A polishing liquid containing abrasive grains, a hydroxy acid, a polyol, a cationic compound, and a liquid medium, in which a zeta potential of the abrasive grains is positive and a weight average molecular weight of the cationic compound is less than 1000.

A method for manufacturing a microfluidic device (100) includes depositing a bonding layer (106) on a surface of a second glass layer (104a) of a glass substrate having a first glass layer (102) and the second glass layer (104a) fused to the first glass layer (102), such that a masked region of the surface is covered by the bonding layer, and an exposed region of the surface is uncovered by the bonding layer; removing a portion of the second glass layer corresponding to the exposed region of the surface to form a flow channel (112) in the glass substrate; and bonding a cover (108) to the glass substrate with the bonding layer (106).

Deadfront articles that include a tactile element formed on a first surface of a substrate and a visual element disposed on a second surface of the substrate opposite the first surface. The tactile element is positioned on the first surface of the substrate in a complimentary fashion to the visual element disposed on the second surface of the substrate. The tactile element may include a surface roughness portion having a surface roughness different than the surface roughness of an area bordering the surface roughness portion. The deadfront articles may be incorporated into an automobile interior to provide a visual and haptic display interface for a user.

A glass sheet polishing assembly includes a support assembly having a mounting assembly disposed thereon. The mounting assembly interconnects the glass sheet and the support assembly in an operative position during a polishing procedure. A carriage is movable relative to the support assembly in a first direction relative to the glass sheet. A polishing assembly is movable along a length of the carriage in a second transverse direction. A drive assembly is disposed and structured to define a movable driving relation with the polishing assembly and the carriage to define a continuous path of travel of the polishing assembly over a surface of the glass sheet and to successively move both the carriage and the positioning assembly relative to the support assembly in the first direction and continuously move the polishing assembly along said carriage in the second transverse direction.
