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

open access: yesAdvanced 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 regularity index and the depth of the tangent cone of curve singularities

open access: yesJapanese journal of mathematics. New series, 1996
The author studies numerical invariants of ``curves'', i.e. one-dimensional Cohen-Macaulay rings \((A,{\mathfrak m})\), and investigates their relation to the Cohen-Macaulay property of the tangent cone of \(R\), i.e. the associated graded ring \(\text{gr}_{\mathfrak m}(A)\).

Polish banking industry efficiency: a DEA window analysis approach [PDF]

open access: yes, 2006
The Polish banking industry has been transformed since the country’s transition to a market economy which began at the end of the 1980s. The industry has now developed and expanded to encompass more than 60 participants and it can thus be described ...

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Simulation study of rock-breaking performance of TBM cone-shape cutterhead under different tunneling parameters in spiral tunnel

open access: yesScience Progress
Compared with plane cutterhead, the cone-shape cutterhead has better rock-breaking performance with a free surface during the rock-breaking process. Tunneling parameters of cone-shaped cutterhead have great influence on the rock-breaking efficiency and ...

Influence of Disc Kinematic Regime Used in No Tillage Technology, on Germinative Bed Cone Index

open access: yes, 2010
This paper presents the disc velocity influence on soil cone index during no-tillage process. The practical research was done in laboratory conditions (soil bin) at the Hohenheim University, Stuttgart, Germany with three different coulters disc for no ...

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

open access: yesAdvanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

The Cone Index in soil mobilized after tractor traffic with bia-ply and radial tires and in four forward speeds [PDF]

open access: yes, 2007
The tractor is one of the machines that more traffics over the soil during the processes involving agricultural production. The interaction tractor/soil is made by the tires which, in most of the cases, are pneumatic. The tire type and the tractor travel
