Patent EP0267392A1 - The chemical synthesis of …

Abstract:
Self-protective/self-healing coatings are imperative for sustained corrosion protection and to minimise economic losses. The present research focuses on this premise. We report here the synthesis of a series of new effective organic corrosion inhibitors for corrosion protection of the aluminium alloy - AA2024-T3. The synthesized inhibitors were encapsulated in silica nano-containers and doped in GPTMS – Titanium isopropoxide based sol-gel coatings for “on-demand” release of the inhibitor. Anticorrosion behaviour of uncoated and coated coupons was characterized by Electrochemical impedance spectroscopy (EIS). The immersion time for evaluating the sustainability of the coatings in 3.5% NaCl was 168h as per MIL’s specifications. The localized corrosion and dissolution of the intermetallic particles (S & Ө phases) on the aluminium alloy was examined by using field emission scanning electron microscopy attached with energy dispersive X- ray spectroscopy, X-ray photoelectron spectroscopy and 3D profilometry. The acquired results revealed that, the synthesized inhibitors offered sustained corrosion protection to AA2024-T3. The coupons qualified salt spray test as per ASTM standard B117. The mechanism of action appeared to be formation organic thin layer of insoluble complex on the surface, thereby preventing the dislodgement of the inter-metallics and pitting corrosion characteristic of the AA2024-T3 alloy.

Abstract:
Electrochemical sensors for glucose can be divided into enzymatic and non-enzymatic. Enzymatic sensors are more specific in glucose determination. On the other hand non-enzymatic sensors are more chemically and thermally stable. Devices based on the synergistic effect of carbon nanostructures, conductive polymers and noble metal nanoparticles can be successfully used as enzymatic (using GOx) and non-enzymatic (without GOx) sensors for glucose detection. In this work, composite material containing GQDs, PPyNPs and AuNPs was synthesized and applied in both types of electrochemical sensors. Constructed systems were electrochemically characterized by voltammetric methods and their sensitivity towards glucose was examined.

Photochemical Synthesis of Gold Nanorods - Journal …

Biography:
Cecile Reynaud has her expertise in the synthesis and chemical physics of nanomaterials. Her work has mainly dealt with silicon nanocrystals and aligned carbon nanotubes. She was for 15 years at the head of the Laboratory of Nanometric Assemblies (LEDNA) in the fundamental research division of Saclay CEA center. The LEDNA group follows the "bottom-up" approach of nanosciences. It develops its own synthesis methods and obtains nanostructured materials with well-controlled characteristics. The applications are relevant for energy, health, environmental issues and the development of composite materials. The group also develop the up-scaling of its processes to allow their industrial transfer.

Abstract:
In this study, both chemical precipitation and mechanical milling techniques were used to synthesize either Fe nano-particles or mixed Fe, Al, Ti nano-composites using iron rich industry waste such as red mud as precursor. Further heat treatment of chemically and mechanically treated red mud lead to in-situ formation of nano-sized particles or composites. Such metal matrix composites have attracted much attention due to its use as structural materials in automotive and transportation industries because of their low density, high specific modulus, strength, wear and corrosion resistance. The present work used iron and titanium rich fraction of chemically treated iron rich industrial rejects for preparation of value added Fe and Fe-Al-Ti nano-material. The structural transformation behavior from bulk to nano at different temperatures has been assessed by XRD and SEM. SEM results clearly show that chemical precipitation produced Fe nano-crystals that were obtained after using Fe enriched chemically treated red mud residue whereas mixed nano-material were obtained after mechanical milling.
