Integrated Design Seminar: Project-Based Learning
CM-Tech’s model draws inspiration from introductory engineering design courses at universities, where all freshman engineering students participate in a hands-on design-build-test project. At UMD, for example, every engineering and material's science student takes Introduction to Engineering Design, in which teams design, build, and race autonomous hovercraft as their first engineering design project. These courses, often called Introductory Engineering Design Seminars or Integrated Design Studios, serve to get students excited about engineering, teach teamwork and communication, introduce the design lifecycle, and develop practical problem-solving skills.
CM-Tech’s version of this course, with a working title Integrated Design Seminar in Applied Reticular Chemistry, will be organized around project-based learning where each project integrates reticular chemistry, industrial engineering, biomimicry, and global supply chain logistics. Students will work in teams across the full design lifecycle: problem definition, computational screening, laboratory synthesis, prototype engineering, field testing, supply chain analysis, and presentation.
The following projects have been identified as potential starting points:
Project 1: Biomimetic Water Harvester for Sahel Deployment Concept
Design and prototype a water-harvesting device that uses MOF-303 (aluminum-based) or similar grown in situ on fractal-patterned, leaf-like structures. The device imitates the flutter of natural leaves to maximize air exposure and uses capillary forces to transport captured water from the framework surface to a central collection point. The harvested water is deposited into demi-lune (half-moon) earthworks, a traditional Sahel water-harvesting technique being revived as part of Africa’s Great Green Wall initiative.
Technical Details
MOF-303 can capture water from air at relative humidity as low as 10-12% and release it under mild solar heating. In Death Valley tests, Yaghi’s team demonstrated passive harvesting of 210-285 grams of water per kilogram of MOF per day using only ambient sunlight. The aluminum precursor costs approximately $3 per kilogram, making MOF-303 economically viable for large-scale deployment. In-situ growth on metal foam or fabric substrates eliminates the need for separate shaping steps. Fractal-pattern leaf designs, inspired by natural phyllotaxis (leaf arrangement patterns), maximize the ratio of MOF surface area exposed to airflow per unit of device volume. The flutter-inducing geometry promotes passive airflow without requiring fans or pumps.
Potential Target Deployment
The country of Chad, where the Great Green Wall initiative originated during a 2002 summit in N’Djamena, and where demi-lune (half-moon) earthworks are already being installed to capture seasonal rainfall. These crescent-shaped depressions, typically 2-6 meters in diameter and arranged in staggered rows, are designed to capture and retain scarce rainwater. CM-Tech’s synthetic trees would be installed within these half-moons, supplementing rainfall capture with MOF-harvested atmospheric moisture deposited directly into the soil.
Supply Chain Integration
Aluminum precursors sourced from acid mine drainage in Appalachia; cellulose scaffolding from regional agricultural waste; chitosan coatings (for moisture management and antimicrobial protection) from seafood processing waste.
Disciplines Integrated
Reticular chemistry (MOF-303 synthesis and in-situ growth), biomimicry (leaf flutter, fractal patterns, capillary transport), industrial engineering (design for field installation, modular components, accessible interfaces), global supply chain logistics (West Virginia sourcing to Chad deployment, international shipping, local workforce training).
Project 2: Acid Mine Drainage Remediation and Metal Recovery Concept
Design a portable, modular system that treats acid mine drainage from abandoned coal mines, simultaneously cleaning contaminated water and recovering dissolved metals for use as MOF precursors. This project embodies the dual-benefit model: students could get paid (or at minimum source metals for free) while performing environmental remediation.
Technical Details
AMD treatment typically involves raising the pH of acidic water using limestone or lime, which causes dissolved metals (iron, aluminum, manganese) to precipitate as solid hydroxides. These precipitates can then be processed into metal salts suitable for framework synthesis. More advanced approaches can selectively recover rare earth elements, which are present in AMD at low concentrations but become economically significant when processing large volumes. West Virginia’s acid mine drainage for example contains iron and aluminum in particular abundance, both of which are common MOF metal nodes.
Design Challenges
Creating a portable, low-power system that can be deployed at remote mine sites; designing filter cartridges using MOF or chitosan-cellulose composite media for selective metal capture; engineering modular units that are easy to transport, install, and maintain by local non-specialist workers; applying accessible design principles so that maintenance does not require specialized training; developing a supply chain for recovered metals from precipitation to purification to framework synthesis.
Disciplines Integrated
Environmental chemistry, water treatment engineering, reticular chemistry (using recovered metals for MOF synthesis), industrial engineering (portable system design), supply chain logistics (from mine site to laboratory to product).
Project 3: Carbon Capture and Conversion to Fuel Precursors Concept
Design a small-scale carbon capture system using MOFs optimized for CO₂ adsorption, coupled with a conversion pathway that transforms captured CO₂ into useful chemical precursors (such as methanol or formic acid) that can serve as feedstocks for the petroleum and chemical industries.
Technical Details
Several MOF families show excellent CO₂ capture performance. MOF-5 variants, amine-functionalized MOFs, and open-metal-site frameworks like the MOF-74 family have demonstrated high CO₂ uptake capacities. Machine learning screening tools can rapidly identify the best candidates from databases of over 100,000 structures. Catalytic MOFs can drive the conversion of captured CO₂ into useful chemicals under relatively mild conditions.
Design Challenges
Selecting the optimal MOF for the specific CO₂ concentration and conditions of the target emission source; engineering a regenerable capture system (temperature-swing or pressure-swing adsorption); designing the catalytic conversion stage; analyzing the full lifecycle economics and carbon balance of the system.
Disciplines Integrated
Reticular chemistry, catalysis, process engineering, lifecycle analysis, supply chain logistics for capturing CO₂ from a specific source and delivering the converted product to market.
Project 4: PFAS and Heavy Metal Water Filtration System Concept
Design a point-of-use or community-scale water filtration system that uses MOF-based filter cartridges to remove per- and polyfluoroalkyl substances (PFAS, or “forever chemicals”) and heavy metals from drinking water. The system must be designed for easy cartridge replacement, with accessible design features that prevent installation errors.
Technical Details
The 2025 Nobel Prize announcement specifically highlighted MOFs’ potential for separating PFAS from water and breaking down pharmaceutical traces. MOF-based adsorbents have shown high selectivity for PFAS compounds and heavy metal ions. Cellulose-MOF composite beads can serve as the active filtration medium, combining high adsorption capacity with the structural integrity needed for packed-bed operation. Chitosan membranes can provide secondary filtration for particulate matter and biological contaminants.
Design Challenges
Engineering filter cartridges that are easy to manufacture, ship, and replace; applying cockpit confusion prevention principles so that cartridges cannot be installed incorrectly (different shapes, textures, or connection types for different cartridge positions); designing flow paths that minimize pressure drop while maximizing contact time; developing regeneration protocols to extend cartridge life; sourcing MOF precursors from waste streams wherever possible.
Disciplines Integrated
Reticular chemistry, water treatment, accessible design, industrial engineering, consumer product design, supply chain logistics.
Project 5: Lightweight COF-Based Hydrogen Storage for Vehicles Concept
Design a lightweight hydrogen storage module using COFs optimized for hydrogen adsorption, targeted at fuel-cell electric vehicles. COFs are preferred here because their lower density (built from light elements like carbon, nitrogen, hydrogen, and oxygen) directly reduces the weight penalty of onboard hydrogen storage.
Technical Details
Hydrogen storage is one of the most cited potential applications of porous materials. The Nobel Committee’s announcement noted that the MOF NU-1501 can store and release hydrogen at normal pressure. COFs offer similar pore tunability with significantly lower framework density. Computational screening can identify COF candidates with optimal pore geometry for hydrogen at relevant temperatures and pressures. The design challenge extends beyond the framework itself to the complete storage module: pressure vessel design, thermal management during adsorption and desorption cycles, safety systems, and integration with the vehicle’s fuel cell.
Disciplines Integrated
Reticular chemistry (COF synthesis and characterization), mechanical engineering (pressure vessel design), thermal engineering, safety engineering, automotive systems integration, supply chain logistics for lightweight materials.
Project 6: Framework-Enhanced Agricultural Soil Amendment Concept
Design a slow-release soil amendment system using framework composites that capture nutrients (nitrogen, phosphorus, potassium) and water, then release them gradually to plant roots. The amendment is manufactured from locally sourced waste materials: cellulose from agricultural residues, chitosan from seafood waste, and metals recovered from acid mine drainage.
Technical Details
MOF and COF composites can be designed to absorb and slowly release specific molecules. Combined with cellulose and chitosan carriers, these composites can be formed into granules or pellets suitable for soil incorporation. Chitosan itself has established applications in agriculture as a seed treatment and biopesticide. The combination of controlled-release nutrients, water retention, and antimicrobial properties in a single amendment could significantly benefit degraded soils, including those in the Great Green Wall region.
Disciplines Integrated
Reticular chemistry, agricultural science, materials engineering, supply chain logistics, international development.
