Diagnostics of Aging of Transformer Oils Based on Their Transmission Spectra in the Visible Range This article examines the visible transmission spectra of transformer oils (TOs) as indicators of their aging. While aging is traditionally associated with oxidation, the authors identify an alternative mechanism – the accumulation of aromatic compounds that degrade the oils“ performance. Using spectroscopy, the authors established a relationship between transmission spectra, molecular absorption, and Rayleigh scattering by dispersed particles formed during aging. A direct correlation was found between aging and changes in transparency caused by increasing concentrations of dispersed particles and aromatic compounds. These data are important for operational quality control of oils and predicting their replacement intervals.

Low Detection Limits in Chemical Analysis. A Review of Current Advances 10.22184/2227-572X.2026.16.2.124.132
A targeted search of scientific publications was conducted to establish the lowest limits of detection (LODs) achieved in modern chemical analysis. The lowest LODs were identified and classified into four groups of analytes of different nature. Each group is characterized by the 10 lowest limit values and their average values expressed in units of molar concentration of the solution (metals – 1.2 · 10−19 М, low organic molecules – 1.7 · 10−20 M, biopolymers – 1.3 · 10−22 M) or volume fraction in a gas mixture (7.2 · 10–16). The distribution of LODs for different analytes within these groups is considered, and the groups are compared. The data presented reflect the capabilities of modern analytical instruments, primarily new chemical sensors. These sensors have emerged due to the rapid development of nanotechnology and biotechnology (biosensors) and are driven by the need to detect very low concentrations for environmental protection, healthcare support, including early disease detection, food quality control, and various types of safety.

Patenting in Scientific Research This article examines the specifics of patenting in scientific research. Key concepts in patent law ‒ such as results of intellectual activity, intellectual property, invention, utility model, and patentability conditions ‒ are discussed, including in the context of the chemical industry. Fundamental approaches to filing a patent application are described. The process of preparing for patenting in biomedical research is examined in detail, using the example of developing treatments for nocturnal enuresis in children and adolescents at the Children“s City Clinical Hospital No. 9 named after G. N. Speransky. Particular attention is paid to the statistical processing of the results of a scientific experiment conducted for patenting purposes with a small sample size.
