about preparation and characterization of high temperature oxygen sensing composite material consisting of Gadolinium doped Ceria (GDC) together with a relatively low temperature melting‚ ionic conducting glass to facilitate lower sintering and operating temperature. This paper reports the physical and ionic conductivity properties of this sintered composite as a function of operating temperature. Keywords—Gadolinium doped Ceria‚ oxygen sensor‚ composite‚ glass‚ ionic conductivity I. INTRODUCTION

impacts to the human body. The first one is Nitrogen oxides (NOx). When the fuels are burning at a very high temperature combined with the electric sparks in the vehicles causing the nitrogen and oxygen in the atmosphere combined together but then the formation of nitrogen oxide will react with the oxygen to form nitrogen dioxide(NO2) rapidly. If people inhaled a low level of NO2‚ the gas will irritate your eyes‚ nose‚ throat‚ and lungs‚ possibly causing you to cough‚ tiredness‚ and nausea since NO2

Carbon Dioxide‚ Water Vapour‚ Nitrogen‚ Ammonia‚ Hydrogen Chloride‚ Sulphur Dioxide‚ Hydrogen and the Noble gasses. There was no oxygen at this time. Oxygen only appeared in the atmosphere around 3500 million years ago when the first simple organisms began releasing it. Most of the Earth’s atmosphere (78.08%) now is made up of Nitrogen. Another 20.95% is mage up of Oxygen. A number of other gases‚ including Argon and Carbon Dioxide‚ are present in trace amounts. The Carbon Dioxide levels in the atmosphere

called photosynthesis occurs in the chloroplast of the plant cell. During this process‚ oxygen (O2) is created as a waste product and is released into the air for us to breath. The formula for photosynthesis is: (reactants) (products) CO2 + H2O + sunlight ----> C6H12O6 + O2 This formula says that carbon dioxide + water molecules are combined with the energy from sunlight to produce sugar and oxygen. The reactants in photosynthesis (what is used) are CO2‚ water and sun. The plant gets water

Investigating the Effect of Concentration on the Rate of Enzyme Catalysed Reaction To investigate the effect of concentration on the rate of enzyme catalysed reaction I must know all the factors that affect it in order to investigate in this. Here are all the factors: Temperature- Enzyme like it warm but not too hot. Enzymes are biological catalysts‚ which speed up chemical reactions. They work most efficiently at the optimum point (37°C). If they are below 37°C they will work

using strong stretching and contracting muscles this is how it moves. It has other important functions such as how it in gets it oxygen this is how‚ the earthworms respire through their skin‚ and therefore require humid conditions to prevent drying out. They coat themselves in mucus to allow the passage of dissolved oxygen into their bloodstream. The earth transports oxygen and carbon dioxide through the earthworm’s skin by diffusion. For diffusion to occur‚ the earthworm’s skin must be kept moist or

and another Cyril West were appointed to study ways to improve fruit storage. Applying information obtained while studying seed germination‚ Kidd and West demonstrated that fruit ripening could be retarded by increasing carbon dioxide and lowering oxygen in the storage atmosphere. And‚ from that day onwards and still ongoing‚ constant efforts are being made to control the atmosphere surrounding commodities and fruit‚ to help improve business logistics and better serve the customer.

interferes with cellular respiration. If inhaled‚ Hydrogen Sulphide combines with haemoglobin in the bodies of human beings and other mammals. haemoglobin is the substance in blood which carries oxygen to tissues. In combining with the haemoglobin‚ hydrogen sulphide prevents the transportation of oxygen. Without oxygen‚ people cannot live. Although hydrogen sulphide is very foul smelling‚ it can quickly paralyse the sense of smell‚ overcome the victim‚ and cause death.It also causes irritation of mucous

technique to access the internal body. One type of nanorobot which can be used is the respirocytes.The respirocytes are artificial mechanical red blood cells designed by Robert.A.Fretias. It is a 1000 atm diamondoid pressure vessel designed to deliver oxygen about 236 times more than the natural blood cells per unit cell volume. These respirocytes are provided with mechanical‚ chemical and pressure sensors and are implanted with an onboard microcomputer. The processor can be remotely controlled by the

could exert its toxicity through intracellular generation of reactive oxygen species (ROS). Tellurite inhibits the cellular response to oxidative stresses. To inhibit the growth of most normal bacterial inhabitants of the upper respiratory tract‚ including most species of Streptococcus and Staphylococcus‚ is to inhibit the growth of aerobic organisms through the presence of oxygen and high concentration of tellurite.
