Fe2+ doping in II-VI semiconductors, due to the absence of energetically accessible multiple spin state configurations, has not given rise to interesting spintronic applications. In this work, we demonstrate for the first time that the interaction of homogeneously doped Fe2+ ions with the host CdS nanocrystal with no clustering is different for the two spin states and produces two magnetically inequivalent excitonic states upon optical perturbation.

Climate resilience is the ability to anticipate, absorb, accommodate, and recover from the effects of a potentially hazardous event. The benefits of resilient power infrastructure are much greater than the costs, considering growing climate change events. It is estimated that for every dollar invested in climate resilient infrastructure, six dollars can be saved. According to the World Bank, if the actions needed for resilience are delayed by ten years, the cost will almost double.

India is one of the few countries where environment education is compulsory at all levels of formal education. The concepts introduced at school are centred on the need to conserve for future generations, halt resource depletion, reduce pollution, and protect wildlife, with very limited focus on the effects of greenhouse gases, impacts of chlorofluorocarbons, and other topics of immediate concern.

Forest fires are on a rampage in Uttarakhand. Snow on the Tibetean plateau aka the world’s roof, surrounded by Mount Everest and K2, two of the highest mountains in the world, is melting at a rapid rate. The national capital witnessed one of the coldest Novembers recently, with temperature dipping to 10 degree Celsius. Do we need more reasons to realise the world is on the edge of a precipice?
