We have investigated the high-temperature thermoelectric properties of the layered compound LaO1−xFxBiS2. The electrical resistivity of LaOBiS2 showed an anomalous behavior; a metal-semiconductor transition was observed around 270 K. It was found that the value of the electrical resistivity decreased with F substituti…
A key to improve the electrochemical performance of energy storage systems (e.g., lithium ion batteries and supercapacitors) is to develop advanced electrode materials. In the last few years, although originating from the unique structure and property of graphene, interest has expanded beyond the originally literally…
Bexarotene (Targretin) is a retinoid X receptor (RXR) agonist that has applications for treatment of T cell lymphoma and proposed mechanisms of action in Alzheimer's disease that have been the subject of recent controversy. Carbon-11 labeled bexarotene ([(11)C-carbonyl]4-[1-(3,5,5,8,8-pentamethyltetralin-2-yl)ethenyl]…
Nuclear magnetic resonance (NMR) and X-ray diffraction (XRD) experiments reveal the structural importance of divalent cation-phosphate complexes in the formation of β-sheet nanocrystals from phosphorylated serine-rich regions within aquatic silk from caddisfly larvae of the species Hesperophyla consimilis. Wide angle…
The investigation on interactions between tetraphenylporphyrin (TPP) and α-Keggin-type heteropolyoxometalates (POMs) (POMs sequentially refer to H 5 PMo 10 V 2 O 40 ·36H 2 O (PMoV), H 3 PMo 12 O 40 ·14H 2 O (PMo), H 4 SiMo 12 O 40 · x H 2 O (SiMo), and H 4 SiW 12 O 40 · x H 2 O (SiW)) in THF reveals that TPP evolves i…
Industrial production of magneto-sensitive nanoparticles, which can be used in the production of target drug delivery carriers, is a subject of interest for biotechnology and microbiology. Synthesis of these nanoparticles by microorganisms has been described only for bacterial species. At the same time, it is well kno…
Two types of magnetite (Fe3O4) hollow nanostructures, namely, nanoring (NR) and nanotube (NT), were fabricated by chemical method. The NR and NT exhibit a vortex and ferromagnetic domain structure, respectively, as revealed by 3D micromagnetic simulation. The measurement on microwave electromagnetic properties suggest…
An appropriate way of realizing property nanoengineering in complex quaternary chalcogenide nanocrystals is presented for Cu2CdxSnSey(CCTSe) polypods. The pivotal role of the polarity in determining morphology, growth, and the polytypic branching mechanism is demonstrated. Polarity is considered to be responsible for…
The photoemission spectrum of graphite is still debated. To help resolve this issue, we present photoemission measurements at high photon energy and analyze the results using a Green's function approach that takes into account the full complexity of the loss spectrum. Our measured data show multiple satellite replicas…
To research the relationship of micro-structures and antibacterial properties of the titanium-doped ZnO powders and probe their antibacterial mechanism, titanium-doped ZnO powders with different shapes and sizes were prepared from different zinc salts by alcohothermal method. The ZnO powders were characterized by X-ra…
As one of the most important two-dimensional (2D) materials, BN nanosheets attracted intensive interest in the past decade. Although there are many methods suitable for the preparation of BN sheets, finding a cheap and nontoxic way for their mass and high-quality production is still a challenge. Here we provide a high…
We investigated ultraviolet (UV) laser-induced degradation of nonlinear optical crystal CsLiB6O10 (CLBO) and β-BaB2O4 (BBO) using a high-repetition-rate pulsed laser. In this research, we found that the degradation of CLBO was caused by a UV-induced refractive index change at a peak power density higher than a few ten…
In this work we successfully controlled formation and alignment of a crystal superstructure in an isotactic polypropylene (iPP) pipe via self-assembly of a β nucleating agent and rotation extrusion to tailor the performances of the iPP pipe. The results showed that during iPP pipe extrusion, β nucleating agents first…
Metal nanoparticle (NP)-graphene multifunctional platforms are of great interest for exploring strong light-graphene interactions enhanced by plasmons and for improving performance of numerous applications, such as sensing and catalysis. These platforms can also be used to carry out fundamental studies on charge trans…
Poly(bisphenol A carbonate) (PC) was hydrolyzed in a benchtop fluidized bed reactor and compared with the pyrolysis of PC. Hydrolysis resulted in bisphenol A (BPA) and the cleavage of BPA in the formation of phenol and p -isopropenylphenol (IPP). Experiments were carried out using MgO or quartz sand (SiO 2 ) as bed ma…
Magnetic and electronic properties of Fe4N(111)/MoS2(√3 × √3) superlattices are investigated by first-principles calculations, considering two models: (I) Fe(I)Fe(II)-S and (II) N-S interfaces, each with six stacking configurations. In model I, strong interfacial hybridization between Fe(I)/Fe(II) and S results in mag…
Curcumin loaded poly(2-hydroxy ethyl methacrylate) p(HEMA) nanofiber were produced using electrospinning method and characterized. The nanofibrous scaffold supports good cell growth, attachment and retains its original morphology. Sustained and controlled release pattern of curcumin seen to be efficient against infect…
The micropackaging of chemical compounds in a small and precisely defined quantity, which can be encased, stored, is essential for response to a specific chemical, biological or physical trigger in a controllable manner is one of the premier challenges in the development of delivery systems.
