Call for papers/Topics

Full Articles/ Reviews/ Shorts Papers/ Abstracts are welcomed in the following research fields:

1. Green Chemical Engineering

This pillar focuses on the "Twelve Principles of Green Chemistry" and the design of chemical processes that reduce or eliminate hazardous substances.

Green Synthesis & Reaction Engineering

Alternative Reaction Media: Ionic liquids, Deep Eutectic Solvents (DES), supercritical fluids (e.g., $scCO_2$), and "on-water" chemistry.

Catalysis: Homogeneous and heterogeneous catalysis, biocatalysis (enzymatic reactions), and organocatalysis.

New Synthetic Pathways: Photochemistry, electrosynthesis, and mechanochemistry (solvent-free grinding).

Process Intensification: Micro-reactors, continuous flow manufacturing, and multifunctional reactors.

Product Design & Material Science

Biodegradable Polymers: Design for degradation, bioplastics (PLA, PHA), and sustainable packaging.

Renewable Feedstocks: Biomass-to-chemicals, lignin valorization, and CO? as a C1 building block.

Inherently Safer Chemistry: Minimizing explosion risks and toxicity through chemical molecular design.

Green Metrics: Calculating Atom Economy, E-factor, and Process Mass Intensity (PMI).

2. Energy Sciences

This pillar focuses on the transition from fossil fuels to clean, renewable sources and the engineering required to store and transport that energy.

Renewable Energy Systems

Solar Energy: Next-generation photovoltaics (perovskites, organic PV) and concentrated solar power.

Hydrogen Economy: Green hydrogen production (electrolysis), hydrogen storage (hydrides, MOFs), and fuel cell engineering.

Bioenergy: First to fourth-generation biofuels, anaerobic digestion, and thermochemical conversion (pyrolysis/gasification).

Wind & Hydro: Turbine aerodynamics, offshore wind technology, and wave/tidal energy conversion.

Energy Storage & Management

Advanced Batteries: Solid-state batteries, lithium-sulfur, flow batteries, and sodium-ion technologies.

Supercapacitors: High-power density storage and carbon-based nanomaterials.

Thermal Energy Storage: Phase-change materials (PCMs) and sensible heat storage for industrial use.

Grid Integration: Smart grids, micro-grids, and power-to-X technologies.

3. Environmental Sciences & Engineering

This pillar focuses on monitoring, protecting, and restoring the natural environment using engineering tools.

Pollution Control & Remediation

Water & Wastewater Treatment: Membrane filtration (RO, FO), Advanced Oxidation Processes (AOPs), and desalination.

Air Quality Engineering: Carbon Capture, Utilization, and Storage (CCUS), VOC abatement, and NOx/SOx scrubbers.

Bioremediation: Using microbes or plants (phytoremediation) to clean contaminated soil and groundwater.

Waste Valorization: Circular economy models, plastic upcycling, and electronic waste (e-waste) recovery.

Sustainability Systems & Assessment

Life Cycle Assessment (LCA): Cradle-to-grave analysis of products and "Environmental Footprinting."

Industrial Ecology: Symbiosis where one industry's waste becomes another's raw material.

Climate Science: Atmospheric modeling, carbon cycle analysis, and ocean acidification studies.

Environmental Policy: Carbon pricing, environmental justice, and international sustainability protocols.

Emerging Cross-Disciplinary Trends

AI in Green Engineering: Machine learning for catalyst discovery and process optimization.

Nano-Environmental Science: Using nanomaterials for high-efficiency sensing and pollutant removal.

Urban Ecology: Sustainable city planning and green infrastructure.
