BACKGROUND Mixing 5-hydroxytryptamine-3 (5-HT3) receptor antagonists with patient-controlled analgesia (PCA) solutions of tramadol has been shown to decrease the incidence of nausea and vomiting associated with the use of tramadol PCA for postoperative pain. However, such mixtures are not commercially available, and the stability of the drug combinations has not been duly studied. The study aim...

Catalytic cracking could enable low temperature conversion of hard-to recycle polyolefin plastics. However, traditional catalysts suffer from macro and microscopic mass transport limitations, which call for plastic pre-treatment.

Efficient catalysis that simultaneously cleaves thermodynamically inert C–C bonds and generates functional moieties to stimulate chemical recycling of polyolefins is lacking. In this issue Chem, Kanbur et al. design an organozirconium catalyst combined with aluminum reagents enable a clever tandem cleavage carboalumination process yields value-added alkylaluminum products. With their ubiquitous...

a two-dimensional single particle finite element model was used to examine the effects of particle fragmental pattern on the average molecular weights, polymerization rate and particle overheating in heterogeneous ziegler-natta olefin polymerization. a two-site catalyst kinetic mechanism was employed together with a dynamic two-dimensional molecular species in diffusion-reaction equation. the i...
