Close up, it saw tiny spheres embedded in the rocks, similar in appearance to iron-rich spheres nicknamed "blueberries" that the rover had observed earlier.
The mesophase transformation from cubic Im¯3m to Ia3d symmetries occurred when the concentration of cerium nitrate was increased from 0 1 mol% to 5 8 mol%; while higher ceria loadings resulted in the formation of phase segregated alumina-rich spheres embedded in a ceria-rich matrix.
In this work, polyethersulfone (PES) beads with diameter of around 2.5 mm, in which nanosized amine-rich polymer spheres (APSs) with particle size of ∼400 nm are immobilized, are fabricated via phase inversion route.
We herein report a confined growth strategy for the synthesis of a novel ZnO/carbon mesoporous composite that consists of small ZnO nanoparticles whose growth is confined in rationally designed N-rich carbon spheres (referred to as ZnO-NMPCS).
The N-rich carbon spheres (NRCS) possess high surface area, uniform mesoporous structure, and high level of N-doping, synergically enabling excellent lithium storage properties in terms of high capacity, fast rate capability and long cycling lifespan even at high current rate (638 mAh g−1 after 2000 cycles at 2 A g−1).
It was argued that this electronic difference may be caused by the amido-rich coordination sphere compared to 2-His-1-carboxylate enzymes.
Rubredoxins (Rds) and their derivatives have been extensively used, in the last few decades, in order to elucidate structure and functional aspects of metal sites involving rich sulphur coordination spheres.
Zhang and colleagues [8] used phosphate group to increase the content of oxygen-containing functional groups on the surface of phosphorus-rich hydrothermal carbon spheres.
Desserts include a dense, intensely caramel-flavored flan, sitting on a pool of syrup with two crisp wafers rising like antennae, and pumpkin fritters ($6.50), like golf ball-size spheres of rich pumpkin pie, coated with cinnamon and allspice.
The weak interaction triggers several topological defects that emerge as rich morphologies such as spheres, rods, fibers, and gyroids [15, 16].
In our previous study, rich antimony hollow Sb2Se3 sphere particles demonstrate an excellent catalytic property for the hydrogenation of p-nitrophenol [30, 31].
