A novel time-resolved luminescence biosensor assay for anaplastic lymphoma kinase (ALK) was developed. We used a straightforward strategy to modify a known ALK substrate into a peptide biosensor that can accommodate terbium luminescence sensitization upon its phosphorylation by ALK. Since this strategy is generalizabl…
Non-selective luminescence spectroscopy and luminescence line-narrowing spectroscopy were used to study the retention of UO2(2+) on titanium dioxide (TiO2), synthetic calcium silicate hydrate (C-S-H) phases and hardened cement paste (HCP). Non-selective luminescence spectra showed strong inhomogeneous line broadening…
We report on the development of a high-resolution see-through integral imaging system with a resolution and fill factor-enhanced lens-array holographic optical element (HOE). We propose a procedure for fabricating of a lens pitch controllable lens-array HOE. By controlling the recording plane and performing repetitive…
Photocatalytic oxidation of organic compounds proceeded efficiently in a hybrid system with ruthenium aqua complexes as catalysts, BiVO4 as a light absorber, [Co(NH3)5Cl](2+) as a sacrificial electron acceptor and water as an oxygen source. The photogenerated holes in the semiconductor are used to oxidize molecular ca…
We have developed two novel synthetic methods, by which two types of mononuclear Fe model complexes for the active site of [Fe]hydrogenase are successfully synthesized. The first type of 2-acylmethyl-6-hydroxymethylpyridine-containing complexes, [2-COCH 2 -6-HOCH 2 C 5 H 3 N]Fe(CO) 2 G ( 1, G = PhCO 2; 2, PhCOS; 3, Ph…
The synthesis and analysis of the electronic states of the main-chain type-organogallium polymers are presented. We synthesized the polymers containing four-coordinate gallium atoms by organometal coupling reactions. The synthesized polymers showed good solubility in common organic solvents and enough stability for me…
We study the 2D crystalline phases of paramagnetic colloidal particles with dipolar interactions and constrained on a periodic substrate. Combining theory, simulation, and experiments, we demonstrate a new scenario of first-order phase transitions that occurs via a complete inversion of the energy landscape, featuring…
Nine cyclometalated ruthenium complexes with a redox-active diphenylamine unit in the para position to the RuC bond were prepared. MeO, Me, and Cl substituents on the diphenylamine unit and three types of auxiliary ligands-bis(N-methylbenzimidazolyl)pyridine (Mebip), 2,2':6',2''-terpyridine (tpy), and trimethyl-4,4',…
Lithium terephthalate (Li2C8H4O4, PTAL), a carboxylate-based organic electrode material, displays high reversible capacity of up to 248 mA h g−1 and long cycle life, which is promoted by graphene as a sustainable anode material for lithium ion batteries.
Fabry-P\'erot interference, measured as conductance oscillations, can be used to search for anyons such as Majorana bound states. The first observation of Fabry-P\'erot interference in a topological insulator has now been reported.
Three-dimensional (3D) asymmetric plasmonic structures possessing asymmetric optical transmission properties have been widely studied. However, these structures have limitations for application due to fabrication techniques. Here, a quasi-3D asymmetric structure built up by a metallic rod-shaped particles layer and a…
Hyaluronan (HA) is a naturally occurring glycosaminoglycan widely researched for its use as a biomaterial in tissue engineering, drug delivery, angiogenesis, and ophthalmic surgeries. The mechanical properties of this biomaterial can be altered to a required extent by chemically modifying the pendant reactive groups.…
Abstract Cobalt‐incorporated nitrogen‐doped reduced graphene oxide (Co/NrGO) as a catalyst for the oxygen reduction reaction is prepared in a single step by thermal reduction of graphene oxide to reduced graphene oxide (rGO) in the presence of a cobalt salt and 1,10‐phenanthroline as a nitrogen precursor. Cobalt is id…
Journal of Physical Science and Application provides an international medium for the studies related to the experimental and theoretical studies in physical science. We welcome contributions which promote the exchange of ideas and rational discourse between practicing educators and material researchers all over the wo…
We performed positron annihilation spectroscopy measurements on uranium dioxide irradiated with 45 MeV $\ensuremath{\alpha}$ particles. The positron lifetime was measured as a function of the temperature in the 15--300 K range. The experimental results were combined with electronic structure calculations of positron l…
A strong microwave shielding effect due to the excitation of microwave eddy-currents exists for metallic films of sub-skin-depth thickness (10–100 nm). If the film is ferromagnetic, this effect strongly influences results of the broadband stripline ferromagnetic resonance (FMR) spectroscopy. It also potentially hamper…
The efficient synthesis has been disclosed to achieve a new class of ladder-type molecules, B,S-bridged p-terphenyls (BS-TPs). Their properties were fully characterized by UV-vis and fluorescence spectroscopy in both solution and solid state, time-resolved fluorescence spectroscopy, DFT theoretical calculations, and c…
Abstract In this study, we synthesized two types of calcium sulfonate complex greases (barium soap and calcium soap) and investigated their physical, rheological, and tribological properties in detail. The test results showed that the evolution of their linear viscoelasticity functions with frequency were quite simila…
Originating from the reactive halogenated iPPs, diverse side-group and graft functionalized polypropylenes were synthesized via thiol–halogen nucleophilic substitution click chemistry.
Solar-driven photocatalytic process based on electron-hole pair production in semiconductors is a long sought-after solution to a green and renewable energy and has attracted a renaissance of interest recently. The relatively low photocatalytic efficiency, however, is a main obstacle to their practical applications. A…
