Structure of amyloid-β (20-34) with Alzheimer's-associated isomerization at Asp23 reveals a distinct protofilament interface. [PDF]

open access: yes, 2019
Amyloid-β (Aβ) harbors numerous posttranslational modifications (PTMs) that may affect Alzheimer's disease (AD) pathogenesis. Here we present the 1.1 Å resolution MicroED structure of an Aβ 20-34 fibril with and without the disease-associated PTM, L ...

Metal‐Organic Frameworks Facilitating Complexation for Long‐Cycle Zinc‐Bromine Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The organic ligands (imidazole and benzimidazole) from the decomposed zinc ZIF‐62 is proposed to further improve the Br2 complexing ability of the mature complexing agent (i.e., N‐methyl‐N‐ethyl pyrrolidinium bromide (MEP) ionic liquid). The synergistic effect between Im/BIm of the decomposed ZIF‐62 toward bromine species and MEP toward bromine species,

Reconfigurable 3D Magnetic Nanoarchitectures

open access: yesAdvanced Functional Materials, EarlyView.
This experimental study confirms that 3D magnetic tetrapods grown by focused electron beam‐induced deposition exhibit sequential, controllable magnetization reversal in the individual nanowire legs. The magnetic state of the nanoarchitecture can be controlled individually, on‐demand, through a variation of the direction and magnitude of the applied ...
