single-walled carbon nanotubes (swcnt) and multi-walled carbon nanotubes(mwcnt) were melt-blended with polyvinylidene fluoride (pvdf).ft-ir technique revealed that swcnt has insignificant effect on the crystalline structure of pvdf and at 3wt% modification only 14% beta crystal isformed. this observation was accounted for by the chair structure of swcnt. in mwcnt nancomposites it was found that...

The shear behavior of polymers obtained by means of devices such as capillary and cone-and-plate rheometers is commonly used to assess their processing performance and as a characterization tool. However, the number of instances when two polymers have the same shear properties but perform differently during certain types of processing operations (e.g. film blowing and sheet extrusion) indicate ...

We report a novel method to prepare soft colloids with well-controlled softness. The softness of the colloids was characterised by atomic force microscopy and rheometry. Possible applications of such soft colloids in uniform particle coatings are demonstrated.

This paper is an attempt to develop a unifying algebraic framework for extensional theories capturing formally the informal concept of extensionality, as well as a generic automated proving technique, called extensional rewriting, that can be instantiated and then used to prove equational properties in various particular extensional theories.

In this paper we propose an approach for the extensional integration of data sources with heterogeneous representation formats. The proposed approach is based on the exploitation of a new model, called E-SDR-Network, for representing and handling, at the extensional level, heterogeneous data sources, ranging from databases to XML documents, OEM graphs and other semi-structured data. Due to the ...

This paper introduces a procedure that takes a simple version of extensional semantics and generates from it an equivalent possibleworld semantics that is suitable for treating intensional phenomena in natural language. This process of intensionalization allows to treat intensional phenomena as stemming exclusively from the lexical meaning of words like believe, need or fake. We illustrate the ...

The rheological properties of acid hydrolyzed corn stover at high solids concentration (20-35 wt.%) were investigated using torque rheometry. These materials are yield stress fluids whose rheological properties can be well represented by the Bingham model. Yield stresses increase with increasing solids concentration and decrease with increasing hydrolysis reaction temperature, acid concentratio...

The importance of clarifying the goals of a cryptographic protocol is widely recognised. The majority of authors have addressed intensional goals which are concerned with correct operation within the protocol itself. Extensional goals are properties independent of the protocol and deene what the protocol is designed to achieve. This paper reviews the previous literature on goals in protocols an...

It is well known that the extensional axiom of choice (ACext) implies the law of excluded middle (EM). We here prove that the converse holds as well if we have the intensional (‘type-theoretical’) axiom of choice ACint, which is provable in Martin-Löf’s type theory, and a weak extensionality principle (Ext−), which is provable in Martin-Löf’s extensional type theory. In particular, EM ⇔ ACext h...
