The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

A carbon‐free, as‐sintered MgO–steel cermet anode, fabricated via cold isostatic pressing using MgO–C refractory recyclate, was evaluated under laboratory‐scale K‐cryolite electrolysis at 800°C. Operation at this reduced temperature, combined with the electrolyte's limited electrical conductivity, led to an increase in cell voltage.

Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Compact LET Arrays for Origami-Based Mechanisms
Lamina Emergent Torsional (LET) arrays can be used to replace creases in origami-based mechanisms. They can be made of planar materials, which makes them compatible with many designs.

REGULARITIES OF TITANIUM COMPACTS COMPACTION
The purpose of this paper is to establish the main regularities of compaction of titanium powders of ПТ5 grade at the stages of pressing and sintering as well as regularities of porosity distribution in sintered billets.

A Compact High-Efficiency Ultra-Wideband RF Rectifier for Electromagnetic Energy Harvesting
This paper proposed a compact and highly effective ultra-wideband rectifier for energy harvesting applications in radio frequency (RF) ambient. To reduce the complexity of the matching network, the rectifier adopted a matching network without reactance ...
