Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction
Advanced Healthcare Materials, EarlyView.Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Saturn Systems Holddown Acoustic Efficiency and Normalized Acoustic Power Spectrum [PDF]
The Journal of the Acoustical Society of America, 1972 Saturn systems field acoustic data are used to derive mid- and farfield prediction parameters for rocket engine noise. The data were attained during Saturn vehicle launches at the Kennedy Space Flight Center. The data base is a sorted set of acoustic data measured during the period 1961 through 1971 for Saturn system launches SA-1 through AS-509.
