Common applications include use as an electrode in electro discharge machining and as a mold material in metal casting. These applications often include fine details that are difficult to achieve with rotary tool machining techniques. Ablation with an Nd:YAG laser marking system permits greater detail in the machined pattern. The beam behavior and resultant mark are determined by four key operating parameters: lamp current, pulse frequency,...

Abate - The purpose of this experiment is to determine the susceptibility of propionibacterium acnes to photodynamic therapy (PDT). Propionibacterium acnes (P. acnes) is the leading cause of acne vulgaris—a chronic inflammatory skin disorder that affects an estimated 80% of Americans. Antibiotics are the primary means of acne treatment; however, the emergence of antibiotic resistant P. acnes has made it ineffective. PDT is an alternative form of treatment that excites P. acnes’ naturally produced photosensitizer, corporprophyrin III dihydrochloride (CIIID), and induces a cascade of events...
