Abstract:
A passive photo-writing approach for optical data recording is described. Poly(N-vinyl-2-pyrrolidone) has been demonstrated as a photochemically deoxygenating polymeric matrix in which phosphorescent images from a molecular phosphor could be written by photo-activation and be competitively erased by diffusional oxygen quenching.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
