A new way to explain the 511 keV signal from the center of the Galaxy and its possible consequences
, 2018 The first gamma-ray line originating from outside the solar system that was ever detected is the 511 keV emission from the center of our Galaxy. The accepted explanation of this signal is the annihilation of electrons and positrons.

A Novel Simplified Approach to Physically Simulate Wire‐Arc Directed Energy Deposition Conditions
Advanced Engineering Materials, EarlyView.Scarcity of specialized titanium alloy wires and high experimental wire production costs impedes wire‐arc directed energy deposition (waDED) adoption in industry. A novel, wireless approach is introduced to accelerate and economize titanium alloy development.

Advanced Engineering Materials, EarlyView.A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

(E)-2-(4-Nitrobenzylideneamino)benzamide
Acta Crystallographica Section E, 2009 The title compound, C14H11N3O3, adopts an E conformation, with a dihedral angle of 41.8 (1) ° between the mean planes of the two benzene rings. One of the amino H atoms forms an intramolecular hydrogen bond with the amide N atom, while

Atomic hydrogen: the quantum gas [PDF]
Physics World, 1995 It was a complete surprise when Isaac Silvera and his colleagues at the University of Amsterdam observed the existence of a remarkably stable gas of hydrogen atoms in 1979. They found that a gas of the so-called "atom of atoms" could be confined for several minutes in a cryogenic test cell close to absolute zero, provided that the walls were coated ...

Advanced Engineering Materials, EarlyView.Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.
