Synergistic effect and the mechanism of co-roasting spent lithium-ion batteries and nickel matte for metal recovery
No full textRecovering valuable metals from spent LIBs is crucial for sustainable resource utilization and environmental protection. This study proposes an innovative co-roasting process using high-grade nickel matte as a reducing and sulfating agent to achieve efficient selective lithium extraction and simultaneous metal recovery. Through co-roasting at 843 °C, lithium converts to water-soluble Li2SO4, while transition metals (Ni, Co, Mn) form insoluble oxides. Thermodynamic analysis and in situ characterization revealed that SO2 generated from the oxidative decomposition of Ni3S2 drives the selective sulfation of lithium, followed by thermal decomposition of transition metal sulfates at elevated temperatures. Water leaching experiments demonstrated exceptional lithium recovery (99.98 %) with minimal co-dissolution of other metals (<0.1 %), enabling subsequent acid leaching for residual metal recovery. This approach not only simplifies lithium extraction but also integrates the refining of high-grade nickel matte, offering a sustainable pathway for urban resource recycling and primary mineral utilization, with significant industrial potential.This is the peer reviewed version of the paper: Yang, Qian, Huan, Hongxian, Yu, Dawei, Guo, Xueyi, Mitrašinović, Aleksandar, Tian, Qinghua, "Synergistic effect and the mechanism of co-roasting spent lithium-ion batteries and nickel matte for metal recovery" in Journal of Environmental Chemical Engineering, 13, no. 5 (2025):117648, [https://doi.org/10.1016/j.jece.2025.117648

Role of Atomic Oxygen in High Quality SiOx Thin Film Deposition: Exploring New Chemical Pathways for Polymerization and Surface Treatment
No full textPlasma Enhanced Chemical Vapor Deposition (PECVD) is well proven method for depositing high quality barrier films and membranes based on SiOx. Usually, the deposition starts with volatile monomer containing Si and oxygen, either hexamethyldisiloxane (HDMSO) or tetraethyl orthosilicate (TEOS), which are the precursors for polymerization of thin film. To eliminate excessive carbon and hydrogen, atomic oxygen is morphology and structure by densifying and cross linking the film layers. These two processes, polymerization and production of flux of oxygen atoms, are commenced in plasma or electrical gas discharge in monomer/oxygen mixture. Here we discuss whether it is possible to use the oxygen atoms in double role: (i) to control the deposited film properties and (ii) to initialize and control the polymerization process. Two monomers are tested, HDMSO and TEOS respectively, and deposited thin films are analyzed by X-ray Photoelectron Spectroscopy (XPS) and Fourier Transformed Infra-Red (FTIR) absorption spectroscopy
Targeting cancer cells by up-converting NaGd0.8Yb0.17Er0.03F4 nanoparticles
No full textIn current medical research, biological imaging holds an important position in diagnostics, as it allows visualization of cell morphology and the processes occurring within them. As a result, considerable attention has been directed towards the development of novel types of biomarkers, including up-converting nanoparticles (UCNP) optically active under near-infrared (NIR) radiation. Lanthanide-doped UCNPs offer advantages over currently used fluorophores, due to the absence of tissue autofluorescence, minimized local heating, non-bleaching, and stable response. In this work, biocompatible NaGd0.8Yb0.17Er0.03F4 UCNPs nanoparticles were synthesized through one-pot solvothermal processing with assistance of chitosan. Obtained nanoparticles were analyzed by X-ray powder diffraction (XRPD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) and photoluminescence (PL) spectroscopy. The findings confirmed crystallization of the cubic crystals with a good luminescence response. To assess the biological safety of their use, a cytotoxicity test was conducted. Additionally, nanoparticles were conjugated with anti-human CD44 antibodies labeled with fluorescein isothiocyanate (FITC) and incubated with HS-5 fibroblasts and oral squamous cell carcinoma OSCC cells. Scanning laser microscopy is used for in vitro imaging of labeled cells. Based on the colocation of the FITC and UCNPs signals, selective labeling of OSCC cells was verified
The influence of oxygen vacancies in ZnO/RuO2 crystal structure on the photoelectrocatalytic efficiency for hydrogen production
No full textRazvoj katalizatora za elektrohemijsku reakciju izdvajanja vodonika je od suštinskog značaja za unapređenje procesa elektrolize vode i prelazak ka čistim energetskim rešenjima. Iako su katalizatori iz platinske grupe metala najefikasniji, njihove ograničene rezerve i velika cena sprečavaju široku komercijalnu primenu. U okviru ovog rada razvijeni su katalizatori u kojima je rutenijum zamenjen pristupačnijim rutenijum-dioksidom, a njegova količina je smanjena upotrebom dostupnog i multi-funkcionalnog cink-oksida. Kompozit ZnO/RuO2 sintetisan je metodom mikrotalasnog procesiranja precipitata i termički modifikovan na dve temperature, 300 i 600C, kako bi se ispitao uticaj kiseoničnih vakancija na fotoelektrokatalitičku aktivnost u reakciji elektrolize vode. Stabilnost materijala određena je metodom TG/DTA dok su fazni sastav i defekti u strukturi određeni metodama rendgenske difrakcije na prahu (XRD) i fotoluminiscentne (PL) spektroskopije. Fotoelektrokatalitička aktivnost kompozita za reakciju izdvajanja vodonika ispitana je metodom linearne voltametrije u kiselom i baznom elektrolitu.The development of catalysts for the electrochemical reaction of hydrogen evolution is essential for the improvement of the water electrolysis process and the clean energy transition. Although catalysts from the platinum group are the most effective, their shortage and high-cost limit widespread commercial application. In this study, we developed catalysts in which ruthenium was replaced by more affordable ruthenium dioxide, and its amount was reduced by using abundant zinc oxide. The ZnO/RuO2 composite was prepared by microwave processing of precipitate and further thermally modified at 300 and 600 C, in order to examine the influence of oxygen vacancies on (photo)electrocatalytic activity in the water electrolysis reaction. Thermal stability of catalysts was determined by thermo-gravimetric/differential thermal analysis (TG/DTA) technique, while the phase composition and crystal defects were determined by X-ray powder diffraction (XRD) and photoluminescence (PL) spectroscopy, respectively. Electroand photoelectrocatalytic activity of the composite toward hydrogen evolution reaction was tested by linear voltammetry in acidic and alkaline electrolyte

The Study of Byzantine History in Belgrade before and after the First World War
No full textThe emergence of academically grounded Byzantine studies in the renewed Serbia at the beginning of the twentieth century–marked by the establishment of the Chair and Seminar for Byzantine Studies at the University of Belgrade in 1906–was connected with efforts to found a scholarly historiography in the restored state with the help of scholars educated at foreign universities. A decisive role in this process was played by Serbian students who had studied at the first Byzantine Studies Chair and Seminar of Professor Karl Krumbacher in Munich–Dragutin Anastasijević, Božidar Prokić, Filaret Granić, and others–who were active during the period of early internationalization of Byzantine studies, on the eve of and following the end of the First World War
