The research presents the strength characteristics and theoretical mix design of full-depth reclamation (FDR) with cement for road maintenance and rehabilitation. The reclaimed aggregates used in the study were pulverized and blended on the investigation site by the recycler machine. The FDR mix design covered the reclaimed asphalt pavement (RAP), reclaimed base, and reclaimed subbase courses. The unconfined compressive strength (UCS) was tested on the FDR with cement under different mix proportions, cement content, moisture content, and curing time. Two factors that affect the UCS of FDR, viz., moisture-induced packing density and moisture for cement hydration, were observed. The mix proportion with 40% RAP required at least 6% cement to stabilize the FDR for use as a bound base course as per the standard, while the effective limit of cement content for FDR was 9%. The strength prediction model of FDR with cement was presented theoretically based on the modified soil-moisture/cement ratio concept. The verification of the proposed strength model was performed using 7 and 28-day UCS from another investigation site. The design recommendations for FDR with cement were summarized. This discovery could offer a cost-effective and precise method for the mix design of FDR with cement. © 2024, The Authors. All rights reserved.

Microplastics (MPs) and SARS-CoV-2 interact due to their widespread presence in our environment and affect the virus' behaviour indoors and outdoors. Therefore, it is necessary to study the interaction between MPs and SARS-CoV-2. The environmental damage caused by MPs is increasing globally. Emerging pollutants may adversely affect organisms, especially sewage, posing a threat to human health, animal health, and the ecological system. A significant concern with MPs in the air is that they are a vital component of MPs in the other environmental compartments, such as water and soil, which may affect human health through ingesting or inhaling. This work introduces the fundamental knowledge of various methods in advanced water treatment, including membrane bioreactors, advanced oxidation processes, adsorption, etc., are highly effective in removing MPs;they can still serve as an entrance route due to their constantly being discharged into aquatic environments. Following that, an analysis of each process for MPs' removal and mitigation or prevention of SARS-CoV-2 contamination is discussed. Next, an airborne microplastic has been reported in urban areas, raising health concerns since aerosols are considered a possible route of SARS-CoV-2 disease transmission and bind to airborne MP surfaces. The MPs can be removed from wastewater through conventional treatment processes with physical processes such as screening, grit chambers, and pre-sedimentation. © 2022, The Author(s) under exclusive licence to Iranian Society of Environmentalists (IRSEN) and Science and Research Branch, Islamic Azad University.

The pressing need for sustainable energy solutions is highlighted by the depletion of non-renewable energy sources and its effects on the environment. One of the most plentiful renewable resources, solar energy is a viable substitute to slow down global warming and improve energy security. However, geographical factors and technology developments determine its effectiveness, economic feasibility, and environmental advantages. The technical performance, economic viability, and sustainability potential of solar energy systems—photovoltaic (PV), photovoltaic-thermal (PV/T), concentrated solar power (CSP), and hybrid systems—are all thoroughly examined in this paper. This analysis contrasts various systems, stressing important economic metrics like Levelized Cost of Energy (LCOE) and environmental advantages like carbon reduction, in contrast to earlier research that concentrated on a single technology. A thorough examination of the literature was done, evaluating solar systems according to their cost, efficiency, and ability to reduce emissions in different climates. According to the results, hybrid solar and CSP systems outperform fossil fuels in terms of efficiency. PV and PV/T systems have the lowest LCOEs in terms of economics, at $0.11/kWh and $0.02/kWh, respectively. While CSP varied between $0.1219/kWh and $0.1722/kWh, hybrid systems ranged from $0.0589/kWh to $0.585/kWh. Emissions are reduced by 9.1 t CO₂/kWh with PV systems and 3.92 t CO₂/kWh with CSP. The necessity of optimizing solar technology to increase efficiency and lower prices is highlighted by this study. Solar energy has the potential to significantly contribute to the worldwide shift to sustainable energy by overcoming technological and financial obstacles. © 2025 Elsevier Ltd

The clean and renewable nature of energy harvested using the Photovoltaic (PV) technology makes it one the fastest growing technologies used in producing electricity. Due to the relatively low efficiency of the various solar cells available in the market, solar trackers and Maximum Power Point Tracking (MPPT) algorithms are used extensively to operate the system at its full potentials. Knowing that such systems are installed in outdoor spaces, they are inevitably subjected to partial shading conditions, where different parts of the system are subjected to different levels of solar irradiance. In case of occurrence of partial shading conditions on a PV system equipped with bypass diodes, the Power-Voltage (P-V) curve will have multiple peaks. This multi-peak curve requires using a sophisticated algorithm to track the Global Maximum Power Point (GMPP) instead of being deceived and trapped in a Local Maximum Power Point (LMPP). In this paper, the Crayfish Optimization Algorithm (COA) is suggested to track the GMPP of a PV system under partial shading conditions. The COA algorithm fetch for the GMPP by reading the PV panel output power and setting accordingly the duty cycle of the buck converter. Simulation is carried out using the MATLAB/Simulink platform and results demonstrate good tracking performance and prove the robustness of the system against rapid variations in solar irradiance levels.

Photoreduction CO 2 to value-added fuels (CO, CH 4 , etc.) driven by solar energy gives a green way for managing the global carbon balance. Through the radio-frequency thermal plasma treatment, fiber-like structured ZnO with rich oxygen defects were successfully designed and synthesized. The inherent one-dimensional structure enabled itself avoid aggregation during performance evolution within the humid environment and shorten the transfer path length of the photo-induced carriers and promote more electron/hole to migration to the surface of the photocatalyst. Besides, the rich oxygen vacancies could not only hinder the recombination of photo-generated electron/hole pairs, but also broaden the light absorption spectrum. Therefore, when applied in CO 2 photoreduction, the optimal fiber-like ZnO with rich oxygen defects catalyst behaved outstanding photocatalytic performance with a CO 2 -to-CO rate of 15.84 μmol g - 1 h - 1 . © 2022, The Authors.

A massive amount of solid wastes (such as straws, manures, plastic and food wastes), liquid wastes (such as municipal and agricultural wastewaters), and gaseous wastes (such as flue gases rich in carbon dioxide) are generated from industrial, residential, transportation and agricultural sectors (Siegelman et al., 2021;Vyas et al., 2022;You et al., 2022). These wastes would cause significant adverse environmental impacts if they are not properly treated. Turning wastes into biofuels and bioproducts can make a substantial contribution to the clean energy supply and environmental protection (Bhatia et al., 2018;Peng et al., 2023;Wang et al., 2023). However, competitive and sustainable circular economy solutions via scientific and technological innovation are urgently needed to improve the conversion rates and efficiencies of such *** research topic includes four original research papers, which could provide various solutions to upgrade the solid, liquid, and gaseous wastes to value-added *** digestion is a mature technology and has been developed for over a hundred years. However, anaerobic mono-digestion suffers from drawbacks such as low biogas/biomethane yield, digester instability and limited year-round availability of specific feedstocks (Karki et al., 2021). A study by Kriswantoro et al. investigated the performance of anaerobic co-digestion of untreated Napier grass and food waste hydrolyzed with subcritical water. An optimal biomethane yield of 614.37 mL/g VS was obtained at a 1:1 ratio (VS basis) of Napier grass and food waste during two-stage anaerobic digestion that sequentially produced biohydrogen and biomethane. The methane concentration in the biogas was higher than 65% on day 20 and maintained in the range of 65%-80% until the end of anaerobic digestion. Liquid digestate derived from anaerobic digestion contains high levels of nitrogen and phosphorus pollutants, which may require an energy-intensive and high-cost post-treatment

Mesocrystals, the non-classical crystals with highly ordered nanoparticle superstructures, have shown great potential in many applications because of their newly collective properties. However, there is still a lack of a facile and general synthesis strategy to organize and integrate distinct components into complex mesocrystals, and of reported application for them in industrial catalytic reactions. Herein we report a general bottom-up synthesis of CuO-based trimetallic oxide mesocrystals (denoted as CuO-M1Ox-M2Oy, where M1 and M2 = Zn, In, Fe, Ni, Mn, and Co) using a simple precipitation method followed by a hydrothermal treatment and a topotactic transformation via calcination. When these mesocrystals were used as the catalyst to produce trichlorosilane (TCS) via Si hydrochlorination reaction, they exhibited excellent catalytic performance with much increased Si conversion and TCS selectivity. In particular, the TCS yield was increased 19-fold than that of the catalyst-free process. The latter is the current industrial process. The efficiently catalytic property of these mesocrystals is attributed to the formation of well-defined nanoscale heterointerfaces that can effectively facilitate the charge transfer, and the generation of the compressive and tensile strain on CuO near the interfaces among different metal oxides. The synthetic approach developed here could be applicable to fabricate versatile complicated metal oxide mesocrystals as novel catalysts for various industrial chemical reactions.
