The thermal conductivity $\ensuremath{\kappa}$ of the iron-arsenide superconductor ${\mathrm{Ba}}_{1\ensuremath{-}x}{\mathrm{K}}_{x}{\mathrm{Fe}}_{2}{\mathrm{As}}_{2}$ was measured for heat currents parallel and perpendicular to the tetragonal $c$ axis at temperatures down to 50 mK and in magnetic fields up to 15 T. M…
Topographic images of [Fe(Htrz)₂(trz)](BF₄) nanoparticles were acquired across the first-order spin transition using variable-temperature atomic force microscopy (AFM) in amplitude modulation mode. These studies revealed a complex morphology of the particles consisting of aggregates of small nanocrystals, which expand…
Hydrogen can be converted to thermal energy by combustion or to electricity energy by fuel cells. Considering the stringent requirements for safety from fire hazards and elimination of pollutants, the flameless catalytic combustion of hydrogen is favorable over conventional flame combustion for residential heat supply…
Cycloaliphatic epoxy resin (3–4-epoxycyclohexane) methyl 3–4-epoxycyclohexyl-carboxylate (ECC) was formulated with flexible hydrogenated bisphenol A diglycidyl ether (HBADGE) to inspect the influence of chain flexibility on the performance and reliability of epoxy packaged Light-emitting Diode (LED). The properties of…
The buffer in geological disposal system is one of the major elements to restrain the release of radionuclide and to protect the container from the inflow of groundwater. The buffer material requires long-term stability, low hydraulic conductivity, low organic content, high retardation of radionuclide, high swelling p…
Diamond-like carbon (DLC) coatings show strident properties such as high wear resistance and ultra-low friction. However, a widespread use regarding energy efficiency issues is neglected due to the poor adhesion. Silicon adhesion interlayers (SiC x :H) were deposited at different temperatures from 50 to 500°C with hex…
To date, the breadth of scientific research that has been devoted to investigating the photochemical and photophysical behavior of the lanthanide elements has generally fallen into one of two camps: solution studies of luminescent lanthanide metal–ligand complexes or investigations of solid-state nanoparticles, compos…
The Japanese Patent Applications filed on the topic of nickel/metal hydride (Ni/MH) batteries have been reviewed. Patent applications filed by the top nine battery manufacturers (Matsushita, Sanyo, Hitachi Maxell, Yuasa, Toshiba, FDK, Furukawa, Japan Storage, and Shin-kobe), five component suppliers (Tanaka, Mitsui, S…
Based on our previous work on the PLGA nanoparticles modified with biotinylated chitosan (Bio-CS-PLGA NPs), we further studied the stability, toxicity, pharmacokinetics, and in vivo efficacy. The safety of NPs was studied through single-dose toxicity test in mice, and the result showed that NPs were well tolerated at…
The term ‘history effect’ refers to the contribution of any past mass transfer events between a gas bubble and its liquid surroundings towards the current diffusion-driven growth or dissolution dynamics of that same bubble. The history effect arises from the (non-instantaneous) development of the dissolved gas concent…
OBJECTIVES: Lung cancer remains a deadly disease with unsatisfactory overall survival. Cisplatin, a standard platinum (Pt)-based chemotherapeutic agent, has the potential to inhibit the growth of lung cancer. Its use, however, is occasionally limited by severe organ toxicity. However, until now, no systematic study ha…
Targeted polymer capsules can selectively bind to unstable plaques in mice after intravenous injection. Different formulations of the capsules are explored with a synthetic/biopolymer hybrid capsule showing the best stability and small-molecule drug retention. The synthetic polymer is composed of pH-sensitive blocks (…
The corrosion behavior of Ti60 alloy covered with a solid NaCl deposit in wet oxygen flow at 600 °C has been studied further by SEM, EDX, XPS, XRD, TEM and EPMA analysis. The results show that solid NaCl and H2O react with Ti oxides, which destroyed the Ti oxide scale to yield the non-protective Na4Ti5O12 and other vo…
A mixture of ferrocene-based tetratopic pyridyl ligands FcL1 and FcL2 undergoes self-sorting upon competitive coordination with AgBF4, affording homomeric nanotubes FcNT1 and FcNT2 as a mixture. No mutual interference for the nanotubular growth occurred between FcNT1 and FcNT2 even when one of these ligands was used i…
By combining experimental measurements and computer simulations, we here show that for the bola-like peptide amphiphiles XI4 X, where X=K, R, and H, the hydrophilic amino acid substitutions have little effect on the β-sheet hydrogen-bonding between peptide backbones. Whereas all of the peptides self-assemble into one…
Five hundred-nanometer-thick ZnO-based textured polycrystalline films consisting of 490-nm-thick Al-doped ZnO (AZO) films deposited on 10-nm-thick Ga-doped ZnO (GZO) films exhibited a high Hall mobility (μ H) of 50.1 cm(2)/Vs with a carrier concentration (N) of 2.55 × 10(20) cm(-3). Firstly, the GZO films were prepare…
In the present study, magnetic nanoparticles (NP, nickel ferrite) in different concentrations into ferroelectric liquid crystal (FLC) mixture have been prepared and studied. The effect of nickel ferrite concentration on the electro-optic, dielectric and optical properties of FLC mixture has been studied and discussed.…
Micro and nanotechnologies are called to play a key role in the fabrication of small and low cost sensors with excellent performance enabling new continuous monitoring scenarios and distributed intelligence paradigms ( Internet of Things , Trillion Sensors ). Harvesting devices providing energy autonomy to those large…
A novel flame‐retardant unsaturated polyester (UP) was obtained by introducing ammonium polyphosphate (APP) and aluminum hypophosphite (AHP) into UP matrix. The UP/APP/AHP composites obtained were characterized by Fourier Transform Infrared Spectra (FTIR). From limiting oxygen index (LOI), microscale combustion calori…
We report synthesis and time-resolved transient absorption measurements of TiS3 nanoribbons. TiS3 nanoribbons were fabricated by direct reaction of titanium and sulfur. Dynamics of the photocarriers in these samples were studied by transient absorption measurements. It was found that following ultrafast injection of n…
