Neuromorphic visual systems can emulate biological retinal to perceive information under different levels of illumination, making them have considerable potential for future intelligent vehicles and vision automation. However, the complex circuits high operating voltages conventional artificial present great challenges device integration power consumption. Here, bioinspired synaptic transistors based on organic single crystal phototransistors are reported, which exhibit excitation inhibition...
The detection of X-rays has always been a frontier scientific research. An Eu-MOF with both X-ray-induced photochromic and scintillation properties synthesized through the combination photochromism-active viologen ligand rare earth Eu element high-efficiency absorption X-rays. In bright environment, exhibits different color changes under high-energy low-energy X-rays, which can effectively distinguish also be used for X-ray by in dark environments. This work provides new perspective on...
The spectroscopic techniques for time-resolved fine analysis of matter require coherent X-ray radiation with femtosecond duration and high average brightness. Seeded free-electron lasers (FELs), which use the frequency up-conversion an external seed laser to improve temporal coherence, are ideal providing fully soft pulses. However, it is difficult operate seeded FELs at a repetition rate due limitations present state-of-the-art systems. Here, we report novel self-modulation method enhancing...
With the safety and reliability of electrical equipment used in information systems becoming more important, prefabricated fire-extinguishing devices using heptafluoropropane as extinguishing agent have broad application prospects. However, few studies focused on vaporization performance context fire suppression safe distance for equipment. This study proposes a numerical simulation model to analyze cooling sprayed heptafluoropropane. First, experimental measurements with no source are...
Defect free copper welds were achieved by friction stir welding (FSW) carried out at a constant speed of 100 mm min −1 . The influence tool rotation rate on microstructure, mechanical properties and fracture location was investigated. As the increased, grains nugget zone grew significantly, thermomechanically affected became indistinct grain size but effect heat limited. Both ultimate tensile strength (UTS) elongation increased first then decreased with increasing UTS highest value 282 MPa...
In this study, 5-(4-aminophenyl)-10,15,20-triphenylporphyrin]Mn(<sc>iii</sc>) (MnNH<sub>2</sub>TPP) and graphene oxide (GO) composite materials (GO–MnNH<sub>2</sub>TPP) were successfully used to modify a glassy carbon electrode (GC) by the drop casting method.
Abstract 2D emissive crystals have attracted tremendous research interests due to their outstanding compatibility with an integrated planar photonic system, which ideally meet the requirement for versatile device applications, such as lasers, light‐emitting devices, and optical waveguides. Among materials, metal‐organic complex are highly desirable because of strong charge‐transfer interactions enhanced absorption that benefit superior luminescence efficiency. Here, in‐air sublimation method...
Abstract A plasmonic sensor is proposed, comprising a metal–insulator–metal (MIM) straight waveguide and ring cavity with one stub (RCS).

It demonstrates sensing resolution SR 4.98 × 10 −7 in detection refractive index variation. Based on optimized temperature investigated...
We report the first laterally coupled hexagonal micropillar resonator add-drop filters in silicon nitride. Our experiment reveals waveguide-coupled resonances of six-bounce ray orbits microcavity. By tuning submicrometer waveguide width, we demonstrate simultaneous optimization coupling efficiency and resonance Q value. attribute optimum width to near k-vector matching between input- output-coupled fundamental mode cavity modes that are coherently along flat sidewalls.
Abstract The inexorable trend of spintronics is to develop efficient spin‐control methods. For example, photovoltaic driven by sunlight has great potential in energy‐saving applications.
