BB guns or non-powder guns created in the modern era are able to reach exceedingly fast velocities as a result of advances in compressed-gas technology. While missile penetrating trauma has been well documented in neurosurgical literature, penetrating intracranial injury secondary to non-powder guns, along with their associated complications and treatments, is not well described, and even less so in the pediatric population.

This paper presents the results of determining the coefficient of friction when cold plastic deformation by the method of cold ring upsetting with different lubricants. The ring upsetting process is performed with varying degrees of deformation with three lubricants used: industrial oil, cooking oil, and zinc sulfate powder. Based on the deformation and dimension change of the samples after the upsetting, the coefficient of friction was determined by correlation comparison with the friction calibration curve performed by Male and Cockcroft.

To decrease the band gap of TiO2 and enhance its photocatalytic performance, in this work, N-doped nanocrystalline TiO2 is synthesized successfully through a simple sol-gel synthesis process with dicyandiamide used as N source. The N-doped TiO2 photocatalysts have been characterized in detail by means of powder X-ray diffraction, Raman spectroscopy, infrared spectroscopy, UV-vis spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscope. The photocatalytic activities of N-doped TiO2 to different organic pollutants are significantly different.
