A comparison on physical, structural, and photocatalytical properties of TiO2 nanopowders produced using sol-gel and flame spray pyrolysis
(2013)
In this study, nanoscale photocatalyst TiO2 powders were synthesized via sol-gel and flame spray pyrolysis (FSP). Phase structures and ratios were analyzed by X-ray diffractometer (XRD). Size, specific surface area, and ...
The thermodynamic stability of intermediate solid solutions in LiFePO4 nanoparticles
(Royal Society of Chemistry, 2016)
Theoretical predictions from first principles and recent advances in in situ electrochemical characterization techniques have confirmed the presence of solid-solution states during electrochemical (de)lithiation of LiFePO4 ...
Particle-size and morphology dependence of the preferred interface orientation in LiFePO4 nano-particles
(Royal Society of Chemistry, 2014)
We gain new insights into the equilibrium properties and potential two-phase lithiation mechanisms in LiFePO4 nano-particles by conducting a first-principles investigation of the anisotropic chemical interfacial energy ...
Modified ultrasound despeckling assessment index for the Field II simulated cyst image
(Institution of Engineering and Technology, 2017)
Various methods have been proposed to reduce speckle noise, which decreases image quality in ultrasound images. The Field II simulated cyst image consists of three classes and is used to compare a proposed despeckle filter ...
2-Isopropenyl-2-oxazoline: A versatile monomer for functionalization of polymers obtained via RAFT
(2012)
2-Isopropenyl-2-oxazoline (iPOx) was polymerized for the first time via a controlled radical polymerization technique. Reversible addition-fragmentation chain transfer (RAFT) polymerization utilizing a dithiobenzoate-based ...
Comparison of the curing kinetic behavior for two epoxy resin systems containing EPIKOTE 828-EPIKURE 3090 and DURATEK KLM 606a-DURATEK KLM 606b
(2007)
The aim of the study is to determine the optimum cure temperatures and kinetics for two different epoxy resin systems without using solvent. Two resin systems consist of EPIKOTE 828® epoxy resin-EPIKURE® 3090 polyamidoamine ...
Estimation of the Bond grindability index from chemical analysis values and modulus of mixture of raw material of marls
(ICE Publishing Ltd., 2012)
In this study, the relationships between Bond grindability index (G bg) and chemical constituents were investigated on marl samples from the AS cement factory (Burdur/Turkey). First, standard Bond grindability tests were ...
An experimental investigation of heat transfer enhancement in a rectangular duct with plate fins
(2009)
In this study, using an ideal heat exchanger model, a detailed evaluation of performance parameters in the turbulent regime for the enhancement of heat transfer by using winglet-type vortex generators is carried out. The ...
Predicting microstructure evolution during directed energy deposition additive manufacturing of Ti-6Al-4V
(American Society of Mechanical Engineers (ASME), 2018)
Laser engineering net shaping (LENS) is one of the representative processes of directed energy deposition (DED) in which a moving heat source having high-intensity melts and fuses metal powders together to print parts. The ...
Large bandwidth mode order converter by differential waveguides
(Optical Society of American (OSA), 2015)
In this article, we propose a large bandwidth mode-order converter design by dielectric waveguides with equal lengths but different cross-sectional areas. The efficient conversion between even and odd modes is verified by ...
