  Photonic device application of a self-driven MXene based nanocomposite

  Demirelli, Kadir; Dere, Ayşegül; Barım, Esra; Tuncer, Hülya; Yakuphanoğlu, Fahrettin

  MXene based ternary composite photonic device was fabricated and characterized for the detection of different illuminations. The single chain polymer-cobalt phthallocyanine (SCP-CoPc) carrying metallised pthalocyanine macro ring was used as a polymer for the preparation of ternary composite. The Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX) were used to differentiate MXene/ZnO/SCP-CoPc composite prepared. The presence of Ti, C, O, Zn and Co elements in the structure of the composite was confirmed by EDX. The electrical properties of planar interdigital coated MXene/ZnO/SCP-CoPc (1:1:1 by wt) were investigated for photovoltaic application. The photo-generated carriers contribute to the current flow, and the linear photoconductivity behaviour in current measurements with different illuminations such as 20, 40, 60, 80 and 100 mW/cm2 indicates the possible photo device use of MXene/ZnO/SCP-CoPc nanocomposite. The photocurrent increased from 20 mA/cm2 to 100 mA/cm2 with the light intensity at 0.5 V was tuned from 28 to 280 μA. The forbidden energy gap (Eg) value of the MXene/ZnO/SCP-CoPc ternary composite from optical measurements was found to be 2.36 eV. Experimental results showed that the presence of SCP-CoPc and ZnO (zinc oxide) in the ternary nanocomposite increased the ε' and ε" values of MXene. The ε′ and ε″ of the ternary composite is 13.0, 26217 at 1 kHz and room temperature, respectively. The current-time results suggest that MXene based ternary composite photonic device is a self driven photodevice as the device can detect light without any external voltage bias.

  Preparation and characterization of the highly efficient tetraphenylimidazole substituted Phthalocyanine/ZnO composite and investigation of its effect on the photocatalytic degradation of Rhodamine B and 2,4,6-trichlorophenol

  Growing concerns about industrial waste-induced environmental degradation have driven research towards sustainable solutions. Photocatalytic degradation, fueled by light and avoiding harmful chemicals, offers a promising avenue due to its minimal environmental impact. ZnO, TiO₂, and their derivatives are particularly effective and widely studied photocatalysts. This study aims to prepare new composite materials bearing phthalocyanine and investigate the photocatalytic properties on the degradation of Rhodamine B dye and 2,4,6-trichlorophenol (TCP) as the model compounds. In the initial step, ZnO materials were synthesized using the solvothermal method. Subsequently, a novel Zn(II) complex, including peripherally tetra phenyl imidazole substituted phthalocyanine, was successfully prepared. The composite catalysts were prepared from ZnO materials produced with the tetraphenyl imidazole phthalocyanine Zn(II) complex, called TFI-Zn. The were characterized using instrumental techniques. The photocatalytic characteristics of the composite materials developed were further examined under varying quantities of catalyst and Rhodamine B, variable pH conditions, and varying intensities of UV-A light. In addition, the reusability of the catalyst was investigated. With the new composite photocatalyst prepared within the scope of this study, 98% degradation efficiency and 8.0 × 10−4 min−1 degradation rate was obtained on Rhodamine B solution in 40 min. The newly developed photocatalyst displayed remarkable catalytic activity that remained virtually unchanged for five consecutive cycles, indicating excellent reusability and operational stability. The photocatalytic degradation performance of ZnO-TFI-Zn (1) was also examined on TCP and 90% degradation activity was obtained at the end of 80 min.

  Development of new generation cakes fortified with zinc oxide nanoparticles

  Kaplan Ince, Olcay; Aydogdu, Burcu; Ince, Muharrem

  This study aimed to develop new generation cakes that were fortified with calcined ZnO nanoparticles (CZnO), uncalcined ZnO nanoparticles (UCZnO), beads (B(CZnO)) synthesized by encapsulating the CZnO with sodium alginate (SA), and the beads (B(UCZnO)) synthesized by encapsulating the UCZnO with sodium alginate (SA) and investigated the zinc (Zn) release in fortified cakes in simulated body fluids (SBF). The present study represents a novel method for increasing intestinal absorption and bioavailability of dietary zinc with zinc nanoparticles for use in the preparation of Zn fortified cakes as a dietary supplement to compensate for zinc deficiency in humans. The results revealed that a rapid increase in the release time and rate in the SGF solution was noted in the UCZnO added cakes. It was attributed to increased intestinal absorption and bioavailability as a result of the ultra-small size of ZnO. Also, ZnO release kinetics in SBF was also studied and data were adjusted into different kinetic models involving zero-order, first-order, Higuchi, and Korsmeyer–Peppas models. The present investigation recommends adding UCZnO to the cakes to control and increase the release from the cakes.

  Synthesis and structural, electrical, optical, and gamma-ray attenuation properties of ZnO-multi-walled carbon nanotubes (MWCNT) composite separately incorporated with CdO, TiO2, and Fe2O3

  Basgoz, Oykum; Guler, Omer; Evin, Ertan; Yavuz, Cagdas; ALMisned, Ghada; Issa, Shams A.M.; Zakaly, Hesham M.H.; Tekin, H.O.

  In this study, Fe2O3, TiO2, and CdO semiconductor metal oxides were separately incorporated into the ZnO-MWCNT composite at different weight percentages. Accordingly, several experimental analyses on electrical, optical, and radiation shielding characteristics of coupled semiconductor metal oxides nanocomposites were performed to determine their monotonic impact on the investigated material properties. Moreover, gamma-ray shielding properties of these novel materials were determined using MCNPX general-purpose Monte Carlo code. At 5% oxide addition, the maximum electrical conductivity was found in all groups for all temperatures. Moreover, 5% oxide reinforcement resulted in the maximum reflection characteristics in all groups. Among the CdO doped materials, the CZnOCd5 sample exhibits the highest electrical conductivity behaviour at room and high temperatures. The Eg value calculated for the CZnOCd5 sample was 3.284 eV. The CZnOCd2.5 and CZnOCd5 samples had the greatest Eg values when compared to the pure sample and the samples from other groups. The CZnOCd5 sample has the highest reflectance value in the CZnOCd group's reflectance graph. On the other hand, the maximum gamma-ray attenuation properties were reported for CZnOCd5 sample. Among the analysed samples, the CZnOCd5 sample's characteristics provide a preliminary motivation for a more comprehensive analysis of this material and assessment of potential radiation protection applications.
