The tridentate ligand 2,6-bis(3,5-diphenylpyrazol-1-ylmethyl)pyridine, abbreviated as 2,6-[(3,5-ph₂pz-CH₂)₂-py], a new pyridine-pyrazole derivative, was prepared from 2,6-bis(bromomethyl)pyridine and 3,5-diphenylpyrazole. The ligand was characterized by means of elemental analyses, ATR-IR, ¹H- and ¹³C-NMR spectroscopy and single crystal X-ray crystallography. Using this ligand, a new mononuclea...

The binding of an anionic surfactant onto an anionic surface by addition of divalent ions is reported based on experimental data from specular neutron reflection (NR) and attenuated total internal reflection IR spectroscopy (ATR-IR). Similar measurements using monovalent ions (sodium) do not show any evidence of such adsorption, even though the amount of surfactant can be much higher. This data...

This paper deals with the use of modern Fourier Transform Infrared (FTIR) spectroscopy with quick and easy Diamond Attenuated Total Reflectance (ATR) technique for generating a spectral library of some benzodiazepines of forensic interest. These types of drugs can be seized as bulk street drugs as well as traces found at the scene of crime. There can be legal queries regarding identification of...

In this review, we are reviewing single nucleotide bases using Attenuated Total Reflectance (ATR–FTIR) spectra before moving onto more complex oligionucleotides and ultimately DNA/RNA. This work will lay a foundation to understanding the spectroscopy of DNA/RNA in response to hydration and has important implications for understanding how cells respond to environmental stresses such as dehydrati...

This work describes the characterization of pigments and ground layers in two paintings by renowned Argentinian painter Antonio Berni (1905–1981). The studied are “Toledo” “Figure” from collection Provincial Museum Fine Arts Santa Fe (Argentina). To approach this goal, an integrated investigation comprising situ X-ray fluorescence measurements means a portable system (pXRF), micro-Raman spectro...

The growth mechanism of Atomic Layer Deposition (ALD) on polymeric surfaces differs from inorganic solid substrates, such as silicon wafer or glass. In this paper, we report the experiments Al2O3 and ZnO nonwoven poly-L-lactic acid (PLLA), polyethersulphone (PES) cellulose acetate (CA) fibres. Material in both ALD infiltration mode was studied. structures were examined with a scanning electron ...

In Yemen, most of the medicines are imported. Drugs that enter country by legal means undergo some tests Supreme Board for and Medical Appliances (SBDMA) to evaluate quality product. However, illegally (smuggling) this makes them bypass evaluation their SBDMA. This work was carried out determine physical control parameters authorized smuggled drug products marketed in Aden pharmacies. The brand...

Attenuated total reflection Fourier transform infrared (ATR-FT-IR) spectroscopy of hair fibres shows a discrete transition zone (DTZ) between the hard protective cuticle layer and the softer elongated cortical cells of the cortex. The DTZ is composed of flattened orthocortical cells located on the outer perimeter of the cortex and appears to range in thickness between 2 and 3.6 μm. The inner su...

The Meloidogyne enterolobii Yang and Eisenback nematode represents one of the most devastating pests in guava cultivation Venezuela world. diagnosis this parasite requires specialized knowledge very laborious procedures. objective research was to identify infrared spectra plants, nursery phase, infested with M. using Fourier-transform spectroscopy coupled attenuated total reflectance (FTIR-ATR)...
