Chemical doping with foreign atoms is an effective method to intrinsically modify the properties of host materials. In this paper, we report a facile strategy prepare nitrogen and boron doped monolayer graphene by using urea boric acid as solid precursors. By adjusting elemental precursors, content could be modulated from 0.9 4.8% for 0.7 4.3% respectively, estimated X-ray photoelectron spectroscopy. The mobilities graphene-based back-gate field-effect transistors are about 350–550 cm2 V−1...
Graphene was synthesized by chemical vapor deposition using polystyrene as the solid carbon source. The number of graphene layers could be controlled regulating weight under atmospheric pressure at 1000 °C. Silver nanoparticles were then deposited on a citrate reduction method. interaction between and silver investigated suface-enhanced Raman scattering spectra X-ray photoelectron spectroscopy. change in G band position indicates n-type doping due to an graphene. interlayer doped four-layer...
Neutron moderators, such as nuclear-grade graphite, are essential components of high-temperature nuclear reactors. Their primary functions to degrade the energy fission-born neutrons into an range that promotes further fission and serve central core structure. This paper will discuss historic reactor moderator materials, which relatively simple monolithic materials each having intrinsic benefits limitations. Additionally, a new class engineered composite moderators is presented for two...
Engineered composites composed of a radiation stable continuous matrix containing highly moderating entrained phase are attractive candidates for the realization bulk materials that structurally and neutronically superior to nuclear graphite. Here, we explore neutronics driven selection phases in MgO-based ceramic with focus on MgO-BeO system given its exceptional power high temperature stability. Using lithium-bearing salts as sintering aids, fully dense BeO loading up 40 vol.% produced...
With significant improvement in High Temperature Superconductors (HTS), several projects are adopting HTS technology for fusion power systems. Compact tokamaks offer potential advantages including lower plant costs, enhanced plasma control, and ultimately cost of electricity. However, as compact reactors have a reduced radial build to accommodate shielding, degradation due radiation damage or heating is potentially design limiting issue. Shielding must mitigate threats the superconducting...
Exploiting grain boundary engineering in the design of alloys for extreme environments provides a promising pathway enhancing performance relative to coarse-grained counterparts. Due its attractive properties as plasma facing material fusion devices, tungsten presents an opportunity exploit this approach addressing significant materials challenges imposed by environment. Here, we employ ternary alloy stabilizing W against recrystallization and growth while simultaneously manufacturability...
Controlling glass-glass interfaces in metallic nanoglasses is essential for tuning their mechanical properties and particular, the ability to inhibit severe strain localization through distributed shear band formation. In this paper, molecular dynamics are employed quantify structural characteristics of a scalable nanoglass model produced hydrostatic compression amorphous nanoparticles. Using framework distinguishing from grains based on correlation between dilatation atomic volume...
Deep learning methods, U-Net, UNet++, were applied to the analysis of single molecule movies obtained from liquid-phase electron microscopy.
Flight delay identification is an important way to coordinate the operation time of airport ground service providers and improve efficiency operations. By analyzing flight turnaround process, considering randomness synchronization using Colored Petri Nets Python (4.0.1), we explore correlation between various links in process take-off at next station.
