A BODIPY derivative with an -NH(2) and -OH substituted meso-phenyl group is reported, which, under biological conditions, exhibits metal-induced J-aggregation in the presence of Cu(2+) and a specific fluorescence enhancement for Hg(2+).
We review the state of modeling and simulation of nuclear fuels with emphasis on the most widely used nuclear fuel, UO2. The hierarchical scheme presented represents a science-based approach to modeling nuclear fuels by progressively passing information in several stages from electronic structure calculations to conti…
Tensile specimens of 10B22 (22MnB5) sheet steels were austenitized, quenched to martensite, and tempered at temperatures between 150 and 520°C for various times. The heat treated specimens were charged with 1.7 ppm hydrogen and immediately tested. Fracture surfaces were examined by field emission scanning electron mic…
A new class of compounds containing triarylamine and dicarbazolyl triphenylethylene moieties with high thermal stability and aggregation-induced emission enhancement properties was synthesized. The glass transition temperature and 5% weight loss temperature of 3B-TPA are up to 214.3 °C and 516.8 °C, respectively. The…
Pitting corrosion behavior of stainless steel 304 (SS304) under droplets of chloride solution was investigated using a Kelvin probe (KP). Droplets of different volumes of solution were placed on the steel surface and exposed to a constant low relative humidity (RH). As the concentration increased during the exposure o…
Grafting of [Ln(BH(4))(3)(THF)(3)] (Ln = La, Nd) onto silica affords materials containing well-identified bis(borohydride) surface species. The neodymium-decorated silica converts the beta-butyrolactone monomer into highly isotactic poly(beta-hydroxybutyrate). Under similar conditions, the molecular precursor gives ri…
We report dendrimer complexes which can show triplet-triplet annihilation-supported upconversion from visible light to UV light in aqueous solutions. The Pt complex of octaethylporphyrin as a sensitizer and anthracene as an emitter were accumulated into the water-soluble dendrimers.
Single-crystal tellurium nanowires and nanotubes were selectively synthesized from tellurium powder through a hydrothermal recrystallization route. The nanowires have an average diameter of 40 nm and lengths of several micrometers, while the nanotubes have diameters of 100–200 nm and lengths of 1–2 µm. The morphologie…
Many amphiphile–water mixtures will self-assemble into three-dimensional soft condensed structures known as inverse bicontinuous cubic phases. These structures are found in nature and have applications in nanotechnology. Here we show that by systematically varying amphiphile chain splay, we are able to control the rel…
Generalized dependence of unit cell parameter and oxygen non-stoichiometry on the particle size of nanocrystalline ceria synthesized by a wide variety of solution-based methods was established.
Paclitaxel loaded cerasomes exhibited sophisticated controlled release behavior and remarkably high stability towards surfactant solubilization, long-term storage, acidic treatment, and all factors susceptible to destabilize conventional liposomes, demonstrating that liposomal nanohybrid cerasomes can be a new promisi…
The sputtering of Au targets onto castor oil generates stable spherical gold nanoparticles (AuNPs) of 2.4 to 3.8 nm. The AuNP size increases with the discharge voltage and the mechanism of nucleation and growth are related to the energy of the atoms/clusters ejected from the target.
The antireflection- and antifogging-integrated coatings are widely useful in daily life because they can effectively enhance the transmission of light and meanwhile considerably prevent water condensation. Herein, we present a rapid, straightforward and substrate-independent method for the fabrication of antireflectio…
A methotrexate (MTX)-layered double hydroxide (LDH) hybrid have been developed as a drug delivery system, in which an anticancer drug, MTX, was intercalated into a 2-dimensional LDH nanovehicle to form a nanohybrid. According to the comparative cell viability studies between MTX only and its LDH nanohybrid on MTX sens…
We propose a new self-assembly based strategy for the design of novel lanthanide based luminescent materials. In this approach a europium hydrogel is prepared and sensitization is achieved by doping the gel with pyrene in a non-coordinated fashion.
The importance of relative growth rates in the preponderance of alpha- over gamma-glycine during solution crystallisation has been confirmed. Most surprisingly tailor-made additives drastically accelerated the growth of gamma-glycine--an unexpected and key factor in the polymorphic outcome of glycine crystallisation.
Injury to the skin causes a breach in the protective layer surrounding the body. Many pathogens are resistant to antibiotics, rendering conventional treatment less effective. This led to the use of alternative antimicrobial compounds, such as silver ions, in skin treatment. In this review nanofibers, and the incorpora…
This work investigates the effect of surface topography and biomaterial wettability on protein absorption, cell attachment, proliferation and morphology and reveals important insights in the complexity of cell-material interactions. We use various materials, i.e. poly(dimethyl siloxane) (PDMS), poly(L-lactic acid) (PL…
We report a two-step electrochemical process to grow copper oxide nanowires without the use of templates and surfactants. The first step is to electrochemically corrode amorphous Cu–W oxides pre-sputtered on fluorine-doped tin oxide (FTO) coated glass substrates under positive potentials. The second step is to use the…
Magnetic Ni‐rich Ni–Cu nanoparticles with Ni : Cu mass ratio ( S ) of 2.0 and 2.6 were prepared using a mixture of polyoxyethylene (10) isooctylphenyl ether (Triton X‐100) and sodium dodecyl sulfate (SDS) in a mild hydrothermal condition at 95 º C. X‐ray diffractometry (XRD) showed that the nanoparticles prepared at S…
