Fibrillar forms of the Amyloid‐β (Aβ) protein have been implicated in the early stages of Alzheimer's disease (AD), however there are no standardised assays for soluble Aβ oligomer biomarkers that provide the best indication of the disease progression [1,2]. As a step towards a fast and label‐free method for testing d…
Solubilities are reported for acenaphthene, fluoranthene, benzil, 9-fluorenone, trans-stilbene, phenothiazine, 2-methylbenzoic acid, 3-methylbenzoic acid, 4-chlorobenzoic acid, 3-nitrobenzoic acid, 4-nitrobenzoic acid, 3,4-dichlorobenzoic acid, 3,5-dinitrobenzoic acid, 2-chloro-5-nitrobenzoic acid, and 4-chloro-3-nitr…
The work in this investigation deals with the syntheses, characterization, crystal structures and catechol oxidase activity of four diphenoxo-bridged Co(III)Co(III) compounds of composition [Co(III)Co(III)L(Me-pn)(N3)4]·6H2O (), [Co(III)Co(III)L(Me-pn)(N3)4]·4H2O (), [Co(III)Co(III)L(Et-pn)(N3)4]·3.5H2O () and [Co(III…
The formation of the porous structure in dc magnetron sputtered amorphous silicon thin films at low temperatures is studied when using helium and/or argon as the processing gas. In each case, a-Si thin films were simultaneously grown at two different locations in the reactor which led to the assembly of different poro…
Red/blue shifts of laser-induced fluorescence (LIF) are investigated using several guest dielectric nanoscatterers, such as TiO2, ZnO, Al2O3, and SiO2, in the host Rd6G, RdB, Coumarin 4, and Coumarin 7 ethanolic solutions. A couple of inflection points are identified varying nanoparticle (NP) density into dye solution…
The thermal stability of the magnetic nano-skyrmion lattice in the monolayer Fe/Ir(111) is investigated using temperature dependent spin-polarized scanning tunneling microscopy. Our experiments show that the skyrmion lattice disappears at a temperature of T_{c}=27.8 K, indicating a loss of long-range magnetic order. A…
The effect of palladium doping of zinc oxide nanoparticles on the photoluminescence (PL) properties and hydrogen sensing characteristics of gas sensors is investigated. The PL intensity shows that the carrier dynamics coincides with the buildup of the Pd-related green emission. The comparison between the deep level em…
Cost effective and efficient methods for CO2 capture are the need of the hour to render the clean environment in the era of rising energy demand. Here, we report the physicochemical adsorption of carbon dioxide (CO2) in iron oxide decorated graphene nanocomposite at elevated pressures and temperatures. Nanocomposite w…
A simple yet scalable strategy for fabricating dry adhesives with mushroom-shaped micropillars is achieved by a combination of the roll-to-roll process and modulated UV-curable elastic poly(urethane acrylate) (e-PUA) resin. The e-PUA combines the major benefits of commercial PUA and poly(dimethylsiloxane) (PDMS). It n…
Using extensive classical molecular dynamics simulations, we compute the dielectric and far-infrared spectra of nine popular water models, including polarizable and nonpolarizable ones. We analyze the dielectric spectra using a two-relaxation model that allows one to extract the characteristic time of both the main di…
Ethane is oxidatively dehydrogenated with a selectivity up to 95% on catalysts comprising a mixed molten alkali chloride supported on a mildly redox-active Dy2O3-doped MgO. The reactive oxyanionic OCl(-) species acting as active sites are catalytically formed by oxidation of Cl(-) at the MgO surface. Under reaction co…
Time- and angle-resolved two-photon photoemission (2PPE) was used to study the electronic structure and ultrafast electron dynamics of the $p$-doped topological insulator ${\mathrm{Sb}}_{2}{\mathrm{Te}}_{3}$ and its derivative ${\mathrm{Sb}}_{2}{\mathrm{Te}}_{2}\mathrm{S}$. Our 2PPE experiments directly reveal that th…
Abstract New electrolyte solutions for rechargeable magnesium metal batteries were studied. The electrolyte solution composed of triethylene glycol dimethyl ether (triglyme) and butyl methyl triglyme as solvents and magnesium(II) bis(trifluoromethanesulfonyl)amide as a magnesium salt. The reversible deposition and dis…
Experiments demonstrating the controlled growth of oxide heterostructures have raised the prospect of realizing topologically nontrivial states of correlated electrons in low dimensions. Here, we study heterostructures consisting of {111} bilayers of double perovskites separated by inert band insulators. In bulk, thes…
Parasteatoda tepidariorum is an increasingly popular model for the study of spider development and the evolution of development more broadly. However, fully understanding the regulation and evolution of P. tepidariorum development in comparison to other animals requires a genomic perspective. Although research on P. t…
The g-C3N4/BiIO4 composite photocatalysts were successfully synthesized using a simple-mixed-calcinations method, and their photocatalytic activities for degradation of rhodamine B (RhB) under visible-light (λ > 420 nm) were investigated for the first time. The crystal structure and optical property of the as-synthesi…
Delayed wound healing will result in the development of chronic wounds in some diseases, such as diabetes. Amphibian skins possess excellent wound-healing ability and represent a resource for prospective wound-healing promoting compounds. A potential wound-healing promoting peptide (CW49; amino acid sequence APFRMGICT…
The effect of iridium valence in Ir:SrTiO 3 on the electronic structure and the photocatalytic activity in a water splitting reaction was studied. Epitaxial thin film photoelectrodes were grown with controlled Ir valence and used to measure the electrochemical efficiency of Ir:SrTiO 3 . The positions of the in-gap Ir…
Hyperdoping silicon nanocrystals (Si NCs) to a concentration exceeding the solubility limit of a dopant may enable their novel applications. Here, the successful hyperdoping of Si NCs with boron (B) and phosphorus (P) is demonstrated, which are the most important dopants for Si. Despite the hyperdoping, the diamond st…
