The small and medium scale industry in drilling and cutting sector widely use cutting tools made by High Speed Steel (HSS). The improvement of lifetime of HSS drill bits helps these establishments to achieve product economy. The improvement in the performance and service lifetime of high-speed steel (HSS) twisted dril…

On the basis of thieno(3,2-b)thiophene and dithieno[3,2-b:2′,3′-d]thiophene (T2 and T3 moieties) as π-linker, the A, D and S series dyes were designed to investigate the effect of the introducing N+ as an “electron trap” into T2 and T3 on the properties of the dyes. The optimized structures, electronic and optical pro…
Resistive switching devices are currently the best candidates realizing high-density flexible electronics for artificial intelligence because of simple structures, high density, high speed, and low-power consumption. However, few resistive switching devices contain both short-term memory and long-term memory behaviors…
Fe-Si composite coatings were electrodeposited with Fe-30wt%Si or Si particles on low silicon steel strips under a static magnetic field, the direction of imposed magnetic field kept parallel to electric field. The effects of magnetic field on the co-deposition process of magnetic Fe-30wt%Si particles and weak diamagn…
Abstract Organic solar cell of silol dithiophene based D2‐A‐D1‐A‐D2/PC71BM (D: donor part; A: acceptor part; 1 and 2 denote different units) possesses promising power conversion efficiency. Researchers have studied D2‐A‐D1‐A‐D2 molecules carefully, including the effects of the different number of terminal thiophenes,…
affinity chromatography, making it feasible to industrialize this highly active recombinant hyaluronidase which exhibited catalytic activity equal to that of the commercial enzyme. Therefore, this simple and effective isolation method could increase the availability of recombinant hyaluronidase for research and clinic…
Cellulose was isolated from plantain skin and then carboxymethylated with trichloroacetic acid which resulted a 0.9936 gram of carboxymethylcellulose. The FT-IR spectroscopy analysis of carboxymethyltricellulose indicated the –OH vibration at wavelength of 3448.72 cm-1.Moreover, a wavenumber in the region of 1026.13 c…
The synthesis and properties of 1,2,3,4-tetrahydro-1,4,5,8-tetraazaanthracene (THTAA) – a heterocycle involving both >N–H donating and =N– accepting moieties – have been reinvestigated. Unlike previously reported, THTAA is a thermally stable compound that can be re-sublimed at 300–310 °C without decomposition. Control…
Abstract Solution‐processed molybdenum oxide (MoO3–x) is a promising material for charge transport layer in optoelectronic devices. However, no clear relationship between oxidation state and electrical properties has been experimentally derived to guide the optimization of MoO3–x. Here, oxidation state of solution‐pro…
A grain boundary (GB) loop in a two-dimensional solid is the boundary of a domain or grain whose lattice orientation is mismatched with its uniform surroundings. Understanding the factors that influence the rate at which the interior of a GB loop relaxes to the orientation of its surroundings is an important step towa…
Abstract To investigate the effects of the cross section and notch radius of specimens on the susceptibility to hydrogen embrittlement of AISI 4140 steel at different hardness levels, the incremental step loading technique was used. Initially, the effect of the three factors on the fast force fracture strength values…
Comparison of the Performance of Lateral and Vertical InGaN/GaN-Based Light- Emitting Diodes with GaN and AlN Nucleation Layers Daesung Kang, Myunghoon Jung, Eunsil Choi et al. - Comparative study of GaN-based ultraviolet LEDs grown on different-sized patterned sapphire substrates with sputtered AlN nucleation layer S…
We present an experimental time-domain-spectroscopy study of the plasmonic resonance behavior of metamaterial surfaces in the terahertz regime. We determine the effective refractive index of the dielectric environment and its influence on meta-atoms built of connected dipoles. Our findings show that an analytical calc…
In the postulated severe accidents of nuclear power plants, the interaction mode of the molten corium with water happens differently depending on the height of the water level in the reactor cavity. The interaction of the molten corium with the partially filled water in the reactor cavity has been extensively studied.…
The influences of the crystal structure of Zr-doped lithium titanate prepared by the sol–gel method on the lithium ion diffusion coefficient and rate performance were studied. Compared with the pure phase Li4Ti5O[Formula: see text], Zr-doped lithium titanate presented a high discharge capacity as well as a good rate p…
Theoretically, crystals with supercells exist at a unique crossroads where they can be considered as either a large unit cell with closely spaced reflections in reciprocal space or a higher dimensional superspace with a modulation that is commensurate with the supercell. In the latter case, the structure would be defi…
Abstract We investigate the interaction between spin–orbit torque (SOT) and domain walls (DWs) created during magnetization reversal in perpendicularly magnetized ultrathin MnGa sandwiched between Ta and NiAl. We examine the out-of-plane hysteresis loops under various in-plane magnetic fields H x s along the current I…
Ge-containing zeolites were used as precursors for the synthesis of highly conductive and stable hybrid electronic materials by postsynthetic thermal treatment of the crystals in the presence of an olefin. Treating the as-prepared Ge zeolites in 1-butene at 700 °C formed a graphitic matrix within and outside the cryst…
Polypropylene is a potential material for the fabrication of superhydrophobic surfaces. In this paper, two isotactic polypropylenes made from a metallocene catalyst (miPP) and Ziegler–Natta catalyst (ziPP) were employed to prepare superhydrophobic surfaces. The results showed that the superhydrophobicity and thermal s…
