Abstract Organonitrogen and organosulfur compounds are abundant in the natural environment. To understand biological redox pathways properly, it is important for learners to be able count oxidation number of organic carbons. However, process counting not always easy. In addition, organonitrogen molecules seldom studied. compensate these problems, this paper explores bond-dividing method, which ...

Organonitrates (ON) are important products of gas-phase oxidation of volatile organic compounds in the troposphere; some models predict, and laboratory studies show, the formation of large, multifunctional ON with vapor pressures low enough to partition to the particle phase. Organosulfates (OS) have also been recently detected in secondary organic aerosol. Despite their potential importance, O...
Initially transparent organic particulate matter (PM) can become shades of light-absorbing brown via atmospheric particle-phase chemical reactions. The production of nitrogen-containing compounds is one important pathway for browning. Semisolid or solid physical states of organic PM might, however, have sufficiently slow diffusion of reactant molecules to inhibit browning reactions. Herein, org...

The review summarizes different bioinformatics tools used in studying the degradation of various xenobiotic compounds. Databases and Pathway Prediction Systems are key involved biodegradation. Several bio-degradative databases including EAWAG-BBD (Biocatalysis/Biodegradation Database), Plastics Microbial Biodegradation Database, ONDB (Organonitrogen Degradation Food risk component database (Foo...
ترکیبات آروماتیک آزو بشدت رنگی و پایدارند از مواد اولیه ارزان قیمت تهیه می شوند. بهمین دلیل بیش از یک قرن مورد استفاده قرار می گیرند. واکنش محلول سرد آمین آروماتیک نوع اول در دمایc (0-5)در محلول آبی اسید (h2so4,hc) با سدیم نیتریت (nano2 ) موجب تبدیل آمین به نمک آرن دی آزونیم arn+2x- می شود، که ترکیباتی بسیار فعالند و بعنوان واسط در تهیه انواع متعددی از ساختمانهای آروماتیک عمل می کنند یونهای آر...
