Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Optic disc shape in patients with long-lasting unilateral esotropia and exotropia

BMC Ophthalmology, 2019
Background Horizontal eye movements have been proposed to induce biomechanical stress and strain on optic nerve head. Since strabismus may lead to sustained adduction or abduction, we investigate the effects of long lasting unilateral horizontal ...

A Cationic Supramolecule With Potent Antifungal Activity, Single‐Species Selectivity, and Strong Synergy With Echinocandins

Advanced Science, EarlyView.
We introduce a new membrane‐active antifungal design, Gua‐SMACS‐16, that exhibits high potency and single‐species selectivity for C. tropicalis while sparing other close species in the Candida genus. Moreover, when combining with caspofungin, a clinical antifungal drug inhibiting 1,3‐β‐glucan synthase, they exhibit ultra‐strong synergy across a panel ...

Data mining reactor fuel grab load trace data to support nuclear core condition monitoring [PDF]

, 2006
A critical component of an advanced-gas cooled reactor (AGR) station is the graphite core. As a station ages, the graphite bricks that comprise the core can distort and may eventually crack.

Investigation Into the Electrochemical Performance of Micron‐ and Nanosized Tin in Diglyme and Carbonate Electrolytes in Sodium Ion Batteries

Advanced Energy Materials, EarlyView.
This study compares Sn particles of different sizes in NIBs using carbonate‐ and diglyme‐based electrolytes. Diglyme electrolytes enable stable cycling despite large volume changes, while carbonate electrolytes degrade rapidly, especially with nanoparticles.

Cleaning Capacity Analysis of Foam Pig in Submarine Pipeline

Shiyou jixie, 2018
Elliptical submarine pipeline may reduce the contact area with the pig and thus affect the sealing effect, resulting in inferior cleaning effect. To analyze the cleaning capacity of the foam pig in the submarine pipeline, taking the foam pig cleaning ...
