We studied in detail the electronic properties of C44H10F20N4 (tetrakis(pentafluorophenyl)porphyrin, hereafter H2TPP(F)) via a combined study by photoelectron spectroscopy (PES) and density functional (DF) calculations, shedding new light on the role of the halide in this very interesting molecule for organic electron…
Three novel polyoxometalates (POMs) containing [Ni6(μ3-OH)3](9-) and [P2W15O56](12-) units were first made, showing the first hexa-nuclearity transition-metal substituted POMs (TMSPs) based on monomeric lacunary Dawson fragments, which further indicates that the hydrothermal technique can offer an effective way for ma…
Silver nanoparticles, AgNPs, are widely used in our daily life, mostly due to their antibacterial, antiviral, and antifungal properties. However, their potential toxicity remains unclear. In order to unravel this issue, emissive AgNPs were first synthetized using an inexpensive photochemical method, and then their per…
We propose a new acrylate monomer that exhibits attractive optical properties, such as good transparency, high refractive index, low birefringence, desirable optical properties, and high thermal stability. Tetraphenylethane has four aromatic rings that bind without anisotropy. A polymer with this tetraarylethane struc…
Reactions of H2salen (H2L, N,N'-ethylene bis(salicylideneimine)) with Yb(CF3SO3)3, Yb(OAc)34H2O and Yb(NO3)36H2O in MeOH–EtOH under reflux gave NIR luminescent complexes [Yb6L9(H2L)2] (1), [Yb3L3(HL)(OH)2] (2) and [Yb2L2(H2L)2(NO3)(MeOH)2]NO3 (3), respectively.
Compared to C60, carbon nanotubes, and graphite, graphene more effectively lowers the dehydrogenation temperature and improves the dehydrogenation kinetics of LiAlH4. With 15 wt% graphene incorporation, the initial hydrogen release temperature is ~80 °C (60 °C lower than that of pristine LiAlH4).

Rationally engineering photocatalytic devices that power water splitting or CO2 reduction reactions requires identifying economical materials that efficiently absorb sunlight and have suitable band edge placements. Recent theoretical investigations have predicted that a 1 : 1 alloy of MnO and ZnO meets these criteria.…
Citrate-reduced silver nanoparticles (Ag-NPs) are used extensively for surface-enhanced Raman scattering (SERS) studies, but are typically found to aggregate using an aggregation agent. This study is aimed at developing a simple, stable, and reproducible aggregated method for Ag-NPs without any aggregation agents in a…
Graphene has got considerable attention in both experimental and theoretical fields for its extraordinary properties. Covalent functionalization is an efficient strategy to render graphene additional properties and overcome its shortcomings such as zero band gap and nondispersibility in solvents. This study reports th…

Ferroelastic β′-Gd2(MoO4)3 and β′-Eu2(MoO4)3 crystals were synthesized through the crystallization of 21.25Gd2O3–63.75MoO3–15B2O3 glass and 22.5Eu2O3–47.5MoO3–30B2O3 glass, respectivelty, and their magnetism and photoluminescence properties were examined. It was demonstrated from the temperature dependence of the magn…
Pepsin-solubilized collagen (PSC) was extracted from the body wall of crown-of-thorns starfish (COTS) (Acanthaster planci) using pepsin digestion in 0.5 M acetic acid. The electrophoretic pattern of PSC showed that it consisted of two α chains (α1 and α2 chains). In addition, the peptide mapping showed that there were…
UNLABELLED: 195mPt-cisplatin is regarded as a promising imaging agent for optimizing dosage in patients receiving cisplatin chemotherapy. METHODS: We investigated the whole-body distribution and radiation dosimetry of 195mPt-cisplatin in humans. Whole-body scans were obtained up to 144 h after intravenous injection of…
We have investigated the low-temperature physical properties of BaTi2Sb2O and Ba1−xNaxTi2Sb2O (x=0.05, 0.1, 0.15, 0.2, 0.25, 0.3) by means of muon spin rotation (μSR) and SQUID magnetometry. Our measurements reveal the absence of magnetic ordering below TDW=58 K in the parent compound. Therefore the phase transition a…
The corrosion rates in the presence of some indole derivates, namely, 9H-pyrido[3,4-b]indole (norharmane) and 1-methyl-9H-pyrido[3,4-b]indole (harmane), as inhibitors of C38 steel corrosion inhibitor in 1 M HCl solution, were measured by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) tec…
In the combustion zone of industrial- and aero- gas turbines, thermomechanical fatigue (TMF) is the dominant damage mechanism. Thermomechanical fatigue is a coupling of independent creep, fatigue, and oxidation damage mechanisms that interact and accelerate microstructural degradation. A mixture of intergranular crack…
This paper presents the realisation of conductive matrices for application to tissue engineering research. We used poly(L-lactide (PLLA)), poly(epsilon-caprolactone) (PCL), and poly(lactide-co-glycolide) (PLGA) as polymer matrix, because they are biocompatible and biodegradable. The conductive property was integrated…
By using 1,5-pentanediol as a capping and structure directing agent, ultrathin Eu2O3 nanosheets (<1 nm) have been synthesized and assembled into a layered structure. The lateral dimensions of the nanosheets can be tuned by simply controlling the reaction time. These layered structures exhibit a strong quantum size eff…
In the field of tissue engineering, polymeric materials with high biocompatibility like polylactic acid and polyglycolic acid have been widely used for fabricating living constructs. For hypopharynx tissue engineering, skeletal muscle is one important functional part of the whole organ, which assembles the unidirectio…
