CATALYTIC TEST PAPER PREPARED BY COMPOSITING METAL PARTICLE-EMBEDDED BACTERIAL CELLULOSE WITH PLANT FIBERS, AND METHOD THEREFOR

Disclosed is a catalytic test paper prepared by compositing metal particle-embedded bacterial cellulose with plant fibers, and a preparation method therefor. Hydroxyl groups of bacterial cellulose are bonded with a nitrogen-containing or phosphorus-containing organic small molecule compound. By means of a chelation between a nitrogen or phosphorus atom with a metal, transition metal ions are adsorbed to a nanoporous surface of bacterial cellulose, and the transition metal ions are reduced in situ to obtain bacterial cellulose embedded with metal nanoparticles. The bacterial cellulose is composited with the plant fiber, and the catalytic test paper is prepared by a papermaking method. The catalytic test paper has the advantages of convenient use and recovery, high reusability, simple design, low manufacturing cost, higher catalytic efficiency, a green degradable support material, etc.

High density renewable fuels from zizaenes

A process for making high density fuels having the potential to increase the range and/or loiter time of Navy platforms. Derivation of these fuels from a sustainable source will decrease the carbon footprint of the Department of Defense (DoD) and reduce reliance on nonsustainable petroleum sources. Fuels based on ziza-anes have volumetric net heats of combustion up to ca. 18% higher than conventional Navy jet fuel (JP-5). Moreover, ziza-anes can be generated from sustainable biomass sugars via fermentation.
