Few Layer Graphene

We have developed a flexible planar asymmetric supercapacitor demonstrating high energy storage capability which can be utilized to power various flexible and wearable electronic devices. Locally available cheap source of biomass such as banana peel was utilized for synthesizing carbonaceous materials like few-layer graphene and activated carbon for electrode material application. Few-layer graphene was synthesized by heating banana peel at high temperature under inert atmosphere followed by crushing with mortar-pestle. Activated carbon was synthesized by heating banana peel impregnated with KOH at high temperature in absence of air. The device was fabricated by using low-cost screen printing technique to print current collectors followed by deposition of active electrode materials and sandwiching filter paper soaked in gel electrolyte in between the electrodes. The fabricated devices showed high areal capacitance of 88.31mF/cm2 at 10 mV/s scan rate. The device also showed satisfactory performance under multiple electronic cycling (100 cycles) and bending conditions. The device can be fabricated on a large scale using low-cost screen printing technique and cheaply available biomass which can be further utilized for developing emerging flexible electronics.

Micro-encapsulated pigments were formulated into biodegradable printing pastes and their properties were analyzed. The pigment was used as the core material and polylactic-based biodegradable thickener was used as the wall-former. Cotton/polyester blend fabric was printed with micro-encapsulated pigment using screen-printing technique without dispersing agents, penetrating agents, leveling agents or other auxiliaries. Micro-encapsulated pigment has been characterized in terms of average particle size and size distribution, morphological structure and elemental composition using scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). The variations in viscosity and paste stability were observed upon storing over 7 days at ambient temperature. For permanence, the micro-encapsulation process afforded better colorfastness properties against light, washing, rubbing, and perspiration.

Photoelectric Properties of Screen-Printed Al-Doped ZnO Films The potential of cheap semiconductor materials in the area of solar energy use is illustrated by the example of zinc oxide (pure and Al-doped in various concentrations). Under investigation was the electric conductivity and photoelectric properties of ZnO thin films. The samples were prepared using screen-printing technique. The results of measurements point to non-linear relationships between Al concentration, photosensitivity and electrical conductivity of thin ZnO films. Optimal Al concentration for practical use of ZnO in photovoltaic devices is found to be ~ 1%. The experimental methods, technologies and results described in the paper could be used for further investigations in this area.

Lowering the operating temperature of solid oxide fuel cells (SOFCs) is crucial to make this technology commercially viable. In this context, the electrode efficiency at low temperatures could be greatly enhanced by microstructural design at the nanoscale. This work describes alternative microstructural approaches to improve the electrochemical efficiency of the BaCo0.4Fe0.4Zr0.1Y0.1O3-δ (BCFZY) cathode. Different electrodes architectures are prepared in a single step by a cost-effective and scalable spray-pyrolysis deposition method. The microstructure and electrochemical efficiency are compared with those fabricated from ceramic powders and screen-printing technique. A complete structural, morphological and electrochemical characterization of the electrodes is carried out. Reduced values of area specific resistance are achieved for the nanostructured cathodes, i.e., 0.067 Ω·cm2 at 600 °C, compared to 0.520 Ω·cm2 for the same cathode obtained by screen-printing. An anode supported cell with nanostructured BCFZY cathode generates a peak power density of 1 W·cm−2 at 600 °C.
