Over the past decades, numerous efforts have been devoted to synthesizing nanostructured materials with specific morphology because their size and shape play an important role in determining their functions. Self-assembly using weak and reversible interactions or bonds has provided synthetic routes toward various nano…
Vertical stacking of two-dimensional (2D) crystals has recently attracted substantial interest due to unique properties and potential applications they can introduce. However, little is known about their microstructure because fabrication of the 2D heterostructures on a rigid substrate limits one's ability to directly…
Stimuli‐responsive materials based on interpenetrating liquid crystal‐hydrogel polymer networks are fabricated. These materials consist of a cholesteric liquid crystalline network that reflects color and an interwoven poly(acrylic acid) network that provides a humidity and pH response. The volume change in the cross‐l…
Making a metal contact to the two-dimensional semiconductor ${\mathrm{MoS}}_{2}$ without creating a Schottky barrier is a challenge. Using density functional calculations we show that, although the Schottky barrier for electrons obeys the Schottky-Mott rule for high work function $(\ensuremath{\gtrsim}4.7$ eV) metals,…
The purpose of this review is to provide an overview of current packaging systems, e.g. active packaging and intelligent packaging, for various foods. Active packaging, such as modified atmosphere packaging (MAP), extends the shelf life of fresh produce, provides a high-quality product, reduces economic losses, includ…
Glycerol is an important byproduct of biodiesel production, and it is produced in significant amounts by transesterification of triglycerides with methanol. Due to the highly functionalized nature of glycerol, it is an important biochemical that can be utilized as a platform chemical for the production of high-added-v…
A general method, based on susceptibility tensors, is proposed for the synthesis of metasurfaces transforming arbitrary incident waves into arbitrary reflected and transmitted waves. The proposed method exhibits two advantages: 1) it is inherently vectorial, and therefore better suited for full vectorial (beyond parax…
Nanoscale ferroelectrics are expected to exhibit various exotic domain configurations, such as the full flux-closure pattern that is well known in ferromagnetic materials. Here we observe not only the atomic morphology of the flux-closure quadrant but also a periodic array of flux closures in ferroelectric PbTiO3 film…
We report on the self-assembled growth of 8–10 nm ZnS nanoparticles and subsequently nanowires of size ~100 nm onto DNA templates driven by the electrostatic interaction between mobile cations (Zn2+) and the negative charges of the phosphate group in DNA backbone. The nanowires show free excitonic ultra-violet (UV) em…
Most synchrotron radiation X-ray diffraction (XRD) beamlines have been primarily designed for studying conventional materials, whereas a modern approach to nanomaterials requires a complete control of the diffracted signal, and therefore of the optics and general setup of the beamline. This requirement is especially r…
Molecular properties of N-[(2-hydroxy-3-trimethylammonium)propyl]chitosan (modified chitosan) series with the averaged quaternization degree 90% have been studied in comparison with the unmodified chitosan series by the method of translation isothermal diffusion, viscometry and static light scattering in dilute soluti…
ABSTRACT A series of polyurethane (PU) green composites have been synthesized with varying amounts, namely 0, 2, 4, 8, and 12 wt% of soya protein isolate (SPI) by two methods. In the first method, castor oil (CO) and toluene‐2,4‐diisocyanate (TDI) molar ratio is CO/TDI : 1/1 with varying amounts of the SPI content. In…
Inorganic-organic hybrid crystals were successfully obtained as single crystals by using polyoxotungstate anion and cationic dodecylpyridazinium (C12pda) and dodecylpyridinium (C12py) surfactants. The decatungstate (W10) anion was used as the inorganic component, and the crystal structures were compared. In the crysta…

B-H loop and its modeling are essential for ferromagnetic material characterization and electromagnetic simulation. The objective of this study was to characterize material change by analyzing the corresponding B-H loops and construct a general B-H model for electromagnetic simulation. A B-H loop was decomposed in ter…
Nanotechnology is a rapidly growing field with silver nanoparticles (AgNP) in particular utilized in a wide variety of consumer products. This has presented a number of concerns relating to exposure and the associated toxicity to humans and the environment. As inhalation is the most common exposure route, this study i…
Semiconducting oxides have attracted much attention due to their great stability in air or water and the abundance of oxygen. Recent success in synthesizing a metastable phase of CuGaO 2 with direct narrow band gap opens up new applications of semiconducting oxides as absorber layer for photovoltaics. Using first-prin…
The effects of additions of P and Ag, as well as the de-embrittling elements of copper—B, Mg, Ca, Ti and Zr—in concentrations of 0.085–0.5 wt-% to give some variations in contents within and outside of the DHP specification limits on grain size structure have been investigated under TP-1 casting conditions. Columnar t…
Abstract This work was undertaken to examine the effect of poly(2-acryloyloxyethyl trimethyl ammonium chloride) (PATAC) branches grafted onto the backbones of starch on the toughening of starch film. A series of starch- g -PATAC samples having different levels of grafting ratio were prepared by the graft copolymerizat…
Kitchen workers sustain one of the highest rates of occupational burn injuries through exposure to the various thermal hazards present in institutional and restaurant kitchens. The jacket of the chefs’ uniform has the potential to act as a protective garment, although the extent of the protection afforded by this clot…
