The invention relates to a gas permeable membrane for the optical measurement of the partial pressure and/or the concentration of a gas species, the membrane comprises a porous light- transmissible membrane matrix containing a metal oxide wherein the membrane matrix is at least partially charged with at least one gas-selective compound whose optical characteristics change upon an interaction with a corresponding gas species. The average pore diameter of the pores of the membrane matrix ranges from 1 to 50 nanometers, the total pore volume from 1 to 30 mL/m2 and the metal oxide is pseudo-boehmite with the general formula AI 2 O 3 n * H 2 O, wherein n ranges from 1 to 1.5, or an alumina oligomer. Further, the invention relates to the use of the membrane for the measurement of the presence, the partial pressure and/or the concentration of a gas, for example in cultivation flasks and bags, in gas atmospheres, incubators, medical devices, solutions, vapors and exhaust gases. In another aspect, the invention provides a method for the manufacture of the membrane according to the invention.

Certain example embodiments of this invention relate to a window having anti-fungal/anti-bacterial properties and self-cleaning properties, and a method of making the same. In certain example embodiments, a silver based layer is be provide and the layer(s) located thereover (e.g., the zirconium oxide inclusive layer) are designed to permit silver particles to migrate/diffuse to the surface over time to kill bacteria/germs at the surface of the coated article thereby creating an anti-bacterial/anti-fungal effect. In certain example embodiments, silver may also or instead be mixed in with other material as the top layer of the anti-bacterial coating.

摘要:
A ceramic member in which the metal layers with high void ratio are sufficiently sintered to lower a residue of resin is produced. The method for manufacturing a ceramic member which comprises a step of forming a stacked compact from a plurality of metallic paste layers containing a metal component M 1 that are stacked one on another via ceramic green sheets, and a step of firing the stacked compact, wherein at least one of plural metallic paste layers is formed as a second metallic paste layer that has the mass percentage X higher than that of the metallic paste layer that adjoin therewith in the stacking direction and a ceramic powder is contained in the second metallic paste layer in the step of forming the stacked compact, the mass percentage X being the proportion of the metal component M 1 to the total metal content in the metallic paste layer.
摘要:
Combining good metal chassis and good synthetic resin structures, achieving mass production with high productivity, and enabling free design of shapes and structures, are all important considerations in electronic devices, household electric appliances and the like. Moreover, the need for components that are useful in reducing the weight and increasing the strength of various parts and structures is not restricted to electronic devices and household electric appliances. The surface of an aluminum alloy shaped product is covered with ultrafine recesses by being dipped in an eroding aqueous solution, or has formed thereon a metal oxide layer covered with the openings of ultrafine pores by anodizing. On the resin side, there is prepared a polyamide resin compounded with an impact resistance modifier, a mixture of an aliphatic polyamide and an aromatic polyamide, or a mixture of aromatic polyamides. The aluminum alloy shaped product is inserted into an injection mold, and a polyamide-type resin composition is injected onto the surface of the aluminum alloy shaped product, to manufacture an integrated composite.
摘要:
A light-weight composite material with enhanced structural characteristics includes, in one embodiment, a compositionally modulated nanolaminate coating electrically deposited into an open, accessible void structure of a porous substrate. As a result of including a nanolaminate within the void structure, the composite can include a greater amount of nanolaminate material per unit volume than can be achieved by depositing a nanolaminate material solely on a two- dimensional surface. In addition, the nanolaminate material as well as other material electrodeposited to form the composite is compositionally modulated so that discontinuities between layers are minimized and potentially eliminated. The light-weight but structurally enhanced composite material can be used in a number of different applications including, but not limited to, ballistic applications (e.g., armor panels or tank panels), automotive protection applications (e.g., car door panels, racing shells) and sporting equipment applications (e.g., golf club shafts and tennis racket frames).
