  • The Role of Collagen Addition on the Mechanical Properties of PVA/Chitosan Composite Nanofiber Membranes as Wound Dressing Materials
    The increasing need for renewable natural resources in various applications such as in the medical field, a study has been conducted on using chitosan and collagen to prepare composite nanofiber membranes as wound dressing materials. The materials used were polyvinyl alcohol (PVA) solution of 10%, chitosan solution of 2%, and collagen solution added at concentrations of 2%, 4%, and 8%. The composite nanofiber membranes are manufactured by using an electrospinning technique with various PVA-chitosan-collagen ratios of 8:2:0, 8:2:2, 8:2:4, and 8:2:8. The names of the samples are P/Ch/C0, P/Ch/C2, P/Ch/C4, and P/Ch/C8, respectively. The membranes were characterized by FTIR, SEM, DMA (tensile strength), and swelling tests. The results indicated that collagen addition decreases the maximum tensile strength (UTS) and softens the membranes. The best membrane obtained was P/Ch/C2, with the average diameter and length being 145.55±8.64 nm and 24.19±1.03 µm respectively. Their mechanical properties are UTS of 1.52 MPa, Young’s modulus (E) of 39.67 MPa, a percentage of elongation at break (BE) of 19.16%, and a percentage of swelling of 362%. It fulfills the standard of medical materials for a wound dressing application.

  • Preface to the Proceedings of the International Conference on Physics and Technology of Advanced Materials (ICPTAM) 2024 in conjunction with 8th Nanoscience and Nanotechnology Symposium (NNS)

  • The Effect of Substrate Temperature on CNT Deposition with Ni Catalyst as Precursor
    The effect of temperature substrat on the growth of carbon nanotubes (CNTs) with a Ni catalyst precursor were studied, where the CNTs were grown by HWC in plasma-VHF-PECVD method. The Ni catalyst was grown on a glass substrate utilizing the evaporation method, with parameters such as deposition time 50 seconds, annealing temperature 500 °C for 4.5 hours. Morphological characterization of the Ni catalyst was done using a Scanning Electron Microscope (SEM). Subsequently, the Ni catalyst served as a growth precursor for CNTs with parameters such as CH4 gas flow rate of 80 sccm and a pressure of 300 mTorr for 60 minutes. Substrate temperature was varied at 250, 275 and 300 °C. Characterization of the CNT thin layer using SEM, and Raman spectroscopy produced ID/IG values of 0.94, 1.14, and 1.06, respectively. From the comparison of the intensity ratio of the D-band and G-band, the optimum temperature for CNT growth was 250 °C.

  • Green synthesizes of Silver Nanoparticles (AgNP) from Henna Leaf Extract (Lawsonia Inermis) and Its Chemical and Physical Properties as Photo-sensitizers in The DSSC
    To substitute an expensive inorganic dye, we green synthesized silver nanoparticles (AgNP) from Henna leaf extract as photosensitizers in DSSC. Henna dye was macerated for 24 hours using ethanol and filtered. To synthesize AgNPs, 10 ml of Henna dye was added to 90 ml of AgNO3 solution (0.01 M, 0.05 M, and 0.3 M) and stirred. The FTIR analysis of the Henna dye showed three main Lawsone functional groups (O-H phenol, C=O, and C=C). As for AgNP, the new peak with high intensity emerged at a frequency of 1381 cm−1, indicating the existence of Ag. The FTIR results upheld by the diffractogram of the AgNP that showed the crystalline peak at the 2θ position of (29.5, 32.6, 38.0, and 44.1)° associated with Miller indices of [210],[122],[111], and [200], respectively. The evaporation process increases the crystallinity of the AgNP. The nanoparticle size increased from 124.8 nm to 189.1 nm with the AgNO3 concentration from 0.01M to 0.1M characterized by PSA. From the Henna dye absorbance spectrum, the peak at (238 and 370) nm originated from Lawsone molecules. AgNP showed the absorbance peak at 420 nm and 430 nm for unevaporated and evaporated Henna, respectively. These peaks’ intensity increased with the irradiation time of up to 72 hours, associated with the shift of the plasmon surface resonance to the lower energy. The energy gap ranges from (2.08-2.09) eV and (2.58-3.69) eV for Henna dye and AgNP, respectively. It is in the range for light harvester material in DSSC.
