“…The observed decrease in the hydrogenation rate is attributable to the suppression of PdH x hydride phase (see Figure 5 ) due to the intensive formation of PdIn alloy enriched in Pd as indicated by XRD data (see Insert of Figure 2 , pattern 4). Note, that similar effect was discussed by several authors for Pd catalysts modified with Zn [ 8 ], Ag [ 30 , 31 ], Sn, Sb, Ge, Pb [ 53 ], Ga [ 59 ]. In our previous study, this effect was also observed for PdIn/SiO 2 catalyst [ 51 ].…”

“…Moreover, unlike homogeneous catalysts, the presence of a variety of active sites on their surface significantly reduces selectivity in catalytic reactions. Therefore, in recent years, highly-ordered intermetallic compounds (IMCs) have attracted significant attention as a possible alternative to substitutional alloys in catalysis [ 2 , 4 , 5 , 6 , 7 , 8 ]. By general definition intermetallic compound is a chemical compound consisting of two or more metallic elements, which exhibits a highly ordered crystal structure different from the constituting elements [ 1 ].…”

Formation of PdIn intermetallic nanoparticles supported on α-Al2O3 was investigated by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and hydrogen temperature-programmed desorption (H2-TPD) methods. The metals were loaded as heterobimetallic Pd(μ-O2CMe)4In(O2CMe) complex to ensure intimate contact between Pd and In. Reduction in H2 at 200 °C resulted in Pd-rich PdIn alloy as evidenced by XRD and the disappearance of Pd hydride. A minor amount of Pd1In1 intermetallic phase appeared after reduction at 200 °C and its formation was accomplished at 400 °C. Neither monometallic Pd or in nor other intermetallic structures were found after reduction at 400–600 °C. Catalytic performance of Pd1In1/α-Al2O3 was studied in the selective liquid-phase diphenylacetylene (DPA) hydrogenation. It was found that the reaction rate of undesired alkene hydrogenation is strongly reduced on Pd1In1 nanoparticles enabling effective kinetic control of the hydrogenation, and the catalyst demonstrated excellent selectivity to alkene.

Immunosuppression derived after cytostatics application in cancer chemotherapy is considered as an adverse side effect that leads to deterioration of quality of life and risk of infectious diseases. A linear sulfated (1→3)-α-l-fucan M-Fuc prepared by chemical modification of a fucoidan isolated from the brown seaweed Chordaria flagelliformis, along with two structurally related synthetic sulfated oligosaccharides, were studied as stimulators of hematopoiesis on a model of cyclophosphamide immunosuppression in mice. Recombinant granulocyte colony-stimulating factor (r G-CSF), which is currently applied in medicine to treat low blood neutrophils, was used as a reference. Polysaccharide M-Fuc and sulfated difucoside DS did not demonstrate significant effect, while sulfated octasaccharide OS showed higher activity than r G-CSF, causing pronounced neutropoiesis stimulation. In addition, production of erythrocytes and platelets was enhanced after the octasaccharide administration. The assessment of populations of cells in blood and bone marrow of mice revealed the difference in mechanisms of action of OS and r G-CSF.
