The Z-scheme has been proven to be an effective strategy to develop a high-efficiency visible-light photocatalyst. However, the visible-light-responding active component in the Z-scheme system is usually restricted to semiconductor materials sensitive to visible light. On the other hand, noble-metal nanoparticles (suc…
Firmly attached: The short-circuit photocurrent density and conversion yields of solar cells based on pyridine-containing donor–acceptor π-conjugated (D-π-A) dyes (see scheme) are greater than those for conventional D-π-A dye sensitizers that bear a carboxy group as the electron-withdrawing anchoring group. The dyes a…
The capabilities of using gold nanoparticle based surface-enhanced Raman spectroscopy (SERS) to obtain blood serum biochemical information for non-invasive colorectal cancer detection were presented in this paper. SERS measurements were performed on two groups of blood serum samples: one group from patients (n = 38) w…
An ab initio theory for Fano resonances in plasmonic nanostructures and metamaterials is developed using the Feshbach formalism. It reveals the role played by the electromagnetic modes and material losses in the system, and enables the engineering of Fano resonances in arbitrary geometries. A general formula for the a…
We introduce an ultrasensitive label-free detection technique based on asymmetric Fano resonances in plasmonic nanoholes with far reaching implications for point-of-care diagnostics. By exploiting extraordinary light transmission phenomena through high-quality factor (Q(solution) ∼ 200) subradiant dark modes, we exper…
A systematic study of the mechanisms of Au nanoparticle/TiO 2 -catalyzed photoreduction of CO 2 and water vapor is carried out over a wide range of wavelengths. When the photon energy matches the plasmon resonance of the Au nanoparticles (free carrier absorption), which is in the visible range (532 nm), we observe a 2…
Coordination polymers are currently one of the hottest topics in Inorganic and Supramolecular Chemistry. This critical review summarizes the current state-of-the-art on electrical conductive coordination polymers (CPs), also named metal-organic frameworks (MOFs). The data were collected following two sort criteria of…
A small change in the Hamiltonian scaling in Replica Exchange with Solute Tempering (REST) is found to improve its sampling efficiency greatly, especially for the sampling of aqueous protein solutions in which there are large-scale solute conformation changes. Like the original REST (REST1), the new version (which we…
Abstract The regeneration of Z‐cut KDP crystals is explored by analyzing the growth of thin surface layers formed. The structural defects and crystalline perfection of the thin surface layers are evaluated by white‐beam synchrotron radiation topography and high‐resolution X‐Ray diffraction respectively. It shows that…
An understanding of the conversion process from slurry to particle layer on a substrate is required for the precise control of the particle alignment and the material distribution in the coated slurry. In this work, variation of coated slurry thickness during drying was applied to evaluate drying and particle layer fo…
Cp verbindet: Lanthanoid-Übergangsmetall-Cluster mit Zweielektronen-Mehrzentren-Bindungen entstehen aus chiralen vierfach gebundenen Organolanthanoid-Komplexen, die über eine unverbrückte Metall-Metall-Bindung verfügen. Die Reaktion verläuft über C-H-Bindungsaktivierungen an polaren Metall-Metall-Bindungen und führt z…
Immer zu zweit: Rastertunnelmikroskopie/-spektroskopie (STM/STS) ergibt für den riesigen radförmigen Mo154-Cluster eine einzigartige Lokalisierung der Zustände in jedem der 14 identischen Kompartimente seiner halskettenartigen Struktur (siehe Bild). Jedes Kompartiment enthält zwei delokalisierte Elektronen. Damit unte…
We explore the relationship between the structural and magnetic properties of GaN/Fe core/shell nanowires grown epitaxially on Si substrates. The magnetic properties are consistent with the coexistence of two magnetic contributions: a ferromagnetic response from the single-crystalline Fe particles formed at the nanowi…
We study the effects of both convective and unsteady inertia on the dynamics and rheology of a dilute suspension of periodically forced neutrally buoyant spherical particles, at low Reynolds numbers, in a quiescent Newtonian fluid. The inclusion of inertia results in additional terms in the equation governing the dyna…
Abstract A series of four phosphonated‐bearing allyl monomers, that is, diethyl‐1‐allylphosphonate (AP), dimethyl‐1‐allyloxymethylphosphonate (AOP), 5‐ethyl‐5‐(allyloxymethyl)‐2‐oxo‐1,3,2‐dioxaphosphorinane (AEDPH), and 2‐benzyl‐5‐ethyl‐5‐(allyloxymethyl)‐2‐oxo‐1,3,2‐dioxaphosphorinane (AEDPBn) were synthesized. These…
The behavior of electromagnetic fields in nonlinear media has been a topical problem since the discovery of materials with a nonlinearity of electromagnetic properties. The problem of finding exact solutions for the source-excited nonlinear waves in curvilinear coordinates has been regarded as unsolvable for a long ti…
In this article, a semi-analytical finite element approach based on the nonlocal elastic shell model is proposed to study the thermal buckling of multiwalled carbon nanotubes (MWCNTs). By taking nonlocality into consideration, the small scale effect is incorporated into the model presented herein. Based upon the Ering…
Despite the great potential of the application of surface-enhanced Raman scattering (SERS), the difficulty in fabricating suitable SERS substrates is still a challenge. Based on the self-assembly of silica nanoparticles, the image shows a highly ordered, 3D petallike arrayed structure that serves as a promising SERS s…
Abstract Reinforcement of interfacial adhesion between syndiotactic polypropylene (SPP) and fibrous pure cellulose (FC) was performed by the FC silanizations with 3‐aminopropyltrimethoxysilane (APTMS), with hexyltrimethoxysilane (HTMS) and by an addition of a SPP grafted with dimethyl itaconate (SPP‐g‐DMI: number‐aver…
The electrochemical behavior of cysteine and cystine on carbon-paste electrodes modified with Fe(II), Co(II), Ni(II), and Cu(II) phthalocyanines is studied. Metal phthalocyanines exhibit catalytic activity in the electrooxidation of cysteine and cystine and in the reduction of cystine. The best catalyst is the cobalt…
