A solid-state fuel battery comprises an anode, a cathode spaced from the anode, and a solid-state electrolyte disposed between the anode and the cathode. A material of the solid-state electrolyte is a hydrogen-containing transition metal oxide having a structural formula of ABO.sub.xH.sub.y, wherein A is one or more of alkaline earth metal elements and rare-earth metal elements, B is one or more of transition metal elements, x is a numeric value in a range of 1 to 3, and y is a numeric value in a range of 0 to 2.5. A method for making the solid-state electrolyte for the solid-state fuel battery is further provided in the present disclosure.

The invention relates to cerium oxide particles having a roughness index RI of at least 5, to a making process thereof and to the use thereof in chemical mechanical polishing applications.

A carbonate production apparatus including a concentration unit that concentrates water to be treated containing carbon dioxide and alkaline earth metal ions by osmosis using a semi-permeable film, and a carbonate production method are provided. Accordingly, it is possible to produce a carbonate from a solution containing carbon dioxide and alkaline earth metal ions with less energy than concentration by heating and evaporation.

A water handling device comprising a water processing unit and an outer shell housing of vibration and/or pulsation damping material. The water handling device comprising opposed end plates including a water inlet connector, a water outlet connector, and a power connector. A circuit board extends between the opposed end plates and is connected thereto. An inner housing made of cured encapsulating material filling an interior volume defined by the outer shell housing and the end plates. The encapsulating material is hard or elastic relative to the soft outer shell housing. Vibration and/or pulsation damping elements protrude outwardly relative to the outer shell housing.

Provided is an aluminate fluorescent material having a composition represented by the formula X1.sub.aMg.sub.bMn.sub.cAl.sub.dO.sub.a+b+c+1.5d, in which X1 is at least one element selected from the group consisting of Ba, Sr; and Ca, a, b, c, and d satisfy 0.5a1.0, 0.0b<0.4, 0.3c0.7, 8.5d13.0, and 9.0b+c+d14.0.

A fluorescent member includes: a wavelength converter including an incidence part on which a light of a light source is incident and an output part from which a converted light subjected to wavelength conversion as a result of excitation by an incident light is output; and a reflecting part provided in at least a portion of a surface of the wavelength converter. The wavelength converter is comprised of a material whereby a degree of scattering of the light of the light source incident via the incidence part and traveling toward the output part is smaller than in the case of a polycrystalline material.

A zero-valent metal polymeric complex supporter (ZVM-PCS) is disclosed. PCS possesses porous surface and internal coralloid-like channel structure that can accommodate high amount of iron-containing materials and derivatives thereof. The surface pore size, porosity, hydrophilicity and internal coralloid-like channel structure of PCS can be tailored through the manufacturing process, with which PCS can be functioned as a regulator for the releasing of produced hydrogen, and also control the adsorption and reactions toward heavy metals and chlorinated volatile organic compounds in water. The released hydrogen from the ZVM-PCS can be applied to anaerobic bioremediation. Moreover, the ZVM-PCS can be developed as the filter materials that can be installed in a column or any storage for water and wastewater treatment, or even in a groundwater cut-off barrier for the cleanup of contamination. While the ZVM-PCS is synthesized as a film without openings, it can be used as the electromagnetic interference shielding material.
