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.

Article Synopsis
- * Raman spectroscopy is highlighted as an effective method for monitoring changes in the structure of these glycol solutions over time, especially how water content decreases on substrates.
- * The study also reveals that the water content reduction affects the presence of certain molecular conformations in the glycols and demonstrates that a specific laser wavelength (1064 nm) is effective for analyzing antifreeze products containing dyes.
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.

In this work, we study two series of the copolymers of L-lactide (LLA) and ε-caprolactone (CL) with the CL molar content of 5, 15, and 30 %. The first series was the commercial semicrystalline granules (Corbion, Netherlands), which we analyzed without any additional modification. The second series was amorphous films, prepared from the granules by hot pressing with the subsequent fast quenching in order to avoid the crystallization.

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.
