Abstract: The invention relates to a method for asynchronous communication by means of an internet platform (2), wherein registered users of the internet platform (2) can receive mail by means of the internet platform (2), wherein the mail is transmitted for at least part of the postal path thereof in electronic form by means of the internet and the internet platform (2), and further relates to an internet platform (2). In order to provide the users (N) expanded communication capabilities and a greater level of comfort, according to the invention, one of a plurality of presettable transmission paths is preset by the users (N) on the internet platform (2), said paths including the transmission of the mail as a letter, as a fax, and as electronic mail, and the transmission of the mail to the users (N) is performed or initiated by the internet platform (2) according to each preset transmission path.

Abstract: A process for synthesizing nanoparticles, in particular metal salt nanoparticles. To the synthesis mixture is added a modifying reagent which binds, by means of a first functional group, to the nanoparticle surface and which carries a second functional group for binding to molecules which are specifically selected in dependence on the subsequent use of the nanoparticles. This dispenses with a postsynthetic, separate, application-specific modification step. A new substance class, the pentaalkyl iminobis(methylenephosphono)carboxylates, are particularly suitable for this purpose.
