We evaluated the effect of polyelectrolyte complexes (PEC) with varying balance of charges on the flocculation of precipitated calcium carbonate (PCC) particles. PECs composed of polyacrylamides carrying opposite charges (A-PAM and C-PAM) were investigated in terms of PCC floc shear resistance and re-flocculation effects. Light transmission was used in real time to monitor the dynamics of flocc...

In an increasingly connected world, security is a top concern for Internet of Things (IoT). These IoT devices have to be inexpensive implying that they will be constrained in storage and computing resources. In order to secure such devices, highly efficient public key cryptosystems (PKC) are critical. Elliptic Curve Cryptography (ECC) is the most commonly implemented PKC in use today. In this p...

Nanomultiple CaFe2O4/ZnFe2O4pn junctions are prepared by a pulsed laser deposition method to explore their photoelectrochemical properties as the photoelectrodes. It is demonstrated that the multiple-pn-junction structure is favorable to enhancing the photocurrent density and the onset potential of the photoelectrode. Furthermore, the 20-junction photoelectrode-based PEC cell yields a high open...

In recent decades, three generations of thiomers have been developed with the main purpose obtaining enhanced interactions mucosal tissues. Therefore, many different types thiolated ligands generated and attached to polymeric backbones. The aim this study was synthesize all directly compare their properties regarding mucus penetration mucoadhesion. Starting from pectin, unprotected thiomer pect...

Abstrac t Pulsed eddy current (PEC) is a new technique of non-destructive material evaluation (NDE). In comparison with other eddy current techniques, PEC uses pulsed excitation that is characterized by wide frequency content and thus the response carries more complex information about a tested object. PEC method is used in many NDE common applications such as inspection of defects, measurement...

The optical, morphological and photoelectrochemical (PEC) properties of transition metal oxide semiconductors are important to understand their influence on water oxidation performance. Herein, we provide experimental evidences for a better understanding of the factors that dictate the interactions of Sn-diffusion doping on the PEC properties of Fe2O3 photoanodes fabricated at high temperature ...

Abstract Special propylene-ethylene copolymer (PEC) and polypropylene (PP) fiber grade materials were blended through the melt-compounding method to prepare PP/PEC blends in varying proportions. Subsequently, further analysis was carried out on crystallinity, dispersibility, mechanical properties flexibility of blends. The results haven shown that PEC is uniformly dispersed PP matrix, whereas s...

This article describes the growth of Cu oxides films using reactive sputtering and application of CuO photocathode in semitransparent photoelectrochemical cell (PEC). In this data article, physical, optical and electrical...

inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. the present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (pec) based microparticles containing antibacterials for the treatment of lung infections.chitosan polyelectrolyte complex...

Corrosion is one of the important factors in equipment failures. Wall thinning can be used to evaluate corrosion conditions. However, most of equipments are coated with insulations in order to elevate the energy efficiency. Pulsed eddy current (PEC) testing technique can be used to measure wall thinning through insulation. But when the insulation outside is wrapped with galvanized steel, PEC si...
