Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

Deflection of High-Energy Cosmic Radiation Ions using a Bent Crystal Shield [PDF]
A bent crystal shield which is capable of deflecting cosmic radiation ions of all atomic numbers away from spacecraft using the ion channeling effect is described. Its effect on the transmitted angular distribution of heavy, high-energy ions is characterized using Monte Carlo channeling simulations.

Maillard Type Reaction for Electroless Copper Plating onto Ceramic Nanoparticles
This work presents the manufacturing of copper‐plated ceramic nanoparticles in an environmentally friendly way. Supported by organic functionalizations with pectin an electroless plating step can be performed. Sustainable reagents like xylose, and several amino acids are used for the reduction process.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Herein the metal‐to‐insulator transition is investigated when depositing vanadium dioxide (VO2) on glass or aluminum‐doped zinc oxide (AZO). O2 flow tuning during the deposition and additional post annealing are effective to control the metal‐to‐insulator transition. However, the VO2/AZO/glass stack reveals an increase in the transition temperature and

The burden of cystic fibrosis in North Africa
Background: Over 200 pathogenic variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene are associated with cystic fibrosis (CF)—the most prevalent autosomal recessive disease globally, the p.Phe508del variant being the most ...
