Functional Upcycling of Polyurethane Thermosets into Value-Added Thermoplastics by Small Molecule-Assisted Carbamate Exchange during Reactive Extrusion
Background Polyurethane (PU) is a widely used plastic material that has excellent physical and mechanical properties. However, PU is difficult to recycle due to its complex chemical structure, making the effective disposal of PU waste a pressing issue. Current methods for PU disposal include incineration, which can release harmful toxins into the environment,...

Residual Glioblastoma and Glioma Cell Capture
THE CHALLENGE Physical removal of tumors in most cases cannot eradicate all the cancerous cells in the affected area. The cells that are left behind are known as residual tumor cells due to their inability to be removed. Some of these residual cells are also resistant to chemotherapy which make them particularly threatening as this is the primary method...

Personalized Medicine Using Additive Manufacturing
THE CHALLENGE A major problem posed by the pharmaceutical industry is giving effective dosages while not giving excessive amounts of a particular drug. An estimated 80% of side effects in humans and animals are a direct result of inaccurate dosing because varying weights in patients. Additive manufacturing has emerged as a very promising method to...
