Recently, much attention has been focused on beams carrying orbital angular momentum (OAM) for radio communication. Here we experimentally demonstrate a planar-spiral phase plate (planar-SPP) generating arbitrary mixed OAM beams. This proposed planar-SPP uses the concept of transmit array antenna having perforated substrate to control outputting with modes. As demonstrations, three planar-SPPs single mode and two modes around 94 GHz have investigated design experiments in this paper,...
Employing seawater splitting systems to generate hydrogen can be economically advantageous but still remains challenging, particularly for designing efficient and high Cl- -corrosion resistant trifunctional catalysts toward the oxygen reduction reaction (ORR), evolution (OER), (HER). Herein, single CoNC with well-defined symmetric CoN4 sites are selected as atomic platforms electronic structure tailoring. Density function theory reveals that P-doping into lead formation of asymmetric...
We introduce the atomistic observation and high-temperature shock to trigger Li–Fe reordering in LiFePO 4 , which offers a precise efficient pathway for direct recycling regeneration, along with significant techno-economic benefits.
With the continuous development of intelligent technologies, knowledge graph, backbone artificial intelligence, has attracted much attention from both academic and industrial communities due to its powerful capability representation reasoning. In recent years, graph been widely applied in different kinds applications, such as semantic search, question answering, management so on. Techniques for building Chinese graphs are also developing rapidly have constructed support various applications....
In response to the chattering issue inherent in sliding mode observers during rotor position estimation and enhance stability robustness of sensorless control systems for surface-mounted permanent magnet synchronous motors (SPMSM), this study proposes a algorithm SPMSM based on an improved super-twisting observer (ISTSMO) second-order generalized integrator (SOGI) structure. Firstly, is introduced design observer, which effectively attenuates by using continuous signals. Secondly, SOGI...
Currently, nucleic acid and antibody tests for infectious diseases are conducted independently, often resulting in fragmented diagnostics delayed clinical decision-making. Given the diversity of analytes involved diseases, comprehensive detection is essential practice. Here, we introduce One-potNASH, a novel DNA hybrid plasmonic nanoplatform that unifies within single assay. By integrating extraction-free thermal lysis 1 μL serum, One-potNASH achieves single-DNA copy sensitivity while...
Accurately diagnosing infectious diseases in a resource-limited setting is major challenge. Plasmonic materials, via localized surface plasmon resonance (LSPR), have greatly enhanced fluorescence signal and detection sensitivity. However, traditional plasmonic-enhanced methods largely rely on near-infrared or visible-light fluorophores with small Stokes shift, limiting naked-eye visibility without filters. In this study, we developed novel plasmonic silver film (pSilverF) to enhance large...
A portable and high-resolution optomechanical accelerometer employing a deformable grating-based micro-electro-mechanical system (MEMS) interferometer is presented in this Letter. The movable reflective mirror of realized by low-frequency vertical sensing structure with three-dimensional (3D)-spring construction, which, to the best our knowledge, first proposed fabricated work. All components sensor are packaged metal case compact size 4 cm×6 cm×3.15 cm. micrometer-scale springs permit...
We fabricate a miniature ultra-sensitive refractive index sensor based on tapered photonic crystal fiber (PCF) modal interferometer. The PCF is slightly and little elongated to keep the size compact. total length ~ 2 cm, potential sensitivity more than 1600 nm/RIU (refractive unit), which nearly eight times as high that of an untapered
Bone is a composite material consisting of mineral and hydrated collagen fractions. MRI bone challenging because extremely short transverse relaxation times, but solid‐state imaging sequences exist that can acquire the short‐lived signal from tissue. Previous work to quantify density via used powerful experimental scanners. This seeks establish feasibility MRI‐based measurement on clinical scanners collagen‐bound water densities, latter as surrogate matrix density, examine associations these...
A copper-catalyzed cascade coupling and aerobic oxidation of aromatic nitriles 2-aminobenzylamine for the synthesis 3,4-dihydroquinazolines quinazolineshas been achieved. The catalytic system, characterized by not adding additives using molecular oxygen as sole oxidant, exhibited exquisite substrate specificity operated under mild conditions through inherently "green" processes.
To self-sustain the constant current (CC) output to voltage (CV) transition for inductive power transfer (IPT) chargers, clamp coil-assisted IPT battery chargers are better than existing solutions due merits of no additional switching components, sensors, and control circuits. However, coil these is bulky hard design, as mutual inductances between main coupler coils significant performances. facilitate small in transmitter, this article proposes a family with proper second-order compensation...
Emerging dual-graphite batteries (DGBs) capture extensive interest for their high output voltage and exceptional cost-effectiveness. Yet, developing electrolytes compatible with both the cathode anode stands to be a tremendous challenge, how electrolyte impacts anion cation intercalation into graphite remains inexplicit or controversial. Herein, we have evaluated performance of in typical ethyl methyl carbonate (EMC) based unveiled electrode–electrolyte interphase using Cryogenic...
