Date Palm Silver Nanoparticles

The root hairs of the date palm from Saudi Arabia goes to Korea where they extract the phytochemicals. The extract is used to produce silver nanoparticles that are effective against bacteria, fungi and cancerous growth.

Copper Oxide Nanoparticles: synthesis with neem leaf extract

Producing nanomaterials, using plant extracts, is emerging as a promising approach to create metal oxide nanoparticles with potential applications in optoelectronics, nanosensors, nanodevices, nanoelectronics, information storage, and catalysis. Among the various metal oxide nanoparticles, copper nanoparticles are of great interest, because of their low cost of preparation and excellent physical and chemical properties. Copper nanoparticles… Read More ›

Fluorescent tool for cyanide sensing

Mumbai University researchers come up with cost effective way to monitor cyanide in water. A call for action to environmental entrepreneurs.

Solar Cells with Nano-Needles: Flexible and Efficient

The efficiency of solar cells is like a jigsaw puzzle. All the pieces are disparate. Though the solution depends on every single piece available, the progress depends on some key pieces. The structure and arrangement of the nanoparticles is one such key piece in the puzzle that can lead us to quicker solutions. Rakesh Sonker,… Read More ›

Diagnosing Depression: Egged on by EEG

Electroencephalograms record brain activity non-invasively and have been used to study depression since the 1930s. Yet depression continues to strike celebrity and commoner alike. A timely diagnosis, could, perhaps, save lives. Generally, specialists rely on time consuming questionnaires and sessions. Now, with colleagues from Singapore, Malaysia and the US,  D P Subha from the NIT… Read More ›

Gold Nanozyme to Detect Glucose

A highly sensitive sensor kit that can detect glucose in serum, tears, saliva…

Nanocomposite to Detox Wastewater

Removing heavy metals through sorption High amounts of metallic elements, such as lead, cadmium and copper, make water toxic. Sequestration of these elements from water is the only possible way to make water safe for use. Recently, Rais Ahmad and Anam Mirza from the Aligarh Muslim University synthesised a chitosan-iron oxide nanocomposite to remove heavy… Read More ›

Filling Carbon Nanotubes with metal nanowires

Ashna Bajpai and team from IISER Pune makes metal nanowires and covers them with a layer of carbon

Removing Toxic Dye from Water

Using Ceiba Pentandra Seeds Toxic dyes released into water bodies by textile industries are a major environmental concern. One could use chemical precipitation, ion exchange, membrane filtration, coagulation, reverse osmosis, liquid–liquid extraction, ozonation, electrochemical oxidation, and electrodialysis to remove dyes from effluents. But they are expensive. Adsorption, on the other hand, is highly effective and… Read More ›
