Indirect Estimation of Soil Shrink–Swell Susceptibility Using the Induced Polarization Geophysical Method [PDF]
E3S Web of ConferencesInduced polarization (IP) is based on the ability of a material to store electrical charges during the injection of a primary current. The accumulation and depletion of these charges decay once the primary current is shut off.

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres
Advanced Engineering Materials, EarlyView.This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

ABOUT THE REASONS FOR THE AMPLITUDE INCREASE OF THE SEISMOACOUSTIC OSCILLATIONS WITH FREQUENCIES OF THE HAZARD RANGE AT COAL SEAMS MINING [PDF]
, 2018 Determine the reasons for the amplitude increase (growth) of the seismoacoustic oscillations with frequencies of 700-1400 Hz in mine workings, which is one of the main criteria in the gas-dynamic phenomena ...

Application of Raman and Photoluminescence Spectroscopy to MgO‐C Refractories
Advanced Engineering Materials, EarlyView.Visible to near infrared luminescence of MgO is studied on MgO‐C bricks and nominally pure MgO powder, with focus on two similar sharp high‐intensity signals, at 699 and 871 nm, each surrounded by symmetrical sidebands. The nature of these sidebands is investigated by temperature‐dependent spectroscopic measurements, confirming phonon involvement by ...
