    Abstract: A facile synthesis method for the heterostructures of single‐walled carbon nanotubes (SWCNTs) and few‐layer MoS 2 is reported. The heterostructures are realized by in situ chemical vapor deposition of MoS 2 on individual SWCNTs. Field effect transistors based on the heterostructures display different transfer characteristics depending on the formation of MoS 2 conduction channels along SWCNTs. Under light illumination, negative photoresponse originating from charge transfer from MoS 2 to SWCNT is observed while positive photoresponse is observed in MoS 2 conduction channels, leading to ambipolar photoresponse in devices with both SWCNT and MoS 2 channels. The heterostructure phototransistor, for negative photoresponse, exhibits high responsivity (100–1000 AW −1 ) at low bias voltages (0.1 V) in the visible spectrum (500–700 nm) by combining high mobility conduction channel (SWCNT) with efficient light absorber (MoS 2 ).

    Synthesis of Nb‐Doped‐WS 2 –NbS 2 : A Degenerate‐Semiconductor–Metal Heterostructure
    Wiley ; 2024
    In:  Advanced Electronic Materials
    Details
    In: Advanced Electronic Materials, Wiley
    Abstract: The synthesis of semiconductor–metal (S–M) heterostructures comprising semiconducting (S)‐transition metal dichalcogenides (TMDs) and metallic (M)‐TMDs via chemical vapor deposition (CVD) has emerged as a highly promising avenue for achieving low contact resistance in TMD‐based devices. However, CVD‐grown S–M heterostructures are mainly focused on non‐degenerate semiconductors, despite degenerate semiconductors also being essential for semiconductor technology, such as negative differential resistance (NDR) device. In this study, a degenerate‐S–M heterostructure, Nb‐doped‐WS 2 –NbS 2 , is synthesized via CVD with a liquid‐metal precursor. Optimizing the growth parameters, such as growth temperature, precursor ratio, and H 2 content in the mixture gas, affords the desirable degenerate‐Nb‐doped‐WS 2 –NbS 2 heterostructure. Raman and photoluminescence spectroscopies, transmission electron microscopy, and energy‐dispersive spectroscopy clearly clarify the doping signal and layer structure of the heterostructure. A growth mechanism has been proposed using in‐plane and vertical models based on structural analysis. Electrical transport measurements reveal degenerate p‐type behavior in the Nb‐doped‐WS 2 . In the Nb‐doped‐WS 2 –NbS 2 degenerate‐S–M heterostructure, the device flows about twice as much on‐state current as that by an Nb‐doped‐WS 2 /Cr contact.

    Synthesis of NbSe 2 /Bilayer Nb‐Doped WSe 2 Heterostructure from Exfoliated WSe 2 Flakes

    Abstract: Forming heterostructures of 2D metals and semiconductors using chemical vapor deposition (CVD) has significant potential to effectively reduce contact resistance in electronic devices. However, semiconducting transition metal dichalcogenide (TMD) layers in metal–semiconductor heterostructures are currently restricted to monolayers despite the superior mobility and density of states in bilayer TMDs. Herein, NbSe 2 /bilayer Nb‐doped WSe 2 metal/semiconductor heterostructure from exfoliated WSe 2 flakes are synthesized first. The exfoliated WSe 2 bulk crystals on an Nb‐coated substrate are heated to 950 °C under a flow of selenium vapor, and then the NbSe 2 /bilayer Nb‐doped WSe 2 heterostructures are formed. Statistics on the number of Nb‐doped WSe 2 layers grown on a 1 cm × 1 cm CVD substrate shows that 65% of the Nb‐doped WSe 2 layers are grown as bilayers. X‐ray photoelectron spectroscopy, optical microscopy, and transmission electron microscopy clearly clarify the number of Nb‐doped WSe 2 layers and heterostructure of NbSe 2 /bilayer Nb‐doped WSe 2 . Electrical measurements using Cr contacts show that bilayer Nb‐doped WSe 2 displays 7‐ and 10‐times higher mobility and on/off ratio than monolayer Nb‐doped WSe 2 . The mobility and on/off ratio are further doubled in NbSe 2 /bilayer Nb‐doped WSe 2 contact compared to Cr/bilayer Nb‐doped WSe 2 contact, attributed to a clean interface in vertical stack heterostructure, enhancing electrical performance.

    A free surface flow solver for complex three‐dimensional water impact problems based on the VOF method
    Wiley ; 2016

    In: International Journal for Numerical Methods in Fluids, Wiley, Vol. 82, No. 1 ( 2016-09-10), p. 3-34
    Abstract: A three‐dimensional numerical model is developed to analyze free surface flows and water impact problems. The flow of an incompressible viscous fluid is solved using the unsteady Navier–Stokes equations. Pseudo‐time derivatives are introduced into the equations to improve computational efficiency. The interface between the two phases is tracked using a volume‐of‐fluid interface tracking algorithm developed in a generalized curvilinear coordinate system. The accuracy of the volume‐of‐fluid method is first evaluated by the multiple numerical benchmark tests, including two‐dimensional and three‐dimensional deformation cases on curvilinear grids. The performance and capability of the numerical model for water impact problems are demonstrated by simulations of water entries of the free‐falling hemisphere and cone, based on comparisons of water impact loadings, velocities, and penetrations of the body with experimental data. For further validation, computations of the dam‐break flows are presented, based on an analysis of the wave front propagation, water level, and the dynamic pressure impact of the waves on the downstream walls, on a specific container, and on a tall structure. Extensive comparisons between the obtained solutions, the experimental data, and the results of other numerical simulations in the literature are presented and show a good agreement.

    Abstract: In the modern era of software‐defined networking (SDN), network monitoring is becoming more important for providing information about a network and helping SDN controllers to make decisions about the network. In‐band Network Telemetry (INT) is a new network monitoring framework that collects packet‐level network information to provide real‐time and fine‐grained network monitoring. In this paper, we present the design of the overall INT management architecture and its two main components: the INT management system and INTCollector. The INT management system controls heterogeneous INT‐capable devices through a common interface. INTCollector is a high‐performance collector for INT data, which uses eXpress Data Path and an event detection mechanism. The evaluation result shows that INTCollector processes telemetry reports 27 times faster than other packet‐level telemetry collectors. We made the implementation as open source, to make researchers who are interested in INT implement their own ideas on top of our work.

    Abstract: The increasing penetration of renewable energy sources, featured by intermittent outputs, emphasizes the investigation of the potential effects on frequency deviation in the normal operation and solving the associated problems. This paper proposes a method for assessing the impacts of forecast errors in wind and solar generation outputs on a unit commitment problem. An iterative process is used across different spinning reserve requirements until the hourly average and intrahour variation forecast errors in demand and renewable energy generation are fully compensated at the lowest cost. The process, containing time series simulations, is applied to various confidence levels of the forecasted renewable energy generation so that violations of the frequency limit will not occur in the normal operation. The effectiveness and applicability of the proposed method are well illustrated through a case study on the 2030 power system of the island of Hokkaido in Japan. © 2019 Institute of Electrical Engineers of Japan.

    Abstract: The agarophyte family Gelidiellaceae currently includes 26 species in two genera, Gelidiella and Parviphycus , but the generic status and species boundaries have not been fully explored. In order to resolve taxonomic issues in the family, we analyzed mitochondria‐encoded cox1 and plastid‐encoded rbcL and psaA genes from types and fresh collections including topotype material. The Gelidiellaceae was resolved with five distinct groups, interpreted here as representing five genera: (1) Gelidiella , including the type, (2) Huismaniella gen. nov., (3) Millerella gen. nov., (4) Parviphycus s.str. including the type, and (5) Perronella gen. nov. Gelidiella was recognized as including a new species, G. flabella , that is described for specimens from Madagascar. A new genus, Huismaniella , is described for the species previously known as Gelidiella ramellosa , characterized by lateral tetrasporangial branchlets inserted at right angles on erect axes and irregularly arranged tetrasporangia. Parviphycus includes P. adnatus which is characterized by simple thalli with tetrasporangial branchlets formed directly on prostate axes and holdfasts forming continuous fringes along the entire length of prostrate axes. The new genus Millerella is described to accommodate five species previously known as Gelidiella or Parviphycus , characterized by tetrasporangial sori formed on erect axes or branches and unicellular rhizoids forming irregular clumps along prostrate axes. Perronella gracilis gen. et sp. nov. is described for plants with terete axes, multifarious branching, and monosporangia formed on erect axes and branches. The implications for nomenclature, taxonomic revisions, and biogeography in the Gelidiellaceae are discussed.

    Contrasting patterns of genetic structure and phylogeography in the marine agarophytes Gelidiophycus divaricatus and G . freshwateri (Gelidiales, Rhodophyta) from East Asia

    Abstract: The evolutionary and population demographic history of marine red algae in East Asia is poorly understood. Here, we reconstructed the phylogeographies of two upper intertidal species endemic to East Asia, Gelidiophycus divaricatus and G . freshwateri . Phylogenetic and phylogeographic inferences of 393 mitochondrial cox 1, 128 plastid rbc L, and 342 nuclear ITS 2 sequences were complemented with ecological niche models. Gelidiophycus divaricatus , a southern species adapted to warm water, is characterized by a high genetic diversity and a strong geographical population structure, characteristic of stable population sizes and sudden reduction to recent expansion. In contrast, G . freshwateri , a northern species adapted to cold temperate conditions, is genetically relatively homogeneous with a shallow population structure resulting from steady population growth and recent equilibrium. The overlap zone of the two species roughly matches summer and winter isotherms, indicating that surface seawater temperature is a key feature influencing species range. Unidirectional genetic introgression was detected at two sites on Jeju Island where G . divaricatus was rare while G . freshwateri was common, suggesting the occurrence of asymmetric natural hybrids, a rarely reported event for rhodophytes. Our results illustrate that Quaternary climate oscillations have left strong imprints on the current day genetic structure and highlight the importance of seawater temperature and sea level change in driving speciation in upper intertidal seaweed species.

    Facile Synthesis of ZnO/Ag Nanostructure with Enhanced Photocatalytic Activity

    Abstract: A series of x%Ag/ZnO (x: 0; 1; 2; 5; 10) nanostructures were successfully synthesized through the facile method. The material's structures were confirmed through X‐ray diffraction, while their morphology, elemental distribution, and components were analyzed using cross‐sectional transmission electron microscopy (XTEM), Field‐emission scanning electron microscopy (FESEM). The optical properties of Ag/ZnO revealed a decrease in band gap from 3.2 eV to 2.83 eV and a significant reduction in photoluminescence intensity with increasing Ag nanoparticle loading on the surface of ZnO. The photocatalytic activity of synthesized Ag/ZnO flower‐like nanostructure was evaluated in the photodegradation of methylene blue (MB) under UV‐Vis irradiation. The photocatalytic results indicated that decorating Ag nanoparticles on the surface of ZnO improved the photodegradation of MB. Interestingly, the 5%Ag/ZnO showed the highest effectiveness, achieving a 99% removal efficiency of MB for 60 minutes under UV‐Vis irradiation. Notably, the ultra performance liquid chromatography‐ tandem mass spectroscopy (UPLC‐MS/MS) confirmed the structure of intermediates, while total organic carbon (TOC) removal was 47%. Moreover, the proposed mechanism for the charge transfer process was based on the results of radical scavenging experiments, which showed that superoxide was the dominant reactive species. Finally, the 5%Ag/ZnO was stable and reused at least five times.
