    Journal of Polymer Materials, Vol.42, No.4, pp. 909-927, 2025, DOI:10.32604/jpm.2025.071607 - 26 December 2025

    Abstract MXene (Ti3C2Tx) is known for its excellent hydrophilicity, electrical conductivity, and dispersibility. It is a promising candidate for the fabrication of moisture-responsive actuators due to the strong interaction between MXene sheets and water molecules. Inspired by natural organisms, a variety of moisture-actuated soft robots have been successfully developed through the systematic integration of MXene-based actuators. This minireview summarizes recent advances in the preparation and applications of MXene-based moisture-responsive actuators. The hydrophilic properties of MXene, along with design principles, working mechanisms, current progress, and applications of MXene-based actuators, are discussed.

    Farhat Abbas1, Fahim Ullah Khan1,2,*, Salem Al-Naemi3, Awni Al-Otoom1, Ahmed T. Moustafa4, Khaled Shami1

    Phyton-International Journal of Experimental Botany, Vol.94, No.9, pp. 2911-2925, 2025, DOI:10.32604/phyton.2025.064239 - 30 September 2025

    Abstract This study aimed to explore the relationship between Soil-Plant Analysis Development (SPAD) values and key environmental factors in cucumber (Cucumis sativus L.) cultivation in a greenhouse. SPAD values, indicative of chlorophyll content, reflect plant health and productivity. The analysis revealed strong positive correlations between SPAD values and both indoor light intensity (ILI, r = 0.59, p < 0.001) and outdoor light intensity (OLI, r = 0.62, p < 0.001), suggesting that higher light intensities were associated with enhanced SPAD values. In contrast, significant negative correlations were found between SPAD values and soil temperature at 15–30 cm depth… More >

    Martin Nyanzi Mawejje, Jon Pocock, Santiago Septien*

    Energy Engineering, Vol.122, No.8, pp. 3177-3199, 2025, DOI:10.32604/ee.2025.063898 - 24 July 2025

    Abstract Onsite sanitation offers a sustainable alternative to centralized wastewater treatment; however, effective faecal sludge management is crucial for safe disposal and resource recovery. Among emerging treatment solutions, solar thermal drying holds significant promise to reduce sludge moisture content and enhance handling. Despite this potential, its application remains limited, with important knowledge gaps, particularly concerning the drying kinetics under different environmental and operational conditions. This study aims to fill these gaps by investigating the solar thermal drying behaviour of faecal sludge from ventilated improved pit latrines (VIPs) and urine-diverting dry toilets (UDs), with a specific focus… More >

    Abstract The aim of this paper was to characterize through experiment the moisture and temperature kinetic behavior of Eucalyptus gomphocephala wood samples using microwave heating (MWH) in two scenarios: intermittently and continuously. The mechanical properties and surface appearance of the heated samples were also investigated. Continuous and intermittent microwave drying kinetic experiments were conducted at a frequency of 2.45 GHz using a microwave laboratory oven at 300, 500, and 1000 watts. Drying rate curves indicated three distinct phases of MWH. Increasing the microwave power with a shorter drying time led to rapid increases in internal temperature and… More >

    Interplay between Plants and Microbial Communities: Insights from Holobionts and Environmental Interactions

    Sejin Choi1,2, Ho-Seok Lee1,2,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.10, pp. 2519-2534, 2024, DOI:10.32604/phyton.2024.058012 - 30 October 2024

    Abstract Plants interact with a complex network of microorganisms, forming a dynamic holobiont that is crucial for their health, growth, and adaptation. This interconnected system is deeply influenced by environmental factors, which modulate the relationships within the plant microbiome. Key environmental drivers such as light, temperature, and moisture can alter the balance of these interactions, impacting plant immunity, resilience, and overall fitness. The traditional disease triangle model, which emphasizes plant-pathogen-environment interactions, is enhanced by incorporating the role of the microbiome, revealing how microbial communities contribute to disease outcomes.

    CMES-Computer Modeling in Engineering & Sciences, Vol.141, No.1, pp. 107-126, 2024, DOI:10.32604/cmes.2024.053199 - 20 August 2024

    Abstract In this research, we focus on the free-surface deformation of a one-dimensional elastic semiconductor medium as a function of magnetic field and moisture diffusivity. The problem aims to analyze the interconnection between plasma and moisture diffusivity processes, as well as thermo-elastic waves. The study examines the photo-thermoelasticity transport process while considering the impact of moisture diffusivity. By employing Laplace’s transformation technique, we derive the governing equations of the photo-thermo-elastic medium. These equations include the equations for carrier density, elastic waves, moisture transport, heat conduction, and constitutive relationships.

    Long Yu, Dongdong Pang*, Minmin She, Hongwei Qiu, Ping Cao, Xiongwei You

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.8, pp. 1823-1846, 2024, DOI:10.32604/fdmp.2024.048093 - 06 August 2024

    Abstract In this study, the motion of wet particles in the drying unit of a vertical powder dryer is investigated by using a Discrete element method (DEM) coupled with a liquid bridge force. In particular, by varying parameters such as the particle mass flow rates, the superficial gas velocities, and superficial gas temperatures, the influence of the moisture content on the flow behavior is examined. The results show that when the moisture content increases, the mean particle velocity decreases while the bed mean solid “holdup” and the mean residence time (MRT) of particles grow. It is More > Graphic Abstract
