First, CdS nanoparticles were synthesized in a planetary ball mill through a solid-state ion exchange reaction. In the second step, Cd2+ ions were partially replaced by Zn2+ ions at the surface of the nanoparticles using solvent free long-term activation in a high-energy planetary ball mill. The optimal activation time in a ball mill was determined to be 45 min. Spherical CdS nanoparticles with a diameter of 10 nm and modified CdS@ZnS (45 min) nanocomposites  were characterized by X-ray diffraction analysis, Raman and UV-vis spectroscopy, and scanning electron microscopy. The ability of nanocomposites for photocatalytic water purification was tested on the degradation of the model organic dye Orange II in an aqueous solution under the visible light irradation. The modified CdS@ZnS nanocomposites showed higher photocatalytic activity compared to the original CdS nanoparticles.","PeriodicalId":41021,"journal":{"name":"International Journal of Biology and Chemistry","volume":"20 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139157611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alkali-silicate raw mixtures in combination with high-performance fillers currently make it possible to create porous heat-insulating materials with unique properties: rigid cellular structure, specified geometric dimensions and shape, low thermal conductivity, incombustibility, high processability, environmental friendliness, etc. at a relatively low cost. The use of such heat-insulating materials in construction allows solving the problems of energy saving, accessibility and cost-effectiveness. The article considers possibility of obtaining heat-insulating material based on sodium silicate (silicate glue \"Polipax\") and natural material - flasks from Taskalinsky deposit of West Kazakhstan region. Technical characteristics of Polypax glue are given. Using a scanning electron microscope, elemental, chemical, and oxide compositions of the flask were studied. A recipe for a heat-insulating composite material (HCM) has been compiled.To assess the quality of the obtained HCM, its physical and mechanical characteristics were determined: density, water resistance, thermal conductivity, strength. Samples I-II in terms of density and strength showed the best results, and samples III-IV differ slightly from the technical conditions in terms of the studied indicators. It has been determined that the obtained HCM using flask as filler has a positive effect on the performance properties of the heat-insulating material, and is also economically viable, because local raw materials are used. Thus, it is possible to use flask from Taskalinsky deposit of West Kazakhstan region as filler for heat-insulating material.","PeriodicalId":41021,"journal":{"name":"International Journal of Biology and Chemistry","volume":"18 6","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139157638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changes in physiological indicators such as weight, height, vital capacity, glossopharyngeal inhalation (GI), blood pressure, heart rate, physical performance, endurance according to the physical work capacity test at a heart rate of 170 beats per minute (PWC 170) and membrane patch colorimetry (MPC) tests, and heart rate variability are shown, with the calculation of the main indices of the humoral-vegetative balance. The results showed that the vital capacity of the lungs and tidal volume in athletes were 6-8% lower than the required values and corresponded to the “average level” of the functional capabilities of the respiratory system. Calculations of the Skibinsky, Robinson, and Shapovalova indices showed a functional insufficiency in the adaptation of the cardiorespiratory system to physical activity. Against the background of the development of muscle strength functions, indicators of physical performance and endurance of athletes (PWC 170 and maximum oxygen consumption (MOC) tests) turned out to be “below average” levels in absolute and relative values. To identify hidden functional disorders of the cardiovascular system, variability studies were conducted on heart rate (HRV), the results of which showed that 60% of athletes (in all groups), regardless of the type of sport, had a good level of functional capability of the cardiovascular system. The remaining athletes revealed a low level of adaptation mechanisms and functional state of the cardiorespiratory systems, the reason for which was insufficient training of the body of endurance athletes. Research has shown that athletes who have not previously engaged in special training for endurance and increased performance need to develop cardiorespiratory capabilities that ensure the activity of metabolic processes and replenish energy reserves for successful sports activities.","PeriodicalId":41021,"journal":{"name":"International Journal of Biology and Chemistry","volume":"8 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139157740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been used ornamental shrubs. The study was made about the pyrimidinecarboxylic acids effect on the seed germination and the seedling height of Rhododendron species. The diversity of seeds is manifested in their heterogeneity according to morphological characteristics (the seedling height) and sowing qualities (seed germination) of Rhododendron species. The sowing properties (germinating capacity, seedling growth) were improved after treating the seeds with the organic compounds. There is the trend of increasing the seed germination and the seedling height of Rhododendron depended on the concentration of applied compounds. The seed germination for Rh. ledebourii, Rh. luteum, Rh. molle was increased from 5 to 7%, for Rh. schlippenbachii – from 5 to 10%. The seed treatment with pyrimidinecarboxylic acids at concentrations 0.01%, 0.05% and 0.1% allows to increase the seedling height for Rh. ledebourii from 37.5 to 75%, for Rh. luteum, Rh. molle - from 18.2 to 45.5%, for Rh. schlippenbachii from 20 to 40% concerning the control. To increase the seedling height, 2-benzylamino-4-methylpyrimidine-5-carboxylic acid at concentrations 0.05% and 0.1% is most effective.
