A quantum model solving the charge copyright mobility between polyacetylene-like polymer nanorods is presented.The model assumes: a) Quantum mechanical calculation of hole on-chain delocalization involving electron-phonon coupling leading to the Peierls instability, b) Hybridization coupling between the polymer backbone and side-groups (or environm
The sorption capacity of untreated and alkaline-treated coconut shaft biosorbents for the removal of Pb2+ from click here aqueous solution was investigated in batch experiments.Effects of contact time, biosorbent dose, initial metal concentration, and pH on the sorption capacity were investigated.Optimum Pb2+ removal of 17.6 and 22.1 mg/g by untrea
Nerve reconstruction of extended nerve defect injuries still remains challenging with respect to therapeutic options.The gold standard in nerve surgery is the autologous nerve graft.Due to the limitation of adequate donor nerves, surgical alternatives are needed.Nerve grafts made out of either natural or artificial materials represent this alternat
An observation from practice is given tuberculous constrictive pericarditis, which has been occurring for a long time with symptoms of polyserositis without identifying of etiology.The recurrent course of the disease, the constant accumulation of effusion in the abdominal and pleural cavities was the basis 3m speedglas 9002nc for the diagnosis: "co
