Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Photoemission study of the metal-insulator transition in VO_2/TiO_2(001) : Evidence for strong electron-electron and electron-phonon interaction

open access: yes, 2003
We have made a detailed temperature-dependent photoemission study of VO_2/TiO_2(001) thin films, which show a metal-insulator transition at \sim 300 K. Clean surfaces were obtained by annealing the films in an oxygen atmosphere.

Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

open access: yesAdvanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...

A Sustainability Approach between the Water–Energy–Food Nexus and Clean Energy

open access: yesWater
The excessive use of energy from fossil fuels, which corresponds to population, industrialisation, and unsustainable economic growth, is the cause of carbon dioxide production and climate change.

The phase diagram of high-Tc's: Influence of anisotropy and disorder

open access: yes, 1996
We propose a phase diagram for the vortex structure of high temperature superconductors which incorporates the effects of anisotropy and disorder. It is based on numerical simulations using the three-dimensional Josephson junction array model. We support

Mechanically Deposited Wear‐Resistant Amorphous Zr55Cu30Al10Ni5 Coatings

open access: yesAdvanced Engineering Materials, EarlyView.
Mechanically deposited from glassy ribbons, the Zr55Cu30Al10Ni5 amorphous coating formed a hard, continuous layer on AISI 1010 steel, tripling substrate hardness, lowering friction, and reducing wear. Despite its rough surface, it showed friction and wear behavior comparable to the crystalline alloy, highlighting its strong potential as a durable ...

Nitride‐Reinforced Metal Matrix Nanocomposite Powders Production by Plasma‐Assisted Thermochemical Treatment of Intermetallic Powders

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...
