Abstract

Growing environmental concerns regarding plastic pollution, fossil resource depletion, and greenhouse gas emissions have intensified efforts to develop sustainable alternatives to petroleum-based polymers. Agricultural waste provides biomass containing cellulose, hemicellulose, starch, and lignin that can be transformed into biodegradable polymers through responsible synthesis pathways. Green chemistry offers a framework for reducing hazardous chemicals, energy consumption, and resource inefficiency while supporting circular bioeconomy principles. This study evaluated green chemistry strategies for producing biodegradable polymers from agricultural waste while enhancing polymer performance, sustainability, and industrial feasibility. A mixed-methods sequential explanatory design involved 480 biomass samples and 210 laboratory- and pilot-scale synthesis experiments representing conventional, optimized, and sustainable production pathways. Quantitative data were analyzed using descriptive statistics, structural equation modeling, hierarchical regression, mediation, and moderation analyses. Qualitative evidence from expert interviews, industrial observations, lifecycle assessments, and policy documents was examined thematically. Findings showed that integrated green chemistry improved biomass conversion efficiency, polymer yield, molecular stability, biodegradation, catalyst recovery, energy efficiency, and lifecycle sustainability. Catalyst recovery partially mediated the relationship between green chemistry implementation and environmental performance, while reaction optimization strengthened the effect of biomass conversion on polymer quality. Sustainable production therefore requires coordinated biomass use, catalyst innovation, process optimization, and circular economy strategies.

Abstract

The rapid depletion of forest ecosystems worldwide has led to an increasing need for sustainable forest management practices. One promising approach to incentivize conservation efforts is the implementation of Payment for Ecosystem Services (PES) programs. PES aims to financially reward individuals or communities who provide ecological services, such as maintaining forest cover, conserving biodiversity, and improving water quality. Despite growing interest in PES, its effectiveness as a tool for sustainable forest management remains an area of active research. This study aims to evaluate the effectiveness of PES programs in promoting sustainable forest management and enhancing the livelihoods of local communities. Specifically, the research examines the impact of PES on forest conservation practices, economic benefits for participants, and the long-term sustainability of forest ecosystems. A mixed-methods approach was used, combining both qualitative and quantitative data. Surveys were conducted with 150 households involved in PES programs across three forest regions. In-depth interviews with local stakeholders, including forest managers, government officials, and community leaders, were also carried out. Data was analyzed using descriptive statistics and thematic analysis to assess the outcomes of PES programs. The findings suggest that PES programs have led to increased forest conservation efforts, improved local livelihoods, and greater awareness of ecosystem services. However, challenges such as inadequate funding, lack of technical support, and limited participation of marginalized groups were identified as barriers to full program effectiveness. PES programs can be a viable tool for sustainable forest management, provided that they are properly funded, inclusive, and supported by strong governance frameworks. Long-term success will depend on overcoming existing challenges and ensuring equitable participation.

Abstract

Quantum teleportation through optical communication channels is one of the promising technologies to create secure communication systems in the future. This study aims to evaluate the efficiency of quantum teleportation through various types of optical communication channels, such as standard optical fibers, low-loss optical fibers, and free photon-based communication lines. The research was conducted using a quantitative experimental method, measuring the success rate of teleportation based on channel length, channel type, and environmental disturbances. The results showed that low-loss optical fibers had the highest efficiency, with a success rate of 85% at distances of up to 50 km. The free photon-based path shows good performance at short distances, but decreases drastically at longer distances due to atmospheric disturbances. The study also found that photon loss and environmental disturbances are the main factors affecting entanglement stability, especially in channels more than 75 km long. The conclusion of this study confirms that low-loss optical fiber is the best choice to support quantum teleportation on a local to medium scale. The main challenges in the development of this technology are the reduction of photon loss and the management of environmental disturbances. Further research is needed to address these limitati

Abstract

The limitations of conventional von Neumann computing architectures in handling complex, data-intensive tasks have spurred significant interest in brain-inspired neuromorphic computing. A critical challenge in this field is the development of hardware that can efficiently emulate the synaptic plasticity of biological neurons. This study focuses on the synthesis, characterization, and integration of ferroelectric thin films, specifically hafnium zirconium oxide (HZO), as a promising material platform for creating artificial synaptic devices. The primary objective was to fabricate high-quality HZO thin films and demonstrate their capacity to mimic key synaptic functions. HZO films were synthesized using pulsed laser deposition, followed by comprehensive characterization of their structural, ferroelectric, and electrical properties using XRD, PFM, and I-V measurements. The optimized films were then integrated into two-terminal memristive device structures. The resulting devices successfully exhibited essential synaptic behaviors, including potentiation, depression, and spike-timing-dependent plasticity (STDP), with low energy consumption per synaptic event. The gradual and controllable modulation of ferroelectric domain switching was identified as the core mechanism enabling this analog-like resistance modulation.
