A core-shell structured mesoporous silica nanosphere with antagonistic acid and basic sites spatially isolated and designated diffusion path was fabricated and served as an efficient acid-base bifunctional catalyst for one-pot cascade reaction sequences with excellent activity and selectivity.

An electrochemical method is developed to quantitatively modify and spectroscopically monitor the size and shape of Ag nanotriangles fabricated by nanosphere lithography (NSL) on an indium tin oxide (ITO) electrode surface. AFM and SEM results demonstrate that the preferential order of electrochemical oxidation for a nanotriangle is, surprisingly, bottom edges first, then triangular tips, then ...

BACKGROUND This work focuses on the development of atorvastatin utilizing zein, a natural, safe, and biocompatible polymer, as a nanosized formulation in order to overcome the poor oral bioavailability (12%) of the drug. METHODS Twelve experimental runs of atorvastatin-zein nanosphere formula were formulated by a liquid-liquid phase separation method according to custom fractional factorial d...

We report the results from a computational study of the self-assembly of amphiphilic ditethered nanospheres using molecular simulation. We explore the phase behavior as a function of nanosphere diameter, interaction strength, and directionality of the tether–tether interactions. We predict the formation of seven distinct ordered phases. We compare these structures with those observed in linear ...

The $x$-$y$ motion of a nanosphere levitated in tweezer trap cavity has applications as quantum sensor for the direction ultraweak external forces. backaction optical field rotates orientation modes. An experimental demonstration shows accurate measurement, control, and even suppression change relative to lab frame.

Perovskite/silicon tandem solar cells, by combining perovskite as a top absorber material and crystalline silicon bottom material, can expand enhance the utilization of spectrum. Therefore, such structure shows great potential to break through Shockley-Queisser (SQ) limit 31%－33% for single-junction (SJ) cells is considered one most promising approaches achieving higher performance in photoelec...

We theoretically study the low-energy scattering of ultracold atoms by a dielectric nanosphere silica glass levitated in vacuum. The atom and surface interact via dispersion force which strength sensitively depends on polarizability, function, geometry. For cesium rubidium atoms, respectively, we compute atom-surface interaction characterize stationary states taking adsorption onto into account...

We study the resonant fluorescence emission spectrum and intensity-intensity correlations of emitted fluorescent field by a V-type quantum emitter (QE) which is located near metal nanosphere. For description studied phenomena, we use density matrix equations methodology combined with electromagnetic calculations obtain results for profile second-order correlation functions associated photons.
