Side chains are the necessary components for solution-processable semiconductors and exert significant influence on charge transport. In this work, a series of acceptor–donor–acceptor (A–D–A) small molecules (C1–C8) based...

This note contains a report of a proof by computer that the Fibonacci group F (2; 9) is automatic. The automatic structure can be used to solve the word problem in the group. Furthermore , it can be seen directly from the word-acceptor that the group generators have infinite order, which of course implies that the group itself is infinite.

Density functional theory calculations were used to systematically explore the effects of axial ligation by solvent molecules on reactivity and selectivity dirhodium tetracarboxylates with diazo compounds in context C–H insertion into propane. Insertions three types compounds?acceptor/acceptor, donor/acceptor, donor/donor?promoted tetraformate tested without for no surrounding solvent, dichloro...

We previously proposed that HIV-1 minus strand transfer occurs by an acceptor invasion-initiated multi-step mechanism. During synthesis of minus strong stop DNA, reverse transcriptase (RT) transiently pauses at the base of TAR before continuing synthesis. Pausing promotes RT-RNase H cleavage of the donor RNA, exposing regions of the cDNA. The acceptor RNA then invades at these locations to inte...
