Magnetic nanorings have unique closed-flux vortex states that exhibit no stray field. The chirality of the vortex can be used to represent a "1" or a "0" in magnetic bits for data storage purposes. Atomic Force Microscopy ...

Understanding domain wall (DW) motion in nanoscale ferromagnetic structures reveals intriguing physics, with tremendous potential applications in logic devices and racetrack memory. Work has been done to move a series of ...

Nanoscale devices are promising for the next generation of electronics, providing possibilities for greater hard drive storage capacity and higher computer execution speed. There are many strategies to produce such devices, ...

Biofilms are matrix-enclosed microbial communities that grow at interfaces. They are highly robust and exhibit significant phenotypic changes that render them resistant to many antibacterial agents that can kill their ...

Photo-crosslinkable hydrogel films are versatile materials for controlled drug delivery devices (Duncan, 2003), three-dimensional micro-assemblies, and components in microfluidic systems (Beebe et al., 2000). A hydrogel ...

A solar cell is a device that converts light energy into electrical energy. Solar cells hold plenty of potential in becoming a more widely available source of electricity that makes economic sense. However, improvements ...

Colloidal semiconductor nanocrystal quantum dots (QDs) have been a subject of interest for many years due to their favorable optoelectronic properties arising directly from their small size through quantum confinement ...

γ-Fe2O3 maghemite nanoparticles were synthesized via the homogeneous thermal decomposition of iron pentacarbonyl. This synthesis took place in the presence of a capping molecule, octanoic acid, and a mild oxidant, ...

In this study we investigated two polymeric reaction systems to fabricate stiffness-tunable and surface-modifiable polydimethylsiloxane (PDMS), a biomaterial commonly used in microfluidic devices for medical diagnostics ...
