  The Frequency-Dependent Electrical Properties and Fabrication of Diode

  Sevgili, Omer; Orak, Ikram; Özel, Sultan Suleyman; Özel, Faruk

  The fabrication of Al/NiO/p-Si Schottky diode (SD) was formed using a thermal evaporation system. The structural analyze of NiO using an interfacial layer was conducted using a Scanning Electron Microscope (SEM) and the SEM cross-section revealed a thickness of 0.0345 mu m for NiO interfacial layer. The capacitance-voltage (C-V) and conductance-voltage (G/omega-V) measurements of the fabricated SD were performed in the 50 kHz to 5 MHz frequency range and in the-3 V to +3 V range. The Nicollian-Brews method was employed to calculate the series resistance (Rs), while the high-low frequency capacitance method (CHF-CLF) was used to calculate the surface states (Nss). The value of the Nss was determined to be in the order of 1012 eV-1cm-2. These findings suggest that NiO is a promising alternative to conventional insulating layers in electronic devices.

  Hot injection synthesis of metal-doped Ag2S nanocrystals: A novel multifunctional approach for cancer therapy, antibacterial strategies, and antioxidant defense

  ULUSU, Funda; OZEL, Sultan Suleyman; Sarilmaz, Adem; ULUSU, Yakup

  This pioneering study presents the synthesis and comprehensive evaluation of bare and metal-doped Ag₂S nanocrystals (NCs) as multifunctional agents with potential applications in antibacterial, antioxidant, and anticancer therapies. The incorporation of manganese, nickel, cobalt, and zinc into Ag₂S NCs resulted in a notable enhancement of their bioactivity, representing a novel approach in nanomaterial design. The antibacterial assessments revealed that Mn:Ag₂S NCs were the most potent candidate, exhibiting exceptional activity against S. aureus and E. coli, with the lowest MIC values recorded at 1.28 mg/mL and 1.08 mg/mL, respectively. The antioxidant studies demonstrated that the Mn:Ag₂S NCs exhibited remarkable free radical scavenging and ferric reducing capacities, with the lowest IC50 values (22.69 µg/mL for DPPH and 61.31 µg/mL for FRAP) underscoring their potential to mitigate oxidative stress. Importantly, cytotoxicity assays revealed that Ni:Ag₂S and Mn:Ag₂S nanocrystals selectively inhibited the proliferation of human colon cancer cells (HT-29), achieving IC50 values of 61.51 µg/mL and 90.12 µg/mL, respectively. Furthermore, these NCs demonstrate reduced toxicity towards mouse fibroblast cells (L929). This selective cytotoxicity indicates the potential of these agents in targeted cancer therapies, thereby reducing damage to healthy tissues. To the best of our knowledge, this is the first study to systematically explore the synergistic effects of metal doping on the multifunctional properties of Ag₂S NCs. These findings provide a robust basis for further in vivo studies and offer new avenues for the development of safe and effective nanomaterials in biomedical applications, particularly as antimicrobial, antioxidant, and anticancer agents.

  Investigation of the Effects of Low-Temperature Thermal Treatment Applied to Graphite in Spent Lithium-Ion Anode Recycling

  Kara, Adem; Temur, Hakan

  As the use of lithium-ion batteries (LIB) increases rapidly, recovery of graphite, the main component of the anode, from spent batteries has become important from environmental and economic perspectives. In this study, an acid leaching step followed by thermal treatment under partial atmosphere at a relatively low calcination temperature was investigated to recover graphite from spent lithium-ion batteries. The molecular and chemical structures of the recovered graphite in all spent anode samples were investigated using FTIR, ICP-MS, XRD, SEM–EDX and TEM–EDX. It was observed that organic impurities and volatile components were largely removed after acid leaching and thermal treatment at 750 °C. In addition, it was observed that graphite layers were rearranged and the distance between the layers decreased under the effect of thermal treatment. Partial atmosphere calcination at 750 °C can be considered as a feasible method for graphite recovery, offering energy efficiency and scalability. However, in an efficient calcination, it is necessary to maintain controlled oxygen levels to prevent excessive graphite loss and to perform preliminary acid leaching to reduce metal impurities. In order to best recycle graphite in waste lithium-ion anode recovery, a balance must be achieved between temperature, energy efficiency and material recovery. Considering this balance, a calcination temperature of 750 °C appears to be preferable for recycling.

  Physical, chemical and thermal characterization of bacterial nanocellulose produced using sugar beet molasses by Komagataeibacter sp. SB2569

  Kara, Adem; Bayram, Sinan

  Bacterial nanocellulose (BNC) is a biopolymer synthesized by bacteria utilizing various carbon sources. The biocompatible and biodegradable nature of BNC offers considerable advantages for its application in fields such as medicine, biomedical engineering, cosmetics, food, nanocomposites, and organoelectronics. Nevertheless, the high production costs necessitate the development of more cost-effective and efficient BNC production methodologies. This study aimed to produce BNC utilizing cost-effective sugar beet molasses. To achieve this, bacteria isolated from various vinegar samples were assessed, revealing that the BNC production potential of these isolates ranged from 2.09 to 3.21 g L⁻1. The 16S rDNA gene of the strain with the highest BNC yield was amplified and sequenced, and it was subsequently deposited in the GenBank database as Komagataeibacter sp. SB2569, with the accession number PV231799.1. XRD analysis revealed characteristic diffraction peaks at 14.8°, 16.5°, 22.6°, and 34.5°, confirming the cellulose 1β crystalline structure and high crystallinity of the synthesized BNC. FTIR analysis exhibited characteristic absorption bandsthat, confirming the presence of β-1,4-glycosidic linkages and the cellulose I structure of BNC. TGA analysis showed an initial weight loss of ~ 5% between 0–100 °C, a major degradation of ~ 75% occurring at 220–350 °C with a maximum decomposition rate at 343 °C, and a residual mass of approximately 10–20% remaining above 600 °C. The findings indicate that the Komagataeibacter sp. SB2569 strain holds significant potential for BNC production using low-cost carbon sources.

  Multidimensional characterization of graphite anode degradation in used lithium-ion batteries under real-life conditions

  Temur, Hakan; Kara, Adem

  The degradation of graphite anodes in lithium-ion batteries remains a critical barrier to extending cycle life and enabling efficient recycling. This study employs a multi-technique approach combining XRD, FTIR, SEM-EDS, ICP-MS, and XPS to investigate degradation mechanisms in graphite anodes recovered from commercial spent mobile phone batteries. While unused reference anodes show no significant degradation, spent anodes exhibit surface cracks, porous networks, heterogeneous SEI growth, and pronounced oxygen/fluorine accumulation. FTIR and XRD confirm increased LiF and Li2CO3 formation, indicating electrolyte decomposition and structural breakdown. ICP-MS reveals transition metal migration (Co, Ni, Mn) and current collector corrosion (Cu, Al), which correlate with degradation severity. Surface-sensitive XPS analysis further resolves a progressive degradation pathway: from limited SEI formation in low-degradation samples, through concurrent corrosion and metal crossover in medium-degradation samples, to extensive LiF-rich SEI accumulation in the most degraded samples. These findings are consistent with a self-accelerating chain-reaction mechanism wherein electrolyte decomposition, metal migration, and corrosion synergistically accelerate capacity fade. This study proposes a mechanistic framework for understanding heterogeneous degradation in real-world spent batteries and offers a practical, multi-technique diagnostic tool for recycling and second-life applications.

  CMTS: An inorganic hole-transport material for efficient and stable perovskite solar cells through surface defect passivation

  Sari, Fahriye; Ozel, Sultan Suleyman; Ozel, Faruk; Kus, Mahmut; Wilton, Richard Hall

  A major challenge in PSCs lies in the carrier transport losses induced by band misalignment and elevated series resistance, which adversely impact the fill factor and device stability, ultimately restricting the overall power conversion efficiency. Due to their tunable band gaps, low fabrication cost, strong light-harvesting capability, adequate carrier lifetime, chemical stability, and environmentally benign nature, chalcogenide perovskites have emerged as highly promising materials for optoelectronic applications. In this study, the quaternary semiconductor nanostructure Cu2MnSnS4 (CMTS) was synthesized via a simple and cost-effective hot-injection method and investigated as an alternative inorganic hole transport layer (HTL) candidate. Indium tin oxide-based perovskite solar cells without any metal oxide interlayer achieved a remarkable PCE of 9.87% and retained more than 92% of their initial efficiency after 720 hours, demonstrating enhanced stability. These findings highlight the critical role of cation–anion interactions in improving device stability and underscore the importance of developing innovative, low-cost, and efficient inorganic HTL materials for the commercial advancement of perovskite solar cells.
