Abstract:

Using self-consistent effective-medium theory, we studied the complex elastic compliances of conducting disordered heterogeneous piezoelectric-polymer systems. The considered system is a random mixture of piezoelectric spheroids and polymer ones with the same orientation. The proximate cause of the effective elastic constants frequency dependencies was considered. The nature of the obtained spectra was analyzed.

Abstract:

NMR spectroscopy continues to provide important molecular level details of dynamics in different polymer materials, ranging from rubbers to highly crosslinked composites. It has been argued that thermoset polymers containing dynamic and chemical heterogeneities can be fully cured at temperatures well below the final glass transition temperature (Tg). In this paper, we described the use of static solid-state 1H NMR spectroscopy to measure the activation of different chain dynamics as a function of temperature. Near Tg, increasing polymer segmental chain fluctuations lead to dynamic averaging of

Abstract:

Low oil extraction and early high water production are caused in part by reservoir heterogeneity. Huge quantities of water production are prevalent issues that happen in older reservoirs. Polyacrylamide polymer gel systems have been frequently employed as plugging agents in heterogeneous reservoirs to regulate water output and increase sweep efficiency. Polyacrylamide polymer gel systems are classified into three classes depending on their composition and application conditions, which are in-situ monomer gel, in-situ polymer gel, and preformed particle gel (PPG).

Abstract:

Melting models for flood fed single screw extruders, like the Tadmor model, describe the melting of pure thermoplastic polymers. However, the melting behavior of heterogenous polymer systems is of great interest for recycling issues, for example. In this work, the melting of polymer mixtures and that of pure bulk polymers by the drag induced melt removal principle is examined both theoretically and experimentally. The applied model experiments represent the melting of the solid bed at the barrel in single screw extruders. As polymer pellet mixtures, polypropylene-homopolymer mixed with polypro

Epoxides are very useful key intermediates in the construction of synthetically challenging molecules. Owing to their strategic importance in organic synthesis, novel polymer-supported iminium salts were investigated for the catalytic oxidation of unfunctionalised alkenes. A solid-phase methodology was initiated and then developed for the evaluation of several heterogeneous catalysts. In an initial approach, immobilised iminium salts were prepared by condensation of 2-(bromoethyl)benzaldehyde with commercially available aminomethyl resins. These materials were shown to be able to successfully

Abstract:

In order to truly understand the process-property behavior of polymer systems it is essential to identify the three dimensional structure of the materials fabricated. For heterogeneous polymer systems such as nanoparticle filled systems, determination of the three dimensional optical properties are particularly difficult. Such information is essential, however, if the behavior of these systems are to be understood and formalized. The purpose of the present research was to develop methods for measuring the optical characteristics of heterogeneous polymer systems nondestructively, in order to c

Abstract:

Abstract The majority of commercially available particulate materials in additive manufacturing are single-material systems. Multi-material systems are typically generated by bulk mixing as heterogeneous systems that are difficult to reproduce due to segregation effects during mixing and later deposition in the manufacturing process. This limits the properties of the additively manufactured components. For further application areas of additively manufactured components, it is therefore imperative to produce process-optimized single-material particles in addition to multi-material systems, wher

Abstract The history of Electrochemical Impedance Spectroscopy (EIS) is briefly reviewed, starting with the foundations laid by Heaviside in the late nineteenth century in the form of Linear Systems Theory (LST). Warburg apparently was the first to extend the concept of impedance to electrochemical systems at the turn of the nineteenth century, when he derived the impedance function for a diffusion process that still bears his name. Impedance spectroscopy was next employed extensively using reactive bridges to measure the capacitance of ideally polarizable electrodes (mostly mercury), leading

Abstract It is recognised that chemical interactions between scale inhibitor (SI) and corrosion inhibitor (CI) result in a reduction in the performance efficiency of both chemicals. As reservoir production systems become ever more complex, the requirements for chemical compatibility become greater. This is a particular concern for satellite and deepwater fields in which several wells may be co-produced through very long subsea tie backs. In such systems, chemical / chemical performance compatibilities are essential. Previous work on the issue has mainly been limited to field specific studies w

Abstract Heterogeneous sandstone reservoirs pose many challenges to oil recovery, one of them being recovering oil from the low permeability zones. Low-tension-gas (LTG) flooding has been proven to be effective in mobilizing oil trapped in low permeability reservoirs.

The objective of this study is to maximize oil recovery in a high-temperature, high salinity, and heterogeneous sandstone reservoir by LTG flooding with the assistance of a polymeric gel for conformance control.

Abstract:

Highly cross-linked polyurethanes have a high elastic modulus and creep resistance, but they undergo a brittle fracture below the glass transition temperature. Unfortunately, a large number of glassy polyurethanes are prone to brittle fracture without undergoing large elastic deformations; in particular, brittle failure is common under conditions such as low temperature and high strain rates. While the rigidity in polymers is required for practical applications, the lack of resistance against crack propagation is essential to avoid catastrophic failures. The toughening of polymers is a crucial
