NATIONAL: SCIENCE & TECHNOLOGY: JNCASR Scientists Develop Brain-like Computing with Industry Compatible Nitride Semiconductors

They used scandium nitride (ScN) to develop a device mimicking a synapse that controls the signal transmission as well as remembers the signal.

A team of scientists from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have used scandium nitride (ScN) and Complementary Metal-Oxide-Semiconductor (CMOS) compatibility to develop brain-like computing.

This invention can provide a new material for stable, CMOS-compatible optoelectronic synaptic functionalities at a relatively lower energy cost and also potential to be translated into an industrial product.

According to the Department of Science and Technology, the JNCASR team led by Dheemahi Rao who were working on nitride-based materials used their background for developing hardware for neuromorphic computing. They used ScN to develop a device mimicking a synapse that controls the signal transmission as well as remembers the signal.

“The JNCASR team demonstrates an artificial optoelectronic synapse with ScN thin films that can mimic synaptic functionalities like short-term memory, long-term memory, the transition from short-term to long-term memory, learning–forgetting, frequency selective optical filtering, frequency-dependent potentiation and depression, Hebbian learning, and logic-gate operations,” states the department.

Compared to the existing materials used to demonstrate optoelectronic synapse, ScN is more stable, CMOS compatible, and can be seamlessly integrated with existing Si technology. It can act as a platform for both excitatory and inhibitory functions. The industrial processing techniques of ScN are similar to the existing semiconductor fabrication infrastructure. Response to the optical stimuli also has the advantage of possible integration with photonic circuits known for higher speed and broader bandwidth than electronic circuits.

“Our work enables neuromorphic computing research with a stable, scalable, and CMOS-compatible III-nitride semiconductor that exhibits both excitatory and inhibitory synaptic functionalities. Unlike the previous works on all-electronic synapse, our work shows an optoelectronic synapse with a large bandwidth, reduced RC delays, and low power consumption,”said Dr. Bivas Saha, Assistant Professor, JNCASR.

Apart from JNCASR, researchers from the University of Sydney (Dr. Magnus Garbrecht and Dr. Asha I. K. Pillai) also participated in this study published recently in the scientific journal Advanced Electronic Materials.

Citizens of Philippines, Morocco, Sri Lanka, Uganda, Ethiopia, Republic of Guinea, Sierra Leone, Burkina Faso and Togolese Republic will enrol on the platform.

Around 70 million citizens in Philippines (80% of the population) have enrolled themselves on their national digital identity programme rolled out by Modular Open-Source Identity Platform (MOSIP), a digital identity platform developed by a team at the International Institute of Information Technology Bangalore (IIITB).

Upon the request of World Bank to initiate research and development, the project provides digital identities similar to Aadhaar to underdeveloped and developing countries. So far, 16 lakh lines of codes have been developed and used by countries, free of cost.

People of 9 nations to enroll

Although the project was first aimed at providing MOSIP to five countries, it has now been extended to nine countries. Philippines, Morocco, Sri Lanka, Uganda, Ethiopia, Republic of Guinea, Sierra Leone, Burkina Faso, and Togolese Republic are the countries whose citizens will enroll on the platform. A team of 30 people, comprising top designers and others from software, database design, security and privacy departments, are working on the project at IIITB.

“Along with technical know-how, we will also help the countries with technological training. Data, privacy, and security will all be within their own country and their policy, we will not interfere with it. We are providing digital identity for the world in a modular nature so that it can be customised to their needs. For instance, in Philippines, English, and Filipino are the languages which used, while in Morocco, it is French and Arabic. Different countries have separate biometric needs and accordingly, the modular biometrics will be used,” explained Debabrata Das, Director, IIITB, who is also the Chairman of Executive Committee for the project.

Scalable. secure

Prof. Rajagopalan, President of MOSIP project, added that the project is highly scalable and secure. The developers have also figured out a way to operate in 5,000+ habitable islands of Philippines where there is no good internet connection.

“We have developed a new technology to identify people where there is no internet or low bandwidth connection. A lot of research went into it and we developed a secure QR code which can be stored in local servers and mobiles and can be used to authenticate each other. Later, when they get internet connection, the information can be exchanged and authenticated,” he further said.

The project is also being funded by Bill and Melinda Gates Foundation, Norad, Sir Ratan Tata Trust, Pratiksha Trust and Omidyar Network.

NATIONAL: SCIENCE & TECHNOLOGY / RESEARCH: Indian Institute for Science (IISc.) Researchers have ‘Nano Solution for Wastewater Treatment’

They have developed a metal organic framework (MoF) nanocomposite by intercalating the properties of graphene oxide and UiO-66-NDC.

Researchers in the Indian Institute of Science’s (IISc.) have developed a novel nanocomposite material for improved wastewater treatment.

A team of the Interdisciplinary Centre for Water Research (ICWaR) in the IISc., led by Praveen C. Ramamurthy, has developed a metal organic framework (MoF) nanocomposite by intercalating the properties of graphene oxide and UiO-66-NDC.

Heavy metals

According to IISc., industrial effluents containing heavy metals have polluted our water sources for decades. Lead, a heavy metal commonly found in discharge from paint and battery manufacturing plants, is a major water pollutant whose presence severely affects human and animal health.

In recent years, scientists have turned to nanotechnology to develop absorbent materials that can remove heavy metals for improved wastewater treatment.

However, existing adsorption materials and technologies are expensive, and their applications are limited by where they can be implemented and how efficiently they can adsorb lead. This demands the development of novel, low-cost and structurally stable composite materials for wastewater treatment. To this end, ICWaR researchers have developed a novel nanocomposite material.

The researchers have demonstrated that the new nanocomposite can adsorb lead (Pb) from simulated wastewater systems.

Four-fold capacity to absorb lead ions from wastewater

The team demonstrated that the newly developed MOF nanocomposite adsorbent has approximately four-fold enhanced capability in removing lead ions from wastewater compared to previously reported studies of graphene oxide. The material exhibits a stable crystalline structure. Modelling and simulation results also support enhanced efficiency in lead adsorption due to the adsorbent molecular architecture.

The new nanocomposite has improved adsorption and high regeneration and reusability capacities, making it an effective tool in the wastewater treatment of lead ions.
