With the development in egocentric vision, skill measurement has been recently proposed as a novel topic in this emerging field. In this report, we record the the experimenter’s first-person videos in Wet labratories (wetlab), and measure his/her operative skills. Specifically, given the videos of expert and amateur, we analyze their head motions, hands motions, eye-hand coordinations and key-m...

In this study, wet-chemical process was performed to prepare nano-size hydroxyapatite (HA) powders (≈10 nm) by varying concentration (low, medium and high) of the starting solutions in order to increase the amount of as-dried HA powders with different process conditions. Particle sizes and density were analyzed and differential thermal analysis was used to determine the glass transition (Tg) an...

the solvent free route for the synthesis of diaryl sulfoxides from arenes and thionyl chloride in the presence of lewis acids such as aluminum chloride and ferric chloride on silica gel are described.

CuCe mixed oxide is one of the most studied catalytic systems for preferential CO oxidation (CO-PrOx) purification hydrogen-rich gas stream. In this study, a series ceria supports were prepared via citrates-hydrothermal route by altering synthesis parameters (concentration and temperature). The resulting used preparation mixed-oxide catalysts wet impregnation. Various physicochemical techniques...

an efficient synthesis route to 1,4-dihydropyrimidine derivatives from reaction of divergent aldehydes with ethylacetoacetate and urea under solvent-free conditions by zno nanoparticles as a relative in expansive, eco-friendly, easy available, non-volatile, non-explosion, thermally robust, recyclable and easy to handle catalyst at 90°c with excellent yields is described. unenhanced reaction tim...
