A method of treating a sensor array including a plurality of sensors and an isolation structure, where a sensor of the plurality of sensors has a sensor pad exposed at a surface of the sensor array and the isolation structure is disposed between the sensor pad and sensor pads of other sensors of the plurality of sensors, comprises exposing the sensor pad and the isolation structure to a non-aqueous organo-silicon solution including an organo-silicon compound and a first non-aqueous carrier; applying an acid solution including an organic acid and a second non-aqueous carrier to the sensor pad; and rinsing the acid solution from the sensor pad and the isolation structure.

A laundry treatment composition comprising: i) at least 5 wt % amphiphilic material, preferably selected from the group consisting of detersive surfactants and quaternary ammonium compounds, ii) from 0.1 to 5 wt % perfume, iii) 0.2 to 6 wt % of porous microparticles comprising sol-gel derived material, the sol-gel derived material including a plurality of alkylsiloxy substituents and wherein the sol-gel derived material is obtained from: (a) at least one first alkoxysilane precursor having the formula: (RO).sub.3Si(CH.sub.2).sub.nAr(CH.sub.2).sub.mSi(OR).sub.3 (1) where n and m are individually an integer from 1 to 8, Ar is a single-, fused-, or poly-aromatic ring, and each R is independently a C.sub.1 to C.sub.5 alkyl group and (b) optionally, at least one second precursor having the formula: (formula) (2) where x is 1, 2, 3 or 4; y is 0, 1, 2, 3; z is 0, 1; the total of x+y+z is 4; each R is independently an organic functional group; each an R is independently a C.sub.1 to C.sub.5 alkyl group and R is an organic bridging group, where the sol-gel derived material is swellable to at least 2.5 times its dry mass, when placed in excess acetone, whereby the weight amount of iii) exceeds the weight amount of ii) in the composition. Also, a method of prolongation of perfume delivery from a liquid laundry treatment composition comprising perfume, the method comprising the steps of: (i) adding sol-gel derived silica microparticles as described above to the liquid composition; C30068 EP (C) CPL (ii) optionally, diluting the liquid and applying the liquid or the diluted liquid to a surface to be treated to deposit the microparticles onto the surface; (iii) rinsing away the liquid or diluted liquid to leave perfume loaded microparticles on the surface to be treated; and (iv) releasing perfume from the microparticles over period of about 24 hours.

In a method of cleaning a substrate, a solution including a size-modification material is applied on a substrate, on which particles to be removed are disposed. Size-modified particles having larger size than the particles are generated, from the particles and the size-modification material. The size-modified particles are removed from the substrate.

A sensor array includes a plurality of sensors. A sensor of the plurality of sensors has a sensor pad exposed at a surface of the sensor array. A method of treating the sensor array includes exposing at least the sensor pad to a wash solution including sulfonic acid and an organic solvent and rinsing the wash solution from the sensor pad.

The present disclosure generally relates to a method for preparing a powder or granular foam control compositions and methods for reducing or preventing or breaking foam in various applications such as powder detergents as well as coatings, cementing, concrete, gypsum board and other construction type applications or in some agricultural formulations like fertilizers, herbicides and pesticides.

A foam control composition includes a component (A) and a component (B). Component (A) includes units of the formula (R.sup.1O).sub.a(R.sup.2O).sub.b(R.sup.3O).sub.cR.sup.4.sub.dR.sup.5.sub.eR.sup.6.sub.fSiO[SiR.sup.7R.sup.8O].sub.x[SiR.sup.9(OR.sup.10)O].sub.ySi(R.sup.1O).sub.a(R.sup.2O).sub.b(R.sup.3O).sub.cR.sup.4.sub.dR.sup.5.sub.eR.sup.6.sub.f.
