The purpose of this research is to facilitate the use of starch paste in the restoration of paper works. Especially the works where ink and colors used are not sensitive to water. In this research, starch paste with a ratio of 3 to 1 (3 parts paste and 1 part water) was used. The use of starch paste increased the pH of the samples coated with this paste compared to the control samples without paste. The samples coated with starch paste had the lowest pH after moist-heat aging compared to other samples. The samples coated with starch paste showed the lowest amount of color changes (∆E) after moist-heat aging and light aging, respectively. The use of starch paste increased the tensile strength of the samples. After light aging and moist heat aging, the tensile strength of the samples decreased compared to the previous stage, but the tensile strength of the samples coated with starch paste increased compared to the control samples without paste. The results of the adhesion resistance test of the samples showed that the amount of adhesion of the samples decreased to a greater extent after moist-heat aging compared to light aging.
Polylactic Acid (PLA) is a thermoplastic biodegradable material produced from renewable resources like corn starch or sugar cane. It is generally considered safe for use in food, and its production using existing manufacturing processes makes it cost-efficient. PLA is a hydrophobic and crystalline polymer. PLA membrane was fabricated using Polyethylene Glycol (PEG) and N-Methyl-2-Pyrrolidone (NMP) by the phase inversion method using Tween 60 as an effective emulsifier additive. Tween 60 is an ethoxylated sorbitan ester-based fatty acid (stearic acid). The prepared PLA membrane structure and morphology were studied by Scanning Electron Microscopy (SEM), and the performance of the prepared membrane was evaluated by measuring porosity, pore size, and tensile strength. The tensile test confirmed that PLA membranes demonstrate allowable mechanical properties. After completing this observation, it was found that some amount of Tween 60 increased the water content pore size without disturbing polymer chain entanglement and enhanced water permeability through the membranes.
This paper investigates the Nano Composite Gel Polymer Electrolyte (NCGPEs) based on nanofillers Zirconium dioxide (ZrO2), Polyacrylonitrile (PAN), and Ammonium triflate or Ammonium trifluoro methane sulfonate (NH4CF3SO4) doped at various wt% ratios prepared with the help of the solution casting technique. The better amorphous nature observed for the 70 PAN:30 NH4CF3SO4 composition with the addition of 1-4 wt% of ZrO2 nanofillers and structural complexation studies of NCGPEs were confirmed by the X-ray Diffraction (XRD) technique. The microstructural studies and particle size can be revealed by the Scanning Electron Microscopy (SEM) technique. DC conductivity studies reveal the ionic conductivity performance on the effect of temperature and composition wt% of nanopowder. The ionic conductivity studies were observed for 70PAN:30NH4CF3SO4 with nanopowder ZrO2 concentrations ranging from 1-4 wt%. The sample containing 3% ZrO2 exhibits the highest conductivity order of 4.20 x 10-4 S cm-1 at room temperature (303K) and 4.65 x 10-3 S cm-1 at 373 K. The cell parameters like open-circuit voltage, short-circuit current, energy density, and power density were perfectly determined, which were useful to explain electrochemical cell behavior.
This study focuses on the preparation and characterization of the [Fe III(EDTA)H2O]- complex at low temperatures, with the objective of identifying heme-like water-soluble properties. The research explores the potential health benefits of this complex, extracted from natural sources, in enhancing immunity and leveraging its heme-like properties. The prepared water-soluble complex was subjected to a comprehensive characterization process utilizing various analytical techniques, including UV-Visible spectroscopy, Powder X-ray Diffraction (PXRD), and Fourier-Transform Infrared (FT-IR) spectroscopy. The characterization results revealed the compound's structural properties, optical behavior, and molecular interactions, providing valuable insights for its potential applications in various fields. The complex was also evaluated for its photocatalysis capabilities. The results of the study indicate that the prepared [Fe III(EDTA)H2O]- complex exhibits structural and spectral similarities to Hemin Iron(III) complex. This suggests that the [Fe III(EDTA)H2O]- complex could potentially have similar biological or catalytic properties to the Hemin Iron(III) complex, opening up new avenues for research and applications. This research lays the foundation for further investigations into the health benefits and potential applications of this heme-like water-soluble complex in immunology and photocatalysis.
