Mercury & Silver Detection

Technical Description The present invention relates to an electrochemical detection of mercury (Hg²+) and silver (Ag+) ions based on single stranded deoxyribonucleic acid functionalized multi-walled carbon nanotube (ssDNA:MWNT) matrix on gold electrode using ethylenediamine (EDA) and Dcysteine. Problems Addressed Expensive…

Biocompatible Coating For Implants

Technical Description The present invention relates to a biopolymer coating for metallic implants comprising of lignin esters, styrene and hydroxyapatite with improved adhesion strength, anti-oxidant property, and antimicrobial property. Problems Addressed Expensive Toxicity Weak Bonding Strength Non-biodegradable Inefficient Coating Lack…

Modular MFC System

Technical Description The technology relates to a multi-modular microbial fuel cell (MFC) that efficiently generates power as well as treats wastewater. Problems Addressed Expensive Inefficient COD Removal Low-power Generation Additional Components Needed Low-performance Bulky Systems Tech Features Cost-effective Sewage Wastewater…

High-Performance Varistor

Technical Description The invention describes a method for developing highperformance ZnO varistors with improved composition and CaO additives. It utilizes doped nanopowders from specific zinc, calcium, cobalt, manganese, and aluminium salts mixed with bismuth. Problems Addressed Carcinogenicity Limited Commercial Viability…

Water Purification System

Technical Description The present invention relates to a triple slope solar still to produce distilled water using solar energy with zero carbon emission for drinking purposes by adding some essential minerals. Problems Addressed Expensive Carbon Footprint Non-scalable Complicated System Low…

Off The Shelf MPPT Controller

Technical Description This invention is a PV maximum power point tracking system that repurposes standard switching regulator controller ICs to regulate the PV module voltage directly at VMPP. The control loop senses input side PV voltage instead of the usual…

Improved Fifth Wheel Coupling

Technical Description This invention is a modified fifth wheel coupling for prime mover–semitrailer combinations that reduces turning off tracking while keeping axle load distribution within safe traction limits. The mechanism reconfigures the coupling geometry so the trailer path tightens in…

Electrospun-Based Biosensor

Technical Description The invention involves a fabrication method for a biosensing device using an n-type transparent semiconducting thin film created via an economical electrospinning technique to analyze mammalian cell behavior in vitro. Problems Addressed Lack of Cell Sensing Limited Reproducibility…
