Based on requests received from local administration due to flood like situation following heavy rainfall in Andhra Pradesh, Indian Naval aircraft, Flood Relief Teams (FRTs) and Diving Teams from Eastern Naval Command at Visakhapatnam have been deployed to strengthen Humanitarian Assistance and Disaster Relief (HADR) efforts in the State. The Indian Navy has so far rescued 22 people stranded in flood-affected areas of Andhra Pradesh. More than 1000 kg of food items have been air-dropped for the stranded persons. 10 flood relief teams have also been deployed to enhance rescue…

A new nanostructure developed by Indian scientists can detect nitrogen oxides at very low concentrations at room temperature, which could meet the urgent need for accurate air quality monitoring systems in urban and industrial areas. Gas sensors play a vital role in modern technology, where they provide environmental monitoring, industrial safety and healthcare diagnostic facilities. The field of gas sensors is constantly growing through innovations in materials and technology, aimed at enhancing critical parameters such as sensitivity, selectivity, response and recovery time, stability and operating temperature. The primary objective of…

INST researchers have developed a low-cost method for removal of toxic chromium from wastewater from industries such as leather tanning and electroplating by using “sunlight” as a catalyst in combination with microfluidic technology. Toxicity of hexavalent chromium is a serious concern and as per World Health Organization reports, the tolerable concentration of hexavalent and trivalent chromium in drinking water is limited to 0.05 mg/l and 5 mg/l respectively. Thus, it becomes imperative to convert this hexavalent form of chromium to trivalent form. Several chemical and physico-chemical measures, such as ion…
