respectively in chlorobenzene and acetonitrile, at 30 °C), followed by its regeneration by quercetin released from the HNT lumen. The advantages of this novel nanoantioxidant are discussed.
We report a novel way to modulate the elastic modulus of azobenzene containing liquid crystal networks (LCNs) by exposure to light. The elastic modulus can cycle between different levels by controlling the illumination conditions. Exposing the polymer network to UV light near the trans absorption band of azobenzene gi…
Multi-layer graphene assemblies (MLGs) or fibers with a staggered architecture exhibit high toughness and failure strain that surpass those of the constituent single sheets. However, how the architectural parameters such as the sheet overlap length affect these mechanical properties remains unknown due in part to the…
We have developed a method that for the first time allowed us to synthesize silica particles in 20 minutes using a sol-gel preparation. Therefore, it is critically important to understand the synthesis mechanism and kinetic behavior in order to achieve a higher degree of fine tuning ability during the synthesis. In th…
Graphene nanoplatelets have been used for synthesis of Fe 3 O 4 -graphene nanocomposite negative electrode. A high-resolution transmission electron microscopy measurements of the graphene areas surrounded by Fe 3 O 4 nanoparticles show that the graphene has folded on itself and the edges have some amounts of waviness…
The new perovskite compound La 0.5 Ba 0.5 FeO 3−δ was prepared by the sol–gel method.
Nickel Oxide (NiO) is an important transition metal oxide with cubic lattice structure. Among the magnetic nanoparticles, fabrication of nickel nanoparticles is often more difficult than that of the other particles. This is because they are easily oxidized. To achieve pure nickel nanocrystals, numerous methods have be…
The enhanced interaction of graphene oxide (GO) and Cu( ii ) with titanium dioxide (TiO 2 ).
A facile and efficient method was developed to synthesize boronic acid polymer brushes immobilized on magnetic graphene oxide for the selective enrichment of glycoproteins from complex biological samples via surface initiated atom transfer radical polymerization (SI-ATRP).
A new Mn 4+ doped hexafluorozirconate complex, Cs 2 ZrF 6 :Mn 4+ , was prepared successfully through a cation exchange route. With introduction of this phosphor, the R a and T c values of a YAG type WLED can be significantly improved, indicating its potential application for warm white lighting.
A robust superhydrophobic coating based on Ni/WS 2 was fabricated successfully through a simple one-step electrodeposition process. This metal-caramic composite coating showed excellent self-cleaning and corrosion resistance properties.
Fast-response and easy-to-visualize colorimetric nanofibrous sensors show great potential for visual and continuous control of external stimuli. This makes them applicable in many fields, including wound management, where nanofibers serve as an optimal support material. In this paper, fast responding and user-friendly…
High-quality graphene oxide (GO) with high crystallinity and electrical conductivity as well as in situ doped with nitrogen and sulfur is obtained via the electrochemical exfoliation of graphite. Furthermore, iron incorporated GO sheets show promising catalytic activity and stable methanol tolerance durability when us…
Density functional theory based methods were used for the analysis of the interaction between BC 3 (a graphene nanosheet doped with boron), pristine and with point defects (vacancies of carbon – V C and boron – V B ), and the H 2 O molecule.
Synergism of gold and silver improves fluorescence behavior of gold–silver bimetallic clusters with practical applications.
Application-oriented patterned growth of transition metal dichalcogenides (TMDCs) and their heterojunctions is of critical importance for sophisticated, customized two-dimensional (2D) electronic and optoelectronic devices; however, it is still difficult to fabricate these patterns in a simple, clean, and high control…
Self-assembly and associated dynamic and reversible non-covalent interactions are the basis of protein biochemistry (e.g., protein folding) and development of sophisticated nanomaterial systems that can respond to and amplify biological signals. In this study, we report a systematic investigation of non-covalent inter…
The structures and electronic properties of the phosphorene and graphene heterostructure are investigated by density functional calculations using the hybrid Heyd-Scuseria-Ernzerhof (HSE) functional. The results show that the intrinsic properties of phosphorene and graphene are preserved due to the weak van der Waals…
A promising route to cancer treatment is hyperthermia, facilitated by superparamagnetic iron oxide nanoparticles (SPIONs). After exposure to an alternating external magnetic field, SPIONs generate heat, quantified by their specific absorption rate (SAR, in W g(-1) Fe). However, without surface functionalization, comme…
Nanoparticle-based cancer diagnosis-therapy integrative systems (cancer theranostics) represent an emerging approach in oncology. To address this issue in the present work iron oxide (γ-Fe2O3-maghemite) nanoparticles (IONPs) were encapsulated within the matrix of (bis(p-sulfonatophenyl)phenylphosphine)-methoxypolyethy…
