Solid State Gas Sensors: State of the Art and Future Activities
نویسندگان
چکیده
This paper gives an overview about the principles and the technologies used in solid-state gas sensors. These devices work by measuring a physical property changed by adsorption/desorption processes and chemical reactions on the surface of a sensing element, i.e. a solid-state film of a gas-sensitive material. Some of the most used types of solid state gas sensors are here described together with novel sensor technologies in development for commercial exploitation in the future.

متن کاملBioconversion and Enzymatic Activities of Neurospora Sitophila Grown Under Solid State and Submerged Fermentation on Sago Hamps (RESEARCH NOTE)
N.sitophila was grown under controlled conditions of solid state and submerged fermentation on Sago hampas. The optimum conditions of protein enrichment previously established for sugar beet pulp was used for this study. Under this condition the protein content of Sago hampas under solid state increased from 1.4 to 14.45% (W/W) whereas for Sago hampas and Sago starch, the protein content under ...
متن کاملRecent Advances in Hydraulic Fracturing for Enhanced Well Productivity: State of the Art Report
Hydraulic fracturing of horizontal wells is considered as the main reason for the phenomenal increase in production of oil and gas from marginal and unconventional reservoirs in North America. The process evolution started more than a decade ago and has resulted in ultra-low permeability reservoirs producing at close to the same rates as some of the very prolific reservoirs in the Middle East,...
متن کاملI-4: Male Fertility Preservation Options, Current State-of-The ART and Future Implications
Background Male infertility management has made significant progress during the past three decades, especially after the introduction of intracytoplasmic sperm injection (ICSI) in 1992. However, many boys and men still suffer from primary testicular failure due to acquired or genetic causes. New and novel treatments are needed to address these issues. Spermatogenesis originates from spermatogon...
متن کاملApplication of the Triangular Model in quantifying landfill gas emission from municipal solid wastes
Municipal solid waste landfills are significant parts of anthropogenic greenhouse gas emissions. The emission of significant amount of landfill gas has generated considerable interest in quantifying such emissions. The chemical composition of the organic constituents and potential amount of landfill gas that can be derived from the waste were determined. The chemical formulae for the rapidly bi...
