DIGITAL TWIN COLLABORATION: A COMMON TECHNICAL STRUCTURE FOR THE AUTOMOTIVE AND THE BUILDING INDUSTRY
Authors: Braun Luisa , Mock Jennifer , Jung Louisa , Böttcher Peter , Scholzen Frank
Published: June 2024

During the planning stage of production sites for the automotive industry, the building industry and the automotive industry clash. Nevertheless, the planning in both industries is generally done separately and there is not enough communication which leads to problems later on in the process. In the automotive industry, the digital twin is already used as a common tool for the planning and simulation of production lines. In the building industry however, the digitalization is not as well-advanced. Since the workflows, the degree of digitalization and the used software tools differ so much, the combination of the different processes and data of the automotive industry and the building industry is still very difficult nowadays. In order to solve that problem, the aim is to develop a common structure that allows both industries to collaborate and share their data, starting early on in the planning process. The current workflows of both industries were analyzed by conducting interviews with experts in their field. Evaluation of the answers and further discussion in the interdisciplinary team of the research project “CoLab4DigiTwin” showed that the workflows of both industries actually have the similar approach of starting the planning process by thinking in three-dimensional spaces that get more detailed information over time. Based on this finding, a hierarchical technical structure was developed, combining the spaces of the building industry and the automotive industry. This structure acts as a clear common base that facilitates an organized data exchange and improves the interdisciplinary collaboration.
MECHANICAL PROPERTIES OF LAMINATED BAMBOO LUMBER MADE OF TROPICAL SPECIES
Authors: Rittironk Supreedee
Published: June 2024

Bamboo has been the trend for a sustainable material, due to its renewability. Bamboo can grow abundantly throughout the tropical area of the world, such as Latin America, East Asia and Southeast Asia. It is seen that Southeast Asia has variety of bamboo to utilize and many of them are suitable for structural applications. One additional reason is that they are clumping type, so fibers are built stronger. Bamboo is hollow and irregular in sizes and shapes, so it cannot maximize the use out of the materials. Bamboo Laminated Lumber (LBL) is the product to solve bamboo issues on the irregularity be transforming into solid lumber. It can be called the engineered bamboo, which have been transformed conventional form of bamboo using engineering process. This is the same technology as laminated timber. It has more potential to substitute the use of timber. This research is to experiment of making LBL using structural bamboo species that are widely used in Southeast Asia. They are Dendrocalamus Asper, Dendrocalamus Sericeus, Bambusa Multiplex, and Bambusa Blumena. They are tested for mechanical properties; Tension, compression parallel to grain, compression perpendicular to grain, and bending. Those properties are compared to other tropical hardwood and engineered wood. The result shows that LBL of all species are qualified for medium-hardwood quality, while B.Multiplex lumber performs best overall. The rest still have great mechanical properties and can be qualified some structural lumber in order to reduce the use of timber.

Published: June 2024

In recent decades, there has been a notable upswing in the production of construction and waste, posing significant challenges to the construction industry and jeopardizing environmental sustainability. The successful implementation of construction and demolition waste management (CDWM) strategies is hindered by various barriers within the construction industry. Addressing this issue requires identifying and prioritizing key factors contributing to waste generation. Consequently, this study seeks to pinpoint and assess the factors influencing construction waste generation in the Turkish construction sector. Initially, a systematic literature review was conducted, resulting in the identification of 54 factors. Subsequently, a 5-point Likert scale questionnaire was administered to project architects, project engineers, site supervisors, and contractors within the Turkish construction industry, with 162 respondents. The collected data underwent reliability analyses using SPSS 22 software. Following this, index of relative importance (IRI) analyses was employed to rank the identified factors. Ultimately, this study establishes the most significant factors responsible for construction waste generation in the Turkish construction industry.
THE CARBON-REINFORCED CONCRETE BUILDING – CUBE | BOX MANUFACTURING AND ASSEMBLING
Authors: Frenzel Michael
Published: June 2024

The world's first building made entirely of non-metallic reinforcement was constructed in Dresden, Germany in 2022. It will be 220 m² in size and represents the entire process chain of carbon reinforced concrete construction. In Germany's largest construction research project C³-Carbon Concrete Composite, the topic of carbon reinforced concrete and its implementation have been researched and tested since 2014. All the research results were culminated in a lighthouse project, the C³ technology demonstration house CUBE. Based on these results, the boundary conditions for material, form and construction were derived and the necessary structural, experimental and design verifications were provided as well as the approvals for the construction of the building were granted. This paved the way for further new construction projects. Originally planned as an actual cube, architect of HENN Architects gave the CUBE a bit of a twist. And so, an interplay of two essential elements was created: the double-curved striking TWIST shells and the clearly structured BOX. In order to successfully realize the demonstration house CUBE, science and industry combined their competences in carbon reinforced concrete construction. Above all, the BOX precast complex demonstrates the extraordinary and immediate application potential of this composite material. The BOX, described in this paper, consists of semi-precast wall elements and precast slabs that can be manufactured with component thicknesses of just a few centimeters due to the use of carbon reinforcement. Manufacturing technology was tested in an automated precast plant and assembly was implemented at the construction site.
STRAIN MEASUREMENT AND ADHESIVE SELECTION FOR STRAIN GAUGES ON CARBON ROVING IN TEXTILE-REINFORCED CONCRETE STRUCTURES
Authors: Polienko Wladislaw , Tekle Biruk Hailu , Holschemacher Klaus
Published: June 2024

Textile-reinforced concrete (TRC) is a promising building material that meets modern environmental protection and sustainability requirements. For the widespread use of this innovative building material, empirical models based on material properties determined by laboratory tests are needed. This study investigated the ability to measure the strain of carbon rovings with small strain gauges during standard tensile tests. The measured values were compared and validated using the digital image correlation (DIC) method. Another component of this study is the investigation of a suitable adhesive for the application of the sensors to SBR-coated (styrene-butadiene rubber) carbon roving. Three test series with three different adhesives, cyanoacrylate adhesive, epoxy resin, and polychloroprene, were produced and tested for tensile strength. The validation tests showed that a strain loss occurs in the adhesive joint of the strain gauges. It was found that cyanoacrylate adhesives, such as M-Bond 200, suffered the lowest losses and are recommended for further investigations. The epoxy resin influences the stiffness of the carbon fibers at the contact surface too strongly, while the polychloroprene adhesive could not transfer the actual roving strain due to insufficient stiffness of the bond line.
IMPACT OF ALUMINOSILICATE WASTES ON THE HYDRATION, PHYSICAL AND MECHANICAL PROPERTIES OF CEMENT PASTE
Authors: Antonovič Valentin , Sikarskas Donatas , Boris Renata , Malaiškienė Jurgita , Stonys Rimvydas
Published: June 2024

The impact of aluminosilicate wastes (spent fluid catalytic cracking catalyst from oil companies and metakaolin containing waste from the production of expanded glass granules) on the hydration and compressive strength of the cement paste was analysed when a proportion of cement was replaced by one waste material or two waste materials. The article presents results of X-ray diffraction and thermal analysis of hardened cement pastes. It was determined that the spent catalytic cracking catalyst accelerates cement hydration because of its high surface area and pozzolanic activity; and metakaolin containing waste has a retarding effect. X-ray diffraction and thermal analysis showed that the specimens with metakaolin containing waste had the lowest amount of portlandite, and the compressive strength of these specimens was similar to that of the control specimens when a superplasticizer was used. It was found that a mix of aluminosilicate wastes has a different effect on cement hydration and makes it possible to adjust the hydration time of the binder within a certain interval.

Published: June 2024

Exponential growth in the world population and increase in demand for concrete are pressing researchers and scientists to find sustainable alternative materials for Portland cement and natural aggregates. Self-leveling mortar is extensively used in construction applications, such as floor leveling, repair, resurfacing, or adhesion. Yet, limited research has been carried out on enhancing this material’s sustainability. This paper aims to produce a geopolymer mortar produced with fly-ash (FA), ground granulated blast furnace slag (BFS), and desert dune sand. Geopolymer mortar samples were produced with different binder-to-sand (B:S), FA-to-slag (FA:BFS), and alkali-activator solution-to-binder (AAS/B) ratios. Alkaline solution was blended with sodium silicate and sodium hydroxide with a molarity of 8 M (ratio of 1.5). Fresh and hardened properties of the developed self-leveling mortars were assessed. Experimental results showed that the flow, initial and final setting time, and 7-and 14-day compressive strength were in respective ranges of 17.3-40.3 cm, 21-155 minutes, 42-221 minutes, 6.0-70.3 MPa, and 5.2-78.7 MPa. Furthermore, an increase in FA:BFS, B:S, and AAS/B ratios enhanced flowability and prolonged setting time but reduced compressive strength at both ages. These research findings advocate the use of a self-leveling, cement-free geopolymer mortar to be utilized in various buildings and repair applications.

Published: June 2024

Due to increased project complexity and technological advancements in the last decade, designers and contractors are expected to render more effort to achieve the challenging project goals. To elicit extra efforts from agents, incentivization has become one of the primary strategies employed by clients. Despite increased academic interest in the design of incentive strategies, results of incentivization on project performance remain mixed. This study aims to reconcile these observations through a systematic review of existing literature on construction incentivization. Accordingly, the following research objectives are achieved: (1) examining the main purposes of using incentives, (2) identifying types of incentives are used in construction projects, and (3) evaluating the impacts on project performance that are derived from the use of incentives. Based on the results of the literature review, a framework to study construction incentivization is developed. This study offers a detailed framework to map the types of incentives with the expected outcomes.

Our study looks into a specific program designed to bolster the teaching capacities of new faculty in foundational construction topics. The central aim was to understand the opinions of CME faculty regarding these development initiatives and their potential benefits. During the summer of 2022, we introduced the program to 15 early-career faculty members. These individuals participated in educational sessions led by experienced construction educators. To gather feedback, we collected personal reflections and insights from participants, aiming to understand their perceptions and the impact on their teaching and mentoring skills. The feedback highlighted areas for improvement in current CME teaching practices and affirmed the value of such development programs. This research provides guidance for those in CME looking to design educational tools to better prepare graduate students for academic roles.
CIVIL LITIGATION AND DISPUTE RESOLUTION DURING URBAN TUNNEL CONSTRUCTION CAUSED BY PROPRIETY DAMAGE
Authors: Provenzano Paola , Iddas Giuseppe
Published: June 2024

Tunnel construction has to interact with many complex variables, both in the design phase and in the construction phase, especially in urban areas with high population density. Thus, building a new metro line inevitably involves disputes. Even if companies have appropriate guarantees provided in the contract, the initiation of a claim normally involves a dispute, which can be resolved, through confrontation of the parties, or it can incur court proceedings. During the construction of Milan's new subway line, Metro Blu, a great deal of effort was devoted to the management of damage complaints, induced mainly during the excavation phases and beyond. Thanks to the effort and commitment of numerous insurance companies, which supported the contractors, damage claims were collected and managed, almost always in conjunction with construction. Some disputes have been settled; others have resulted in court disputes. Although the most frequent claims have been for damage to the existing building (fractures and deformations), some disputes have involved claims for damages in relation to property rights and compensation for property expropriation. The authors expose two cases history of recurring disputes involving the construction of the new subway line, with the aim of reflecting on the patterns of large-scale litigation.

Published: June 2024

This study details a seismic risk assessment of stone and adobe masonry structures in the Agios Dometios Municipality, Nicosia, Cyprus. The study integrates field inspections using the PRISM survey form, designed exclusively for masonry buildings, with advanced analytical procedures. The initial phase involves comprehensive field inspections to evaluate the structural condition and vulnerabilities of these historic masonry buildings. The data gathered from these inspections provide essential insights into potential seismic risks. This data, alongside fragility curves generated from 3D finite element (FE) models using nonlinear time-history analysis, informs the creation of seismic risk maps for Agios Dometios. These maps offer a comprehensive depiction of the area's seismic vulnerability, particularly concerning the masonry structures, serving as invaluable resources for local authorities and conservationists in strategizing preservation and reinforcement measures, and in formulating mitigation plans. This study's approach, blending field inspections with advanced computational analysis, provides a robust framework for assessing the seismic risks of masonry structures. It holds significant implications for preserving architectural heritage in seismically active regions, offering a model that can be replicated in similar urban contexts.
WRAPPING PROCESS FOR BUILDING COMPONENTS MADE OF GLASSFIBER-AND TEXTILE-REINFORCED CONCRETE
Authors: Kufner Fabian , Rucker-Gramm Petra , Horstmann Michael
Published: June 2024

In the research project WiFaPu (wrapping process for highly fiber-reinforced concrete using the example of a pump sump) a wrapping process has been developed that combines the advantages of glassfiber-reinforced concrete and textile-reinforced concrete in terms of manufacturing processes and composite load-bearing behavior. In this process, a fine-grained concrete is sprayed with chopped-in short fibers on a carrier sheet and the textile reinforcement to produce a thin glassfiber-and textile-reinforced concrete layer with a defined thickness. This layer is continuously wrapped up onto a formwork to obtain a pump sump with an arbitrary cross-sectional thickness. The paper reports on the challenges in the development of the wrapping process and the associated coordination of the material components to produce durable members with monolithic blow-hole cross sections, acceptable surfaces and a reduced CO2 footprint. Pump sumps are produced as demonstrator components of the process. Their load-bearing capacity as well as their suitability for use are investigated in component tests. According to the experimental load tests, components with a high load-bearing capacity are produced. Filling tests show the overall high-water impermeability of the thin-walled components. This is made possible by fine-grained concrete with low water penetration depth and very small crack widths.

Instituições de ensino superior precisam identificar e analisar o perfil de seus alunos e egressos, para tornar o ensino mais eficiente e evitar evasão. Assim, o objetivo deste estudo foi caracterizar o perfil de alunos e egressos do curso de Ciência da Computação, investigando padrões de interesses profissionais dos alunos e o contexto de trabalho de egressos e de alunos, que atuam na área de computação. Combinamos duas estratégias para caracterizar estudantes e egressos de computação: coleta de dados do tipo survey e acompanhamento automatizado de egressos por meio do sistema desenvolvido por Alvares et al. (2020). Participaram da survey 74 pessoas, envolvendo graduandos (n = 56) e egressos (n = 18). Por meio da coleta automatizada, conseguimos dados dos 61 alunos que concluíram a graduação em computação. Verificamos que o perfil da amostra é caracterizado por homens pardos com idade média de 23 anos, realizando a primeira graduação. Houve coincidência entre a subárea da computação pela qual os estudantes possuem maior interesse e que a maioria dos egressos atuam profissionalmente: engenharia e desenvolvimento de software. Verificamos, ainda, que a maioria dos graduados está empregada, atuando na sua área de formação e satisfeitos com o seu trabalho. Esperamos que estudos futuros possam aperfeiçoar as estratégias de pesquisa e ampliar os dados disponíveis sobre perfis de estudantes e egressos de cursos de computação.

O Brasil é grande consumidor de agrotóxicos para manter alta produção das culturas agrícolas combatendo pragas, doenças e plantas daninhas. Quando há manejo errado ocorrem implicações no meio ambiente e saúde humana. Diante disto, o objetivo do estudo foi avaliar o perfil do agricultor quanto ao uso de agrotóxicos. Foram realizadas entrevistas semiestruturadas com 140 agricultores do Agreste Alagoano, no ano de 2019. 49,28% não concluíram o ensino fundamental e 20,76% não sabem ler. Foi constatado que 81,44% usam agrotóxicos e dos 32 tipos citados, 83,13% são inadequados às culturas, 34,37% são extremamente tóxicos à saúde humana e 78,12% são muito perigosos ao meio ambiente. Quanto aos Equipamentos de Proteção Individual, 45,71% não usam no momento da preparação e 37,85% não usam no momento da aplicação dos agrotóxicos, com o uso de forma incompleta. Apenas 5,71% fazem a tríplice lavagem e 40% queimam as embalagens após o uso. Os principais sintomas percebidos por agricultores durante ou após o uso dos agrotóxicos foram alterações na visão (48,5%), nervosismo, tensão e preocupação (48,5%) e tonturas (32,8%). De forma geral, as várias ações inadequadas de manejo dos agrotóxicos podem estar relacionadas à baixa escolaridade dos agricultores o que leva a riscos ao ambiente e à saúde.

Digestive dynamics: Unveiling interplay between the gut microbiota and the liver in macronutrient metabolism and hepatic metabolic health
Authors: Kandalgaonkar Mrunmayee R. , Kumar Virender , Vijay‐Kumar Matam
Published: June 2024

Although the liver is the largest metabolic organ in the body, it is not alone in functionality and is assisted by “an organ inside an organ,” the gut microbiota. This review attempts to shed light on the partnership between the liver and the gut microbiota in the metabolism of macronutrients (i.e., proteins, carbohydrates, and lipids). All nutrients absorbed by the small intestines are delivered to the liver for further metabolism. Undigested food that enters the colon is metabolized further by the gut microbiota that produces secondary metabolites, which are absorbed into portal circulation and reach the liver. These microbiota‐derived metabolites and co‐metabolites include ammonia, hydrogen sulfide, short‐chain fatty acids, secondary bile acids, and trimethylamine N‐oxide. Further, the liver produces several compounds, such as bile acids that can alter the gut microbial composition, which can in turn influence liver health. This review focuses on the metabolism of these microbiota metabolites and their influence on host physiology. Furthermore, the review briefly delineates the effect of the portosystemic shunt on the gut microbiota–liver axis, and current understanding of the treatments to target the gut microbiota–liver axis.

Published: June 2024

A pot experiment was conducted to investigate the combined effects of different nitrogen fertilizer levels (5, 25, and 45 kg of pure nitrogen per 667 m²) and biochar concentrations (0, 0.7, 1.4, and 2.1%) on the growth, yield, and fruit quality of pepper. The findings indicated that a combination of 25 kg/667 m2of nitrogen and either 0.7% or 1.4% biochar significantly enhanced plant growth, yield, and fruit quality. Specifically, the N2 treatment (25 kg of pure nitrogen per 667 m²) increased substrate porosity, alkali-hydrolyzed nitrogen content, and available phosphorus content. It also boosted root activity and superoxide dismutase activity in pepper leaves, resulting in increased yield and better fruit quality. Furthermore, the proper addition of biochar (0.7–1.4% by weight) enhanced the physical and chemical properties of the substrate, including increased chlorophyll content and enzyme activity in plants, thereby leading to improved overall plant growth, yield, and fruit quality.

Published: June 2024

Ethnobotanical studies revealed the experience and knowledge of people who learned the therapeutic virtues of plants through trials and errors and transferred their knowledge to the next generations. This study determined the ethnobotanical use ofJuniperus drupacea(Andiz) in the Antalya province and the current and future potential distribution areas ofJ. drupaceain Türkiye during 2041–2060 and 2081–2100 according to the SSP2-4.5 and SSP5-8.5 scenarios and based on the IPSL-CM6A-LR climate change model. The very suitable areas encompassed 22379.7 km2. However, when the SSP2-4.5 scenario was considered, the areas most suitable forJ. drupaceacomprised 6215.892 km2for 2041–2060 and 378.318 km2for 2081–2100. Based on the SSP5-8.5 scenario, the area most suitable forJ. drupaceawas 979.082 km2for 2041–2060. However, no suitable areas were identified with the SSP5-8.5 scenario for 2081–2100. Considering the models for the future estimated distribution areas ofJ. drupacea, serious contractions endangering the species are predicted in its distribution areas. Therefore, scientific research should focus on identifyingJ. drupaceapopulations and genotypes that demonstrate resilience to future drought conditions resulting from climate change. This endeavor is crucial as it holds significant ecological and economic values.

The anticipated antenna is systematically examined within the ultra-wideband (UWB) range from 3.1 GHz to 10.6 GHz design frequency with four different steps: Antenna 1, Antenna 2, Antenna 3 and Antenna 4 (optimal design) are chosen for comprehensive study. A unique isolation structure was developed between two identical elements separated by 10 mm, resulting in an enhanced isolation of −23.5 dB at 3.15 GHz, −27 dB at 5.8 GHz, −28 dB at 9.26 GHz and greater than −34 dB at 7.5 GHz. The suggested antenna resonates at UWB band and have fractional bandwidth of 118.66 % and a peak gain of 4.1 dB at 3.15 GHz, 3.68 dB at 5.8 GHz, 6.4 dB at 7.5 GHz and 3.2 dB at 9.26 GHz has been obtained. Radiation efficiencies of 92.5 %, 95 %, 90 % and 84.5 % at 3.15 GHz, 5.8 GHz, 7.5 GHz and 9.26 GHz were obtained respectively. The recommended MIMO performance is simulated using HFSS in terms of ECC, DG, MEG and CCL. The results adhere to specified requirements and confirmed by experimentation. An HFSS simulated dataset of reflection coefficient is used as input for the various ML algorithms namely, Support Vector Machine (SVM), Ensemble, k-nearest neighbors’ algorithm (KNN) and Gaussian Process Regression (GPR) models are trained with 80 % of the data and testing with 20 % of the data.

Published: June 2024

This study introduces a cutting-edge Matrix Pencil-based Dual Grid Energy Management System (MP-DEMS) aimed at seamlessly integrating electric vehicles (EVs) into power grids while enhancing power quality (PQ) and reliability (PR). Operating within an AC-DC hybrid microgrid (HMG) framework, the MP-DEMS reduces the necessity for additional conversion devices, simplifying the integration of EVs and batteries. The core of the proposed DEMS comprises three key modules: the Wind Energy Management Module (WEMS), Smart Storage and EV Power Coordination (SS-EVPC), and Coordinated Power Conversion Control (CPCC). These modules work together to optimize energy usage, leverage renewable sources effectively, and manage EV charging/discharging schedules to minimize grid impact. An innovative aspect of the MP-DEMS is its use of Matrix Pencil-based techniques, offering several advantages over traditional Discrete Fourier Transform (DFT) methods. These advantages include swift dynamic response, resilience to voltage variations, and precise voltage phase estimation. Software simulations and Hardware-in-the-Loop (HIL-402) testing validate the efficacy of the MP-DEMS approach, showcasing enhanced power transfer capabilities, improved harmonic performance, and superior voltage/frequency regulation within EV-HMS applications. Overall, the MP-DEMS presents a promising solution for advancing the integration of EVs into microgrid systems, contributing to a more sustainable and reliable energy future.

Objective

The present study was aimed at investigating the antinociceptive and anti-inflammatory activities of the solvent fractions of the roots of Echinops kebericho Mesfin in rodent models of pain and inflammation.

Methods

Successive maceration was used as a method of extraction using solvents of increasing polarity: methanol and water. Ethyl acetate, chloroform and distilled water were used as solvents of the fraction process. Swiss albino mice models were used in acetic acid induced writhing, hot plate, carrageenan induced paw edema and cotton pellet granuloma to assess the analgesic and anti-inflammatory activities. The test groups received different doses (100 mg/kg, 200 mg/kg and 400 mg/kg) of the three fractions (chloroform, ethyl acetate and aqueous). The positive control groups received ASA (150 mg/kg) for the writing test, morphine (10 mg/kg) for the hot plate method, diclofenac Na for carrageenan-induced paw edema, and dexamethasone (10 mg/kg) for granuloma, while the negative control group received distilled water.

Results

EA fraction at all test doses employed (100 mg/kg, 200 mg/kg, and 400 mg/kg) showed statistically significant (p<0.05, p<0.01, p<0.001 respectively) analgesic and anti-inflammatory activities in a dose-dependent manner. The AQ fraction on the other hand produced statistically significant (p<0.05, p<0.012) analgesic and anti-inflammatory activities at the doses of 200 mg/kg and 400 mg/kg, while the CH fraction exhibited statistically significant (p<0.05) analgesic and anti-inflammatory activity at the dose of 400 mg/kg.

Conclusions

In general, the data obtained from the present study elucidated that the solvent fractions of the study plant possessed significant analgesic and anti-inflammatory activities and were recommended for further investigations.
Thermoeconomic optimization with a dissipation cost
Authors: Ares de Parga-Regalado Angela M. , Ares de Parga Gonzalo
Published: June 2024

From a finite-time thermodynamics perspective, a thermoeconomic analysis of a Novikov model employing a linear heat transfer law is carried out. A new component in the cost function is proposed to examine its relationship with waste management while operating in the maximum power, ecological, and efficient power regimes. The methodology consists of optimizing the profit function by including our new waste management cost function, leveraging the same method used by DeVos (“Endoreversible thermoeconomics,” Energy Convers. Manage., vol. 36, pp. 1–5, 1995) and Pacheco et al. (“Thermoeconomic optimization of an irreversible novikov plant model under different regimes of performance,” Entropy, vol. 19, p. 118, 2017). Searching for the optimal thermoeconomic efficiencies for the ecological case a novel numerical method developed by the corresponding author (A. M. Ares de Parga-Regalado, “Analytical approximation of optimal thermoeconomic efficiencies for a novikov engine with a Stefan–Boltzmann heat transfer law,” Results Phys., 2023) is used. Analytical expressions for the optimal efficiencies are obtained, and the impact of the proposed term on these values is investigated.
Topological valley-locked waveguides with C4 impurity

Published: June 2024

Heterostructures play a pivotal role in the design of valley-locked waveguides, facilitating the manipulation of width as an additional degree of freedom. Through this design, we demonstrate the extension of the topological guided modes from the domain wall of topologically nontrivial valley photonic crystals (VPCs) into the trivial VPCs. We propose a C4 impurity to control the states of the light wave transmission in topological valley-locked waveguides through the intervalley scattering of defects in Quantum Valley Spin Hall topological insulators. By rotating the C4 structure, the ON/OFF (0°/45°) state of the valley-locked waveguides can be controlled, effectively serving as a switch component. Furthermore, many unique applications could be devised based on the introduced impurity. Examples include the development of coding channels with arbitrary output ports and energy concentrators with enhanced secondary concentration. The proposed topological valley-locked waveguides with C4 impurity will be beneficial for on-chip integrated photonic networks.

Modifications and applications of aerogel prepared with waste palm leaf cellulose in adsorptions for oily contaminations

Published: June 2024

Aerogels are essential and effective materials for oily pollution adsorption and recovery. This work described a hydrophobic modified cellulose aerogel using waste palm leaf and its oil adsorption mechanism. By chemical vapor deposition, Methyltrimethoxysilane (MTMS) was employed as a hydrophobic modifier for aerogel of waste palm leaf cellulose at 80 °C for 5 h, and the modified aerogel demonstrated exceptional and stable hydrophobicity with a water contact angle of 132.4° that can still be maintained above 120° after two months of air exposure. After 10 adsorption and extrusion cycles, kerosene adsorption capacity can still reach over 18 times its weight with good regeneration and reuse performance. The kinetic analysis found that the pseudo-second order model was more appropriate for the aerogel’s oil absorption process, including mainly physical adsorption at the beginning and the following chemical adsorption. Owing to its low cost, hydrophobicity, high absorption capacity, and favorable reusability, this aerogel is expected to be used in oils, organic solvent spill cleanup, and oil/water separation fields.
