The need to limit antibiotic therapy due to the spreading resistance of pathogenic microorganisms to these medicinal substances stimulates research on new therapeutic agents, including the treatment and prevention of animal diseases. This is one of the g
The 405 nm pump beam, having 150 femtoseconds pulse duration at 80 MHZ repetition rate, was generated by frequency doubling the fundamental at 810 nm from the Ti:Sapphire laser (Spectra Physics) using a SHG BBO crystal. The 533 nm probe beam was generated by combining the 810 ...
Melting points were determined on an OptiMelt MPA100 apparatus (SRS, USA) without correction. FT-IR spectra were recorded on a Thermo Scientific Nicolet Summit FT-IR Spectrometer (Thermo Scientific, USA) with KBr methods in the 4000–500 cm−1range. NMR measurements were performed on a Bru...
How to interpret an IR spectrum and an FTIR spectrum FTIR spectra are information rich, but this very fact can make using and interpreting them challenging. A useful primer for interpreting FTIR can be foundhere. Even a simple, pure, single compound sample, like vani...
From the in situ PL and absorbance spectra, we can propose that the spin-coated perovskite thin film suffers morphological evolution from viscoelastic layer to elastic layer-capped viscoelastic bilayer. The formation of the elastic capping layer is due mainly to the antisolvent, which drives solvents...
aPhenyltriethylammonium (PTEA) has 0 hydrogen-bond donor due to its quaternary amine. Powder X-ray diffraction (XRD) spectra of bare (b) and PTEAI-capped MAPbI3(c), when they were degraded for 460 and 640 min The purple shaded area indicates the (110) peak of MAPbI3, and the ...
For example, these manifestations are, say, the observance of fluorescence and phosphorescence, existence of physical fluxes, and ability to register various spectra (microwave, IR, UV-VIS, ESR, NMR, etc.). This exercise results in a framework that resembles with the thermodynamics with internal ...
Recently, MALDI-TOF mass spectrometry (based on the comparison of protein mass spectra with well-characterised reference strains included in reliable databases) is proving to be a commonly used methodology for microbial (mainly bacterial) identification, especially in the clinical fields but also in ...
fungal metabolites; volatile organic compounds; non-volatile compounds; ecological interactions; biotyping; metabolomics1. Introduction Fungi comprise a monophyletic yet unresolved kingdom. At the moment, it is still not possible to diagnose fungi based on specific characters and they should be regarded ...
The comparison of ATR-FTIR spectra before and after ten laundering cycles did not reveal any drastic changes in the chemical composition of the polymer (see Figure S9 in Supporting Information). However, there is a decrease in the intensity of the signal from the polymer coating compared to ...
