Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Further work at Kilise Tepe, 2007-11: refining the Bronze to Iron Age transition [PDF]

open access: yes, 2014
The excavations at Kilise Tepe in the 1990s inevitably left a range of research questions unanswered, and our second spell of work at the site from 2007 to 2011 sought to address some of these, relating to the later second and early first millennia. This

Nanodiamond‐Infused Microgels for pH‐Tunable Rheology, Lubrication, and UV Protection

open access: yesAdvanced Functional Materials, EarlyView.
Microgels consisting of swollen polyacrylic acid polymer networks, impregnated with nanodiamonds provide protection from ultraviolet (UV) radiation harmful to human health. Nanodiamonds enable UV blockage and control of the rheology (flow) and lubrication (skin‐feel) of these microgel‐skincare‐mimics.

Alésia : un nouvel atelier de bronzier dans le quartier des Champs de l’Église

open access: yesRevue Archéologique de l’Est, 2007
The oppidum of Alésia is located in the Côte-d’Or department in the village of Alise-Sainte-Reine. This site was occupied by a Gallo-roman agglomeration from the Ist century A.D. to the IVth century A.D. From 1997 to 2003, excavations were carried out at

Hittite Scribal Schools Outside of Hattusa? [PDF]

open access: yes, 2011
The article investigates the meagre textual evidence for Hittite scribal schools outside of Hattusa against the background of new excavations and the questions they raise about the social context of Hittite cuneiform writing. The use of the term é.dub.ba(

Field‐Free Spin–Orbit Torque Switching of Perpendicular Magnetization by PtTe2/WTe2 Bilayers at Sub‐ns Timescales

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates ultrafast, field‐free spin–orbit torque (SOT) switching using a PtTe2/WTe2/CoFeB multilayer, achieving sub‐nanosecond magnetization reversal with record‐low energy consumption. The PtTe2/WTe2 bilayer generates an intrinsic out‐of‐plane spin current, enabling deterministic switching without external fields.

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...
