Replacement policies for a parallel system with shortage and excess costs
(
Elsevier Ltd
, 2016 , Article)
It has been assumed in most maintenance models that (i) the number of units for a parallel system can be predefined precisely, (ii) maintenance cost after failure should be avoided, and (iii) age replacement can always be ...

Flexible NO2 sensors from renewable cellulose nanocrystals/iron oxide composites
(
Elsevier
, 2016 , Article)
A bio-friendly nanostructured cellulose nanocrystal (CNC) sheet with iron oxide grown on it acting as a nitrogen dioxide (NO2) gas sensor was fabricated by hydrothermal method. The structural investigation was done to ...
Propagation rate coefficient for sulfobetaine monomers by PLP-SEC
(
Elsevier Ltd
, 2016 , Article)
Zwitterionic polymers have been extensively used in the biomedical field, however, the knowledge about the kinetics and mechanism of radical polymerization of their monomers is limited. This work introduces the first ...
Corrosion protection of electrospun PVDF-ZnO superhydrophobic coating
(
Elsevier B.V.
, 2016 , Article)
A one-step electrospinning technique was used to prepare a protective superhydrophobic PVDF–ZnO nanocomposite coating for aluminum against corrosion. The wettability and morphology of the prepared coating surfaces was ...
