  • Broad Spectrum Deubiquitinase Inhibition Induces Both Apoptosis and Ferroptosis in Cancer Cells. [Journal Article]
    Front Oncol. 2020; 10:949.Yang L, Chen X, … Liu J
  • Proteasomal deubiquitinase (DUB) inhibition has been found to be effective in experimental cancer therapy by inducing proteasome inhibition and apoptosis. Ferroptosis is a form of regulated cell death characterized by an iron-dependent lipid peroxidation. Antioxidant enzyme glutathione peroxidase 4 (GPX4) plays a key role in blocking ferroptosis through directly reducing phospholipid hydroperoxid…
  • Investigating lattice strain impact on the alloyed surface of small Au@PdPt core-shell nanoparticles. [Journal Article]
    Nanoscale. 2020 Apr 30; 12(16):8687-8692.Williams BP, Yaguchi M, … Tsung CK
  • We investigated lattice strain on alloyed surfaces using ∼10 nm core-shell nanoparticles with controlled size, shape, and composition. We developed a wet-chemistry method for synthesizing small octahedral PdPt alloy nanoparticles and Au@PdPt core-shell nanoparticles with Pd-Pt alloy shells and Au cores. Upon introduction of the Au core, the size and shape of the overall nanostructure and the comp…
  • Categorization of atomic mixing patterns in bimetallic nanoparticles by the energy competition. [Journal Article]
    Phys Chem Chem Phys. 2020 Apr 15; 22(15):7787-7793.Yun K, Nam HS, Kim S
  • The superior properties of bimetallic nanoparticles are strongly related to their morphology. A better understanding of the morphological details would be the first step to design bimetallic nanoparticles for target applications. In this study, we discussed three possible categories of the atomic mixing patterns of bimetallic nanoparticles using the concept of competition between bond energy and …
  • Production of Biogenic Nanoparticles for the Reduction of 4-Nitrophenol and Oxidative Laccase-Like Reactions. [Journal Article]
    Front Microbiol. 2019; 10:997.Capeness MJ, Echavarri-Bravo V, Horsfall LE
  • Biogenic nanoparticles present a wide range of possibilities for use in industrial applications, their production is greener, they can be manufactured using impure feedstocks, and often have different catalytic abilities compared to their chemically made analogs. Nanoparticles of Ag, Pd, Pt, and the bi-elemental PdPt were produced by Morganella psychrotolerans and Desulfovibrio alaskensis and wer…
  • Atomic Surface Segregation and Structural Characterization of PdPt Bimetallic Nanoparticles. [Journal Article]
    Materials (Basel). 2018 Oct 02; 11(10)Rodríguez-Proenza CA, Palomares-Báez JP, … Esparza R
  • Bimetallic nanoparticles are of interest since they lead to many interesting electrical, chemical, catalytic, and optical properties. They are particularly important in the field of catalysis since they show superior catalytic properties than their monometallic counterparts. The structures of bimetallic nanoparticles depend mainly on the synthesis conditions and the miscibility of the two compone…
  • Synthesis, Characterization, and Antimicrobial Activity of Novel Sulfonated Copper-Triazine Complexes. [Journal Article]
    Bioinorg Chem Appl. 2018; 2018:2530851.Katugampala S, Perera IC, … Perera T
  • Metallotriazine complexes possess interesting biological and medicinal properties, and the present study focuses on the synthesis, characterization, and antimicrobial activity of four novel copper-triazine derivatives in search of potent antibacterial and antifungal drug leads. In this study, 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-4,4'-disulfonic acid monosodium salt (L1, ferrozine) and 3-(2-p…
  • Bimetallic Pd-Pt alloy nanocluster arrays on graphene/Rh(111): formation, stability, and dynamics. [Journal Article]
    Phys Chem Chem Phys. 2018 Aug 22; 20(33):21294-21301.Düll F, Bauer U, … Papp C
  • Alloy catalysts have, in many cases, superior properties compared to their single metal counterparts. To gain deeper insights, we used graphene-supported bimetallic nanocluster arrays as a model system. We investigated the site occupation and the dynamic behavior of the metal distribution during adsorption and thermal treatment of CO layers on PdPt alloy nanocluster arrays supported on the graphe…
  • Synthesis, Characterization, and BSA-Binding Studies of Novel Sulfonated Zinc-Triazine Complexes. [Journal Article]
    Bioinorg Chem Appl. 2018; 2018:7563820.Abeydeera N, Perera IC, Perera T
  • Four Zn(II) complexes containing a pyridyl triazine core (L1 = 3-(2-pyridyl)-5,6-di(2-furyl)-1,2,4-triazine-5',5″-disulfonic acid disodium salt and L2 = 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine-4',4″-disulfonic acid sodium salt) were synthesized, and their chemical formulas were finalized as [Zn(L1)Cl2]·5H2O·ZnCl2 (1), [Zn(L1)2Cl2]·4H2O·2CH3OH (2), [Zn(L2)Cl2]·3H2O·CH3OH (3), and [Zn(L2)2Cl2] (4…
