A fairly general and direct synthesis for the preparation of silica microbelts with a novel stacked structure and controllable wetting behavior by using a combination of sol–gel chemistry and electrospinning techniques was explored successfully. The formation mechanism of the stacked structure and the potential applic…
Neutron-irradiated graphite to a total dose of 3.6 × 1016 n cm−2 was studied by DSC, Raman spectroscopy and transmission electron microscopy (TEM). The Wigner energy of neutron-irradiated graphite was 9.5 J/g as measured by DSC; it was released with an exothermal peak at 220°C. The Raman spectroscopy has confirmed the…
The Ba 0.3 Sr 0.6 Ca 0.1 TiO 3 (BSCT) powder was prepared through the solid-state reaction. And then preparing ceramic samples with quantitative doped- Bi 2 O 3 ⋅3TiO 2 and different doped- MgO . X-ray diffractometer (XRD) and scanning electron microscopy (SEM) were used to investigate the phase compositions, distribu…
We prepare a zinc oxide‐ (ZnO‐) based Schottky diode constructed from the transparent cosputtered indium tin oxide‐ (ITO‐) ZnO ohmic contact electrode and Ni/Au Schottky metal. After optimizing the ohmic contact property and removing the ion‐bombardment damages using dilute HCl etching solution, the dilute hydrogen pe…
We have succeeded in in situ and simultaneously observing the redox reaction of palladium and the oxygen storage/release process in a newly developed palladium-promoted Sr–Fe–O (Pd/Sr–Fe–O) catalyst during redox-gas cycles using dispersive X-ray absorption fine structure (XAFS) analysis at 673 K with a time resolution…
The amorphous nickel hydroxide nanospheres have been prepared by a simple and green electrochemistry technique, and the magnetism measurements of the products show that the prepared amorphous nickel hydroxide nanospheres present ferromagnetism below the Curie temperature of 16.5 K, accompanied by high magnetization of…
Switchable polymer multilayer coatings consisting of poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAA) were prepared via Layer-by-Layer (LbL) assembly and post-functionalized with poly(ethylene glycol methyl ether) (PEG). This resulted in a soft polar coating that reversibly and repeatedly rearranges from hydroph…
Understanding and measuring the size-dependent surface strain of nanowires are essential to their applications in various emerging devices. Here, we report on the diameter-dependent surface strain and Young's modulus of single-crystalline Co nanowires investigated by in situ X-ray diffraction measurements. Diameter-de…
Biradical 2,2':6',2''-terpyridine-6,6''-diyl bis(tert-butyl nitroxide) (tpybNO) showed intramolecular ferromagnetic coupling with 2J/kB = +2.14(10) K and its complex [Zn(tpybNO)(MeOH)2](BF4)2 exhibited intramolecular antiferromagnetic coupling with 2J/kB = -7.5(4) K, suggesting exchange coupling switchable by means of…
This research demonstrates that fluorescent silica nanoparticles containing a lanthanide picolinate complex can be used as optical biolabels by using Candida albicans cells as the model targeting system. As such, new fluorescent biolabels have been prepared by encapsulation of the picolinate terbium(III) complex K2[Tb…
Applications of carbon nanotube (CNT) and graphene in thermal management have recently attracted significant attention. However, the lack of efficient prediction formula for heat transfer coefficient between nanomaterials and gas environment limits the further development of this technique. In this work, a kinetic mod…
Surface oxygen groups play a key role on the performance of porous carbon electrodes for electrochemical capacitors in aqueous media. The electrooxidation method in NaCl electrolyte using a filter press cell and dimensionally stable anodes is proposed as a viable process for the generation of oxygen groups on porous c…
The use of nanotechnology in delivering the chemotherapeutics drug has gained much attention recently. It is capable of killing the cancer much more effectively than any other method. The drug delivery systems using nanocarrier significantly enhances the efficacy of drug by improving the pharmacokinetics and the distr…
This paper proposes a triphasic model of intact skin in vivo based on a general phenomenological thermohydromechanical and physicochemical (THMPC) approach of heterogeneous media. The skin is seen here as a deforming stratified medium composed of four layers and made out of different fluid-saturated materials which co…
We identified a mechanism of fluorescence quenching of CdSe/ZnS quantum dots (QDs) coated with two organic layers, octadecylamine and an amphiphilic polymer containing COOH groups, by nonionic polyoxyethylene-based (C12En) surfactants. The surfactant molecules by themselves do not affect the fluorescence of the QDs. F…
Fine particles of MnBi were prepared by the hydrogen plasma metal reaction method and their magnetic properties were investigated. The particle size of the as-prepared MnBi particles was 70950 nm with a median diameter of 269 nm. Heat treatment and ball milling with a dispersant improved the magnetic properties of the…
The non-luminous precursor, 2-(1-pyrenyl)-9,10-dihydro-9,10-ethanoanthracene-11,12-dione, was photochemically converted to highly-fluorescent 2-(1-pyrenyl)anthracene quantitatively in solution and in the PMMA film and the fluorescence quantum yield of the acene in benzonitrile was as high as 0.99.
Ethyne elaboration of a (porphinato)Zn(II) (PZn) chromophoric core renders fine control over the zero-field splitting (ZFS) parameters of the lowest energy photoexcited triplet state (T1), resulting in the ability to manipulate the spin distribution and establish highly symmetrical coincident optical and magnetic prin…
Given the growing importance of drug and gene delivery systems, imaging agents, biosensors, and theranostics, there is a need to develop new multifunctional and biocompatible platforms. Here we synthesized and fully characterized a family of novel multifunctional and completely monodisperse dendritic platforms. Our sy…
