Other problems cited include an absence of information about groups working in the sector and the domestic industry's reluctance to manufacture large quantities of nanomaterials proven to have commercial application.
India has more than 30 industries and 50 institutes engaged in nanotech research and development, with most efforts focusing on chip design, nanomedicine and nanomaterials. Nanotechnology has potential uses in drug delivery, diagnostic kits, improved water filters and sensors, and reducing pollution from vehicles.
Since the launch of a US$250 million five-year national nanotech mission in 2007, India has seen a rise in the number of scientists working in the field and research publications, said V. S. Ramamurthy, former secretary of India's Department of Science and Technology and currently on the board of the Indian Institute of Technology in Delhi.
The national mission aims to make India a global hub by setting up clusters of research groups in the sector (see "India looks to nanotechnology to boost agriculture" (www.scidev.net/en/news/india-looks-to-nanotechnology-to-boost-agriculture.html) and "Preparing for take-off: Indian Nanotechnology" (www.scidev.net/en/features/preparing-for-takeoff-indian-nanotechnology.html)).
But there has been no corresponding increase in nanotech products in the marketplace. India needs to work on turning its laboratory research findings into commercially viable products that are either globally competitive or locally relevant, said Ramamurthy. "We need to evolve synergies and strategies so that the strengths in the labs are converted into strengths in the marketplace," he said.
C. N. R. Rao, chairman of the Scientific Advisory Committee to India's Prime Minister, suggested Indian scientists and industry should work on 'hot' emerging technologies with tremendous potential, which are attracting the interest of researchers worldwide. These include use of nano-scale particles of graphene, a one atom thick layer of carbon molecules that form the basic structure of graphites. The material is one of the strongest known and has uses in microelectronics and tremendous capacity to absorb the greenhouse gas carbon dioxide.
Rao also suggested India should work on 'nano' forms of currently known materials that can throw up exciting applications.Delegates at the meeting also pointed out that India does not have a systematic information base on all scientists.
Ajay Sood, professor of physics at the Indian Institute of Science in Bangalore said, "An information map on interested industry and academics is very much needed; an information platform that is easily accessible and can be updated."

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
