Aligned carbon nanotube (CNT) structures are promising for many applications; however, as-grown CNT "forests" synthesized by chemical vapor deposition (CVD) are typically low-density and mostly comprise tortuous defective CNTs. Here, we present evidence that the density and alignment of self-organized CNT growth is li…
The use of phenylalanine derived non-toxic carbon dots (C-dots) as a vehicle for the delivery of widely used anti-psychotic drug haloperidol (HaLO) is described in the present research work. The C-dots were found to have remarkable optical properties and to exhibit bright green fluorescence under UV light (λex = 365 n…
Nanoparticles have several biomedical and industrial applications in diagnosis of disease, targeted chemotherapy and in drug delivery. Multifunctionality and sub-micronic size is the main characteristics of nanoparticles. Nanoparticles can be integrated with ligands, imaging labels, therapeutic agents and other functi…
We have developed a Boolean NAND logic gate for the fluorescent detection of nitrite ions by using bovine serum albumin (BSA) functionalized gold nanoclusters.
Copper ferrite (CuFe2O4) magnetic hollow fibers were prepared by applying an organic sol-thermal decomposition method, and silver nanoparticles were subsequently loaded on the fibers by calcination. The Ag–CuFe2O4 fibers exhibited excellent antibacterial efficacy against four different bacteria (E. coli, S. typhi, S.…
The rheological response, in particular the non-linear response, to oscillatory shear is experimentally investigated in colloidal glasses. The glasses are highly concentrated binary hard-sphere mixtures with relatively large size disparities. For a size ratio of 0.2, a strong reduction of the normalized elastic moduli…
Mixed CeO2–TiO2 systems have been synthesized using the sol–gel technique in a symmetric range of nominal compositions (10, 50 and 90 mol% CeO2). The solid materials were characterised using a variety of diffractometric and spectroscopic techniques. The intimate contact between the two components during the synthesis…
Fabrication of modern nanomaterials and nanostructures with specific functional properties is both scientifically promising and commercially profitable. The preparation and use of nanomaterials require adequate methods for the control and characterization of their size, shape, chemical composition, crystalline structu…
GdOF:Ln(3+) (Ln = Eu, Tb, Tm, Dy, Ho and Sm) microspheres (1.5 μm) with high uniformity and monodispersity have been synthesized via a facile hydrothermal method followed by heat treatment (600 °C). X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmissi…
It is demonstrated that interactions between nanoparticles and topological defects induce a twist-grain boundary phase in a chiral liquid crystal. The occurrence of this phase, the analogue of the Shubnikov phase in type-II superconductors, is driven by direct interactions between surface-functionalized CdSe quantum d…
Partial hydrolysis of AlCl3 with Ca(OH)2 and the amino acid glycine enables the selective transformation of the Al13 Keggin structures, outlining the ε → δ → γ isomerization process. Through this, a new γ-Al13 Keggin structure was able to be isolated and characterized through (27)Al NMR and single-crystal XRD.
Nanofibers and nanotubes have recently gained substantial interest for potential applications in tissue engineering due to their large ratio of surface area to volume and unique microstructure. It has been well proved that the mechanical property of matrix could be largely enhanced by the addition of nanoscaled fibers…
The last two decades have witnessed a wealth of research addressing the possible biomedical applications of carbon nanotubes. These new nanomaterials possess unique properties but, at the same time, present several challenges including poor solubility, potential toxicity and biopersistance. The present work reviews re…
Graphene layer-layer interaction is explored as a function of the misorientation angle. A stepwise potential energy surface (PES), where the optimized commensurate configuration (AB stacking) corresponds to the global minimum and all incommensurate configurations correspond to nearly equal energies, is shown. The step…
We have developed a highly sensitive SERS-based sandwich immunoassay by utilizing two derivatives of gold nanostars simultaneously. One is densely packed self-assembled substrates of gold nanostars and the other is labeled immune nanostar aggregates. Taking advantage of the electromagnetic field coupling between tips…
Graphene nanoplatelet–lead styphnate composites (GLS) were prepared either by adding graphene nanoplatelets (GNP) to the reaction solution or by coating normal lead styphnate (LS) with GNP. The composites exhibited excellent anti-electrostatic performance with depressed electrostatic spark sensitivity and static elect…
Noble metal nanoclusters have emerged as a fascinating area of widespread interest in nanomaterials. Herein, we report the synthesis of the PEI-templated gold nanoclusters (PEI-AuNCs) as an efficient carrier for gene delivery. The PEI-AuNCs integrate the advantages of PEI and AuNCs: the presence of AuNCs can effective…
Glutathione protected, silver clusters were synthesized within gel cavities, using sunlight. Compared to the conventional chemical reduction process, this method is cheaper and environmentally friendly as it involves the use of natural resources. The as-synthesized silver quantum clusters in aqueous medium show a dist…
Inspired by the structure and function of coral in nature, a series of composite electrode materials were prepared via depositing conducting polymers, such as polyaniline (PANi), polythiophene (PTh) and polypyrrole (PPY), on the surface of monolithic coral-like porous carbon (MC). MC with a specific surface area as hi…
A series of nickel sulfide nanocrystallines with hierarchical structures was successfully fabricated in situ on a nickel substrate. The nanocrystalline materials with three dimensional (3D) structures were synthesized via self-assembly under moderate conditions, with ethylenediamine and ethylene glycol as the mixed so…
