A series of monometallic Ru, Pd, and bimetallic Ru–Pd catalysts loaded on CeO2 support have been prepared via mechanochemical conventional incipient wetness impregnation methods used in the partial oxidation methane (POM) to obtain synthesis gas (H2 CO). The influence preparation method, order addition metals, Ru:Pd metal ratio, milling energy time for samples by evaluated between 300 600 °C. r...

Peridynamics (PD) is a nonlocal continuum theory based on integro-differential equations without spatial derivatives. The elongation fracture criterion is implicitly incorporated in the PD theory, and fracture is a natural outcome of the simulation. On the other hand, a new fracture criterion based on the crack opening displacement combined with peridynamic (PD-COD) is proposed. When the relati...

palladium (ii) coordination complexes catalyze the reaction of alcohols with ketones to yield ethers. during the catalytic cycle, the alcohol adds selectively to the β-carbon (anti-markovnikov). in this work, mechanism and kinetics for the reaction of methanol with methyl vinyl ketone (mvk), being catalyzed by pd, has been theoretically investigated in detail. using quantum mechanical approach,...

Early diagnosis of Parkinson’s Disease (PD) is crucial for effective neuroprotection and early management. Recent neuroimaging techniques such as dopaminergic imaging using Single Photon Emission Computed Tomography (SPECT) with 123 I-Ioflupane (DaTSCAN) have shown to detect even early stages of the disease. In this paper, we use the Striatal Binding Ratio (SBR) values that are calculated from ...

Programmed cell death 1 (PD-1) is an immunosuppressive receptor that transduces an inhibitory signal into activated T cells. Although a single nucleotide polymorphism in the gene for PD-1 is associated with susceptibility to systemic lupus erythematosus, the role of PD-1 in systemic lupus erythematosus is still not well understood. In this study, we used NZB/W F1 mice, a model of lupus-like nep...

Objective(s): Program death 1 (PD-1)/ program death-ligand 1 (PD-L1) pathways, as the main inhibitory checkpoints, induce immunosuppression in the tumor microenvironment (TME). Despite the importance of inhibitor checkpoint receptor (ICR) blockers, their outcomes have been limited by the low immune response rate and induced acquired resistance. Pre-existing tumor-speci...

Palladium is a frequently used model system for hydrogen storage. During the past few decades, particular interest was placed on the superior H-absorption properties of nanostructured Pd systems. In the present study nanoporous palladium (np-Pd) is produced by electrochemical dealloying, an electrochemical etching process that removes the less noble component from a master alloy. The volume and...

In many diseases such as cancer, simultaneous use of two or more pharmacologically active agents will be more effective and have fewer side effects. In this study a new palladium(II) complex with formula of [Pd(phen)(py-dtc)]NO3 (where is phen 1,10-phenanthroline and py-dtc is n-propyldithiocarbamate), was synthesized. The cytotoxic activity of this complex was tested against leukemia K562 cell...
