FTIR and FT-Raman Spectroscopic Study on Polymer Based High Pressure Digestion Vessels

, 2006
Surface corrosion of polytetrafluoroethylene (PTFE) based microwave digestion vessels was monitored by reflection FTIR and FT-Raman techniques. Samples were taken from digestion vessels after 0 (new), 50, 100, and 200 digestion cycles of milk powder. The

Monitoring cell cycle distributions in MCF-7 cells using near-field photothermal microspectroscopy. [PDF]

, 2005
Microspectroscopic techniques such as Fourier transform infrared (FTIR) have played an important role in "fingerprinting" the biochemical composition of cellular components.

A multivariate data approach for FTIR-ATR monitoring of virgin olive oils: Lipid structure during autoxidation

Oilseeds and fats, crops and lipids, 2019
In this study, fresh and 12 month stored virgin olive oils (VOOs) were monitored with Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) as a quick, non-destructive and no chemical used method.

Facile Preparation of Carbon Membranes Derived from a Fluorenyl‐Containing Polyimine for Selective Hydrogen Separation

Advanced Functional Materials, EarlyView.
A fluorenyl‐containing polyimine is introduced as a simple, scalable precursor for high‐performance carbon membranes. The precursor's intrinsic kinked structure enables defect‐free membrane formation with enhanced hydrogen permeance and excellent ideal selectivities for key industrial gas pairs (H2/N2, H2/CH4, and H2/CO2), offering a practical route ...

Polarised ATR-FTIR characterisation of cellulosic fibres in relation to historic artefacts

, 2004
The utility of polarised attenuated-total-reflectance (ATR) FTIR spectroscopy was investigated for the identification of cellulosic fibres and characterisation of their state of degradation.Turning the polariser so that the electric vector is parallel ...

FTIR Study of Glyphosate−Copper Complexes

Journal of Agricultural and Food Chemistry, 2002
Complexes of the herbicide glyphosate (GPS) and the heavy metal Cu were studied by infrared spectroscopy under controlled pH, in order to know the mechanisms involved in the formation of these complexes. In CuGPS(-), the IR spectrum shows participation of the carboxylate and phosphonic moieties of the GPS molecule. The formation of the complex produces

Self‐Adaptive Anhydrous Passivation Mitigates Open‐Circuit Voltage Loss in Pb‐Sn Mixed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
In this report, a self‐adaptive anhydrous passivation strategy is introduced by incorporating trimellitic anhydride (TMAH) into the perovskite precursor. In situ hydrolysis of TMAH yields trimellitic acid (TMA); ‐C═O/‐COO− groups of TMAH/TMA form a chelate with undercoordinated Pb2+/Sn2+, regulate nucleation, promote (100) orientation, passivate ...

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

Advanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.
