Effectiveness of Ni incorporation in iron oxide crystal structure towards thermochemical CO2 splitting reaction
(
Elsevier Ltd
, 2017 , Article)
In this study, Ni-doped iron oxide (NixFe3−xO4) materials were synthesized via the 1,2-epoxypropane assisted sol-gel method by varying the molar concentration of Ni from x=0.2 to 1. Sol-gel derived NixFe3−xO4 gels were ...
Study of ethanol dehydrogenation reaction mechanism for hydrogen production on combustion synthesized cobalt catalyst
(
Elsevier Ltd
, 2017 , Article)
Cobalt nanoparticles synthesized via solution combustion synthesis were used to study the decomposition mechanism of ethanol for hydrogen production. Thermodynamic studies were conducted on the synthesis of cobalt nanoparticles ...
Influence of initial biomechanical environment provided by fibrous composite intramedullary nails on bone fracture healing
(
Elsevier Ltd
, 2017 , Article)
Long bone fractures are primarily treated with internal fixation devices, and intramedullary (IM) nails are the most commonly used. Reamed and unreamed surgical procedures are commonly used to attach IM nails to fractured ...
A two-level optimization approach for robust aircraft routing and retiming
(
Elsevier Ltd
, 2017 , Article)
We investigate the Robust Aircraft Routing and Retiming Problem that is defined as follows. Given a set of flight legs to be served by a set of aircraft fleets, together with a tentative schedule, the problem requires ...
Nonlinear thermal buckling of axially functionally graded micro and nanobeams
(
Elsevier Ltd
, 2017 , Article)
In this study, the nonlinear thermal buckling of axially functionally graded (AFG) Euler-Bernoulli micro/nanobeams is analyzed. The Eringen's nonlocal elasticity theory is used to develop the governing equations of nanobeam ...
Random number of units for K-out-of-n systems
(
Elsevier Inc.
, 2017 , Article)
This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ...
Investigation of the tribological and biomechanical properties of CrAlTiN and CrN/NbN coatings on SST 304
(
Elsevier Ltd
, 2017 , Article)
This study examines the influence of thin layer coatings of CrAlTiN and CrN/NbN, deposited via physical vapor, on the biocompatibility, mechanical, tribological, and corrosion properties of stainless steel 304. The ...
Filler strengthening of foam-filled energy absorption devices using CFRP beams
(
Elsevier Ltd
, 2017 , Article)
The crashworthiness of fiber reinforced plastics (FRP) is attracting more interest as they are currently contributing to several industries. In the present study, internally strengthened foam-filled rectangular carbon fiber ...
Investigation of lanthanum impregnated cellulose, derived from biomass, as an adsorbent for the removal of fluoride from drinking water
(
Elsevier Ltd
, 2017 , Article)
High concentrations of fluoride in drinking water can cause the disease fluorosis. Our scope goal is to develop an effective biopolymeric adsorbent for the removal of fluoride to below a specific safety limit set by the ...
Effect of composite intramedullary nails (IM) on healing of long bone fractures by means of reamed and unreamed methods
(
Elsevier Ltd
, 2017 , Article)
Complications are common during bone fracture healing owing to incompatibility of the implants. Flexible fibrous composite materials are promising materials that offer excellent biomechanical compatibility. Flexible composite ...
