Abstract Food quality and safety are major concerns in the food industry. Antimicrobial packaging can be considered an emerging technology that could have a significant impact on life and food safety. Antimicrobial agents in food packaging can control the microbial population and target specific microorganisms to prov…
Abstract The durability of a commercially available injection molding grade polylactide (PLA) was assessed by exposure to conditions of elevated temperature and humidity over a period of several weeks. Moisture absorption, molecular weight, and mechanical performance were monitored over time and as a function of cryst…
Abstract Three composites based on cyanate (CE) resin, aluminum nitride (AlN), surface‐treated aluminum nitride [AlN(KH560)], and silicon dioxide (SiO 2 ) for microelectronic packaging, coded as AlN/CE, AlN(KH560)‐SiO 2 (KH560)/CE, and AlN‐SiO 2 /CE composite, respectively, were developed for the first time. The therm…
Abstract The effect of silane treatment on the water absorption properties of bamboo matting reinforced epoxy composites were investigated. Experiments using γ‐aminopropyltriethoxy silane, 3‐trimethoxysilylpropylmethacrylate, vinyltris(2‐methoxyethoxy)silane, bis[3‐(triethoxysilyl)propyl]tetrasulfide, 3‐aminopropyltri…
We report on measurements of Seebeck effect in single-crystal VO(2) microbeams across their metal-insulator phase transition. One-dimensionally aligned metal-insulator domain walls were reversibly created and eliminated along single VO(2) beams by varying temperature, which allows for accurate extraction of the net co…
We here investigate the emission properties of rare-earth-doped oxide nanoparticles with the aim to understand the commonly observed altered properties of nanoparticles as compared to the bulk counterparts. This is usually attributed to the detrimental effect of surface states that quench the excited states involved i…
Abstract In this article, biodegradable poly(butylene succinate‐ co ‐butylene terephthalate) (PBST) copolyesters with high molecular weights were synthesized by direct esterification and polycondensation route. The reaction conditions and catalytic systems were investigated in detail. Through balancing the reaction ef…
The purpose of this study was to use a convenient synthetic strategy to prepare a new family of biodegradable amino acid-based poly(ester amide)s (PEAs) with pendant amine groups along the polymer backbone, and investigate the applications of the new polymers in the biomedical area. Two amino acids, L-phenylalanine (P…
We have characterized electron transfer from photoexcited CdS quantum dots (QDs) to TiO 2 nanoparticles (NPs) through bifunctional phenylene-containing linkers ( L ). Three L were examined: 4-mercaptobenzoic acid (4MBA), 2-mercaptobenzoic acid (2MBA), and 4-mercaptophenylacetic acid (4MPAA). Only 4MBA and 4MPAA promot…
Abstract The conducting polymer composite material is desired to have a high dielectric constant and high dissipation factor in low and high frequency ranges, so that it can be used in charge storing devices, decoupling capacitors, and electromagnetic interference (EMI) shielding applications. Currently, on‐going rese…
DWS-based tracer particle microrheology is demonstrated to be a useful way to study the dynamics of aqueous Pluronic L64 solutions, which is viewed as a model adhesive hard sphere (AHS) system. The short-time dynamics of aqueous Pluronic L64 solutions indicate a purely hydrodynamic high frequency microviscosity as pre…
The effects of substituting nonmagnetic Mg 2+ and Zn 2+ ions for the Mn 2+ ( S = 5/2) ions on the structural, magnetic, and dielectric properties of the multiferroic frustrated antiferromagnet MnWO 4 were investigated. Polycrystalline samples of Mn 1− x Mg x WO 4 and Mn 1− x Zn x WO 4 (0 ≤ x ≤ 0.3) solid solutions wer…
In this paper, we reported the synthesis of nearly monodisperse and well-defined one-dimensional (1D) rare earth fluoride (β-NaREF 4 ) (RE = Y, Sm, Eu, Gd, Tb, Dy, and Ho) nanowires/nanorods by in situ acid corrosion and an ion exchange approach using RE(OH) 3 as precursors via a facile hydrothermal route. X-ray diffr…
An extensive study on morphological parameters of ceramic sponge structures of different material, porosity, and pores per linear inch (ppi) number was performed. Volume image analyses of magnetic resonance imaging (MRI) and X-ray tomography (CT) measurements were carried out to determine experimentally the geometric…
Ultrathin palladium hexagonal nanosheets were synthesized in emulsions constituted of droplets of toluene containing Pd complexes in water and stabilized by CTAB as surfactant and in quaternary mesophases formed by water, toluene containing Pd complexes, CTAB, and a cosurfactant. We have identified slow reduction and…
We study the energy spectra and wave functions of graphene rings formed from metallic armchair ribbons, near zero energy, to search for properties which may be identified with ``effective broken time-reversal symmetry'' (EBTRS). Appropriately chosen corner junctions are shown to impose phase shifts in the wave functio…
The carbon nanotube (CNT) industry is expanding rapidly, yet little is known about the potential environmental impacts of CNT manufacture. Here, we evaluate the effluent composition of a representative multiwalled CNT synthesis by catalytic chemical vapor deposition (CVD) in order to provide data needed to design stra…
The atomic and electronic structures of the black phosphorus surface are investigated by means of scanning tunneling microscopy (STM) combined with density functional theory (DFT) calculations for the first time. STM measurements reveal that the atoms on the surface occupy almost the same sites that they would have in…
We present a simple two-step method to fabricate dual-scale superhydrophobic surfaces by using replica molding of poly(dimethylsiloxane) (PDMS) micropillars, followed by deposition of a thin, hard coating layer of a SiO(x)-incorporated diamond-like carbon (DLC). The resulting surface consists of microscale PDMS pillar…
Cutinases are responsible for hydrolysis of the protective cutin lipid polyester matrix in plants and thus have been exploited for hydrolysis of small molecule esters and polyesters. Here we explore the reactivity, stability, and structure of Aspergillus oryzae cutinase and compare it to the well-studied enzyme from F…
