Multiwalled carbon nanotubes (MWCNTs) were covalently modified with different molecular weights 400 and 2000 poly(oxyalkylene)-amine bearing DGEBA epoxy (POA400-DGEBA and POA2000-DGEBA) oligomers via a grafting method. The weight-average molecular weights of POA400-DGEBA and POA2000-DGEBA were measured as 1623 and 9231 with polydispersity indices (PDIs) of 2.3 and 1.6, respectively. The oxidize...

Aims: to investigate the potential of Mucuna milk influence weight gain, blood lipid levels and redox status in a rat model on high-fat diet.
 Study Design: 42 healthy male Wistar rats were randomly divided into 7 groups 6 rats. Group I received standard diet; II was fed high fat diet only; III treated with Atorvastatin (10 mg/kg per day) orally for 4 weeks; IV, V, VI VII tests given 20 mL...

We examine ceramic tape-casting and anode electrolyte co-firing for large-scale manufacturing of protonic fuel cells. confirm the reactivity Ni, a commonly used anode, with BaZr0.8M0.2O3?? (BZM20: M = Sc, In, Lu, Yb, Y or Gd). Addition 0.4 mol% NiO to BZM20 at 1778 K, produces BaM2NiO5 Gd. No reaction occurs Lu Yb. The proton conductivity all BZM20s decreases by approximately 30% because doping...

We study the thermoelectric properties of bulk $MoSe_2$ within relaxation time approximation including electron-phonon and ionized impurity interactions using first-principles calculations at room temperatures. The anisotropy this two-dimensional layered metal dichalcogenide is studied by electron mobility in cross-plane in-plane directions. show that two orders magnitude smaller than one. incl...

We numerically solved the full-dimensional electronic time-dependent Schrödinger equation for H2+ with Born-Oppenheimer approximation under different sin2-shaped and trapezoidal laser pulses at some wavelengths, I = 1 × 1013, 3 1013 6 Wcm−2 intensity 4.73 a.u. 7.0 internuclear distances. Some structures such as minima oscillatory patterns appearing in high-order harmonic generation (HHG) spectr...

The hierarchical linear mixed (HLM) estimation method is process multilevel data analysis.Main Finding: funding show that ...

Systemy produkcyjne stanowią jeden z głównych filarów przedsiębiorstw. Ich wydajność i zasady funkcjonowania determinują finalną jakość produktów, których odbiorcami są instytucje oraz konsumenci końcowi. Jednak współcześnie oprócz wcześniej wymienionych zagadnień pojawiły się nowe wymagania związane koncepcją zrównoważonego rozwoju. Metody produkcji, wpływ na środowisko naturalne czy poszanowa...

Abstract RF-driven negative hydrogen ion sources are typically operated at low frequencies around 1 MHz, gas pressures or below Pa and large power densities up to 10 Wcm -3 . Owing these conditions as well the current discharge geometries antenna layouts, RF coupling is far from optimized, i.e. only a fraction η of delivered by generator absorbed plasma. This considerably limits performance rel...

Background & Aim: Effects of ultra violet spectrum on plants due to their obligatory requirement for sunlight for survival are unavoidable. Direct effects of UV on plant growth and development are generally negative and usually they use many different defense mechanisms to acclimate and protect themselves. Material & Methods: The present research for the first time was conducted to investigate...
