Fluorinated epitaxial graphene has potential applications in organic electronics. We present the calculation results by means of first-principles density-functional-theory for various fluorination patterns. Our results indicate that semi-fluorinated graphene conformations follow the same energetic order as the corresp…
Natural fibers used as reinforcement in composite materials present specific mechanical properties, which are comparable to glass fibers. In addition, they have the advantage of being renewable and recyclable. However, their main drawback is their inherent susceptibility to moisture expansion, which has the effect of…
TTF derivatives decorated with four aryls through the sulfur bridges are employed to form the donor–acceptor type inclusion complexes with fullerenes. The key factor for the formation of inclusion complexes is the introduction of structural flexibility in TTF molecules along with the molecular size matching with fulle…
Sources of single photons are of fundamental importance in many applications as to provide quantum states for quantum communication and quantum information processing. Color centers in diamond are prominent candidates to generate and manipulate quantum states of light, even at room temperature. However, the efficiency…
Mechanical and thermal properties of poly(vinyl chloride) (PVC)/nanoclay (NC) composites prepared via melt‐blending in a single‐screw extruder were investigated. The effects of NC type, NC content, and K‐value of PVC were evaluated by using L9 orthogonal array of the Taguchi approach. The most influential variables an…
The phenomena of catalyst deactivation and the effects of regeneration method on the characteristics and activity of Ni/ZA catalyst after being used in a continuous cracking reaction of polypropylene have been studied. Ni/ZA catalyst was prepared using sonochemical method with total metal intake of 4%. Characteristics…
A unique heterostructured optoelectronic material (HOM), consisting of a reduced graphene oxide (RGO) layer with spatially distributed CdS, suspended by zinc oxide (ZnO) nanorods, is presented. The key features of this HOM are the assembly of the components in a manner so as to realize an effective integration between…
Abstract Nanocubes (NCs) were found to be produced by the irradiation of nanosecond UV pulses to an aqueous solution of silver nitrate. The photoproduct was turned to nanospheres (NSs) when irradiated with a certain amount of sodium dodecyl sulfate (SDS). The SDS concentration to alter the photoproduct from NCs to NSs…
Removal of volatile organic compounds (VOC) and indoor air quality regulation through adsorbers required exchange or maintenance of active materials. In this work, we combine well known VOC adsorbers with oxidation catalysts as intimate particulate mixtures. We demonstrate how typical VOC can subsequently adsorb on su…
An investigation was performed into the rheological properties and stability of emulsion explosive matrix with different surfactants. The surfactants were oligomers of the polyisobutylene succinic anhydride (PIBSA) based on different head group and relative low molecular weight sorbitan monooleate (Span 80). The visco…
Although theoretically feasible, synthesis of boron nanostructures is challenging due to the highly reactive nature, high melting and boiling points of boron. We have developed a thermal vapor transfer approach to synthesizing amorphous boron nanowire using a solid boron source. The amorphous nature and chemical compo…
We explore possibilities of waveguide-mode interference lithography (WMIL) technique for high contrast subwavelength structures in the visible region. Selecting an appropriate waveguide-mode, we demonstrate high contrast resist mask patterns for the first time. TM1 mode in the waveguide is shown to be useful for provi…
The interaction between vascular endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) in a complex hemodynamic and mechanical environment plays an important role in the control of blood vessel growth and function. Despite the importance of VSMCs, substitutes are needed for vascular therapies. A potential V…
An analytical full wave model of parallel, randomly centered carbon nanotubes (CNTs) embedded in a dielectric slab was developed to calculate the electromagnetic scattering from CNT composites. The model simulates empty and metal-filled single walled CNTs as infinitesimally thin wires, parallel and infinitely long in…
We report optical gain enhancements in Si nanocrystals (Si-NCs) via hydrogenation and Ce3+ ion doping. Variable stripe length technique was used to obtain gains. At 0.3 W/cm2 pumping power density of pulsed laser, net gains were observed together with gain enhancements after hydrogenation and/or Ce3+ ion doping; gains…
Solid polymer electrolyte (SPEs) has drawn great attention nowadays, particularly in the field of science and applied science, specifically, those used as separators in industries and researchers for the assemblage of some “classified batteries” and super capacitors. In this report, we present the grandeur of this SPE…
Thin films of lanthanum phosphate (LaPO4) are produced by atomic layer deposition (ALD) for the first time, using a precursor combination of (CH3)3PO4, La(thd)3 (Hthd = 2,2,6,6‐tetramethylhepta‐3,5‐dione), H2O, and O3. The deposition process is studied via an in‐situ quartz crystal microbalance (QCM) and found to be a…
[6] n Cyclacenes and short zigzag [6] n carbon nanotubes ( n = 5–10) have unstable singlet open‐shell (S os ) ground states. We have boosted their stability by implementing altering Ge―C bonds that acquire S cs ground states with larger band gap (Δ E LUMO–HOMO ) at B3LYP and BPW91 levels of theory. Fascinatingly, homo…
We present the design, fabrication, and physical interpretation of an infrared dual-band metamaterial absorber. The unit cell of the metamaterial absorber consists of a cross resonator ringed by four split-ring resonators spaced a distance above a gold ground plane with a dielectric layer of SiO2. The absorber shows t…
Random and <001> textured potassium sodium niobate – [ K,Na ] NbO 3 ( KNN ) ceramics with 1 mole% CuO sintering aid were fabricated in ribbon form through a combination of novel alginate gelation process and templated grain growth methods using platelike sodium niobate ‐ NaNbO 3 ( NN ) template particles. The platelik…
