Накратко на български

Наночастици, вградени в органични соли (течни или твърди), се анализират чрез високоразрешаващо изображение, за да се разбере връзката между структурата и електроактивността им. Тези материали помагат за подобряване на биоимплантите и системите за съхранение на енергия.

Surface characterization of nano-particle embedded organic ionic plastic crystals and ionic liquid using advance 3D high resolution optical and electrochemical imaging

The nanoOIPC MSCA action objective was to investigate the electroactivity of nanoparticles (NPs) embedded in ionic liquids (ILs) or organic ionic plastic crystals (OIPCs) as nanocomposite materials and exploit them as soft electrode materials. There is an urgent need for these materials, e.g. for bioimplantation and energy storage. Several critical technical innovations are required to facilitate this advancement, particularly insight into the electroactivity-structure relationship. ILs and OIPCs are both large organic salts. ILs have melting points below r.t., while OIPCs are solid at r.t. with melting points between 60-120°C. OIPCs are characterized by a plastic phase near r.t. that, when combined with embedded NPs, makes them excellent electroactive material candidates. Our approach was to combine different multiscale, high-resolution electrochemical and optical imaging, to assess the electroactivity-structure relationship of nanocomposites operando, simultaneously. Through this research program, we pioneered electrochemical single metal NP impact detection at immiscible, micro liquid|liquid interfaces – both water|oil (w|o) and water|ionic liquid (w|IL). We made several successful breakthroughs. First, we developed several low-cost ILs and OIPCs at high purity through solvent free and high yielding processes. Next, we discovered that residual metal reducing agent, LiBH4, used to form the NPs persists in the IL medium and grows to form inorganic nanocrystals (NCs). The growth of inorganic salts within these next generation electrolytes is a critical parameter that needs to be addressed and is rarely mentioned in the scientific literature. Our research program has strongly highlighted this fact but also shows the means with which it can be exploited to societies advantage. Finally, this research program has been an immense success for both the Experienced Researcher (ER) and the host-organization (Université Paris Diderot, UPD). The exchange of knowledge (described below) has enhanced the perspectives of both the ER and UPD.

Цел на проекта

Soft, flexible electrode materials are needed for a variety of health and energy applications, e.g. nano-electrodes for bio-implantation and light weight electrodes for solar energy capture. Organic ionic plastic crystals (OIPCs), similar to ionic liquids (ILs), embedded with nano-particles (NPs) as reactive sites offer highly tunable solutions. OIPCs are also advantageous owing to a plastic phase that allows the conductive nano-plastic material to be molded at high temperature. However, the OIPC/NP field is in its infancy and little is understood regarding NPs stability/reactivity.By combining high resolution 3D optical imaging with electrochemistry, this project aims at mapping the NP reactivity and simultaneously correlate it to surface and chemical data based on NP density, from single NPs to collective or percolated films. New insights will be gained in the inherent chemical properties of composite materials as well as NP size, localization, etc. The synergistic interactions between NPs and ILs/OIPCs will be explored and exploited and will open new fields of research in materials science and optical imaging. Breakthroughs will include i) development of advanced plastic nanoelectrodes; ii) multiscale imaging (nm-µm) of innovative nanostructured electrodes.The experienced researcher (ER) will be trained in high resolution imaging techniques, while he is highly qualified to introduce the topics of IL/OIPC to the host laboratory. This new experience in optics, within the provided multidisciplinary scientific environment, will be an opportunity for him to complement to his current experience of chemistry. Dr. F. Kanoufi (supervisor) will also mentor the ER in course preparation and strategies through a teaching tribune. The ER will also conduct outreach events to the public with impressive video and hands-on demonstrations such as “mold your battery with Playdoh-like nanocomposites”. Through this critical “transfer of knowledge” the ER’s career will be enhanced.
