BACKGROUND: Functional properties of wheat starches with different particle size distribution were investigated. RESULTS: A-granules displayed a disc shape and B-granules displayed a spherical shape. A-granules had the highest conclusion temperature (Tc , 80.28 °C) and gelatinisation enthalpy (3.268 J g(-1)) and B-gra…
Effects of Mg substitution on order/disorder transition, microstructure, and microwave dielectric characteristics of Ba (( Co 0.6 Zn 0.4 ) 1/3 Nb 2/3 ) O 3 complex perovskite ceramics have been investigated. The ordered complex perovskite solid solutions are obtained in Ba (( Co 0.6− x /2 Zn 0.4− x /2 Mg x ) 1/3 Nb 2/…
An aptamer-linked graphene oxide (GO) microarray is synthesized for multiplex heavy metal ion detection. Fluorescent nanosized GO sheets are micropatterned, and specific aptamers targeting Ag(+) and Hg(2+) are immobilized on the GO array. Upon capture of the target heavy metal ions, electron transfer occurs between th…
The measured redox potential of an actinide at an electrode surface involves the transfer of a single electron from the electrode surface on to the actinide center. Before electron transfer takes place, the complexing ligands and molecules of solvation need to become structurally arranged such that the electron transf…
BACKGROUND: Storage of secondary metabolites with a putative defensive role occurs in the so-called mantle dermal formations (MDFs) that are located in the more exposed parts of the body of most and very likely all members of an entire family of marine mollusks, the chromodorid nudibranchs (Gastropoda: Opisthobranchia…
Abstract A DBD method has been developed to decompose sulphur hexafluoride (SF6) nearly 100% under conditions close to the exhaust gas in industries with energy efficiency of 0.015–0.15 GJ/ton carbon dioxide (CO2) equivalent, 1–2 orders of magnitude higher than CO2 capture and sequestration from power generation boile…
Industrial demands have generated a growing need to synthesize pure metal and metal-oxide nanoparticles of a desired size.We report a novel and convenient method for the synthesis of spherical, size tunable, well dispersed, stable nickel and nickel oxide nanoparticles by reduction of nickel nitrate at room temperature…
To construct a hybrid titania photoanode containing nanoparticles and nanorods of varied size in a multilayer (ML) configuration for dye-sensitized solar cells, the essence of our ML design is a bilayer system with additional layers of nanorods of well-controlled size inserted between the transparent and the scatterin…
Annihilation of dark matter can result in the production of stable Standard Model particles including electrons and positrons that, in the presence of magnetic fields, lose energy via synchrotron radiation, observable as radio emission. Galaxy clusters are excellent targets to search for or to constrain the rate of da…
The propagation of an adhesive crack through an anisotropic heterogeneous interface is considered. Tuning the local toughness distribution function and spatial correlation is numerically shown to induce a transition between weak to strong pinning conditions. While the macroscopic effective toughness is given by the me…
The hexagonal nanomembranes of the group III-nitrides are a subject of interest due to their novel technological applications. In this paper, we investigate the strain- and electric field-induced modulation of their band gaps in the framework of density functional theory. For AlN, the field-dependent modulation of the…
Abstract The controlled growth of self‐assembled second‐phase nanostructures has been shown to be an essential tool for enhancing properties of several composite oxide thin film systems. Here, the role of Y2O3 nanoparticles on the growth of BaZrO3 (BZO) nanorods is investigated in order to understand the mechanisms go…
Heterogeneous reactions on mineral aerosols remain an important subject in atmospheric chemistry because of their role in altering the properties of particles and the budget of trace gases. Yet, the role of coadsorption of trace gases onto mineral aerosols and potential synergistic effects are largely uncertain, espec…
Abstract Collagen biomineralization is a complex process and the controlling factors at the molecular level are still not well understood. A particularly high level of spatial control over collagen mineralization is evident in the anchorage of teeth to the jawbone by the periodontal ligament. Here, unmineralized ligam…
Abstract In the field of polymer solar cells, improving photovoltaic performance has been the main driver over the past decade. To achieve high power conversion efficiencies, a plethora of new photoactive donor polymers and fullerene derivatives have been developed and blended together in bulk heterojunction active la…
ABSTRACT Microgels are crosslinked soft particles with a three‐dimensional network structure that are swollen in a good solvent. They have frequently been termed “smart materials” since the size, softness, and interaction forces between particles are tunable by external stimuli such as temperature, pH, or magnetic and…
The target of the present work is to review the literature regarding the effects of biodiesel blends on nitrogen oxide (NOx) emissions during the transient operation of diesel engines (acceleration, load increase, starting, driving cycles). The most important mechanisms are analyzed on the basis of the fundamental asp…
Traumatic brain injury (TBI) is a major public health problem with no effective clinical treatment. Use of bioactive scaffold materials has been shown to be a promising strategy for tissue regeneration and repair in a number of injury models. Of these scaffold materials, urinary bladder matrix (UBM) derived from porci…
Electron beam-induced deposition (EBID) enables the direct-write patterning of metallic structures with sub-10 nm lateral resolution without the use of resist films or etching/lift-off steps but generally leads to material of poor quality and suffers from a low throughput. These shortcomings were mitigated in recent w…
The influence of residue quality on soil organic C (SOC) retention has been called into question. A field experiment in Northeast Thailand, in which contrasting quality organic residues were applied yearly for 13 yr, was used to determine quantities, locations, and stability of SOC in the soil matrix and identify resi…
