Molecular and oligomeric amines supported in porous oxide supports are a promising class of CO2 sorbent materials studied for removal from diverse streams such as flue gas ambient air. Among the various investigated, low molecular weight, hyperbranched poly(ethyleneimine) (PEI), tetraethylenepentamine (TEPA) among most extensively studied. While macroscopic structure–performance relationships r...

In the field of the tumor-inhibitory cytotoxic alkylating agents, there have thus far been few attempts to determine the nature and occurrence of drug metabolites in animal experiments; none has been made in humans. Nadkarni et al. (7) have shown that the principal urinary metabolite of ring-labeled TEM given to mice is cyanuric acid, whereas, when the ethyleneinime-labeled TEM is administered,...

The secondary amines found in b-PIBSI dispersants prepared by attaching two polyisobutylene chains to a polyamine core via two succinimide moieties were reacted with ethylene carbonate (EC). The reaction generated urethane bonds on the polyamine core to yield the modified b-PIBSI dispersants (Mb-PIBSI). Five dispersants were prepared by reacting 2 molar equivalent (meq) of polyisobutylene termi...
