Metal forming processes are important technologies for the pro- duction of engineering structures. In order to optimize the result- ing material properties, it becomes necessary to simulate the entire forming process by taking into account physical…

We examined Cu contamination effects on macrobenthic communities and Cu concentration in invertebrates within Shelter Island Yacht Basin, San Diego Bay, California. Results indicate that at some sites, Cu in sediment has exceeded a threshold for…

Bonding of the neutral oxygen donor to metal ions is discussed in relation to metal ion selectivity. Important factors are (a) inductive effects of alkyl groups attached to the oxygen donor atom, so that donor strength increases H2O < ROH < R2O,…

Microorganisms in nature often live in surface-associated sessile communities, encased in a self-produced matrix, referred to as biofilms. Biofilms have been well studied in bacteria but in a limited way for archaea. We have recently characterized…

With the objective of correlating the anatomical aspects of the palato-gingival groove with its etiology, diagnosis, and alternative treatments, 13 permanent maxillary incisors with palato-gingival grooves were selected from a large sample and…

Metal hydrides, with their inherently high gravimetric and volumetric densities, present a compelling platform for hydrogen storage for mobile applications. However, several fundamental barriers have persistently impeded technological progress. This…

The magnetic coupled spin-torque device (MCSTD) is a new spintronics device architecture that is free from difficulties in spin transport and detection and uses spin torque transfer and magnetic coupling to modulate its energy barrier. Asymmetric…

Implant-associated infections are a challenging problem in surgery. Bacteria in biofilms are difficult to treat as they are less susceptible to antibiotics or antiseptics which require high drug concentrations at the site of infection. We present a…
-
In the field of molecular spintronics, the use of magnetic molecules for information technology is a main target and the observation of magnetic hysteresis on individual molecules organized on surfaces is a necessary step to develop molecular memory…

We report on nonepitaxially grown L10 Cu-alloyed FePt thin films with strong 001 texture. The FePt films with different Cu contents were deposited directly on Si wafers with a Fe49Pt51/Cu multilayer structure. The Cu content was varied from 0 to 13…

Magnetic properties of graded A1/L1[sub 0] films obtained by heat treatment of FePt/CoPt multilayersStructurallygradient layered A1/L10 films are obtained by heat treatment ofmagnetron sputter deposited FePt(20 nm)/CoPt(x nm) bilayers where x=0120 nm. Themagnetic properties can be tuned by adjustment of the layerthicknesses and taking advantage of…

Despite substantial research into smart materials and structures technology, the integration of magnetostrictive materials into fiber-reinforced polymer laminated structures to provide capabilities such as actuation has been limited to date. In this…

Since the introduction of the planar magnetron by J.S. Chapin in 1974 magnetron sputtering has become the most important technology for the deposition of thin films. Today it has conquered all industrial branches needing high-quality coatings for…
-
Magnetron sputtering has become the process of choice for the deposition of a wide range of industrially important coatings. Examples include hard, wear-resistant coatings, low friction coatings, corrosion resistant coatings, decorative coatings and…
