The silver knife surface is likely more chemically heterogeneous due to the Ag Cu alloy composition and likely has existing oxides or residues present from handling and previous treatments.
The dark area at the top of the gray scale image is due to the curvature of the knife blade, causing the knife surface to be out of focus with the XPS detector.
Time-delayed integration is used to increase SNR, reduce lighting irregularities at the knife surface, and collect an increased number of scattered photons.
Reports about the knife surfaced just as a popular new FX cable television drama series, "The People v. O.J. Simpson," chronicling the trial, is airing.
Five pieces of wood, approximately 2 × 5 mm, were cut from the canker margin with a flame-sterilized knife, surface-sterilized in 0.6 % sodium hypochlorite (pH adjusted to 7.2) for 30 s, rinsed twice in sterile distilled water for 30 s, and plated on potato dextrose agar (PDA, Difco, Detroit, MI) amended with tetracycline (1 mg/L).
This method is based on low temperature ion nitriding, when effects of the modification are intensified with deposition of hard films on pre-nitrided knives' surfaces.
Briefly, 73 samples were collected from working surfaces and cutting tools (swabs from knife, belt surface, and meat mincer) from slaughtering areas (10 samples), processing areas (19 samples), and points of sale (12 samples) and from workers' hands (20 samples) and workers' toilets (12 samples).
Here, slicing up through the text like a knife blade, surfaces a statement to match Austen's own scalpel-wielding.
As I sat on the beach in the evening, watching the sun slide down the dusky sky, a dorsal fin knifed the surface seven metres out: a reef shark scoping the shallows.
Furthermore, eighteen isolates were obtained from different environmental samples from slaughter line and quartering plant (knives and surface of tables) (5.63%) and three isolates at the quartering plant samples (ham, shoulder and loin) (3.75%).
The datasets shown were milled in from a glass knife-trimmed surface, but it is relatively straightforward to excavate anywhere from an edge cut into a trimmed block surface, though navigation may be cumbersome without a good surface map from a TEM.
