phenolic resin is among the oldest thermoset resins that have found wide spread applications in several industries, largely due to its high thermal resistance. in this research, room temperature curing of phenolic resin and its reinforced silica composite has been investigated by p-toluene sulphonic acid as a catalyst. mechanical properties of the composites such as impact strength, flexural pr...
( ) Affinity-based re®ersed micellar extraction and separation ARMES has pro®en effecti®e in separating glycoproteins from nonglycosylated proteins from natural sources. The ability of ARMES to resol®e closely related glycoproteins is of paramount importance if ARMES is to be used in glycoform resolution. It is demonstrated that ARMES ( ) can resol®e the structurally similar soybean peroxidase ...
Highly ordered mesoporous polymer-silica and carbon-silica nanocomposites with interpenetrating networks have been successfully synthesized by the evaporation-induced triconstituent co-assembly method, wherein soluble resol polymer is used as an organic precursor, prehydrolyzed TEOS is used as an inorganic precursor, and triblock copolymer F127 is used as a template. It is proposed for the firs...
PP/EPDM Thermoplastic Vulcanizate (TPV) filled with carbon black (CB) has been prepared and the localization of filler in blend was observed to be dependent on crosslinking chemistry: rubber phase when EPDM crosslinked phenolic resin (resol) at interface dicumyl peroxide (DCP). It proved, based model reactions that mimicked what could happen during process high temperature, DCP led polymer chai...
This paper presents a new image sensor with programmable multiresol~~tion rearlout capability. The proposed image sensor can o11tp11t data at varying resolutions. Differing to our previollsly reported spatially variant snnlpling sensor which sub-samples witho ~ ~ t filtering[l], in the m~lltiresollltion sensor, 11locks of the pixels are averaged and read out then, the new sensor does not suffer...
In this paper , the effect of curing time and temperature as well as various primers on durability of high density polyethylene on plain carbon steel have been investigated. The aim is to increase adhesion, improve durability and also to produce a defect-free in order to improve the corrosion resistance of steel substrate. For this purpose, after surface preparation and applying a primer (zin...
