The photoalignment of liquid crystalline materials has been studied extensively over the past two and a half decades and has recently become of technological importance in the liquid crystal display panel industry. This review introduces recent attempts at the photoalignment of liquid crystalline polymers and focuses…
The molybdenum disulfide (MoS2)@ZnO nano-heterojunctions were successfully fabricated through a facile three-step synthetic process: prefabrication of the ZnO nanoparticles, the synthesis of MoS2 nanoflowers, and the fabrication of MoS2@ZnO heterojunctions, in which ZnO nanoparticles were uniformly self-assembled on t…
Density functional theory computations were performed to investigate the adsorption of four organic molecules, including tetracyanoquinodimethane (TCNQ), tetracyanoethylene (TCNE), tetrathiafulvalene (TTF) and benzyl viologen (BV) on the basal plane of MoS2 monolayer (MoS2ML). There mainly exist non-covalent weak inte…
Three-dimensional hierarchically porous carbon-CNT-graphene ternary all-carbon foams (3D-HPCFs) with 3D macro- and mesoporous structures, a high specific surface area (1286 m(2) g(-1)), large bimodal mesopores (5.1 and 2.7 nm), and excellent conductivity have been fabricated through multicomponent surface self-assembl…
The quest for the single-molecular magnets (SMMs) based on mononuclear transition-metal complexes is focused on the low-coordinate species. No transition-metal complex with a coordination number of eight has been shown to exhibit SMM properties. Here the magnetic studies have been carried out for a mononuclear, eight-…
Recently, platinum (Pt) nanoparticles (NPs) have received increasing attention in the field of catalysis and medicine due to their excellent catalytic activity. To rationally design Pt NPs for these applications, it is crucial to understand the mechanisms underlying their catalytic and biological activities. This arti…
Controllable dielectric–magnetic coaxial hybrid nanowires, having a core of SiC nanowires and a shell of Fe3O4 nanoparticles, have been synthesized using a straightforward polyol approach. The morphology, microstructure and magnetic properties of the SiC–Fe3O4 hybrid nanowires have been characterized by transmission e…
Asymmetric supercapacitors featuring both high energy and power densities as well as a long lifespan are much sought after and may become a reality depending on the availability of cheap yet highly active electrode materials. Here, a novel flexible architecture electrode made of NiCoAl‐layered double hydroxide (NiCoAl…
cytotoxic effect of biologically synthesized silver and gold nanoparticles against MDA-MB-231, human breast cancer cells. Formation of silver and gold nanoparticles was observed within 30 min and the various characterization techniques such as UV-vis spectrophotometer, FE-SEM, TEM and XRD studies were confirmed the sy…
Two-dimensional (2D) materials such as graphene, hexagonal boron nitrides (hBN), and transition metal dichalcogenides (TMDs, e.g., MoS2) have attracted considerable attention in the past few years because of their novel properties and versatile potential applications. These 2D layers can be integrated into a monolayer…
Graphene-wrapped ZnO hollow spheres were synthesized by a two-step process, which combined a hydrothermal reaction with surface modification. The experimental results show that reduced graphene oxide sheets adhere entirely to the surface of the ZnO hollow spheres consisting of nanoparticles. The unique structure effec…
Elastic properties of materials are an important factor in their integration in applications. Chemical vapor deposited (CVD) monolayer semiconductors are proposed as key components in industrial-scale flexible devices and building blocks of two-dimensional (2D) van der Waals heterostructures. However, their mechanical…
Current discoveries of different forms of carbon nanostructures have motivated research on their applications in various fields. They hold promise for applications in medicine, gene, and drug delivery areas. Many different production methods for carbon nanotubes (CNTs) have been introduced; functionalization, filling,…
We have experimentally determined the energies of the ground and first four excited excitonic states of the fundamental optical transition in monolayer WS_{2}, a model system for the growing class of atomically thin two-dimensional semiconductor crystals. From the spectra, we establish a large exciton binding energy o…

Nanodielectrics, or dielectric polymer nanocomposites, can exhibit significant improvements in voltage endurance and dielectric breakdown strength compared to unfilled polymer. This work takes advantage of the large interfacial area between the matrix and the filler as a means to introduce chemistry that can further t…
Ultra high molecular weight polyethylene (UHMWPE) is a material used in artificial implants for articular joint replacements. However, these implants have a limited lifespan in which the patient will be pain-free due to the wear of the UHMWPE components. Recently crosslinking, or exposing the material to radiation, ha…
Poly(lactic acid) (PLA) was physically modified by filling with an inorganic additive, natural fibres as well as with a tributyl citrate (TBC). PLA composites were prepared with a film stacking method and analysed by scanning electron microscopy (SEM), thermogravimetry (TGA), thermomechanometry and differential scanni…
This work aims the synthesis and study of ZSM-5 catalysts for the conversion of ethanol to light olefins, especially, using an alternative and inexpensive route. The ethanol emerges as a renewable source for the production of olefins and the ZSM-5 catalyst has important characteristics for this type of reaction such a…
