A Mini Review on the Application of Chitosan Composites for the
Adsorption of Fluoride from Aqueous Solution
Authors: Sutherland Clint , Chittoo Beverly , Islam Abdel
Published: July 2023

Background:

Exploration into the development of cost-effective and eco-friendly adsor-bents for the removal of fluoride continues to be unabated. The modification of chitosan through the development of composites and derivatives has shown great promise over the past decade. These modifications aim to overcome the limitation of chitosan, such as separability and adsorption capacity.

Objectives:

The objective of this study is to review various modifications to chitosan for defluorida-tion, the resulting adsorption capacities, operational parameters that appreciably influence the full-scale application of adsorption systems and, where reported, the mechanisms that influenced the ad-sorption process.

Results and Discussion:

Among the adsorbents reviewed, most of the processes were best modelled by the Langmuir isotherm and the pseudo-second order model. Chitosan composites were able to achieve significantly higher F- adsorption capacities and compared well to other adsorbents in the literature. Gamma degraded chitosan-Fe(III) beads, 10%-Lanthanum-incorporated chitosan beads and neodymium-modified chitosan were found to easily achieve the WHO drinking water limit of 1.5 mg/L. In all instances, the reactions were spontaneous and endothermic. Fluoride adsorption was shown to increase from the acidic region to near neutral pH followed by a decrease into the al-kaline range.

Conclusion:

The presence of competing ions is a major operational parameter for full-scale adsorp-tion applications. The presence of carbonate and bicarbonate ions has been a consistent hindrance in reported studies. Thus, future investigations are warranted in this area.
The Potential of Plant-based Composite Material for Regenerative Medicine
Authors: Wan Kamarul Zaman Wan Safwani
Published: July 2023

Regenerative medicine focuses on replacing injured tissues and organs by
utilising biophysical and biochemical cues to develop bioscaffolds suitable for
regenerating damaged or injured tissues. The scaffold has an important role in guiding
the development of the regenerative process that allows the migration and attachment
of cells and, to a certain extent, becomes the source of nutrients influencing the cells or
tissue's biological mechanism. Hence, the selection of biomaterials is important to
ensure biocompatibility and suitable mechanical properties for tissue engineering.
Different sources and types of biomaterials can be used in the fabrication of scaffolds,
including composites. Composite biomaterials consist of more than one material with
different morphologies and compositions, causing it to become multiphased, which can
ameliorate the scaffold’s mechanical properties, flexibility, and structural properties to
ensure a suitable microenvironment for cell growth and viability. Nevertheless,
biocompatibility issues need to be addressed, particularly with synthetic materials,
which led investigators to explore other sources and types, such as plant-based
biomaterials, to fabricate suitable and safer composites. Aside from being more
sustainable and perhaps more eco-friendly, plant-based composite materials fulfill the
criteria required for biomaterials and exhibit many advantages that can be adapted in
their fabrication techniques. Hence, in this chapter, the advantages and development of
plant-based materials will be discussed, focusing on the potential of oil palm and
konjac plants as sources of biomaterials

Authors: Mh Busra Mohd Fauzi , Mazlan Zawani , Masri Syafira , Smandri Ali
Published: July 2023

Tissue replacement using engrafting biomaterials or artificial organs to
restore lost functions post-injury is one of the leading regenerative medicine practices.
The last two decades witnessed the emergence of many promising biofabrication
approaches such as bioprinting. However, bioprinting allows the placement of complex
structures that are multi-layer (using hydrogel biomaterials), multicellular,
vascularized, and multifunctional. Different bioprinting approaches are being
developed and used to print hundreds of promising bioinks combinations into tissue-specific niches to grow living organs for translation, disease modelling, and drug
delivery. This book chapter reviews the three primary bioprinting techniques with their
advantages and limitations. Moreover, this chapter discusses the natural and synthetic
biomaterials and the additives and crosslinking methods used to fabricate functional
bioinks that boost cell growth, proliferation, migration, differentiation, and
homeostasis.
Oral Autobiography: A New Paradigm for Identification
Authors: Ashok Gawali Rohan , Mishra Shaivya
Published: July 2023

Identity is central to an individual’s personality and his/her existence. The
face is synonymous with identity. Identity needs to be proven in daily life transactions
for security reasons. Identity (be it of the victim or the suspect) is also a paramount
investigative question for which the answer is not straightforward. The orofacial region
is packed with individualistic information ready to be explored in different areas, such
as disasters, crimes, civil matters, and access to property (biometrics). The orofacial
structures offer diverse solutions to the common questions of identity. The choice of a
specific technique is governed by the circumstances that call for identification and the
advantages-disadvantages of the technique.
Diffraction mathematical model of a laser speckle interferometer of transverse displacements of a scattering object
Authors: Maksimova L.A.  , Mysina N.Y.  , Patrushev B.A.  , Ryabukho V.P.
Published: July 2023

On the basis of diffraction transformations of wave fields, a mathematical model of a speckle interferometer of transverse displacements of a scattering object has been developed and numerical modeling of speckle-modulated interference patterns and signals at the output of the interferometer has been performed. Numerical calculations of the spatial distribution of complex amplitudes of wave fields in an interferometer were used for modeling when the displaced scattering surface was illuminated by two obliquely incident laser Gaussian beams. A statistical numerical experiment was performed to determine the measurement error of the scattering surface displacement caused by the change of realizations of interfering speckle fields. The simulation results are in good agreement with the results of experimental studies of transverse displacements in the range up to 600 micrometers. Keywords: interferometry, diffraction, interference, laser interferometer, speckle interferometry, interference pattern, speckle modulation, computer simulation.

Published: July 2023

The a-SiOxNy : H films of various compositions were obtained by plasma chemical deposition from a gas mixture of 10% monosilane (diluted with argon) and nitrogen in the presence of residual oxygen in the working gas mixture. The nitrogen flow rate varied in the range from 4 to 6 cm3/min, the power of the high-frequency generator (13.56 MHz) varied in the range of 50-150 Watts. The electronic structure and optical properties of the films were studied using X-ray photoelectron spectroscopy, vibrational spectroscopy, transmission and reflection spectroscopy, and spectral ellipsometry. It is shown that, as the generator power decreases, the content of excess silicon in the films increases and amorphous silicon nanoclusters appear. As the generator power increases, the oxygen concentration in the films decreases. Apparently, this is due to the greater dissociation of molecular nitrogen with an increase in the power of the plasma discharge and an increase in the concentration of active nitrogen. Thus, it is possible to control the composition of aa-SiOxNy : H films not only by changing the nitrogen flow, but also by varying the generator power. Keywords: silicon oxynitride, plasma-chemical deposition, stoichiometric composition, Si nanoclusters.

Published: July 2023

Dynamic control of chaotic dark dissipative envelope solitons in a microwave active ring resona tor containing two nonlinear elements: a one-dimensional magnonic crystal (MC) with a dynamic linear defect and a transistor amplifier is performed. Dissipative envelope solitons are formed on a long-wavelength surface magnetostatic wave propagating in the MC and parametrically decaying into short-wavelength spin waves. A constant electric current flowing through a copper conductor creates a dynamic linear defect along the longitudinal axis of the MC and controls the duty factor of the generated parametric pulses only at the MC forbidden frequency. Keywords: dissipative solitons, magnonic crystals, spin waves.
Development and Testing of a Mobile App to Collect Social Determinants of Health Data in Cancer Settings: Interview Study
Authors: Oyedele Natasha K , Lansey Dina G , Chiew Calvin , Chan Cupid , Quon Harry , Dean Lorraine T
Published: July 2023

Background

Social determinants of health (SDOH) such as lack of basic resources, housing, transportation, and social isolation play an important role for patients on the cancer care continuum. Health systems’ current technological solutions for identifying and managing patients’ SDOH data largely focus on information recorded in the electronic health record by providers, which is often inaccessible to patients to contribute to or modify.

Objective

We developed and tested a patient-centric SDOH screening tool designed for use on patients’ personal mobile phone that preserves patient privacy and confidentiality, collects information about the unmet social needs of patients with cancer, and communicates them to the provider.

Methods

We interviewed 22 patients with cancer, oncologists, and social workers associated with a US-based comprehensive cancer center to better understand how patients’ SDOH information is collected and reported. After triangulating data obtained from thematic analysis of interviews, an environmental scan, and a literature search of validated tools to collect SDOH data, we developed an SDOH screening tool mobile app and conducted a pilot study of 16 dyadic pairs of patients and cancer care team members at the same cancer center. We collected patient SDOH data using 36 survey items covering 7 SDOH domains and used validated scales and follow-up interviews to assess the app’s usability and acceptability among patients and cancer care team members.

Results

Formative interviews with patients and care team members revealed that transportation, financial challenges, food insecurity, and low health literacy were common SDOH challenges and that a mobile app that collected those data, shared those data with care team members, and offered supportive resources could be useful and valuable. In the pilot study, 25% (4/16) of app-using patients reported having at least one of the abovementioned social needs; the most common social need was social isolation (7/16, 44%). Patients rated the mobile app as easy to use, accurately capturing their SDOH, and preserving their privacy but suggested that the app could be more helpful by connecting patients to actual resources. Providers reported high acceptability and usability of the app.

Conclusions

Use of a brief, patient-centric, mobile app–based SDOH screening tool can effectively capture SDOH of patients with cancer for care team members in a way that preserves patient privacy and that is acceptable and usable for patients and care team members. However, only collecting SDOH information is not sufficient; usefulness can be increased by connecting patients directly to resources to address their unmet social needs.
Supporting Children’s Social Connection and Well-Being in School-Age Care: Mixed Methods Evaluation of the Connect, Promote, and Protect Program (Preprint)
Authors: Milton Alyssa Clare , Mengesha Zelalem , Ballesteros Kristin , McClean Tom , Hartog Saskia , Bray-Rudkin Lucie , Ngo Cathy , Hickie Ian
Published: July 2023

BACKGROUND

School-age care, such as outside school hours care (OSHC), is the fastest-growing childhood education sector in Australia. OSHC provides a unique opportunity to deliver programs to enhance primary school–age children’s social, emotional, physical, and cognitive well-being.

OBJECTIVE

This study aimed to pilot the co-designed Connect, Promote, and Protect Program (CP3) and conduct formative and process evaluations on how well the CP3 achieved its intended aims, ascertain areas for improvement, and determine how the CP3 model could be better sustained and extended into OSHC settings.

METHODS

A naturalistic formative and process evaluation of the CP3 implementation was undertaken at 1 and then 5 OSHC sites. Qualitative and quantitative feedback from stakeholders (eg, children, OSHC educators, volunteers, and families) was collected and incorporated iteratively for program improvement.

RESULTS

The formative and process evaluations demonstrated high program engagement, appropriateness, and acceptability. Co-design with children was viewed as highly acceptable and empowered children to be part of the decision-making in OSHC. Feedback highlighted how the CP3 supported children in the 4 CP3 domains: Build Well-being and Resilience, Broaden Horizons, Inspire and Engage, and Connect Communities. Qualitative reports suggested that children’s well-being and resilience were indirectly supported through the Broaden Horizons, Inspire and Engage, and Connect Communities CP3 principles. Matched-sample 2-tailed t tests found that children’s prosocial behaviors increased (mean difference=0.64; P=.04; t57=−2.06, 95% CI −1.36 to −0.02) and peer problems decreased (mean difference=−0.69; P=.01; t57=2.57, 95% CI 0.14-1.13) after participating in the CP3. Program feasibility was high but dependent on additional resources and CP3 coordinator support.

CONCLUSIONS

To our knowledge, the CP3 is the first co-designed well-being program developed and evaluated specifically for OSHC services. This early evidence is promising. The CP3 may provide a unique opportunity to respond to the voices of children in OSHC and those that support them through creative and engaging co-designed activities. Our research suggests that CP3 provides OSHC with a framework and high-quality program planning tool that promotes tailored interventions developed based on the unique needs and preferences of those who will use them.
The effect of COVID-19 on patients with liver cirrhosis: A systematic review and meta-analysis of retrospective studies (Preprint)
Authors: Wei Qiaoxin , Chen Sisi , Wei Linlin , Zhang Xiangying , Liu Mei , Ren Feng
Published: July 2023

BACKGROUND

Coronavirus disease 2019 (COVID-19) is long-lasting and has an adverse effect on liver function. However, the impact of COVID-19 on the outcome of patients with liver cirrhosis has not been consistently clear.

OBJECTIVE

We aimed to conduct a systematic review and meta-analysis to explore whether COVID-19 negatively impacts cirrhosis patients.

METHODS

We conducted a systematic search of the PubMed/Medline, Embase, and Cochrane Library databases to compare cirrhosis patients with and without COVID-19. Two authors independently performed data extraction and quality evaluation using the Newcastle‒Ottawa Scale. Data pooling was conducted using random-effects or fixed-effects models based on the heterogeneity of the included studies.

RESULTS

A total of 13 studies were included that involved 949 patients with cirrhosis and COVID-19 and 15,196 patients with cirrhosis only. Of the 13 studies, ten were studies among hospitalized patients, and three were studies among discharged patients. COVID-19 infection increased the mortality, ICU (Intensive Care Unit) admission rate, length of hospital stay and incidence of acute-on-chronic liver failure (ACLF), Child‒Pugh C and hepatic encephalopathy among hospitalized patients with liver cirrhosis. However, COVID-19 infection did not affect the mortality rate or the incidence of Child‒Pugh C among patients with cirrhosis after discharge.

CONCLUSIONS

In hospitalized patients with cirrhosis, infection with COVID-19 may be a potential risk factor for adverse clinical outcomes. However, COVID-19 infection seems to have no effect on patients with cirrhosis after discharge. It is recommended that clinicians pay more attention to the prevention and treatment of COVID-19 in patients with preexisting liver cirrhosis.

Mahalanobis Fuzzy C-Means Clustering with Spatial Information for Image Segmentation
Authors: Gunawan Wawan , Latifah Nurul
Published: July 2023

A fuzzy C-Means segmentation algorithm can be implemented in an image segmentationbased on the Mahalanobis distance; However, this method only needs to consider the colorspace situation, not the neighborhood system of the image. It was an effective edge detectionprocess unwell performed and generated less accuracy in segmentation results. In this article,we propose a new method for image segmentation with Mahalanobis fuzzy C-means Spatialinformation (MFCMS). The proposed method combines feature space and images of theinformation of the neighborhood (spatial information) to improve the accuracy of the result ofsegmentation on the image. The MFCMS consists of two steps, the histogram threshold modulefor the first step and the MFCMS module for the second step. The Histogram Threshold moduleis used to get the MFCMS initialization conditions for the cluster centroid and the number ofcentroids. Test results show that this method provides better segmentation performance thanclassification errors (ME) and relative foreground area errors (RAE) of 1.61 and 3.48,respectively.

Authors: Abuhmida Mabrouka
Published: July 2023

The article discusses how impact actions, such as conflict and warfare, can negatively impact the structural integrity of concrete structures and how detecting hidden defects in concrete structures is difficult without expert knowledge. The paper presents a new technique that combines thermal imaging and artificial intelligence to detect hidden defects in concrete structures. The authors trained an AI model on simulated data and achieved a validation accuracy of 99.93%. They then conducted a laboratory experiment to create a dataset of concrete blocks with and without subsurface cracks and trained a new model, which achieved a validation accuracy of 100%. The article concludes that AI can detect hidden defects and subsurface cracks in concrete structures by classifying thermal images of concrete surfaces.
An Experimental Study on Societal Factors Affecting VOT of English Plosives
Authors: Xiaoyan Lin
Published: July 2023

Plosives are integral components of English consonants. In phonetics, English plosives are classified into voiceless plosives /p, t, k/ and /b, d, g/. VOT (voice onset time) was defined as “the time interval between the burst that marks release of the stop closure and the onset of quasi-periodicity that reflects laryngeal vibration”. VOT is a significant acoustic feature and analytic parameter of plosives. Referring to Labov’s experimental model of linguistic variation analysis, this study investigates the influences of societal factors have on the VOT of English plosives.In this study, 15 English words with word-initial voiceless plosives /p, t, k/ and 15 word-initial voiced plosives /b, d, g/ were selected as reading material; meanwhile, 30 subjects were randomly recruited to read, and audio samples were collected. It is found that the two social factors (gender and regional dialect) selected in this experiment have influences in different degrees on the English plosive VOT of the subjects. The specific results are as follows.For gender, no significant difference exists between males and females, but the mean VOT of females is longer than that of males, which is basically consistent with previous research results. The underlying reasons of the gender VOT differences inferred by this paper can be physiological and sociophonetical. For regional dialects, the VOT of the subjects were primarily influenced by Southwest Mandarin and Min Dialect, in which the mean value of voiceless plosives was higher and the difference was greater for speakers of Southwest Mandarin, and the mean value of voiced plosives was higher and the difference was greater for speakers of Min Dialect. The results of this empirical study theoretically provide some reference for acoustic researches, and pedagogically, provide some implications for optimizations of English curriculums in university.
La crítica a la escuela tradicional desde la perspectiva de la educación emocional
Authors: Abramowski Ana Laura , Sorondo Juana
Published: July 2023

Este artículo busca problematizar la actual expansión de la educación emocional (EE) en las escuelas, complementando la lectura crítica que señala sus vínculos con la racionalidad neoliberal. Se parte de hallazgos de una investigación cualitativa exploratoria sobre el ingreso de la EE en escuelas secundarias del Área Metropolitana de Buenos Aires, Argentina, que ponen de relieve que esta propuesta legitimaría su implementación al apelar a una crítica a la escuela tradicional. Se interroga, por consiguiente, la configuración histórica de los discursos críticos-educativos que dieron lugar a la categoría de la "escuela tradicional", para comprender su reapropiación por parte de la EE. Este análisis también pone en evidencia que la EE, lejos de ser un enfoque novedoso, refuerza patrones conservadores sedimentados en el campo educativo. Se discute, asimismo, la lectura sobre la fagocitación neoliberal del discurso de la crítica educativa, para concluir sobre la necesidad de una "crítica de la crítica".
Lift and Drag Analysis of NACA 1412 Airfoil Using Unstructured Mesh
Authors: Thorwat Sanket
Published: July 2023

Abstract: This research paper gives insight to the analysis of NACA 1412 airfoil. The airfoil is the two-dimensional cross section of the aircraft’s wing. The aircraft flies due to generation of the lift, this lift is caused by the pressure difference on the upper and lower surface of the airfoil. The pressure on the lower surface is greater than the pressure on upper surface which provides a lift to the airfoil. We are going to see the airfoil’s behaviour in incompressible flow at different angles of attack with constant velocity. In this research, we are going to use the Ansys software to do the analysis. This research is based on the computational fluid dynamics concepts. At the end, we will see how the lift and drag changes at different angles of attack and some graphical results from the research.
Distress Investing: An Analysis of Strategies and Risk-Reward Dynamics
Authors: Jaiswal Dr. Vikas Kumar
Published: July 2023

Abstract: Distress investing is a specialized investment strategy that involves capitalizing on undervalued distressed assets with the anticipation of future recovery. This paper explores the historical background, evolution, and key principles of distress investing, emphasizing its importance in financial markets, especially during economic downturns. The literature review presents a comprehensive overview of distress investing research, summarizing key themes and research areas. It reviews seminal works and early studies related to distress investing, examining strategies such as distressed debt, equity, and turnaround investing. The role of macroeconomic and industry-specific factors in influencing distress investing opportunities is explored, along with valuation techniques for distressed assets and the impact of corporate governance. The research methodology outlines the objectives of the study and the data collection process, using financial databases, company reports, and academic journals. Criteria for sample selection and key variables used to evaluate distress investing strategies are identified, along with the analytical approach employed. The potential limitations of the research methodology are also acknowledged.
Well-conditioned multi-product formulas for hardware-friendly Hamiltonian simulation
Authors: Carrera Vazquez Almudena , Egger Daniel J. , Ochsner David , Woerner Stefan
Published: July 2023

Simulating the time-evolution of a Hamiltonian is one of the most promising applications of quantum computers. Multi-Product Formulas (MPFs) are well suited to replace standard product formulas since they scale better with respect to time and approximation errors. Hamiltonian simulation with MPFs was first proposed in a fully quantum setting using a linear combination of unitaries. Here, we analyze and demonstrate a hybrid quantum-classical approach to MPFs that classically combines expectation values evaluated with a quantum computer. This has the same approximation bounds as the fully quantum MPFs, but, in contrast, requires no additional qubits, no controlled operations, and is not probabilistic. We show how to design MPFs that do not amplify the hardware and sampling errors, and demonstrate their performance. In particular, we illustrate the potential of our work by theoretically analyzing the benefits when applied to a classically intractable spin-boson model, and by computing the dynamics of the transverse field Ising model using a classical simulator as well as quantum hardware. We observe an error reduction of up to an order of magnitude when compared to a product formula approach by suppressing hardware noise with Pauli Twirling, pulse efficient transpilation, and a novel zero-noise extrapolation based on scaled cross-resonance pulses. The MPF methodology reduces the circuit depth and may therefore represent an important step towards quantum advantage for Hamiltonian simulation on noisy hardware.

Lampung adalah salah satu wilayah yang produksi ladanya dipertahankan karena lada hitam lampung termasuk komoditi yang terbaik. Petani lada diwajibkan untuk menjual produknya kepada pemerintah kolonial melalui kepala-kepala marga. Lada merupakan komoditi wajib untuk ditanam namun dalam skala yang kecil pada masa kebijakan tanam paksa yang diteraqpkan oleh pemerintahan Belanda. Artikel ini bertujuan untuk mengungkap dampak kebijakan tanam paksa di Lampung dan pengaruhnya bagi keadaan sosial serta perdagangan lada pada tahun 1830-1865. Penelitian ini menggunakan metode sejarah yang terdiri dari heuristik, kritik, interpretasi, dan historiografi. Berdasarkan hasil penelitian pada masa pemerintahan Belanda dan saat diterapkannya kebijakan tanam paksa menunjukkan adanya pergolakan dalam tatanan sosial serta ekonominya. Pada masa diterapkannya tanam paksa khususnya di tahun 1830-1865 banyak terjadi perlawanan yang dilakukan oleh masyarakat Lampung. Hal ini dilakukan karena kebijakan tersebut sangat merugikan pihak masyarakat Lampung. Tanam paksa komoditi lada pada masa itu juga mengalami penurunan dikarenakan terdapat komoditi baru yang ditetapkan seperti kopi, tembakau, dan nila yang saat itu sangat diminati pasaran dunia. Sehingga produksi lada dan penjualan lada kian lama semakin menurun.

Penyalahgunaan Ayat Al-Quran dan Hadis oleh Golongan Agnostik dalam Persoalan Akidah
Authors: Talip Farah Hanie , Kamarzaman Mohd Haidhar , Ibrahim Mazlan
Published: July 2023

In recent times, there has been an increasing rejection of faith and indoctrination in religion. Agnostic beliefs are among the ideologies that seek to liberate the human mind from any assumptions about God. What misleads them is when they make objections to the primary sources of reference for the Islamic community, al-Quran and hadith, which ultimately result in misunderstandings in understanding the main sources of Islam. Therefore, the purpose of this article is to study the issues of misuse of Quranic verses and hadith and the distorted interpretations by the agnostic group in matters of faith. This study uses a qualitative research design using document analysis, comparative analysis, and historical analysis approaches. The writings of the agnostic group in mass media such as articles, magazines and newspapers related to the misuse of Quranic verses and hadith in matters of faith are examined and analysed. The findings of the study reveal that the confusion and misunderstandings of the agnostic group regarding Quranic verses and hadith are caused by various factors, including an excessive reliance on logical reasoning, a lack of proper understanding of faith, misconceptions about contextual and textual approaches, and the use of hermeneutical methods in interpreting Quranic verses and hadith.
Exploring Hans Küng’s Paradigm Theory for Understanding Religion: An Islamic Perspective
Authors: Che Nordin Mohd Khairul Naim
Published: July 2023

This article discusses the paradigm theory and its application to understanding religion, with a focus on the perspective of Islam. Hans Küng’s paradigm theory is examined, which involves analyzing religious paradigms and their changes to understand religion comprehensively. The article explains that Küng’s approach involves examining several aspects of religion, such as its history, development, current situation, and predictions or assumptions about its future based on its history and current situation. However, the article also highlights some questions regarding the methodology used by Küng to identify the stages of the paradigm and the shifts that occur. Additionally, the article notes that understanding religion based on paradigm theory is not sufficient to adequately describe the identity of a religion. Overall, this article sheds light on the strengths and limitations of using paradigm theory to understand religion, particularly from an Islamic perspective. Therefore, a nuanced understanding of Islam requires sensitivity to its unique theological and textual contexts.

Published: July 2023

Carbon dots (CDs) are a new member of fluorescent nano carbons that have attracted attention because of their potential applications derived from their optical, chemical, and electrical properties. CDs from jengkol peel via the solvothermal method at 200 oC for 7 h with the addition of ethylenediamine (EDA) as a heteroatom dopant have been successfully carried out. This study aims to determine the effect of concentration EDA on the optical properties of CDs for the possible reason. The results revealed that the CDs solution has fluorescence properties; that bluish-green glow can be observed under ultraviolet radiation (365 nm). The UV - Vis absorption peaks did not depend on the CDs concentration, but the absorbance intensity decreased with increasing EDA concentration. The best fluorescence properties were possessed by 10 % EDA in CDs which produced λex/λem of 370 nm / 518 nm, respectively, with a quantum yield of 42 %. The FTIR spectra of all samples showed that the CDs surface had functional groups such as carboxylic acids, hydroxyl, and amines. The obtained CDs have the potential to be used as heavy metal ion detectors, bioimaging, and antibacterial agents.
