de Senna Junior L, Pancotti A, Kilian A, de Siervo A, Diehl R, de Weerd M, et al.
Phys Chem Chem Phys . 2023 Jan; 25(4):3387-3394. PMID: 36633439
The intermetallic AlCo is defined as a structurally complex material and is considered a low-order quasicrystalline approximant. A single crystal of AlCo(001) was obtained by the Czochralski method. The sample...

Kadok J, de Weerd M, Boulet P, Fournee V, Ledieu J
Acta Crystallogr B Struct Sci Cryst Eng Mater . 2020 Aug; 75(Pt 1):49-52. PMID: 32830777
Following the recent determination of the AlAuIr structure, a new ternary phase has been identified in the Al-Au-Ir phase diagram. It has a chemical composition Al(Au;Ir) with an apparently low...

Sci Technol Adv Mater . 2019 Jul; 20(1):557-567. PMID: 31258823
Complex intermetallic compounds such as transition metal (TM) aluminides are promising alternatives to expensive Pd-based catalysts, in particular for the semi-hydrogenation of alkynes or alkadienes. Here, we compare the gas-phase...
