Evaluating clean energy strategies for national carbon neutrality: An interdisciplinary policy-focused decision framework

This study aims to evaluate and prioritize clean energy strategies to support Türkiye's national carbon neutrality goals. Achieving carbon neutrality requires adopting clean technologies and effective environmental policy tools. This study presents a novel multi-criteria decision...

Narrative Resonance and Ontological Instability in Jeff VanderMeer’s Annihilation

This article uses narrative resonance as a theoretical approach to examine the narrative and ontological instability in VanderMeer’s novel Annihilation. The study adopts a qualitative research design based on document analysis, with the novel as the primary source. The analysis i...

Supramolecular Crosslinking-Based Photosensitizing Nanogels via Host−Guest Assembly for Targeted Photodynamic Therapy

Abstract Over the past decade, nanogels (NGs) have emerged as a promising drug delivery platform for targeted cancer therapy. Herein, we report the design and fabrication of a multi-functional photosensitizing nanogel system for photodynamic therapy (PDT) based on supramolecularl...

The spatial crises of capitalism and in-between spaces as an instrument of urban production: the case of Galataport

This study examines the ontological transformation of in-between spaces from the 1960s to the present, within capitalism’s spatial crises. While previous literature has viewed these spaces as idle voids or symptoms of spatial segregation, this study reimagines them as dynamic mod...

Stress Reduction of Buried Thermoplastic Pipes Using EPS Geofoam

Field and laboratory tests and numerical analyses of rigid culverts have shown that induced trench installation (ITI) can reduce the vertical stress acting on culverts installed under high embankments. In this research, the ITI technique was adapted by incorporating expanded poly...

A Comprehensive Review of Battery State of Health Estimation: Methods, Challenges and Future Perspectives

Lithium-ion battery state of health (SOH) cannot be measured directly and must be inferred from capacity, resistance, voltage, current, temperature, and usage history. This structured narrative review integrates degradation mechanisms with feature-based, model-based, data-driven,...

A new heat sink for cooling photovoltaic systems using a honeycomb heat sink filled with multiple phase change materials

The electrical efficiency of photovoltaic (PV) cells is significantly influenced by their operating temperature. As the temperature increases, the power output decreases; therefore, effective thermal management is essential to maintain conversion efficiency and maximize energy pr...

Underwater-Mission-Oriented Objective Function Design for Metaheuristic Tuning of PID and Fractional-Order PID Controllers

Metaheuristic tuning of depth controllers for remotely operated vehicles is usually performed against a generic error integral, which does not encode mission priorities such as battery use, actuator stress from chattering, direction-dependent overshoot risk and post-event recover...

On the soliton and numerical solutions to the Nurshuak–Tolkynay–Myrzakulov-II-Equation

Abstract The Nurshuak–Tolkynay–Myrzakulov-II-Equation, which is (1 + 1)-dimensions integrable equation, considered one of the nonlinear models that very naturally arise inspect dealing with the mean field approximation of many-body systems, including various important phenomena l...

Durability Assessment of Hydraulic Lime Grouts Incorporating Cappadocia Waste Earth Under Selected Environmental Exposures

Hydraulic lime grouts are widely used for masonry consolidation, yet their environmental durability remains insufficiently understood. This study evaluated natural hydraulic lime (NHL) grouts incorporating Cappadocia Waste Earth (CWE) at CWE/NHL mass ratios of 0–0.50, while maint...

Analytical applications of molecularly imprinted polymers: a personal view

Abstract Molecularly imprinted polymers (MIPs) are biomimetic counterparts of biomacromolecules that are synthesized by templating the target within a polymeric network. While the affinity of MIPs can compete with that of antibodies, the specific activity of natural enzymes remai...

Structural characterization and CO2 adsorption enhancement of synthesized calcined flower-like Mg–Al LDH@γ-Al2O3

Abstract Flower-like Mg–Al CO 3 layered double hydroxides (LDHs) grown on γ-Al₂O₃ substrates with varying Mg:Al molar ratios (2:1 and 3:1 in the precursors( were successfully synthesized via a controlled co-precipitation method. The structural morphology, composition, crystallini...
