A new study led by nanotechnology and biotechnology experts at Rensselaer Polytechnic Institute is providing important details on how proteins in our bodies interact with nanomaterials. In their new study, published in the Feb. 2 online edition of the journal Nano Letters, the researchers developed a new tool to determine the orientation of proteins on different nanostructures. The discovery is a key step in the effort to control the orientation, structure, and function of proteins in the body using nanomaterials.
The relationship of post-hardening cooling to the properties of steel is widely studied and monitored. In the simplest situations, it may just be necessary to achieve rapid enough cooling to avoid the pearlite and/or bainite "noses" on the continuous cooling transformation diagram. In other cases, this may not be possible, necessary or even desirable, and attention must be focused on cooling control and engineering. Large forgings present these challenges, particularly since slow cooling may be unavoidable in the workpiece interior.
Conventional sensing techniques use chemical reactions in order to detect the presence of very specific toxicants which fails when unknown, engineered pathogens are introduced. By examining the global function of cell metabolism, instead of specific reactions, a wider range of pathogens can be detected. Much like a canary in a coal mine, mammalian cells will reaction adversely to toxicants that will endanger our own health.
Engineers at Rensselaer Polytechnic Institute and Rice University Discover How the Extreme Thinness of Graphene Enables Near-Perfect Wetting Transparency
Graphene is the thinnest material known to science. The nanomaterial is so thin, in fact, water often doesn’t even know it’s there.
