In microbial electrosynthesis (MES), the integration of novel materials is crucial for optimizing efficiency and enhancing performance. These materials are predominantly utilized in the development of electrodes, which form the critical interface between electrical circuits and microbial communities. Advanced materials such as carbon-based composites, nanostructured surfaces, and conductive polymers have been instrumental in improving electron transfer rates and expanding the surface area for microbial colonization. Furthermore, novel materials are being developed for membranes and separators to enhance ion selectivity and minimize energy losses within the system. These innovations collectively contribute to more efficient MES operations by optimizing the interactions between microbes and electrodes, thereby facilitating the effective conversion of carbon dioxide into valuable chemical products. Consequently, the adoption of novel materials is pivotal in advancing MES technology, providing new avenues for sustainable energy production and effective carbon utilization. This focus on material innovation not only enhances the technical capabilities of MES but also positions it as a key technology in the transition toward a more sustainable and circular carbon economy. Here we discuss recent discoveries in this area by our lab on the use of bio-generated materials in microbial electrosynthesis.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
