Gas Chemical Nanosensors with Sensing Elements Based on Molybdenum, Iron, and Chromium Oxides
Аннотация
The results of the development of gas chemical nanosensors with sensing elements based on molybdenum oxide, iron oxides, and chromium oxide are presented in the review. The developed devices are systematized in accordance with the features of the construction of their sensing elements; the groups of nanosensors based on molybdenum oxide, iron oxides, and chromium oxide are divided each into three subgroups. The analytical capabilities of these devices are considered and the observable regularities are noted. In particular, the potential of nanosensors in identifying a large number of inorganic and organic chemical compounds is demonstrated. The effect of the morphology and composition of the coating and temperature of the sensing element on the sensitivity and selectivity of the measurements and the response and recovery times is shown.

Diverse Biologically Active Pyridazine Analogs: A Scaffold for the Highly Functionalized Heterocyclic Compounds
Аннотация
Nitrogen atom containing heterocycles showed diverse biological properties are important structural feature of many physiologically active compounds. Pyridazines and phthalazines hold considerable interest relative to the preparation of physiologically active compounds. The pyridazine compounds also show antifeeedant, insecticidal, herbicidal, molluscicidal, plant growth regulatory and other agrochemical activities. The various pyridazine drugs are selective PDE-III inhibitors possessed positive inotropic effect combined with vasodilation. These agents are effective in different cardiovascular diseases like acute and chronic heart failure, myocardial infarction, angina, arrhythmia, and hypertension. Pyridazines and phthalazines further focus our attention because of their easy functionalization at various ring positions, which makes them attractive synthetic compounds for designing and development of the novel pyridazines and phthalazines drugs in future. Various substituted pyridazine derivatives were also reported to show antibacterial, antifungal, and antiviral properties. We considered some compounds bearing pyridazine in their molecular framework.
