We use high voltage electron beam lithography followed by electroplating to define small metal features on semiconductor substrates. These have been used to form high resolution etch masks, dense nanomagnet arrays, and highly anisotropic metal nanostructures. To reproducibly obtain uniform arrays of such structures, we have developed an end-point detection technique, which is based on in situ o...
In our experiments, we use different photoresists for proton beam writing and mold fabrication. We have fabricated Ni mold with structures down to 500 nm. We first use a fine focused proton beam to expose different photoresists, Polymethyl Methacrylate (PMMA), AR-P 3250 and ma-N 2410. After development and nickel sulfamate electroplating, the structures were faithfully transferred from the phot...
A cost-effective and reliable Ni-Au contact on nanostructured Bi2Te3-based alloys for a solar thermoelectric generator (STEG) is reported. The use of MPS SAMs creates a strong covalent binding and more nucleation sites with even distribution for electroplating contact electrodes on nanostructured thermoelectric materials. A reliable high-performance flat-panel STEG can be obtained by using this...
Background: Cr (VI) is a highly toxic and carcinogenic contaminant and that are used in the steel industry and other chemical industries such as the leather industry, pigment production, electroplating of metals and the production of anticorrosive compounds. Its waste enters the environment and subsequently enters the water and food sources. Therefore, in order to protect the environment as wel...
We introduce silk textile-based water-splitting electrodes that can significantly increase the electrocatalytic performance for both HER and OER by a carbonization/interfacial assembly-driven electroplating approach.
Heavy metals discharged from various industries like electroplating, leather tanning, paint, textile and dying units are the primary cause of water pollution [1]. They pose serious threats to public health and environment due to their high toxicity, bio accumulative and non-biodegradable behavior [1,2]. Therefore, Water purification is emerging as a critical need for the researchers owing to th...
Introduction: One of the heavy metals is chromium which is used in trivalent and Hexavalent oxidation state in industries such as, glass, ceramic, tannery, leather especially in electroplating industries. Hexavalent Chromium has proven several health hazards such as a carcinogen. The aim of this study was to investigate the efficiency of Melia azedarach ash in the removal of hexavalent chromium...
