Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

The present disclosure relates to pillars useful in the fabrication of insulated glass units, particularly, vacuum glazing, insulated glass units. The invention also relates to insulated glass units containing said pillars. The present disclosure provides a pillar for use in a vacuum insulated glass unit wherein the pillar includes a body. The body includes a plurality of first structures, at least one first void region between the plurality of first structures; and a first land surface region located between the plurality of first structures and at least one first channel having first and second ends and a first channel opening proximate the first surface of the body. The first channel is in fluid communication with the local environment through at least one of its first and second ends, and the at least one first void region is in fluid communication with at least one of the local environment in a direction parallel to the first surface and the at least one first channel. The height of the plurality of first structures is less than the depth of the first channel.

Described herein is an improved abrasive material () in which the cutting performance is orientation-independent. The abrasive material () comprises an abrasive structure () including a plurality of elongate abrasive elements () aligned to be define a first open square. A plurality of pyramidal abrasive elements () arranged in a second open square are located within the first open square defined by the elongate elements ().
