A new method for producing silicon carbide platelets with low cost and high yield was introduced. The silicon carbide platelets were synthesized by powder-heating techniques with carbon black and SiO2 powder as raw materials and CoCl2 as catalyst. The starting mixtures were heated at a temperature in the range of 1800-2000°C for the duration of about 2-4h to produce substantially completely unagglomerated silicon carbide platelets with a thickness of 5-20μm and the average diameter of 50-200μm. Compared to the conventional heating, the powder-heating technique is advantageous of less investment on equipment, easy to manufacture and convenient to operate. Furthermore, it is very suitable for realizing the scaled production because of the lower synthesizing temperature, shorter reaction time and greater output.

Young Researchers

Although reaction time is one of the most common measures of neurological function, protocols often do not take into consideration many of the extraneous factors that may invalidate such assessments. This paper discusses several issues related to matters of instrumentation, subject control, design of assessment, and interpretation. Twenty recommendations are provided as a guideline for those who assess reaction time of clients or patients. While these suggestions are not proposed as definitive or complete, the points should serve as a guide to young researchers as well as a checklist for more seasoned experimenters.

One Pot Synthesis

We have developed a new method for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones in good to excellent yields via phosphomolybdic acid (PMA)-catalyzed cyclocondensation of 2- aminobenzamides with aldehydes or ketones in N,N-dimethylformamide (DMF) at room temperature. The present method proves to be efficient in terms of short reaction time, high yield, simple workup and easy purification.
