New memory device to boost miniaturization of digital gizmos 

Sunderarajan Padmanabhan

New Delhi: Scientists at Indian Institute of Technology, Roorkee, have developed a high density memory device that promises to provide high speed data reading and writing even while requiring extraordinarily low power to operate it.

The new type of memory could potentially be used in future memory chips for digital devices like smartphones and tablets, as well as for large data storage. It may also find applications in memory-intensive computing tasks like video and multi¬media signal processing, pattern recognition, virtual reality, and machine learning.

In order to move towards further miniaturization of digital devices, scientists have been looking for new materials and processes including quantum mechanical phenomenon. Novel materials and material combinations are needed to fabricate what are called tunnel junctions with improved functionalities. One such potential contender is the Multiferroic Tunnel Junction (MFTJ)—a device made up of two ferromagnetic metal layers set apart by an ultrathin ferroelectric barrier. The aim is to obtain multiple logic states or precisely what is called ‘four logic levels’.

Researchers in the past have been able to achieve the four logic states, but these logic states have to be distinguishable and separable.  The team at IIT, Roorkee, has achieved this. It has developed Ferromagnetic Shape Memory Alloy (FSMA)-based MFTJ nonvolatile memory device. “Our memory device has shown tremendous improvement of near 140 per cent in the memory function,” Prof. Davinder Kaur, who has developed the device along with her research student Kirandeep Singh, told India Science Wire.

One of the key features of the device is that it shows a ‘four logic state’ resistance at room temperature that can be tuned both by electric as well as magnetic field. Further, it utilizes voltage instead of large electric current to switch the magnetic bits and write data into memory. Hence it is more energy efficient and dense and can bring down the cost per bit. The researchers have published their findings in journal Applied Physics Letters. (India Science Wire)

Bangalore Metro Rail Project: India signs €300 million Contract with European Investment Bank

Newsroom24x7 Staff 

Government of India and European Investment Bank (EIB) today signed the Finance Contract for lending of € 300 million for Bangalore Metro Rail Project Phase II Line R6. The agreement was signed by S. Selvakumar, Joint Secretary (BC), Department of Economic Affairs (DEA), Ministry of Finance on behalf of the Government of India and Andrew McDowell, Vice President, EIB, on behalf of the EIB.

Bangalore Metro Rail Project Phase II is to be jointly financed by the European Investment Bank (€500 million) and Asian Infrastructure Investment Bank (€300 million). The first tranche of Euro 300mn was signed today. The project envisages extension of East-West & North-South lines for Bangalore Metro Rail which includes a total length of 72.095 km (13.79 km underground) and 61 stations with 12 underground stations. The project implementation period is 5 years from date of commencement of the Project.

The objective of the project is to bring in a quantum improvement in the transportation sector in the city in tandem with the Bangalore Metropolitan Transport Corporation (BMTC) and other modes of urban transport. The project aims to ensure modern transport facility for the commuters. The spinoffs of the project would include employment opportunities, benefits to the economy, reduction of number of vehicles on road, less fuel consumption, reduction in air pollution, reduction in passenger travel time and also improvement in the aesthetic value of the city.

Embryo Transfer Technology: A promising revolution in Bovine breeding

Newsroom24x7 Staff

New Delhi: Embryo transfer technology (ETT) has revolutionized the breeding strategies in Bovines as a tool to optimize the genetic improvement in cattle.

Department of Animal husbandry, Dairying and Fisheries in co-operation with 12 States has undertaken a Mass Embryo Transfer programme in Indigenous Breeds under the scheme, National Mission on Bovine Productivity. It has been planned to carry out 440 embryo transfers during October 2-10, 2017 throughout the country. The programme is implemented with the objective of conservation and development of indigenous breeds under Rashtriya Gokul Mission.

Through the use of ETT, (i) a farmer can get a 5-6 fold increase in number of offsprings , (ii) the calves so born will be of high genetic merit and (iii) the offsprings born will be free from diseases.

The programme has been initiated in 12 ETT centres across the country from 2nd October and will continue till 10th October 2017. Under this programme, embryos of higher genetic merit indigenous bovines are being transferred in to surrogate cows. Embryos of Indigenous breeds such as Sahiwal, Gir, Red Sindhi, Ongole, Deoni and Vechur have been proposed to be transferred under this programme. On first day of ET programme held on 2 October, 35 Nos. of embryos were transferred in to recipients. Remaining will be transferred on different days till 10 October 2017.

The technology now being taken up to the doorstep of the farmers will result in rapid propogation of high genetic merit indigenous cattle.
