Abstract Soft neural electrode arrays that are mechanically matched between tissues and electrodes offer valuable opportunities for the development of disease diagnose brain computer interface systems. Here, a thermal release transfer printing method fabrication stretchable bioelectronics, such as soft arrays, is presented. Due to large, switchable irreversible change in adhesion strength tape, low‐cost, easy‐to‐operate, temperature‐controlled process can be achieved. The mechanism this...
The low-temperature aging treatment at 250°C can significantly improve the tensile superelasticity of NiTi alloys fabricated by electron beam directed energy deposition (EB-DED). However, it requires a very long duration (up to 200 h) achieve excellent due inherent coarse grain size. To accelerate process, high-density dislocations are introduced artificial thermal cycling prior (the original dislocation content in EB-DED processed is low), which will promote subsequent uniform precipitation...
Modification of HRB400E rebar has considered titanium inclusions during smelting to alter the microstructure and improve corrosion resistance, as evaluated using scanning electron microscopy, backscatter diffraction, high‐temperature confocal laser microscope analysis. The inclusion composition with Ti addition Si–Mn‐deoxidized steel follows sequence: SiO 2 –MnO → TiO –MnO–TiO . At higher content in steel, at completion refining were smaller size more numerous. grain three groups...
Noncommutative geometry may be a starting point to quantum gravity. We study the influence of spacetime noncommutative parameter on strong field gravitational lensing in Schwarzschild black-hole and obtain angular position magnification relativistic images. Supposing that supermassive central object galaxy described by this metric, we estimate numerical values coefficients observables for lensing. Comparing Reissner-Norstr\"{om} black hole, find influences is similar those charge, just these...
In order to solve the problem of forming liquid precipitated NbC when Nb is added excessively in high carbon steel. This study proposed introduce Ce form Ce-containing inclusions inhibit growth large NbC. The results show that strength valve spring steel with 0.63 % mass fraction, will be formed only if fraction exceeds 0.0192 %. When higher than 0.0364 addition formation melting point Ce2O3, Ce2C3 carbide at end solidification. And amount precipitation increase Ce2O3 and have low...
The extremely thin diameter of steel tire cord wire and saw are about 80 50 μm, respectively. It is supposed that this kind ultrafine easy to break due large hard nonmetallic inclusions in the during drawing standing process. This paper reviews research advances on inclusion microalloying elements control past 20 years. Including: 1) calculation thermodynamics formation quaternary system; 2) effects alkali metal alloys its oxides inclusions; 3) Ti‐containing SiO 2 ‐MnO‐Al O 3 inclusion; 4)...
Nowadays, under the context of severe resource shortage, it is urgent to develop non‐quenched and tempered steel. Herein, a new method combining rare‐earth cerium (Ce) magnesium (Mg) treat 49MnVS3 steel with low oxygen rather high sulfur proposed. The inclusions modification, microstructure evolution, mechanical properties change different Ce Mg content composite treatment are investigated by optical microscope (OM), scanning electron (SEM)–energy‐dispersive spectrometer (EDS), probe...
The effect of Ce on the microstructure, mechanical properties and corrosion resistance 27Cr-3.8Mo-2Ni super-ferritic stainless steel were investigated by FactSage 7.2, OM SEM. results reveal that when content increases from 0.00 wt-% to 0.0498 wt-%, Al2O3 inclusions wrapped irregular (TiNb)N are gradually modified into spheroidal CeAlO3, Ce2O3, Ce2O2S inclusions, rare earth smaller than 1.0 × 10−6 m (1.0 μm) dispersedly distributed. diameter recrystallized ferrite grain is decreased, steels...
A novel LF refining slag contains K2O has been developed in order to produce ultraclean saw wire steels. The diameter of ultrafine is between 50×10−6 m (50 µm) and 80 ×10−6 (80 µm), any hard inclusion which more than 5×10−6 (5 should be avoided because it probably will cause breaking. In enhance removal C96V steel during process, fundamental work on the effect alkali oxides (Li2O, K2O) absorption ability inclusions a typical for investigated. results indicated that additions seems...
In the present study, effect of cerium content in range 0~0.0676% on oxygen and sulfur content, as well quantity, size, distribution, type inclusions C104Cr saw wire steel, were investigated using thermodynamic analysis, metallographic examination, SEM-EDS, component analysis.

When steel 0.0136% or 0.0277%, main are...
We investigated the thermoelectric properties of phenalenyl-based molecular devices by using non-equilibrium Green's function method combined with density theory. The results show that performance device can be significantly improved different contact geometries. ZT value reach 1.2 at room temperature, which is two orders magnitude higher than graphene. Moreover, change coupling between molecule and electrodes also enhance value. further optimized to 1.4 300 K 5.9 100 owing decrease...
To clarify the effect of sulfur on inclusions and mechanical properties Ce-Mg treated resulfurized SCr420H steel. Laboratory experiments were conducted to prepare steels with contents as 0.01%, 0.06%, 0.132%. Inclusion evolution in liquid steel, MnS precipitation during solidification, tensile test results steel after quenching tempering investigated.
