Surface treated fly ash filled modified epoxy composites

open access: yesPolímeros, 2015
Fly ash, an inorganic alumino silicate has been used as filler in epoxy matrix, but it reduces the mechanical properties due to its poor dispersion and interfacial bonding with the epoxy matrix.

THM and HAA formation from NOM in raw and treated surface waters [PDF]

open access: yes, 2017
The disinfection by-product (DBP) formation potential (FP) of natural organic matter (NOM) in surface water sources has been studied with reference to the key water quality determinants (WQDs) of UV absorption (UV254), colour, and dissolved organic ...

Mapping physicochemical surface modifications of flame-treated polypropylene

open access: yeseXPRESS Polymer Letters, 2014
The aim of this work was to investigate how the surface morphology of polypropylene (PP) is influenced by the surface activation mediated by a flame obtained using a mixture of air and propane under fuel-lean (equivalence ratio φ = 0.98) conditions ...

Improving the surface properties of an UHMWPE shoulder implant with an atmospheric pressure plasma jet [PDF]

open access: yes, 2018
Insufficient glenoid fixation is one of the main reasons for failure in total shoulder arthroplasty. This is predominantly caused by the inert nature of the ultra-high molecular weight polyethylene (UHMWPE) used in the glenoid component of the implant ...

Effect of fibre treatments on interfacial shear strength of hemp fibre reinforced polylactide and unsaturated polyester composites [PDF]

open access: yes, 2011
Surface treatment of hemp fibres was investigated as a means of improving interfacial shear strength (IFSS) of hemp fibre reinforced polylactide (PLA) and unsaturated polyester (UPE) composites. Fibres were treated with sodium hydroxide, acetic anhydride,
