Cellulose is a kind of saccharide that is the main component in cell walls of plants and therefore is the organic compound that exists in the largest amount in nature. The purpose of this experiment is to convert cellulose to a fuel. Radio frequency (RF) in-liquid plasma is generated in a cellulose distributed solution and a glucose solution, and the generation gas rate is measured. While hydrogen is the main gas generated by the plasma breakdown, carbon monoxide, carbon dioxide, and low-grade flammable gases are also produced. In the glucose water solution or the glucose distributed solution, the solution itself evaporates and decomposes inside the plasma but since the saccharides are non-volatile, they cannot penetrate into the plasma and are not decomposition. However, when the cellulose is at concentrations of 30 wt% or more, it becomes granular and can directly enter the plasma as a solid, where the plasma decomposes the cellulose itself, significantly increasing the amount of gas generated. In addition, the spectrometry of the plasma emission shows the solution after the creation of plasma has the ability to absorb ultraviolet light.

Selenium has been found to be an excellent catalyst for the reductive debromination of some organic bromides with carbon monoxide and water: vic-dibromoalkanes and a-halo ketones can be reduced to the corresponding alkenes and ketones respectively in moderate to high yields.

A high performance antimicrobial paper was fabricated using composite of sugar cane bagasse pith and burned scallop particles with sugar cane bagasse pulp. The paper that was fabricated without degassing the composite pith had higher the scallop particle concentration on the top of surface displayed a greater value of anti-bacterial activity against methicillin-resistant Staphylococcus aureus than paper prepared that were mixed with degassing the composite pith and only mixed with scallop particle after 30minutes of cultivation. However the bagasse pulp and pith had antimicrobial activity as well as the scallop particle, the activity was not constant. The paper that was fabricated without degassing the composite pith had the stable activity and the quick effect.

The 7-membered ring compounds, (thujic acid, P-thujaplicin (hinokitiol), nezukone, ythujaplicin and methyl thujate) distilled from Western Red Cedar (WRC) by high-pressure steam distillation method have antibacterial and antifungal activities. In our present study, we attempted to find a way to provide antbacterial and antifungal functions to the fabrics of paper fibers made of cellulose. Attention was focused on the bonding of thujic acid and P-thujaplicin with cellulose, and increase the yield of the compounds by adding auxiliary agents or metal ions. It was revealed that the hydroxyl group of P-thujaplicin reacted not only as carboxylic acid but also as phenol. That characteristic could be attributed to the molecular structure of the hydroxyl group resonating to the carbonyl group of P-thujaplicin. This reaction was verified by a model experiment. The quantity of those compounds which combined with the fabrics of paper fibers was determined by GC-MS. It was verified that the fabrics of the paper fibers possessed antibacterial and antifungal functions and that these functions remained even after machine-washing.
