Investigation of solidification in zero-gravity environment: M553 sphere forming experiment. Nickel-silver alloy evaluation [PDF]
The processing of nickel-silver alloy specimens in space is discussed. Four specimens were melted only partially, while a fifth was melted completely and assumed after solidification a perfectly spherical shape.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work employs a dual‐effect function strategy of Se to make an original composite material of selenium (Se) and activated carbon (AC) (designated as Se–AC), as a functional iodine‐adsorbed cathode host. Not only Se catalyzes the I0/I− conversion reaction, but also Se nanoparticles can adjust the charge distribution of AC to adsorb more I3−. Aqueous‐

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.

The Dimensional Revolution of Phosphorus: From Allotropicity to Battery System Applications
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Phosphorus‐based materials are promising high‐capacity anodes classified by dimension (0D–3D) to systematically explore their properties and composite strategies. When combined with materials such as carbon to form heterostructures, the electrical conductivity and stability are effectively enhanced.

Deoxidation impact on the impurity index of heat resistant steel 40H15N7G7F2MS
Metalurgija, 2017 Analyzing failure causes of the parts made of heat resistant steel shows that one of the defining factors impacting the properties is concentration of harmful impurities both dissolved in steel and being in the form of nonmetallic inclusions. The latter,
