A photocatalyst can be regenerated with increasing efficiency, turnover number and turnover frequency in the presence of air by irradiating the photocatalyst with a first range of wavelengths of light that excite the photocatalyst to an intermediate and irradiating the intermediate with a second range of wavelengths of light that turns the intermediate to the photocatalyst.

An encoding/decoding apparatus and method using a low-density parity-check code (LDPC code) is disclosed. Basic column group information, serving as a set of information regarding positions of rows with weight 1, is extracted from a reference column in each column group of a predetermined parity-check matrix. Column group information transforms the positions of rows with weight 1 into positions whose lengths are within a required parity length. A parity-check matrix is generated according to the generated column group information. Data is enclosed or decoded based on the generated parity-check matrix.

The present invention relates to plant based materials, methods for their manufacture and biomaterials incorporating plant based materials.
