Abstract In the last few years, a new class of smart multifunctional photoelectrochemical devices has been attracting the interest of several academic institutions and industrial companies: photovoltachromic cells, combining the features of photoelectrochromic cells with those of dye‐sensitized solar cells. Here, we r…
The frequency of invasive fungal infections has rapidly increased in recent years. Current clinical treatments are experiencing decreased potency due to severe host toxicity and the emergence of fungal drug resistance. As such, new targets and their corresponding synthetic pathways need to be explored for drug develop…
Abstract Despite significant research efforts, designing bimetallic catalysts rationally remains a challenging task. Herein, we combine the strengths of high‐throughput experiments and DFT calculations synergistically to design new core–shell bimetallic catalysts. The total oxidation of propane is used as a probe, pro…
In this article we report Eu(3+) luminescence in novel K3 Ca2 (SO4 )3 Cl phosphors prepared by wet chemical methods. The Eu(3+) emission was observed at 594 nm and 615 nm, keeping the excitation wavelength constant at 396 nm nearer to light-emitting diode excitation, Furthermore, phosphors were characterized by X-ray…
Stimulated Raman scattering in silicon-rich silicon oxide (SiOx, x < 2) films annealed at 1200 °C is measured with excitation at 785 nm. Our main objective is to confirm giant Raman gain, recently reported in annealed SiOx films for excitation at ∼1500 nm. Another important aspect is the possibility of using SiOx film…
We demonstrate how a silver-nanowire-dimer can be employed to optically excite dual-path surface-plasmon-polaritons and utilize them to perform remote-excitation surface-enhanced Raman scattering (SERS) microscopy. Interestingly, this unique geometry allows us to perform dual-path remote-excitation SERS. Our experimen…

Well-defined semiconducting microelectrodes on silicon chips are prepared for new insights into microelectrode electrochemistry. Unique voltammetric features are observed due to a combined effect of enhanced mass transport from microelectrodes and rectifying nature of the semiconductor-electrolyte interface. The "diff…
Disordered systems show deviations from the standard Debye theory of specific heat at low temperatures. These deviations are often attributed to two-level systems of uncertain origin. We find that a source of excess specific heat comes from correlations between quanta of energy if excitations are localized on an inter…
In this letter, we investigate the correlated diffusion of colloidal particles in quasi two-dimensional monolayer near an oil-water interface for different distance between the interface and the particle monolayer z. It is found that there is a transition in the behavior of the correlated diffusion from the bulk domin…
Background: This experimental study aims to investigate whether basic fibroblast growth factor, adipose tissue-derived from mesenchymal stem cells, or a combination of both, has an effect on wound healing, epithelization and angiogenesis in a tracheal resection and end-to-end anastomosis rat model. Methods: During the…
The evolution of radiation-induced carbon-oxygen related defects with the fluence of MeV electrons and upon subsequent isochronal annealing (75-350 °C) in Si crystals with different carbon and oxygen content has been studied by means of Local Vibrational Mode (LVM) spectroscopy. In particular, the generation kinetics…
Characterization of Al2O3 gate dielectric on GaN using pulsed laser Atom Probe Tomography is reported. Atomic layer deposition was used to grow 5 nm of aluminum oxide on Ga-polar GaN. No oxidation of the surface of the semiconductor was observed and the interface was found to be non-abrupt. A significant amount of car…
In this study, 4‐thiophenol modified glassy carbon electrode was prepared by the reduction of 4‐diazothiophenol tetrafluoroborate salt. Silver nanoparticles were attached to the thiophenol modified surface to prepare a thiophenol‐silver nanoparticle composite film. 4‐Aminothiopenol molecules were deposited by self‐ass…
A thin quarter-wave plate and a half-wave plate are designed based on multiple antenna-array sheets (AAS). For transmission through cascaded antenna-array sheets, an equivalent transmission-line model is used. The interspacing dielectric is modeled as a transmission line with each AAS treated as a loaded shunt admitta…
ABSTRACT A hydrophobically modified polyacrylamide (PAM) was synthesized by the copolymerization of acrylamide (Am) and N‐hexadecylacrylamide (hAm) through solution copolymerization in a polar organic solvent. Polymer synthesis was performed in three nonaqueous media, including dimethyl sulfoxide (DMSO), a mixture of…
The aim of this study was to compare the specific characteristics of the S-enantiomer and the racemate of amlodipine besylate (AB) in order to design a robust and stable formulation of the active S-enantiomer which will guarantee continuous performance of the unichiral version of amlodipine. Preformulation studies sho…
The intensity-dependent nonlinear absorption and refraction characteristics of crystalline InSb thin films are investigated by z-scan method at 405 nm laser wavelength. Results show that the nonlinear absorption coefficient of crystalline InSb thin films is in the order of ∼ + 10 −2 m W −1 , and the nonlinear refracti…
Corrosive conditions in the BWR primary cooling system are usually expressed by the corrosion index, ECP. In order to determine ECP at any location in the primary cooling system, ECP should be evaluated by computer simulation codes consisting of water radiolysis models to determine the concentrations of corrosive radi…
A convenient scaffold based on poly(N-vinyl-2-pyrrolidone-co-vinyl alcohol) is proposed for presenting ligands in multivalent format. This amphiphilic polymer supports synthesis of conjugates in both organic and aqueous media, permits enzymatic processing of the ligand precursor, and, finally, offers a choice of forma…
