Luminescent solar concentrators (LSCs) are low cost photovoltaic devices, which reduce the amount of necessary semiconductor material per unit area of a photovoltaic solar energy converter by means of concentration. The device is comprised of a thin plastic plate in which luminescent species (fluorophores) have been i…
Hybrid films incorporating high dielectric constant k ceramics (BaTiO3 and TiO2) in deoxyribonucleic acid (DNA) were fabricated from highly stable dispersions of the ceramic nanoparticles in viscous, aqueous DNA solutions. Dielectric and electrical properties of the as-prepared nanocomposite films were investigated fo…
Analysis data detailing the microstructure of fluorine-implanted γ-TiAl alloys are presented. Correlations are done among the shape of the F implant profiles, the F dose, and the quality of the resulting oxide scale after high-temperature exposure to air. It is shown that good oxidation protection is associated with G…
A novel cold reactor apparatus for in situ gasification chemical looping combustion (iG-CLC) is proposed and investigated. It is mainly comprised of a circulating fluidized bed (CFB) riser as the fuel reactor and a cross-flow moving bed as the air reactor. The direct hydraulic link between the two reactors brings inhe…
As the technology node keeps shrinking down to sub-28 nm, mask topography (Mask3D) effect is one of the most influential factors to draw intensive research lately. To build a successful Mask3D compact model, the runtime efficiency, accuracy and the flexibility to handle various geometry patterns are the three most imp…
Strontium titanate, SrxTiyOz (STO), thin films with various cation stoichiometries were deposited by plasma‐assisted atomic layer deposition (ALD) using cyclopentadienyl‐based metal precursors and oxygen plasma as counter‐reactant. [Sr]/([Sr] + [Ti]) compositions ranging from 0.46 to 0.57 were obtained by changing the…
Elastic composite of wrinkled graphene sheets and Si nanoparticles has been prepared through engineering charged Si nanoparticles capping with 3-aminopropyl triethoxysilane and graphene oxide in colloidal state. In the composite, the Si nanoparticles are uniformly wrapped by the graphene sheets. When used as an anode…
Multilevel memory capability of self-assembled indium-zinc-oxide (IZO) electric-double-layer (EDL) thin-film transistors gated by nanogranular SiO2 proton conducting electrolytes is investigated. More than four distinct memory states are obtained by programming gate voltage. The observed multilevel storage behavior is…
Inefficient gene delivery poses a challenge for non‑viral gene therapy. Cytoplasmic and nuclear membrane barriers are responsible for the inefficiency as they restrict the import of exogenous genes. The present study aimed to improve the transfection efficiency using a novel gene delivery system, which consisted of tw…
We demonstrate gate-controlled spin-orbit interaction (SOI) in InAs high-electron mobility transistor (HEMT) structures transferred epitaxially onto Si substrates. Successful epitaxial transfer of the multilayered structure after separation from an original substrate ensures that the InAs HEMT maintains a robust bondi…
We present here polymorphs and solvates of two isomeric bis -phenols namely 4-[(2-fluorophenyl)(4-hydroxy-3,5-dimethyl phenyl)methyl]-2,6 dimethylphenol ( bis -phenol 1 ) and 2-[(2-fluorophenyl)(2-hydroxy-3,5-dimethylphenyl)methyl]-4, 6 dimethylphenol ( bis -phenol 2 ), and some of their interconversions. Two polymorp…
We performed micromagnetic numerical and analytical calculations in studying the effects of change in the primitive unit cells of one-dimensional (1D) vortex arrays on collective vortex-gyration dispersion. As the primitive basis, we consider alternating constituent materials (NiMnSb vs. Permalloy) and alternating dim…
With more HVDC transmission lines being built in China, the situation of the plastic greenhouses existing underneath the HVDC lines is becoming more common when the transmission lines pass over the farmland. The ionic space charges generated by corona discharge of HVDC transmission lines strengthen the electric field…
In this work, wear behavior and microstructural characterization of porous layers produced in glass-ceramic substrates by pulsed laser irradiation in the nanosecond range are studied under unidirectional sliding conditions against AISI316 and corundum counterbodies. Depending on the optical configuration of the laser…
The heats of formation (HOFs), energetic properties, strain energies, thermal stability, and impact sensitivity for a series of trinitromethyl- or dinitromethyl-modified CL-20 derivatives were studied by using density functional theory. It is found that the trinitromethyl group is an effective structural unit for impr…
A sputtering process using multi-stacking of carbon and metal thin films with subsequent annealing process to reactively form metal carbides (TiC, TaC, and W2C) has been presented. Grain sizes of the carbides are as small as 3.9, 3.2, and 1.9 nm for TiC, TaC, and W2C, respectively. Work functions of TiC, TaC, and W2C…
A series of monochelic polybutadienes with a ureidopyrimidone terminal group (MPBd-UPy) has been synthesized using anionic polymerization and chain-end transformation. Monochelic polybutadiene with two UPy terminal groups, MPBd-(UPy)2, has also been synthesized to study the effect of chain-end concentration on hydroge…

BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers worldwide. The majority (approximately 60%) of patients with CRC will eventually develop liver metastases, which remain the most common cause of mortality in these patients. This study aimed to evaluate the therapeutic effect and tolerability of gel…
Abstract The removal of sulfur species from the biomass‐derived producer gas after gasification is required to protect downstream catalysts. Finding suitable materials for high‐temperature desulfurization is one of the main challenges for the improvement in the efficiency of catalytic biomass conversion. The biomass‐d…
