Heating consumes large amount of energy and is a primary source greenhouse gas emission. Although energy-efficient buildings are developing quickly based on improving insulation design, portion continues to be wasted heating empty space nonhuman objects. Here, we demonstrate system personal thermal management using metallic nanowire-embedded cloth that can reduce this waste. The nanowires form conductive network not only highly insulating because it reflects human body infrared radiation but...
Two-dimensional layered materials like MoS2 have shown promise for nanoelectronics and energy storage, both as monolayers bulk van der Waals crystals with tunable properties. Here we present a platform to tune the physical chemical properties of nanoscale by electrochemically inserting foreign species (Li+ ions) into their interlayer spacing. We discover substantial enhancement light transmission (up 90% in 4 nm thick lithiated MoS2) electrical conductivity (more than 200×) ultrathin (∼2–50...
Abstract Enhancing and spectrally controlling light absorption is of great practical fundamental importance. In optoelectronic devices consisting layered semiconductors metals, has traditionally been manipulated with the help Fabry-Pérot resonances. Even further control over spectral properties thin films achieved by patterning them into dense arrays subwavelength resonant structures to form metafilms. As next logical step, we demonstrate electrical in metafilms constructed from actively...
Water pollution is an increasingly serious environmental problem because many pollutants have carcinogenic effects on humans and aquatic organisms. Metal organic framework (MOF) made up of metal ions multifunctional ligands has been one the most concerned materials its adjustable regular pore structure. MOFs always shown attractive advantages in membrane separation adsorption technologies, among which water-stable are particularly prominent wastewater treatment (WWT) applications. This...
Accumulating electrons in transparent conductive oxides such as indium tin oxide (ITO) can induce an "epsilon-near-zero" (ENZ) the spectral region near important telecommunications wavelength of λ = 1.55 μm. Here we theoretically demonstrate highly effective optical electro-absorptive modulation a silicon waveguide overcoated with ITO. This modulator leverages combination local electric field enhancement and increased absorption ITO when this material is locally brought into ENZ state via...
Thermal emission from objects tends to be spectrally broadband, unpolarized, and temporally invariant. These common notions are now challenged with the emergence of new nanophotonic structures concepts that afford on-demand, active manipulation thermal process. This opens a myriad applications in chemistry, health care, management, imaging, sensing, spectroscopy. Here, we theoretically propose experimentally demonstrate approach actively tailor reflective, plasmonic metasurface which...

Offset maps show that sequence ruptured ∼300 km along East Anatolian Fault (EAF) ∼180 secondary Cardak Dogansehir faults. infer slip distribution interseismic fault motion by inverting co‐ inter‐seismic observations. Inversion results (∼8.0 m) strike‐slip rate (∼4.6 mm/yr) on main rupture event are basically consistent with ∼8.4...
Doped indium tin oxide (ITO) behaves as a Drude metal with plasma frequency that is controlled by its free carrier density. In this work, we systematically tune across the mid-infrared range annealing treatments in reducing environment produce high electron concentrations (∼1021 cm−3). The changes ITO's optical properties result from density are measured attenuated total reflection measurements. These measurements complemented Hall to obtain comprehensive picture of response ITO films. It...
We experimentally demonstrate a broadband electro-absorption modulator exploiting indium tin oxide (ITO) as the active switching material. Si strip waveguides are fabricated and covered with 8 nm of HfO2 15 ITO to form metal-oxide-semiconductor capacitor (MOS-C) based modulators. The mobile carrier density in film is controlled using postanneal treatment tune its permittivity ε near-zero value at operation wavelength 1550 nm. Using simulations experiments, we that realizing an...
Metal-organic frameworks (MOFs), a novel type of porous crystalline material, have aroused widespread interest in lithium-ion batteries (LIBs). The design and preparation MOF electrodes with stable structure excellent electrochemical performance are primary concerns for improving the capacity LIBs. Among them, two-dimensional (2D) materials larger specific surface areas, richer active sites, higher aspect ratios great potential. We adopted facile approach to synthesize unique Co-MOF...
Abstract Variability quenching is a widespread neural phenomenon in which trial‐to‐trial variability (TTV) of activity reduced by repeated presentations sensory stimulus. However, its mechanism and functional significance remain poorly understood. Recurrent network dynamics are suggested as candidate TTV, they play key role consciousness. We thus asked whether the variability‐quenching related to level hypothesized that TTV reduction would be compromised during consciousness propofol...
A metal naturally displays dramatic changes in its optical properties near the plasma frequency where permittivity from a negative to positive value, and material turns highly reflective transparent. For many applications, it is desirable achieve such large by electrical gating. However, this challenging given high carrier density of most metals, which causes them effectively screen externally applied fields. Indium tin oxide (ITO) low-electron-density that does afford electric tuning...
Abstract Interferometric synthetic aperture radar (InSAR) has become an important technique for studying earthquake cycle deformation. However, due to the limited satellite revisit time, it is often difficult fully separate coseismic and postseismic slip from InSAR data. Nevertheless, accurately estimating spatiotemporal fault distribution models quantifying slip, understanding kinematics of seismogenic faulting, evaluating seismic hazards. Here, we develop a logarithmic model‐based method...
We have measured the electron affinities of clean, stoichiometric InN and GaN polar surfaces via ultraviolet photoelectron spectroscopy. The were to be 4.7 4.6 eV for In- N-polar surfaces, respectively. In contrast, vary greatly with film polarity, i.e., 3.8 3.3 Ga- propose that difference between originates from spontaneous polarization effect. Furthermore, it's closely related carrier concentration. With affinities, we are able confirm known heterojunction band alignments.
