The scientific interest in magnetic nanostructures, both from a fundamental viewpoint and also due to their potential in a wide range of applications, over the past few years has led researchers to develop various nanofabrication methods for synthesizing nanomagnets. Applications for nanomagnetic materials include non-volatile magnetic random access memory (MRAM), highly sensitive magnetic field sensor, field programmable spin logic, and patterned media for ultra high density data storage.
A newly developed electrostatic force directed assembly (ESFDA) technique is used to efficiently coat carbon nanotubes (CNTs) with nanoparticles. This new method advances the current technology by enabling rapid and in-situ coating of CNTs, multicomponent hybrid nanostructures, more control over the assembly process, and the possibility of tuning properties of the resulted hybrid structures.
NanoFermentation is the first system to use industrial bioprocessing methods to manufacture nanometer-scale inorganic engineering materials rather than organic compounds. NanoFermentation harnesses the natural metabolic processes of metal-reducing bacteria to create tailored, single-crystal nanoparticles of important engineering materials, particularly ferrites.
Nanosprings, which are helical nanowires grown via a modified vapor-liquid-solid (VLS) mechanism, are of interest to researchers because of their potential applications in biological and chemical sensors, high porosity applications such as fuel cells, and biomedical drug delivery applications. Thanks to a novel fabrication method, nanosprings can now be synthesized with a yield higher than 90%, and with 100% repeatability.
New research shows that soft, conformable sub-wavelength phase masks can be used, with 2-photon effects, to pattern in a parallel fashion and in a single exposure step large, 3D structures in certain classes of photopolymers. The result is a technique that is simple from an experimental standpoint, but which fully exploits the flexibility and patterning capabilities enabled by 2-photon effects, making it useful for applications in photonics, microfluidics and biotechnology.
Tightly focused femtosecond laser pulses have been used to modify transparent dielectric materials, to form voids, and to polymerize resists and resins for more than a decade. A high sub-100-nm spatial resolution has now been reached making it potentially a nano-fabrication tool.
Researchers at the University of New Mexico have demonstrated a new, simple, and facile approach to the fabrication of various nanopatterned films composed of nanoparticles. The findings could lead to nanoparticle sensors for both biological and chemical species.
Contouring measurement methods are important for high quality, high speed and productivity machining in order to achieve the high precision required. Among the most commonly used methods, no measuring techniques have been available with nanometer resolution except for the grating encoder measurement system.
