Abstract. To investigate the characteristics and changes in sources of carbonaceous aerosols northern Chinese cities after implementation Action Plan for Air Pollution Prevention Control 2013, we collected PM2.5 samples from three representative inland cities, i.e., Beijing (BJ), Xi'an (XA), Linfen (LF), January 2018 to April 2019. Elemental carbon (EC), organic (OC), levoglucosan, stable isoto...

Mobile agents are autonomous software entities driven by a set of goals and tasks. Reactivity, social ability, autonomy, the ability to move to different network locations, and the weak agent notion of proactiveness, allow for autonomous processing of distributed information according to their environment (context awareness). Although agent mobility has been devised for homogeneous environments...

Our studies examined the role of dopamine D4 receptors in the induction of behavioral sensitization to amphetamine (Amp) and accompanying neurochemical and molecular adaptive responses using a highly selective D4 antagonist, PNU-101387G. Behavioral sensitization to an acute challenge of Amp (2 mg/kg, s.c.) was observed in rats pretreated with five daily doses of Amp (2 mg/kg/d, s.c.) followed b...

Acetaminophen (APAP) overdose is the most frequent cause of drug-induced liver failure in the world. Hepatic c-jun NH2-terminal protein kinase (JNK) activation is thought to be a consequence of oxidative stress produced during APAP metabolism. Activation of JNK signals causes hepatocellular damage with necrotic and apoptotic cell death. Here we found that APAP caused a feedback increase in plas...

The new mineral species freitalite, C14H10, corresponding to the aromatic hydrocarbon anthracene, has been discovered on mine dump of Königin Carola shaft (also named Paul Berndt Mine), Freital, near Dresden, Saxony, Germany. forms thin blades or flakes irregular shape up a few millimetres in size and shows an intense violet whitish-violet white colour. Freitalite is product pyrolysis...

Two organic-inorganic hybrid materials, C6H4(NH3)2∙Cl2 (I) and β-[C6H10N2]2ZnCl4 (II), have been synthesized by hydrothermal method. These two materials are one of the emerged as most brilliant components classes. extraordinary compounds synergistically combine desired physical properties both organic inorganic into a single compound offering possibility to achieve great improvement over time i...

With millions of doses COVID-19 vaccine already administered, the world is beginning to sense a future without pandemic. But chemists will still feel its impact, at least start year, as they wait for economy recover prepandemic swagger. Meanwhile, expect see companies and regulators return their focus environmental issues such climate change, persistent pollutants, plastics recycling, clean ene...
