Methods for fabricating final substrates for use in optics, electronics, or optoelectronics are described. In an embodiment, the method includes forming a zone of weakness beneath a surface of a source substrate to define a transfer layer, and forming a first bonding layer on the source substrate surface. A second bonding layer may be formed on a surface of an intermediate support, and the exposed surfaces of the first and second bonding layers joined to form a composite substrate. Next, the source substrate is detached from the composite substrate along the zone of weakness to expose a surface of the transfer layer, and a support material is deposited onto the exposed surface of the transfer layer. The transfer layer and support material are then separated from the composite substrate by elimination of at least the first bonding layer to form the final substrate. The zone of weakness may advantageously be formed by implanting atomic species into the source substrate.

The invention discloses a preparation method of a hydrogenation catalyst. The final catalyst is prepared by impregnation method or coprecipitation method using a carrier material containing molecular sieve and amorphous silica-alumina. The carrier material is prepared by introducing molecular sieve slurry in the process of forming amorphous silica-alumina gel, which improves the distribution of molecular sieve in the silica-alumina carrier, improves the coordinated catalytic effect of the two carrier materials, and greatly improves the performance of the catalyst. The catalyst prepared by the method of the present invention can be used in various hydrogenation processes.

The invention discloses a non-support three-dimensional printing method based on inclined layering. The method comprises five steps of model surface overhanging area identification, model reestablishment, horizontal slicing, motion code coordinate transformation, and path coupling; a path includes two parts: a horizontal layered path and an inclined layered path. A path track inclined relative to a horizontal plane is formed at an overhanging part; when the region is printed, a new layer of material can be guaranteed to be not only suffered from gravity but also is suffered from an adhesive force in a deposition process due to the presence of a formed printing layer on an upper layer. An additional supporting material is omitted, a printing raw material is saved, the printing efficiency is improved, and a process of subsequent support removal is omitted. The inclined layered three-dimensional printing path provided by the invention has a common code format, can be directly applied in commercial and open-source desktop type three-dimensional printers, has extensive application prospects, and can be extended to the three-dimensional printing technology in biology, chemical engineering, macromolecule and food industries.
