One-dimensional SrSn(OH) 6 nanowires were successfully synthesized through a rapid simple method—sonochemical synthesis at room temperature without using any templates or surfactants. The growth mechanism has been proposed, and the reaction conditions were carefully investigated. The experimental results revealed that…
New fluorescent probes, designed based on the molecular rotor motif, displayed good affinity for aggregated β-amyloid peptides. The physical and fluorescence properties of these probes can be fine tuned by modifying their chemical structures. These findings suggest that the general motif of molecular rotors can lead t…
We report a study of the effect of the growth base pressure on the thermoelectric (TE) properties of indium antimonide (InSb) nanowires (NWs) synthesized using a vapour–liquid–solid method at different base pressures varying from ambient to high vacuum. A suspended device was used to characterize the TE properties of…
In this study, we report on the fabrication of the nanoassemblies consisting of the poly( N -isopropyl acrylamide) (PNIPAAm) brushes immobilized with gold nanoparticles (Au NPs). The employed process involves grafting of the carboxyl terminated PNIPAAm chains on an underlying substrate in a brush conformation followed…
A detailed nuclear magnetic resonance and Raman study of ${\text{Ge}}_{x}{\text{Se}}_{1\ensuremath{-}x}$ glasses indicate that the glass structure is composed of intertwined microdomains of ${\text{GeSe}}_{2}$ and ${\text{Se}}_{\text{n}}$. Static nuclear magnetic resonance spectra of glasses ranging from $0\ensuremath…
The effects of boron and nitrogen doping on the transport properties of zigzag-edged graphene nanoribbons (ZGNRs) with antiferromagnetically coupled edge states are investigated by first-principles electronic structure combined with a nonequilibrium Green's function technique. Specifically, the effects produced by sin…
We describe molecular capturing properties of protein nanotubes with a controllable ligand binding affinity and size selectivity. These practical biocylinders were prepared using an alternating layer-by-layer (LbL) assembly of protein and oppositely charged poly(amino acid) into the nanoporous polycarbonate (PC) membr…
The optical signal of a localized surface plasmon resonance (LSPR)-based sensor combined with electrochemistry was investigated. Gold nanoparticles were immobilized on an indium tin oxide (ITO) substrate, which functioned as working electrode. Using cyclic voltammetry synchronized with LSPR sensing, surface reactions…
Liquid paraffin-water emulsions were prepared by homogenizing oil phases containing sorbitan oleate (Span 80) and aqueous phases containing layered double hydroxide (LDH) particles or Laponite particles. While water-in-oil (w/o) emulsions are obtained by combining LDH with Span 80, the emulsions stabilized by Laponite…
Abstract We examined the effects of chitosan oligosaccharides (COSs) with different molecular weights (COS-A, 10 kDa < MW < 20 kDa; COS-C, 1 kDa < MW < 3 kDa) on the lipopolysaccharide (LPS)-induced production of prostaglandin E2 and nitric oxide and on the expression of cyclooxygenase-2 and inducible nitr…
The universal structural role of collagen fiber networks has motivated the development of collagen gels, films, coatings, injectables, and other formulations. However, reported synthetic collagen fiber fabrication schemes have either culminated in short, discontinuous fiber segments at unsuitably low production rates,…
The formation of resistance-free or Ohmic contacts at metal/organic interfaces remains a significant challenge for achieving high-performance organic electronic devices such as organic light-emitting diodes. Several oxides have recently been reported to yield extremely low-voltage devices and thus have excited a renew…
N-Centred benzene-1,3,5-tricarboxamides (N-BTAs) composed of chiral and achiral alkyl substituents were synthesised and their solid-state behaviour and self-assembly in dilute alkane solutions were investigated. A combination of differential scanning calorimetry (DSC), polarisation optical microscopy (POM) and X-ray d…
One of the unusual features of the ${M}_{n+1}A{X}_{n}$ phases (where $M$ is a transition metal, $A$ is a group A element, $X$ is carbon or nitrogen, and $n=1,2,3\dots{}$) is that for a given $M\text{\ensuremath{-}}A\text{\ensuremath{-}}X$ system, only certain values of $n$ are found to occur and there is no systematic…
Precise imaging of cellular and subcellular structures and dynamic processes in live cells is crucial for fundamental research in life sciences and in medical applications. Non-fluorescent nanoparticles are an important type of optical probe used in live-cell imaging due to their photostability, large optical cross-se…
Mn 5 O 8 nanorods were prepared by a topotactic conversion of γ-MnOOH nanorod precursors in nitrogen at 400 °C. The as-prepared Mn 5 O 8 nanorods crystallized in a monoclinic structure (space group C 2/ m ) with unit cell dimensions a = 10.3784(2) Å, b = 5.7337(7) Å, c = 4.8668(6) Å, and β = 109.491(6)°, having a comp…
The electrochemical dealloying of rapidly solidified Al-based alloys in a 1 M NaCl aqueous solution has been investigated using electrochemical measurements in combination with microstructural analysis. The results show that nanoporous metals (Au, Ag, Pd and Cu) with various morphologies can be fabricated through elec…
Our first-principles calculations show that both the compressional and shear waves of hcp-Fe become elastically isotropic under the high temperatures of Earth inner core conditions, with the variation in sound velocities along different angles from the c axis within 1%. We computed the thermoelasticity at high pressur…
We demonstrate that the transient non-autonomous dynamics of a spin torque nano-oscillator (STNO) under a radio-frequency (rf) driving signal is qualitatively different from the dynamics described by the Adler model. If the external rf current $I_{rf}$ is larger than a certain critical value $I_{cr}$ (determined by th…
Pulsed laser deposition (PLD) of homoepitaxial SrTiO(3) 001 was studied with in situ x-ray specular reflectivity and surface diffuse x-ray scattering. Unlike prior reflectivity-based studies, these measurements access both time and length scales of the evolution of the surface morphology during growth. In particular,…
