A highly selective fluorescent probe based on hydroxyphenyl-benzothiazole is synthesized which shows palladium-mediated cleavage to produce fluorescence changes at two different wavelengths in mixed aqueous media.
The influence of methyl paraben (MP) and butyl paraben (BP) on the aggregation characteristics of Pluronics in an aqueous medium has been investigated by DLS, SANS, viscometry, and fluorescence measurement techniques. Parabens are extensively used as preservatives in cosmetic, pharmaceutical, and food products. In thi…
We demonstrate that a carbon-bridged phenylenevinylene (CPV)-linked dye serves as a novel and efficient sensitizer for dye-sensitized solar cells. The cells show IPCE values of greater than 90%, PCEs of up to 7.12%, and high open circuit voltages reaching close to 0.8 V based on the iodide/triiodide electrolyte.
The effect of morphology of PNIPAm, PEGMa and PNIPAm-co-PEGMa hydrogels on the uptake and delivery (release kinetics) of a model drug (FITC–dextran) was investigated. Two types of hydrogel architectures: microgels and microcapsules, without and with core–shell morphology, were synthesized. The microcapsules had 30–50%…
Single-crystalline UGe${}_{2}$ was investigated by means of magnetic susceptibility, magnetization, electrical resistivity, magnetoresistivity, and specific-heat measurements, all carried out in wide temperature and magnetic-field ranges. An analysis of the obtained data points out the dual behavior of the 5$f$ electr…
The Knudsen diffusivity and viscous permeability of proton exchange membrane fuel cell microporous coated gas diffusion layers are obtained experimentally for different polytetrafluoroethylene loadings. Pressure drop across the microporous coated gas diffusion layers is measured at varying flow rates and using differe…
A series of new lipid prodrugs of paclitaxel, which can be formulated as nanoassemblies, are described. These prodrugs which are designed to overcome the limitations due to the systemic toxicity and low water solubility of paclitaxel consist of a squalene chain bound to the 2'-OH of paclitaxel through a 1,4-cis,cis-di…
An ensemble-based fluorescent sensor HS-1 + Cu(2+) for detection of histidine is reported. Complex HS-1 + Cu(2+) sensitively senses histidine at pH 7.4 in aqueous media. The quantitative determination of histidine in urine and fetal calf serum is also conducted.
The electrochemical behaviour of ferrocene (Fc) is investigated in six different deep eutectic solvents (DESs) formed by means of hydrogen bonding between selected ammonium and phosphonium salts with glycerol and ethylene glycol. Combinations of cyclic voltammetry and chronoamperometry are employed to characterise the…
Graphite-based electrodes (graphite, graphene, and nanotubes) are used widely in electrochemistry, and there is a long-standing view that graphite step edges are needed to catalyze many reactions, with the basal surface considered to be inert. In the present work, this model was tested directly for the first time usin…
Poly(acrylic acid-co-N,N'-methylenebisacrylamide) hydrogel films were synthesized by copolymerizing acrylic acid (AAc) with N,N'-methylenebisacrylamide (MBA) as a cross-linker via photo polymerization in the spacing confined between two glass plates. NMR spectroscopy was utilized to determine the cross-linking density…
Keratin is an important protein used for wound healing and tissue recovery. In this study, keratin was first extracted from raw materials and chemically modified to obtain stable keratin (m-keratin). The raw and m-keratin were examined by Raman spectroscopy. The molecular weight of the m-keratin was analysed by SDS-PA…
Herein we report the successful preparation of carrier free co-immobilized form of glucoamylase and pullulanase using combi-CLEAs method from commercial multi-enzyme preparation OPTIMAX® 7525 HP. Glucoamylase and pullulanase were precipitated using ammonium sulfate, followed by cross-linking for 8 h with 2% (v/v) glut…
Antennas convert propagating radiation to localized electromagnetic energy and to heat. To unambiguously separate between these two aspects, one needs to quantitatively determine the antenna scattering and absorption cross-section spectra. By using a spatial modulation technique combined with a common-path interferome…
A series of transition metal(M)-loaded TiO2 catalysts (M/TiO2) and Co-loaded catalysts on various support materials were prepared by an impregnation method, followed by in situ H2-reduction at 400 °C, and tested for the acceptor-free oxidation of cyclododecanol in the liquid phase. Among the catalysts including noble…
Myocardial infarction is a major cause of morbidity and mortality worldwide. However, the methodological development of a spatiotemporally controllable investigation of the damage events in myocardial infarction remains challengeable. In the present study, we describe a micropillar array-aided tissue interface mimicki…
In recent years, microfluidic systems have been used to study fundamental aspects of angiogenesis through the patterning of single-layered, linear or geometric vascular channels. In vivo, however, capillaries exist in complex, three-dimensional (3D) networks, and angiogenic sprouting occurs with a degree of unpredicta…
A new occupancy model for predicting the crystal morphologies influenced by solvent and temperature is proposed. In the model, the attachment energy is corrected by a relative occupancy, which is the occupancy of a solute molecule relative to the total ones of a solute molecule and a solvent molecule. The occupancy is…
Aluminum nanoparticles (Al-NPs) and nano-Al/CuO thermite were investigated in a rapid heating environment by temperature jump time-of-flight mass spectrometry. Upon rapid heating (10 5 to 10 6 K/s), Al-containing vapor species (Al and Al 2 O) are observed to slowly increase with increasing temperature, followed by a r…
Numerical simulations of soot formation of n-heptane autoigniting spray in a constant-volume vessel under diesel engine conditions with different ambient densities (14.8 and 30 kg/m3) and ambient oxygen concentrations (8–21% O2 mol fraction) were performed using two-dimensional, first-order conditional moment closure…
