Results from an intercomparison of several currently used in-situ techniques for the measurement of atmospheric formaldehyde (CH2O) are presented. The measurements were carried out at Bresso, an urban site in the periphery of Milan (Italy) as part of the FORMAT-I field campaign. Eight instruments were employed by six independent research groups using four different techniques: Differential Opti...

Organic-inorganic hybrid materials provide a desirable platform for the development of novel functional materials. Here, we report one-pot synthesis mesoporous nanospheres by in-situ sol-gel condensation tetraethoxysilane around surfactant micelle-confined nano covalent organic polymer (nanoCOP) colloids. The containing nanoCOPs uniformly distributed in mesosilica network, inherited visible lig...

Polyaza-heterocycles show a plethora of biological properties and represent significant percentage clinically used drugs. However, the imizado[1,2-a]pyrimidine ring system needs more attention in terms pharmaceutical applications. Herein, we report sequence involving an aldolic condensation/bromination/Hantzsch reaction to construct series 2-alkenylimidazo[1,2-a]pyrimidines for exploring their ...

An efficient one pot coupling of aldehydes, dimedone, ammonium acetate and ethyl acetoacetate by using catalytic amount of enneamolybdomanganate(IV) is reported. Various polyhydroquinoline derivatives have been prepared in high yields and comparatively less reaction time.

Two gas-phase formaldehyde (HCHO) measurement techniques, a modified commercial wet-chemical instrument based on Hantzsch fluorimetry and a custombuilt instrument based on fiber laser-induced fluorescence (FILIF), were deployed at the atmospheric simulation chamber SAPHIR (Simulation of Atmospheric PHotochemistry In a large Reaction Chamber) to compare the instruments’ performances under a rang...
