In India, as in the rest of the world, biological macromolecular crystallography is now considered as an integral part of modern biology. This has happened only comparatively recently. The widespread practice of macromolecular crystallography is also a comparatively recent phenomenon in India. The development of the area in the country resulted from a substantially concerted effort. The structu...

Tailoring materials to obtain unique, or significantly enhanced material properties through rationally designed structures rather than chemical constituents is principle of metamaterial concept, which leads to the realization of remarkable optical and mechanical properties. Inspired by the recent progress in electromagnetic and mechanical metamaterials, here we introduce the concept of ferroele...

As socie ty becomes more comfortable discussing genetics and its related ethics, a new technology is blossoming in the background. Nanotechnology may speak the same societal language as does genetics, in that both technological movements involve tiny science and large imagination. In a way, it is natural—and almost inevitable—that the genetic revolution and the nanotechnology revolution be comp...

In this work, we present new results about the non-enzymatic detection of lindane by using CuO-MnO2 hierarchical nano-microstructures. The linear range for the determination of lindane is up to 700 μM with a limit of detection of 4.8 nM, which is much lower than for other non-enzymatic lindane sensors.

Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical properties on the nanoscale.
