As the concentrations of CO2 in the atmosphere continue to rise, methods for alleviation are desperately needed. Instead of a greenhouse gas, CO2 can also be a valuable resource, but this requires technology to split it up. Among the proposed technologies to split CO2 is its capture and electrolysis in molten salts, turning CO2 into solid carbon and gaseous oxygen. This project aims to further this technology by looking closely at the processes taking place and creating new ways of valorizing the products to create a financial incentive for scaling. Smart utilization of this powerful technology will allow us to not only directly reduce the amount of CO2 in the atmosphere, but also to limit future emissions by empowering CO2-free energy conversion devices such as fuel cells, batteries, and supercapacitors. To keep the CO2 equivalents low and to not offset the positive effect of CO2 capture and utilization, the effect of green chemistry principles and their utilization will also be studied.

The efficient utilisation of bio-based resources is essential for achieving a sustainable, carbon-neutral society. AGRI-WASTE2H2 will focus on straw-derived cellulose – an abundant but underexploited agricultural side-product – as feedstock in an advanced electrochemical process, tailored for enhanced efficiency in the production of green hydrogen with significantly reduced energy consumption compared to standard water electrolysis. At the same time, the process will concurrently produce valuable platform chemicals and materials. AGRI-WASTE2H2 relies on the combined expertise of researchers in three Nordic-Baltic countries – Finland, Sweden and Estonia. The Synthetic Flow Chemistry group at Tallinn University of Technology, Estonia, will focus on transferring the electrochemical oxidation of cellulose into the flow regime, aiming to achieve high efficiency and productivity of the developed transformation. The scaling-up process in flow is a key step for a successful industrial application. AGRI-WASTE2H2 capitalises on the abundance of renewable electricity and agricultural side-streams in the Nordic-Baltic area to produce fuel and chemicals, thereby alleviating the region’s dependence on import of fossil feedstocks. As such, the project will result in tools for reduced CO2 emissions and increased regional resilience, while spurring the growth of new green industries of particular benefit for rural areas. The collaboration between researchers three Nordic-Baltic countries will enable results beyond what the individual partner can achieve alone and promote regional mobility and new collaborations. By leveraging our specialised know-how, we aim to drive innovation tailored to our regional needs and strengths.

Reproduction is regulated by the endocrine system and its disturbances by endocrine disruptive chemicals (EDCs) may lead to infertility. As humans are constantly exposed to EDCs through the use of common household items and personal care products, it is important to test chemicals for their potential activity as endocrine disruptors affecting reproductive function. Project MERLON aims to study the effects of EDCs on sexual development and function in order to deliver new approach methodologies (NAMs) for EDC identification. While MERLON targets the vulnerable stages of development from fetal to puberty, MERLON2, with additional partner TalTech, will add one more sensitive window of susceptibility in female reproduction to the project: the adult preovulatory ovarian follicle, where the oocyte maturation takes place. In collaboration with TalTech, it was recently demonstrated that follicular somatic cells (FSCs) lose sensitivity to follicle stimulating hormone (FSH) in the presence of a mixture of 13 EDCs. FSH is crucial for both, the oocyte maturation and for the synthesis of steroid hormones by the FSCs. We have also demonstrated the intricate heterogeneity of somatic cells in the ovarian follicle. The roles that FSC subpopulations play in the adverse effects of EDCs is unknown and unaddressed by the initial MERLON project. MERLON2 will complement the aims of the consortium by developing NAMs based on single cell transcriptomics, automated image analysis and machine learning to understand the effect of EDCs on FSC subpopulations and their sensitivity to FSH. This will increase the research output for MERLON in the number of proposed NAMs and quantitative adverse outcome pathways. As a result of MERLON2 the range of stakeholders will enlarge, increasing the public awareness related to the harmful health effects of EDCs, and proposing new approaches to resolve the complicates issue of testing substances in everyday products for their adverse effects on human fertility.

The CROSS project aims to strengthen the European Research Area by developing innovative tools to mainstream the new Charters´ principles, fostering organisational change and career interoperability. Key outputs include a Self-Assessment Competence Tool, a comprehensive Roadmap for transversal skills training, a Mentoring Handbook, a Roadmap for career counseling, an Intersectoral Collaboration Handbook, and an HRS4R Repository. These form a comprehensive set of career management services, which will be piloted and implemented across four intersectoral networks. The development of these resources will follow a co-creative process, engaging stakeholders across Europe, facilitated through the creation of our ResearchComp Community of Practice. This approach ensures their adaptability to diverse European ecosystems. A key component of CROSS is the creation of a platform designed to support institutions in obtaining the HRS4R award. This platform can also serve as a shared resource for all projects funded under this call, ensuring their continued use and expansion beyond the project’s lifecycle. By promoting organisational change, CROSS will benefit research-performing organisations and researchers at all career stages, significantly improving career prospects and delivering broader societal impact.

Through a comprehensive educational initiative, XiA aims to address the skills gap in advanced digital health interoperability standards among healthcare providers, digital health solution providers, and individuals. By developing high-quality educational materials and courses, XiA seeks to equip stakeholders with the necessary skills to embrace EHDS-related standards and foster a culture of interoperability.

Sustainable aviation fuels (SAF) are the only short-term alternative to fossil fuels in aviation. Considering the increased number of passengers forecasted in the near future, a massive increased in SAF production has been estimated in the years to come. To fulfill this increase in demand, the combination of existing and new renewable production chains is needed. Current SAF-producing pathways are at different levels of maturity, implementation or even commercialization. However, lowering the cost and supply chain development are key challenges for commercial-scale SAF deployment. Using biowastes as feedstock for SAF is challenging but necessary to make SAF competitive with fossil fuels. In this context, yeasts may be key players to generate economically-viable SAF intermediates (terpenes or fatty acids (FA)) in an environmentally-friendly way from biowaste. This SAF production by biological means is very new and presents a lot of remaining challenges and training gaps that have to be addressed. YAF research programme aims at; i) producing carbon sources from biowastes, ii) developing new yeast cell factories to produce SAF, iii) designing new bifunctional catalysts, iv) achieving efficient strategies for FA/terpenes extraction, and v) creating robust framework tailored to the scaling-up methodologies and life-cycle sustainability assessment of different SAF producing routes, which will support decisionmaking. To achieve this, the right integration of biology, biotechnology, chemical engineering and environmental sciences will be required. Thus, the prime training/networking aim of YAF is to train the next generation of researchers in a highly interdisciplinary and intersectorial research environment such that they can soundly address upcoming challenges concerning production yeastbased SAF. YAF has been designed to strengthen European research and innovation, enhancing research visibility and generating a critical mass to address European (and global) challenges

Asymmetric catalysis plays one of the most important roles in the modern organic chemistry providing methods for the synthesis biologically active compounds and pharmaceuticals. Merging well-developed organocatalysis with electrochemistry opens new horizons for asymmetric transformation beyond the classical thermochemical activation. This approach is sustainable, since it employs harmless organocatalysts to induce chirality and electrons as traceless and green reagents to generate highly reactive radical species under mild reaction conditions avoiding the utilization of highly toxic and expensive RedOx chemicals. The efficiency and reliability of such transformations can be enhanced by performing the reaction in continuous-flow mode. The project is an example of cutting-edge science combining different research areas of organic synthesis and chemical engineering that can be potentially applied for discovery of new and potent life-saving drugs.

We shall custom-engineer MAS and metabolomics NMR and apply it on selected problems, notably Alzheimer's, Parkinson's, COVID, diabetes and cardiovascular conditions, fluor ion batteries, wood chemistry, also universal AI-assisted diagnostics and monitoring. We shall in particular focus on phytochemicals as the fastest and least harmful option to address acute health issues like SARS infection and neurodegenerative diseases. New hardware, based on fast mechanical spinning up to 15 Million RPM, electron spin polarization transfer (DNP), a sophisticated multi-axes sample rotation (DOR) and also 1.2GHz NMR magnets are expected to provide an unprecedented resolution and sensitivity in NMR, rendering it principally more helpful for a significantly wider range of material sciences and biomedical topics. In complex functional cases, the NMR will be arguably more informative and convenient than presently popular methods of plasmon resonance, CryoEM, X-ray or MS.

In heart muscle cells, calcium regulates cells' contraction and mitochondria energy production needed to perform mechanical work and maintain ion balance. The primary calcium source in adult mammalian cells is the sarcoplasmic reticulum (SR). Recently, it has been shown that SR and mitochondria are physically linked and regulate mitochondrial respiration. The precise interaction between them is essential for maintaining energy balance in the heart, yet many aspects of this regulatory pathway are still poorly understood. This project aims to unravel mechanistic aspects of SR-mitochondria interaction by taking advantage of structural and functional changes in heart muscle cells during development and in disease. We expect this knowledge to be applicable at the other end of the heart physiology spectrum – disease, as failing hearts resemble in many ways the hearts from early stages of development.

Around 13% of the adult population suffers some form of kidney damage, and the death rate of complications related to chronic kidney disease (CKD) is very high. The primary cause of death in CKD patients is cardiovascular disease. Vascular calcification (VC), one of the cardiovascular complications, is prevailing in CKD. One of the causes of VC in CKD is the disbalance between VC inhibitors and inducers due to failed kidney function. During the dialysis therapy for end-stage renal disease (ESRD) patients, inducers and also inhibitors are removed from the patients’ blood. This project (VasCalDi) aims to develop unique optical methods to estimate VC and monitor VC inhibitors removal during dialysis in patients with ESRD. The project's goal is to make the work of hospitals and physicians more efficient and improve the life quality and survival of ESRD patients by monitoring disturbances in VC inhibitor balance and vasculature allowing timely interventions.

MARTA addresses agronomically and economically important traits in plant breeding to support sustainable and self-sufficient food production in Estonia. We will create novel breeding knowledge together with a toolbox of modern breeding tools (including novel genetic markers, genomic selection and genome editing). Target traits for breeding include climate-resilience, disease resistance, product quality, production sustainability and high yield. We have chosen 7 strategically important crop species for Estonia as prime targets for application of modern breeding tools. Wheat, barley and potato are important in ensuring energy and protein supply as food crops. Nitrogen fixing capability and high protein content (29% of seed dry matter) of faba bean make it a strategically important crop in Estonia’s protein self-sufficiency. Apple and blackcurrant are important horticultural crops ensuring a healthy diet and providing a local supply of vitamin- and antioxidant-rich resources for the industry. Bridging the gap between fundamental and applied plant biology will allow faster translation of research results into breeding. The research questions (Q) addressed in the project range from broad phenotypic and genotypic screening to application of precision breeding and creation of novel genetic markers. The establishment of a pipeline for using genomics and transcriptomics results will speed up and create new possibilities for breeding climate-resilient future crops. Q1 aims to create specific scientific knowledge, data and results for input to Q2 and Q3, which serve to develop modern tools for breeding (e.g. novel genetic markers for disease resistance, pre-breeding material from precision breeding). MARTA will generate and validate a modern breeding toolbox for flexible and sustainable plant breeding in Estonia to ensure food security.

Neuronal plasticity, the ability of the nervous system to adapt to internal or external stimuli, is a fundamental property that underlies brain development, learning, memory, and resilience to neurodegenerative disorders. At the molecular level, neuronal plasticity depends on the activation of neuronal activity-regulated genes (nARGs), a process tightly controlled by enhancer regions—short regulatory DNA sequences. Recent findings reveal that active enhancers produce enhancer-derived RNAs (eRNAs), which may play crucial roles in gene regulation through complex interactions with DNA, RNA, and proteins. Despite their potential significance, the function of eRNAs in neuronal activity remains poorly understood due to their transient nature and technical challenges in studying them. This project aims to develop innovative experimental approaches to unravel the role of eRNAs in nARG activation. Using rodent primary neuronal culture —a well-established model for studying neuronal plasticity—the project will systematically analyze eRNA responses to external stimuli with high temporal resolution. Comprehensive sequencing technologies will be combined to characterize the molecular features of eRNAs. These data will be complemented by epigenomic profiling to correlate enhancer activity with transcriptional dynamics. The project will also investigate potential links between eRNA features and neurodegenerative disease-associated mutations, providing insights into how brief stimuli-related gene activation may contribute to disease phenotypes. Together, these studies will create a framework for understanding the regulatory roles of eRNAs in neuronal plasticity and their broader implications for brain development and disorders.
