Cricket is a popular sport with lengthy duration that makes it challenging to watch in its entirety. Therefore, video summarization techniques are essential providing viewers condensed version of the match's exciting moments. Automated cricket difficult due sport's regulations and extended sessions. Existing methods often include repetitive shots, making summary less concise informative. this p...
The core-shell structured mesoporous silica nanomaterials (MSNs) are experiencing rapid development in many applications such as heterogeneous catalysis, bio-imaging and drug delivery wherein a large pore volume is desirable. We develop a one-pot method for large-scale synthesis of brain-like mesoporous silica nanocomposites based on the reasonable change of the intrinsic nature of the -Si-O-Si...
Semiconducting organic-inorganic nanocomposites comprising the conjugated polymer poly(3-hexylthiophene) (P3HT) in intimate contact with CdSe nanocrystals were crafted by exploiting rationally designed P3HT-grafted cadmium precursors (i.e., Cd-P3HT complexes). The bifunctional ligand 4-bromobenzyl phosphonic acid (BPA-Br) that possesses two terminal functional groups at each end was employed, e...
The discovery and optimization of functional nanocomposites can be potentially accomplished by joint ab-initio machine learning (ML) exploitation, which is currently hindered the absence an ML model to appropriately describe intermonomer interactions in atomic scale. We developed a deep named double-region network (DRN) fill this gap via simultaneously multi-scale interactions. An ultra-low mea...
Density functional theory calculations were performed to investigate the interactions of NH3 molecules with TiO2/MoS2 nanocomposites in order to completely exploit the adsorption properties of these nanocomposites. Given the need to further comprehend the behavior of the NH3 molecules oriented between the TiO2 nanoparticle and MoS2 monolayer, we have geometrically optimized the complex systems ...
Hybrid silicate materials derived from organo-bridged silsesquioxane precursors, RO3-Si-R'-Si-OR3, where R and R' are organic ligands, represent a remarkably diverse class of nanocomposites capable of forming both Si-O-Si and Si-C-Si bonds with molecular scale homogeneity. Recently, in an effort to better control their structure and function, surfactant-directed self-assembly or self-directed a...
Large-scale biomimetic organic/inorganic hybrid nanocoatings with a nacre-like microstructure were prepared via a facile coassembly process. Different from conventional polymer nanocomposites, these nanocoatings contain a high concentration of nanosheets, which can be well aligned along the substrate surface. Moreover, the nanosheets and polymer matrix can be chemically co-cross-linked. As a re...
The mesoporous Au-TiO2 nanocomposites with different Au concentrations were prepared via a co-polymer assisted sol-gel method. The structures have been characterized by powder X-Ray diffraction, N2 adsorption-desorption isotherms, diffuse reflectance UV-Vis spectroscopy, X-ray photoemission spectroscopy, transmission electron microscopy. Most generated Au nanoparticles were embedded in the meso...
Nanocomposites of layered MoS2 and multi-walled carbon nanotubes (CNTs) with core-shell structure were prepared by a simple solvothermal method. The formation of MoS2 nanosheets on the surface of coaxial CNTs has been confirmed by scanning electron microscopy, transmission electron microscopy, absorption spectrum, Raman spectroscopy, and X-ray photoelectron spectroscopy. Enhanced third-order no...
Organic–inorganic hybrid materials do not represent only a creative alternative to design new materials and compounds for academic research, but their improved or unusual features allow the development of innovative industrial applications. Nowadays, most of the hybrid materials that have already entered the market are synthesised and processed by using conventional soft chemistry based routes ...
