    摘要： Provided is a method for producing a porous glass member whereby cracking during production is less likely to occur and a porous glass member having excellent alkali resistance can be produced. A method for producing a porous glass member includes the steps of: subjecting a glass base material containing, in terms of % by mole, 40 to 80% SiO2, over 0 to 40% B2O3, 0 to 20% Li2O, 0 to 20% Na2O, 0 to 20% K2O, over 0 to 2% P2O5, over 0 to 20% ZrO2, 0 to 10% Al2O3, and 0 to 20% RO (where R represents at least one selected from among Mg, Ca, Sr, and Ba) to thermal treatment to separate the glass base material into two phases; and removing one of the two phases with an acid.

    摘要： A multilayer coil component includes a multilayer body in which a plurality of insulating layers are stacked and inside of which a coil is provided, and first and second outer electrodes provided on surfaces of the multilayer body and electrically connected to the coil. The multilayer body has first and second end surfaces, first and second main surfaces, and first and second side surfaces. The first outer electrode extends from at least part of the first end surface of the multilayer body across part of the first main surface and the second outer electrode extends from at least part of the second end surface of the multilayer body across part of the first main surface. A transmission coefficient S21 is −1.0 dB or higher in a range from 1 GHz to 40 GHz and is −1.5 dB or higher in a range from 40 GHz to 60 GHz.

    摘要： A method for preparing an optically transparent, superomniphobic glass composition is described. In one aspect, the present disclosure provides a method for preparing a glass composition, including heating a borosilicate glass comprising 45-85 wt. % silicon oxide and 10-40 wt. % boron oxide to form a phase-separated glass comprising an interpenetrating network of silicon oxide domains and boron oxide domains. The method includes removing at least a portion of the boron oxide domains from the phase-separated glass and depositing a hydrophobic silane to provide a porous glass having a hydrophobic silane layer disposed on a portion of the surface thereof, a total pore volume of 15-50 vol. %, and an average pore diameter of 20-300 nm. The method includes, within at least a portion of the volume of the porous glass, forming an aerogel precursor, and converting at least a portion of the aerogel precursor to an aerogel.
