To expedite the development of the proton-based technology, an international research team has created a new hybrid material that successfully delivers protons at high humidity and temperatures two crucial challenges faced in previous attempts.
Karachi: Former students of the University of Karachi (KU)-based in the Washington DC and Baltimore area of the USA have donated a system to energise two of the key faculties of the university by solar power.
Sindh Law and Environment Minister Barrister Murtaza Wahab inaugurated the 32.5 kilowatts grid-tied solar system installed on the KU campus to energise its Arts and Social Sciences faculties. The Washington DC and Baltimore chapter of Karachi University Alumni Association donated the renewable energy system comprising of 74 solar panels having cost around Rs 3.05 million. The system will help KU save 150 units of electricity daily.
Earlier, the same alumni association donated the solar system for the Department of Applied Chemistry and Chemical Technology of the KU.
New Bluetooth-Low-Energy-Based Wireless Neuronal Recording System
Scientists have now created a compact, lightweight, Bluetooth-low-energy-based wireless neuronal recording system.
The wireless system was developed by researchers from the Department of Electrical and Electronic Information Engineering, Department of Computer Science and Engineering, Department of Applied Chemistry and Life Science, and the Electronics-Inspired Interdisciplinary Research Institute (EIIRIS) at the Toyohashi University of Technology.
The weight of the system is less than 3.9 g and it measures 15 × 15 × 12 mm
