The Influence of Field‐Assisted Sintering Technology (FAST) Temperature and Cooling Rate on the Microstructural Evolution in Gamma‐Titanium Aluminide Alloy GE4822

open access: yesAdvanced Engineering Materials, EarlyView.
Controlling the Field Assisted Sintering Technology (FAST) parameters, dwell temperature and cooling rate, significantly influences the microstructural evolution in titanium aluminide GE4822. Significant γ‐lamellar colonies develop only upon cooling through the α‐transus.

Characterizing Interactions of Ionic Liquid Based Electrolytes with Electrospun Gas Diffusion Electrode Frameworks by 1H PFG NMR [PDF]

open access: yes, 2017
Pulsed field gradient (PFG) 1H NMR was used to characterize the mobility of ionic liquid cations in porous gas diffusion electrode (GDE) frameworks for metal–air electrochemical systems. The carbon GDE frameworks were produced by electrospinning.

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Diffusion in Cauchy Elastic Solid [PDF]

open access: yes, 2022
It is commonly accepted that a starting point of the science of diffusion is the phenomenological diffusion equation postulated by German physiologist Adolf Fick inspired by experiments on diffusion by Thomas Graham and Robert Brown.

Investigation on sound propagation for the measurement of diffusion in microporous solids. [PDF]

open access: yes, 2006
The basic definitions of micropore diffusivities and the experimental techniques applied for their measurement are reviewed. Through a historical perspective, the techniques are briefly described, with an emphasis on the measured property, the ...

Development of Methods of Gas Flow Computation in Short Diffusers

open access: yesProcedia Engineering, 2015
AbstractThe paper suggests numerical and experimental computation methods of gas flow in short diffusers. The results of numerical investigations, carried out in ANSYS CFX for thirteen variants of turbulence, as well as experimental results are presented. For turbulence model k-ω, good repeatability of experimental data is obtained.

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

open access: yesAdvanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Analysis of radial oscillations of gas bubbles in Newtonian or viscoelastic mediums under acoustic excitation [PDF]

open access: yes
Acoustic cavitation plays an important role in a broad range of biomedical, chemical and oceanic engineering problems. For example, kidney stone can be crushed into the powder (being discharged naturally) by the acoustic cavitation generated by carefully
