Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Effect of heat load on microstructural development in an irradiated low alloy steel
Nuclear Materials and Energy, 2018 To investigate the influence of heat load on microstructure change, we conducted in-situ experiments of annealing and irradiation for a model alloy (Fe-0.75Mn-0.47Mo-0.45Ni) using a multi-beam high voltage electron microscope.

Type conversion in electron-irradiated GaAs
Journal of Applied Physics, 1979 The unambiguous type conversion of GaAs by electron irradiation is reported here for the first time. Several high-quality n-type vapor-phase epitaxial layers (ρ?3 Ω cm and μ?7000 cm2/V sec at 300 K) were converted by 1-MeV electrons to high-quality p-type layers (ρ?30 Ω cm and μ?400 cm2/V sec).

Nanohardness of Electron Beam Irradiated HDPE [PDF]
Advanced Materials Research, 2014 Micromechanical changes in the surface layer of High-density polyethylene HDPE modified by beta radiation were measured by instrumented test of nanohardness. The specimens were prepared by injection technology and subjected to radiation doses of 0, 132, 165, 198 kGy.
