    Phyton-International Journal of Experimental Botany, Vol.95, No.1, 2026, DOI:10.32604/phyton.2026.074434 - 30 January 2026

    Abstract As its tuberous alkaloids induce valuable pharmacological effects, Pinellia ternata has considerable clinical value. However, its production currently fails to meet its demand. In vitro microtuber culture, combined with salicylic acid (SA) elicitation, may provide an effective alternative to traditional field production. In this study, an in vitro P. ternata microtuber induction system was developed and used to evaluate SA-induced elicitation of alkaloid accumulation. The quality of in vitro microtubers was assessed by total alkaloid measurement, a cytotoxicity assay, and transcriptomic analysis. With or without SA treatment, P. ternata microtuber induction was achieved within 60 d using petiole-derived explants, with… More >

    Shengkang Zhang1, Yong Jin2,*, Soon Poh Yap1,*, Haoyun Fan1, Shiyuan Li3, Ahmed El-Shafie4, Zainah Ibrahim1, Amr El-Dieb5

    CMES-Computer Modeling in Engineering & Sciences, Vol.146, No.1, 2026, DOI:10.32604/cmes.2025.075351 - 29 January 2026

    Abstract Concrete-filled steel tubes (CFST) are widely utilized in civil engineering due to their superior load-bearing capacity, ductility, and seismic resistance. However, existing design codes, such as AISC and Eurocode 4, tend to be excessively conservative as they fail to account for the composite action between the steel tube and the concrete core. To address this limitation, this study proposes a hybrid model that integrates XGBoost with the Pied Kingfisher Optimizer (PKO), a nature-inspired algorithm, to enhance the accuracy of shear strength prediction for CFST columns. Additionally, quantile regression is employed to construct prediction intervals for… More >

    Najiba Hasan Hamad1,*, Ranj Sirwan Abdullah2, Ahmed Mohammed Adham2

    Energy Engineering, Vol.123, No.1, 2026, DOI:10.32604/ee.2025.073377 - 27 December 2025

    Abstract Coiled tube heat exchangers are widely preferred in shell structures due to their superior heat transfer performance, driven by favorable flow characteristics. This study investigates the effect of modifying coil and shell configurations on heat transfer efficiency. Two key enhancements were examined: adding fins to the outer coil surface and integrating longitudinal slots within a hollowed shell. These modifications promote turbulence and extend heat transfer duration, thereby improving performance. However, they also introduce challenges, including increased pressure loss and manufacturing complexity. Numerical simulations were conducted using ANSYS Fluent 2024R1 under identical boundary conditions. With a… More > Graphic Abstract

    Enhancing Functional Stability of NiTi Tube for Elastocaloric Cooling Through Overstress Training

    Qiuhong Wang1, Hao Yin1,*, Qingping Sun1,2,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.34, No.1, pp. 1-1, 2025, DOI:10.32604/icces.2025.012656

    Abstract Tubular NiTi is a promising candidate of eco-friendly solid-state refrigerant for elastocaloric cooling, but the severe functional degradation of NiTi material during cyclic phase transition (PT) is a key concern in the technology development. Here, plastic deformation of 6.7% is applied on the NiTi tube by overstress training under 1900 MPa for five cycles to improve the cyclic PT stability without losing cooling efficiency. It is found that after 106 compressive cycles under an applied stress of 1000 MPa, the overstress-trained NiTi tube exhibits small residual strain (0.5%), stable adiabatic temperatures drop (T=11K) and improved… More >

    Ghinwa Al Mimar1, Natrah Kamaruzaman1,*, Kamil Talib Alkhateeb2

    Frontiers in Heat and Mass Transfer, Vol.23, No.6, pp. 1933-1956, 2025, DOI:10.32604/fhmt.2025.070118 - 31 December 2025

    Abstract The pivotal role microchannels play in the thermal management of electronic components has, in recent decades, prompted extensive research into methods for enhancing their heat transfer performance. Among these methods, surface wettability modification was found to be highly effective owing to its significant influence on boiling dynamics and heat transfer mechanisms. In this study, we modified surface wettability using a nanocomposite coating composed of graphene nano plate (GNPs) and multi-walled carbon nanotubes (MWCNT) and then examined how the modification affected the transfer of boiling heat in microchannels. The resultant heat transfer coefficients for hydrophilic and… More >

    Preparation of ZnS-Carbon nanotube nanocomposites via solvothermal method and their application in electrochemical detection of escherichia coli O157:H7

    F. F. Tonga,*, J. L. Hanb

    Chalcogenide Letters, Vol.22, No.8, pp. 719-733, 2025, DOI:10.15251/CL.2025.228.719

    Abstract In this study, hierarchical ZnS–CNT hybrids were synthesized via a solvothermal reaction at 180 °C for 48 h, producing ∼200 nm ZnS spheres uniformly anchored onto oxidized multiwalled carbon nanotubes. Structural analyses by XRD confirmed the cubic sphalerite phase, while SEM and TEM revealed a “pearl-necklace” morphology and effective nanoparticle dispersion. XPS spectra verified Zn2+ and oxygen-containing surface groups on the composite. Nitrogen adsorption–desorption measurements showed that incorporating CNTs transformed the material’s isotherm from type III to type IV, increasing the BET surface area from 68 to 155 m2 /g and introducing mesoporosity.

    Boudjema Bendaho1, Abdelhak Mesbah1, Zakaria Belabed1,2,*

    CMC-Computers, Materials & Continua, Vol.85, No.2, pp. 2781-2805, 2025, DOI:10.32604/cmc.2025.069709 - 23 September 2025

    Abstract A new quadrilateral finite element IQ4 is developed for the free vibration of carbon nanotube-reinforced composite (CNTRC) perforated plates with a central cutout. By enriching the membrane part and incorporating a projected shear technique, the IQ4 element is proposed to address the known limitations of the standard Q4 element, such as shear locking and limited consistency in the coupling of membrane-bending components. The proposed element is formulated within the FSDT-based framework and assessed through benchmark tests to verify its convergence and accuracy. The governing equations are obtained via the weak form of Hamilton’s principle. Particular… More >
