Cellulose as sacrificial agents for enhanced photoactivated hydrogen production

Simultaneous cellulose conversion and hydrogen production assisted by cellulose decomposition under UV-light photocatalysis.

Photocatalytic conversion of cellulose to sugars and carbon dioxide with simultaneous production of hydrogen assisted by cellulose decomposition under UV or solar light irradiation was achieved upon immobilization of cellulose onto a TiO2 photocatalyst. This approach enables production of hydrogen from water without using valuable sacrificial agents, and provides the possibility for recovering ...

Simulation of Enhanced Biomass Gasification for Hydrogen Production using iCON

Due to the environmental and price issues of current energy crisis, scientists and technologists around the globe are intensively searching for new environmentally less-impact form of clean energy that will reduce the high dependency on fossil fuel. Particularly hydrogen can be produced from biomass via thermochemical processes including pyrolysis and gasification due to the economic advantage ...

Enhanced aldolase activity and glycolysis as short term effects of hydrogen cyanide for the release of dormancy in walnut kernels

Seed dormancy removal by cold stratification is accompanied by the development of gluconeogenic competence. Although hydrogen cyanide can stimulate the germination of many herbaceous dormant seeds and increase gluconeogenesis in long term, its short-term effects on sugar metabolism require further investigation. Accordingly, an experiment in the form of complete randomized design was carried ou...

Vibrationally enhanced tunneling as a mechanism for enzymatic hydrogen transfer.

We present a theory of enzymatic hydrogen transfer in which hydrogen tunneling is mediated by thermal fluctuations of the enzyme's active site. These fluctuations greatly increase the tunneling rate by shortening the distance the hydrogen must tunnel. The average tunneling distance is shown to decrease when heavier isotopes are substituted for the hydrogen or when the temperature is increased, ...
