Ultrafast Removal of Thorium and Uranium from Radioactive Waste and Groundwater Using Highly Efficient and Radiation-Resistant Functionalized Triptycene-Based Porous Organic Polymers.

Thorium (Th) and uranium (U) are important strategic resources in nuclear energy-based heavy industries such as energy and defense sectors that also generate significant radioactive waste in the process. The management of nuclear waste is therefore of paramount importance. Contamination of groundwater/surface water by Th/U is increasing at an alarming rate in certain geographical locations.

Ethyl Cellulose-Assisted Host-Guest Framework for Depositing Solution-Processed Yttria Films on the Inner Surface of a Narrow Quartz Tube.

Straightforward deposition protocols to coat flat surfaces are widely available. However, there are multiple constraints in coating a concave or convex surface, especially on the inner surface of narrow tubes. Coated surface helps in corrosion protection, internal cleanliness, strength, and alloy casting, and it also enhances product aesthetics.
