Abstract Nanotechnology is the field of science that has achieved remarkable advances over the past few decades, enabling significant developments in biomedical, chemical, and environmental applications. The rapid expansion of nanomaterial research has led to the synthesis of a wide variety of nanoparticles and nanostructured materials with exceptional functional properties. However, alongside performance optimization, increasing attention is being directed toward the sustainability, environmental impact, and greenness of nanomaterial synthesis routes. Despite this growing concern, a standardized and user-friendly tool for simultaneously evaluating nanomaterial performance and green synthesis conditions is still lacking. In this work, we introduce the Nanomaterials Assessment Tool (NAT), a novel, open-access software, available at https://nattool.az3093.info/NanoTool, It is designed to systematically assess nanomaterials based on both their functional performance and the extent of greenness in their synthesis processes. NAT evaluates four main aspects: the nature of materials and reagents used, the sustainability of synthesis conditions, the properties of the synthesized nanomaterial, and its applicability. The tool consists of sixteen carefully designed evaluation questions with a quantitative scoring system with a maximum total score of 100 supported by visual illustrations. By providing a standardized assessment framework, NAT aims to encourage researchers to adopt green precursors, optimize eco-friendly synthesis strategies, and minimize environmental impact without compromising material performance. The tool is applicable to a wide range of nanomaterials, including metallic nanoparticles, carbon-based nanomaterials, nanozymes, metal–organic frameworks, and nanocomposites.

Managing wireless infrastructure is very essential and crucial after natural disasters such as earthquakes, hurricanes, landslides or man-made disasters such as wars. Rapid information gathering after a disaster helps in achieving effective communication management, as the pressure of users to maintain constant communication with family and friends causes bottlenecks and communication failures for other users. Device-to-device (D2D) communication technology reduces this pressure by relying on the proximity of users, thus increasing the efficiency of spectrum utilization. A many-to-many matching algorithm with an adaptive splitting factor and reuse factor was proposed for two scenarios and the results were evaluated using MATLAB simulation software. The results showed that the proposed algorithm outperforms the recently used Gale-Shapley matching algorithms in achieving effective management of radio resources in emergency situations, and it also succeeded in improving productivity and serving a larger number of users effectively.

Managing wireless networks is crucial after natural disasters or conflicts, where communication systems often become overloaded due to high demand. Device-to-device (D2D) communication helps reduce network congestion by allowing nearby users to communicate directly, improving spectrum efficiency. A many-to-many matching algorithm with adaptive parameters was proposed and tested using MATLAB simulations. The results show that the proposed method outperforms the Gale-Shapley algorithm in managing radio resources during emergencies, improving efficiency and supporting a larger number of users

The research addresses vertical boxy buildings that emerged widely after the Industrial Revolution, focusing on height and function but often neglecting environmental and human aspects. These buildings have led to issues such as high energy consumption, poor natural ventilation and lighting, social isolation, and weak contextual integration. As a result, rethinking their forms has become necessary. The study analyzes recent morphological transformations such as zigzagging, stepping, and perforation of building masses aimed at improving environmental and functional performance. It concludes that most of these design modifications primarily target sustainability and performance enhancement, emphasizing the importance of linking form and function and avoiding repetitive designs without contextual evaluation.

This paper proposes a novel energy-efficient routing protocol for Underwater Wireless Sensor Networks (UWSNs) based on the Ant Colony Optimization (ACO) algorithm. Inspired by the foraging behavior of ants, artificial ants explore possible paths from underwater sensor nodes to surface sinks, depositing virtual pheromones that evaporate over time. The proposed protocol selects optimal routes based on multiple criteria: residual node energy, node depth, acoustic channel quality, and distance to the surface. Compared to traditional routing protocols (DBR, EEDBR), the ACO-based protocol demonstrates significant improvements in packet delivery ratio, reduced energy consumption per node, and balanced traffic load distribution, ultimately extending the overall network lifetime

The Demand of IPTV (Internet Protocol Television) services is growing significantly in the mobile communications industry. To support a large number of users with limited radio sources, the effective transmission technology for television content has to be developed. In this research, we suggest integration of static and dynamic segmenting algorithms for television content to improve QoS (Quality of Service) of VoD (Video on Demand) service over the IPTV wireless network in the LTE (Long Term Evolution) system. Performance have been evaluated by simulating the system using MATLAB, where the results have shown an improvement in performance of the proposed alogorithm; this improvement in performance have been evaluated in terms of BER and Delay time.

So it’s very interesting topics how to deliver IPTV VOD service to a mobile subscriber by providing high QoS(Quality of Service) in 4G networks especially LTE(Long Term Evolution).The most important QoS parameters are bit error rate (BER) and delay time which make IPTV VoD service unsatisfied and not acceptable if they're under the limit. In this research, we have worked on enhancing chopping television content and setting in physical channels in LTE networks. Performance have been evaluated by simulating the system using MATLAB; where the results showed an improvement in performance of the proposed alogorithm; this improvement in performance have evaluated in terms of BER and Delay time

Biological treatment is considered one of the effective and economic ways to address phenol treatment by biodegradation as compared with high cost methods of physical and chemical processing. The method is of low efficiency when applied to high concentrations, in addition to formation of secondary compounds that may be more dangerous than the target material The study focused on use of three isolates, i.e.

Wastewater emerging from poultry technical slaughterhouses is characterized by its high degree of pollution in terms of organic content. This causes a rise in organic load disposed to wastewater treatment plants and thereby drooping efficiency. Effective and economical ways to treat such wastewater, based on reducing concentration of organic loads to appropriate level, preserves environs and reduces treatment costs for owners of industrial plants without augmenting investment costs. Aerobic Moving Bed Biofilm Reactor (MBBR) technology based on biofilm phenomenon is advocated in this research work.

Mathematical modeling is used in different science domains. By using it we can construct several mathematical models. Solving these models, mostly, depend on numerical approximate methods, and especially the case when these models are represented by the system of linear or nonlinear equations. To solve these equations we depend on generation solutions with repeated forms such as Gauss, Gauss. Zaidl, Fixed Point, Newton, and Broyden methods. Beginning from an elementary value, which is a chosen estimation, and on which we depend, we determine the speeding of the convergence and the accusation of the solution which we get by certain accuracy.
