  • Segmented strip design for a magnetostriction sensor (MsS) using amorphous material for long range inspection of defects and bends in pipes at high temperatures
    Patent number: 10073065
    Abstract: The invention relates to a continuous monitoring system which will monitor the pipes without the need of shutting down of the plants. The major issues in designing such a system using magnetostriction as per prior art is the loss of magnetization of the permanent magnets used to provide the magnetic bias and also the disbonding of interfaced adhesives with which the magnetostrictive ribbons are bonded at high temperatures. The invention identifies a novel sensor which can be taken up to high temperatures without any loss of signal strength, this is achieved by generating guided waves using a special amorphous magnetostrictive ribbons. L(0, 2) mode waves are generated using these ribbons to monitor pipes working at high temperatures as per the invention.

  • Detection of quantity of water flow using quantum clusters
    Patent number: 10041925
    Abstract: The preparation of silver quantum clusters embedded in organic-templated-boehmite-nanoarchitecture (OTBN) and its use as a sensor for quantity of water flow measured by change of color in visible light upon flow of contaminated water have been provided. Silver quantum clusters-embedded OTBN are highly luminescent. Since the quantum clusters are embedded in the matrix, they are highly stable over a long period of time. The composition described here is utilized in the form of a device for ‘visible/ultraviolet light color change-based detection’ upon passage of water through a water purification device. Upon interaction with ions present in water, luminescent silver clusters undergo chemical transformation to Ag2S nanoparticles. The transformation is reflected in the form of visible color change (from pink to black) and luminescence quenching (from red emission to negligible luminescence).

  • Multilayer organic-templated-boehmite-nanoarchitecture for water purification
    Patent number: 10035131
    Abstract: An adsorbent composition comprising a nanoscale shell of metal oxide or hydroxide on an organic-templated-boehmite-nanoarchitecture (OTBN) is provided. The nanoscale shell is prepared by impregnating OTBN with a metal or a non-metal ion, followed by in-situ hydrolysis of the deposited ion on the OTBN surface. The thickness of the shell is less than about 3 nm, which is less than the size of OTBN core. The number of layers of the shell is flexible, thereby leading to a multi-layer nanoscale hybrid composition. The adsorbent composition is capable of removing inorganic anions such as fluoride from water, with an increased adsorption capacity.
