Electrochemical and Biological Evaluation of Patterned TiO2@TiC‐Nanowires for Bio‐Interface Electrode

open access: yesSmall, EarlyView.
This study introduces a room‐temperature process to fabricate patterned TiO2@TiC core–shell nanowires, merging the biocompatibility of TiO2‐NWs with the high conductivity of TiC. Through sputtering pressure and time modulation, the nanowires morphology and electrochemical properties are tuned, enabling enhanced capacitance, stability, and guided ...

Vortex Domain Wall Imaging in a 3D Magnetic Nanotube Grown by Focused Electron Beam Induced Deposition

open access: yesSmall, EarlyView.
Synthesis of nanoscale high‐purity Co magnetic nanotubes using a single growth technique, focused electron beam induced deposition (FEBID). Utilizing electron holography and micromagnetic simulations, we demonstrate the nucleation and pinning of tilted vortex domain walls, providing crucial experimental evidence to advance 3D spintronics and ...

Quelques aspects de la formulation initiale des transformations de Lorentz (de Lorentz à Poincaré-Einstein)

open access: yes, 2019
Nous présentons ici quelques aspects naturels des transformations de Lorentz telles que formulées par ce dernier. Cette étude prend principalement sa source dans les documents originaux malheureusement pas assez consultés et utilise des mathématiques ...

Engineering Carbon Nanotube Quantum Well Defects With Recognition Tripeptides for Optical Detection of Extracellular Vesicles in Plasma

open access: yesSmall, EarlyView.
A three‐residue peptide bioconjugated onto a carbon nanotube quantum defect turns the near‐infrared emission of quantum defects into a reporter of integrins on intact extracellular vesicles, directly in human plasma. The sensor reveals that healthy fibroblast vesicles carry as much RGD‐binding integrin as cancer‐derived ones, an adhesion‐associated ...

Assessing Soft Reduction Effects on Centerline Macrosegregation in Continuous Casting Using Five Evaluation Metrics

open access: yessteel research international, EarlyView.
A comprehensive framework using five complementary metrics: macroetch assessment, 2D SMXRF mapping, 1D composition profiles, the segregation coefficient (Sc), and the maximum segregation value (Vmax) is presented for evaluating centerline macrosegregation in continuously cast steel slabs.
