in the present study, ptruce/mwnts nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (mor). to characterize the nanocatalysts, tem, xrd, eds and xps are investigated. cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activity and stability of the catalysts in methanol electro-oxi...

In this study, we used DFT calculations to investigate the bi-functional nature of Cu-based alloy nanoclusters (NCs) supported on CeO2(111) for CO oxidation. More specifically, we studied the reaction pathways on Cu3Pt7 and Cu3Rh7via the O2 associative (OCOO) and dissociative mechanisms. We find that CO oxidation on Cu3Pt7 proceeds via the O2 dissociation pathway, while Cu3Rh7 prefers the OCOO ...

tmrna (also known as ssra or 10sa rna) is so-named for its dual nature so that can function like trna and mrna. tmrna involved in a trans-translation reaction that truly is a kind of translational quality control system. this process contributes to the recycling of stalled translation complexes at the end of an mrna lacking a stop codon or at an internal mrna cluster of rare codons in a process...

stroke scales can be classified as clinicometric scales and functional impairment, handicap scales. all studies describing stroke scales were reviewed by internet searching engines with the final search performed on january 1, 2013. the following string of keywords was entered into search engines; stroke, scale, score and disability. despite advantages of modified national institute of health s...

Bi-specific antibodies (BsAbs), which can simultaneously block 2 tumor targets, have emerged as promising therapeutic alternatives to combinations of individual monoclonal antibodies. Here, we describe the engineering and development of a novel, human bi-functional antibody-receptor domain fusion molecule with ligand capture (bi-AbCap) through the fusion of the domain 2 of human vascular endoth...

This paper presents a linkage factors synthesis and multi-level optimization technique for bi-stable compliant mechanism. The linkage synthesis problem is modeled as multiple level factors and responses optimization problem with constraints. The bi-stable compliant mechanism is modeled as a crank slider mechanism using pseudo-rigid-body model (PRBM). The model exerts the large deflection of fle...
