Designing Hollow Nano Gold Golf Balls
Hollow/porous nanoparticles, including nanocarriers, nanoshells, and mesoporous materials have applications in catalysis, photonics, biosensing, and delivery of theranostic agents. Using a hierarchical template synthesis scheme, we have synthesized a nanocarrier mimicking a golf ball, consisting of (i) solid silica core with a pitted gold surface and (ii) a hollow/porous gold shell without sili...
متن کاملEye injury from exploding golf balls.
Golf balls with liquid centres are liable to explode if damaged, and thus present a potential hazard to the eye. This injury was described by Duke-Elder (I954) who concluded ". . . Fortunately this hazard has now been removed from golf". In the past 5 years, however, several cases have been reported in the American literature (Johnson and Zimmerman, I 965; Penner, I 966; Slusher, Jaegers, and A...
متن کاملOn Playing Golf with Two Balls
We analyze and solve a game in which a player chooses which of several Markov chains to advance, with the object of minimizing the expected time (or cost) for one of the chains to reach a target state. The solution entails computing (in polynomial time) a function γ—a variety of “Gittins index”—on the states of the individual chains, the minimization of which produces an optimal strategy. It tu...

متن کاملTrapping Iron Oxide into Hollow Gold Nanoparticles
Synthesis of the core/shell-structured Fe3O4/Au nanoparticles by trapping Fe3O4 inside hollow Au nanoparticles is described. The produced composite nanoparticles are strongly magnetic with their surface plasmon resonance peaks in the near infrared region (wavelength from 700 to 800 nm), combining desirable magnetic and plasmonic properties into one nanoparticle. They are particularly suitable f...
