A Review of Lightweight IoT Authentication Protocols From the Perspective of Security Requirements, Computation, Communication, and Hardware Costs
No full textThe Internet of Things (IoT) is a broad area that encompasses various use cases. Numerous use cases include various IoT devices, which necessitate various cryptographic methods to provide distinct security requirements. Due to their limited resources, most IoT devices require lightweight cryptographic implementations. The requirements of use cases must be revealed to use cryptography effectively. Therefore, classifying the security requirements for these scenarios is beneficial when blueprinting a new system design. Authentication is the first level of security and is crucial for ensuring the secure exchange of information. Designing an IoT authentication protocol requires addressing both security requirements and physical constraints. This paper reviews and classifies the studies in IoT authentication published in the last decade. The studies are categorized into two main categories: the authentication factors and commonly preferred cryptographic primitives. Authentication factors include passwords, RFID, smart cards, and OTPs, while cryptographic primitives focus on techniques such as ECC and PUFs. Following the study selection, this review evaluates the provided security requirements alongside computational, communication, and hardware costs, while also considering application domains. It concludes by highlighting the most common approaches and identifying existing gaps in the literature. Additionally, it examines the trade-offs between attack resistance and protocol costs.https://doi.org/10.1109/access.2025.3546147https://doi.org/10.1109/ACCESS.2025.3546147https://doaj.org/article/c417792cca18470484f0b04cdf34c3f5https://hdl.handle.net/20.500.14551/2857

Integrated Microfluidic Extraction and Detection of Aflatoxin B1 in Olive Oil
No full textAbstract Food microfluidics are powerful tools to create total analysis systems and have long been demonstrated to be useful for safety and quality applications. This study introduced a new integrated aflatoxin B1 extraction and detection system based on microfluidic technology. A poly(dimethylsiloxane) microfluidic mixer was developed herein to rapidly extract aflatoxin B1 from olive oil samples. We believe that the sunflower microfluidic mixer developed in this study can be widely applied in a variety of related fields that are extremely difficult in traditional batch processes. Successful integration of microfluidic mixers brings us closer to one-step detection. The used approach allows for analysis with only 2 ml of sample. The disposable and cost-effective paper-based microfluidics were utilized to construct the immunosensor for aflatoxin B1 detection. Owing to the high surface area of paper and carbon nanotubes sensitive measurement can be done at le 0.01 nanogram levels, below the regulatory requirements. Further, the paper-based microfluidic exhibited high recoveries between 91 and 97% for aflatoxin B1 detection in olive oil, demonstrating the method’s potential for use in the study of a variety of agricultural and culinary goods.https://doi.org/10.1007/s12161-025-02827-

Urban regeneration in response to natural disasters: Insights from the 2023 Kahramanmaraş earthquakes
No full textAbstract Urban regeneration has been promoted as a key strategy for disaster risk reduction, yet its effectiveness during major natural disasters remains under-evaluated. This study addresses the central problem of assessing whether urban regeneration implementations in designated at-risk areas effectively mitigated the impacts of the 2023 Kahramanmaraş Earthquakes in Türkiye. Despite extensive urban regeneration policies under Disaster Law No. 6306, there is a notable gap in empirical research evaluating their real-world performance during significant seismic events. To fill this gap, we conducted an empirical analysis of 12 at-risk areas across 11 provinces affected by the earthquakes. Utilizing satellite imagery, regional damage proxy maps, and spatial data analysis with ArcGIS Pro, we compared pre- and post-earthquake conditions to analyze the resilience of these areas. Our results reveal a dichotomy: regenerated at-risk areas (#5, #7, #11, #12) exhibited significantly lower damage, indicating enhanced physical resilience through effective interventions. In contrast, some non-regenerated at-risk areas (#1, #9) suffered severe damage, highlighting vulnerabilities due to delayed implementations. On the other hand, other non-regenerated at-risk areas (#2, #3, #4, #6, #8, #10) experienced minimal damage, suggesting misalignment between designated risks and actual vulnerabilities. Key findings underscore the necessity for accelerating urban regeneration processes and conducting detailed risk assessments to accurately designate at-risk areas. Practical implications include policy recommendations for refining legal frameworks, establishing clear scientific standards for risk evaluation, and promoting genuine citizen participation to enhance urban resilience. This study provides novel empirical evidence on the effectiveness of urban regeneration in disaster mitigation, offering valuable insights for policymakers and urban planners aiming to strengthen the resilience of urban environments against future natural disasters.https://doi.org/10.1007/s10901-025-10213-
Design of Electrospun Hydrophobically Modified Polyacrylic acid Hydrogel Nanofibers and their Application for Removal of Ciprofloxacin
No full textAbstract The global water scarcity crisis has been exacerbated by the increasing demand for clean water and water pollution caused by the persistent release of pharmaceuticals such as ciprofloxasin, into water systems. The biodegradation and adsorption potential of CIP is crucial for its elimination in wastewater treatment systems. However conventional methods in wastewater treatment plant (WWTP) often struggle to efficiently eliminate of CIP from water due to its chemically stability and nonbiodegradability. Many researchers observed that CIP was not biodegraded even after 48 days in municipal WWTP, therefor no CIP removal occurred. The objective of this study was to investigate adsorption potential of CIP using a designed electrospun nanofiber. Within the scope of this purpose, we prepared electrospun acrylic acid (AAc)-based hydrogels modified with n-hexadecyl acrylate (C16A) for the first time and evaluated their efficacy in removing CIP from water. Our results show that the desired fiber size and surface smoothness can be obtained in the electrospun hydrogel containing 35 mol% of C16A. As a result, the AAc-based hydrogel nanofiber containing 35 mol% C16A exhibited superior adsorption properties. The adsorption efficiency of the hydrogel for CIP removal from aqueous medium was as high as 98% under equilibrium conditions. The adsorption process was found to follow the pseudo-second-order model, which suggests chemisorption as the dominant mechanism. Isothermal analysis showed that the adsorption fit well with the Langmuir model, suggesting single layer adsorption on a uniform surface. These results highlight the potential of AAc-based hydrogels for the sustainable removal of pharmaceuticals from wastewater, addressing a critical need in environmental contaminant management.
