A number n is said to be economical if the prime power factori-sation of n can be written with no more digits than n itself. We show that under a plausible hypothesis, related to the twin prime conjecture, there are arbitrarily long sequences of consecutive economial numbers, and exhibit such a sequence of length 9.

To optimize pretreatment conditions, we evaluated oxalic acid loading rates, treatment temperatures and times in a 2(3) full factorial design. Response-surface analysis revealed an optimal oxalic acid pretreatment condition to release sugar from the cob of Zea...

A visible-light-promoted chloramination of olefins is reported. N-Chlorosulfonamides serve as both nitrogen and chlorine sources. These reactions provide a simple, efficient, regioselective, and atom-economical method for the preparation of vicinal haloamine derivatives under mild reaction conditions. A variety of olefins were tolerated, and chloramination products were obtained in good yields.
