ABSTRACT: Effects of lactoferrin (LF), lactoferrin hydrolysate (LFH), and lactoperoxidase systems (LPOS), both directly and incorporated into edible whey protein isolate (WPI) films, on the inhibition of Penicillium commune were studied. Mechanical, oxygen‐barrier, and color properties of WPI films with and without LP…
Liquid-core capsules have wide-ranging applications in the high-efficiency encapsulation and controlled release of drugs, dyes, enzymes, and other substrates. Their great utility has driven the rapid development of various preparation techniques. However, there remains no convenient technique for the preparation of su…
Investigation of the growth of CdSe nanocrystals ( approximately 160 atoms) to the uniquely stable size of 2 nm allows the monitoring of the crystallization process in semiconductor quantum dots. By using a combination of optical techniques, high-resolution transmission electron microscopy (HRTEM), and powder X-ray di…
We examine via molecular simulation the dependence of the crystal-melt interfacial free energy $\ensuremath{\gamma}$ on molecular interaction and crystal structure (fcc vs bcc) for systems interacting with inverse-power repulsive potentials, $u(r)=ϵ(\ensuremath{\sigma}/r{)}^{n}$, $6\ensuremath{\le}n\ensuremath{\le}100…
The substrates for Bacillus subtilis PLP synthase (YaaD and YaaE) are identified, and the first reconstitution of PLP biosynthesis using this pathway is described. Three partial reactions catalyzed by YaaD are also identified.
BACKGROUND: Nephrogenic fibrosing dermopathy (NFD) is a recently described cutaneous fibrosing disorder associated with renal dysfunction. Patients present with thickened skin or oedematous skin with indurated papules and plaques involving extremities and trunk, and often associated with disabling contracture of the a…
Ultra‐high temperature ceramics (UHTCs) exhibit a number of properties (thermal and chemical stability, high strength and hardness, ablation/oxidation and thermal shock resistance) for sustained use in the extreme environments experienced by re‐entry space vehicles. The spark plasma sintering (SPS) was considered as a…
Abstract Recognizing microbial imprints in the morphology of calcium carbonate minerals that form in very supersaturated solutions containing a high level of dissolved inorganic carbon (DIC) is challenging. To better define criteria for this purpose, we have analyzed the influence of sulfate-reducing bacterium Desulfo…
Single-phase bulk Cr2AlC, a non-Ti-containing carbide with superior expected properties, was successfully fabricated by in-situ hot pressing/solid-liquid reaction process. The reaction process was investigated using differential scanning calorimetry. The products were characterized using X-ray diffraction and scanning…
Phasins play an important role in the formation of poly(3-hydroxybutyrate) [poly(3HB)] granules and affect their size. Recently, three homologues of the phasin protein PhaP1 were identified in Ralstonia eutropha strain H16. The functions of PhaP2, PhaP3 and PhaP4 were examined by analysis of R. eutropha H16 deletion s…
We report experimental results on the structural, magnetic, electronic, and spin transport properties of a $21\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ ${\mathrm{Fe}}_{3}\mathrm{Si}∕\mathrm{GaAs}(001)$ heterostructure epitaxially grown by coevaporation. High-resolution x-ray diffraction shows an almost stoichiometric fi…
Abstract BaXO 4 (X = Mo, W) nanobelts and a variety of hierarchical superstructures assembled from the nanobelts have been synthesized in a catanionic reverse‐micelle system. The effects of various factors, such as the mixing ratio ( r ) between the anionic and cationic surfactants, the temperature, and the presence o…
One-dimensional colloidal metal oxide nanocrystals are of great importance in materials chemistry, but reports on these materials are rare due to lack of well-defined synthetic protocols. In this paper, we present a general and highly effective one-pot synthetic protocol to produce 1-dimensional nanostructures of tran…
Recent widespread interest in the development of engineered tissue and organ replacement therapies has prompted demand for new approaches to immobilize exogenous components to natural collagen. Chemical coupling of synthetic moieties to amino acid side chains has been commonly practiced for such purposes; however, suc…
ABSTRACT: The inhibitory activity of chitosan‐based edible coatings and films was assessed against the Aspergillus niger food pathogen and deterioration microorganism. Spore‐counting assays showed an almost total inhibition of A. niger growth when either film‐forming solution or film were used at a low concentration o…
Asymmetric end-functionalization of carbon nanotubes was achieved by sequentially floating a substrate-free aligned carbon nanotube film on two different photoreactive solutions with only one side of the nanotube film being contacted with the photoreactive solution and exposed to UV light each time. The resultant nano…
Magnetoelectric interactions have been investigated in a single crystal of gadolinium iron borate GdFe 3 (BO 3 ) 4 , whose macroscopic symmetry is characterized by the crystal class 32. Using the results of this study, the interplay of magnetic and electric orderings occurring in the system has been experimentally rev…
Abstract Polypyrrole (PPy)/poly(methyl methacrylate) (PMMA) core/shell nanospheres with diameters of several tens of nanometers have been synthesized by two‐step microemulsion polymerization, and highly transparent conductive thin films have been fabricated using the nanospheres as a filler in a PMMA matrix. The PPy/P…
Spiders spin up to seven different types of silk and each type possesses different mechanical properties. The reports on base sequences of spider silk protein genes have gained importance as the mechanical properties of silk fibers have been revealed. This review aims to link recent molecular data, often translated in…
We have studied the phase transformation kinetics occurring in aluminum alloys containing Mn, Mg, and Mn-Mn-Mg by means of electrical resistivity (rho) and thermoelectric power (deltaS). The alloy samples were annealed isochronally at temperatures ranging from ambient temperature to 615 °C. Both rho and deltaS allowed…
