Image Processing Methods For Dual-Energy Contrast-Enhanced X-Ray Breast Imaging
… The development and evaluation of numerous silver based nanoparticles for DE imaging was explored and imaged. Silica-encapsulated silver nanoparticles, gold-silver alloy nanoparticles, an “all-in-one” silver sulfide nanoparticle, and silver telluride nanoparticles were imaged in phantoms and …

Effect of silver nanoparticles on planktonic and biofilm cell growth
Silver nanoparticles (Ag NPs) are one of the most widely used nanoparticles, most notably serving as an antimicrobial agent for sanitization and medical purposes. Despite of their widespread use, little was known about the environmental effect of silver nanoparticles. This research focused on the …

Evaluation of potential acid mine drainage: A case study of the Albert Silver Mine, Mpumalanga Province, South Africa
… mining produces mine wastes that contain sulfide minerals that have potential to produce acid mine drainage. Albert Silver Mine conducted mining of the silver-sulfide bearing ore from 1885 to 1914. However, at the time, little attention was being given to acid mine water generation. This …
