The fruits of anise contain different classes of biologically active compounds, due to which they have antidepressant, antiperoxidant, antidiabetic effect; extracts of this plant have an antibacterial effect. Professional literature lacks information on the chemical composition of anise herbs and prospects for their use in medicine. The aim of the work is to study of the morphological and anatomical structure of the aboveground organs of anise and to establish of macro- and microscopic diagnostic characters necessary for the identification of the plant raw materials. Materials and methods. Anise herbs consisting of stems, leaves flowers, and unripe fruits were used for the study. Fresh and dried raw materials were macroscopically analyzed with the naked eye and using a magnifying glass (×10). Studies of transverse and longitudinal sections, epidermis and surface preparations were performed using conventional techniques: with microscopes MBS 9, MS 10 (glasses ×5, ×10, ×15, lenses ×10, ×40), Micromed XS-4130 (eyepiece WF15X, lenses ×40/0.65, ×10/0.25) with a photomicrographic attachment. The micrographs were taken with Samsung PL50 camera. Results. As a result of the macro- and microscopic analysis, diagnostic properties of anise herbs were established. Conclusions. It is for the first time that macro- and microscopic characteristics of anise herbs were studied, which confirms the identity of raw materials.

For the first time, the morphological and anatomical structures of the leaves of different age individuals of the medicinal and rare species F. tadshikorum were studied in Tashkent Botanical Garden. Currently, natural populations of the species are in decline, and for the preservation and production of medicinal raw materials, research on the ex situ development conditions is needed. According to the results, adaptive responses to new habitat conditions in the anatomical structures of the vegetative organs were found. Plants of juvenile and immature development stages retained the the mesophyll's isolateral-palisade type, but differed in other quantitative and qualitative indicators of leaf tissues. Immature plants of the second year of life with more developed leaves showed modifications in the anatomical structure of the leaves, with powerfully developed vascular bundles, mechanical tissue, secretory ducts, as well as the presence of deep fibers both above the phloem of peripheral bundles, and also above the phloem of the central bundles of the petiole.

The article presents the results of microscopic analysis of the leaves of L. officinalis. The main anatomical and diagnostic features that can be used in identifying and evaluating the authenticity of medicinal plant raw materials are established. Analysis of the anatomical structure showed that the leaves of L. officinalis are dorsoventral; the leaf plastic is hypostomatic, and the stomatal apparatus is anomocytic. The main vein of the leaf blade and petiole is represented by a bicollateral conducting bundle. Idioblasts represented by round- shaped essential oil cells were first identified in the columnar and spongy mesophyll of the leaf and petiole. Single diamond-shaped crystals and calcium oxalate druses were also found in the leaves. The information obtained can serve as a basis for the development of the section "Microscopy" in the draft regulatory documentation.

Dicalcium silicate (Ca2SiO4) is a major component of Portland cement. It has also been investigated as a potential transformation toughener alternative to zirconia. It has five polymorphs: α, α'H, α'L, β and γ. Of interest is the β-to-γ transformation on cooling at about 490°C. This transformation, accompanied by a 12% volume increase and a 4.6° unit cell shape change, is analogous to the tetragonal-to-monoclinic transformation in zirconia. Due to the processing methods used, previous studies into the particle size effect were limited by a wide range of particle size distribution. In an attempt to obtain a more uniform size, a fast quench rate involving a laser-melting/roller-quenching technique was investigated.The laser-melting/roller-quenching experiment used precompacted bars of stoichiometric γ-Ca2SiO4 powder, which were synthesized from AR grade CaCO3 and SiO2xH2O. The raw materials were mixed by conventional ceramic processing techniques, and sintered at 1450°C. The dusted γ-Ca2SiO4 powder was uniaxially pressed into 0.4 cm x 0.4 cm x 4 cm bars under 34 MPa and cold isostatically pressed under 172 MPa. The γ-Ca2SiO4 bars were melted by a 10 KW-CO2 laser.

Barium hexaferrite (BaFe12O19) is a promising candidate for high density magnetic recording media due to its superior magnetic properties. For particulate recording media, nano-sized single crystalline powders with a narrow size distribution are a primary application requirement. The glass-crystallization method is preferred because of the controllability of crystallization kinetics, hence, particle size and size distribution. A disadvantage of this method is the need to melt raw materials at high temperatures with non-reactive crucibles, e.g. platinum. However, in this work, we have shown that crystal growth of barium hexaferrite occurred during low temperature heat treatment of raw batches.
