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 ›
