Abstract Achieving a functional and durable non-platinum group metal-based methanol oxidation catalyst is critical for cost-effective direct fuel cell. While Ni(OH) 2 has been widely studied as catalyst, the initial process of oxidizing to NiOOH requires high potential 1.35 V vs. RHE. Such would be impractical since theoretical cathodic oxygen reduction reaction at 1.23 V. Here we show that four-coordinated nickel atom able form charge-transfer orbitals through delocalization electrons near...
Traversing the Qinghai–Tibetan Plateau, Sichuan–Tibet Railway is by far most difficult railway project in world. The Plateau features active crustal dynamics on earth, strongest coupling effects of endogenic and exogenic dynamics, environment sensitive to global climate change. area characterized extremely cold climate, high elevation relief, seismic intensity, geothermal activity, tectonic stress. Consequently, threat various disaster risks ever-present at different stages entire life cycle...
Additive manufacturing of hard-to-weld nickel-based superalloys leads to the formation elongated columnar grain structures and hot cracks along build direction. Changing scanning strategy during selective laser melting (SLM) without changing alloy composition is a promising method for inhibition cracking by refinement. In this work, effect structure on behaviour Inconel 738 fabricated SLM with different strategies (rotation 0°, 90° 67° between layers, respectively) was investigated. Nearly...
In-depth understanding of corrosion behaviour is a key aspect regarding the application additively manufactured parts. In this study, 316L stainless steel was under different scanning strategies using selective laser melting (SLM). Microstructure characterization and electrochemical tests in NaCl aqueous solution (3.5 wt%), including open circuit potential (OCP), potentiodynamic polarization, impedance spectroscopy (EIS), were conducted to study influence on behaviour. The microstructure...
Abstract Cobalt oxyhydroxide (CoOOH) is a promising catalytic material for oxygen evolution reaction (OER). In the traditional CoOOH structure, Co 3+ exhibits low-spin state configuration ( $${t}_{2{{{{{\rm{g}}}}}}}^{6}{e}_{{{{{{\rm{g}}}}}}}^{0}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mrow> <mml:mi>t</mml:mi> </mml:mrow> <mml:mn>2</mml:mn> <mml:mi>g</mml:mi> <mml:mn>6</mml:mn> </mml:msubsup> <mml:mi>e</mml:mi> <mml:mn>0</mml:mn> </mml:math> ), with...
Overlapping melting trajectories and partially-melted powders result in poor surface morphology high roughness values (Ra = ~13.34 μm) of selective laser melted (SLMed) Ti6Al4V alloy. Secondary processing SLMed components is thus an essential finishing operation to produce functional parts precision engineering. This paper investigates the effects scanning strategies (0°, 67.5° 90° schemes) machining surfaces (top front surfaces) on performance alloy milling, compared with that annealed ASTM...
Machining processes have made technological leaps in achieving ultraprecision material removal and surface finishing at the submicrometric scale. At this level of precision, size effects dominated machining investigations while often been overlooked. The majority micromachining research works are ignorant potential implications that these phenomena bring as characteristic length approaches level. In review, physicochemical physical discussed by examining theoretical developments applications...
