Enhanced Synthesis of Carbon Nanomaterials Using Acoustically Excited Methane Diffusion Flames.

Acoustically modulated methane jet diffusion flames were used to enhance carbon nanostructure synthesis. A catalytic nickel substrate was employed to collect the deposit materials at sampling position = 10 mm above the burner exit. The fabrication of carbon nano-onions (CNOs) and carbon nanotubes (CNTs) was significantly enhanced by acoustic excitation at frequencies near the natural flickering frequency (ƒ = 20 Hz) and near the acoustically resonant frequency (ƒ = 90 Hz), respectively.

[Application of modified plaster material and device in acupoint plaster therapy].

Through the analysis on the methods of medicinal paste preparation, the irritation of skin to medicine and the plaster materials adopted in acupoint plaster therapy for the prevention of winter-attacked disease in summer, the acupoint plaster materials and devices were improved. According to the differences in age, illness condition, acupoint and medicinal irritation of patients, the high-dosage, moderate-dosage and low-dosage series of medicine were prepared in proportion; 2. 5 mL and 5 mL syringes were manually reconstructed as the pushers for the delivery of the medicine paste of different specifications.
