Wearable motion sensors are made of materials that convert the mechanical strain that arises from human movement into electrical signals. The material must be flexible, robust, and highly sensitive to both large and subtle movements.
The INST team has been working in this area of photocatalytic water splitting to generate hydrogen for quite some time now. “The energy crisis and ever-threatening climate crisis urged us to work on this promising way of hydrogen production through photocatalytic water splitting. The stability and chemical flexibility of having different organic groups in carbon nitrides triggered us to work on these cost-effective organic semiconductor materials for sustainable hydrogen production,” added Dr. Kamalakannan.
The Indian Space Research Organisation (Isro) is preparing for multiple flights of the specially designed test vehicle that will be used to test the Crew Escape System (CES), which will be a crucial element of India’s first human space flight mission (Gaganyaan).
A team of scientists led by Dr. Neelotpal Sen Sarma from the Institute of Advanced Study in Science and Technology, Guwahati, an autonomous institute of the Department of Science & Technology, Government of India, has filled the gap.
ISRO has been continuously monitoring the spacecraft and its five scientific instruments, and officials said scientific analysis of the data being received from MOM spacecraft is in progress.
Indian scientists, for the first time, have developed a thermally stable and cost-effective electronic polymer-based sensor for rapidly detecting nitro-aromatic chemicals used in high-energy explosives. The detection of explosives without destroying them is essential for protection, and criminal investigations, minefield remediation, military applications, ammunition remediation sites, security applications, and chemical sensors play a vital role in such cases.
Recognizing the importance of nurturing innovation and creativity in a knowledge economy, India is taking great strides in strengthening its intellectual property ecosystem in recent years. In order to create a conducive environment for innovation, Department for Promotion of Industry and Internal Trade has been working towards promoting greater collaboration between industry and academia. This can be achieved by facilitating commercialization of research undertaken in educational institutions.
The MOF composite has great capability for selective separation of the oils from oil/water mixtures, and the separation efficiency lies between 95% and 98%, irrespective of the chemical composition and density of the oils. Besides, the MOF composite is also able to absorb large volumes of oils and can be reused for a minimum of 10 times so that the sorbents can provide more recovery of the spilled oil.
The flying vehicle will be capable of vertical take-off and landing using its coaxial quad-rotor. It weighs a total of 1,100 kilograms and can handle a takeoff weight of 1,300 kilograms. The rotors would be powered using an electric battery. On the streets, the car would be powered using biofuel.
Space weather refers to the conditions in the solar wind and near-Earth space, which can adversely affect the performance of space-borne and ground-based technological systems. The space weather near the Earth is mainly due to Coronal Mass Ejections (CMEs), which are frequent explosive expulsions of huge magnetized plasma from the Sun into its surroundings, which can blow past the Earth. Example of space weather events is the geomagnetic storm, a perturbation in the Earth’s magnetic field, which can last for few hours to few days. Understanding of how events in the solar atmosphere influence space weather is necessary for monitoring and maintaining our satellites.
