Among the currently used methods of monitoring human tissues and their components many types of research are distinguished. These include spectroscopic techniques. The advantage of these techniques is the small amount of sample required the rapid process of recording the spectra, and most importantly in the case of biological samples - preparation of tissues is not required. In this work vibrat...

Interfacial oxidation and reduction of Prussian Blue (PB), KFe[Fe(CN)6]‚nH2O (n ≈ 10), powder were probed in situ with Fourier transform infrared attenuated total reflection (FT-IR/ATR) spectroscopy. The combination of electrochemistry in the absence of liquid electrolyte with internal reflectance FT-IR spectroscopy was accomplished using a simple two-electrode sandwich-type cell in which a cry...

Thermodynamic parameters for the complex formation of Am(iii) and Eu(iii) with lactate were determined with UV-vis and time-resolved laser-induced fluorescence spectroscopy (TRLFS) in a temperature range between 25 and 70 °C. The reaction enthalpy decreased with increasing ionic strength. ATR FT-IR and NMR spectroscopy in combination with density functional theory (DFT) calculations revealed st...

Cystinuria is the commonest inherited cause of nephrolithiasis (~1% in adults; ~6% in children) and is the result of impaired cystine reabsorption in the renal proximal tubule. Cystine is poorly soluble in urine with a solubility of ~1 mM and can readily form microcrystals that lead to cystine stone formation, especially at low urine pH. Diagnosis of cystinuria is made typically by ion-exchange...

Abstract Operando attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy is discussed in this paper for water splitting application. The first part of the focuses on discussion opportunities and challenges method characterization solid-liquid interface splitting. second recent results future perspectives. We present stable robust operando ATR-FTIR measurements using low ...

objective(s): to improve water stability of electrospun chitosan/ polyethylene oxide (peo) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.  materials and methods: different amounts of genipin were added to the chitosan/peo solutions, chitosan/peo weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

L-cysteine is a food additive that used in bakery ingredient. It as stabilizer to soften the texture of dough. However, primary sources could be controversial it might derive from animal and human parts. This study aimed differentiate by using Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) Raman spectroscopy. Raw materials pig bristles, hair, cow horn, duck feather chicken we...

background and objectives: attenuated total reflectance-inferared (atr-ir) spectra can be used as a non-invasive fingerprinting approach in quality control of herbal samples. methods: twenty versatile herbal samples were subjected to attenuated total reflectance-inferared (atr-ir) spectroscopy followed by different clustering methods in order to determine by which method more reasonable classif...

Chitosan and poly(methyl methacrylate) (PMMA) composites were synthesized by polymerization with heating mechanochemical method. The obtained polymer analyzed the ATR FT-IR spectroscopy presence of intermolecular hydrogen bonds hydrophobic interactions in formation PMMA chitosan was shown.
