Hybrid Amyloid–Boron Nitride Aerogels for Lightweight Sound Insulation

Advanced Materials, EarlyView.
Amyloid fibrils template the mild formation of boron nitride–rich hybrid aerogels with hierarchical porosity, enhanced BN‐like ordering, and fibril‐reinforced mechanics. These ultralight materials combine thermal stability with strong sound absorption and transmission loss, offering a sustainable bio‐assisted route toward lightweight acoustic shields ...

Millimeter-wave ICs

2009 IEEE Custom Integrated Circuits Conference, 2009
The rapid increase in the FTs of CMOS devices is starting to show the promise of designing millimeter-wave and even terahertz RF circuits in standard CMOS technologies. What was once the domain of exotic three-five compounds is slowing being supplanted and superseded by silicon technologies. In this millimeter-wave IC session five papers that introduce

Diplexing Millimeter Waves

International Journal of Infrared and Millimeter Waves, 1998
The paper describes a band-splitting filter or diplexer, which splits the incoming spectrum into the sub-bands 120-139 GHz and 141-158 GHz. This diplexer is intended to separate the electron cyclotron emission of a magnetically confined plasma into two subbands and to feed two independent heterodyne radiometers.
