We report continuous wave lasing operation at T=260 K of subwavelength-metallic-cavities with semiconductor core encapsulated in silver under electric injection. The physical cavity volumes the two lasers presented are 0.96λ3 (λ=1563.4 nm) and 0.78λ3 (λ=1488.7 nm), respectively. Longitudinal modes observed one correspond to Fabry–Perot length direction. Such record high temperature a subwavelength laser is great importance for development small light sources future integrated photonic...
With the rapid developments of renewable energy sources, uncertainty power supply will bring new challenges to scheduling problems, and conventional strategies may lose their effectiveness. The current general need model environment, while it is difficult achieve a high degree accuracy in system with penetration rate energy, which directly affect result. In response this problem, paper studies economic dispatch systems based on deep deterministic policy gradient (DDPG),which avoids modeling...
We demonstrated for the first time an azimuthally polarized laser source from electrically driven metallic cavity nanolaser with a physical volume of 0.146 λ3 (λ = 1416 nm). Single TE01 mode lasing at 78 K was achieved by taking advantages large free spectral range in such nanoscale lasers and azimuthal polarization emission verified experimentally. Mode shift controlled device radius observed over wavelength 1.37 μm to 1.53 μm. Such provides compact beam.
A novel hydrophilic-modified gas diffusion layer (GDL) through inserting the polyacrylonitrile (PAN) into microporous is fabricated to elevate performance of proton exchange membrane fuel cells (PEMFCs) under low humidfication. The single cell test confirms that electrode assembly with 3 wt% addition PAN in cathode GDL exhibits a maximum power density 0.616 W cm−2, which 30% higher than conventional hydrophobic (0.480 cm−2) humidity. This significant enhancement attributed powerful...
Dihydro-nicotinamide adenine dinucleotide (NADH) detection is crucial since it a vital coenzyme in organism metabolism. Compared to the traditional method based on natural NADH oxidase (NOX), nanozymes with multienzyme-like activity can catalyze multistage reactions singular setup, simplifying processes and enhancing sensitivity. In this study, an innovative was developed using iron-doped carbon (Fe@C) nanozyme synthesized from metal-organic frameworks situ reduced Pt clusters. This...
Abstract In current power grids, a massive amount of equipment raises various emerging requirements, e.g., data perception, information transmission, and real-time control. The existing cloud computing paradigm is stubborn to address issues challenges such as rapid response local autonomy. Microgrids contain diverse adjustable components, making the system complex difficult optimize. traditional adjusting methods are manual centralized, which requires many human resources with expert...
Phase-change materials, also well known as the Chalcogenide alloy, have received considerable attention during last two decades owing to its widespread applications in field of electrical storage market such phase-change random access memory and probe memory. In addition devices, unique properties that can be dynamically tunable with respect excitations lead numerous novel represented by memristor memristor-based neuromorphic circuits. These emerging undoubtedly allows for a further...
In order to improve the dynamics of surface-mounted permanent magnet synchronous motors (SPMSM) used in servo systems, finite control set model predictive current (FCS-MPCC) methods have been widely adopted. However, because FCS-MPCC is a model-based strategy, its performance highly depends on machine parameters, such as winding resistance, inductance and flux linkage. Unfortunately, parameter mismatch problem common due measurement precision environmental impacts (e.g., temperature). To...
