Furthermore, FESEM and EDS were employed for microstructural analysis to clarify the corresponding changes in the concrete matrix. The experimental results indicate that the incorporation of CQDs significantly enhances the overall performance of concrete.

The synthesis of these ionic compounds consists mainly in heterocyclization reactions under the action of halogens on various 3-alkene(alkyne)ylsulfanyl-5H-[1,2,4]triazino[5,6-b]indoles. In this work, we first described the heterocyclization of 3-allylsulfanyl-5-benzyl-[1,2,4]triazino[5,6-b] indole, which proceeds similarly to the heterocyclization of its 5-unsubstituted derivative with the formation of 3-bromomethyl-10-benzyl[1,3]thiazolo[3',2':2,3][1,2,4]triazino[5,6-b]indolium halides. In the series of [1,3]thiazino[1,2,4]triazinoindoles, by the reaction of 8-bromo-3-butenylsulfanyl-5H-[1,2,4]triazino[5,6-b]indole with iodine (bromine), we obtained previously unknown 8-bromo-4-halomethyl[1,3]thiazino[3',2':2,3][1,2,4]triazino[5,6-b]indolium halides. In addition, the supramolecular structure of the known 4-iodomethyl[1,3]thiazino[3',2':2,3][1,2,4]triazino[5,6-b]indolium triiodide was studied for the first time by X-ray diffraction. 3‑Methyl[1,3]thiazolo[3',2':2,3][1,2,4]triazino[5,6-b]indole was selected as a non-ionic compound for studying activity against both anthropophilic and phytopathogenic microscopic fungi, for which we also proposed another fairly simple synthesis method that enables a maximum yield of 75%. Studying antifungal activity has demonstrated that the greatest activity against almost all types of phytopathogenic fungi and high antimycotic activity (BMD = 3.12 μg/mL) against the culture of the fungus T. rubrum is exhibited by the previously described 3-(iodomethylene)-2,3-dihydro-10H[1,3]thiazolo[3',2':2,3][1,2,4]triazino[5,6-b]indolium triodide.","PeriodicalId":530,"journal":{"name":"Doklady Chemistry","volume":"521 4","pages":"201 - 210"},"PeriodicalIF":0.6,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key challenge in this field is that GNPs are effective fluorescence quenchers, which dramatically reduces the detection sensitivity of flow cytometry and fluorescence bioimaging. This is particularly relevant for fluorescein, whose emission wavelength is lower than the plasmon resonance wavelength of GNPs. However, no studies are available addressing methods for overcoming its quenching upon adsorption onto GNPs. We propose an approach for covalently attaching fluorescein to GNPs via an optimized linker –PEG71–NH–(CH2)6–NH–, which allows the GNPs and fluorophore to be separated by the distance necessary to overcome the quenching effect. The method involves modifying GNP-S-PEG-COOH with hexamethylenediamine, followed by the addition of a fluorophore in the form of a succinimide ester. Fluorescent GNP-based conjugates with diameters of 12.7 and 6.1 nm (GNP-Flu-13 and GNP-Flu-6, respectively) capable of efficient cell penetration, were synthesized. All intermediate products and the target GNPs, Flu-13 and Flu-6, were characterized using dynamic light scattering, optical spectroscopy, transmission electron microscopy, and gel electrophoresis. The developed fluorescent GNP conjugates can be effectively used for in vivo tumor tissue bioimaging.","PeriodicalId":530,"journal":{"name":"Doklady Chemistry","volume":"521 3","pages":"117 - 125"},"PeriodicalIF":0.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148871612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been shown that the introduction of citric acid accelerates self-organization and leads to the formation of nanoparticles and supramolecular complexes of the Ag0/Ag+/Cys type. It has been found that these systems form a silver nanoparticle sol with particle sizes ranging from 15 to 50 nm and a zeta potential of approximately 75 mV. The degree of dissociation of silver citrate and the concentration of citrate anions play a key role in the self-organization mechanism. An increase in the content of citrate anions promotes the growth of the hydrodynamic diameter of particles (up to 80–170 nm) and the formation of micron-sized aggregates, which is confirmed by zeta potential data (5–35 mV). These results are important for understanding the mechanisms of nanostructure formation based on biomolecules and metal ions and can be used in the development of new functional materials.","PeriodicalId":530,"journal":{"name":"Doklady Chemistry","volume":"521 3","pages":"126 - 133"},"PeriodicalIF":0.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148871613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper discusses the application of nanorods in enhancing solar cells, LCDs, photodetectors, and displays. This shows that the ways to alter optical and electrical properties for various applications are possible. The review highlights advances that have taken place with these nanostructures in luminescent optoelectronics, such as enhancement in photoluminescence, improvement in charge carrier mobility, and localized surface plasmon resonance. The demonstration of their extensive use in energy harvesting, sensing, and high-resolution displays is mentioned as a major finding. Nevertheless, such obstacles as scalability, stability, and environmental impact still exist, and large-scale implementation is a challenge. To address these challenges, new strategies in the field of surface modification and integration of materials have been reported. Based on a comprehensive literature review, several experimental studies, synthesis innovations, and device integrations were reported. The review, by using correlation between nanorod structural and functional characteristics and device performances, presents paths to the optimization of optoelectronic efficiencies and durabilities. The findings underscore the possible game-changing potential of nanorods in optoelectronics, culminating in a new breed of energy-threatening, miniaturized, and flexible devices. Accordingly, the review provides the framework for future studies, where interdisciplinary studies are necessary to harness the potential of nanorods as next-generation optoelectronics.","PeriodicalId":530,"journal":{"name":"Doklady Chemistry","volume":"521 3","pages":"134 - 172"},"PeriodicalIF":0.6,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148871576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spent perlite, comprising nearly 70–76% organic residues such as oils and waxes, was regenerated through controlled calcination at 550°C for 120 min, achieving complete removal of the organic fraction. The regenerated material was subjected to alkaline extraction and acid precipitation, enabling the recovery of amorphous SiO2. Increasing the alkali treatment duration from 8 to 24 h enhanced the yield of SiO2 from 39.04 to 54.3%, while the accompanying zeolite by-product decreased from 60.96 to 45.3%. Structural characterization confirmed the transformation into a micro–mesoporous silica network with a high specific surface area, up to 383 m2/g. Comparative analyses with commercial silica demonstrated that regenerated SiO2 exhibits superior sorption properties, underlining its potential for adsorption and catalytic applications. The novelty of this work lies in demonstrating, for the first time, that industrially discarded perlite used in oil purification can be regenerated and converted into high-performance silica-based adsorbents. This approach not only reduces dependence on virgin raw materials but also contributes to waste valorization, resource efficiency, and the development of sustainable silica production routes.","PeriodicalId":530,"journal":{"name":"Doklady Chemistry","volume":"521 2","pages":"86 - 101"},"PeriodicalIF":0.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148357920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
