Carrier-free drug-eluting stents (DES)-based crystalline coatings are gaining prominence because of their function, skipping many limitations and clinical complications of the currently marketed DES. However, their usage has been humbled by inflexibility of the crystalline coating and limited mechanical and physical p…
We present the results of $^{75}\mathrm{As}$ nuclear magnetic resonance (NMR), nuclear quadrupole resonance (NQR), and resistivity measurements in ${\mathrm{KFe}}_{2}{\mathrm{As}}_{2}$ under pressure ($p$). The temperature dependence of the NMR shift, nuclear spin-lattice relaxation time (${T}_{1}$), and resistivity s…
Ti3AlC2/Al2O3 composite materials were successfully fabricated from TiO2/TiC/Ti/Al powders by the in situ reactive hot pressed technique. The microstructure, mechanical and oxidation properties of the composites were investigated in the paper. Vickers hardness increased with the Al2O3 content. The relative density of…
Molecular dynamics simulations of interacting soft disks confined in a heterogeneous quenched matrix of soft obstacles show dynamics which is fundamentally different from that of hard disks. The interactions between the disks can enhance transport when their density is increased, as disks cooperatively help each other…
Partial discharge (PD) measurement is one of the best methods for condition monitoring of transformers. In this paper, we use 5 different types of defects as follows: scratch on winding insulation, bubble in oil, moisture in insulation paper, a very small free metal particle in the transformer tank, and a fixed sharp…
Abstract The molding of food products causing health risks is a main problem in the food industry. In this study, as an alternative solution for preventing mold growth, an antifungal edible film was developed by incorporating Williopsis saturnus var. saturnus (0; 3; 7; and 9 logs CFU/cm 2 ) into whey protein concentra…
Capturing cell-secreted extracellular matrix (ECM) proteins through cooperative binding with high specificity and affinity is an important function of native tissue matrices during both tissue homeostasis and repair. However, while synthetic hydrogels, such as those based on poly(ethylene glycol) (PEG), are often prop…
Graphite oxide is synthesized via oxidation reaction using oxidant compounds that have lattice defects by the incorporation of unlike functional groups. Herein, we report the synthesis of the graphite oxide with diverse surface oxygen content through three (B, C, D) different modified versions of the Hummers method as…
ABSTRACT Novel tetra‐armed star‐shaped styrenic copolymers with pyrene side groups [ (S1‐S3)‐Pyr ] were prepared and employed as fluorescence sensing probe for fast and sensitive determination of nitroaromatic compounds. (S1‐S3)‐Pyr depicted characteristic pyrene monomer emission signals as well as broad excimer bands…
The advancement of SERS as an analytical tool requires substrates that provide both sensitive and reproducible measurements. In this work, a gold–titanium dioxide–gold metal–insulator–metal capped polymer nanopillar array SERS substrate is presented and optimized for SERS-based biosensing applications. The optical pro…
Abstract Aerobic catalytic oxidations are promising routes to replace environmentally harmful oxidants with O 2 in organic syntheses. Here, we report a molecular barium vanadium oxide, [Ba 4 (dmso) 14 V 14 O 38 (NO 3 )] (= {Ba 4 V 14 } ) as viable homogeneous catalyst for a series of oxidation reactions in N , N ‐dime…
It has been hypothesized that alkyl chains are inactive for electron transport processes through the chains. However, our theoretical study unveiled that loop-like alkyl chains can accelerate the electron transfer of triplet–triplet annihilation (TTA) through overlap of the pseudo π-orbital of the alkyl chain. The TTA…
The search for a catalyst for the reduction of nitrous oxide (N 2 O) is now imperative, as this molecule is a very dangerous pollutant. We found that the low-symmetry Pt 8 cluster presents multiple reaction pathways for N 2 O rupture, which are regioselective. This result was revealed by means of density functional th…
Carbon nanomaterials such as carbon blacks are intrinsically hydrophobic with limited wettability in aqueous media, thus restricting their potential applications. To improve their hydrophilicity, common methods tend to utilize harmful chemicals and conditions, such as a mixture of KMnO4 and H2SO4 or a complex and expe…
We present a continuous surface-potential-based compact model for molybdenum disulfide (MoS2) field effect transistors based on the multiple trapping release theory and the variable-range hopping theory. We also built contact resistance and velocity saturation models based on the analytical surface potential. This mod…
Recognition of single quantum dots (QDs) from high multi-exciton emission and clustering effects is challenging using the conventional second-order correlation function method. Here we demonstrate a method for fast recognizing single QDs based on the probabilities of detecting single- and two-photon events. The time-t…
The uracil permease UraA of Escherichia coli is a structurally known prototype for the ubiquitous Nucleobase-Ascorbate Transporter (NAT) or Nucleobase-Cation Symporter-2 (NCS2) family and represents a well-defined subgroup of bacterial homologs that remain functionally unstudied. Here, we analyze four of these homolog…
Epoxy coatings incorporating different content of sulfosalicylic acid doped polyaniline (PANI-SSA) have been investigated for corrosion protection of 5083 aluminum alloy in 3.5% NaCl solution. The performance of the coatings is studied using a combination of electrochemical impedance spectroscopy (EIS), open circuit p…

The product is a fine powder of particles having an av…
ABSTRACT In this study, we synthesized poly(methyl methacrylate) (PMMA) epoxy vitrimer composites by doping methyl methacrylate (MMA) and benzoyl peroxide into a curing system of epoxy resin and citric acid. The vitrimer composites were characterized with dynamic mechanical thermal analysis, scanning electron microsco…
