Passive Direct Air Capture Telescoping Device
Background Carbon dioxide (CO2) emissions are a leading cause of climate change. The removal of CO2 from the atmosphere is a critical factor in mitigating climate change. Passive direct air capture of CO2 is an effective technique for the reduction of CO2 as it reduces the resources required and can easily be integrated with existing systems. There...

AUDACity: DAC Polymer-Enhanced Cyanobacterial Bioproductivity
Background Carbon dioxide removal (CDR) methods from atmospheric air, including direct air capture (DAC), is essential to limit the spread of global warming. However, current DAC approaches based on thermal and pressure swings are very energy intensive. Moisture-driven DAC using strong-base anion exchange resins (AER) reversibly binds CO2 from ambient...

Multiblock Copolymers for Moisture Swing Direct Air Capture
Background Polysulfones have been increasingly studied in recent years as a class of thermoplastics with excellent strength and thermal stability used in nanofiltration, energy storage, and biochemical separation. Quaternary ammonium polymers are another class of materials that tend to have high conductivity and good ion exchange properties. Copolymers...

Poly(Tetramethylene Oxide)-Based Segmented Ionenes Block Copolymer with Aliphatic or DABCO Hard Segments
Background Ionenes contain charges in their polymer backbones, as opposed to traditional ionomers that have charges on the pendant site of the backbone. Ionenes, whether positive or negative, typically fall into two categories- either segmented or non-segmented. Segmented ionenes contain alternating hard and soft segments along the polymer backbone,...

Scoop Device for Passive Capture of CO2
Background Carbon dioxide (CO2) capture technology has the potential to alleviate greenhouse gas emissions and mitigate climate change. There are several types of technology that are currently being used to capture and store CO2 such as Direct Air Capture (DAC), power plants, enhanced rock weathering (ERW), etc. Carbon capture technologies are typically...

Digestion of PET using Long Chain Alcohols
Background Poly(ethylene terephthalate) (PET) is a commodity plastic that is used in many types of single-use applications (e.g., to-go containers, food packaging, water bottles). The accumulation of plastic waste in landfills and in the environment is fueling a greater push to advance polymer recycling technology. Chemically recycling plastics to...

Membrane Contactor for Simultaneous Desalination and Co2 Removal From Seawater
Background To address the pressing issue of climate change resulting from excessive CO2 levels in our atmosphere, an array of innovative negative emission technologies must be scaled and implemented for carbon removal. Discussions concerning these technologies often surround Direct Air Capture (DAC); however, Direct Ocean Capture (DOC) is an exciting...

Design and Application of Form Factors for Sorbent Materials
Background Many current air-capture designs feature flat air contactor surfaces with air flow predominantly tangential to those surfaces. In many cases, it may be advantageous to induce some turbulence across the sheet to enhance transport into the depth of the material. In general, it is advantageous to create surface roughness that is designed to...

Zwitterion Anti-Scaling Membrane Coatings
Background Water reclamation for space flight applications (e.g., International Space Station (ISS)) requires complex engineering solutions to ensure maximum water recovery. Current vapor compression distillation (VCD) technologies are effective but produce highly concentrated brines and often cause scaling within a separation system. Scaling in water...

Electrospun Poly(Vinyl Alcohol) – L-Arginine Nanofiber Composites for Direct Air Capture of CO2
Background The accumulation of carbon dioxide (CO2) in the atmosphere has been documented to be the primary driver of global warming. The global average CO2 levels in the atmosphere continue to rise, with a predicted 1.5°C increase in global temperatures within the next two decades. The capture and storage of CO2 is an essential part of mitigating...
