  Responsibilities :Assisting Students in Advanced Material Processing and Hydro & Electro-Mech. Systems Course.Research Works:1.Design & Construction of Electrospinning Machine* Electrospinning was carried out with a rotating collector drum and spinneret having a linear movement along the axis of the cylindrical collector autonomously controlled by limit switches* The whole system is autonomously controlled with an Arduino and optical sensors. Servo motors used for lateral movement of syringe and the injection of solution is controlled by hydraulic2. Nano Fiber Fabrication and Water Desalination*Fabrication of Nano Fiber membrane with PVDF-HFP DMF/DMAc and Acetone* Applying high voltage (up to 30kV) with very less current with different rate of pumping of the solution causes the nano fibers to form* Membrane was set inside a 3D printed chamber & heated seawater was circulated through one side and cold freshwater through the other side* Membrane restricts the salt and allows the freshwater vapor to penetrate through the membrane* Checking Fiber property before and after desalination under SEM, AFM, DSC, XRD, EDS, FTIR3. Piezo Sensitive Fiber Production & Energy Harvesting* Two comb like plastic pattern was cut using laser cutter and conductive pattern achieved through Gold Sputtering done on a Kapton tape* Later on, comb like pattern was drawn on a copper sheet using CNC Machine and dipped into acid solution to achieve conductive pattern* Piezo sensitive polymer was electrospun on the pattern to produce nano fiber membrane on it* By stretching the tape, potential amount of voltage generated from the membrane5. Fracture Propagation and Toughness Analysis of 3D printed Composite Structure* Designing structure with polymer materials adding roughness to the blocks and flexibility to the matrix* 3D print the designed model and place in a tensile and 3-point bending stage to analyze crack propagation and analyze under 3D microscope Show less
