    “…We have studied femtosecond ablation of soda–lime glass sample under thin water film, under KOH and NaCl aqueous solutions films and their influence and benefits compared with ablation in the air atmosphere. These have been studied in case of the groove ablation using the infrared (IR) femtosecond laser. …”

    “…On the basis of the Reynolds stress model (RSM), a new two-stage cyclone separation device is modeled and the model is simulated under six kinds of air volumetric flow rate conditions. The two-stage cyclone separator was then tested in the laboratory and the experimental data were compared with the simulation data. …”

    “…[Image: see text] A green chemical method for mild oxidation of 1,2,3,4-tetrahydroisoquinolines (THIQs) and 3,4-dihydroisoquinolines (DHIQs) has been developed using air (O(2)) as a clean oxidant. DHIQs and THIQs could be efficiently oxidized to isoquinolines in dimethyl sulfoxide at 25 °C under an open air atmosphere with CuBr(2) (20 mol %) as the catalyst; different bases [NaOEt and/or 1,8-diazabicyclo[5,4,0]undec-7-ene] were used for the reaction according to the patterns of substituents (R(1), R(2)).…”
