Blunted Tungsten Tip Cleaning by Nitrogen Gas Etching at Room Temperature without Tip Heating and Cooling

For a long time, the ultra-sharp tips are used for high resolution microscope, such as scanning tunneling microscope (STM), atomic force microscope (ATM), field emission scanning electron microscope (FE-SEM). In addition, helium ion microscope (HIM), which has sub-nanometer imaging resolution, employs the tip as gas field ionization source (GFIS) in recent years. There are a lot of required vit...

Cotton bud and ear cleaning--a loose tip cotton bud?

Complications that arise from self-cleaning the external ear canal are common. This is a prospective study using standard questionnaire on the practice of ear cleaning in 50 subjects.

EYcacy of a contact lens cleaning device and its enhancement of the performance of contact lens care products

Background—Corneal infections due to contact lens contamination are risks associated with contact lens wear. Care systems which reduce these risks are desirable. Methods—This study evaluated a contact lens cleaning device using normal saline initially and then four contact lens solutions. Results—Using saline, six out of 10 tests resulted in complete removal of challenge organisms or showed red...
