Multiscale Models of CVD Process: Review and Prospective.

Chemical vapor deposition (CVD) is a crucial technique in the preparation of high-quality thin films and coatings, and is widely used in various industries including semiconductor, optics, and nuclear fuel, due to its operation simplicity and high growth rate. The complexity of the CVD process arises from numerous parameters, such as precursor chemistry, temperature, pressure, gas flow dynamics, and substrate characteristics. These multiscale parameters make the optimization of the CVD process a challenging task.

Study on Spontaneous Combustion "Three Zones" of the Distribution Law and Integrated Fire Prevention Technology in Mined-Out Area of Lingquan Mine.

To determine the risk range of remaining coal in the goaf of the higher slice on the seventh mining and fifth face of Lingquan Mine, the beam tube monitoring system was adopted to supervise the temperature and gas content changes in the goaf during the normal mining period of the working face. As per the principle of dividing spontaneous combustion "three zones" (SCTZ), numerical simulation of the distribution of SCTZ in the goaf of the work face was performed. The O content and index gas in the goaf were measured and analyzed, and combined with the in-situ measurement outcomes, the distribution of SCTZ in the goaf was determined through the FLUENT numerical modeling program.

Mass Production of 3D Connective Graphene Networks by Fluidized Bed Chemical Vapor Deposition and Its Application in High Performance Lithium-Sulfur Battery.

Three-dimensional (3D) graphene with novel nano-architectures exhibits many excellent properties and is promising for energy storage and conversion applications. Herein, a new strategy based on the fluidized bed chemical vapor deposition (FB-CVD) process was proposed to prepare 3D graphene networks (3DGNs) with various nano-architectures. Specially designed SiC-C@graphene core/shell nanoparticles were prepared taking the advantages of the FB-CVD system, and 3DGNs with hierarchical nanostructures were obtained after removing the SiC core.

Bioinspired nanoplatelets for chemo-photothermal therapy of breast cancer metastasis inhibition.

Breast cancer is associated with high mortality due to tumor metastasis. The anti-metastasis efficacy of photochemotherapy is strictly limited by poor targeting capability with respect to circulating tumor cells (CTCs) in blood and lymph. Herein, we decorate the platelet membrane (PM) on a surface of nanoparticles (NPs), referred to as nanoplatelets.

The On-Off chiral mesoporous silica nanoparticles for delivering achiral drug in chiral environment.

In the current stage, the On-Off mechanism of chiral mesoporous silica nanoparticles (CMSN) for delivering achiral drug in chiral environment has rarely been reported. Herein, On-Off chiral mesoporous silica nanoparticles (On-Off-D-CMSN and On-Off-L-CMSN) were successfully synthesized and its particular contribution in delivering achiral drug indometacin (IMC) in chiral environment was mainly studied. The as-synthesized On-Off-D-CMSN and On-Off-L-CMSN were verified by fourier transform infrared spectrometer and circular dichroism.
