Method and device for detection of surface discontinuities or defects [PDF]

open access: yes, 1974
Surface discontinuities of defects such as cracks and orifices are detected by applying a penetrating fluid, preferably a liquid, to a test surface so as to cause the liquid to penetrate any minute cracks or opening in the surface, removing the excess ...

Subsurface State Bilayer in Tetragonal Ferroelectric BaTiO3

open access: yesAdvanced Materials Interfaces
The interface is an issue in the ferroelectric field effect transistor. In this work, the study presents a combined characterization of the subsurface structure and the electric polarization of (001)‐oriented and poled BaTiO3 crystal sheets.

Stability and Behavior of Bulk Nanobubbles Under Reservoir Conditions

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Compared with microbubbles, nanobubbles exhibit superior stability, higher specific surface area, and smaller size. These characteristics have increasingly attracted the attention of petroleum researchers. However, existing literature lacks studies on nanobubble concentration and size under harsh reservoir conditions. To address this gap, this

Synergistic Effects of Co‐Activation Agents on an MnO–Activated Carbon Composite Electrode for Electrochemical Supercapacitors

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon materials synthesized from biomass are promising candidates for supercapacitor electrodes. Various activation processes for developing carbon materials with high surface areas have been investigated. Here, a manganese monoxide (MnO)–porous‐activated carbon (AC) composite was fabricated via the chemical activation of coconut shell by the

Leveraging Neural Operator and Sliding Window Technique for Enhanced Subsurface Soil Moisture Imputation Under Diverse Precipitation Scenarios

open access: yesJournal of Geophysical Research: Machine Learning and Computation
Environmental monitoring and decision‐making are sometimes hampered by missing sensor data, particularly in soil moisture (SM) records that underpin hydrological modeling, agricultural management, and climate studies.
