DOI: 10.1016/j.bej.2017.01.020
Abstract: Abstract The flocs generated by different coagulants under various coagulation mechanisms produce fundamentally different floc characteristics. In this investigation, the fractal dimensions of aggregates produced by the different types of coagulants and coagulation mechanisms to… read more here.

DOI: 10.3390/ma10050487
Abstract: In this study, a template copolymer (TPAA) of (3-Acrylamidopropyl) trimethylammonium chloride (AATPAC) and acrylamide (AM) was successfully synthesized though ultrasonic-initiated template copolymerization (UTP), using sodium polyacrylate (PAAS) as a template. TPAA was characterized by an… read more here.
