The main challenge in the oxygen delignification process is the improvement of selectivity. To further understand the effect of the amount of hydroxyl radicals on the selectivity of oxygen delignification, in this work, the hydroxyl radicals were generated by the improved Fenton reaction system and were quantified by…
Directed self-assembly (DSA) and nanoimprint lithography (NIL) have been widely developed for low-cost nanoscale patterning. Although they are currently regarded as "alternative lithography," some papers show their potential to be candidates for next-generation lithography (NGL). To actualize the potential, the contri…
Different approaches have been adopted for assessing the potential risks of conventional chemicals and products for human health. In general, the traditional paradigm is a toxicological-driven chemical-by-chemical approach, focusing on single toxic endpoints. Scope and responsibilities for the development and implemen…
Semiconductor nanowires have been intensively investigated in order to study their unique fundamental and application properties that develop at the nano-scale. One of main problems in the growth of III-V semiconductor nanowire is uniformity both of in dimension and composition of chemical elements. We synthesized InG…
This study proposes a seed/template-free method that affords high-purity semiconducting nanowires from nanoclusters, which act as basic building blocks for nanomaterials, under supercritical CO2 fluid. Polycrystalline nanowires of Gd-doped ceria (Gd-CeO2) were formed by CO2-mediated non-oriented attachment of the nano…
We predict a tunable and nonadiabatic Berry phase effect of Dirac fermions, which is an electronic analog of the Pancharatnam phase of polarized light. The Berry phase occurs as a scattering phase shift in a single scattering event of transmission or reflection of Dirac fermions at a junction with a spatially nonunifo…
Diferentes mezclas de alcohol polivinílico (PVA)-almidón-sorbitol fueron preparadas por un proceso de casting. La proporción de PVA y almidón empleada para preparar las mezclas fueron las siguientes: PVAA-1 (10 % PVA-90 % almidón), PVAA-2 (25 % PVA-75 % almidón), PVAA-3 (40 % PVA-60 % almidón) y PVAA-4 (55 % PVA-45 %…
Nanoparticles (NPs) entering the human body are immediately confronted with the innate part of human immune system. In particular, monocyte and neutrophil granulocytes readily clear particles by phagocytosis, even if in the case of NPs the uptake mechanism may be classified as macropinocytosis. Among engineered nanopa…
We used a simple electrospinning technique to fabricate a highly potent silver-organoalkoxysilane antimicrobial composite from AgNO3-polyvinylpyrrolidone (PVP)/3-aminopropyltrimethoxysilane (APTMS)/tetraethoxysilane (TEOS) solution. Spectroscopic and microscopic analyses of the composite showed that the fibers contain…
9, 10-Anthracenedione and 1-hydroxy-4-methylanthraquinone showed antibacterial activity against Staphylococcus aureus, Micrococcus luteus, Bacillus cereus and Escherichia coli. Due to the synergistic effect of the individual compounds, the crude extract from leaves and roots of Ceratotheca triloba exhibited good poten…
We investigated the proton irradiation effect of thermal conductivities for individual single-crystalline Bi nanowires grown by the on-film formation of nanowires (ON–OFF). The thermal conductivities of Bi nanowires with diameter of 154 and 112 nm were measured using suspended devices before and after proton irradiati…
Dielectric properties of poly(acrylic acid)-graft-poly(ethylene oxide) (PAA-g-PEO) aqueous solution were measured as a function of concentration and temperature over a frequency range of 40 Hz to 110 MHz. After subtracting the contribution of electrode polarization, three relaxation processes were observed at about 20…
The effect of low temperature post-annealing on the phase transitions and magnetocaloric properties in bulk Ni44Mn45Sn11 alloy has been investigated. The results indicate that with the increase of annealing temperature, the martensite start temperature decreases rapidly, while the Curie temperature of austenitic phase…
We experimentally investigate segregation behaviors of binary granular mixtures consisting of granular chains and spherical grains with different interstitial media under vertical vibrations. A quantitative criterion is proposed to locate the boundaries between different vibrating phases. The water-immersed granular m…
In this work, the growth and ferromagnetic properties of ε-FeSi thin film on Si(100) substrate prepared by molecular beam epitaxy are reported. The inter-diffusion of Fe layer on Si(100) substrate at 600 °C results in polycrystalline ε-FeSi layer. The determined activation energy was 0.044 eV. The modified magnetism f…
This study was carried out to evaluate the effect of long-term natural aging ongermination ability and several biochemical characteristics regarding soluble sugars and polyphenol matter contents and radical scavenging activity of Periplocaangustifolia Labill. (Asclepiadaceae) stored seeds for 1, 3, 7, 10, 11 and 15-ye…
A method for automatic computation of parameter derivatives of numerically computed light scattering signals is demonstrated. The finite-element based method is validated in a numerical convergence study, and it is applied to investigate the sensitivity of a scatterometric setup with respect to geometrical parameters…
As device design rule has been made pattern size shrink, overlay control has become one of the most critical issues for semiconductor manufacturing. Advanced lithographic exposure tools, such as EUV and i-ArF scanners, require high-order overlay corrections. In conventional overlay metrology, several overlay targets a…
The solubilities in water of four main ginger bioactives, 6-gingerol, 6-shogaol, 8-gingerol and 10-gingerol, were predicted using a conductor-like screening model for real solvent (COSMO-RS) calculations. This study was conducted since no experimental data are available for ginger bioactive solubilities in hot water.…
We investigated the release characteristics of single-wall carbon nanotubes (CNTs) synthesized by a pilot-scale plant. In addition to on-site aerosol measurements at the pilot-scale plant where the CNTs were synthesized, harvested, and packed, we conducted dustiness tests by vortex shaking and by transferring CNTs fro…
