In this paper, we investigate the effect of Dy and Pr substitution for Nd on the microstructure and the magnetic properties of Nd-Fe-B alloys fabricated by using the strip-casting process. The addition of Dy and Pr changes the melting temperature of the strips, which results in differences in undercooling during solid…
We report graphene oxide (GO) preparation from graphite powder through two different and improved versions of Hummers method. For the first method, we replicated the work already reported by T. Wu et al. In the second method, we followed the same procedure but with stirring intervals in between consecutive process ste…
Organic light emitting diodes (OLEDs) with nanoscale corrugation for light extraction (NCLE) enhanced the current efficiency and power efficiency. The haze of the nanoscale corrugation for light extraction is comparable to that of bare glass. Furthermore, the OLEDs with NCLE exhibited angle‐stable electroluminescence…
The neutron diffraction and measurements of specific heat and magnetization were carried out on single crystals of a quantum spin ice system Yb 2 Ti 2 O 7. The thermal hysteresis loops of temperature dependence of the magnetization and neutron diffraction intensity indicate a first-order ferromagnetic transition, wher…
Physical and optical interactions between metal films and organic semiconductors underpin the functionality of many organic optoelectronic devices. As shown on page 3302 by Z. Shen and D. M. O'Carroll, disordered nanoporous silver thin films fabricated by thermally-assisted dewetting are used to influence the morpholo…
The temperature dependence of diffraction efficiency and response time in two holographic systems using doped liquid crystals (LC) is investigated. For dye‐doped LCs, the response time is generally robust to temperature variation but the diffraction efficiency is temperature‐sensitive; whereas, the QD‐doped LC remains…
In this study the catalytic dehydrogenation of ethylbenzene to styrene was investigated in a simulated tubular sodalite membrane reactor. The high quality microporous sodalite membrane was synthesized by direct hydrothermal method and characterized by single gas permeation measurements. The performance of the prepared…
We have developed highly reliable oxide TFT arrays by allprinted maskless process from gate to passivation layers with 100 ppi RGB resolution. The threshold voltage shifts under positive and negative bias‐temperature‐stress at 50 °C after 10 5 seconds were less than 0.8 and 0.3 V, respectively.
Austenitic stainless steels are extensively used in various applications requiring good corrosion resistance and formability. In the current study, the formation of nano/ ultrafine grained austenitic microstructure in a microalloyed AISI 304L stainless steel was investigated by the advanced thermomechanical process of…
Purpose: The mitochondrion, like the cell nucleus, contains genetic material and plays several critical roles that determine the cell viability, including neutralization of free radicals within the cell. Studies have shown that irradiated cells with impaired mitochondria will incur more damage to the cell nucleus. Thi…
Purpose: To accurately model different breast geometries using a tissue equivalent phantom, and to classify these tissues in a coherent x‐ray scatter imaging system. Methods: A breast phantom has been designed to assess the capability of coded aperture coherent x‐ray scatter imaging system to classify different types…
We study p-polarized nonlinear surface polaritons (NLSP) propagating along the interface of an epsilon-near-zero metamaterial with saturable nonlinearity, very small negative linear permittivity and an optically linear medium. On the basis of the exact solution of Maxwell's equations, we investigate the relationship b…
Abstract The self‐assembly of MnII ions and 1,4‐bis(2‐methyl‐imidazole‐1‐yl)benzene (bip) with two different dicarboxylate ligands, benzophenone‐4,4′‐dicarboxylic acid (H2bda) and 1,4‐naphthalenedicarboxylic acid (H2nda) via hydrothermal synthesis resulted in two interesting coordination polymers, [Mn(bda)(bip)]n (1)…
Isothermal melt crystallization kinetics of PVDF was investigated by differential scanning calorimetry. Thin PVDF film has been fabricated by the solvent casting technique using dimethylformamide (DMF). Then, the samples were melted and subsequently crystallized in the range of the crystallization temperature (Tc) bet…
Nanostructured zinc sulfide ( ZnS ) thin films were synthesized in polyvinyl alcohol matrix by chemical bath deposition and self-assembly techniques. ZnS nanostructured thin films show second harmonic generation (SHG) under irradiation with a pico-second Nd :YAG laser system and the second harmonic intensity is higher…
The goal of this study is to investigate the energy transfer in metals due to electron–phonon (lattice) interaction using the two-temperature model (TTM). In TTM, molecular dynamics simulation and classical energy equation are used to find the lattice and electronic temperatures, respectively. An initial temperature p…
Abstract Geopolymers are polymeric materials resulting from the polycondensation reaction of alumino-silicate materials in a strongly alkaline environment. In consequence, stable polymeric networks of aluminosilicates are formed. The binding potential of FA (fly ash) amorphous component can also be “activated” by mech…
We present detailed theoretical studies of the H-bonded complexes formed from interaction between 5-fluorouracil and various six-membered cyclic nitrosamine compounds. In this study, an investigation on intermolecular interactions in X-NU (X = CH2, SiH2,BH, AlH, NH, PH, O and S) complexes is carried out using density…
We investigated the effect of the polymerized surfaces on the anchoring energy and pre‐tilt angle of liquid crystal alignment. Ultraviolet light‐illuminated cell initiates polymerization and produces sub‐micron sized polymer protrusions. Experimental evidences reveal the relation between the curing conditions and the…
