The invention relates to a method for producing functionalised bimodal periodic mesoporous organosilicates (PMOs) by means of pseudomorphic transformation, to functionalised bimodal periodic mesoporous organosilicates (PMOs) that comprise at least one organosilicate and at least one functional component, and to the use of the PMO as a filter material, adsorption means, sensor material or carrier material for pharmaceutical products, insecticides or pesticides.

A process for forming a coating on a substrate comprises forming a non-fluorinated alkyl silane hydrolysate polymer and applying the non-fluorinated alkyl silane hydrolysate polymer to a surface of the substrate. The formed invisible-fingerprint coating can have an initial oil angle less than 50.

Disclosed herein is an optical fiber having an optically uniform coating having no physical defects in the coating greater than 100 micrometers in size over a length of 50 meters or greater.

A production method for a glass roll includes a start preparation step (S1) of feeding-out a first lead film (LF1) coupled to a starting end portion (GFa) of a first glass film (GF1) from an unwinding device (3) and allowing a winding device (8) to wind the first lead film (LF1 after passing of the first lead film (LF1) through a thermal film-forming device (4),). The start preparation step (S1) includes a temperature increasing step of causing the thermal film-forming device (4) to be increased in temperature to a film-forming temperature. The first glass film (GF1) reaches the thermal film-forming device (4) before the thermal film-forming device (4) is increased in temperature to the film-forming temperature.

A chucking apparatus and methods for coating a glass substrate using a vacuum deposition process are disclosed. In one or more embodiments, the chucking apparatus includes an ESC (ESC), a carrier disposed on the ESC, wherein the carrier comprises a first surface adjacent to the ESC and an opposing second surface for forming a Van der Waals bond with a third surface of a glass substrate, without application of a mechanical force on a fourth surface of the glass substrate opposing the third surface. In one or more embodiments, the method includes disposing a carrier and a glass substrate on an ESC, such that the carrier is between the glass substrate and the ESC to form a chucking assembly, forming a Van der Waals bond between the carrier and the glass substrate, and vacuum depositing a coating on the glass substrate.

A coating composition includes phosphorus pentoxide (P2O5), aluminum oxide (Al2O3), boron trioxide (B2O3), zinc oxide (ZnO), I group-based metal oxide, and II group-based metal oxide. The coating composition includes by weight based on a total weight of the coating composition 35 to 55% P.sub.2O.sub.5, 5 to 35% Al.sub.2O.sub.3, 5 to 40% I group-based metal oxide, 5 to 10% B.sub.2O.sub.3, 1 to 5% ZnO, and 1 to 10% II group-based metal oxide.
