A method of detaching a thin film from a source substrate comprises the following steps: implanting ions or gaseous species in the source substrate so as to form therein a buried zone weakened by the presence of defects; splitting in the weakened zone leading to the detachment of the thin film from the source substrate. Two species are implanted of which one is adapted to form defects and the other is adapted to occupy those defects, the detachment being made at a temperature lower than that for which detachment could be obtained with solely the dose of the first species.

The present invention relates to an improved exhaust gas cleaning system and method for a combustion source comprising a hydrogen generation system, a sulfur oxides trap, and a nitrogen storage reduction (NSR) catalyst trap. The improved exhaust gas cleaning system and method of the present invention also provides for a water-gas-shift catalyst between the sulfur oxides trap and the NSR catalyst trap, and a clean-up catalyst downstream of the NSR catalyst trap. The invention provides also a sulfur trap regenerable at moderate temperatures with rich pulses, rather than at high temperatures. The improved exhaust gas cleaning system of the present invention provides for the sulfur released from the sulfur trap to pass through the nitrogen oxide trap with no or little poisoning of NO_x storage and reduction sites, which significantly improves NSR catalyst trap lifetime and performance to meet future emissions standards. The disclosed exhaust gas cleaning systems are suitable for use in internal combustion engines (e.g., diesel, gasoline, CNG) which operate with lean air/fuel ratios over most of the operating period.

The invention pertains to a water dispersible, preferably a powder composition of water extractible bioactive components of exclusively fruit or vegetable or plant origin. These components are obtainable by: a) subjecting a selected fruit or vegetable or plant material to homogenisation in weak alkaline conditions and at moderate temperature; b) separating the liquid extract from the homogenised mass and subsequently bringing it to neutrality; and c) eventually concentrating or drying, preferably by freeze drying, the neutralized liquid extract. The composition can be used as primary composition in the preparation of a food product for oral administration, a food supplement, a pet food product, a pet food supplement, a cosmetic preparation or a pharmaceutical preparation.

An electrolytic apparatus for using catalyst-coated hollow microspheres to produce gases, store them, and to make them available for later use. The apparatus uses catalyst-coated hollow microspheres in reversible electrochemical processes and reactions, such as those used in conjunction with water dissociation, fuel cells, and rechargeable batteries. The apparatus can be used to manufacture and store hydrogen and or oxygen and to make them available for subsequent use as raw materials for use in electrochemical and chemical reactions or as a fuel and or oxidizer for a combustion engine. The apparatus can be used as a hydrogen-oxygen hermetically seal secondary battery. The apparatus can be used as a hydrogen storage portion of certain types of secondary batteries. Hydrogen and oxygen can be stored within hollow microspheres at moderate temperature and pressure, eliminating the need for expensive storage and handling equipment, and increasing the mobility of hydrogen-powered vehicles. Storage of hydrogen and or oxygen within the microspheres significantly reduces flammability and explosion concerns and resolves many fuel cell scalability issues.

Granules of graphene oxide may be produced from a dispersion of nanoscale graphene oxide sheets by a spray drying method. Such granules have a three-dimensional corrugated morphology. The complexity of the corrugations, and the size distribution of the granules can be varied through selection of the spray-drying equipment used, and variation of the composition of the dispersion and the spray-drying parameters. Structural modifiers may be included in the graphene oxide dispersion to control the ultimate morphology of the granules. The granules of graphene oxide may be thermally reduced at a moderate temperature of 220° C. to increase the granules' electrical conductivity. The reduced granules may be used to fabricate electrodes for supercapacitors. The power and energy density of such an electrode material is comparable to those of conventional/commercial activated carbon-based electrodes.
