Commercial vehicle tire of radial design with a tread with circumferential grooves formed to a profile depth, which divide the tread into at least two profile ribs () running in the central region of the tread with profile blocks () separated from one another by transverse grooves () and into shoulder-side profile ribs, wherein at least one of the circumferential grooves () adjoining a central profile rib () has, in cross section, a radially outer sipe-like narrow section () and a channel () adjoining this in the interior of the tread which is configured to be wider than the sipe-like narrow section () and which is delimited by two channel walls () and a channel bottom () forming the groove bottom, and wherein this circumferential groove () is interrupted in its course by entry points of transverse grooves (). Opposite the entry points, a projection (') is formed locally in each case on the channel wall () located opposite the entry points of the transverse grooves ().

Commercial vehicle tire

A pneumatic vehicle tire, in particular utility vehicle tire, having a tread which has a directional profiling with shoulder-side and middle profile ribs running in a circumferential direction, wherein at least one of the middle profile ribs (), which is in particular a profile rib running along the tire equator, is traversed in an axial direction by sipes () with a width (b) of 0.5 mm to 1.2 mm, each of which has a central portion (), in which the sipe () runs with an undulation in the direction of extent thereof, and two lateral portions (). The sipes () extend, in plan view, in an arc shape and symmetrically with respect to the centerline of the profile rib (), and, in the lateral portions () and in the central portion (), have a uniform undulation running in the radial direction, on which the undulation present in the extent direction of the sipes () is superposed only in the central portion () of the sipe ().

The invention relates to a method for producing micro-nano combined active systems in which nanoparticles of a first component are bonded to microparticles of a second component, comprising the following steps: (a) producing a low-ligand colloidal suspension containing nanoparticles of the first component, (b) adding microparticles to the colloidal suspension containing the nanoparticles or adding the colloidal suspension containing the nanoparticles to a dispersion containing the microparticles and intensively mixing so that the nanoparticles adsorb onto the microparticles, (c) separating the microparticles and the nanoparticles bonded thereto from the liquid and drying the microparticles and the nanoparticles bonded thereto.
