At a tech exhibition, young researchers present innovations to critical concerns

Over the two days of the Research and Technology Showcase 2022 exhibition, which was jointly organised by NED University of Engineering and Technology and Sindh Higher Education Commission at Expo Centre and concluded on Friday, large crowds came to see ideas for innovative solutions to everyday pressing issues.

The expo featured 340 locally developed innovations from 32 colleges from across the region. A considerable number of these projects were undertaken with the goal of finding answers to Pakistan’s numerous pressing problems.

“Considering the fact that our country lacks low-cost efficient technologies for water purification and wastewater recycling, our team has developed ion exchange membranes, currently being imported at a high cost. These special membranes transport certain dissolved ions while blocking other ions or neutral molecules,” explained Dr Shazia Perveen of the NED university’s chemistry department.

She stated that trials had been finished and that finance support was required to begin commercial manufacture of the membrane.

Students from NED University’s civil engineering department had samples of limestone calcined clay cement on exhibit at another stall, which might reduce carbon dioxide emissions by more than 30% compared to ordinary cement.

“This blended cement produced for the first time in Pakistan by using local raw material has demonstrated greater durability,” Mohammad Hasan Khan and Miqdam Sheikh told.

Mariam Sajid, representing her Dawood University of Engineering and Technology group, demonstrated a mobile phone application that might help monitor the quantity and quality of water in underground and overhead household tanks.

Her institution has created an air quality monitoring gadget as well as a smart system for detecting harmful substances.

“Leakage of hazardous gases in houses and commercial centres has become a serious matter that has claimed many lives in recent past. Our system would help detect harmful leakages for timely action,” shared project proponents Saqib Ali Zaidi and Farjad Raza.
