A label-free ultrasensitive impedimetric biosensor with lectin immobilised on graphene oxide (GO) for the detection of glycoproteins from 1 aM is shown here. This is the first time a functional lectin biosensor with lectin directly immobilised on a graphene-based interface without any polymer modifier has been described. The study also shows that hydrophilic oxidative debris present on GO has a...

Roadways are considered one of the most important elements of infrastructure and they play an essential role in our daily lives. In road pavement construction, the use of crumb rubber in the modification of bitumen binder is considered as a smart solution for sustainable development by reusing waste materials. It is believed that crumb rubber modifier (CRM) could be one of the alternative polym...

The article presents the results of research on production polymer-bitumen binder (PBB) based mixtures non-oxidized and oxidized petroleum products, namely high-viscosity tar, darkened vacuum distillate, bitumen 70/100, obtained at technological installations Limited Liability Partnership (LLP) “JV Caspi Bitum’’ styrene-butadiene-styrene (SBS) block copolymer brand L 30-01A modifier in presence...

In previous part of this work factors influencing the thermal stability of polymer nanocomposite materials were indicated, such as chemical constitution of organic modifier, filler content, nanocomposites’ structure and the processing-dependent degree of homogenization of nanofiller, were presented. In this part the basic changes in thermal behaviour of different polymeric matrixes (e.g. polyol...

the effect of impact modifier on creep behavior of wood flour- recycled polypropylene composites has been evaluated in this work. for this purpose, impact modifier (ethylene vinyl acetate) and recycled polypropylene were mixed with wood flour (50/50% w/w) as well as the impact modifier (0, 3%, 6% and 9%) by a counter-rotating twin-screw extruder to manufacture the wood flour- recycled polypropy...

This study reports on the synthesis of zinc oxide (ZnO) nanostructures and examines the performance of polymer nanocomposites fabricated using ZnO dispersed in polymer host matrices. The polymer matrix used was an epoxy based thermosetting polymer known as Diglycidyl Ether of Bisphenol-A(DGEBA). Zinc oxide nano particles were prepared by precipitation method using Poly Vinyl Alcohol as the surf...

Background and purpose of study: In the present investigation, an attempt was made to increase therapeutic effectiveness, reduce dose frequency and improvement in patient compliance, by developing sustained release matrix tablets of Diclofenac sodium using tamarind gum as release modifier. Methods: Six batches of sustained release matrix tablets of Diclofenac sodium were prepared by using diffe...

Multifunctional conductive binders represent an emerging class of polymer materials to address inherent challenges Si electrodes for high capacity lithium-ion batteries. Advanced with oriented functionalities are greatly desired facilitate the battery chemistry. We here report stable cycling a practical composite anode comprising industrial available SiO x (>60 wt%), carbon and binder—poly(9...

The aim of this paper is to investigate the tribological conditions required obtain low friction with a diblock PIB-PEG polymer modifier (PFM) blended in base oil (PAO4 + 1% wt PFM) under severe lubrication regime. Two conditions, rolling/sliding and reciprocating pure sliding, were investigated. A very coefficient (μ ~ 0.035) was obtained at temperature 100 °C whatever tribometer used. ECR mea...
