Romain Gautier is a CNRS research scientist at the Institut des Matériaux de Nantes Jean Rouxel. His expertise lies in the synthesis and structural characterization of new functional inorganic and hybrid materials for optics. He received his Ph.D. in 2010 from the Ecole Nationale Supérieure de Chimie de Rennes and then joined Northwestern University for a postdoc. In recent years, he has employed Machine Learning approaches to assist and accelerate the discovery of new materials.

AJFC obtained his B.S. in Chemistry from the University of Seville (Spain) in 2009, followed by an M.S. degree in Materials Science in 2011 and a Ph.D. degree in Materials Science in 2014, both from the same university, under the supervision of A. Becerro. After completing his Ph.D., he worked as a postdoctoral fellow at the CEMHTI laboratory (CNRS-Orleans, France) for 2 years under the guidance of M. Allix and C. Bessada. He then conducted research as a postdoctoral researcher at the University of Limoges (Limoges, France) for one year (with G. Delaizir).

MSD received an MSci from the University of Cambridge and then a PhD under Ali Alavi in the quantum modelling of H transport through crystalline materials. As a PDRA with Mats Persson at the University of Liverpool he used DFT to study the adsorption of molecules on metal surfaces. In the group of Matt Rosseinsky he computationally modelled bulk crystalline oxides with applications in photocatalysis and fuel cells. He developed the University’s first crystal structure prediction package and expanded his research to other chemistries and to materials with widely varying applications.

Fabio Denis Romero did his doctoral work at the University of Oxford with Professor Michael Hayward on the Topochemical Synthesis of Novel Electronic Materials. He then did postdoctoral work at the University of Liverpool (UK) and the University of Kyoto (Japan). He is currently a CNRS researcher at the Institut Néel in Grenoble, France, working on the synthesis and characterisation of novel oxide and mixed anion materials.

 Ca2MnO3X - Oxyhalides with 1-dimensional ferromagnetic chains of square planar S = 2 Mn3+

Convinced of persistent phosphors beauty and potential for state-of-the-art nanotechnologies, Victor joined the Institute of Materials Science of Seville (Spain, 2020) to focus on their elaboration as thin transparent coatings and their optical environment modifications. He hopes that this transversal approach will boost afterglow as to allow him spending the longest time as possible in cool and dark rooms, waiting for afterglow to vanish.

The purpose of current study was green synthesis of silver nanoparticles (AgNPs) from seeds and wild Silybum plants in comparison with their respective extracts followed by characterization and biological potency. The biologically synthesized AgNPs were subjected to characterization using techniques like XRD, FTIR, TEM, HPLC and SPE. Highly crystalline and stable NPs were obtained using Silybum wild plant (NP1) and seeds (NP3) with size range between 18.12 and 13.20 nm respectively. The synthesized NPs and their respective extracts revealed a vast range of biological applications showing antibacterial, antioxidant, anti-inflammatory, cytotoxic and antiaging potencies. The highest antioxidant activity (478.23 ± 1.9 μM, 176.91 ± 1.3 μM, 83.5 ± 1.6% μgAAE/ mg, 156.32 ± 0.6 μgAAE/mg) for ABTS, FRAP, FRSA, TRP respectively was shown by seed extract (NP4) followed by highest value of (117.35 ± 0.9 μgAAE/mg) for TAC by wild extract (NP2). The highest antifungal activity (3 mm ± 0.76) against Candida albicans was shown by NP3 while antibacterial activity of (6 mm against Klebsiella pneumonia) was shown by NP3 and NP4. The highest anti-inflammatory activity (38.56 ± 1.29 against COX1) was shown by NP2. Similarly, the high value of (48.89 ± 1.34 against Pentosidine-Like AGEs) was shown by NP4. Also, the high anti-diabetic activity (38.74 ± 1.09 against α-amylase) was shown by NP4. The extracts and the synthesized NPs have shown activity against hepato-cellular carcinoma (HepG2) human cells. The HPLC analysis revealed that the highest value of silymarin component (silybin B 2289 mg/g DW) was found for NP4. Silydianin is responsible for capping. Among the green synthesized AgNPs and the extracts used, the effect of NP4 was most promising for further use.
