Welcome back to the Project Clean Up (PCU) weekly newsletter! We have the "Unbreakable Seal" in our metals; now, we give our extreme hardware its "Skin." This week, we introduce Cryo-Resilient Vitrimers.

Welcome back to the Project Clean Up (PCU) weekly newsletter! We have perfected the "Transient Suite" for our cities and oceans. Now, we look at the Extreme Frontier.

Welcome back to the Project Clean Up (PCU) weekly newsletter! We are concluding our "Total Transient Suite" with the most efficient production method known to science: Self-Assembly.

Welcome back to the Project Clean Up (PCU) weekly newsletter! We have successfully built a transient physical suite; now, we give it a brain. This week, we explore Organic Neuromorphic Computing.

Welcome back to the Project Clean Up (PCU) weekly newsletter! We are concluding our "Total Deconstruction" series with the most difficult component to neutralize: the battery. This week, we introduce Probiotic Biobatteries.

Welcome back to the Project Clean Up (PCU) weekly newsletter! We have reached a milestone in our "Post-Metal" series. By combining the liquid connections and 2D shielding from previous weeks with Water-Soluble Biopolymer Substrates, we can now conceptualize a device that truly "disappears" when its job is done.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we explored MXenes as the silver-slayer in shielding. This week, we tackle the connection itself: Gallium-based Liquid Metal Alloys.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we explored the "Post-Metal" shift toward Carbon Nanotubes and Graphene. This week, we introduce the next powerhouse in that lineup: MXenes.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we investigated FOSA and the dangers of volatile chemical "bridges." This week, we pivot to the very hardware that powers our world: the search for alternatives to copper, silver, and gold.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we looked at the "chemical magnets" of DAC Sorbents and how they are scrubbing our atmosphere. This week, we focus on a compound that often hitches a ride in that same atmosphere: FOSA (Perfluorooctane Sulfonamide).

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we assessed our 2026 trajectory and the global shift toward destructive remediation. This week, we pivot to a material that doesn't just clean our water, but cleans our air: Direct Air Capture (DAC) Sorbents.

Welcome to the first full update of 2026! Last week, we closed out the year by unmasking the "replacement trap" of GenX. As we enter this new year, the focus of PCU is Scale.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we explored the molecular architecture of MOFs, the molecular sponges helping us capture pollutants with extreme precision. This week, we return to the "forever chemical" frontline to discuss GenX (Hexafluoropropylene Oxide Dimer Acid).

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we explored the catalytic solution for PFPEs, proving that targeted chemistry is the key to dismantling even the most stable lubricants. This week, we pivot to a material that is revolutionizing filtration and storage: Metal-Organic Frameworks (MOFs).

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we celebrated the engineering marvel of Synthetic Spider Silk, a material designed for superior strength and natural biodegradability. This week, we confront a different kind of advanced material: Perfluoropolyethers (PFPEs).

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we celebrated the engineering marvel of Synthetic Spider Silk, a material that is both strong and completely biodegradable. This week, we confront another chemical challenge: Perfluorobutane Sulfonamide (PBSA).

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we confronted the bioaccumulative threat of PFDA, a long-chain "forever chemical." This week, we're pivoting to a thrilling innovation that takes inspiration directly from nature: Synthetic Spider Silk.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we explored the promise of Self-Healing Circuits, a sustainable solution for infrastructure longevity. This week, we confront Perfluorodecanoic Acid (PFDA), a "forever chemical" that poses a major threat due to its extreme persistence and tendency to bioaccumulate.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we faced the vast challenge of Airborne PFAS and how these "forever chemicals" contaminate the globe. This week, we're pivoting to a thrilling innovation in advanced materials: Self-Healing Electronic Circuits.

Welcome back to the Project Clean Up (PCU) weekly newsletter! Last week, we explored the fascinating world of Quantum Dots, showcasing their power in displays and energy. This week, we're zooming out to discuss a massive environmental challenge: PFAS contamination in the atmosphere.
