Research in biosensing currently occupies an important role among biomolecular detection techniques, especially with respect to medical diagnoses. Is this sense, the development of biosensors based on localized surface plasmon resonance (an optical transducer) or electrochemical transductions have been highlighted. However, and working together enable more versatile detections biosensing. Thus,...

Abstract Natural fiber-reinforced biocomposites displaying light weight, low thermal conductivity and reduced environmental footprint are increasingly relevant in structural, packaging, cementitious masonry materials. However, the poor interfacial compatibility between fibers typical polymers has limited development of mechanical strength water resistance. Here, we report a green, facile effect...

GO-NH2 (amino functionalized graphene oxide) was synthesized by grafting (3-aminopropyl) triethoxysilane onto the surface GO (graphene oxide). The with a higher area and many active sites characterized its effectiveness in removing Rhod B dye Ni(II) ions from wastewater adsorption observed. effects of pH, time, strange on efficiency were investigated. equilibrium isotherm data confirmed that it...

Conductometric sensors have been fabricated by applying imprinted polymers as receptors for monitoring engine oil quality. Titania and silica layers are synthesized via the sol-gel technique and used as recognition materials for acidic components present in used lubricating oil. Thin-film gold electrodes forming an interdigitated structure are used as transducers to measure the conductance of p...

Model samples of the interface of an adhesive joint containing small levels of aminopropyl triethoxysilane (APS) have been prepared in order to examine the interface formed with an aluminium substrate. X-ray photoelectron (XPS) and time of flight secondary ion mass spectrometry (ToF-SIMS) has been used to analyse and image the interface region in between the aluminium and an epoxy adhesive in o...

This work focuses on reactive extrusion to design polypropylene (PP) chains with long and short branching obtain non-linear behavior for the synthesis of low-density foams (<100 kg m?3) using a batch supercritical carbon dioxide (scCO2) foaming process. From maleic anhydride (MA) grafted PP (PP-g-MA), long-branched are performed [MA]/ [OH] reaction (with Sorbitol alcohol). On other hand, branch...

A new structure, consisting of a shell cross-linked, 2 nm size siloxane nanocage containing propylamine groups tethered to the interior face of the shell was synthesized, starting with micelles of the surfactant molecule, (triethoxysilyl)propylcetylcarbamate. After hydrolysis of the ethoxysilyl groups and condensation and capping of the silanols to form a cross-linked, one-atom-layer-thick silo...

This study evaluates the effectiveness of vapour-phase deposition for creating sub-monolayer coverage of aminopropyl triethoxysilane (APTES) on silicon in order to exert control over subsequent gold nanoparticle deposition. Surface coverage was evaluated indirectly by observing the extent to which gold nanoparticles (AuNPs) deposited onto the modified silicon surface. By varying the distance of...
