Marine structures are one of the most important and susceptible facilities in Iran due to corrosion. The two methods of Cathodic Protection, namely, the cathodic protection with sacrificial anodes and cathodic protection using impressed current, are widely used for corrosion protection. According to the former, sacrificial anodes are installed at several points in the structure. Position of the...

The botanical identification of Ulluchu, an iconic fruit frequently depicted in the art of the pre-Columbian Moche culture that flourished from A.D. 100-800 on the Peruvian north coast, has eluded scientists since its documentation in ceramics in the 1930s. Moche fine-line drawings of Ulluchu normally depict seed-pods or seeds floating in the air in sacrificial scenes, associated with runners a...

Transmission electron microscopy (TEM) was performed to study the microstructural evolution in Al–Cu–Fe quasicrystalline thin films. Thin films were grown by magnetron sputtering on sodium chloride crystals, which were subsequently dissolved in water to acquire free-standing films. Studies were conducted on the as-deposited sample, and samples that were annealed at 400 8C in Argon and 500 8C in...

Fractional flow analysis confirms the advantages of surfactant alternative gas injection (SAG) in enhanced oil recovery, but an adsorption phenomenon that has been affected by several factors, weakens the effectiveness of SAG injection. In this study, the effects of sacrificial agent, gas phase, and surfactant concentration on adsorption density on silica mineral were investigated by static and...

A strategy for the fabrication of high surface area poly(3-hexylthiophene) thin films by removal of nanoscale domains formed from graft copolymers is presented. This approach relies on the synthesis and characterization of cleavable graft copolymers based on regioregular poly(3-hexylthiophene) (rr-P3HT) main chain and sacrificial poly(styrene) side chains. An alkoxyamine initiator based on 2,2,...

Carbon nanotube paper, sometimes referred to as bucky paper, is a random arrangement of carbon nanotubes meshed into a single robust structure, which can be manipulated with relative ease. Multi-walled carbon nanotubes were used to make the nanotube paper, and were subsequently modified with platinum using an electroless deposition method based on substrate enhanced electroless deposition. This...

Sacrificial etching is one of the most important process steps in micro-electro-mechanical systems technology, since it enables the generation of free-standing structures. These structures are often the main part of micro-mechanical devices, intended to sense or induce a mechanical movement. The etching process transforms an initial multi-segmented geometry and depends on material properties an...

Although ‘the Lamb’ is the most important designation for Jesus Christ in the book of Revelation, the full significance of this sacrificial metaphor is still uncertain. In recent years, some scholars have given up looking for specific allusions to the OT sacrificial cult. However, little scholarly attention has been given to OT cultic allusions which surround the Lamb in the liturgical setting ...

We present a new technique allowing us to build freely suspended two-dimensional electron gases from AlGaAs/GaAs/AlAs heterostructures. This technique relies on an MBE-grown structures that includes a sacrificial layer. ( 1998 Elsevier Science B.V. All rights reserved.

Radical-induced addition-fragmentation processes were efficiently used for surface modification of fumed silica, and Z-supported solid CTAs could be reused in presence of excess sacrificial thermal initiator.
