By doping zinc oxide with other metals, Chennai scientists make dye sensitised solar cells a more feasible and less costly energy harvester.
Acids eat into cement, making concrete weaker. MNIT, Jaipur overcomes the problem with crumbs from waste tyres.
Researchers from SASTRA University and IIT Delhi have come up with a textile that can protect you from UV radiations. The fabric can also warn you of the presence of poisonous gases.
A R Mohanti and Sneha Singh from IIT Kharagpur gives tips on reducing the aerodynamic noise of the air-conditioning units in vehicles.
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.
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 ›
Mumbai University researchers come up with cost effective way to monitor cyanide in water. A call for action to environmental entrepreneurs.
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 ›
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 ›
