Authors: Wang Bo , Han Bei , Wang Ke , Cao Shengli
Published: July 2024

In order to ensure the flight safety of an aircraft and reduce the loss of humidity to the precision instruments and equipment in the aircraft, this study designs a small-size resonator antenna shape based on Radio Frequency Identification (RFID) technology and sensor principles. The resonator antenna makes use of the characteristics of the square ring and bent resonator and, at the same time, adopts the polyvinyl alcohol film with strong hygroscopic performance as the moisture-sensitive material. The equivalent resonant circuit of the sensor is constructed, and the parameters are optimized according to the principle of “coarse tuning of inductance parameters and fine tuning of capacitance parameters” to determine the optimal size. The relationship between the resonance frequency and the resonance response of humidity was investigated by the optimized model of the RFID resonator and polyvinyl alcohol (PVA). The simulation results show that as the relative humidity increases from 29.1 %RH to 90.9 %RH, the dielectric constant of the PVA film increases from 5.3 to 22 and the resonance frequency of the resonator decreases significantly from 4.74 to 4.12 GHz, with a total offset of 620 MHz, and the sensitivity is as high as 10.03 MHz/%RH. The results show that the designed sensor has a high sensitivity to humidity changes and a wide humidity detection range, providing an advanced solution for the detection and control of humidity inside aircraft.
Numerical investigation of the wave resonance and absorption inside side channels
Authors: Zhang Housheng , Zhao Xin
Published: July 2024

Wave resonance and absorption are typical phenomena in marine or coastal structures. This paper numerically describes the resonant absorption of water waves in a wave tank with two closely spaced resonant side channels mounted. Regular waves are produced on one end of the wave tank based on the momentum source function. The resonant modes around the symmetric and asymmetric channels are extracted and analyzed. Seven monitoring points near the channels are selected to study wave transmission and surface elevation characteristics. The first-order mode accounts for most of the wave energy and basically displays the energy distribution and wave transmission process. For resonant absorption, the channels pump water from the crest to the trough of the passing wave sequentially and periodically, during which wave energy is extracted and sustained in the channels; therefore, the amplitude of surface elevation in the channels increases sharply, which in turn promotes the loss of wave energy.
Expansion and growth of liquid bridge in saline water-in-oil emulsion under synchronized magnetic field coupled low-intensity electric field

Published: July 2024

Unconventional crude oil and offshore oilfield extraction often lead to the formation of stable oil–water emulsions with high mineralization, posing significant threats to environmental protection and pipeline transportation safety. Electric–magnetic coupling separation technology represents a novel approach to emulsion breaking, offering superior separation performance compared to the conventional electric coalescence methods. However, its underlying mechanism remains elusive. To address this gap, this study comparatively investigates the liquid bridge dynamic during droplet coalescence under a single electric field and electric–magnetic coupling field conditions. High-speed camera experiments reveal that synchronized coupled magnetic fields suppress the extension of liquid bridges, with this suppression effect being augmented by increasing ion concentration and electric field strength. Nevertheless, the enhancement of the inhibition effect is not pronounced at electric field strengths up to 224 kV m−1 and within the frequency range of 50–500 Hz. Molecular dynamics simulations demonstrate that the mutual repulsion effect between water molecules and the hydration effect between water molecules and ions are intensified under the coupling field. Finally, by integrating flow field and velocity analyses, a mechanism is proposed to elucidate the hysteresis in the evolution of liquid bridges, attributed to the mutual repulsion of water molecules hydrated by deflecting ions and convecting water molecules in the coupled field. This study offers valuable insights for the development of electric–magnetic coupling separation techniques, with implications for mitigating oil contamination and facilitating dewatering treatments.
Attached two-dimensional coherent vortices in a turbulent boundary layer
Authors: Zametaev V. B.
Published: July 2024

The turbulent boundary layer (TBL) of a viscous incompressible fluid that develops past the surface of a flat plate at finite distances from the laminar–turbulent transition zone is studied. It is assumed that the characteristic Reynolds number of the flow is large, and that the boundary layer is thin. An asymptotic method of multiple scales is used to find solutions to the Navier–Stokes equations. The velocities and pressure in the TBL are presented as a sum of steady and perturbed terms instead of the traditional decomposition into time-averaged values and their fluctuations. This article describes the process of generation of “inviscid” two-dimensional coherent vortices at selected points on the plate surface. Such solutions relate to the well-known Kraichnan's theory of two-dimensional turbulence, although they are derived as a particular case from three-dimensional analysis. A countable spectrum of possible “elementary” eigensolutions in the zone of turbulence generation near the streamlined wall is described. The evolution of generated coherent vortices is calculated numerically against the background of a steady basic longitudinal velocity profile over the entire thickness of the TBL. It is found that longitudinal, time-averaged velocity perturbations have logarithmic behavior close to the wall. The coefficients of these logarithmic terms are calculated, which makes it possible to find the local coefficients of skin friction on the streamlined surface. A satisfactory comparison with classical experimental data is made.
Vortex energy behaviors in the forebay of lateral pumping station for Y-type channel
Authors: Luo Can , Zhang Li , Wang Tieli , Liu Hao , Cheng Li , Lu Mingzhi , Jiao Weixuan
Published: July 2024

Vortices always happen in the forebay and sump of a lateral pumping station, reducing its efficiency and wasting extra electric power. This study utilizes computational fluid dynamics (CFD) technology and a model test method to investigate the distribution of vortices in the forebay of a lateral pumping station of Y-shaped channel. Since the vortex is always accompanied by energy dissipation, the entropy production theory is also introduced to analyze the energy behaviors of the anti-vortex bottom sill. The research results indicate that the model test results verify the accuracy of the CFD. The bottom sill can effectively improve the flow pattern and reduce the rolling vortex behind the sill in the forebay, enhance the axial velocity uniformity at the inlet section of the sump, and reduce energy loss. The high entropy production zone is mainly distributed in the vortex core and the top of the sill. Therefore, the vortex and shock are the main causes of energy loss. The square bottom sill causes more severe energy loss compared to the trapezoidal bottom sill. The research results can provide references for setting up hydraulic optimization measures for similar lateral pumping stations.
Slow polymer dynamics in poly(3-hexylthiophene) probed by muon spin relaxation

Published: July 2024

The molecular dynamics of regioregulated poly(3-hexylthiophene) P3HT is investigated using muon spin relaxation (μSR). The response of the μSR spectra to a longitudinal magnetic field (BLF, parallel to the initial muon spin direction) indicates that the implanted muons form both muonated radicals localized on the thiophene ring and diamagnetic states with comparable yields. Moreover, the unpaired electron in the radical undergoes hyperfine interactions with muon bound to thiophene and with neighboring protons, whose fluctuations can serve as a measure of the molecular dynamics. The BLF dependence of the longitudinal muon spin relaxation rate (1/T1μ) measured in detail at several temperatures is found to be well reproduced by the spectral density function J(ω) derived from the local susceptibility that incorporates the Havriliak–Negami (H–N) function used in the analysis of dielectric relaxation, χ(ω)∝1/[1−i(ω/ν~)δ]γ (where ν~ is the mean fluctuation rate and 0<γ,δ≤1). The magnitude of ν~ and its temperature dependence deduced from the analysis of 1/T1μ are found to be consistent with the motion of hexyl chains and thiophene rings suggested by 13C-NMR. The present result marks a methodological milestone in the application of μSR to the dynamics of complex systems with coexisting fluctuations over a wide range of time scales, such as polymers.

Universal scaling in far-from-equilibrium quantum systems: An equivalent differential approach
Authors: Madeira Lucas , García-Orozco Arnol D. , Moreno-Armijos Michelle A. , Fritsch Amilson R. , Bagnato Vanderlei S.
Published: July 2024

Recent progress in out-of-equilibrium closed quantum systems has significantly advanced the understanding of mechanisms behind their evolution toward thermalization. Notably, the concept of nonthermal fixed points (NTFPs)—responsible for the emergence of spatiotemporal universal scaling in far-from-equilibrium systems—has played a crucial role in both theoretical and experimental investigations. In this work, we introduce a differential equation that has the universal scaling associated with NTFPs as a solution. The advantage of working with a differential equation, rather than only with its solution, is that we can extract several insightful properties not necessarily present in the solution alone. How the differential equation is derived allows physical interpretation of the universal exponents in terms of the time dependence of the amplitude of the distributions and their momentum scaling. Employing two limiting cases of the equation, we determined the universal exponents related to the scaling using the distributions near just two momentum values. We established a solid agreement with previous investigations by validating this approach with three distinct physical systems. This consistency highlights the universal nature of scaling due to NTFPs and emphasizes the predictive capabilities of the proposed differential equation. Moreover, under specific conditions, the equation predicts a power-law related to the ratio of the two universal exponents, leading to implications concerning particle and energy transport. This suggests that the observed power-laws in far-from-equilibrium turbulent fluids could be related to the universal scaling due to NTFPs, potentially offering insights into the study of turbulence.
Temperature-dependent electron–phonon coupling changes the damage cascades in neutron-irradiation molecular dynamics simulation in W
Authors: Shin Younggak , Kang Keonwook , Lee Byeongchan
Published: July 2024

We present a first-principles-based electron-temperature model that can be used in atomistic calculations. The electron–phonon coupling coefficient in the model is derived from the density of states as a function of electron temperature, and the thermal conductivity of tungsten from our model shows significant improvement over the baseline atomistic calculations in which only ion-thermal contribution to the thermal conductivity is available. The correction to the thermal conductivity also changes damage cascades as cascades cool down more rapidly within our model. The mobility of defects is consequently reduced, leaving more residual damage than the predictions without an electron-temperature model.

Published: July 2024

To help meet its near-term NDC goals and long-term net-zero 2070 target, the Government of India has planned to establish a Carbon Credit Trading Scheme (CCTS), i.e. a domestic emission trading scheme (ETS). An ETS is an inherently cost-effective policy instrument for emission reduction, providing the greatest flexibility to reduce emissions from within and across sectors. An effective ETS requires design features that consider country-specific challenges and reflect its role within the larger policy package to achieve long-term emission reduction. Within the Indian context and in this study we therefore investigate—(i) what might be the role of the ETS in achieving India’s long-term mitigation targets? (ii) How might the various sectors interact under an emissions cap? (iii) How might the ETS interact with existing energy and climate policies? We do this analysis by running four main scenarios using the integrated assessment model GCAM (v6.0), adapted to India-specific assumptions and expectations. These scenarios are—(i) NZ (net-zero), (ii) NZ + ETS, (iii) NZ + CC (command and control), and (iv) NZ + RPO (renewables purchase obligations) + ETS. The NZ scenario assumes India’s near-term and long-term climate commitments of net zero by 2070. Scenarios with ETS (ii) and (iv) apply an emissions cap on four sectors—electricity, iron and steel, cement, and fertilizer. The scenario with CC applies a homogenous emission cap on each of the chosen sectors but does not allow cross-sectoral trading. The last scenario includes renewables purchase obligations (RPOs along with an ETS. We show that under a specific ETS emissions cap: (i) the electricity sector emerges as the largest source of cost-effective greenhouse gas (GHG) reduction options; (ii) ETS with trading across sectors is around 24% more cost-effective than ETS with trading only within sectors, (iii) RPOs can be complementary to an ETS although the impact of RPOs on GHG reductions in the electricity sector would need to be considered when setting the level of the ETS cap (or emissions intensity targets) or the RPO targets to avoid low carbon prices, and (iv) the direction and volume of financial transfers across sectors depends on allocation targets set by the government. Based on these results we provide design recommendations for India’s ETS.
Special function models of indecomposable sl(2) representations: the Laguerre case
Authors: Bertrand Sébastien , Marquette Ian , Miller Willard , Post Sarah
Published: July 2024

In this paper, we point out connections between certain types of indecomposable representations of sl(2) and generalizations of well-known orthogonal polynomials. Those representations take the form of infinite dimensional chains of weight or generalised weight spaces, for which the Cartan generator acts in a diagonal way or via Jordan blocks. The other generators of the Lie algebras sl(2) act as raising and lowering operators but are now allowed to relate the different chains as well. In addition, we construct generating functions, we calculate the action of the Casimir invariant and present relations to systems of non-homogeneous second-order coupled differential equations. We present different properties as higher-order linear differential equations for building blocks taking the form of one variable polynomials. We also present insight into the zeroes and recurrence relations.
Making tourism livelihoods sustainable: An assessment of community livelihood assets as impacted by the COVID-19 pandemic
Authors: Alcantara R C D
Published: July 2024

Barangay Cagbalete Uno is a rural village found in the island of Cagbalete, Mauban, Philippines whose local livelihoods are largely based on tourism activities. Due to the adverse impacts of COVID-19 to the tourism industry, this paper examined the change in livelihood assets of Cagbalete Uno before and during the pandemic to assess how sustainable tourism livelihoods in the island are. Using the Sustainable Livelihoods Framework (SLF), the livelihood assets pentagon showed a significant decline in all capitals. The financial capital had the most significant decline, followed by the social, human, natural, and physical capitals. The experience of the local community revealed that the availability and access to one capital affected the availability and access to the other capitals. Therefore, designing sustainable livelihoods should aim to understand and enhance all livelihood assets in the community. Additionally, the dependence of tourism on external stakeholders can make communities more vulnerable. Therefore, instead of displacing them, tourism development should enhance other livelihood activities in a destination.

The Factors Affecting Environmental Sustainability Behaviour in the Malaysian Hotel Industry
Authors: Lim C S , Teoh S Y , Kuar L S
Published: July 2024

Recently, environmental sustainability has become a critical topic in the 21st century. Responsible tourism prioritises resource efficiency, community involvement, and biodiversity. This aligns with the overarching objective of advocating for practices that support environmental sustainability. Environmental degradation is caused by massive urbanisation, industrialization, and deforestation, which has led to greenhouse effects, global warming, climate change, acid rain, and pollution at alarming levels. Studying human attitudes and behaviour is crucial for understanding how people think about environmental and sustainability issues. Therefore, this study developed five hypotheses with four independent variables (personal values, environmental knowledge, environmental awareness, social norms and environmental attitudes) and a dependent variable (environmental sustainability behaviour) focusing on employees in the Malaysian hotel industry. It utilized quantitative techniques through questionnaires to collect responses and examine the proposed hypotheses in order to achieve the research objectives. A total of 234 questionnaires were collected from hotels in Malaysia and analyzed using PLS-SEM. The findings indicated that personal values, environmental awareness and environmental attitudes had a significant relationship with environmental sustainability behaviour while environmental knowledge and social norms were not significantly related to environmental sustainability behaviour. The study provides theoretical and practical implications for policymakers and industry practitioners.

Authors: Mapalad G
Published: July 2024

Many areas in the Philippines are identified as potential ecotourism sites. For sustainable tourism development or site management, a carrying capacity analysis can ensure low and manageable environmental impacts, accommodate a high level of visitor satisfaction, and give stakeholders and local communities adequate economic returns. This study’s findings describe the carrying capacity of ecotourism attractions in Tablas Island, Romblon. It used a descriptive mixed method of research with 63 respondents selected using purposive and quota sampling techniques, and a GIS map was constructed to illustrate the physical geography and fundamental attributes needed to estimate the capability of the sites. The venues’ carrying capacity estimate was computed using Boullon’s Tourism Carrying Capacity Model. The results revealed respondents’ standard visitor requirements ranged from 1.43 m2 to 2.14 m2 to 2.86 m2. Most of them only required 1-2 hours but some needed as much as 4-5 hours to really enjoy their activities. The sites’ determined tourism carrying capacity is 1,157 visitors/day for Dubduban Falls in San Agustin; 612 visitors/day for Mablaran Falls in San Andres; and 138 visitors/day for Tuburan Falls in Odiongan. These results can be used to improve tourism site development in Tablas Island, Romblon.

The purpose of this paper is to investigate the role of tourism (geopark) development support in mediating the relationship between economic and socio-cultural benefits perceived costs of tourism (geopark) development, and community well-being in the context of Kinabalu UNESCO Global Geopark in Sabah, Malaysian Borneo. According to the study’s findings from 301 participants, economic and socio-cultural benefits have a significant impact on community well-being, and support for geopark development partially mediates the relationships. However, perceived costs did not have influence on community well-being. The study theoretically extended and enriched the literature on geopark development by emphasising the significance of including community well-being in the conceptualization. In regard to the contribution to policy makers, the study revealed the importance of inclusive policy in developing strategic geopark development.
Operational monitoring method using drones for smart and precision Sumatran elephant tourism
Authors: Rahman D A
Published: July 2024

Travelers and the public can now use drones. High-quality drone cameras provide spectacular aerial photos and videos. However, drones’ effects on wildlife behavior must be considered. The researcher conducted a study to assess the feasibility of using DJI Matrice 300 RTK equipped with thermal sensors as aerial survey platforms for tourist purposes in the Bukit Tigapuluh Landscape, specifically focusing on the Sumatran elephant. In order to evaluate the efficacy of drones in detecting the presence of wild elephants and monitoring their behavior intelligently and precisely as the main attraction of tourism, The researcher collected data on the optimal altitude, temperature, and duration of flight. The researcher measured optimal flight altitude, temperature, and duration. Elephants can be detected at above 70 meters above ground level (AGL) if the sound intensity is within their tolerance. Elephants identified had body temperatures of 28-30°C. The thermal infrared scans showed them clearly in the morning and evening, when the temperature was below 28°C. They were harder to spot during midday when temperatures approached 30°C. Drones enable rapid, precise, and frequent monitoring of narrow to wide areas with high-resolution spatial while providing presence data and recording species activity, and will provide new and interesting tourist experiences. Adhering to operational techniques for flying drones that do not disturb and change elephant behavior is critical to using this technology to provide a tourist experience of seeing wild elephants with minimal risk.
Responsible tourism in birdwatching and wild bird photography
Authors: Mardiastuti A , Mulyani Y A
Published: July 2024

Birdwatching and wild bird photography lately has been flourished, and on many occasions might cause some negative impact on the birds and their habitat. This paper explores the type and the nature of activities that usually done by birdwatchers or photographers and provide some suggestions how to be responsible birdwatchers/photographers to minimize the negative impact on birds. Information was collected from literature study and personal experience as birdwatchers and bird photographer, then analyzed to characterize the responsible birdwatchers/photographers. Birdwatchers or photographers can be categorized as hard core (advance), enthusiastic (intermediate, novice) and casual. Risks on birds may come from visitor’s intrusion and manipulation to get better photo or video images, including baiting/feeding, play-back, flushing, artificial spotlighting, and staging. To be responsible birdwatchers or photographers, those manipulation and some other prohibited actions such as disturbing birds/nestling/nest/nest site, approaching too close, touching, capturing, removing, killing, taking bird parts, making loud noise, and other harmful activities should be avoided. All types of birdwatchers or photographers must be responsible to their activities to ensure that the birds would not be disturbed, feeling stressed, alter their behavior, and decrease productivity. For a rare and protected wild bird species, posting of geolocation should be prevented

Published: July 2024

DKI Jakarta as capital city, must balance urban growth and environmental conservation. Green open space in cities helps preserve ecosystem balance and support biodiversity, including butterflies. This study will collect data on DKI Jakarta’s green spaces to develop butterfly-based ecotourism to enhance ecological tourism and address environmental conservation issues. Epicollet5 mapped exploration and trapping data. In five green places, 32 butterfly species from five families were found. In Srengseng Urban Forest, 18 species were found: Tebet Ecopark, Penjaringan Urban Forest, and Monas Urban Forest, 17 species each; and in Condet Agrotourism, nine were found. The Nymphalidae family (14 species) had the highest number of species, while the Hesperiidae family (2 species) had the lowest number. Overall, green open spaces have species diversity in the medium category (ranging from 2.55-2.79), with the highest value in Srengseng Urban Forest and the lowest in Condet Agrotourism. The evenness index reveals a reasonably even amount of butterfly species in each place, while the dispersion index displays butterfly types. This is indicated by the low evenness index (≤30%) between locations. The range of butterfly species seen throughout the study location suggests that urban ecotourism could capitalise on this biodiversity.

Published: July 2024

Marine tourism is one of the industries that has grown substantially during the previous decade. Pesisir Barat Regency, Lampung province, Indonesia, is a region with significant potential for marine tourism. Unfortunately, tourism has both beneficial and detrimental effects. This study intends to quantify the economic gains experienced by the locals and to diagnose the sustainability index in two separate marine tourism destinations in Pesisir Barat. Data analysis assesses the economic advantages of tourism income (sharing and covering) on household expenditure. Labuhan Jukung Beach has a tourism income contribution of more than 75% of the household income. It means that tourism is the primary income for the community. However, compared to Pulau Pisang Beach, both from tourism business actors and workers, the share and covering values obtained are low. The low economic benefits received will affect how people behave towards tourism. Since the community depends on the income from tourism, it is critical to work toward tourism sustainability and household participation due to SDGs 1 (no poverty) and 14 (life below water). The overall sustainability index in all assessment dimensions is greater at Labuhan Jukung Beach than at Pisang Island, as well as the economic benefit of tourism for the community.

Intangible cultural heritage protection from the perspective of cultural tourism: a case study of Shaanxi Province, China
Authors: Jiawei A Z , Mustapha B A
Published: July 2024

Amidst China’s ongoing economic growth, the demand for public cultural resources has significantly risen, highlighting disparities in supply and demand. To address this issue, public cultural service reform is imperative. This article focuses on the consolidation of public cultural resource class scenic spots and their attributes. It outlines the theoretical foundations of free access to such resources and examines their positive impacts on the economy, society, and tourism. However, this approach also poses challenges, such as disrupting the economic balance of scenic areas, reduced enthusiasm for opening these spots, management difficulties, and unsustainable visitor growth. The study delves deeper into these challenges by using Xi’an Datang Furong Garden Scenic Spot as a case study, exploring how government can effectively manage public cultural resources, balance economic interests, and promote scientific protection and sustainable utilization. The paper suggests increasing financial subsidies, developing service projects, resource and environment protection, optimizing management mechanisms, and enhancing the industrial structure to ensure the sustainable development of free scenic spots. This research holds significant practical relevance.

The tourists’ contribution to sustainable tourism is not only economic but also in socio-cultural and ecological aspects. As a medium for Instagram content for National Parks in Indonesia, virtual tours contain content to inform and promote that can influence tourists to realize sustainable tourism. Research to evaluate the content of virtual tour narratives is carried out with a quantitative descriptive approach. The quantitative method involves frequency analysis and score calculation for meeting virtual tour evaluation criteria, while the results are explained descriptively. The analysis technique used is content analysis with information and promotion messages of narrative elements evaluation criteria. The results showed that the percentage of virtual tour video content on National Park Instagram in Indonesia was less than content that was not virtual tour videos. The small number is also not accompanied by good narrative elements, only 15% of which have excellent evaluation results. However, two National Parks can optimize virtual tours, Karimun Jawa and Komodo. Increasing the amount of video content, meeting information, and promotion criteria need to be done to optimize virtual tours in National Parks in Indonesia. The results can be used as a guide for evaluating the narrative elements of national park virtual tour videos.

This paper aims to investigate how the political economy of tourism development at the national level is affecting the management of a World Heritage Site, its rural localities and the surrounding communities. The study focuses on Borobudur priority tourism destinations, which is designated as part of Indonesia’s efforts to increase international tourists’ arrivals Various development programs - mainly physical and infrastructural take place in a bid to push more tourism activities in this World Heritage Site. Some of these recent developments have brought concern for the preservation of the site and values attached to it. This study uses interviews to gather information from representatives of organizations at local, national, and international level involved in the preservation of the cultural heritage site, tourism, and in managing the priority destination. The results indicate that the cultural heritage site is affected by the apparent political economy of tourism in which tourism interests dominate the decisions and policies concerning the area. There are also issues of unclear shared vision about the priority destination translated into action plans and division of responsibilities among institutions involved, indefinite decision on the institution to lead the management, and differing perceptions of development where the dominant notion is physical and infrastructural development.
Magnetically tuned thermoelectric properties of metal-oxides: a review
Authors: Dubey Divya Prakash , Chatterjee Ratnamala
Published: July 2024

In recent years, research on thermoelectric materials has garnered considerable attention, owing to their potential to offer efficient and environmentally friendly energy solutions. Metal oxides have emerged as strong contenders for thermoelectric materials, offering a promising avenue for implementing diverse mechanisms aimed at achieving higher thermoelectric efficiency. In this review, we investigate the influence of magnetic fields on the thermoelectric properties of oxide-based materials. Drawing insights from existing literature, we provide a comprehensive overview of how magnetically tuned Seebeck coefficients, thermal conductivity, and electrical resistivity impact the thermoelectric performance of oxide-based thermoelectrics. Literature available on magnetic field tuning of Spin Seebeck effect and anomalous Nernst effect for improved efficiency in oxide-based systems, have also been included in this review.

space group. Scanning Electron Microscopy indicates that the synthesized samples possess homogeneous surfaces with fewer pores. The sample with 3% Ni exhibits an approximately eight-fold increase in electrical conductivity than the pure sample at 307 K. However, the addition of Ni decreased the Seebeck coefficient, resulting in a lower overall power factor (PF) for the composites. The highest PF of ∼420 μW/mK2, was observed in the pristine sample at 570 K. Although Ni addition improves electrical properties, it negatively impacts the overall thermoelectric performance due to the significant reduction in Seebeck coefficient, thereby lowering the overall power factor.

Published: July 2024

The utilization of industry by-products, such as fly ash, was investigated. However, the research results have yet to report the functional characteristics of fly ash. This paper deals with the processing, microstructure, and functional characterization of fly ash using a novel powder metallurgy method. The elemental composition, mineralogical phases, morphology phases, electrical and dielectric properties were determined by XRF, XRD, SEM, and impendence analyzer, respectively. The effect of additives on fly ash’s microstructure and functional properties was studied. As a result, sintered fly ash possesses better microstructure and dielectric properties as a function of frequency and temperature. It is suggested that sintered fly ash can be utilized for electronic packaging and EMI shielding applications.
