An International Journal of Research and Development

The Chemical Engineering Journal focuses upon seven aspects of Chemical Engineering: Applied Biomaterials and Biotechnologies, Catalysis, Chemical Reaction Engineering, Computational Chemical Engineering, Environmental Chemical Engineering, Green and Sustainable Science and Sngineering, and Novel Materials.

The Chemical Engineering Journal is an international research journal and invites contributions of original and novel fundamental research. The journal aims to provide an international forum for the presentation of original fundamental research, interpretative reviews and discussion of new developments in chemical engineering. Papers which describe novel theory and its application to practice are welcome, as are those which illustrate the transfer of techniques from other disciplines. Reports of carefully executed experimental work, which is soundly interpreted are also welcome. The overall focus is on original and rigorous research results that have generic significance.

The Applied Biomaterials and Biotechnologies section of Chemical Engineering Journal will consider papers describing the development of new functional biomaterials, biomanufacturing strategies, and/or biotechnologies with demonstrated practical applications. Theoretical calculations can be included, but all papers considered must have an experimental component. In vivo proof-of-concept demonstrations are typically expected for new biomaterials-related papers, although advanced cell/tissue models for validation of new materials or processes may also be considered. Specific topics of interest within this section include:

Biosensors for disease diagnosis (including new nanomaterials, materials interfaces, structured materials, or cell-based assays enabling sensing via electrochemical, optical, fluorescence, or other sensing mechanisms as demonstrated in a practical biological fluid), excluding the development of small molecule probes

Biological imaging materials (including new materials for enhancing contrast in new or emerging diagnostic imaging strategies)

Drug and gene delivery vehicles (including new particle, hydrogel, implant, microneedle, or other material technologies for delivering small molecule, protein, genetic, or other bioactives), excluding the development of small molecule therapeutics

Nanomedicine (including photodynamic/photothermal materials, immunotherapeutics, responsive nanomaterials, and cell-mimetic nanomaterials)

Tissue engineering and regenerative materials (including new materials, materials coatings, or materials processing techniques for improving functional tissue reconstruction/repair)

Wound healing (including hydrogels, structured polymers, and other materials that accelerate wound closure/functional repair and/or avoid wound complications)

Anti-pathogen materials and coatings (including implants, surfaces, nanoparticles, and other materials for preventing disease transmission)

Agrochemical delivery vehicles (including micro/nanomaterials and materials addressing challenges with both foliar and soil-based administration routes)

Materials for enhancing agricultural outputs (including soil conditioners, renewable mulch films or other protective materials, and cellular/soilless agriculture/food production)

Advanced in vitro models of human tissues for improved predictive screening of biomaterials (including lab-on-a-chip technologies, materials for organoid/microtissue development, and high-throughput biomaterials screening technologies)

Applied genetic engineering (including applications of CRISPR and other genome-editing technologies, design and construction of synthetic genes, and genetic/metabolic engineering of microorganisms or plants)

Artificial intelligence/machine learning in biology (including for accelerating biomaterials discovery, enabling genetic/metabolic engineering, and improving in vitro/in vivo performance correlations)

Advanced biomanufacturing technologies (including supporting materials for cell manufacturing, strategies for improved vaccine, antibody, and/or enzyme production, and scalable bioprocess development and validation)

Packaging and storage materials for food preservation/storage (including films, sprayable materials, foams, or cold storage-enabling materials)

Within the Chemical Engineering Journal, the Catalysis section presents Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis with industrial impact on chemicals, energy, materials, foods, healthcare, and environmental protection

Within the Chemical Engineering Journal, the Environmental Chemical Engineering Section presents papers dealing with emerging topics in environmental chemical and process engineering, including membrane-based separation processes in wastewater treatment, bioremediation, adsorption processes, microbial CO2 fixation, CO2 Capture, pyrolysis, sludge treatment, microbial processes, Biochar, PFAS separation and degradation, AOP processes.

Within the Chemical Engineering Journal, the Chemical Reaction Engineering section presents papers on a wide range of topics including reaction kinetics, simulation and optimization of different types of reactors, unsteady-state reactors, multiphase reactors, and process intensification including fundamental investigations of the processes of heat, mass and momentum transfer that take place along with chemical reactions. Innovative research works addressing critical areas of reactor engineering (e.g. novel reactor designs and materials, reactor safety and environmental issues), and emerging reactor technologies (e.g. membrane reactors, chromatographic reactors, unconventional fluidized bed reactors, electrochemical reactors, micro-reactors, photoreactors, fuel cells, enzymatic reactors, etc.) are particularly welcome. Submissions based entirely on e.g., numerical simulations with commercial CFD codes without novel experimental validation; novel sensing devices without a component of reaction engineering; theoretical mathematics; combustion in the context of energy conversion; or straightforward bioreactor applications (bacteria or animal cells) are highly discouraged, as these will find better fit in other existent journals.

Within the Chemical Engineering Journal, the Computational Chemical Engineering section invites submissions considering innovative development and/or application of artificial intelligence (AI), machine learning (ML), quantum mechanics (QM), molecular modeling and simulation (MMS), and computational fluid dynamics (CFD) that deal with any aspect of chemical and biological engineering. Computational research should be the primary focus, and experiments can supplement it. Also, note that  aims and scopes from other sections about computational and theoretical works are abided in this section. Topics in this section include, but are not limited to, the following: 1) new AI/ML/computational algorithms/methods applicable to chemical and biological engineering, 2) new discovery of materials with clear understanding of molecular phenomena by AI or computational methods, 3) AI-guided development of chemical process and optimization, and 4) AI/ML/computational methods for critical energy saving and sustainable environment.

Within the Chemical Engineering Journal, the Green and Sustainable Science and Engineering section presents papers focusing on innovative scientific and engineering solutions for sustainable future of human beings and nature. Topics in this section include, but are not limited to, the following: 1) Emerging materials and processes for green conversion of resources (including oil, gas, coal, biomass, plastics, and synthesis gas); 2) Green processes and system integration for renewable and clean energy production (including biofuels and H2), advanced treatment of air/water/solids, resource recovery (including nutrients, heavy metals, rare earth elements, and energy), energy-food-water nexus, and minimization of environmental pollution and hazardous materials (including environmental and economic impact assessment); and 3) Innovative separation, purification, and storage technologies for renewable and clean energy, greenhouse gases (e.g., CO2 and CH4), and intermediates/by-products.

The Novel Materials for Energy and Advanced Applications section of Chemical Engineering Journal considers papers describing the development of new functional materials and/or materials processing strategies with demonstrated practical applications. Theoretical calculations can be included, but all papers considered must have an experimental component. Any paper with a demonstrated application will be considered, including:

• Materials for sensors (gas sensors, strain sensors, electrochemical sensors, biosensors, optical sensors, or biomedical sensors provided the emphasis is new materials development) • Biomedical materials (nanomedicine, photothermal/photodynamic therapy, tissue engineering, drug delivery, wound healing, gene therapy) • Materials for agriculture (agrochemical delivery vehicles, materials for pest management) • Functional polymer composites (shape memory or self-healing materials with demonstrated applications, flame-retardant materials, adhesives, sustainable materials, thermal management materials, electromagnetic shielding materials) • Functional surfaces (superhydrophobic/self-cleaning surfaces, antimicrobial surfaces, anti-icing surfaces, anti-corrosion coatings) • Materials for photo(electro)catalytic fuel production (water splitting, nitrogen fixation, CO2 reduction) • Materials for solar cells (dye-sensitized solar cells, perovskite solar cells, organic solar cells) • Materials for electrochemical energy storage (primary and secondary batteries, flow batteries, supercapacitors, dielectric capacitors) • Materials for thermal/thermochemical energy storage/conversion (phase change materials, energy storage materials, thermoelectric devices) • Energetic materials (explosives, propellants) • Materials for electrocatalytic reactions (water splitting, hydrogen/oxygen evolution) • Light-emitting and light-filtering materials (LEDs/OLEDs, photodetectors, optical thermometry, electrochromic materials)

The GSSE section does NOT focus on traditional fabrication and modification (processes) of polymers, including membranes and porous materials, metal alloys, and construction materials. Papers pertaining to chemistry with lack of "innovative" engineering aspects, combustion and engines should be submitted to more specialized journals. Otherwise, they will be internally transferred to other journals more suited to their topic.
