Our efforts to build devices that integrate and interact intimately with biology have led to concepts such as “biofabrication” and “4D printing,” exhibiting the desire to mimic nature and indeed incorporate natural products into structures that provide enhanced function, especially in their ability to interact with, s…
Abstract Supported monometallic Fe/SiO2 and bimetallic Fe–Cu/SiO2 catalysts were synthesized by incipient wetness impregnation. The synthesized catalytic systems were studied in selective hydrogenation of phenyl-acetylene with molecular hydrogen under mild reaction conditions (H2 pressure 1.3 MPa, 80–110°C). The catal…
Abstract The adsorption properties of SO2 molecule on the surface of pyridinic nitrogen doped graphene (4NG), M/4NG and M/2NG (M = Al, Li, Si) are investigated using density functional theory. The adsorption energies have been calculated for the most stable configurations of the molecule on the surface of 4NG, M/4NG,…
Abstract The combination of plasticity theory and continuum damage mechanics facilitates the description of hardening and softening material behavior, accumulation of inelastic strains, and stiffness degradation due to damage. For regularizing softening material behavior in finite element simulations, the enrichment o…
The relativistic generalization of the linearized drift kinetic equation solver NEO-2 is presented which is used for computation of neoclassical transport coefficients and the generalized Spitzer function in 3D toroidal fusion devices (tokamaks and stellarators). This upgrade allows computations of the Spitzer functio…
Abstract A conducting nanocomposite film of 60 nm nano-SnO 2 -polyaniline (PANI) and polyvinyl alcohol (PVA) has been synthesized and analyzed in terms of AC conductivity and dielectric behavior. The conducting polymer nanocomposite of PANI/60 nm (SnO 2 ) and polyvinyl alcohol (PVA) has been prepared via in situ polym…
Abstract Ultrasonic studies of compounds of dihydropyridine series in polar and non-polar solvents at various concentrations and temperatures 303–318 K. Density and ultrasonic velocity and different thermo-acoustical parameters measured. Rao’s constant, molar volume, Wada’s constant, isothermal compressibility reporte…
Abstract The nature of theAI‐*‐AI andAI‐*‐BI interactions inBI‐*‐AI‐*‐AI‐*‐BI of I4σ(4c–6e) in the tellurolane system, C4H8(I)Te–I···I–I···I–Te(I)C4H8(1), and the models is elucidated with QTAIM dual functional analysis (QTAIM‐DFA). Asterisks (*) are employed to emphasize the existence of bond critical points (BCPs) o…
Recently, a non-enzymatic glucose sensor has gained a lot attention, because it is re-useable, fast and simple, as opposed to traditional enzymatic glucose sensor. In this work, two types of electrodes, including electroplated Ni film and Ni foam, were used as sensing electrodes for a non-enzymatic glucose sensor. The…
We report on the modification of the structure and morphology of Bi nanowires of two different diameters (80 or 130 nm) exposed to beams of 400 keV and 1 MeV Au+ until complete wire degradation. For fluences up to ∼1 ion/nm2, the main effect was a slight roughening of the originally smooth surface and the appearance o…
In this paper, the structural properties of porous silicon layer PSL were reported. Photo-assisted (laser) electrochemical etching PECE technique used to fabrication PSL from n-type wafer silicon as a function of etching time. Optical microscopy OM image is confirmed that the surface topography of porous silicon layer…
N₂. The bulk, shear, Young moduli, Poisson ratio, and elastic anisotropy were determined for the polycrystalline Cu(en)(H₂O)₂SO₄ by employing the Hill averaging of the single crystal elastic constants. They were compared to the respective quantities for other low-dimensional magnetic systems. The Cu(en)(H₂O)₂SO₄ compo…
Results from four different approximations to the phonon-assisted quantum adsorption rate for cold atoms on a 2D material are compared and contrasted: (1) a loop expansion (LE) based on the atom-phonon coupling, (2) non-crossing approximation (NCA), (3) independent boson model approximation (IBMA), and (4) a leading-o…
In semiconductor manufacturing, fabrication processes and their materials should be properly co-optimized to achieve required processing results. Unfortunately, it is a very time-consuming procedure, because the number of possible combinations of process/material candidates is very large. Here, we develop a methodolog…

We have successfully prepared Fe3O4/MWCNT nanohybrid with a very simple and economical method. Multi-Walled Carbon NanoTubes (MWCNT) encapsulated with Fe3O4 nanoparticles were synthesized via pyrolyzing of ferrocene. The sample was characterized with XRD, TEM and Vibrating Sample Magnetometer (VSM). Also, Permeability…
The paper, presents the design and analysis of micro piezoresistive pressure sensors using Si, SOI & CNT (Carbon Nanotube) for harsh environment. The sensors were analyzed for the important parameters like sensitivity and temperature sensitivity. Pressure range of 0 to 1MPa, over which the sensors behave linear is con…
In this paper, two kinds of broadband miniaturized bandpass frequency selective surfaces (FSSs) based on fractal transmissive metasurface elements at X band are proposed. FSSs satisfy butterworth response type and stack structures are used to expand bandwidth. FSSs are designed based on the concept of antenna-filter-a…
In this paper, a flexible ultrathin metamaterial absorber has been presented in X-band frequency range. Teflon substrate has been used as a dielectric, hence the proposed absorber offers flexibility and elastic nature. Simulated single-band absorptivity of 99.7% has been achieved at 10.28 GHz frequency with 188 MHz ha…
