DuongLab

Dear all,

On behalf of the Organizing Committee of the Mini Interdisciplinary Student Symposium, we are honored and happy to welcome you to this event which will be held on March 26th, 2021 virtually at Université du Québec à Trois-Rivières. In this second edition, we are fortunate to welcome the huge number of researchers from various institutions in Colombia, Tunisia, Morocco, France, United States and Vietnam. The MISS 2021 is an opportunity to create exchanges of research work between partner countries with Québec. It is a great honor to welcome you to this event at Université du Québec à Trois-Rivières. In this year, the theme of the event will give priority to materials, energy, and their application.

We thank all visitors and exhibitors who share their work and research activities in chemistry, biochemistry, physics, material sciences and so forth. The notion of community is important for us, because it is the basis of the scientific process and the verification by our colleagues in vast fields of expertise. MISS 2021 shows that the scientific community has a real spirit of sharing and expanding knowledge that transcends borders.

We warmly thank the Ministère des Relations internationales et de la Francophonie, the Université du Québec à Trois-Rivières, the Institut de Recherche sur l’Hydrogène, the Department of chemistry, biochemistry and physics and the DuongLab team for their support to the realization of this event.

Adam Duong.

The DuongLab team is proud to share these discoveries with you, especially those related to the production of molecular hydrogen by photocatalytic means We have been honored by the publication of our work in the Journal of Inorganic Chemistry,  a journal of  The American Chemical Society .  We were all the more gratified by their invitation to make a cover page for our article.

The work led by Professor Adam Duong of the Hydrogen Research Institute has contributed to the development of Metal-Organic Frameworks (porous materials called IRHs) capable of capturing carbon dioxide and separating gases at atmospheric temperature and pressure.

By examining the crystal structures of the self-assemblies of 1H,1′H-[3,3′]bipyridinyl-6,6′-dione 1 and its coordination structure with CoIJII), to form novel CP-671, our study demonstrates the tendency of dipyridones to generate predictable patterns by hydrogen bonding depending on the crystallization conditions and the potential of pyridone ligating groups to design novel coordination polymers with structural diversity. The two structures of 1 elucidated by single-crystal X-ray diffraction show a cyclic dimer and zigzag chain to generate fascinating hydrogen bond frameworks. A two-dimensional coordination polymer structure (CP-671) is obtained by the linkage of 1 with a cobalt cation according to a known coordination mode of the 2-pyridone ligating group.

A new series of hydrogen-bonded metallotecton networks 6−9 of the general formula [M(2)2(NO3)2] were obtained from the reaction of 6-pyridin-2-yl-[1,3,5]-triazine-2,4-diamine 2 with transition-metal ions [M: Co(II), Ni(II), Cu(II), and Zn(II)]. Their supramolecular networks and associated properties were characterized by single-crystal and powder X-ray diffraction, IR, solid-state UV−vis spectroscopy, and thermogravimetric analysis associated with differential scanning calorimetry. On the basis of standard patterns of coordination involving 2,2′-bipyridine and simple derivatives, compound 2 binds transition-metal ions with predictable constitution and the diaminotriazinyl (DAT) groups serve orthogonally to ensure the intermetallotecton interactions by hydrogen bonding according to well-established motifs I−III. As expected, compound 2 formed octahedral 2:1 metallotectons with M(NO3)2, and further self-assembled by hydrogen bonding of the DAT groups to produce pure, crystalline, homogeneous, and thermally stable materials. 

Renewable energies remain the only alternative to fossil fuels. The development of clean and sustainable energies (solar, wind, hydro, etc.) has become more than essential. An important chain to increase the use of these inexhaustible energy resources is the development of advanced materials with efficient conversion and storage. Current projects give hope that one day we will be independent of polluting energies sources with high greenhouse gas. This seminar will address the energy issues and challenges related to energy conversion and storage to be achieved by 2050.
