We demonstrate that the performances of dye-sensitized solar cells (DSCs) sensitized with a previously reported N-heterocyclic carbene iron(II) dye in the presence of chenodeoxycholic acid co-adsorbant, can be considerably improved by altering the composition of the electrolyte while retaining an I−/I3− redox shuttle.…
Abstract The nearly hemispherical field of view (FOV) of arthropodal compound eyes has inspired analogs ranging from curved, lens‐patterned domes to planar constructs patterned with microlenses. A radial distribution of cylindrical waveguides that monotonically spans ±33° confers an FOV of 115° to a slim (≤3 mm) polym…
Quorum sensing (QS) plays an important role in the growth, nodulation, and nitrogen fixation of rhizobia. In this study, we show that water-soluble humic materials (WSHM) repress the expression of the QS related genes sinI, sinR, and expR in Sinorhizobium meliloti. This decreased the production of N-acetyl homoserine…
Abstract Zinc phthalocyanine derivatives, 1 and 2 , having either electron donating octyl‐thiol group or electron accepting octyl‐sulfonyl groups have been synthesized to serve as new electron donor components for bulk heterojunction (BHJ) solar cells. BHJ solar cells, in which the active layer consist of zinc phthalo…
The nucleation and grain growth that occur during solidification have been extensively examined, but insight into the influence of an external field on the formation of heterogeneous crystal nuclei above the liquidus remains unclear in the peritectic refinement mechanism. In this work, we studied the effect of cooling…
Abstract Photopolymerisation, oder in anderen Worten die Nutzung von Licht als Auslöser einer Polymerisationsreaktion, ist eine der vielversprechendsten Technologien zur Herstellung anspruchsvoller Polymere. Eine der Schlüsselkomponenten der Photopolymerisation ist die photoaktive Spezies. Diese ist in der Lage, durch…

The present study investigates heat transfer enhancement of natural convection in an air-filled enclosure by a nonsymmetric electric field. The geometry considered is a two-dimensional cavity with an aspect ratio of five. The electrical field is generated from a wire electrode charged with a high voltage of direct cur…
Environmental impacts of continued CO2 production have led to an increased need for new methods of CO2 removal and energy development. Electrochemical reduction of CO2 has been shown to be a good method through recent studies. Alloys are of special interest for these applications, because of their unique chemical and…
We proposed an approach to get multiple and adjustable optical Tamm states (OTSs) by constructing a structure consisting of a metal layer and one-dimensional photonic quasicrystals with preassigned bandgaps. In the structure, multiple OTSs excited simultaneously in each bandgap were observed. We explored the physics m…
The objective of this study was to achieve an optimal formulation of hydrophilic-hydrophobic conjugates for nano-sized solid dispersions (SDs) with enhanced dissolution of multiple drugs in different gastrointestinal (GI) tract environments. A new conjugate powder with an optimized process was used to fabricate SDs th…
The broadband nonlinear absorption in ZnO nanocrystals embedded in Al2O3 matrix was investigated by Z-scan and pump–probe techniques from 400 nm to 800 nm. The effective two-photon absorption and three-photon absorption coefficients were determined to be ∼1.1×103 cm/GW at 400 nm and ∼1.1×10−1 cm3/GW2 at 800 nm, respec…
The annealing process of cold-rolled ferrite/pearlite steel involves numerous metallurgical mechanisms as recovery/recrystallization of deformed phases, ripening of carbide microstructure, and austenite transformation in the intercritical domain. The interactions between these mechanisms govern the morphogenesis of th…
Nanostructured tungsten trioxide porous films were prepared by a non-hydrolytic sol⁻gel method following the inorganic route in which ethanol and PEG were used as the oxygen-donor and structure-directing reagent, respectively. The effects of aging time of the precursor solution, PEG content, and calcination temperatur…
We report on anomalous structure and relaxation features of the aggregate clusters fostered in a representative series of dilute poly(3-hexylthiophene)/chlorobenzene (P3HT/CB) solutions (3, 5, 8, and 10 mg/mL), as resolved by multiscale dynamic/static analysis schemes including depolarized/polarized dynamic light scat…
Porous carbons have been widely utilized as electrode materials for capacitive energy storage. Whereas the importance of pore size and geometry on the device performance has been well recognized, little guidance is available for identification of carbon materials with ideal porous structures. In this work, we study th…
Abstract We report on a high-quality p -GaN metal-insulator-semiconductor (MIS) capacitors with sharp interface morphology and the lowest interface trap density by using SiN x as the gate dielectric layer. Transmission electron microscopy and x-ray photoelectron spectroscopy (XPS) analysis revealed a high-quality inte…
Additives to polymer materials allow to obtain a wide range of functional properties. The improvement of wear and durability of plastics is achieved by the use of powder or fibrous fillers and complex modifications of structure. The aim of the work was to examine the physical, mechanical and tribological properties of…
Nature's motors are complex and efficient systems, which are able to respond to many different stimuli present in the cell. Nanomotors for biomedical applications are designed to mimic nature's complexity; however, they usually lack biocompatibility and the ability to adapt to their environment. Polymeric vesicles can…
Abstract Pear pomace (PP) is a by‐product of the fruit industry with a high content of fibre. Its potential as an ingredient at 15% or 30% level for sponge and layer cakes was investigated. Three PP powders with different particle sizes (fine, medium and coarse) were obtained. Batter microstructure, density and viscos…
