Aerosol ignition in iron powder flames stabilized on a new type of jet-in-hot-coflow burner

A novel Jet-in-Hot-Coflow burner for the combustion of solid metallic particles is presented. This system features an electrically preheated coflow to ignite particles without the need for a pilot flame, mimicking exhaust gas recirculation, a method often used in industry to suppress NOx emissions and stabilize or control a combustion process. Two different iron powder samples with different particle size distributions were combusted, and their combustion products were analyzed using quantitative XRD to study the effect of particle size and interparticle heating on the ignition temperature of a suspension. It was found that a large fraction of the larger particles failed to ignite, probably due to insufficient heating during the residence time in the hot coflow. An increase in the dust concentration, expected to increase local temperatures and interparticle heating effects, did not significantly decrease the suspension ignition temperature for these powders.

Electro-Osmotic Mechanism of Ellis Fluid With Joule Heating, Viscous Dissipation, and Magnetic Field Effects in a Pumping Microtube.

The dynamics of electro-osmotically generated flow of biological viscoelastic fluid in a cylindrical geometry are investigated in this paper. This flux is the result of walls contracting and relaxing sinusoidally in a magnetic environment. The blood's viscoelasticity and shear-thinning viscosity are the primary causes of its non-Newtonian characteristics. Hence, the rheology of the fluid (blood) is accurately captured with the Ellis fluid model. Both Joule heating and viscous dissipation are accounted for during thermal analysis. The electric potential induced in the electric double layer (EDL) is obtained by applying the Debye-Huckel linearization to the nonlinear Poisson-Boltzmann equation. Mathematical modelling is incorporated in cylindrical coordinates in wave frame of reference. Assuming a long wavelength and creeping flow characterized by a low Reynolds number, the Ellis fluid model's governing equations are simplified. The resulting differential equations are evaluated numerically via the built-in tool NDSolve of the Mathematica. Graphical representations are utilized to visually and comprehensively assess the thermal characteristics, flow features, heat transfer coefficient, and skin friction coefficient. Various factors are taken into consideration, including the impact of Ellis fluid parameters, electric double layer, magnetic field, Brinkman number, and Ohmic dissipation. Ellis fluid's axial velocity boosts with a rise of the electro-osmotic parameter and power-law index while decreasing with an increase in the Hartmann number and material fluid parameter. The fluid temperature is directly proportional to EDL parameter and parameters of Ohmic and viscous dissipation. The presence of both electric and magnetic fields may aid in the management and control of Ellis fluid (blood) mobility at different temperatures, which is helpful in controlling bleeding during surgeries. The current model may be used in clinical scenarios involving the gastrointestinal system and capillaries, electrohydrodynamic therapy, delivery of drugs in pharmacological, and biomedical devices. This research creates a theoretical model that can predict the effects of different parameters on the characteristics of fluid flows that are like blood.

Tobacco production under global climate change: combined effects of heat and drought stress and coping strategies

With the intensification of global climate change, high-temperature and drought stress have emerged as critical environmental stressors affecting tobacco plants’ growth, development, and yield. This study provides a comprehensive review of tobacco’s physiological and biochemical responses to optimal temperature conditions and limited irrigation across various growth stages. It assesses the effects of these conditions on yield and quality, along with the synergistic interactions and molecular mechanisms associated with these stressors. High-temperature and drought stress induces alterations in both enzymatic and non-enzymatic antioxidant activities, lead to the accumulation of reactive oxygen species (ROS), and promote lipid peroxidation, all of which adversely impact physiological processes such as photosynthetic gas exchange, respiration, and nitrogen metabolism, ultimately resulting in reduced biomass, productivity, and quality. The interaction of these stressors activates novel plant defense mechanisms, contributing to exacerbated synergistic damage. Optimal temperature conditions enhance the activation of heat shock proteins (HSPs) and antioxidant-related genes at the molecular level. At the same time, water stress triggers the expression of genes regulated by both abscisic acid-dependent and independent signaling pathways. This review also discusses contemporary agricultural management strategies, applications of genetic engineering, and biotechnological and molecular breeding methods designed to mitigate adverse agroclimatic responses, focusing on enhancing tobacco production under heat and drought stress conditions.

Application of Triple Glazing Thickness Optimization Based on Artificial Fish Swarm Algorithm

In response to the growing demand for energy-efficient building designs in cold northern regions, this study explores the optimization of triple glazing thickness to maximize the transmission of solar energy within the wavelength range of 300-2000 nm. The optimization employs the Artificial Fish Swarm Algorithm (AFSA), which is used to iteratively determine the optimal combination of glass thicknesses. A transmittance model of solar radiation through triple glazing is established, where the thicknesses of the three glass layers are treated as variables. The study shows that the optimized thickness combination significantly enhances the indoor heating effect by maximizing solar energy incidence, offering theoretical support and practical guidance for energy-saving building designs in cold climates. Parameter settings of the AFSA, including perception range, step size, and crowding factor, are analyzed to understand their influence on optimization performance. The results suggest that AFSA efficiently addresses complex optimization problems, demonstrating its potential in optimizing material properties for energy-efficient applications. Future directions include multi-objective optimization considering additional factors such as thermal insulation and cost, algorithmic improvements to enhance search accuracy, and experimental validation of the results in real-world conditions. This research provides a scientific foundation for integrating advanced optimization algorithms into the sustainable design of building materials.

Influence of insulating and conducting walls on magnetohydodynamic flow in a suddenly expanded channel: A numerical study

ABSTRACT In this study, we conducted numerical simulations using the robust code AnuPravaha. The code’s performance was rigorously validated by benchmarking it against a range of standard cases, including Shercliff and Hunt’s cases. The same AnuPravaha code is used to identify the effect of conduction and insulating walls on a suddenly expanded channel for low Hartmann number ranging from 10–100 and Reynolds number ranging from 100–500. The results finding indicate that at a low Hartmann number Ha ≤ 40, the effect on the flow profile remains negligible. As the Hartmann number increases Ha > 40, it generates a more crescent-shaped profile, reducing the centerline flow velocity and increasing it near the side walls. It is also observed that variations in pressure drop are minimal within the low Hartmann number range of Ha = 10–30 but become very significant for a higher Hartmann number (Ha > 30). For a change in Hartmann number from Ha = 20 to Ha = 40, the pressure drop rises by 212% and at Hartmann number from Ha = 50 to Ha = 100, it increases by 284% indicating an amplification effect on the magnetic field at a higher Hartmann number. The pressure drop achieved in Insulating walls is far lesser than the conduction walls as insulating walls don’t allow any current-wall interaction. It is found that by using insulating walls the average pressure drop is reduced by about 94%. At a fixed Reynolds number, insulating walls yield higher outlet velocities than conduction walls due to lower Lorentz force resistance which modifies the volumetric heating effects. Increasing Hartmann number reduces the velocity difference between both types of walls.

Experimental study of the compact brazed heat exchanger on the thermal-hydraulic performance

ABSTRACT In this article, the heat transfer and pressure drop characteristics of a compact brazed heat exchanger (CBHE) are experimentally investigated. With the data obtained from the experiments, analyses were carried out to evaluate heat transfer, effectiveness, and pressure drop performance. From the results, it was seen that as the mass fluid rate increases, the heat transfer rate also increases. The highest heat transfer rate is 18,087 W for a mass flow rate of 210 g/s. This value is for Reynolds number 2125.72. The highest average heat transfer coefficient value in the experiments is 2106 W/m2K. In the experiments, it was seen that the efficiency values increased as the Reynolds number increased. The highest effectiveness value is 0.49. As the Reynolds number increased, the pressure drop also increased. The highest pressure loss value was found to be 20,377 Pa. Based on the results obtained from the experiments, linear correlation analysis was also performed to determine whether there is a trend between pressure drop and Re and heat transfer rate and mass flow rate. The correlation coefficient between pressure drop and Re and heat transfer rate and mass flow rate are 0.993217 and 0.979179, respectively.

Analgesic and anti-inflammatory potential of Verbesina encelioides in rodents

Background: Verbesina encelioides, a plant with a rich history in traditional medicine, is the focus of our novel research. Commonly known as golden crownbeard or cowpen daisy, this plant has been used in various cultures for its medicinal properties. However, despite its widespread use, scientific validation of its therapeutic potential, particularly its analgesic and anti-inflammatory effects, remains limited. Objectives: Our study is designed to comprehensively evaluate the analgesic and anti-inflammatory effects of methanol extracts from various parts (leaves, stems, flowers, and roots) of Verbesina encelioides. We aim to achieve this by using established animal models. Our objectives include assessing pain-relieving properties through the Hot Plate and Tail Flick tests, investigating anti-inflammatory effects via the carrageenan-induced paw edema model, and determining safe dosage ranges through acute toxicity assays. Furthermore, our goals are to validate traditional medicinal uses, assess the effectiveness of various plant sections, and find probable bioactive chemicals that could be responsible for the observed pharmacological actions. This will provide Verbesina encelioides's medicinal use with a strong scientific foundation. Techniques: The study was carried out with great care and attention to detail. Methanol was used to collect, identify, and extract Verbesina encelioides. Acute toxicity, analgesic effects (heat plate and tail flick tests), and anti-inflammatory activity (carrageenan-induced inflammation) were tested in Swiss albino mice and Wistar albino rats. Findings: The acute toxicity assay showed no adverse effects in mice up to 1000 mg/kg, a highly encouraging result. In analgesic studies, Verbesina encelioides extracts showed dose-dependent increases in reaction times similar to aspirin. Different extracts had different effects on paw edema in anti-inflammatory testing; some at first increased inflammation but eventually showed significant decreases, especially at higher dosages. These results offer a positive perspective on Verbesina encelioides' possible medicinal use. Conclusion: These results provide a positive perspective on Verbesina encelioides' possible therapeutic use. The results imply that extracts from Verbesina encelioides, which are abundant in bioactive substances such as flavonoids, phenolics, and alkaloids, may have applications in treating pain and inflammation. Prospects for the future: These results highlight the plant's medicinal potential and suggest that more research and development could help address pain and inflammation naturally.

Impact of a Near-Surface Plasma Region on the Bow Shock Wave and Aerodynamic Characteristics of a High-Speed Model in Xenon

The main objective of this study is to demonstrate the active influence on the location of the bow shock wave, as well as on the parameters of an aerodynamic body, of a gas discharge organized near the frontal surface, between the body and the bow shock wave. The research is carried out using both experimental and numerical methods at the freestream Mach number M = 6.8. The working gas is xenon. It is shown that the location of the steady bow shock wave, along with the current and power of the discharge, is associated with the change in the adiabatic index of the plasma created by the discharge, which, in turn, is determined by plasma parameters such as the degrees of nonequilibrium and the degree of ionization. It is shown that the adiabatic index with the power supplied to the impact zone in the range of 30–120 kW can both increase and decrease in the range of 1.25–1.288. A study of the discharge-created plasma zone is conducted, and the correspondence between the gas discharge current and power and the average parameters in the plasma zone created by the discharge are presented. A good agreement between the numerical and experimental data is shown. The results obtained can be useful in the development of control systems for high-speed flows based not only on the effects of heating but also on the impact of plasma parameters.

MHD casson fluid flow over a stretching surface with suction, double stratification, and heat and mass transfer effects

Abstract In this article, we investigated the flow of a magnetohydrodynamic Casson fluid across an extending surface with exponential permeability in a double-stratified medium. Thermal radiation, suction, heat sources, viscous dissipation, and chemical reactions drive the stream field. We converted the flow describing partial differential equations into terms of ordinary differential equations by applying appropriate transformations. Next, we utilised the bvp4c package in Matlab to obtain numerical solutions for these equations. We explored and graphically showed the implications of different non-dimensional governing parameters for temperature, concentration, and velocity profiles. After analysis, we provide a tabular presentation of the friction factor, Nusselt, and Sherwood numbers. The Casson fluid temperature shows a rising trend for the solutal stratification parameter and a decreasing trend for the thermal stratification parameter, while the Casson fluid velocity shows a declining trend towards both of these parameters. The Casson fluid concentration also behaves differently depending on the stratification parameter; for example, it increases for thermal stratification and decreases for solutal stratification. We notice that an increase in the Casson parameter's value suppresses the velocity field. However, as the Casson parameter increases, both the temperature and the concentration improve. Furthermore, comparisons with previously published findings also support the current results. \sethlcolor{yellow}\hl{The study of MHD Casson fluid flow that includes suction, dual stratification, and the effects of heat and mass transfer is very useful in many areas, such as polymer processing, metallurgical engineering, biomedical applications, environmental sciences, and advanced cooling technologies.

An enhanced heat transfer method based on the electrocapillary effect of gallium-based liquid metal.

As electronic products become smaller and more powerful, there is an increasing need for effective heat dissipation. An effective heat exchange method is necessary for the equipment to function reliably in a compact space. To tackle the limitations of current microfluidic cooling technology, including difficulty in manufacturing, maintenance, and cost reduction, a heat exchange method with a simple system is proposed in this work. This method is based on the electrocapillary effect, using eutectic gallium-indium alloy droplets with high thermal conductivity, surface tension, and controllability as the basic unit. An electric field is applied to generate unevenly distributed charges in the electric double layer on the droplet surface, thereby creating a surface tension gradient that can drive the surrounding solution to flow. Simultaneously, the oscillation of the droplet can also intensify the disturbance of the solution. The violent disturbance of the solution causes the heat transfer mode to change from conduction to convective heat transfer and greatly reduces the thermal resistance, resulting in a substantial increase in heat flux. For this heat transfer method, the temperature distribution and flow characteristics of the solution in low-frequency oscillating and direct-current-biased alternating current electric fields are studied, and the effect of voltage, frequency, and the number of droplets on heat transfer enhancement is clarified. Compared with conduction without internal disturbance, the heat flux can be increased by up to 110% based on the combined effect of two droplets. This work provides a solution for enhancing the heat transfer of microfluidics.

High Thermal Conductive Crystalline Organohalide for Endurable Resistive Switching Non-Volatile Memory.

The organic-based memristive devices are widely studied as a next-generation electronics for eco-friendly wearable applications, thanks to materials` flexibility and biocompatibility. However, poor operational reliability and stability of the devices remain a critical challenge. Here, the study demonstrates a crystalline organohalide, Dabconium ammonium triiodide (DABCO-NH4-I3, DABCO is 1,4-diazabicyclo[2.2.2] octonium)-based memristive device with exceptionally high reliability and endurance. Owing to the low dielectric constant and anisotropic hexagonal crystal structure consisting of hydrogen bonds with a high bandgap, the DABCO-NH4-I3-based conductive bridging random access memory device demonstrates millivolt-scale operating voltages with a remarkably high on/off ratio of ≈109, capable of multi-level storage. The relatively higher thermal conductivity of the crystalline organohalide (1.06Wm-1K-1), compared to most of organic materials (0.1-0.5Wm-1K-1), is found to be beneficial to suppress intense heat accumulation generated by Joule heating effect during device operation. With the facilitated dissipation of the generated heat, the simple planar heterojunction structured device shows remarkably endurable resistive switching over 103 cycles of program-erase at both room temperature and 85 °C with high switching reliability. This study introduced a new class of materials that can overcome the limitations of existing organic materials for high-performance next-generation organic electronic devices.

Thermo‐Mechanical Study on Auxetic Shape Memory Periodic Open Cellular Structures—Part I: Characterization of Reentrant Geometry and Effective Heat Conductivity

Periodic open cellular structures (POCS) are additively manufactured supports for heterogeneous catalysts in the field of chemical reaction engineering. Constructed from a repeated unit cell, POCS offer excellent heat transport characteristics due to heat conduction in the continuous solid matrix. However, when inserted into tubular reactors, a loose fit between structure and tube wall results. This considerably hinders heat transfer across the wall. The novel POCS concept presented in this work aims at an intensified wall heat transfer by utilizing a reentrant structure design to ensure auxetic behavior. If the POCS is made of shape memory alloy, it can recover its original shape. Combining these two effects with an initial radial oversize, an interference fit with the tube is established. This contribution comprises the geometric description of reentrant POCS and heat conduction simulations for characterization of the effective heat conductivity, yielding scaling correlations dependent on geometric parameters. Moreover, the effective radial heat conductivity of POCS in cylindrical shape is explicitly investigated. The influencing factor identified is the ratio of tube diameter and cell size: while the ratio increases, the effective radial heat conductivity decreases, but remains well above the effective heat conductivity of the unit cell.

The effect of surface roughness and carburized depth on wear resistance in 16MnCr5 case hardening steel

Purpose Today, wear and tear is a metaphor whose cost cannot be ignored by real sector. For this reason, many sectoral and academic studies are carried out to minimize the wear effect. This study aims to create a perspective against wear problems for the automotive industry as well. Design/methodology/approach The 16MnC5 material, which is used as the U-joint material in the powertrain of the automotive industry, was subjected to heat treatment such as normalization and carburization at certain temperatures and duration. By subjecting the resulting carbide thickness to the abrasion process, the maximum effective heat treatment parameters against wear were determined. Findings It has been determined that the ideal cementation condition for 16MnCr5 steel to be used in the wear system is carburized samples at 900 °C for 3.5 h with a hardness depth of 1.04 mm. Originality/value The variation in which the surface hardness thickness and surface roughness obtained by different heat treatment variations of the U-joint part, which is one of the cardan shaft components that provide power transmission of heavy commercial vehicles, show the best wear resistance, were investigated. As a result of this study, the study is to prevent the waste of limited materials in the world and to reduce the repair and maintenance costs of commercial vehicles.

CFD Simulation and Surface Modification of SG Cast Iron for Hot Rolling Applications

The wear resistance and heat dissipation of hot rolling mill rollers are critical factors affecting their durability and operational efficiency, particularly under extreme thermal and mechanical conditions. This study investigates the surface modification of SG iron rollers through tungsten laser cladding, aiming to improve these properties. A comprehensive approach, combining Computational Fluid Dynamics (CFD) simulations and experimental trials, was employed to evaluate the performance of tungsten-cladded rollers relative to untreated ones. The results revealed a 10-18% improvement in heat dissipation for tungsten-cladded rollers, attributed to enhanced heat transfer rates and better cooling efficiency. The analysis of fluid flow patterns, water volume fraction, and cooling angles demonstrated that tungsten cladding allowed for more effective heat management and uniform cooling across the roller surface. In the experimental trials, the mechanical properties of SG iron showed significant enhancement after laser cladding. The microhardness of the cladded surface increased by 59%, from 220 HV to 350 HV, offering improved resistance to surface deformation and wear. Furthermore, the wear resistance improved by 35% reduction in wear loss, as the tungsten and MoS₂/WC composite coatings provided a strong protective barrier against abrasion. Additionally, the Coefficient of Friction (COF) was reduced by 43%, from 0.7 to 0.4, due to the lubricating properties of MoS₂, minimizing frictional heat and energy loss during operation. These findings reveal the effectiveness of tungsten laser cladding as a surface modification technique for SG iron rollers, with practical implications for improving the durability and operational efficiency of hot rolling mill rollers.

Effect of Various Thermal Processing Methods on the Sensory, Textural, and Physicochemical Characteristics of Foal Meat.

Previous research on the impact of various heat treatment methods on meat has primarily focused on conventional meats from common livestock animals, with limited studies on the effects of different heat treatments on foal meat. The aim of this study was to evaluate how different heat treatments, including sous-vide, affect the sensory, textural, and physicochemical characteristics of foal meat. This allowed for the identification of the most effective heat treatment method to preserve the optimal quality attributes of foal meat while enhancing sensory and textural qualities preferred by consumers. Samples of m. longissimus thoracis were subjected to traditional cooking in two variants: in water at 100 °C in a foil bag for 1.5 h, and cooked to a core temperature of 85 °C (16 half-carcasses × 2 traditional heat treatment methods = 32 samples). Additionally, m. longissimus thoracis was subjected to sous-vide at 55 °C and 65 °C for 4 and 24 h (16 half-carcasses × 2 temperature settings × 2 time settings = 64 samples). Chemical composition, physicochemical properties, color parameters, hem pigment levels, texture characteristics, and sensory properties were analyzed. Compared to sous-vide samples, traditionally cooked foal meat exhibited higher weight loss (p = 0.002), higher fat content (p = 0.003), and lower water content (p = 0.03). Significant improvements in tenderness were observed in sous-vide samples, with the lowest shear force values (52.86 N/cm2 at 55 °C and 48.39 N/cm2 at 65 °C; p = 0.001) and meat hardness (102.44 N and 101.27 N, respectively; p = 0.015) after 24 h of thermal processing. Moreover, sous-vide cooking significantly improved sensory properties of foal meat, particularly juiciness (p = 0.002), tenderness (p = 0.002), and flavor desirability (p = 0.03), which were highly rated by consumers.

Design and Simulation of an Igniter for Surrounding-Type Underground In-Situ Coal Gasification

To optimize the gas passage of underground coal igniters and enhance the performance and efficiency of ignition heaters, meeting the demands of actual underground operations, this paper designs a set of annular ignition heaters. By simulating the internal gas flow within the igniter, the pressure distribution and velocity characteristics inside the igniter are analyzed. Utilizing combustion flow field simulation technology, a comparison is made between the heating and ignition effects of annular igniters and central igniters in coal heating. The performance of the deflecting tube under different eccentric angles is simulated to determine the optimal eccentric angle for achieving the best heating effect. The results indicate that annular igniters for underground in-situ coal gasification have significant advantages over traditional igniters in terms of wellbore heating and flame penetration, with the optimal eccentric angle of the igniter being 10°.

An exploratory study of household conditions and youth personal exposure to extreme heat during a heatwave in urban Nashville, Tennessee, USA.

Extreme heat is the deadliest meteorological hazard and is increasingly affecting the southeastern United States. Health effects of extreme heat are often not felt for hours or days after exposure and disproportionately affect vulnerable populations (e.g., youth, minorities). Personal heat exposure research has focused on occupational and everyday heat exposure among adults. To date, heat exposure in teenage populations has not been investigated. This population has unique heat exposure patterns that result from lifestyles that include outdoor jobs (e.g., lifeguard) and participation in outdoor sports. Better understanding of these exposure patterns is needed to reduce youth exposure and illnesses during heat events. Likewise, there have been no studies comparing paired indoor home conditions with individual exposure. Participants (n = 10) wore sensors to collect six days of personal heat exposure data (temperature and humidity) and placed sensors in and around their homes to collect ambient household data. When comparing individual exposure with ambient outdoor conditions and household conditions, this study revealed that: 1) teenagers are less exposed to dangerous heat (> 37.8°C heat index) during the day; 2) teenagers are more exposed to dangerous heat (> 23.9°C temperature) at night; 2) some teenagers are exposed to long periods of high heat at night, which is typically a time for heat recovery; and 3) household temperatures are typically not representative of heat exposure. To better understand teen exposure, we recommend future research focus on larger, representative sample sizes, collecting exposure data during the school year, and comparing exposure between heatwave and normal summer conditions.

Concept for a geometry-insensitive high-field magnetic resonance detector

AbstractWe introduce an inverse design methodology for a new class of eigenfrequency-invariant metamaterial-resonators, targeting nuclear magnetic resonance detection at ultra-high $$\mathbf {B_0}$$ B 0 field, and operating at two specified frequencies selected from within the 100-1500 MHz range. The primary optimisation goal is to maximise the magnetic field intensity and uniformity within a liquid sample, while the electric energy should be kept to a minimum level to reduce dielectric heating or quadrupolar moment excitation effects. Due to the symmetric geometry requirement of the cavity, a demultiplexer is also designed to direct each discrete resonant signal to another predetermined output port of the resonator. In order to reduce the geometrical dependency of the resonance frequency, a bespoke metamaterial is used for the cavity host. Therefore, an additional optimisation problem for a unit cell domain is defined to seek a proper material layout for the host region of the resonators. Given the sensitivity of the frequency domain, the optimisation process is effectively regulated through the utilisation of both a Helmholtz filter and a projection method. It is found that considerable improvements of the resonator quality factor can be obtained through this optimisation process.

PVA/CNT/PPy Aerogels for Driving Water Evaporation Through both Photo‐Thermal and Electro‐Thermal Effects

AbstractSolar‐driven interfacial water evaporation technology is considered as a promising clean water production strategy addressing the issues of global water pollution and scarcity. In this study, highly efficient polyvinyl alcohol/carbon nanotube/polypyrrole (PVA/CNT/PPy) aerogel evaporator is fabricated by combining hydrophilic PVA aerogel with superior water absorption property and carbon‐based fillers with coupled photo‐thermal conversion effects. By regulating the pore structure of PVA aerogel, the capillary effect is enhanced, thereby optimizing the water transport rate. Based on the photo‐thermal effect, the evaporation rate of the evaporator under one standard solar irradiation (1 kW m−2) is 3.17 kg m−2 h−1. Additionally, after the input of electrical energy, the heat converted from light absorbed by carbon‐based material can promote the Joule heating effect, and the synergistic effect further increases the evaporation rate of the aerogel to 5.59 kg m−2 h−1 when subjected to one solar irradiation combined with a 5 V input voltage. This electro‐thermal assistance enables efficient water evaporation even in low‐light and dark conditions. Furthermore, the PVA/CNT/PPy aerogel evaporator demonstrates significant potential in terms of desalination performance and long‐term stability.
