Biochar, which is a C-rich material produced through pyrolysis of organic materials has been recognized as a multifunctional material for energy and environmental applications. Biochar has known to increase nutrient and water retention in soil, enhancing crop productivity, and eliminate in/organic contaminants from soil and water and reduction of greenhouse gas emission.
During recent years, extensive attention has been gained on the modification of biochar with novel structures and surface properties to enhance its remediation efficacy and environmental benefits (e.g., designer vs engineered biochar).
The aim of the proposed special issue is to publish selective novel on-going research contributing to the innovative and effective thermochemical conversion process of biowaste for various energy and environmental applications.
Different topics may be considered useful to contribute to this special issue and for further development and application of biowaste, including
· Sustainable waste management through production of value-added products
· Novel engineering methods to prepare designer/engineering biochar
· Application of designer/engineered biochar for effective removal of hazardous materials
· Production of low risk and environment-frendly biochars (designer/engineered biochars) with reduced toxicity and contaminants content
· Potential risks and environmental impacts of designer/engineered biochar
· Nanotechnology for biochar properties improvement regarding to energy and environmental applications

Special Issue on Advanced Oxidation Technologies for Environmental Protection
The increasing demand for clean and safe water represents a major challenge for economic development and public health. The widespread use of synthetic organic compounds (SOCs) has raised environmental concerns due to their presence in aquatic environments, bioaccumulation along the food chain, and recalcitrance to conventional water treatment technologies. The increasing number of emerging and complex contaminants makes it more difficult for current centralized treatment facilities to treat the SOCs. Avoiding the use of SOCs is unlikely, because they are of essential medical and industrial importance. Therefore, there is an acute need to develop technologies that can effectively control the SOCs. While considerable effort has been exerted on improving SOCs removal efficiencies by different conventional water treatments, advanced oxidation technologies (AOTs) have shown to be more efficient than the conventional ones. However, the development of AOTs is still challenged by several drawbacks such as toxic by-product formation, high energy cost, special requirement for reactor design, etc. This special issue is dedicated to state-of-the-art AOPs for environmental protection, particularly in water. Diverse topics related to AOTs will be covered including but not limited to:
1. Recent advances in AOTs for wastewater treatment and reuse
2. Treatment of emerging synthetic organic compounds (e.g., PFAS)
3. Photochemical processes
4. Ozonation
5. Ultrasonic processes
6. Electrochemical oxidation
7. Disinfection
8. New materials for the application of AOTs;
9. Hybrid treatments
10. Toxicity reduction.

Journal of Aerosol Science
Special Issue on Low-Cost Portable, Wearable, and Distributed Sensors
The Journal of Aerosol Science is delighted to invite authors to submit papers for our virtual issue onLow-cost portable, wearable, and distributed sensors.
The increasing availability and quality of low-cost aerosol sensors promise to provide researchers, communities, and policy makers with measurements having unprecedented spatial and temporal resolution. Researchers have begun to use these sensors to understand questions ranging from personal aerosol exposure to identifying pollution hot spots, and networks of these low-cost sensors have begun reporting aerosol concentrations to the public. However, these low-cost sensors pose challenges from a data quality and communication perspective. Consequently, the Journal of Aerosol Science is requesting papers on the topic of low-cost sensors.
We encourage research papers on how low-cost aerosol sensors are being evaluated and used by scientists and communities. This issue also seeks papers on some of the challenges to the use of low-cost sensors including data quality, the true cost of operating a sensor network, and communicating results to the public .
We invite authors to submit papers on (but are not limited to) the following topics:
The development and evaluation of new low-cost aerosol sensors;
Studies that demonstrate the use of low-cost sensors to identify poorly understood phenomena in indoor and outdoor environments;
The use of low-cost sensors to understand and/or address environmental justice challenges;
Strategies for addressing the data-quality challenges associated with low-cost sensors;
The use of low-cost sensing to understand personal exposure to aerosols;
Strategies for integrating low-cost sensor data into metrics that can be used by the public;
Using low-cost sensors to engage the public, including educational tools;
The use of low-cost sensors and potential challenges in mobile applications.

Chemical Engineering and Processing: Process Intensification
Special Issue on Advances in process intensification of fluidization
Fluidization is one of the most encountered processes in chemical engineering, and will continue to play indispensable role in chemical industries in the future. Though fluidization has been studied for a long time, due to its highly complex nature, significant efforts are still devoted to increase its productions and reduce its consumptions. Actually, process intensification has been one of long-term key orientations in knowledge and technology developments for fluidization. In recent years, due to industrial upgrading, process intensification has received particular attention from both economic and environmental aspects. Increased developments of new principles for process intensification of fluidization have emerged and advances of this field have entered into a new era. To this end, collecting papers from worldwide active researchers showing the cutting-edge directions of process intensification of fluidization is highly beneficial to future developments in this direction. Though in the last decade, especially the recent five years, a sheer volume of scientific papers have been published, to the best of our knowledge, there has not been a special issue so far specifically devoted to highlight the current status and future directions of process intensification of fluidization.
The aim of this special issue is to present readers a high-level platform for active researchers to report their most up-to-date progress in process intensification of fluidization. Developments and applications of principles, such as reactor structuring, synergistic combination (in the reactor) with an adsorption/membrane separation process, specific tuning of the dynamics, and the use of electrical or magnetic forces, for process intensification of fluidization are the main scopes of this special issue. Both original research articles and comprehensive review and feature papers are anticipated in this special issue, from which we hope to summarize the true wavefront in advances of process intensification of fluidization. Papers in all aspects related to process intensification of fluidization, including theoretical, experimental, and numerical studies, from laboratory- to industry-scale fluidized beds are welcome. Interested authors please submit your manuscripts through the journal’s electronic paper submission system and choose special issue “VSI: Adv-PI-fluidization”. All submitted manuscripts will undergo strict peer review for quality purpose. Potential authors can contact any of the Guest Editors to discuss the suitability of their manuscripts to this special issue.

Special Issue on Novel Technologies and Methods for Plastics Recycling
The special issue aims to publish high quality papers related to recovery and recycling of waste plastics. As the production of waste plastics is increasing significantly, it causes great environmental challenges. In addition, waste plastic itself contains valuable chemicals and has a very high calorific value. Although extensive efforts are being made to advance the reduction, reuse and recycling of waste plastics, advanced technologies producing high-value products have not been commercialized widely yet. Therefore, this special issue aims to identify current challenges and propose novel solutions for waste plastic management, with the goal of enhancing economic profits as well as environmental and societal benefits.
Papers that fall within the scope of the issue as outlined below are invited for submission.
