We introduce a new approach to improve structural and dynamical determination of large metalloproteins using solid-state nuclear magnetic resonance (NMR) with (1)H detection under ultrafast magic angle spinning (MAS). The approach is based on the rapid and sensitive acquisition of an extensive set of (15)N and (13)C n…
Isostructural cubane-shaped catalysts [Co(III)(4)(μ-O)(4)(μ-CH(3)COO)(4)(p-NC(5)H(4)X)(4)], 1-X (X = H, Me, t-Bu, OMe, Br, COOMe, CN), enable water oxidation under dark and illuminated conditions, where the primary step of photoinduced electron transfer obeys to Hammett linear free energy relationship behavior. Ligand…
ABSTRACT We report on improvements to the energy conversion efficiency of wide bandgap (Eg > 1.2 eV) solar cells on the basis of CuIn1−xGaxSe2. Historically, attaining high efficiency (>16%) from these types of compound semiconductor thin films has been difficult. Nevertheless, by using (a) the alkaline‐containing hig…
Patterned metal-organic framework, ZIF-8 thin films can be generated by using standard photolithography or via selective growth with the aid of microcontact printing. The alternate chemical deposition (of ZIF-8) and physical deposition (of metallic materials) allow the insertion of metal layers in the ZIF-8 film that…
Engineered nanomaterials offer numerous and tantalizing opportunities in many sectors of society, including medicine. Needless to say, attention should also be paid to the potential for unexpected hazardous effects of these novel materials. To date, much of the nanotoxicology literature has focused on the assessment o…
Active sites and structure–activity relationships for methanol synthesis from a stoichiometric mixture of CO 2 and H 2 were investigated for a series of coprecipitated Cu-based catalysts with temperature-programmed reduction (TPR), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron sp…
Novel theranostics based on photosensitizer-conjugated carbon dots is reported. The prepared C-dots–Ce6 has good stability and high water dispersibility and solubility, non-cytotoxicity, good biocompatibility, enhanced photosensitizer fluorescence detection and remarkable photodynamic efficacy upon irradiation. The C-…
Solid films are usually metastable or unstable in the as-deposited state, and they will dewet or agglomerate to form islands when heated to sufficiently high temperatures. This process is driven by surface energy minimization and can occur via surface diffusion well below a film's melting temperature, especially when…
Abstract The short peptides that specifically bind to SnO2 nanoparticles (NPs) were selected by using a phage display method. After the fourth round selection, ten kinds of amino acid sequences were identified, and it was revealed that affinities of the obtained phages for SnO2 NPs were relatively higher than that of…
Single-walled carbon nanotube:poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) hybrid film (SWCNT:PEDOT/PSS) hybrid conducting film was obtained by using spray-coating technique, based on which a white flexible organic light emitting diode (FOLED) was fabricated with the structure of SWCNT:PEDOT/PSS/N,N-diphen…
We report on a demonstration of top-gated graphene field-effect transistors (FETs) fabricated on epitaxial SiC substrate. Composite stacks, benzocyclobutene and atomic layer deposition Al 2 O 3 , are used as the gate dielectrics to maintain intrinsic carrier mobility of graphene. All graphene FETs exhibit n-type trans…
Abstract In order to obtain a high quality protective plating coating on Mg–16Li–5Al–0.5RE alloy, a zinc dipping technique at room temperature was investigated. The zinc dipping technique included two immersion processes, the primary immersion process and the secondary immersion process. Primary zinc transition layers…
Electron paramagnetic resonance and optical absorption studies of Bi2O3-ZnO-B2O3-Li2O glasses were made by introducing Cu2+ as spin probe. The EPR spectra of Cu2+ in all the glass samples recorded in the X-band frequency have similar spectral features. The variation in glass composition influences the spin Hamiltonian…
A simple approach is discussed to synthesise CdS nanoparticles using various pure alcohols and their mixtures with water as a reaction medium. The study highlights that the solvent plays an effective role not only in controlling the particle size but also the structure. The size and phase of CdS nanoparticles were con…
Abstract Tethering oligopeptides through one end densely packed onto a linear polymer main chain will greatly reduce freedom of the peptide chains, which affords an easy access to investigate the secondary structure of peptides under constrained condition. Herein, molecular brushes with densely grafted monodispersed C…
To improve the mechanical properties, the castability as well as the corrosion resistance of magnesium alloys, aluminium is frequently employed. As a rule, technically relevant alloys contain between 3 and 9 wt% aluminium. Normally, aluminium contents under 3 wt% is said to have no corrosion reducing effect. In order…
The facile synthesis of tetrapod‐like TiN nanocrystals with a hollow and porous structure is described. The nanocrystals were prepared by nitridation of a ZnO / TiO 2 core/shell structure consisting of a thin shell of tiny TiO 2 nanoparticles deposited onto a tetrapod‐like ZnO core by a vapor‐hydrolysis process. The Z…
In Bi(2)Te(3) materials the natural nanostructure (nns) with a wavelength of 10 nm can be reproducibly switched ON and OFF by Ar(+) ion irradiation at 1.5 and 1 keV. Controlled formation of the nns in Bi(2)Te(3) materials has potential for reducing its thermal conductivity and could increase the thermoelectric figure…
A new additive, Cobalt (Co)12-hydroxyl oleate, was successfully synthesized and its performance on the photodegradability of polypropylene (PP) film was evaluated by observing the disparity in the structural characteristics, surface morphology, mechanical, flow rate, molecular weight measurement, thermal gravimetric a…
We found that substitution of not only a larger ion like Ba 2+ [J. Am. Ceram. Soc., 93, 138 (2010)] but also a smaller one like Mg 2+ (this paper) replacing no >14.9% Ca 2+ ions could enhance integrated down‐shifting ( DS ) emission intensity of red phosphor Ca 3 ( VO 4 ) 2 :0.12 Eu 3+ , indicating that both lattice e…
