Ultralight (<10 milligrams per cubic centimeter) cellular materials are desirable for thermal insulation; battery electrodes; catalyst supports; and acoustic, vibration, or shock energy damping. We present ultralight based on periodic hollow-tube microlattices. These fabricated by starting with a template formed self-propagating photopolymer waveguide prototyping, coating the electroless nickel plating, subsequently etching away template. The resulting metallic microlattices exhibit...
Emerging capability to fabricate well-defined, ordered lattice structures offers opportunity create new energy absorption materials with previously unachieved properties. Metallic microlattices can be designed maximize while not transmitting a stress greater than the injury or damage threshold. The stress–strain response of different microlattice is characterized under quasi-static and dynamic loading compared state-of-the-art materials.
Single crystalline 4H-SiC is a wide-gap semiconductor with optical properties that are poised to enable new applications in MEMS and quantum devices. A number of key hurdles remain respect the micro nano-fabrication SiC prepare precise photonic structures nanometer-scale precision. These challenges include development fast, scalable etching process for capable producing sub-nanometer roughness surface while simultaneously reducing total thickness variation across wafer. Our investigation...
Abstract A deployment-scale array of locally resonant membrane-type acoustic metamaterials (MAMs) is fabricated. The performance the measured in a transmission loss chamber, and complex interaction between individual cell length scales shown to exist. Transmission behavior both membrane are independently studied using analytical models, method for estimating through structure that combines vibroacoustic predictions from presented agree with measurements. Degradation often associated scaling...
Abstract Flexibility and cost effectiveness became priorities for semiconductor giant Intel when it sought employee child care options in the midst of its worst business downturn. An innovative solution leverages community resources at sites around country to offer locally managed home‐based programs as an alternative center‐based care. In process, new program has improved quality at‐home care, created more spaces, given providers access clients resources, benefit a whole. © 2005 Wiley...
