To improve the corrosion protection of copper metal, 0.01M concentration of 1H-1,2,4-triazole-3-thiol (TAT) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (GPTMS) and Tetraethoxysilane (TEOS). It was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. The TAT-doped hybrid sol-gel coating was applied over the c...
By varying the density of solution-processed lithium fluoride (sol-LiF) nanoparticles at the interface between tin-doped indium oxide (ITO) and poly(3,4ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), we have demonstrated that the electronic hole collection efficiency of an organic photovoltaic cell can be optimized through tuning the energy level alignment at the ITO/PEDOT:PSS inter...
beryllium oxide (beo) nanopowder was synthesized using sol-gel method and the effects of changes of chemical reagents were investigated. because of tissue equivalence and other outstanding thermoluminescence (tl) properties of the bulk material in x and γ dosimetry, the applicability of this nanostructure in tl dosimetry was studied following irradiation to the 137 c...
We propose a sign-based online learning (SOL) algorithm for a neuromorphic hardware framework called Trainable Analogue Block (TAB). The TAB framework utilises the principles of neural population coding, implying that it encodes the input stimulus using a large pool of nonlinear neurons. The SOL algorithm is a simple weight update rule that employs the sign of the hidden layer activation and th...
zro2 nanopowder was prepared by the sol-gel auto-combustion method. the product was characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). the average crystalline size of zro2 was obtained 62 nm. also, photocatalytic removal of nitrophenol from aqueous solution by using nanoscale zro2 under uv light irradiation was studied. th...
The present study was designed to examine fascicle-tendon interaction in the synergistic medial gastrocnemius (MG) and soleus (Sol) muscles during drop jumps (DJ) performed from different drop heights (DH). Eight subjects performed unilateral DJ with maximal rebounds on a sledge apparatus from different DH. During the exercises, fascicle lengths (using ultrasonography) and electromyographic act...
PURPOSE Skeletal muscle wasting is well documented in chronic heart failure (CHF). This article provides a more detailed understanding of the morphology behind this muscle wasting and the relation between muscle morphology, strength, and exercise capacity in CHF. We investigated the effect of CHF on lower limb lean mass, detailed muscle-tendon architecture of the individual triceps surae muscle...

a series of complexes of the type trans-[co(acacen)(amine)2]clo4, where (acacen) is the (bis(acetyleacetone) ethylenediimine) and the amines are benzyl amine (bzlan) 1, 2-amino pyrimidine (2ampy) 2, n-methylpipirazine (nmpip) 3, 3-methyl pyridine (3mpy) 4, p-toluidine (p-toldn) 5, has been synthesized and characterized by uv-vis. and ft-ir. the kinetics of the substitution reaction of [co(acace...
extracts of cotoneaster medicus, glycyrrhiza glabra, as endemic plants of iran, along with mixture of them were investigated for their antioxidant activities using 2, 2- diphenyl-1-picrylhidrazyl (dpph) reagent. uv-vis spectrophotometry method was used to evaluate the ability of cotoneaster and glycyrrhiza glabra antioxidant to scavenge dpph radical. the kinetic parameters such as rate constant...
