The EUV-photomask is used as mirror and no longer as transmissive device. In order to yield defect-free reticles, repair capability is required for defects in the absorber and for defects in the mirror. Defects can propagate between the EUV mask layers, which makes the detection and the repair complex or impossible if…
This article investigates the effect of pretilt angle on disclination lines of liquid crystal (LC) lenses. When the pretilt angle of LCs is higher than 7°, the disclination lines are reduced and are moved to the boundary of the LC lens. The disclination lines at the boundary do not influence the focused beam profile o…
Jute fabrics/melamine composites (20% fiber) were prepared by compression molding. Mechanical properties of the composites were evaluated. Mechanical properties of starch-treated jute/melamine composites, including tensile strength (31%), bending strength (29%), tensile modulus (23%), bending modulus (25%), impact str…
We report a new strategy in the use of graphene layers as a template for remarkably enhancing the growth of single crystalline one-dimensional (1-D) nanostructures and for selectively controlling the growth area. Single crystalline RuO 2 nanowires of high density were almost exclusively obtained over a large area of g…
With the potential to mimic the human brain, phase-change memories are operating faster, while imaging provides further insight into the switching mechanism.
The required measurement precision for multilayered EUV mask metrology is set below 0.4 nm three sigma. In addition to limited precision of CD-SEM, there are fundamental physical factors that deteriorate the accuracy of the measurements, the most important of which is charging. It is widely believed that EUV masks are…
Abstract Towards the development of copolymeric nanocomposites, N‐3(trifluoromethyl)phenyl‐7‐oxanorbornene‐5,6‐dicarboximide (TFI) monomer and a macromonomer of polyhedral oligomeric silsesquioxane (POSS) were synthesized. Ring‐opening metathesis polymerization to copolymerization of specified proportions of the two c…
We report on differently ordered colloidal phases of a mixture of paramagnetic and diamagnetic colloids subject to a quickly varying time dependent magnetic field. Effectively paramagnetic and effectively diamagnetic colloids are created from paramagnetic and nonmagnetic colloids immersed into a thin film of aqueous f…
We study a Brownian particle on a moving periodic potential. We focus on the statistical properties of the work done by the potential and the heat dissipated by the particle. When the period and the depth of the potential are both large, by using a boundary layer analysis, we calculate a cumulant generating function a…
Lanthanum phosphate (LaPO4) phosphor materials with one-dimensional (1D) nanorods and nanoparticles were successfully synthesised from LaCl3 · 7H2O and Na3PO4 · 12H2O with pH adjusted at the range 1–6 using 37% HNO3 by the microwave radiation at 180 W for 60 min. X-ray diffraction patterns indicated that the as-synthe…
The vibrational properties of Chinese fir (Cunninghamia lanceolata) wood were investigated in this study as a function of changes in moisture content (MC) and grain direction. The dynamic modulus of elasticity (DMOE) and logarithmic decrement (δ) were examined using a cantilever beam vibration testing apparatus. It wa…
Gas phase decarboxylation of hydrolyzed free fatty acid (FFA) from canola oil has been investigated in two fix-bed reactors by changing reaction parameters such as temperatures, FFA feed rates, and H2-to-FFA molar ratios. FFA, which contains mostly C18 as well as a few C16, C20, C22, and C24 FFA, was fed into the boil…
This book examines and documents methods used in safety assessment for radioactive waste disposal facilities, shows collective views based on the methods’ similarities and differences, and to identifies future work.
OPC models describe the entire patterning process, including photomask, optics, resist, and etch as a set of separately characterized modules. It is difficult, however, to definitively calibrate the optics model since the aerial image is not easily measurable. It is therefore common to calibrate relevant optical param…
We the Editor and Publisher of Journal of Experimental Nanoscience retract the following three articles:1. Nazari, Ali, and Shadi Riahi. “The effects of ZnO2 nanoparticles on split tensile strength of self-compacting concrete.” Journal of Experimental Nanoscience 7.5 (2012): 491-512, https://www.tandfonline.com/doi/fu…
We investigated the photothermal excitation of a mechanical resonator consisting of a carbon nanotube cantilever. Higher mode oscillations were successfully measured resulting from the elimination of parasitic vibrations. Based on a simple lumped model for the photothermally excited carbon nanotube cantilever, the the…
Conformational changes are essential for protein-protein and protein-ligand recognition. Here we probed changes in the structure of the protein ubiquitin at low temperatures in supercooled water using NMR spectroscopy. We demonstrate that ubiquitin is well folded down to 263 K, although slight rearrangements in the hy…
PURPOSE: The high breast density is one of the biggest risk factors for breast cancer. Identifying patient having persistent high breast density is important for breast cancer screening and prevention. In this work the authors propose for the first time an x-ray phase-shifts-based method of breast density measurement.…
Abstract Poly(vinyl laurate) (PVL) and poly(vinyl stearate) (PVS) were synthesized by means of cobalt‐mediated radical polymerization (CMRP). Cobalt(II) diacetylacetonate (Co(acac)2) was demonstrated to control the radical polymerization of these monomers in solution. Molecular weights up to 15,000 g·mol−1 were obtain…
The use of matured compost as an inoculation agent to improve the composting of vegetable and fruit wastes in a laboratory-scale composter was evaluated, and the commercial feasibility of this approach in a pilot-scale (1.8 x 10(4) L) composter was subsequently confirmed. The effect of aeration rate on the physico-che…
