Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

Advanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Mechanism of Semi-Hydrogenation of Trace Acetylene in Ethylene by [MB12Hx]2-

Taiyuan Ligong Daxue xuebao
[Purposes] The main problem of semi-hydrogenation of trace acetylene in ethylene is excessive hydrogenation. High concentration of ethylene is the main cause of excessive hydrogenation, so it is important to design a catalyst with acetylene enrichment ...

A remarkable promoting effect of water addition on selective hydrogenation of p-chloronitrobenzene in ethanol

, 2007
Selective hydrogenation of p-chloronitrobenzene to p-chloraniline over ruthenium catalyst was found to be promoted remarkably (Selectivity: from 80.4% to 98.6%; TON: from 0.89 x 10(-2) s(-1) to 3.20 x 10(-2) s(-1)) by simply adding some water into the ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
