Abstract In recent years piezoelectric nanogenerators, due to their more durability in high dust or humidity are more attractive than triboelectric ones. So, increasing their outputs is the subject of much researches. I focused on electrodes of the acoustic nanofibers nanogenerators for the first time. Here, I introduced a new electrode that is cheaper and does not result in lower outputs. Here for the first time graphene spin-coated ink was used for polyacrylonitrile-based acoustic nanogenerator. The results of the tests compared with the in-situ synthesis of nickel nanoparticles on the layer and using graphene spin-coated screen ink and conductive tapes. Finally, producing sound by this graphene ink was done too.

Filtration Process

The natural rise-husk charcoal was made by burned in a furnace at 230 °C. Carboxylic group (-COOH) was functionalized onto the charcoal by using oxalic acid in situ process. Fourier Transform Infrared Spectroscopy (FTIR) and morphology by Scanning Electron Microscope (SEM) demonstrated that the COOH-group was successfully functionalized on the charcoal and the particles were porous. The COOH-activated charcoal was applied for liming effluent treatment through a filtration media. Eight environmental load parameters was determined by the standard method. The results were compared with the standard permissible limits set by Inland Surface Water-Bangladesh Standards (ISW–BDS-ECR, 1997). It has been observed that the rice husk based activated carbons dramatically reduce the pollutants to permissible level. The removal efficiency of pH, Electrical Conductivity (EC), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Biological Oxygen Demand in 5 days at 20 °C (BOD5), Chemical Oxygen demand (COD), Total Alkalinity, S2- from liming effluent up to 40.0%, 85.89%, 98.8%, 81.32%, 96.74%, 78.6%, 97.15% and 79.61% respectively. In conclusion, the liming effluent simply recycled by filtration process and can be used for industrial purpose.
