Abstract: The present invention provides a method for preparing a transparent free-standing titanium dioxide nanotube array film. In the method, with the titanium foil as a substrate, the titanium dioxide nanotube array film is obtained by anode oxidation on the surface of the titanium foil. Upon high temperature annealing, the titanium dioxide nanotube array film naturally falls off to obtain the transparent free-standing titanium dioxide nanotube array film. The method according to the present invention features simple operations, saves time and cost. With the method, a completely strippable titanium dioxide nanotube array film may be prepared, and in addition, morphology of the titanium dioxide nanotube is not damaged. The free-standing and complete titanium dioxide nanotube array film facilitates transfer and post-treatment, has the feature of transparency and may be in favor of the applications to the studies such as photocatalysis and the like.

Abstract: A predicting method of cell deconvolution based on a convolutional neural network is provided. The convolutional neural network technology is used to speculate the cell type composition proportion of a tissue from single-cell RNA sequencing data. Compared with a traditional cell deconvolution algorithm, the predicting method of cell deconvolution based on a convolutional neural network overcomes the defects that the traditional cell deconvolution algorithm needs to carry out complex data preprocessing and needs to design a mathematical algorithm to standardize the single-cell sequencing data. According to the convolutional neural network designed by the present disclosure, hidden features can be extracted from the single-cell RNA sequencing data, network nodes have very high robustness to noise and errors of the data, and internal relations among various genes are fully mined, so that the cell deconvolution performance is improved.

Abstract: A process for preparing a ketone or carboxylic acid by catalytic oxidation of a secondary or primary alcohol comprises adding the secondary or primary alcohol as a raw material and N-hydroxyphthalimide (NHPI) combined with phthalocyanine, serving as a catalytic system, into an amount of an organic solvent into which oxygen gas is then introduced, to proceed with an oxidation reaction to give the ketone or carboxylic acid. The oxygen gas is employed as the source of an oxidant. The oxidation reaction may be carried out under normal pressure at 60 to 120° C. for 9 to 36 hours. The process can produce a high yield of ketone or carboxylic acid. Compared with conventional technology, the process has several advantages, such as the green oxidant, the cheap catalyst which can also be easily prepared and separated, and mild reaction conditions, and it is also an environmentally friendly process for alcohol oxidation.
