Thermo-Responsive Interpenetrating Polymeric Network Hydrogels

The influence of ethylene glycol methacrylate (EGMA) to the hydration and transition behaviors of thermo-responsive interpenetrating polymeric network (IPN) hydrogels containing sodium alginate, N-isopropylacrylamide (NIPAAm), and EGMA were investigated. The molar ratios of NIPAAm and EGMA were varied from 20:0 to 19.5:0.5 and 18.5:1.5 in the thermo-responsive alginate-Ca2+/P(NIPAAm-co-EGMA) IP...

FT-IR Photoacoustic Spectroscopy

FT-IR Spectroscopy in Medicine

Infrared spectroscopy has been widely applied for the characterisation of various substances. Due to its sensitivity to the chemical information and architecture of the molecule, infrared spectroscopy can play an important role in new applications such as in the life-science field and not only in the traditional fields of physics and chemistry. Spectroscopic techniques are simple, reproducible,...

Ultrastructural Aspects of Pulp Fibers as Studied by Dynamic FT-IR Spectroscopy

Dynamic (or 2D) FT-IR spectroscopy in combination with polarized IR irradiation has been used in this work to study wood polymer orientation and interactions on the ultrastructural level in wood fibers in the native state as well as the effects of different pulping processes. The wood polymer interactions were studied under both dry and humid conditions. The matrix of lignin and hemicelluloses ...

Molecular Structural Analysis of Spider's Capture Thread and Viscid Droplets Studied by Microscopic FT-IR Spectroscopy.

The molecular structural analysis of capture thread, including its viscid droplets of oriental golden orb-web spider Nephila clavata, has been performed by microscopic FT-IR spectroscopy. The obtained spectra of capture threads with and without viscid droplets indicate that the features in the region of 1400 - 1000 cm-1 will be useful as marker bands for the degree of the dissolving of viscid d...
