PolyG Fibrils Coalesce Into Nuclear Ribbons That Engage Proteostasis Machinery in Neuronal Intranuclear Inclusion Disease. [PDF]

Adv Sci (Weinh)
In NIID, expanded NOTCH2NLC repeats give rise to nuclear polyG inclusions. Tracer‐guided in situ cryo‐electron tomography enables cross‐scale structural analysis from mouse brain to native neuronal nuclei, revealing dense‐core/peripheral‐halo inclusions built from compact polyG ribbons.

In-situ integrity control of frozen-hydrated, vitreous lamellas prepared by the cryo-focused ion beam-scanning electron microscope

, 2013
Recently a number of new approaches have been presented with the intention to produce electron beam transparent cryo-sections (lamellas in FIB-SEM terminology) from hydrated vitreously frozen cryo samples with a Focused Ion Beam (FIB) system, suitable ...

Optimized cryo-FIB milling strategy to generate thin, minimally damaged biological lamellae

bioRxiv
Focused ion beam (FIB)-milling has been adapted to thin frozen cells for visualization of macromolecular structures in situ with cryogenic electron microscopy. However, only a few large and abundant complexes have been annotated to date.

Low‐Pressure All‐Solid‐State Lithium–Sulfur Batteries: Challenges and Design Principles

Interdisciplinary Materials, EarlyView.
Stack pressure is redefined from an effective laboratory parameter to an external compensation for intrinsic interfacial incompatibility in all‐solid‐state lithium–sulfur batteries (ASSLSBs). This work links low‐pressure degradation to chemo‐mechanical mismatch among volume evolution, interfacial chemistry, charge transport, and mechanical response ...

Cryo-FIB lamellae enable ultra-high excitation laser intensities for cryogenic super-resolution fluorescence imaging

bioRxiv
Super-resolution cryogenic correlative light and electron microscopy (SR-cryo-CLEM) integrates molecular specificity and structure on the single-molecule level, but contemporary approaches require low laser powers to preserve specimen vitrification. Here,

Low Temperature Site‐Specific Pulsed Laser Annealing of MoS2

Small, EarlyView.
The application of laser pulses, of extremely short duration, is investigated as a potential new method to modify the atomic structure of ultrathin 2D materials for use in the creation of future electrical devices. The process is efficient, offering a site‐specific functionality, where regions of an electronic device that only requires annealing is ...

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively
