Commercial buildings contribute to 19% of the primary energy consumption in US, with HVAC systems accounting for 39.6% this usage. To reduce use, prior studies have proposed using wireless occupancy sensors or even cameras based actuation showing savings up 42%. However, most these solutions require and associated network be designed, deployed, tested maintained within existing which is significantly costly.
Optical memristive switches can be used as optical latching in which the switching state is changed only by applying an electrical Write/Erase pulse and maintained without external power supply. We demonstrate switch based on a silicon multimode interferometer structure covered with nanoscale-sized Ge2Sb2Te5 (GST) material top. The phase change of GST triggered resistive heating layer beneath pulse. Experimental results reveal that transmissivity tuned controllable repeatable manner. Partial...
Emerging fast, persistent memories will enable systems that combine conventional DRAM with large amounts of non-volatile main memory (NVMM) and provide huge increases in storage performance. Fully realizing this potential requires fundamental changes how system software manages, protects, provides access to data resides NVMM. We address these needs by describing an NVMM-optimized file called NOVA-Fortis is both fast resilient the face corruption due media errors bugs. identify propose...
Electro-optic modulators are key components in data communication, microwave photonics, and quantum photonics. Modulation bandwidth, energy efficiency, device dimension crucial metrics of modulators. Here, we provide an important direction for the miniaturization electro-optic by reporting on ultracompact topological A interface state a one-dimensional lattice is implemented thin-film lithium-niobate integrated platform. Due to strong optical confinement peaking enhancement response, cavity...
High-strength elastomers capable of room-temperature healing hold promising applications in flexible electronics. However, the unwanted spontaneous merging for incorrect contact (such as folding or stacking) during use process will prevent widespread promotion these elastomers. By simulating strengthening and processes natural skin, a series robust kinetically stable poly(urea-urethane) (PUU) were synthesized by integrating three reversible interactions, including dynamic disulfide bonds,...
To improve the mechanical performance of carbon fiber (CF)/epoxy composites in high-temperature environments, a moderately modulus gradient interlayer was constructed at interface phase region composites. This involved design "rigid-flexible" synergistic reinforcement structure, incorporating rigid nanoparticle GO@CNTs and flexible polymer polynaphthyl ether nitrile ketone onto CF surface. Notably, 180 °C, compared to commercial composites, CF-GO@CNTs-PPENK displayed remarkable improvement...
Phase change materials combined with silicon photonics are emerging as a promising platform to realize miniature photonic devices. We study the basic optical properties of subwavelength-dimension ridge waveguide 20-nm-thick Ge2Sb2Te5 (GST) top-clad layer. Numerical simulations show that effective index Si-GST hybrid varies significantly when GST changes from amorphous crystalline states. This can be utilized make micron-size To experimentally verify effectiveness on light wave manipulation,...
