AbstractGraphene-based spintronic devices require efficient spin injection, and dielectric tunnel barriers are typically used to facilitate spin injection. However, the direct growth of ultrathin dielectrics on two-dimensional surfaces is challenging and unreliable. Here we report spin injection in graphene lateral spin valves using ferromagnetic van der Waals contacts of indium and cobalt (In–Co), and without the deposition of dielectric tunnel barriers.

Developing nations face escalating loss and damage from extreme weather and from slow onset events such as melting glaciers, desertification and sea level rise. Loss and damage due to climate change could cost the global economy $19-$59 trillion a year by 2049, suggests recent research. Loss and damage funding is in addition to the climate finance needed by developing countries for mitigation.

चूंकि कॉप29 में वार्ता का दूसरा सप्ताह शुरू हो चूका है, इसकी सफलता इस बात पर निर्भर करेगी कि देश नए वित्त लक्ष्य पर सहमत हो पाते हैं या नहीं। जलवायु वित्त लक्ष्यों को प्राप्त करने में विलंब से भविष्य में लागत में और अधिक वृद्धि होगी। बाकू में प्रगति की कमी ने रियो में जी-20 बैठक की ओर ध्यान आकर्षित कर दिया है, क्योंकि जी-20 देश मिलकर 80 प्रतिशत ऊष्मा-अवरोधक उत्सर्जन में योगदान करते हैं। जलवायु परिवर्तन के प्रभावों को कम करने और उसके अनुकूल होने के लिए पर्याप्त धनराशि उपलब्ध कराने पर सहमति...
