EXTRACTION, CHARACTERIZATION AND IDENTIFICATION OF MICROPLASTICS FROM LANDFILL SOIL (Article)
(Kalpana Corporation, 2025-01) Vinod, Veena; Amritha P.S; Harathi P.B
Recently, landfills have become the major sink of all the microplastic waste and hazardous materials that adhere to their surfaces. Hence, it is of utmost importance to detect and estimate the presence of microplastics in landfills to ascertain the fate and impact of these pollutants on the terrestrial environment. Therefore, in this study, the soil samples were collected from seven points of landfills from three layers, extracted using a standard protocol, examined under a stereomicroscope and identified using ATR-FTIR analysis. The abundance of microplastic was high in layer 1 with 64%. Fragments and fibers were abundant in all three layers. The microplastic of size range 0-1 mm were predominantly found in all the layers. Colours, such as white, transparent and blue, were abundant. In addition, the physico-chemical parameters of the site were also studied.
NON-INVASIVE MEASUREMENT OF SPOILAGE OF PACKED FISH USING HALOCHROMIC SENSOR (Article)
(Emerald Publishing, 2025-02-21) Devarayan, Kesavan; Palanisamy, Yazhiniyan; Mohan, Gangeswar; Theivasigamani, Anand; Kandasamy, Sabariswaran; Sekar, Vimaladevi; Siluvai John, Evon Umesh; Sukumaran, Monikandon; Marimuthu, Ramar; Anjappan, Hema
Purpose: This study aims to develop a pH-functional thin-film sensor for non-invasive measurement of spoilage of packed fish. Design/methodology/approach: At first, polymers of natural origin such as hydroxy(propyl)methyl cellulose, potato dextrose agar and starch alongside a pH sensitive-mixed indicator formulation were used to produce thin film sensor. The developed thin film sensor was tested for monitoring the spoilage of seafood stored at 4°C. Using ultraviolet-visible and Fourier-transform infrared spectroscopy, the halochromic sensor was characterised. In addition, the halochromic response of the thin film was directly correlated to the total volatile base nitrogen emitted by the packaged fish, pH, microbial activity and sensory evaluation. Findings: The results suggested the developed biopolymer-based thin film sensor showed different colours in line with the spoilage of the packed fish, which could be well correlated with the total volatile base nitrogen, microbial activity and sensory evaluation. In addition, the thin film sensors exhibited a high degree of biodegradability. The biopolymers-based thin film halochromic sensor has exhibited excellent biodegradability along with sensitiveness towards the spoilage of the packed fish. Originality/value: In the future, consumers and retailers may prefer seafood containers equipped with such halochromic sensors to determine the degree of food deterioration as a direct indicator of food quality.
RECENT TRENDS IN USE OF PLANT-DERIVED CARBON DOT-BASED FLUORESCENT PROBES FOR HEAVY METAL ION DETECTION AND THEIR BIOLOGICAL APPLICATIONS (Review)
(Elsevier B.V., 2025) Venkatesan, Geetha; Sathiyan, Govindasamy
Plant-derived carbon dots (CDs) have drawn a lot of interest as superior nanomaterials because of their sustainable nature, biocompatibility, and environmentally friendly synthesis, which sets them apart from other CDs made from non-renewable resources. The synthesis of CDs from natural sources such as fruits, leaves, bark, stem, flower, seed and biowaste by hydrothermal, pyrolysis, and microwave-assisted method have been investigated to modify the size and features of CDs. The plant-derived CDs exhibit greater sensitivity and selectivity, and their high photoluminescent properties makes it possible to detect physiological and ecological significant metal ions like iron (Fe³⁺), copper (Cu²⁺), lead (Pb²⁺), and mercury (Hg²⁺). This study focuses mainly on crucial elements such as absorption, emission, sensitivity, selectivity, and limits of detection of metal ions, a thorough examination of their sensing characteristics is provided. This review article comprehensively summarizes plant-based CDs with different synthesis methods, characterization techniques, metal ion sensing and its mechanism, stability and biological imaging of CDs. Additionally, we discussed the plant derived CDs for the detection of pesticides and drugs. These CDs also find extensive applications in environmental remediation by offering a sustainable alternative for detecting harmful pollutants. Beyond these sensing, their biological uses of plant-derived CDs, such as bioimaging, antioxidant activity, and therapeutic potential, are finally addressed. This review emphasizes the bright future of plant-derived CDs in biomedicine and sustainable nanotechnology, with a focus on their biological applications and improved sensing capabilities in research development
THE FRINGE BENEFIT OF INDUSTRY 4.0 AND INDUSTRY 5.0 ON THE EDUCATIONAL SECTOR: A COMPREHENSIVE BIBLIOMETRIC REVIEW (Book Chapter)
(IGI Global, 2025-01-31) Vijay, Vihas; Lakshmi, J. Divya
This chapter presents a bibliometric analysis of literature published between 2012 and 2024, exploring the impact of Industry 4.0 and Industry 5.0 technologies on education. Using a dataset of 3281 Scopus-indexed records, the study identifies trends, research patterns, key contributions, and popular keywords. Bibliometric tools like Biblioshiny reveal global research trends, significant studies, and collaboration networks. The analysis highlights the influence of artificial intelligence, the Internet of Things, and robotics on education, particularly during the COVID-19 pandemic, emphasizing scenario-based learning and strategic human resource management. By examining the top 10 contributing papers, this study provides insights for policymakers, educators, and researchers, stressing the need for multidisciplinary research, global collaboration, and longitudinal studies to harness the educational potential of these technological advancements.
CORRECTION TO: INTEGRATING SOLID STEM AND MULTIPLE DISEASE RESISTANCE FOR DEVELOPING CLIMATE-RESILIENT WHEAT (TRITICUM AESTIVUM L.) (Erratum)
(Akademiai Kiado ZRt, 2023-01-23) Shajitha P.; Nisha R; Sivasamy M; Jayaprakash P; Vikas V.K; Gajalakshmi K; Mallick, Niharikha; Babu, Prashanth; Yadav, Rajbir; Vijaishree S; Akileshwaran K.; Peter, John
In this article there is a misrepresentation of rainfall data in the Materials and Methods section under the Study Location and Plant Materials subsection. The original text inaccurately attributes higher rainfall during the winter season to the southwest monsoon. The corrected text, which aligns with regional meteorological data, is shown below. Original Text (3rd to 5th sentences in the subsection): The summer months, particularly from June to October, experience significantly higher rainfall due to the southwest monsoon, contributing approximately 1000–1200 mm to the region’s total annual precipitation. The winter (Rabi) months (November to April) generally have reduced rainfall, averaging around 200–400 mm. This lower precipitation is often attributed to occasional western disturbances, resulting in more stable weather patterns during the winter season. Corrected Text: During the winter season (Rabi, November to March), the northeast monsoon contributes the majority of the annual rainfall, averaging 1000–1200 mm. Despite this higher rainfall, crops are typically in the active tillering stage, which benefits from consistent soil moisture. Conversely, during the summer season (Kharif, June to September), the southwest monsoon contributes a lesser amount of 200–400 mm, but the number of rainy days is significantly higher. This continuous precipitation ensures sustained soil moisture and creates persistently humid conditions, impacting crop growth. This correction is essential as the rainfall data plays a critical role in understanding the environmental factors influencing crop resilience and growth patterns, which is a key focus of our study. In addition to this error, there were minor errors in the captions to Figs. 3 and 4 in that the terms Sr36/Pm6 and Lr19/Sr25, resp., were inadvertently included twice. The original article has been corrected.
