Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet

Advanced Materials, EarlyView.
Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, EarlyView.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

The Temple of Justice and the Key of David: Anachronism and Authority in the Chichester Seal Matrix

British Art Studies, 2017
In the early thirteenth century a new seal matrix was made for Chichester Cathedral. At its centre is an anachronistic architectural depiction, engraved underneath with the words “temple of justice”. The matrix’s combination of image and format is unique

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

Advanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Fast simulation of new coins from old

, 2005
Let S\subset (0,1). Given a known function f:S\to (0,1), we consider the problem of using independent tosses of a coin with probability of heads p (where p\in S is unknown) to simulate a coin with probability of heads f(p). We prove that if S is a closed

A COIN-CATCHER FOR REMOVING COINS FROM THE ESOPHAGUS [PDF]

JAMA: The Journal of the American Medical Association, 1913
The country doctor is often handicapped by lack of instruments. I was called to remove a nickel from the esophagus of a 2-year-old child and I had nothing in my armamentarium. nor could I find anything in those of my neighbors, with which I could remove the nickel. The simple device that I thought of is to be had in any town.

Tailor‐Made Protective LixAlSy Layer for Lithium Anodes to Enhance the Stability of Solid‐State Lithium–Sulfur Batteries

Advanced Materials Interfaces, EarlyView.
An intentionally added, chemically formed LixAlSy coating stabilizes the lithium–electrolyte interface in solid‐state Li–S batteries. The layer suppresses side reactions, preserves smooth charge transfer, and improves ion transport from the start. This approach offers a practical route to more durable solid‐state batteries and a clearer understanding ...

La didattica enattiva per una scuola dell’inclusione

Formazione & Insegnamento, 2017
Il repentino aumento del numero di alunni con cittadinanza non italiana ha scosso fino alle fondamenta la scuola. Molto è stato finora fatto per gestire il fenomeno nella sua iniziale fase di emergenza, ma molto resta ancora da fare per poter convivere ...

Multiscale Imaging Methodology for Surface Morphological Changes in Lithium Metal Anode Using Coupled Operando OM and In Situ EC‐AFM

Advanced Materials Interfaces, EarlyView.
A sequential multiscale imaging methodology integrates operando optical microscopy with in situ electrochemical atomic force microscopy to characterize lithium anode surface evolution during galvanostatic cycling under dual current densities. This unified approach enhances measurement consistency through correlative micro‐to‐nanoscale visualization ...
