Mesoporous Silica Microspheres by Super‐Fast Alkaline Etching of Micrometer‐Sized Stöber Particles

Advanced Engineering Materials, EarlyView.
Microscale silica particles are prepared along with a modified, scalable Stöber synthesis using the continuous addition of tetraethoxy silane to an ethanolic solution of ammonia with KCl. Etching with hydroxide ions at 95 °C gave porous analogs within minutes. Monodisperse particles are isolable in high yield after precipitation in ethanol.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior

Advanced Engineering Materials, EarlyView.
Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...

Titanium‐S23: A New Alloy with Ultra‐High Tensile Toughness Directly from the Solid‐State Processing of Recycled Ti–6Al–4V and Ti–5Al–5Mo–5V–3Cr Powders using Field Assisted Sintering Technology

Advanced Engineering Materials, EarlyView.
This study explores combining two existing aerospace titanium alloy powders, processing them via field‐assisted sintering technology and the subsequent discovery of a novel alloy composition, termed S23, with ultra‐high tensile toughness. Fine‐scale alpha precipitates favorably form in the alloy despite the relatively slow cooling, providing an ...

Mitigation of Cracks in High‐Performance Nickel‐Based Superalloys in Powder Bed Fusion Laser Beam of Metals Using a Metal Matrix Composite Approach

Advanced Engineering Materials, EarlyView.
High‐performance nickel‐based superalloys are often not processible in additive manufacturing (AM) due to hot cracking. The findings in this manuscript propose an efficient method to mitigate cracking and enhance mechanical properties of these alloys by producing a metal matrix composite, contributing to the material and process perspective of the AM ...
