Article Synopsis
- Bostrycoidin, a pigment from fungi, has pharmacological significance and indicates Fusarium infections in crops and soils.
- Researchers used density functional theory (DFT) to investigate the molecular structure and properties of bostrycoidin, analyzing its most stable geometry and energy levels of various conformers.
- The study successfully modeled the vibrational and electronic absorption spectra, with the calculated longest-wavelength transition aligning well with experimental results at approximately 498 nm.
The quality of food is one of the emergent points worldwide. Many microorganisms produce toxins that are harmful for human and animal health. In particular, mycotoxins from Fusarium fungi are strictly controlled in cereals.

It may be needed in very different situations: from the nondestructive in situ identification of pigments in paintings to the early detection of fungal infection in major agro-industrial crops and products. So, we propose a prototype method, the key feature of which is a procedure analyzing the lineshape of a spectrum.

- * Optical techniques show promise for identifying these diseases quickly and cost-effectively, but it's essential to find specific spectral markers that indicate contamination.
- * This study utilized various spectroscopy methods and chemometric analysis to differentiate ergot-infected grains using their infrared and reflection spectra, aiming to improve detection in wheat production.
Infection of seeds of cereal plants with fusarium affects their optical luminescent properties. The spectral characteristics of excitation (absorption) in the range of 180-700 nm of healthy and infected seeds of wheat, barley and oats were measured. The greatest difference in the excitation spectra of healthy and infected seeds was observed in the short-wave range of 220-450 nm.

Thermal characteristics of initial samples and after 60 and 220 days of degradation were determined using differential scanning calorimetry. In the process of disintegration, the melting and glass transition temperatures in PLA/NR composites decreased, and in PLA fibers these values increased slightly.

- This paper explores how optical and vibrational spectroscopies can help identify and study the T-2 mycotoxin.
- It uses computer simulations to analyze the structures and properties of T-2 toxin and compares them to a similar compound, 3-deacetylcalonectrin, to find unique spectral features.
- The findings suggest that understanding the structure and spectroscopic characteristics of these molecules can improve detection methods for T-2 toxin and its metabolites.
Non-woven polylactide-natural rubber fiber materials with a rubber content of 5, 10 and 15 wt.% were obtained by electrospinning. The thermal, dynamic, and mechanical properties of the fibers were determined.
View Article and Find Full Text PDFA nonwoven fiber made of polylactide/natural rubber with a rubber content from 0 to 15 wt.% was obtained by electrospinning from a solution. The water sorption test showed that the addition of natural rubber into the polylactide matrix did not significantly affect the degree of water absorption of the fibers, which was in the range of 48.
