Hydrometallurgical techniques for the selective recovery of Zn, Mn and Pb in that order from sludges or various metallurgical residues can include leaching steps to extract the zinc and manganese; the steps of removing iron, aluminum and silica from the leaching solutions; and recovering manganese and zinc by precipitation. Mn can be precipitated from an initial leaching solution as well as a secondary leaching solution obtained by leaching the slurry of the initial leaching step. Various other waste streams can also be treated.

A process has been developed in order to recover and recycle the metals present in spent batteries, including alkaline spent batteries alone or mixed with other types of spent batteries. This method shows a good potential in terms of metals recoveries efficiencies and economic feasibility. Firstly, the spent batteries are crushed (optionally after having been frozen in the case of spent batteries of mixed types). Then, the undesirable parts (plastics, steel cases, papers, etc.) are removed by screening. The collected powder, containing the metals, is mixed with a solution of sulfuric acid in the presence of a reducing agent. The solid/liquid separation is carried out by filtration and the leachate is purified in order to selectively recover the metals. The purification steps consist of: a) recovering Zn by solvent extraction followed by an electrowinning process; b) simultaneously recovering Mn and Cd by solvent extraction process; c) selectively recovering Cd from the mixture solution of Cd and Mn by electrowinning process; d) precipitating Mn from a pure solution of MnSO_(4 )in a carbonate form; e) removing the impurities present in the effluent by solvent extraction in order to obtain a pure NiSO_(4 )solution; f) precipitating Ni from a NiSO_(4 )solution in a carbonate form.

A synthetic neuronal structure makes use of a semiconductor-metal phase transition material having material regions separated by discontinuities. The discontinuities represent interfaces such that different phases in two adjacent regions result in a metal-semiconductor interface. The interface supports a charge accumulation and a discharge of accumulated charge when an activation energy provided, for example, by electrical current, localized heating or optical energy, reaches a threshold necessary for breakdown of a potential barrier presented by the interface, and thus mimics a leaky integrate-and-fire neuron. With many such interfaces distributed through the structure, the local inputs to a neuron become a weighted sum of energy from neighboring neurons. Thus, different combinations of signals at one or more inputs connected to the structure will favor different neural pathways through the structure, thereby resulting in a neural network.

M-ERA.NET 2 aims at coordinating the research efforts of the participating EU Member States, Associated States and Regions as well as of selected global partners in materials research and innovation, including materials for low carbon energy technologies and related production technologies. A large network of 43 national and regional funding organisations from 23 EU Members States and Associated States and 5 countries outside Europe will implement joint calls to fund excellent innovative transnational RTD cooperation, including one call for proposals with EU co-funding and additional non-cofunded calls. Continuing the activities started under the predecessor project M-ERA.NET (2/2012-1/2016), the M-ERA.NET 2 consortium will support relevant thematic areas, such as -for example- surfaces, coatings, composites, additive manufacturing or computational materials engineering. Research on materials enabling low carbon energy technologies will be particularly highlighted as a main target of the cofunded call (Call 2016) with a view to implementing relevant parts of the Materials Roadmap Enabling Low Carbon Energy Technologies (SEC(2011)1609), and relevant objectives of the SET-Plan (COM (2009)519). The appropriate scope of the cofunded call and the additional joint calls will be defined in cooperation with relevant stakeholders including national and regional RTD communities, the EC and the EMIRI (Energy Materials Industrial Research Initiative) as well as an external Strategic Experts Group. M-ERA.NET 2 will support the whole innovation chain, clarifying for each topic the appropriate Technology Readiness Levels (TRLs) to be addressed through the transnational RTD projects. The consortium will be aware of the TRLs which are covered by the EC through Horizon 2020 topics as well as by other schemes. Gaps will be identified and M-ERA.NET 2 will aim at offering a complementary support scheme.

The Transformations to Sustainability (T2S) ERA-NET Cofund programme will be implemented in the context of a Belmont Forum Collaborative Research Action in cooperation with the NORFACE (New Opportunities for Research Funding Agency Cooperation in Europe) network and the International Social Science Council (ISSC). A comprehensive and concerted research initiative is needed that can boost research on transformations to sustainability, that can catalyse new kinds of solutions to environmental and social challenges. This T2S programme therefore seeks to bring into being and nurture integrated teams of scientists from relevant academic disciplines including, as appropriate, social, natural, human, natural, engineering, agricultural and health/medical sciences disciplines and societal stakeholders to produce new knowledge and perspectives that can contribute to finding equitable and durable solutions to the challenges of sustainability in specific contexts, in support of the Sustainable Development Goals. This programme will contribute to re-structuring the broad field of sustainability research to place social science at the heart of interdisciplinary efforts and will contribute to a step change in scale and scope for research programming on this topic. This future-oriented call will be jointly undertaken by major funding agencies in Europa, the United States, Brazil, Taiwan and Japan. The T2S programme will coordinate the research efforts of the participating Member States and international partners by implementing a joint trans-national call with European Commission co-funding to fund innovative comparative, transnational and interdisciplinary research initiatives within this thematic field. The T2S partners will pursue the expansion of their present effective collaboration and actively strive at widening the consortium.
