A high-resolution and large field-of-view scanner for in-line characterization of powder bed defects during additive manufacturing

Materials & Design, 2019
Powder bed defects are irregularities in the powder layer, which alter the energy input during the powder bed fusion process. As a result, they are directly responsible for the formation of flaws in the consolidated material, which cause quality and ...

Influence of various process conditions on surface finishes induced by the direct metal deposition laser technique on a Ti–6Al–4V alloy [PDF]

, 2012
The direct metal deposition (DMD) with laser is a free-form metal deposition process for manufacturing dense pieces, which allows generating a prototype or small series of near net-shape structures. One of the most critical issues is that produced pieces

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
