The preparation of hollow inorganic capsules defined shape, composition and with tailored properties is immense scientific technological interest. This article mainly features recent research progress towards various methods for preparing porous capsules. By choosing some typical as examples, we present a comprehensive overview synthetic strategies capsules, organic are also included. available broadly categorized into three themes, i.e., hard-templating, soft-templating, template-free...
The formation of tubular nanostructures normally requires layered, anisotropic, or pseudo-layered crystal structures, while inorganic compounds typically do not possess such nanotubes thus have been a hot topic in the past decade. In this article, we review recent research activities on fabrication and focus three novel synthetic strategies for generating from materials that layered structure. Specifically, thermal oxidation method based gas-solid reaction to porous CuO has successfully...

Chalcogen-hyperdoped silicon shows potential applications in silicon-based infrared photodetectors and intermediate band solar cells. Due to the low solid solubility limits of chalcogen elements silicon, these materials were previously realized by femtosecond or nanosecond laser annealing implanted bare certain background gases. The high energy density deposited on surface leads a liquid phase fast recrystallization velocity allows trapping into matrix. However, this method encounters...

Low-cost large-area chirality meta-devices (CMDs) with adjustable optical are of great interest for polarization-sensitive imaging, stereoscopic display, enantioselectivity analysis, and catalysis. Currently, CMDs adjusted chiroptical responses in the mid-infrared to terahertz band have been demonstrated by exploiting photocarriers silicon, pressure, phase-change GSTs but still absent visible band, which turn limits development chiral nanophotonic devices.
