A thermal transition is observed in the peptide amphiphile C16-KTTKS (TFA salt) from nanotapes at 20 °C to micelles at higher temperature (the transition temperature depending on concentration). The formation of extended nanotapes by the acetate salt of this peptide amphiphile, which incorporates a pentapeptide from t…
Physical properties at the nanoscale are novel and different from those in bulk materials. Over the last few decades, there has been an ever growing interest in the fabrication of nanowire structures for a wide variety of applications including energy generation purposes. Nevertheless, the study of their transport pro…
To compensate for the low sensitivity of magnetic resonance imaging (MRI), nanoparticles have been developed to deliver high payloads of contrast agents to sites of disease. Here, we report the development of supramolecular MRI contrast agents using the plant viral nanoparticle tobacco mosaic virus (TMV). Rod-shaped T…
This study is a thorough evaluation of clay-based Layer-by-Layer (LbL) coatings intended to reduce the flammability of polymeric materials. Through a systematic variation of a baseline coating recipe, an ideal combination of the coating attributes that provides a rapidly developing coating with an optimum balance of f…
A novel strategy is provided in this paper to design multi-stimuli-responsive luminescent materials by taking a multi-responsive chromophore which responds to multiple environmental stimuli instead of constructing multi-chromophore systems. Herein, we have successfully prepared a tri-stimuli-responsive luminescent mat…
A novel approach for the synthesis of colloidal silver nanoprisms (AgNPrs) with controllable localized surface plasmon resonance (LSPR) via a chemical shape transformation of silver nanospheres (AgNSs) is presented. The shape conversion is carried out by feeding hydrogen peroxide (H2O2) solution into a starch-stabiliz…
Covalent organic polymer-4 (COP-4) supported palladium (Pd) catalysts were prepared for the first time. The Pd particles are highly dispersed into pores of COP-4 with electron reduction and the use of N,N-dimethylformamide (DMF) as the solvent. The catalysts show high activity for CO oxidation.
In this paper, polyaniline nanofibers were deposited on the surface of fabrics and generated a rough structure similar to the micromorphology of a lotus leaf via the oxidative chemical polymerization of aniline. After modification with n-octadecyl thiol, water-repellent fabrics were obtained. Interestingly, the as-pre…
Low mechanical stability of superhydrophobic surfaces is the bottle neck we are facing for their practical applications. Here we report facile fabrication of durable superhydrophobic textiles by dip coating in a nanocomposite solution of fluoro-free organosilanes. The kind of organosilane, molar ratio of organosilane…
With the extensive progress in nanotechnology-based drug delivery systems, pharmacokinetic evaluations have gained much attention from researchers as a central part of the study of these systems. Because the fulfillment of any therapeutic goal(s) by a novel drug delivery system requires that the absorption, distributi…
Stable monodispersed amorphous calcium carbonate (ACC) nanoparticles can be synthesized in ethanol media by a facile method, and crystallization of ACC is kinetically controlled, resulting in the formation of three polymorphs in a mixed solvent of ethanol-water at different pH values.
This research focused on using a block copolymer of poly(ethylene glycol) and poly(propylene glycol) as a new type of compatibilizer in poly(lactic acid)/polycaprolactone (PLA/PCL) blends. The blends were prepared at 80/20 by a melt blending method, and concentrations of the block copolymer were varied from 0-10 phr.…
Based on the consideration that compound 1 with a -PO3H2 group can be hydrolyzed into compound 3 which shows low solubility in aqueous solutions and thus aggregation can occur easily, a new fluorescence turn-on assay has been constructed for alkaline phosphatase (ALP) with compound 1. ALP at concentrations as low as 1…
The rapid emergence of gold nanoparticles (AuNPs) technology holds great promise for future applications due to their large volume specific surface areas with high diverse surface activities than bulk gold. These properties have made AuNPs of great importance in the development of excellent nanoelectronic chips, promi…
In addressing the global demand for clean and renewable energy, hydrogen stands out as the most suitable candidate for many fuel applications that require practical and efficient storage of hydrogen. Supplementary to the traditional hydrogen storage methods and materials, the high-pressure technique has emerged as a n…
Prompted by recent experimental achievement of transition metal (TM) atoms substituted in MoS2 nanostructures during growth or saturating existing vacancies (Sun et al., ACS Nano, 2013, 7, 3506; Deepak et al., J. Am. Chem. Soc., 2007, 129, 12549), we explored, via density functional theory, the magnetic properties of…
The replacement of coordinated acetylacetonate for nitrate around a Dy(III) ion results in the enhancement of the single molecule magnet properties of a {Co(III)2Dy(III)2} complex, resulting in a large thermal energy barrier and reduced quantum tunnelling at low temperatures. The analogous Tb(III) complex displays fie…
Here, we report the fabrication of ultrafine nanoporous PdFe/Fe3O4 electrocatalysts by a facile dealloying strategy. The results show that the phase formation of the as-dealloyed samples is dependent upon the Pd : Fe atomic ratio in the Al–Pd–Fe ternary precursors. The size of ligaments is as small as ∼2 nm in the nan…
Boron nitride nanotube (BNNT)@mesoporous silica hybrids with controllable surface zeta potential were fabricated for intracellular delivery of doxorubicin. The materials showed higher suspension ability, doxorubicin intracellular endocytosis efficiency, and LNcap prostate cancer cell killing ability compared with nake…
The electric field control of magnetism in the solid state has become a very active topic of research recently, made possible by the advances in the synthesis and fabrication of new materials and artificial heterostructures. Key strategies include structural manipulation through epitaxial growth to create single cryst…
