Oxygen evolution reaction (OER) is one of the most important anodic reactions in electrochemical conversion devices. Although a lot OER electrocatalysts have been developed, actual active sites during not fully understood. Herein, we report that distorted FeOOH/Ni hydroxide on Ni foam (NF) (d-FeOOH/Ni hydroxide-NF) shows better performance (1.50 V at 100 mA/cm2 and long-term stability for 32 h ...

Background: Regular walking in different types of footwear may increase the mediolateral shear force, knee adduction moment, or vertical ground-reaction forces that could risk early development osteoarthritis (OA). Purpose: To compare kinematic and kinetic parameters affect OA 3 conditions. Study Design: Controlled laboratory study. Methods: A total 40 asymptomatic participants performed trials...

a graph g is said to have a totally magic cordial labeling with constant c if there exists a mapping f : v (g) ∪ e(g) → {0, 1} such that f(a) + f(b) + f(ab) ≡ c (mod 2) for all ab ∈ e(g) and |nf (0) − nf (1)| ≤ 1, where nf (i) (i = 0, 1) is the sum of the number of vertices and edges with label i. in this paper, we give a necessary condition for an odd graph to be not totally magic cordial and ...

Neurofilaments (NFs) are a major constituent of nerve cell axons that assemble from three subunit proteins of low (NF-L), medium (NF-M), and high (NF-H) molecular weight into a 10 nm diameter rod with radiating sidearms to form a bottle-brush-like structure. Here, we reassemble NFs in vitro from varying weight ratios of the subunit proteins, purified from bovine spinal cord, to form homopolymer...

background: formaldehyde (h2c = o), is a member of aldehyde family with a simplest organic molecule, used in various industries. the aim of this experimental study was to investigate the effects of simultaneous formaldehyde and noise exposure on hormonal pituitary-gonadal axis in adult male mice. methods: 46 adult male mice were randomly assigned to one control group and three experimental grou...

objective(s): to study the effect of cardiopulmonary bypass (cpb) on nuclear factor-kappa b (nf-кb) and cytokine expression and pulmonary function in dogs. materials and methods: twelve male mongrel dogs were divided into a methylprednisolone group (group m) and a control group (group c). all animals underwent aortic and right atrial catheterization under general anesthesia. changes in pulmonar...
