NMTI announces breakthrough solutions for HAMR nanoantenna for next-generation ultra-high density magnetic storage

The key problem currently faced by plasmonics is related to material limitations. After almost two decades of extreme excitement and research largely based on the use of noble metals, scientists have come to a consensus on the importance of exploring alternative plasmonic materials to address application-specific challenges to enable new functional devices. Such a change in the motivation will undoubtedly lead to significant advancements in plasmonics technology transfer and could have a revolutionary impact on nanophotonic technologies in general. Here, we report on one of the approaches that, together with other new material platforms, mark an insightful technology-driven era for plasmonics. Our study focuses on transition metal nitrides as refractory plasmonic materials that exhibit appealing optical properties in the visible and near infrared regions, along with high temperature durability. We take heat-assisted magnetic recording as a case study for plasmonic technology and show that a titanium nitride antenna satisfies the requirements for an optically efficient, durable near field transducer paving the way to the next generation data recording systems.

Researchers at Nano-Meta Technologies Inc. (NMTI) in the Purdue Research Park have shown how to overcome key limitations of a material that could enable the magnetic storage industry to achieve data-recording densities far beyond today's computers.

Biosenta Inc. Updates New Household Disinfectant Testing Results; It Kills 100% of a Broad Range of Deadly Molds, Fungi, Bacteria, and Viruses, Including Ebola and Enterovirus D68

Biosenta's new disinfectant has been proven in laboratory tests to be effective in killing 100% of potentially deadly molds and fungi, and a wide range of bacteria and viruses, on hard surfaces. According to U.S. Center for Disease Control (CDC) reports, new disinfectant will kill Ebola and Enterovirus D68. This is based on laboratory tests that prove new disinfectant kills the Polio virus which is very similar in cell structure to Ebola and Enterovirus D68.

Spiraling light, nanoparticles and insights into life’s structure

As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented sugars ever make into life as we know it.

New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these quasars tend to be aligned with the vast structures in the cosmic web in which they reside.
