Nitrous oxide

specific binding between receptors on the gate surface and target analytes to an electrical signal for low-cost, rapid, and sensitive detection, for which signal acquisition and processing units can be simply integrated. Although silicon based metal oxide FETs (MOSFETs) (planar or nanowire) [45,46], carbon nanotube based FETs and graphene based FETs [47-49] have been widely studied as candidates for advanced biosensing applications, they are somewhat limited in various facets. In the first section

The process of winemaking is one of the most complex and detailed processes, where every step is meticulous towards ensuring the best quality wine is produced. However, different phenomena are able to affect the wine even after it is bottled and stored. Oxidation is the chemical process

The disposal of colored organic waste water from the textile industries causes serious problems to the aquatic ecosystem and because of this the aquatic environment is contaminated which created a serious threat to the living organisms. Textile industry is water-intensive resulting a large amount of harmful dye effluent 33. The increasing awareness on environment issues the norms are being specified by the governments of various countries 34. In view of complex chemical, molecular structures and

Group 14 of the periodic table contains a mixture of non-metals (carbon and silicon), a metalloid (germanium), and two metals ( tin and lead). Tin is able to form dihalides and tetrahalides such as SnI2 and SnI4. However, lead will not form tetrahalides as readily as tin3. The tetrahalides of lead will decompose into dihalides due to their instability 3. The stability of the compounds is based on their respective oxidation states. Periodic trends suggest that group 14 oxidation states are normally

Ever wonder what invention can be made that will benefit the present and the future. Yet, it is not any ordinary invention, it is an invention that will make the planet greener and provide a healthier lifestyle for the people. These green developments are what are called sustainable chemistry. It is a tactic created to provide the needs of the present generations that will later also benefit the future generations. The people have to create greener solutions to many of these environmental problems

Study of the oxidation of 3,5-di-tert-butylcatechol with molecular oxygen catalyzed by of 5, 10, 15, 20-tetraphenylporphyrinatocobalt(II). M. Hassanein, S. El-Khalafy*, S. Shendy Tanta University, Faculty of Science, Department of Chemistry, Tanta 31527, Egypt. Abstract 5, 10, 15, 20-tetraphenylporphyrinatocobalt(II) showed good catalytic activity towards oxidation of 3,5-di-tert-butylcatechol to 3,5-di-tert-butyl-benzoquinone by dioxygen in dimethylformamide. The oxidation reaction was followed

calculate the enthalpy of formation for magnesium oxide. This was accomplished, first by finding the temperature change through use of a temperature probe within a chemical reaction with magnesium and hydrochloric acid, along with a chemical reaction containing magnesium oxide and hydrochloric acid. For the reaction that consisted of magnesium and hydrochloric acid, the temperature change was much more rapid compared to the reaction between magnesium oxide and hydrochloric acid. The reaction was gray

Empirical Formula and Percent Composition of Magnesium Oxide Prediction Magnesium oxide is an ionic compound (metal cation bonded to non-metal anion); therefore, we can determine its formula using the ionic charges of magnesium (Mg2+), and oxygen (O2-). To comply with the octet rule, the elements combine at a ratio of 1:1;as a result, the formula is MgO (s) . We can theoretically predict the empirical formula, and the percent composition, through this procedure: 1) Two moles of magnesium combines
