Pr-Fe-B/Ta bilayer films were sputtered on glass substrates in a high vacuum magnetron sputtering system. Before sputtering the magnetic Pr-Fe-B thin films, Ta underlayers with two different crystal structures, hexagonal close-packed HCP(0002) and body-centered cubic BCC(110), were prepared at substrate temperatures o…
The addition of mechanical property characterization to textile development can yield next-generation fabrics for new applications. Understanding the characteristics of the materials being integrated with existing fabric matrices is paramount in predicting how targeted enhanced properties will manifest in novel compos…
This work aims at deriving analytical solutions for the molecular architecture of multi‐block polymer synthesized in a dual‐catalyst single CSTR. While the relevant equations are developed for homopolymerization, they can easily be extended to copolymerization. Special emphasis is placed on the quantities associated w…
A compact quenching furnace used under high magnetic fields was developed. The range of the annealing temperature and magnetic field of this apparatus was T ≤ 643 K and μ0H ≤ 15 T. The cooling rate was about 40 K/s in magnetic field of μ0H = 15 T. As a performance test of the furnace, an in-field heat treatment at 643…
In petroleum and petrochemical industries, offshore and onshore systems have to function in an aggressive environment that exposes the production equipment components to thermal cycling and wear and corrosion. Although maintenance of material degradation in oil and gas is costly, internal and external parts of the equ…

We investigated temperature- and fluence-dependent dynamics of the time-resolved optical reflectivity in undoped spin-density-wave (SDW) and doped superconducting (SC) ${\mathrm{EuFe}}_{2}{(\mathrm{As},\mathrm{P})}_{2}$ with emphasis on the ordered ${\mathrm{Eu}}^{2+}$ spin temperature region. The data indicate that i…
Position and number of the magnetic sensors affect the accuracy of the plasma shape identification algorithms. These algorithms usually solve an inverse problem based on the solution of the Grad-Shafranov equilibrium equation, and they need as input a certain number of magnetic field and flux measurements in points lo…
Regeneration of blood vessels has gained much focus for the treatment of cardiovascular disease, which is the primary cause of non-communicable disease death worldwide. American Heart Association reported an average of one death every 40 seconds, estimating the fatalities of more than 2150 Americans per day based on t…
Penelitian ini membahas tentang pengaruh jenis elektroda las dan sudut sambungan pada pengelasan Shielded Metal Arc Welding (SMAW) terhadap sifat mekanik material stainless steel 304 SS. Elektroda NSN-312 dengan sudut sambungan lasan 45 o diperoleh kekuatan maksimal (? u ) yaitu 39.97 kg/mm 2 dan kekutan luluh (? y )…

We describe the synthesis of architectures that consist of a symmetrical rodlike oligo(phenylene‐ethynylene) (OPE) backbone of incrementable length connected to a pair of classical ligands for metal coordination. OPE spacers decorated with various end groups and incorporating up to seven phenylene‐acetylene repeat uni…
The methods of transmission and reflection electron diffraction have been used to investigate the structure of Fe 3 O 4 films depending on the temperature of their synthesis on an Si substrate coated with an ultrathin layer of SiO 2 . The thus-grown polycrystalline films of magnetite had a texture, the axis of which w…
Nanostructures of ZnS/Cu/ZnS were deposited on glass substrate using physical vapor deposition technique. The thickness of the first and last ZnS layers was altered, while the thickness of the embedded Cu layer was fixed at 50 nm. The produced nanostructures were of good quality. Spectrophotometric measurements were c…
In this work, we report antibacterial activity of 3,6-di(pyridin-2-yl)-1,2,4,5-tetrazine (pytz) capped Pd(0) nanoparticles (TzPdNPs). The TzPdNPs were characterized by transmission electron microscopy (TEM) and powder X-ray diffraction techniques (PXRD). The antibacterial properties of TzPdNPs were studied using Gram-…
A new technique is presented for creating an electret from a plasma-enhanced chemical vapor deposition (PECVD) multilayer film of SiO2/Si3N4/SiO2. The technique uses a direct contact silicon electrode during poling. This thin-film electret formation process capitalized on deep traps in the silicon nitride, which is kn…
Electron energy loss (EEL) spectra of GeF 4 have been measured with incident electrons at 100 eV for 5° scattering angle and at 30 eV for 30° scattering angle, while sweeping the energy loss over the range 7.0–18.0 eV. Low-lying excited triplet, singlet, valence, and Rydberg states are investigated and the assignments…
A steel with a chemical composition meant to form nanostructured bainite following appropriate heat treatment, was, cooled rapidly from the liquid phase (1550°C) using melt spinning and modified injection-suction methods, as well as from a semi-solid temperature (1430°C) through thixoforming. The hardness of the as-ca…
